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, and the drawers are prone to tilting during the pulling process, affecting the user experience. Summary of the Invention

[0003] The present invention aims to at least solve 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, less labor-intensive, and improve door opening stability.

[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] A driving component is configured with a first transmission part, and the end of the driving component is configured with a force-applying part;

[0008] A door pusher, the door pusher having a third transmission part; the door pusher being adapted to switch between a concealed position and an extended position;

[0009] A transmission component is disposed between the push door component and the drive component; the transmission component is constructed with a second transmission component that drives the first transmission component and a fourth transmission component that drives the third transmission component; the transmission component drives the push door component to switch from the hidden position to the extended position according to the movement of the drive component.

[0010] A synchronizing element connects multiple push-door components along the length direction.

[0011] According to the door opening mechanism of this invention, the user applies force to the force-applying part to apply driving force to the driving member, causing the driving member to move. Since the transmission member has a second transmission part that drives and cooperates with the first transmission part of the driving member and a fourth transmission part that drives and cooperates with the third transmission part of the push-door member, as the driving member moves outward along the edge of the drawer body, the transmission member moves accordingly, thereby driving the push-door member from the hidden position to the extended position. The cabinet provides a reverse force to the push-door member, overcoming the door seal suction and moving the door assembly out, thus assisting in opening the door. Furthermore, the synchronizing member can drive multiple push-door members to move synchronously, providing opening assistance at multiple positions, ensuring that the door panel is evenly stressed at multiple positions, avoiding door panel tilting caused by applying force at a single position. Therefore, the embodiments of this invention are very labor-saving and allow for smooth door opening.

[0012] According to one embodiment of the present invention, the first transmission part includes a plurality of first meshing teeth distributed along a first arcuate path, the transmission member is configured with a pivot portion, and the second transmission part includes a plurality of second meshing teeth configured on the outer periphery of the pivot portion and distributed along a second arcuate path, so as to drive the pivot portion to rotate by the movement of the driving member along the first arcuate path.

[0013] According to one embodiment of the present invention, the driving member includes an arc-shaped sliding plate, and the first transmission part is disposed on one side of the arc-shaped sliding plate.

[0014] 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 lower edge of the flange is formed with the first transmission part.

[0015] According to one embodiment of the present invention, the force-applying part is constructed 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 extending direction of the force-applying part is less than or equal to 90°.

[0016] According to one embodiment of the present invention, the fourth transmission part includes a fourth meshing tooth constructed on the outer periphery of the pivot portion, the fourth meshing tooth being distributed along a third arcuate path, the first distance of the fourth meshing tooth to the pivot portion being less than the second distance of the second meshing tooth to the pivot portion, and the third transmission part includes a third meshing tooth distributed along the movement direction of the push door member.

[0017] According to one embodiment of the present invention, the synchronizing element and the transmission element are driven by meshing.

[0018] According to one embodiment of the present invention, when the transmission member is configured with a pivot portion and the second transmission portion includes a plurality of second meshing teeth configured on the outer periphery of the pivot portion and distributed along a second arcuate path, the synchronizing member engages with the second transmission portion for transmission.

[0019] According to one embodiment of the present invention, both ends of the synchronizing member are provided with the driving member, the transmission member and the door pusher, and the force-applying parts of the two driving members are connected by a synchronizing plate.

[0020] 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.

[0021] According to a second aspect of the present invention, a door assembly includes a door panel and an opening mechanism as described above, wherein the drive member is slidably mounted on the door panel.

[0022] According to one embodiment of the present invention, when the driving members are provided on both sides of the synchronizing member, the two driving members are located at both ends of the door panel.

[0023] According to one embodiment of the present invention, the door panel is configured with a guide portion extending along the movement path of the drive member, and the drive member is movably connected to the guide portion.

