Description

Technical Field

[0001] This application relates to the field of locker door opening technology, and more particularly to a locker. Background Technology

[0002] In storage appliances such as refrigerators, beverage cabinets, and display cases, the door is usually hinged to the cabinet body, allowing the door to rotate relative to the cabinet body to open or close the storage space. When users are holding items and their hands are occupied, it is difficult to open the door manually using traditional methods, so foot-operated door opening systems have emerged.

[0003] In related technologies, the foot pedal for opening the door is usually located on the front of the door for easy operation. However, the foot pedal protrudes from the surface of the refrigerator body or door, resulting in a larger overall size of the refrigerator, which in turn affects packaging and transportation. Summary of the Invention

[0004] This application provides a locker to improve the convenience of locker packaging and transportation.

[0005] In a first aspect, embodiments of this application provide a locker, which includes:

[0006] The cabinet is constructed to form a storage compartment with an access opening on the front side;

[0007] A door, one end of which is hinged to the cabinet body along its width, to open or close the storage compartment;

[0008] A foot-operated door opening mechanism is located at the end of the cabinet opposite to the hinge; the foot-operated door opening mechanism includes:

[0009] The base is fixedly connected to the cabinet body;

[0010] A door opening component is connected to the base, and the door opening component is located between the front side of the cabinet and the rear side of the door.

[0011] A foot pedal is rotatably connected to the base; the foot pedal is configured to drive the door opening component to move when subjected to a stepping force, so as to open the door; the foot pedal has a foot surface that can withstand stepping force.

[0012] The foot pedal is located on one side of the cabinet along its width, and has a retracted state and an extended state. In the retracted state, the foot pedal surface faces the side of the cabinet along its width. The foot pedal is configured to rotate relative to the cabinet to switch between the retracted state and the extended state.

[0013] The footrest has a first projection on the side of the cabinet along the width direction in the unfolded state, and a second projection on the side of the cabinet along the width direction in the retracted state, wherein the area of ​​the first projection is smaller than the area of ​​the second projection.

[0014] The storage cabinet in this embodiment features a foot-operated opening mechanism on the side of the cabinet away from the hinge. This mechanism allows for hand-operated opening, freeing up the hands and increasing the variety of opening methods. Compared to manual opening, the foot-operated mechanism, which involves stepping down to open the door, aligns with the body's natural force exertion, making the opening experience more effortless.

[0015] The foot-operated door opening mechanism uses a foot pedal to withstand the force of being stepped on, a door opening mechanism to push open the door, and a base for fixed connection to the cabinet. The base is rotatably connected to both the foot pedal and the door opening mechanism, allowing both to rotate relative to the cabinet.

[0016] Furthermore, the foot pedal, when retracted, faces the side of the cabinet along its width, resulting in a flat overall appearance and minimizing its width, greatly facilitating packaging and transportation. When extended, the foot pedal forms an angle with the side of the cabinet, creating a more comfortable stepping position and enhancing user convenience.

[0017] In addition, the foot pedal is designed to rotate relative to the side of the cabinet and switch between a folded and an unfolded state. In the folded state, the flat foot pedal faces and is close to the side of the cabinet, minimizing the width of the storage cabinet, facilitating packaging and transportation, and reducing packaging materials and costs. In the unfolded state, the flat foot pedal is positioned for easy stepping or operation by the user. When the foot pedal bears the pressure of being stepped on, it rotates forward, driving the door opening mechanism to open the door, improving the convenience of the foot-operated door opening.

[0018] In some embodiments of this application, the foot pedal opening mechanism further includes: a connecting shaft, through which the foot pedal is rotatably connected to the base; the foot pedal is configured to rotate about the central axis of the connecting shaft to switch between the folded state and the unfolded state.

[0019] In this embodiment, the foot-operated door opening mechanism uses a connecting shaft to allow the foot pedal to rotate relative to the base around the central axis of the connecting shaft, thus switching between the folded and unfolded states. The structure is simple and easy to operate.

[0020] In some embodiments of this application, one side of the foot pedal is rotated 90° away from the side of the cabinet to form the unfolded state.

[0021] This design ensures that when the foot pedal is folded up, it is close to the side of the cabinet, minimizing the cabinet's overall size. When the foot pedal is unfolded, the foot surface faces backward, facilitating a comfortable stepping posture and improving ease of use.

[0022] In some embodiments of this application, when the foot pedal is in the retracted state, there is a gap between the foot pedal and the side of the cabinet along the width direction.

[0023] This design prevents the foot pedal from contacting the side of the cabinet when it is folded up, thus avoiding friction against the side of the cabinet and affecting its appearance.

[0024] In some embodiments of this application, the connecting shaft extends vertically perpendicular to the horizontal plane between the folded state, the unfolded state, and between the folded state and the unfolded state.

[0025] With this configuration, the connecting shaft extends parallel to the height of the cabinet, allowing the foot pedal to switch between its extended and retracted states away from the direction of gravity, and thus away from the direction in which the foot pedal bears the force of being stepped on. Therefore, the transition between the extended and retracted states of the foot pedal does not interfere with the movement of the door opening due to the force of being stepped on, ensuring the independent realization of each function.

[0026] In some embodiments of this application, the foot-operated door opening mechanism further includes a hinge shaft;

[0027] The connecting shaft is rotatably connected to the hinge shaft so that the foot pedal can switch between the retracted state and the extended state.

[0028] The hinge shaft is rotatably connected to the base so that the foot pedal rotates about the central axis of the hinge shaft.

[0029] In this embodiment, the connecting shaft is rotatably connected to the hinge shaft, allowing the foot pedal to switch between a retracted and extended state. This simplifies the structure of the foot-operated door opening mechanism, utilizing fewer structural components. It allows the foot pedal to switch between extended and retracted states through rotation, and also enables the foot pedal to rotate under pressure, driving the door opening mechanism to open the door. Furthermore, the connection between the connecting shaft and the hinge shaft facilitates the intersecting of the central axis of the connecting shaft and the central axis of the hinge shaft, thus ensuring that the two rotational directions of the foot pedal are staggered and do not interfere with each other.

[0030] In some embodiments of this application, the hinge shaft is configured to form a first limiting surface, which intersects the axial direction of the hinge shaft; when the foot pedal rotates to abut against the first limiting surface, the foot pedal is in the retracted state.

[0031] By setting a first limiting surface on the hinge shaft to abut against the foot pedal, the retracted state of the foot pedal can be limited, thus preventing the foot pedal from contacting the side of the cabinet along the width direction when it is retracted, which would wear down the appearance surface of the cabinet.

[0032] In some embodiments of this application, the hinge shaft is configured to have a second limiting surface, the second limiting surface being located in front of the first limiting surface, and the second limiting surface intersecting with the first limiting surface;

[0033] When the foot pedal rotates to abut against the second limiting surface, the foot pedal is in the unfolded state.

[0034] By setting a second limiting surface on the hinge shaft, which abuts against the pedal component, the unfolded state of the pedal component is limited, restricting its rotation to the unfolded position and ensuring a stable unfolded position. Furthermore, the contact between the second limiting surface and the second mating surface also limits the forward rotation of the pedal component around the hinge shaft, preventing it from rotating around the connecting shaft while rotating around the hinge shaft, thus contributing to the stability of the pedal component under pedaling force.

[0035] In some embodiments of this application, from the retracted state, when one side of the foot pedal rotates away from the side of the cabinet until the door opening component abuts against the foot pedal, the foot pedal is in the unfolded state.

[0036] In this way, the unfolded state of the foot pedal is limited by the contact limit between the foot pedal and the door opening component; the limit can be achieved by using the side of the door opening component. The structure is simple and easy to implement.

[0037] Secondly, embodiments of this application provide a locker, which includes:

[0038] The cabinet is constructed to form a storage compartment with an access opening on the front side;

[0039] A door, one end of which is hinged to the cabinet body along its width, to open or close the storage compartment;

[0040] A foot-operated door opening mechanism is located at the end of the cabinet opposite to the hinge; the foot-operated door opening mechanism includes:

[0041] The door opening component is connected to the bottom side of the cabinet body, and the door opening component is located between the front side of the cabinet body and the rear side of the door body;

[0042] A foot pedal is rotatably connected to the bottom side of the cabinet and is located on one side of the cabinet along its width. The foot pedal includes a flat foot portion to withstand stepping force. When the foot portion withstands stepping force, the foot pedal drives the door opening component to move and open the door.