[0024] According to one embodiment of the present invention, when the door opening mechanism further includes a reset member, the reset member is a torsion spring, the first torsion arm of the torsion spring is limited to the door panel, and the second torsion arm of the torsion spring is limited to the transmission member and rotates with the pivot of the transmission member.

[0025] According to a third aspect of the present invention, a storage cabinet includes a cabinet body and at least one drawer, the cabinet body forming a cavity corresponding to the drawer; the drawer includes a drawer body and a door assembly as described above, the drawer body is pull-out disposed in the cavity, the drawer body has a door panel fixed to the side wall of the drawer body facing away from the cavity, and the edge of the door panel abuts against the cabinet body.

[0026] The above-described one or more technical solutions in the embodiments of the present invention have at least one of the following technical effects:

[0027] The door opening mechanism of the present invention includes a driving component, a transmission component, a pushing component, and a synchronizing component. The driving force of the driving component is transmitted to the pushing component through the transmission component, so that the pushing component switches from a hidden position to an extended position. By setting the transmission component, the direction of the driving force provided by the driving component can be changed to ensure that the pushing component in the extended position can abut against the cabinet and push the door panel out through the reaction force provided by the cabinet. The synchronizing component connects multiple pushing components so that the pushing force is applied to multiple positions. When the door needs to be opened, the user applies force to the force-applying part, which in turn applies driving force to the drive component, causing the drive component to move. Since the transmission component has a second transmission part that engages with the first transmission part of the drive component and a fourth transmission part that engages with the third transmission part of the push-door component, as the drive component moves outward along the edge of the drawer body, the transmission component moves accordingly, thereby driving the push-door component from the hidden position to the extended position. The cabinet provides a counterforce to the push-door component, overcoming the door seal suction and moving the door assembly out, thus assisting in opening the door. Furthermore, the synchronizing component can drive multiple push-door components to move synchronously, providing opening assistance at multiple positions, ensuring that the door panel is evenly stressed at multiple positions, avoiding door panel tilting caused by applying force at a single position. Therefore, the embodiments of the present invention are simple in structure, convenient in operation, very labor-saving, and enable smooth door opening.

[0046] Combination Figures 1 to 6 As shown, an embodiment of the present invention provides a door opening mechanism, which includes a driving member 100, a pushing member 300, a transmission member 200, and a synchronizing member 400. The driving member 100 has a first transmission section, and a force-applying section 103 is formed at its end. The pushing member 300 has a third transmission section and is adapted to switch between a concealed position and an extended position. The transmission member 200 is disposed between the pushing member 300 and the driving member 100. The transmission member 200 has a second transmission section that drives the first transmission section and a fourth transmission section that drives the third transmission section. The transmission member 200 is used to drive the pushing member 300 from the concealed position to the extended position according to the movement of the driving member 100. Multiple pushing members 300 are connected along the length of the synchronizing member 400.

[0047] In this embodiment, the user applies force to the force application part 103, thereby applying driving force to the drive member 100, causing the drive member 100 to move. The movement of the drive member 100 is transmitted to the push door member 300 through the transmission member 200, driving the push door member 300 from a hidden position to an extended position. During the process of switching from the hidden position to the extended position, the push door member 300 provides pressure to the cabinet on which the door assembly is installed, and the cabinet provides a counterforce to the push door member 300, overcoming the door seal suction and assisting in opening the door. Furthermore, by setting a synchronizing member 400, multiple push door members 300 can be driven to move simultaneously, that is, multiple push door members 300 abut against the cabinet and assist in opening the door in multiple positions.

[0048] The terms "hidden position" and "extended position" refer to the state in which the door opening mechanism is installed on the door panel. The hidden position can be understood as the door pusher 300 being concealed within the door panel 800 and not protruding from its end face; the extended position can be understood as the door pusher 300 protruding from the door panel 800. The transmission mechanism 200 can be a rotary drive, belt drive, chain drive, linkage drive, or a combination of these transmission methods. The function of the transmission mechanism 200 is to switch the direction of movement of the drive mechanism 100 to the direction of the door pusher 300 from the hidden position to the extended position. Figure 4 As shown, the transmission component 200 converts the rightward movement of the drive component 100 into the leftward movement of the push-door component 300.