[0043] The foot pedal has a folded position and an unfolded position, and the foot pedal is configured to rotate relative to the side of the cabinet to switch between the folded position and the unfolded position.

[0044] When the foot pedal is in the retracted position, the foot surface of the foot pedal faces and is close to the side of the cabinet; when the foot pedal is in the unfolded position, the foot pedal is configured to rotate forward under force and drive the door opening component to move at a preset position.

[0045] The storage cabinet in this embodiment features a foot-operated opening mechanism on the side of the cabinet away from the hinge. This mechanism allows for hand-operated opening, freeing up the hands and increasing the variety of opening methods. Compared to manual opening, the foot-operated mechanism, which involves stepping down to open the door, aligns with the body's natural force exertion, making the opening experience more effortless.

[0046] The foot-operated door opening mechanism uses a foot pedal to withstand the force of being stepped on, a door opening mechanism to push open the door, and a base for fixed connection to the cabinet. The base is rotatably connected to both the foot pedal and the door opening mechanism, allowing both to rotate relative to the cabinet.

[0047] The foot pedal of the foot-operated door opening mechanism is located on one side of the cabinet width. The foot operation space avoids the door opening path, providing ample foot operation space and preventing the possibility of collision with the legs when the door is opened, thus improving the safety of the foot-operated door opening mechanism.

[0048] Furthermore, the foot pedal, when retracted, faces the side of the cabinet along its width, resulting in a flat overall appearance and minimizing its width, greatly facilitating packaging and transportation. When extended, the foot pedal forms an angle with the side of the cabinet, creating a more comfortable stepping position and enhancing user convenience. Attached Figure Description

[0076] It should be noted that the brief descriptions of terms in this application are only for the convenience of understanding the embodiments described below, and are not intended to limit the embodiments of this application. Unless otherwise stated, these terms should be understood in their ordinary and common meaning.

[0077] The terms "first," "second," "third," etc., used in the specification, claims, and accompanying drawings of this application are used to distinguish similar or related objects or entities, and do not necessarily imply a specific order or sequence, unless otherwise specified. It should be understood that such terms are interchangeable where appropriate.

[0078] The terms “comprising” and “having”, and any variations thereof, are intended to cover but not exclude inclusion, for example, a product or device that includes a range of components is not necessarily limited to all of the components that are clearly listed, but may include other components that are not clearly listed or that are inherent to such product or device.

[0079] In conventional refrigerators, display cases, and beverage coolers, the doors typically rotate relative to the cabinet body to open and close. However, when hands are occupied while handling items, or when direct contact with the door needs to be avoided to reduce the spread of bacteria, or for elderly people or those with operational difficulties, foot-operated door opening can free up hands and improve ease of use.

[0080] Among them, electric foot-operated door opening requires the integration of sensors, intelligent triggering, delayed closing, and network control, which is costly and consumes a lot of electricity.

[0081] Mechanical foot-operated door openers require no electricity and are low-cost. In related technologies, the foot pedal of the door opener mechanism is usually located on the front of the door for easy operation. However, there is a problem with the foot pedal; due to its high rigidity, hitting it can cause intense pain and compromise safety.

[0082] To facilitate foot operation, the foot pedal typically protrudes from the equipment's exterior surface, increasing the overall size of the machine. For example, the foot pedal may protrude forward from the front surface of the door. This results in larger packaging, affecting the ease of packaging and transportation.

[0083] Therefore, this application provides a storage cabinet with a foot-operated door opening mechanism to enable foot-operated door opening.

[0084] The foot-operated door opening mechanism includes a foot pedal to withstand stepping force; the opening mechanism is used to push open the door. The foot pedal can be retracted and extended. When retracted, it makes the storage cabinet structure more compact, reducing the increased overall size of the cabinet and thus lowering packaging and transportation costs associated with the foot-operated door opening mechanism. When extended, the foot pedal provides a convenient stepping posture, improving the ease of use of the foot-operated door opening mechanism.

[0085] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0086] First, it should be noted that in this embodiment, the width direction of the cabinet and the door corresponds to... Figure 1The X-axis direction corresponds to the height direction of the cabinet and door. Figure 1 In the Z-axis direction, the depth direction of the cabinet corresponds to Figure 1 The Y-axis direction is defined as follows. When the user is facing the locker, along the X-axis, the side of the locker facing the user is the front side, and the other side is the back side.

[0087] Combination Figure 1 This application provides a storage cabinet for storing items.

[0088] The locker may include a cabinet body 100, which is constructed to form a storage compartment with an access opening on the front side for storing items. The cabinet body 100 may be made of sheet metal, sheet plastic, or composite materials, and has sufficient structural strength and rigidity to support the weight of the stored items.

[0089] Of course, the internal space of cabinet 100 can be divided into multiple compartments or multiple storage areas according to storage needs to provide a diverse storage environment.

[0090] The locker may also include a door 200, which is hinged to the cabinet 100 to open or close the storage compartment.

[0091] like Figure 1 As shown, the door body 200 along the width direction (corresponding to) Figure 1 One end of the door (in the X-axis direction) is hinged to the cabinet 100. For example, the door 200 is hinged to the cabinet 100. In this way, the door 200 can rotate relative to the cabinet 100 to open or close the storage compartment.

[0092] Continue to refer to Figure 1 The locker in this application embodiment may also include a foot-operated door opening mechanism 300, which is located at the end of the locker 100 away from the hinged door 200. The foot-operated door opening mechanism 300 is configured to open the door 200 by bearing the user's stepping force.

[0093] With this configuration, the foot-operated door opening mechanism 300 is located on the side of the door 200 away from the hinge. On the one hand, it allows for the door 200 to be opened with a smaller force; on the other hand, under the premise of the same opening angle, the opening interval at the end away from the hinge of the door 200 is larger, which is convenient for continuing to open the door 200.

[0094] It should be noted that when opening the door 200 using the foot-operated door opening mechanism 300, opening the door 200 to a certain angle, such as 20°, does not mean that the door 200 is opened to its fully open angle. Taking refrigerators as an example, the fully open angle of the door 200 of some refrigerators can be 90° or 100°, etc.

[0095] In this embodiment, the foot-operated door opening mechanism 300 is installed on the cabinet 100. Thus, the foot-operated door opening mechanism 300 does not move with the door 200, and the door can be opened by foot or manually without affecting the opening and closing of the door 200.

[0096] For example, the foot-operated door opening mechanism 300 is connected to the bottom surface of the cabinet 100, so that the installation structure of the foot-operated door opening mechanism 300 can be hidden in the bottom surface of the cabinet 100, thus ensuring the appearance of the storage cabinet.

[0097] Combination Figure 2 The bottom of the refrigerator is usually provided with feet 130 so that the bottom of the cabinet 100 is suspended relative to the placement surface, which facilitates heat dissipation. The part of the foot-operated door opening mechanism 300 located on the bottom of the cabinet 100 does not protrude from the bottom of the feet 130, so as to avoid the foot-operated door opening mechanism 300 from affecting the normal placement of the storage cabinet.

[0098] In some embodiments, the foot-operated door opening mechanism 300 can be installed on the bottom plate of the cabinet 100, reducing the need for modifications to the bottom of the cabinet 100 due to the installation of the foot-operated door opening mechanism 300, which helps to reduce costs.

[0099] The storage cabinet in this application embodiment can be a simple storage cabinet, such as a clothes cabinet; or, the storage cabinet can also be a device that can adjust the storage state, such as a refrigerator, a preservation cabinet, a vertical freezer, a display cabinet, etc.; or, the storage cabinet can also be a clothing treatment device that can remove odors from clothes. This application embodiment does not limit the functions of the storage cabinet other than the storage function.

[0100] However, it should be noted that the storage cabinet in this embodiment has a single-sided door. This means that the storage compartment can be closed and opened along the width of the cabinet 100 using a single door 200. Figure 1 As shown. This does not mean that the locker has a door 200.