[0049] The door opening mechanism of this embodiment achieves assisted door opening through the cooperation of the driving component 100, the transmission component 200, the pushing component 300, and the synchronizing component 400. The synchronizing component 400 can also provide simultaneous assistance from multiple positions and ensure synchronized movement of the pushing component 300. This door opening mechanism can be applied to various devices, such as drawer doors, storage cabinet doors, vending machine doors, display cabinet doors, and refrigerator doors.

[0050] The working principle of the door opening mechanism in this embodiment will be explained below, taking the application of the door opening mechanism in a refrigerator pull-out drawer as an example:

[0051] The pull-out drawer includes a drawer body (not shown in the figure) and a door panel 800. The drawer body and door panel 800 define a receiving cavity with an opening at the top. The door panel 800 is fixed to the front end of the drawer body, and the edge of the door panel 800 protrudes from the drawer body. That is, 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 on the left and right sides of the projected area of ​​the drawer body. The drive component 100 is slidably mounted on the side edge of the door panel 800. The transmission component 200 and the door pusher 300 are installed 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 drive component 100, transmission component 200, and door pusher 300 are connected to the left and right sides of the drawer body. The pull-out drawer is installed in the refrigerator cabinet. When the pull-out drawer is closed, the edge of the door panel 800 abuts against the cabinet.

[0052] When the pull-out drawer needs to be opened, the user only needs to apply a pulling force to the force application part 103 of the drive component 100 to gently pull the drive component 100 outward. Since the transmission component 200 is connected to both the drive component 100 and the push-door component 300, as the drive component 100 is pulled away from the cabinet relative to the door panel 800, the transmission component 200 moves accordingly, thereby causing the push-door component 300 to extend towards the cabinet, that is, the push-door component 300 moves from the hidden position to the extended position. During this process, the push-door component 300, due to the obstruction of the cabinet, applies a forward pushing force to the door panel 800, thereby overcoming the door seal suction and assisting in opening the door. It can be seen that compared to traditional drawers where the user directly pulls the door panel 800 of the pull-out drawer, the pulling force applied by the user in this embodiment is much smaller and less strenuous.

[0053] like Figure 2 and Figure 3 As shown, the transmission component 200 transmits the motion of the drive component 100 to the push door component 300 through rotation, making user operation more effortless. The transmission component 200 is constructed with a pivot portion 203, which rotates relative to the door panel 800. The first transmission component is used to drive the rotational movement of the second transmission component. The pivot portion 203 is a shaft or a hole, such as a rotating shaft or a bushing.

[0054] The driving component 100 and the transmission component 200 are driven by meshing, that is, the first transmission part and the second transmission part are driven by meshing. The first transmission part is constructed with a first meshing tooth, and the second transmission part is constructed with a second meshing tooth. The meshing transmission has high transmission accuracy and accurate positioning.

[0055] At this time, the second transmission part includes a plurality of second meshing teeth 201 and a plurality of second meshing grooves constructed on the outer periphery of the pivot 203 and distributed along the second arc-shaped path. The second meshing teeth 201 have a rotation radius of distance to the rotation axis of the pivot 203, that is, the second arc-shaped path is a path formed with the rotation radius of the second meshing teeth 201 as the radius. The second transmission part of the transmission member 200 is connected to the pivot 203 through a fan-shaped plate portion to ensure the structural strength of the transmission member 200.

[0056] like Figure 2 and Figure 3 As shown, the first transmission part of the drive member 100 includes a plurality of first meshing teeth 102 and a plurality of first meshing grooves distributed along a first arc-shaped path. The first meshing teeth 102 mesh with the second meshing grooves, and the second meshing teeth 201 mesh with the first meshing grooves. That is, the user can drive the transmission member 200 to rotate by pulling the drive member 100 along the first arc-shaped path, which is easy to operate.

[0057] It should be noted that the first meshing teeth of the drive component can also be distributed along a straight path (not shown in the figure). In this case, the drive component moves in a straight line to drive the transmission component to rotate, and the user can pull the drive component to provide driving force. The movement mode of the drive component can be selected as needed.

[0058] When the door opening mechanism is applied to a pull-out drawer, the drive component 100 is slidably connected to the door panel 800. When the user pulls the drive component 100 outwards along the side edge of the door panel 800, the drive component 100 slides outwards, causing the transmission component 200 to rotate and drive the push-door component 300 to extend towards the cabinet, that is, the push-door component 300 moves from the concealed position to the extended position. The driving force acting on the drive component 100 is consistent with the direction of the force applied by the user when pulling the pull-out drawer outwards, facilitating user operation.

[0059] like Figure 2 As shown, the door opening mechanism is set at the upper end of the door panel 800 as an example. However, the position of the door opening mechanism is not limited to the upper end of the door panel 800. It can also be at the lower end or other positions.

[0060] Related embodiments of the drive component 100 structure are provided.

[0061] The drive unit 100 includes an arc-shaped slide plate 101. A first transmission part is provided on one side of the arc-shaped slide plate 101, that is, a plurality of first meshing teeth 102 distributed along a first arc-shaped path are provided on one side of the arc-shaped slide plate 101. When the drive unit 100 is pulled, the movement trajectory of the arc-shaped slide plate 101 is an arc-shaped movement towards the user and biased upward. The direction of force application is more in line with ergonomics, so that the user has a better sense of effortless movement.

[0062] The first transmission unit can be integrally formed on the arc-shaped slide plate 101 or detachably connected to the arc-shaped slide plate 101, as described in the following embodiments. However, the structure of the arc-shaped slide plate 101 is not limited to the following forms.

[0063] The first structural form of the curved sliding plate 101: 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 tooth 102 and a first engaging groove are formed at the lower edge of the flange. Figure 2 For example, the curved sliding plate 101 includes two long sides extending along its length. These two long sides form a first plate and a second plate that bends downwards relative to the first plate. The first plate is located on the side edge of the door panel 800 (such as the left or right side edge) and extends to the outside of the side edge of the door panel 800. The rear half of the second plate forms a flange. The central angle of the curved sliding plate 101 is not less than 70° to facilitate user application of force. Furthermore, a groove is formed at the upper end of the flange, through which the curved sliding plate 101 is slidably connected to the door panel 800 or the drawer body.

[0064] The second structural form of the curved sliding plate 101: A groove is formed between the two side walls of the curved sliding plate 101, allowing the curved sliding plate 101 to slide smoothly onto the door panel 800 or the drawer body. The lower end of one side wall of the curved sliding plate 101 is formed with a first meshing tooth 102 and a first meshing groove, eliminating the need for a flange.

[0065] The third structural form of the arc-shaped slide plate 101: The lower edge of the arc-shaped slide plate 101 is detachably connected to a plurality of first meshing teeth 102 and a plurality of first meshing grooves distributed along the first arc path, so as to facilitate the adaptation of first meshing teeth 102 and first meshing grooves of different sizes.