[0101] For example, cabinet 100 defines a plurality of [facilities] along the height direction (corresponding to [facilities]). Figure 1 Storage compartments are arranged side-by-side along the Z-axis, with each compartment having a corresponding door 200. For example, some refrigerators include a refrigerator compartment and a freezer compartment arranged side-by-side along the height, with each compartment having a door 200.

[0102] When multiple doors 200 are provided along the height of the cabinet 100, the foot-operated door opening mechanism 300 of this embodiment is configured to open the bottommost door 200. Of course, the cabinet can also be configured with a longer transmission mechanism to open the upper doors 200 by foot.

[0103] like Figure 1 As shown, some refrigerators have a large storage compartment and a heavy metal door 200. When a foot-operated door opening mechanism 300 is included, it frees up the hands, allowing for easy handling of items. Furthermore, compared to hand-operated opening, the downward force applied by the foot incorporates part of the body's weight, conforming to the natural movement of a standing person without shifting the body's center of gravity, making opening the door more convenient.

[0104] Reference Figure 2 The foot-operated door opening mechanism 300 of this application embodiment may include a door opening member 310, which is located between the front side 110 of the cabinet 100 and the rear side 210 of the door 200. The door opening member 310 is configured to abut against the rear side 210 of the door 200 to push the door 200 forward.

[0105] The door opening component 310 has a gap between it and the front side 110 of the cabinet 100 to prevent contact and friction between the door opening component 310 and the front side 110, which would affect the appearance of the cabinet 100.

[0106] When the door opening component 310 is not in the open state, there is a gap between the rear side 210 of the door body 200 and the door opening component 310, so as to avoid contact and friction between the door opening component 310 and the rear side 210, which would affect the appearance of the door body 200.

[0107] In this embodiment, the door opening component 310 is connected to the cabinet 100, and the door opening component 310 is configured to rotate relative to the cabinet 100 to open the door 200. The door opening component 310 is rotatably connected to the bottom side of the cabinet 100, so that the door opening component 310 can rotate relative to the cabinet 100.

[0108] The door opening component 310 can be directly connected to the cabinet body 100 via a hinge structure, allowing the door opening component 310 to rotate relative to the cabinet body 100. Alternatively, the door opening component 310 can be rotatably connected to an intermediate component, while the rotating component is fixedly connected to the cabinet body 100, allowing the door opening component 310 to be indirectly connected to the cabinet body 100.

[0109] like Figure 2 As shown, the foot-operated door opening mechanism 300 may further include a base 330, which is fixedly connected to the cabinet 100. The door opening component 310 is rotatably connected to the base 330, allowing the door opening component 310 to rotate relative to the cabinet 100. This configuration allows the base 330 to be fixed to the cabinet 100, thus completing the installation of the foot-operated door opening mechanism 300. This simplifies the installation process and improves assembly efficiency.

[0110] Continue to refer to Figure 2A door seal 220 is typically provided on the rear side 210 of the door 200 facing the cabinet 100. The door seal 220 contacts the front side 110 of the cabinet 100 to improve the airtightness of the door 200 when closing the storage compartment. The door opening component 310 is located outside the door seal 220.

[0111] Along the width direction of the door body 200, there is a gap between the door opening component 310 and the door seal 220, which can prevent the door opening component 310 from contacting the door seal 220 and rubbing against the door seal 220.

[0112] In some embodiments, along the depth direction of the cabinet 100 (corresponding to...) Figure 2 (In the Y-axis direction), there is a gap between the door opening component 310 and the rear side 210 of the door body 200, and a gap between the door opening component 310 and the front side 110 of the cabinet body 100. Thus, there is sufficient space between the rear side 210 and the front side 110 of the door body 200 to install the door opening component 310, reducing the possibility of the door opening component 310 colliding with the door body 200 or the cabinet body 100 during installation.

[0113] Continue to refer to Figure 2 The cabinet body 100 has two opposing sides along its width. The side facing away from the hinged side of the door body 200 is defined as the first side 120. The door body 200 also has two opposing sides along its width. The side facing away from the hinged side of the door body 200 is defined as the second side 230. The first side 120 can be flush with the second side 230, giving the cabinet a more regular shape and contributing to a compact size, facilitating packaging and transportation.

[0114] In some possible implementations, the side of the door opening component 310 facing away from the door seal 220 can protrude from the second side 230 along the width direction of the cabinet 100, so that the door opening component 310 has a large size along the width direction, which helps to ensure sufficient structural strength and rigidity.

[0115] In some other possible implementations, along the width of the cabinet 100, the side of the door opening component 310 that is away from the door seal 220 may not protrude from the second side 230. This helps to improve the structural compactness of the foot-operated door opening mechanism 300 and also helps to hide the door opening component 310, making the storage cabinet more regular.

[0116] In some embodiments, such as Figure 2 As shown, the top of the door opener 310 is used to abut against the door body 200 to open the door body 200. The top of the door opener 310 can protrude from the second side 230, which helps to ensure structural strength. The bottom of the door opener 310 serves a connecting function, and its side away from the door seal 220 can be flush with the second side 230, ensuring structural compactness while concealing part of the structure of the door opener 310.

[0117] Continue to refer to Figure 2 The foot-operated door opening mechanism 300 in this embodiment may also include a foot pedal 320, which is used to bear the stepping force and drive the door opening component 310 to move, thereby opening the door 200.

[0118] The foot pedal 320 can be located on the side of the cabinet 100 along its width and away from the hinge, such as... Figure 2 As shown, the foot pedal 320 is located on one side of the first side 120. With this configuration, the user applies stepping force on one side of the cabinet 100 along the width direction, providing ample operating space. Furthermore, it avoids the forward opening path of the door 200, thereby preventing the door 200 from colliding with the leg when stepping to open the door, thus helping to improve the safety of foot-operated door opening.

[0119] In this embodiment, the foot pedal 320 is connected to the cabinet 100, and all foot pedals 320 are configured to rotate relative to the cabinet 100. The foot pedal 320 is rotatably connected to the bottom side of the cabinet 100, allowing the foot pedal 320 to rotate relative to the cabinet 100.

[0120] The foot pedal 320 can be directly connected to the cabinet 100 via a hinge structure, allowing the foot pedal 320 to rotate relative to the cabinet 100. Alternatively, the foot pedal 320 can be rotatably connected to an intermediate component, while the rotating component is fixedly connected to the cabinet 100, thus indirectly connecting the foot pedal 320 to the cabinet 100.

[0121] like Figure 2 As shown, the foot pedal 320 is rotatably connected to the base 330, allowing the foot pedal 320 to rotate relative to the base 330. With this configuration, both the foot pedal 320 and the door opening mechanism 310 are connected to the cabinet 100 via the base 330. The foot-operated door opening mechanism 300 forms a modular structure; after fixing the base 330 to the cabinet 100, the entire mechanism can be installed, simplifying the assembly process of the storage cabinet and improving assembly efficiency.

[0122] The foot pedal 320 is located on one side of the cabinet 100 along the width direction, which facilitates providing a larger operating space and also allows the foot pedal 320 to avoid the opening path of the door 200, reducing the possibility of collision between the foot pedal 320 and the legs when the door 200 is opened.

[0123] Continue to refer to Figure 2 In some embodiments, the base 330 is fixedly connected to the base plate of the cabinet 100 by screws, and the connection method is reliable and stable.

[0124] For example, the base 330 is fixedly connected to the base plate of the cabinet 100 by multiple screws. For instance, the base 330 is fixedly connected to the base plate of the cabinet 100 by three screws arranged in a triangle, which helps to improve the reliability of the installation of the base 330.

[0125] Of course, the base 330 can also be fixedly connected to the cabinet 100 in other ways. For example, the base 330 can be fixedly connected to the cabinet 100 by snap-fit ​​and screw connection. Alternatively, the base 330 can be fixedly connected to the cabinet 100 by welding or gluing.

[0126] Moreover, the fixing structure between the base 330 and the cabinet 100 hides the bottom surface of the cabinet 100, allowing the base 330 to reuse the space between the bottom surface of the cabinet 100 and the feet 130, eliminating the need for additional installation space and helping to improve the overall structural compactness of the storage cabinet.

[0127] In some embodiments, the base 330 can fix the first side 120 of the cabinet 100 along the width direction, with ample installation space.