[0066] In some embodiments, the force-applying portion 103 is a protrusion formed at the first end of the arc-shaped slide plate 101, and the angle between the tangent direction of the first end of the arc-shaped slide plate 101 and the extending direction of the force-applying portion 103 is less than or equal to 90°, that is, the force-applying portion 103 is inclined from bottom to top toward the second end of the arc-shaped slide plate 101. The first end and the second end are the two ends along the length of the arc-shaped slide plate 101, such as... Figure 4 and Figure 5As shown, the first end is the right end of the curved sliding plate 101, and the second end is the left end of the curved sliding plate 101. The advantages of this design are twofold: Firstly, it facilitates user application of force. When the user opens the straight-pull drawer, the curved sliding plate 101 moves in an arc towards the user and slightly upwards. Compared to a straight-line movement towards the user or an arc-shaped movement slightly downwards, the movement trajectory of this invention and the inclined setting of the force-applying part 103 prevent the user's fingers from accidentally slipping off the force-applying part 103 during the pulling of the drive component 100. It also eliminates the need for the user to bend over excessively, allowing the user to easily apply opening force while standing comfortably. Furthermore, because the direction of the force is more ergonomic, it provides a better sense of effortless operation. Secondly, it prevents the force-applying part 103 from snagging on other items, such as the user's clothing. It should be noted that even with the force-applying part 103 set parallel to the door panel 800, the aforementioned technical effects can still be achieved effectively simply by designing the curved movement trajectory of the curved sliding plate 101.

[0067] The following provides relevant embodiments of the transmission component 200.

[0068] like Figure 2 and Figure 5 As shown, the fourth transmission part of the transmission member 200 includes a fourth meshing tooth 202 and a fourth meshing groove constructed on the outer periphery of the pivot part 203. The fourth meshing tooth 202 is distributed along a third arc-shaped path. The third transmission part includes a third meshing tooth 301 and a third meshing groove distributed along the movement direction of the push door member 300. The fourth meshing tooth 202 meshes with the third meshing groove, and the fourth meshing groove meshes with the third meshing tooth 301. The meshing transmission has high transmission accuracy. The fourth transmission part is also connected to the pivot part 203 through a fan-shaped plate.

[0069] The first distance from the fourth meshing tooth 202 to the pivot 203 is less than the second distance from the second meshing tooth 201 to the pivot 203. The torque of the second transmission part and the fourth transmission part of the transmission member 200 is the same. By adjusting the first distance and the second distance, the force transmitted by the fourth meshing tooth 202 and the second meshing tooth 201 can be adjusted. If the first distance is less than the second distance, the driving force provided by the drive member 100 is less than the force transmitted to the push door member 300. In other words, the transmission member 200 amplifies the driving force and transmits it to the push door member 300, making the user's operation more effortless.

[0070] When the second distance is greater than or equal to twice the first distance, the transmission component 200 can amplify the user's pulling force, enabling the door pusher 300 to obtain a greater pushing force, thereby achieving a better labor-saving effect.

[0071] Taking the pull-out drawer as an example again, Figure 4 and Figure 5Based on the indicated orientation, the pivot 203 of the transmission component 200 is rotatably mounted on the side wall of the door panel 800 or the drawer body. When the user applies a rightward pulling force to the force-applying part 103 of the drive component 100, the first transmission part of the drive component 100 continuously engages with the second transmission part, thereby driving the second transmission part to rotate clockwise. Since both the second and fourth transmission parts are constructed on the outer periphery of the pivot 203, the fourth transmission part rotates clockwise synchronously during the clockwise rotation of the second transmission part. During the rotation of the fourth transmission part, it continuously engages with the third transmission part of the push door component 300, thereby driving the push door component 300 to move to the left, that is, from the hidden position to the extended position. After being blocked by the cabinet, the push door component 300 applies a rightward reaction force to the pull-out drawer, causing the entire pull-out drawer to pop out to the right from the cabinet.