[0128] Combination Figure 3 In this embodiment, the foot-operated door opening mechanism 300 may further include a hinge shaft 340, the base 330 is rotatably connected to the foot pedal 320 via the hinge shaft 340, and the base 330 is rotatably connected to the door opening component 310 via the hinge shaft 340.

[0129] The hinge shaft 340 can be made of metal materials such as carbon steel, stainless steel or alloy steel, and has sufficient structural strength and rigidity.

[0130] Thus, the foot pedal 320 and the door opening component 310 are rotatably connected to the base 330 via the same hinge shaft 340. The stepping force of the foot pedal 320 is transmitted to the door opening component 310 through the hinge shaft 340. The force transmission path is simple, which helps to simplify the structure of the foot pedal door opening mechanism 300. Moreover, this allows the rotation angle of the foot pedal 320 to be the same as the rotation angle of the door opening component 310, which helps to open the door body 200 by a larger angle, facilitating subsequent manual opening.

[0131] like Figure 2 and Figure 3 As shown, the hinge shaft 340 extends along the width of the cabinet 100, allowing the foot pedal 320 and the door opening component 310 to rotate forward relative to the cabinet 100 to open the door 200. The foot pedal 320 can also rotate backward independently of the door opening component 310, causing the foot pedal 320 to retract backward.

[0132] Of course, in practical applications, the hinge shaft 340 can be tilted slightly relative to the width of the cabinet 100 to adapt to the actual application scenarios, installation and processing errors of the storage cabinet, as long as the foot pedal 320 and the door opening part 310 can rotate relative to the cabinet 100 toward the door 200 to open the door 200.

[0133] In some other possible implementations, the hinge shaft 340 may extend along the depth direction of the cabinet 100, or be slightly inclined at a certain angle relative to the depth direction of the cabinet 100. The foot pedal 320 is located on one side of the cabinet 100 along its width direction. The foot pedal 320 rotates downwards, and through a transmission structure between the foot pedal 320 and the door opening member 310, or a transmission structure provided with the door opening member 310, it drives the door opening member 310 to open the door 200. The foot pedal 320 may also rotate upwards independently of the door opening member 310, providing a buffer space for the foot pedal 320 to withstand impact forces.

[0134] Continue to refer to Figure 3 In some embodiments of this application, the foot-operated door opening mechanism 300 further includes an elastic element 360, which is elastically connected between the base 330 and the door opening member 310. When the door opening member 310 pushes open the door body 200, the elastic element 360 undergoes elastic deformation, accumulating elastic force for the reset of the foot pedal member 320 and the door opening member 310. When the foot pedal member 320 loses its pedaling force, the elastic element 360 restores its deformation, thereby driving the door opening member 310 and the foot pedal member 320 to reset.

[0135] In this embodiment, an elastic element 360 provides a reset force to the door opening component 310 and the foot pedal component 320, allowing them to reset after opening without affecting the closing of the door 200. Furthermore, the foot pedal component 320 resets after each opening, ensuring consistent foot placement and a clear starting point for opening the door. This facilitates muscle memory development, eliminating the need for visual confirmation of the foot position and enabling blind operation, thus improving the convenience of opening the door by foot.

[0136] Continue to refer to Figure 3 In some embodiments of this application, a roller 311 is rotatably mounted on the top of the door opening member 310. When the door opening member 310 pushes open the door body 200, the roller 311 is configured to roll into contact with the rear side 210 of the door body 200.

[0137] When the foot pedal 320 is not subjected to stepping force, the door opening component 310 does not push open the door body 200. There can be a gap between the roller 311 and the rear side 210 of the door body 200. On the one hand, during installation, the door opening component 310 can be quickly inserted between the rear side 210 of the door body 200 and the front side 110 of the cabinet 100 to improve installation efficiency. On the other hand, it can prevent the door body 200 from contacting the roller 311 and wearing down the door body 200 when manually closing the door, which helps to maintain the appearance of the door body 200.

[0138] With this configuration, during the process of opening the door body 200, the roller 311 rolls into contact with the rear side 210 of the door body 200, which helps to reduce friction and reduce the friction of the door opening component 310 on the door body 200, thereby helping to reduce the friction noise of the door opening component 310 during the process of opening the door body 200.

[0139] In some possible implementations, the top of the door opening component 310 may be provided with a contact buffer. The contact buffer may be made of an elastic material, such as rubber, silicone, or polyurethane. The contact buffer contacts the rear side 210 of the door body 200, which can both open the door body 200 and reduce the impact force and noise generated during the opening process, and also protect the surface of the rear side 210 of the door body 200.

[0140] The elastic material of the contact cushioning portion can have different hardness and elastic modulus. Softer elastic materials provide better cushioning but have poorer abrasion resistance. Harder elastic materials have better abrasion resistance but limited cushioning effect. In some embodiments, the contact cushioning portion uses a rubber material with a hardness of Shore A50 to Shore A70. This hardness range ensures both sufficient cushioning performance and good durability.

[0141] In a foot-operated door, the projection of the foot pedal 320 onto the horizontal plane protrudes beyond the projections of the cabinet 100 and the door 200 onto the horizontal plane, providing convenience for the foot pedal 320 to withstand stepping forces. For example, the projection of the foot pedal 320 onto the horizontal plane protrudes beyond the front surface of the door 200; another example is that the projection of the foot pedal 320 onto the horizontal plane protrudes beyond the side of the cabinet 100 along its width.

[0142] However, this also leads to a larger overall size of the locker, resulting in larger packaging and thus increased packaging and transportation costs. Specifically, the overall size of the locker is determined by its length along the sides. Figure 1 The maximum dimensions in the XYZ directions.

[0143] For example, when the foot pedal 320 protrudes forward from the front surface of the door 200, the maximum dimension of the whole machine along the Y-axis changes from the distance between the rear surface of the cabinet 100 and the front surface of the door 200 to the distance between the rear surface of the cabinet 100 and the front end of the foot pedal 320. The irregular shape leads to an increase in packaging material.

[0144] Therefore, the foot pedal opening mechanism 300 provided in this application embodiment has a foot pedal 320 that can be folded up, making the overall structure of the locker compact, reducing the increased external dimensions due to the foot pedal opening mechanism 300, and thus reducing the increased packaging and transportation costs due to the foot pedal opening mechanism 300.

[0145] In some of the above embodiments, the foot pedal 320 and the door opening member 310 rotate relative to the bottom side of the cabinet 100. The foot pedal 320 is configured to drive the door opening member 310 to rotate in a first direction when subjected to a stepping force, so that the door opening member 310 pushes open the door 200. The foot pedal 320 is also configured to rotate independently relative to the door opening member 310 in a second direction, wherein the second direction is opposite to the first direction. In this way, the foot pedal 320 can rotate in the second direction, so that the foot pedal 320 retracts relative to the stepping position, which reduces the impact of the foot pedal 320 and improves safety, while also helping to retract the foot pedal door opening mechanism 300.

[0146] In some embodiments, the door opening component 310 and the foot pedal component 320 are respectively connected to the bottom side of the cabinet 100. The door opening component 310 and the foot pedal component 320 are respectively connected to the base 330, thereby installing the door opening component 310 and the foot pedal component 320 to the cabinet 100. The foot pedal component 320 is configured to drive the door opening component 310 to move when stepped on, thereby opening the door 200.

[0147] For example, the foot pedal 320 and the door opening member 310 rotate relative to the base 330, so that when the foot pedal 320 rotates under the force of being stepped on, it drives the door opening member 310 to rotate, so that the door opening member 310 pushes open the door body 200.

[0148] For example, the foot pedal 320 is configured to move relative to the base 330 when subjected to a stepping force, or a combination of movement and rotation, thereby causing the door opening member 310 to move relative to the base 330, or a combination of movement and rotation, so that the door opening member 310 pushes open the door body 200.

[0149] Combination Figure 2 The foot pedal 320 is located on one side of the cabinet 100 along its width, and the foot pedal 320 has a retracted state. Combined with... Figure 4 When the foot pedal 320 is in the retracted state, the foot pedal surface 3211 faces the side of the cabinet 100 along its width. Figure 4 In the middle, when the foot pedal 320 is in the folded state, the foot pedal surface 3211 approaches and faces the first side 120.