[0072] It should be noted that, in addition to the drive component 100, transmission component 200, and push-door component 300 being driven by meshing transmission to move the push-door component 300 from the concealed position to the extended position, other structures can also be used to achieve the same result. For example, the transmission component can be a belt drive structure or a chain drive structure, which can reverse the driving force of the drive component and transmit it to the push-door component. Alternatively, the transmission component 200 can mesh with the drive component 100, and the transmission component 200 can be driven by the push-door component 300 through a linkage assembly (not shown in the figure). In this case, the transmission component 200 is constructed with a pivot portion 203, a second meshing tooth, and a second meshing groove. The linkage assembly includes a first link and a second link. One end of the first link is fixedly sleeved on the pivot portion 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 sliding groove extending along the drawer body's pulling direction, and the push-door component 300 is slidably embedded in the sliding groove. Therefore, when the user applies an outward pulling force to the force-applying part 103 of the drive member 100, the first transmission part of the drive member 100 engages with the second transmission part of the transmission member 200, thereby driving the transmission member 200 to rotate clockwise. Since the end of the first connecting rod is fixedly sleeved on the pivot part 203, during the clockwise rotation of the transmission member 200, the first connecting rod rotates clockwise with the pivot part 203, thereby pushing the push door member 300 to move to the left along the slide groove through the second connecting rod.

[0073] The following provides examples related to synchronization components.

[0074] To ensure even force distribution on both sides of the drawer body and prevent insufficient reaction force from the sliding door component 300 when force is applied to a single location, which could cause the drawer body to tilt, the synchronizing component 400 can connect multiple sliding door components 300. One sliding door component 300 moves under the action of the driving component 100, driving the other sliding door components 300 connected to the synchronizing component 400 to move synchronously. The synchronizing component 400 can be a long, strip-shaped structure such as a rod-like or plate-like structure.

[0075] Unlike the above-described implementation method, as follows: Figure 1 As shown, multiple sets of transmission components 200 and push door components 300 are arranged along the length of the synchronizing component 400. The synchronizing component 400 is in transmission cooperation with the transmission components 200, and the synchronizing component 400 ensures that multiple transmission components 200 move synchronously, thereby causing multiple push door components 300 to move synchronously, thus preventing the drawer body from tilting.

[0076] Based on the above embodiments, multiple sets of drive members 100, transmission members 200 and push door members 300 are combined and arranged in the length direction of synchronization members 400. The transmission members 200 are equipped with drive members 100 and are driven and cooperated with the transmission members 200 through the synchronization members 400 to ensure that multiple transmission members 200 drive the push door members 300 to move synchronously.

[0077] Of course, in the length direction of the synchronizing component 400, the number of driving components 100 can be less than the number of transmission components 200, which can be set according to the specific needs.

[0078] like Figure 1 As shown, the synchronizing element 400 is fixedly connected to the synchronizing pulleys 500 at both ends. Both ends of the synchronizing element 400 are provided with a transmission element 200 and a push-door element 300. At least one end of the synchronizing element 400 is provided with a driving element 100. The transmission element 200 is in transmission cooperation with the synchronizing pulleys 500. The synchronizing pulleys 500 can be, but are not limited to, a synchronizing gear, a synchronizing sprocket, or a synchronizing belt pulley.

[0079] When the synchronous pulley 500 is a synchronous gear, the transmission component 200 meshes with the synchronous pulley 500 for transmission. The transmission component 200 is constructed with a fifth transmission part extending along an arc-shaped path. The fifth transmission part and the second transmission part both extend along a second arc-shaped path and form continuously distributed meshing teeth and meshing grooves, which facilitates the machining and forming of the transmission component. For example, as... Figure 2 As shown, the transmission component 200 includes a second meshing tooth and a fifth meshing tooth distributed along a second arc-shaped path. The meshing tooth distributed along the second arc-shaped path meshes with both the drive component 100 and the synchronizing gear. Therefore, when the user applies an outward pulling force to the force-applying part 103 of the drive component 100, the first meshing tooth 102 of the drive component 100 continuously meshes with the second meshing groove, thereby driving the transmission component 200 to rotate clockwise. Simultaneously, the fifth meshing tooth continuously meshes with the tooth groove of the synchronizing gear, thereby driving the synchronizing gear to rotate counterclockwise. Due to the presence of the synchronizing component 400, the transmission component 200 is ensured to always rotate in the same direction, thus ensuring that the push door component 300 maintains synchronized movement.