[0150] Combination Figure 5 The foot pedal 320 has an unfolded state. The foot pedal 320 is configured to rotate relative to the cabinet 100 to switch between a folded state and an unfolded state. One side of the foot pedal 320 rotates away from the side of the cabinet 100 to form the unfolded state. In the folded state, the rear side of the foot pedal 320 rotates away from the first side 120 to form the unfolded state. Exemplarily, in the unfolded state, the foot pedal surface 3211 faces the rear side of the cabinet 100.

[0151] In this embodiment, the footrest 3211 has a first projection onto the side of the cabinet 100 along the width direction when in the unfolded state, and a second projection onto the side of the cabinet 100 along the width direction when in the folded state. The area of ​​the first projection is smaller than the area of ​​the second projection. In the folded state, the footrest 3211 faces the first side 120, and the second projection area of ​​the footrest 3211 on the first side 120 is larger. The footrest 320 is configured to rotate relative to the cabinet 100 and rotate from the folded state to the unfolded state, such that the first projection area of ​​the footrest 3211 facing the first side 120 in the unfolded state is smaller than the area of ​​the second projection.

[0152] Compared to its unfolded state, the foot pedal 320 results in a smaller projected area of ​​the entire locker in the horizontal plane when folded, facilitating packaging and transportation. The projected area is the product of the maximum length and maximum width of the area projected in the horizontal plane. For example... Figure 6 As shown, in the unfolded state, the foot pedal 320 extends to the cabinet 100, resulting in a large volume and thus a large external dimension of the storage cabinet in the width direction. Therefore, in the unfolded state, the storage cabinet has a large external volume.

[0153] In its retracted state, the foot pedal 320 fits against the side of the cabinet 100 along its width, compared to its unfolded state. This "fitting" does not mean that the foot pedal 320 contacts the side of the cabinet 100, but rather that the retracted state results in a smaller increase in the overall size of the storage cabinet compared to its unfolded state.

[0154] Combination Figure 4 In the folded state, the middle surface M of the foot pedal 320 can be parallel to the first side surface 120 of the cabinet 100, so that the foot pedal 320 protrudes a small volume relative to the outer surface of the cabinet 100 to present a folded state, which facilitates packaging and transportation. Of course, this is not a limitation on the folded state. For example, in the folded state, the middle surface M of the foot pedal 320 is tilted at a small angle relative to the first side surface 120, such as 1°.

[0155] For ease of explanation, the foot pedal 320 is defined to have a middle surface M. The middle surface M passes through the middle position of the foot pedal 320 and through the axis of rotation of the foot pedal 320 relative to the base 330.

[0156] like Figure 3As shown, the foot pedal 320 includes a foot pedal portion 321, which has a foot surface 3211 for bearing the force of stepping. The foot pedal portion 321 can be a solid structure with good structural strength; alternatively, it can be a hollow structure, for example, by forming multiple hollow holes in the foot pedal portion 321. This ensures a large stepping area while making the foot pedal portion 321 lightweight and saving materials.

[0157] The surface treatment of the footrest 3211 can be an anti-slip texture, a rubber coating, or a frosted finish. An anti-slip texture is created by machining an embossed pattern to increase surface friction. A rubber coating achieves its anti-slip function by spraying or applying rubber material. A frosted finish increases the coefficient of friction by roughening the surface. In some embodiments, the footrest 3211 uses a diamond-shaped anti-slip texture with a texture depth of 0.5 mm to 1.0 mm.

[0158] When in the pedaling position, the footrest surface 3211 is located above the middle surface M. The footrest surface 3211 can be a flat surface, with a simple structure and easy manufacturing; or, the footrest surface 3211 can be a curved surface, such as an arc surface, which can form both the pedaling area and a smooth edge for easy pedaling. When the footrest 321 has a regular symmetrical shape, for example... Figures 5 to 7 The ellipse shown has its middle surface M coinciding with the symmetrical plane of the foot pedal 321.

[0159] like Figure 7 As shown, the foot pedal 320 may also include a connecting portion 322, which is connected to the hinge shaft 340. When the connecting portion 322 is cylindrical, the middle surface M passes through the central axis of the connecting portion 322.

[0160] In some embodiments, the pedal 320 is rotatably connected to the hinge shaft 340 via a connecting shaft 350, allowing the pedal 320 to rotate relative to the hinge shaft 340. The pedal 320 is defined to rotate about a second central axis O2 relative to the hinge shaft 340. The second central axis O2 can be the central axis of the connecting shaft 350. The intermediate surface M passes through the second central axis O2.

[0161] Continue to refer to Figure 3 In this embodiment of the application, the foot pedal opening mechanism 300 further includes: a connecting shaft 350, and the foot pedal 320 is rotatably connected to the base 330 through the connecting shaft 350; the foot pedal 320 is configured to rotate about the central axis of the connecting shaft 350 to switch between a folded state and an unfolded state.

[0162] Among them, the centerline of the connecting shaft 350 is defined as the second centerline O2.

[0163] In some embodiments, such as Figure 4 , Figure 6 as well as Figure 7 As shown, in the folded state, the unfolded state, and between the folded and unfolded states, the connecting shaft 350 extends vertically perpendicular to the horizontal plane.

[0164] With this configuration, the connecting shaft 350 extends parallel to the height of the cabinet 100, allowing the foot pedal 320 to switch between its extended and retracted positions away from the direction of gravity, and thus away from the direction in which the foot pedal 320 bears the force of being stepped on. Therefore, the transition between the extended and retracted positions of the foot pedal 320 does not interfere with the movement of the door opening due to the force of being stepped on, ensuring the independent realization of their respective functions.

[0165] In other embodiments, the connecting shaft 350 may extend along the depth direction of the cabinet 100. Thus, the foot pedal 320 rotates downwards from one side of the first side panel 120 from the folded position to the unfolded position. In the unfolded position, the flat foot pedal portion 321 may be in a horizontal state.

[0166] In some other embodiments, the connecting shaft 350 may extend along the width of the cabinet 100, in which case the foot pedal 320 may be located on the front side of the door 200. During packaging and transportation, the foot pedal 320 flips upward to approach the front surface of the door 200, presenting a folded state; in the use state, the foot pedal 320 flips downward to present an unfolded state.

[0167] Therefore, in this embodiment of the application, the foot pedal opening mechanism 300, by setting a connecting shaft 350, allows the foot pedal 320 to rotate relative to the base 330 around the central axis of the connecting shaft 350, thereby achieving the switching between the folded state and the unfolded state. The structure is simple and easy to operate.

[0168] Continue to refer to Figure 4 When the foot pedal 320 is in the retracted state, there is a gap between the foot pedal 320 and the side of the cabinet 100 along the width direction. That is, there is a gap between the foot pedal 320 and the first side 120. This arrangement can prevent the foot pedal 320 from contacting the side of the cabinet 100 in the retracted state and rubbing against the side of the cabinet 100, thus affecting the appearance of the storage cabinet.

[0169] like Figure 6 As shown, in the unfolded state, the middle surface M of the foot pedal 320 intersects with the first side surface 120 of the cabinet 100 at a certain angle. For example, the middle surface M is perpendicular to the first side surface 120 of the cabinet 100, so that the foot pedal 320 protrudes a large volume relative to the outer surface of the cabinet 100, which facilitates stepping operation.

[0170] In this embodiment, the foot pedal portion 321 of the foot pedal 320 can be flat to facilitate the formation of a larger foot surface 3211 to withstand the pedaling force. For example... Figure 4 As shown, when the foot pedal 320 is in the folded state, its flat foot pedal portion 321 is close to the first side 120 with a larger foot pedal surface 3211. In this way, the foot pedal 320 increases the dimension of the foot pedal portion 321 in the thickness direction relative to the outer surface of the cabinet 100. However, the dimension of the foot pedal portion 321 in the thickness direction is smaller than the length and width of the foot pedal surface 3211, resulting in a smaller increase in the overall size of the storage cabinet.

[0171] like Figure 5 As shown, when the foot pedal 320 is in the unfolded state, the foot pedal surface 3211 of its flat foot pedal 320 forms an angle with the first side surface 120, so that the foot pedal surface 3211 faces the front or the back, presenting a posture that is convenient for stepping.

[0172] In this embodiment, the foot pedal 320 has a folded position and an unfolded position, and the foot pedal 320 is configured to rotate relative to the side of the cabinet 100 to switch between the folded position and the unfolded position.