[0080] The extension path of the fifth transmission unit may differ from that of the second transmission unit, and can be set as needed.

[0081] When the synchronous pulley 500 is a synchronous belt pulley, a synchronous belt is also provided between the transmission component and the synchronous belt pulley. The transmission pulley can be fixedly sleeved on the pivot part 203, and the transmission pulley and the synchronous belt pulley are connected by the synchronous belt. Thus, when the user applies an outward pulling force to the force application part 103 of the drive component 100, the drive component 100 drives the transmission component 200 to rotate clockwise, the transmission pulley rotates clockwise accordingly, and in turn drives the synchronous belt pulley to rotate clockwise. Due to the presence of the synchronous component 400, the synchronous belt pulley connected to the synchronous component 400 always maintains synchronization and rotates in the same direction, thereby making the push door component 300 maintain synchronous movement.

[0082] like Figure 1 and Figure 6 As shown, at least two drive members 100 are provided along the length of the synchronizing member 400, and the force-applying part 103 of the drive member 100 is connected through the synchronizing plate 600. The advantage of this arrangement is that it can ensure the force balance of the transmission member 200 and facilitate the user to pull the drive members 100 simultaneously. The synchronizing plate 600 and the force-applying part 103 are detachably connected, and the connection method can be plug-in, snap-fit, or threaded connection.

[0083] Both ends of the synchronizing component 400 are equipped with driving components 100. The force-applying parts 103 of the two driving components 100 are connected by the synchronizing plate 600, which can ensure that the two transmission components 200 are balanced by force and make it convenient for the user to pull the two driving components 100 at the same time.

[0084] like Figure 1 As shown, the drive component 100, transmission component 200 and push-door component 300 are respectively set at both ends of the synchronization component 400, that is, set at both ends of the door panel 800. This ensures that the structure at both ends of the door panel 800 is symmetrical, so as to provide uniform assistance to the opening process of the straight-pull drawer, and also facilitates the installation of the drive component 100, transmission component 200 and push-door component 300.

[0085] In addition, the door opening mechanism also has an automatic reset function, that is, the door opening mechanism also includes a reset component, which is used to drive the push door component 300 from the extended position to the retracted position. In order to achieve the automatic reset of the push door component 300, the reset component can adopt various structural forms.

[0086] The structural form of the reset component is provided below.

[0087] Form 1, such as Figure 2As shown, the reset component includes a torsion spring 700. The first torsion arm of the torsion spring 700 is limited to the door panel 800, and the second torsion arm of the torsion spring 700 is limited to the transmission component 200 and rotates with the pivot part 203. During the process of the drive component 100 driving the transmission component 200 to rotate clockwise, the torsion spring 700 undergoes torsional deformation. When the user releases the drive component 100, the transmission component 200 rotates counterclockwise under the drive of the restoring force of the torsion spring 700, thereby driving the drive component 100 to slide inward toward the door panel 800, that is, the drive component 100 slides toward the receiving cavity of the drawer body. At the same time, the push door component 300 moves from the extended position to the hidden position under the drive of the transmission component 200, realizing automatic reset. Thus, after the user takes items out of the pull-out drawer, they can directly push the pull-out drawer back into the cabinet.

[0088] A torsion spring 700 is fitted onto the pivot joint 203, and the two torsion arms of the torsion spring 700 are respectively limited to the transmission component and the door panel 800 (or the drawer body). For example... Figure 2 and Figure 3 As shown, the side wall of the door panel 800 is provided with a protrusion for limiting the first torsion arm, and the side wall of the transmission component 200 can be provided with a protrusion 204 for abutting the second torsion arm. The door panel 800 has a relief groove 802 for the protrusion 204 to rotate, which provides rotation space and guides and limits the protrusion 204. Of course, the side wall of the door panel 800 or the drawer body can also be provided with a protrusion for abutting the torsion spring 700, and the position of the protrusion can be selected as needed.

[0089] 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. A guide rod extending into the mounting cavity is formed on the end face of the push door component 300 away from the cabinet body, extending along the pulling direction of the push door component 300. A mounting protrusion extending into the mounting cavity is formed on the side wall of the drawer body, and the mounting protrusion is positioned opposite 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. Therefore, as the 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 a concealed position to an 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 them is continuously compressed. When the user releases the drive component 100, the push door component 300 is no longer driven by the 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 pull-out drawer, he can simply push the pull-out drawer into the cabinet.

[0090] Method 3: The reset component includes a first magnetic component and a second magnetic component. The first magnetic component is fixedly installed on the push door component 300, and the second magnetic component is fixedly installed on the door panel or drawer body. During the process of the push door component switching from the hidden position to the extended position, the repulsive force between the first magnetic component and the second magnetic component increases, contacting the driving force of the drive component. The push door component then returns to the hidden position under the action of the repulsive force. For example, the push door component 300 has a mounting cavity, with the side of the mounting cavity facing the drawer body open. The side wall of the drawer body has a mounting protrusion extending 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, during the process of the drive component 100 driving the push door component 300 to move to the left through the transmission component 200, that is, during the process of the push door component 300 moving 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 drive mechanism 100, the sliding door 300 is no longer driven by the drive mechanism 100 through the transmission mechanism 200. At this time, driven by the repulsive force exerted by the second magnetic component, the sliding door 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.

[0091] 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 drive component 100, which drives the transmission component 200 to rotate counterclockwise, and the transmission component 200 then drives the push door component 300 to move to the right from the extended position to the hidden position.

[0092] It should be noted that, in addition to the structural forms described above, the drive component 100, transmission component 200, and 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 transmission part; the top of the driven rod abuts against the curved surface segment of the cam; the sidewall 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; the driven gear meshes with the toothed groove of the driven rod and the push rack, respectively. Therefore, when the drive unit 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.

[0093] like Figures 1 to 6 As shown, this embodiment of the invention also provides a door assembly, which includes a door panel 800 and the aforementioned door opening mechanism, with a drive member 100 slidably mounted on the door panel 800.

[0094] To improve aesthetics and achieve a fully continuous effect, with driving components 100 on both sides of the synchronizing component 400, the distance between the back faces of the two driving components 100 is equal to the width of the door panel 800, meaning that the two driving components 100 are located at the two ends of the door panel 800 respectively.

[0095] like Figure 2 and Figure 5 As shown, the door panel 800 is constructed with a guide portion 801 extending along the movement path of the drive member 100. The drive member 100 is movably connected to the guide portion 801. The guide portion 801 guides the movement process of the drive member 100 and can improve the stability of the drive member 100.

[0096] When the drive member 100 moves along the first arc-shaped path, the guide portion 801 is a groove or protrusion extending along the first arc-shaped path, and the drive member 100 is constructed with a matching protrusion or groove accordingly. If the drive member 100 is constructed with an arc-shaped slide plate 101, then the side of the arc-shaped slide plate 101 facing the guide portion 801 is constructed with a matching protrusion or groove.

[0097] like Figure 2 As shown, the door opening mechanism also includes a reset component, which is a torsion spring 700. The first torsion arm of the torsion spring 700 is limited to the door panel 800, and the second torsion arm of the torsion spring 700 is limited to the transmission component 200 and rotates with the pivot part 203. The restoring force of the torsion spring 700 is used to drive the door push component 300, the transmission component 200, and the drive component 100 to reset. The structure is simple, the performance is stable, and it is easy to disassemble and assemble.

[0098] 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 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 cavity. A door panel 800 is fixed to the side wall of the drawer body facing away from the cavity. The edge of the door panel 800 abuts against the cabinet body.

[0099] 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.

[0100] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