[0173] When the foot pedal 320 rotates to the retracted position relative to the first side 120 of the cabinet 100, the foot pedal 320 is in the retracted state, such as... Figure 4 As shown.

[0174] When the foot pedal 320 rotates to the unfolded position relative to the first side 120 of the cabinet 100, the foot pedal 320 is in the unfolded state, such as... Figure 5 and Figure 6 As shown, the unfolded position of the foot pedal 320 is one of the positions in which the foot pedal 320 is cushioned by an accidental impact force.

[0175] When the foot pedal 320 is in the retracted position, the foot surface 3211 of the foot pedal part 321 faces and approaches the side of the cabinet 100; when the foot pedal 320 is in the extended position, the foot pedal part 321 is configured to rotate forward under force and drive the door opening part 310 to move in a preset position to open the door 200.

[0176] In some embodiments, the foot pedal 321 can drive the door opening member 310 to move when it is in the unfolded position, thereby opening the door 200. In this way, the foot pedal 321 has sufficient rotation space, ensuring that the door 200 can have a large opening angle.

[0177] In other embodiments, the preset position is a certain position where the foot pedal 321 rotates forward, for example, Figure 5 The illustrated stepping state means that after the foot pedal 321 rotates independently forward at a certain angle, it drives the door opening component 310 to move, allowing the door opening component 310 to push open the door body 200. In this way, the foot pedal 321 is positioned at a convenient stepping angle, improving the ease of opening the door by stepping.

[0178] The force that drives the foot pedal 321 to rotate forward independently can be a pedaling force or a manual operating force. When the foot pedal 321 is subjected to a pedaling force, it rotates, thereby driving the door opening component 310 to move.

[0179] With the above settings, in the storage cabinet of this application embodiment, the foot pedal 320 of the foot pedal opening mechanism 300 is located on one side of the width direction of the cabinet body 100, and the foot pedal operation space avoids the opening path of the door body 200, so that the foot pedal operation space is sufficient, and the possibility of collision between the door body 200 and the legs can be avoided when the door body 200 is opened, which helps to improve the safety of the foot pedal opening mechanism 300.

[0180] Furthermore, by retracting the foot pedal 320, the foot surface 3211 of the foot pedal 320 faces the side of the cabinet 100 along its width, resulting in a flat overall appearance and minimizing the width dimension, greatly facilitating packaging and transportation. By extending the foot pedal 320, the foot surface 3211 forms an angle with the side of the cabinet 100, thus facilitating stepping and providing convenience for the user.

[0181] Furthermore, the foot pedal 320 is configured to rotate relative to the side of the cabinet 100 and switch between a folded position and an unfolded position. In the folded position, the flat foot pedal 321's foot surface 3211 faces and approaches the side of the cabinet 100, minimizing the width of the storage cabinet, facilitating packaging and transportation, and reducing packaging materials and costs. In the unfolded position, the flat foot pedal 321's foot surface 3211 is positioned for easy stepping or operation by the user. When the foot surface 3211 bears the stepping force, the foot pedal 320 rotates forward, driving the door opening component 310 to move and open the door 200, improving the convenience of the foot-operated door opening.

[0182] Reference Figure 4 and Figure 6 The foot pedal 320 rotates 90° away from the side of the cabinet 100 to form an unfolded state.

[0183] This design ensures that when the foot pedal 320 is folded up, it is close to the side of the cabinet 100, minimizing the overall size of the storage cabinet. It also allows the foot pedal 3211 to face backward when the foot pedal 320 is unfolded, facilitating a comfortable stepping posture and improving the ease of operation.

[0184] Combination Figure 3 In this embodiment, the connecting shaft 350 is rotatably connected to the hinge shaft 340, so that the foot pedal 320 can switch between a retracted state and an extended state. The hinge shaft 340 is rotatably connected to the base 330, so that the foot pedal 320 can rotate about the central axis of the hinge shaft 340.

[0185] For example, such as Figure 3 The hinge shaft 340 is provided with a connecting hole, and the end of the connecting part 322 of the foot pedal 320 forms a connecting shaft 350. The connecting shaft 350 is rotatably installed in the connecting hole, so that the foot pedal 320 can rotate around the central axis of the connecting shaft 350.

[0186] For example, such as Figure 8 As shown, the connecting shaft 350 is fixed on the hinge shaft 340, and the connecting part 322 of the foot pedal 320 forms a bushing structure. The bushing structure is sleeved on the outside of the connecting shaft 350 and rotates relative to the connecting shaft 350.

[0187] In this embodiment, the connecting shaft 350 is rotatably connected to the hinge shaft 340, allowing the foot pedal 320 to switch between a retracted and an extended position. This simplifies the structure of the foot-operated door opening mechanism 300. With fewer structural components, the foot pedal 320 can switch between extended and retracted states by rotation, and the foot pedal 320, under the force of being stepped on, can rotate to drive the door opening component 310 to open the door 200. Furthermore, the connection between the connecting shaft 350 and the hinge shaft 340 facilitates the intersecting of the central axis of the connecting shaft 350 and the central axis of the hinge shaft 340, thereby ensuring that the two rotational directions of the foot pedal 320 are staggered and do not interfere with each other.

[0188] In some embodiments, when the pedal 320 rotates to the unfolded position and rotates around the hinge axis 340, a first limiting structure is provided between the hinge axis 340 and the pedal 320 to restrict the pedal 320 from rotating around the hinge axis 340, ensuring that the pedal 320 does not rotate around the connecting axis 350 during forward rotation, which facilitates the application of force to the pedal 320.

[0189] In some embodiments, a second limiting structure is also provided between the foot pedal 320 and the hinge shaft 340 to limit the foot pedal 320 to the folded position, ensuring that there is a gap between the foot pedal 320 and the first side 120, thereby preventing the foot pedal 320 from contacting the first side 120 and affecting the appearance of the cabinet 100.

[0190] Reference Figure 9 The foot pedal 320 is configured to rotate the door opening member 310 in a first direction when subjected to a stepping force, so that the door opening member 310 pushes open the door body 200. The stepping force is downward, i.e., towards the placement surface of the storage cabinet. The foot pedal 320 is also configured to rotate independently of the door opening member 310 in a second direction; wherein the second direction is opposite to the first direction. Figure 9 In the diagram, the first direction corresponds to the S direction, and the second direction corresponds to the N direction.

[0191] The foot pedal 320 is configured to drive the door opening component 310 to rotate forward when subjected to a stepping force. This not only allows the rotation direction of the door opening component 310 to be in line with the opening direction of the door body 200, which simplifies the transmission components between the stepping force and the opening force, but also makes the stepping direction of the foot pedal 320 conform to the daily operating habits of the human body, making the operation more convenient.

[0192] In some possible implementations of this application, the foot pedal 320 is located on one side of the cabinet 100 along its width. The foot pedal 320 has a step-down position and an unfolded position; the foot pedal 320 is configured to rotate independently relative to the door opening member 310 between the step-down position and the unfolded position.

[0193] Reference Figure 10 When the foot pedal 320 is in the step position, the foot pedal 320 is inclined upward relative to the horizontal plane. Moreover, when in the step position, the foot pedal 320 abuts against the door opening member 310, so that the foot pedal 320 drives the door opening member 310 to rotate in the first direction.

[0194] Reference Figure 7 The foot pedal 320 is in the unfolded position. The foot pedal 320 is configured to rotate from the pedal position to the unfolded position in the second direction.

[0195] When the foot pedal 320 is in the unfolded position, it is perpendicular to the horizontal plane. This design allows the foot pedal 320 to have a larger buffer space and keeps it in a vertical position, reducing the possibility of it being hit by a collision.

[0196] When the foot pedal 320 is subjected to a stepping force, it causes the door opening component 310 to rotate away from the unfolded position, so that the door opening component 310 pushes open the door body 200. It can be understood that when the foot pedal 320 is in the stepping position, it is the stepping position of the foot pedal 320.

[0197] When the foot pedal 320 is in the stepped position, it is tilted upwards relative to the horizontal plane. This can be understood as follows: the horizontal plane passes through the axis of rotation of the foot pedal 320 relative to the cabinet 100, such as the central axis of the hinge shaft 340. When the foot pedal 320 is in the stepped position, its bottom surface is higher than the horizontal plane.

[0198] This design allows the foot pedal 320 ample space to be stepped down, improving the operability of the foot pedal for opening the door and enhancing the user experience. Furthermore, the foot pedal 320 has ample downward rotation space, ensuring that the door 200 has sufficient opening intervals and angles, providing convenience for subsequent door opening.

[0199] For example, using the foot pedal 320 to open the door allows the door 200 to open relative to the cabinet 100 by a preset distance, which allows a hand to be inserted. This provides operating space for the hand to continue opening the door, thereby improving the convenience of opening the door.

[0200] The foot pedal 320 is configured such that, when subjected to a stepping force, it drives the door opening component 310 to rotate in a first direction, causing the door opening component 310 to push open the door body 200, thus realizing the function of foot-operated door opening. Furthermore, the foot pedal 320 is also configured to rotate independently in the opposite direction to the first direction relative to the door opening component 310. This allows the foot pedal 320 to rotate independently in the direction away from the door when subjected to unexpected forces, such as accidental collisions, converting at least a portion of the unexpected force into rotational kinetic energy. This avoids rigid collisions between the foot pedal 320 and the user, reduces the impact force directly transmitted to the user's legs, thereby reducing the pain experienced by the user when colliding with the foot pedal 320 and improving the safety of the foot-operated door opening mechanism 300.

[0201] Therefore, the foot pedal 320 is configured to rotate independently of the door opening mechanism 310 in the second direction, providing a buffer space for the foot pedal 320. When a user accidentally bumps into the foot pedal 320, the foot pedal 320 can rotate towards its buffer space, avoiding a rigid impact and reducing the possibility of damage to the foot pedal 320 due to accidental collisions, thus ensuring the lifespan of the foot pedal 320. Simultaneously, it also prevents damage to items such as sweeping devices caused by collisions with the foot pedal 320, improving the user-friendliness of the foot-operated door opening mechanism 300 and reducing the risk of obstruction and harm to other intelligent entities in the application environment.

[0202] Furthermore, the foot pedal 320 is configured to rotate independently in the second direction, allowing the foot pedal 320 to be in a folded posture, further reducing the possibility of the foot pedal 320 colliding with the user when not in a stepped state, and further improving the safety of the foot pedal door opening mechanism 300.

[0203] The following is combined with Figure 3 and Figure 8 The specific structure and limiting of the foot-operated door opening mechanism 300 are described in detail in some embodiments.

[0204] Reference Figure 8 The door opening component 310 includes a rod portion 312, the top end of which is configured to form two spaced-apart first mounting walls 3121, each of which has a shaft hole. The axle 3111 of the roller 311 is fixed in the shaft holes of the two first mounting walls 3121, and the roller 311 is rotatably mounted on the axle 3111, with the roller 311 located between the two first mounting walls 3121.

[0205] The wheel surface of the roller 311 protrudes from the front surface of the rod 312, so that the wheel surface of the roller 311 can contact the rear side 210 of the door 200 to open the door 200.

[0206] Continue to refer to Figure 8 The door opening component 310 can also be connected to a connecting wall 313, which is curved, and its top end is fixedly connected to the bottom end of the rod portion 312. The extension direction of the connecting wall 313 can be perpendicular to the extension direction of the rod portion 312. Furthermore, to improve the structural strength of the door opening component 310, reinforcing ribs can be provided between the connecting wall 313 and the rod portion 312.

[0207] The rear side 210 of the connecting wall 313 is configured to form a first arcuate surface to match the shape of the hinge shaft 340 and avoid interference.

[0208] like Figure 8 As shown, the door opening component 310 may further include two second mounting walls 314, which are spaced apart along the length of the connecting wall 313. The two second mounting walls 314 are fixedly connected to the rear side of the connecting wall 313. Each of the two second mounting walls 314 is provided with a first hinge hole 3141 for passing through a hinge shaft 340.

[0209] like Figure 8 As shown, the door opening component 310 may also include a first limiting part 315, which is connected to the end of the connecting wall 313. Along the axial direction of the first hinge hole 3141, two second mounting walls 314 are located on one side of the rod body 312, and the first limiting part 315 is located on the other side of the rod body 312.

[0210] The first limiting part 315 is configured to form a second arcuate surface 3151, which is used to cooperate with the foot pedal 320 to rotate independently of the door opening part 310, avoiding interference. The first limiting part 315 is also configured to form a fourth abutment surface 3152, which is located behind the second arcuate surface 3151 and is used to limit the foot pedal 320 from the stepped state to the unfolded state. The first limiting part 315 is also configured to form a fifth limiting surface, which is located in front of the second arcuate surface 3151 and is used to limit the stepped state of the foot pedal 320.

[0211] In some embodiments, the rod body 312, the first mounting wall 3121, the second mounting wall 314, the connecting wall 313, and the first limiting part 315 are integrally formed, which helps to improve the structural strength and stability of the door opening part 310.

[0212] Continue to refer to Figure 8The base 330 includes a base plate 331, which is fixedly connected to the bottom surface of the cabinet 100. The base 330 may also include two third mounting walls 332, which are spaced apart along the axial direction of the hinge shaft 340. Each of the two third mounting walls 332 has a second hinge hole 3321 for the hinge shaft 340 to pass through. (See reference...) Figure 11 The two third mounting walls 332 are located outside the two second mounting walls 314.

[0213] In this embodiment, the hinge shaft 340 passes through the second hinge hole 3321 to achieve connection with the base 330. Of course, this is not limiting; for example, the rear cover of the hinge shaft 340 can be rotatably connected to the base 330 or the door opening member 310 via a bearing.

[0214] In some embodiments, the base 330 is a one-piece molded component, which facilitates molding and helps ensure structural strength and stability.

[0215] Continue to refer to Figure 8 The hinge shaft 340 may include a shaft body 341, which passes through two first hinge holes 3141 and two second hinge shafts 340, so that the door opening member 310 can rotate relative to the base 330.

[0216] The end of the shaft body 341 facing away from the foot pedal 320 extends to the outside of the third mounting wall 332 and is fixedly connected to the retaining ring 380, thereby forming an axial limit at one end of the hinge shaft 340. Of course, the retaining ring 380 is not limiting; other structures can also be used to achieve axial limit at the end of the hinge shaft 340.

[0217] Continue to refer to Figure 8 A connecting head 342 is provided at the end of the hinge shaft 340 facing the foot pedal 320. The diameter of the connecting head 342 is larger than the diameter of the shaft body 341. The end of the connecting head 342 facing the hinge shaft 340 forms an end face. The end face contacts the outer side of another third mounting wall 332, serving to limit the axial movement of the hinge shaft 340. Figure 11 As shown, under the action of the snap ring 380 and the connecting head 342, the hinge shaft 340 is installed in the first hinge hole 3141 and the second hinge hole 3321.

[0218] In some embodiments, the hinge shaft 340 is rotatably connected to the first hinge hole 3141 and fixedly connected to the second hinge hole 3321. Thus, when the door opening member 310 and the foot pedal member 320 rotate about the central axis of the hinge shaft 340, the hinge shaft 340 rotates relative to the first hinge hole 3141.

[0219] In some embodiments, the hinge shaft 340 can be a single integral piece, which facilitates processing and helps ensure structural strength.

[0220] Continue to refer to Figure 8 In some embodiments of this application, the elastic element 360 can be a torsion spring. The torsion spring is sleeved on the shaft body 341 of the hinge shaft 340, and the two torsion arms of the torsion spring elastically abut against the door opening element 310 and the base 330, respectively.

[0221] like Figure 8 and Figure 11 As shown, the torsion spring may include a spring body 361, which is in the shape of a cylindrical elastic spring. The spring body 361 is sleeved on the hinge shaft 340 and is located between the two second mounting walls 314.

[0222] The torsion spring may also include two torsion arms, one of which abuts against the connecting wall 313 and the other abuts against the base plate 331 of the base 330.

[0223] For example, multiple spring bodies 361 may be provided, and the multiple spring bodies 361 are arranged at axial intervals along the hinge axis 340. The torsion arms of two adjacent spring bodies 361 are connected to form a first torsion arm 363. One of the connecting wall 313 and the base plate portion 331 abuts against the first torsion arm 363; the other abuts against the outer torsion arms of the two outermost spring bodies 361, thereby elastically mounting the elastic member 360 between the door opening member 310 and the base 330.

[0224] like Figure 8 As shown, there are two spring bodies 361. Two adjacent torsion arms of the two spring bodies 361 are connected to form a first torsion arm 363, which is approximately U-shaped. Combined with... Figure 11 The bottom surface of the base plate 331 is provided with a protruding locking part 333, which is located between two third mounting walls 332. The first torsion arm 363 is locked in the locking part 333 and elastically abuts against the bottom surface of the base plate 331.

[0225] like Figure 11 As shown, two torsion arms on the outer sides of the two spring bodies 361 form a second torsion arm 362, which abuts against the connecting wall 313. The connecting wall 313 forms a plane below the first arc-shaped surface, so that the second torsion arm 362 abuts against the plane, which helps to increase the contact area between the second torsion arm 362 and the plane, thereby improving the stability of the connecting wall 313 in limiting the torsion arm.

[0226] Before the door opening component 310 is subjected to a stepping force, the second torsion arm 362 and the first torsion arm 363 elastically abut against the base plate 331 and the connecting wall 313. When the door opening component 310 is subjected to a stepping force, the torsion spring undergoes elastic deformation. When the door opening component 310 loses the stepping force, the torsion spring returns to its original deformation, causing the door opening component 310 to return to its original state before being stepped on, thus preventing the door opening component 310 from affecting the closing of the door body 200.

[0227] According to the spring stiffness formula, k = (G·d 4 The stiffness of the elastic element 360 can be determined by ) / (8·D³·n). Where k is the spring stiffness; G is the shear modulus of the spring material; d is the diameter of the spring wire; D is the average diameter of the spring; and n is the effective number of coils in the spring.

[0228] For a torsion spring, the first torsion arm 363 and the second torsion arm 362 form a first angle in their natural state. When the torsion spring is subjected to force and deforms, a second angle is formed between the first torsion arm 363 and the second torsion arm 362. The difference between the second angle and the first angle is δ. Therefore, the torque of the torsion spring is T1 = kδ.

[0229] For example, the torque generated by the weight of the pedal 320 is 0.0428 N. A certain model has a torque of 3.03 N. The torque generated by the torsion spring itself is sufficient to support the pedal 320 in the pedaling position.

[0230] Continue to refer to Figure 8 The connecting portion 322 of the foot pedal 320 is sleeve-shaped and is sleeved on the outside of the connecting shaft 350, and the foot pedal 320 rotates relative to the connecting shaft 350. A limit structure is provided at the end of the connecting shaft 350 to prevent the connecting portion 322 of the foot pedal 320 from disengaging from the connecting shaft 350.

[0231] The end of the connecting part 322 is configured to form a second limiting part 323, which limits the first limiting part 315 and the connector head to limit the different states of the foot pedal 320.

[0232] The bottom of the connecting shaft 350 forms an insertion portion 351, the cross-section of which is non-circular, for example, the cross-sectional shape of which is polygonal. The connecting head 342 of the hinge shaft 340 is provided with a slot 343, into which the insertion portion 351 can be inserted to achieve the initial installation of the connecting shaft 350 and the hinge shaft 340.

[0233] The foot pedal opening mechanism 300 may further include a fixing member 370, which is fixedly connected to the hinge shaft 340 and the connecting shaft 350. For example, the fixing member 370 is threadedly connected to both the hinge shaft 340 and the connecting shaft 350, which not only helps ensure the reliability of the connection between the connecting shaft 350 and the hinge shaft 340, but also helps prevent the connecting shaft 350 from rotating relative to the hinge shaft 340, ensuring that when the foot pedal 320 rotates about the first central axis O1 of the hinge shaft 340, the foot pedal 320 will not rotate about the second central axis O2 of the connecting shaft 350.

[0234] The fastener 370 can be located at the end of the connecting head 342 for easy operation. Alternatively, the fastener 370 can also be located on the circumferential surface of the connecting head 342.

[0235] Reference Figure 3 In other embodiments of this application, the bottom end of the connecting portion 322 is configured to form a connecting shaft 350. A second limiting portion 323 is provided on the connecting portion 322, located above the connecting shaft 350. The connecting head 342 is provided with a connecting hole, allowing the connecting shaft 350 to be inserted into the connecting hole and rotate relative to the connecting hole.

[0236] The connecting shaft 350 is provided with an annular groove. The fixing member 370 extends radially along the connecting head 342 and is fixedly connected to the connecting head 342. The portion of the fixing member 370 that extends into the connecting hole mates with the annular groove on the connecting shaft 350, thereby confining the connecting shaft 350 within the connecting hole without affecting the rotation of the connecting shaft 350 relative to the connecting hole.

[0237] The foot pedal 320 in this embodiment of the application has a folded state, such as Figure 2 , Figure 4 and Figure 12 As shown; the foot pedal 320 in this embodiment of the application also has an unfolded state, as shown Figure 5 , Figure 6 as well as Figure 7 As shown; the foot pedal 320 in this embodiment of the application also has a stepped state formed at the stepped position, such as Figure 9 and Figure 10 As shown.

[0238] The embodiments of this application are provided with a reliable limiting structure so that the foot pedal 320 can be stably maintained in various states.

[0239] Reference Figure 2 and Figure 12When the foot pedal 320 is in the retracted state, the foot surface 3211 of the foot pedal 320 faces the side of the cabinet 100, and the door opening component 310 is located between the rear side 210 of the door 200 and the front side 110 of the cabinet 100, with the extension direction of the door opening component 310 perpendicular to the bottom surface of the cabinet 100. Alternatively, when the bottom plate portion 331 of the base 330 is a flat structure, the extension direction of the door opening component 310 is perpendicular to the bottom plate portion 331. Specifically, the extension direction of the rod portion 312 of the door opening component 310 is perpendicular to the bottom plate portion 331.

[0240] This arrangement facilitates the insertion of the door hinge 310 into the gap between the rear side 210 of the door 200 and the front side 110 of the cabinet 100 when the base plate 331 is fixed to the bottom surface of the cabinet 100. Figure 2 As shown, the possibility of the door opening component 310 colliding with the cabinet 100 and the door 200 is reduced, thus improving the convenience of installing the foot-operated door opening mechanism 300 into the cabinet 100.

[0241] To improve the reliability of the elastic element 360 installed between the connecting wall 313 and the base 330 of the door opening member 310, the elastic element 360 is elastically installed between the door opening member 310 and the base 330. This can be understood as follows: when the door opening member 310 is not subjected to a stepping force, i.e., when the foot pedal 320 is in the retracted, extended, or stepped-on state, the first torsion arm 363 elastically abuts against the base plate 331, and the torsion arm elastically abuts against the connecting wall 313.

[0242] In its natural state, the angle between the torsion arm and the first torsion arm 363 along the circumference of the spring body is greater than 90°. In the retracted state, the door opening component 310 abuts against the base 330, making the extension direction of the door opening component 310 perpendicular to the bottom surface of the cabinet 100. This arrangement facilitates the installation of the foot-operated door opening mechanism 300 in the retracted state and allows the elastic component 360 to be elastically installed between the base 330 and the door opening component 310 without the need for other fixings or limits on the elastic component 360, thus ensuring the stability of the installation of the elastic component 360.

[0243] Reference Figure 12 The front end of the base plate 331 forms a first abutment surface 3311; refer to Figure 8 and Figure 12 The second mounting wall 314 of the door opening component 310 is provided with a second abutment surface 3122 on its rear side. When the foot pedal 320 is in the retracted state, the second abutment surface 3122 abuts against the first abutment surface 3311, so that the extension direction of the rod portion 312 is perpendicular to the base plate portion 331.

[0244] In some embodiments, the foot pedal 320 and the hinge shaft 340 abut against each other to limit the position of the foot pedal 320 when it rotates from the unfolded state to the retracted state, and to create a gap between the foot pedal 320 and the side of the cabinet 100 in the width direction.

[0245] This design limits the position of the foot pedal 320 when it rotates from the unfolded state to the retracted state, preventing the foot pedal 320 from contacting the cabinet 100 and damaging its appearance.

[0246] Continue to refer to Figure 8 The hinge shaft 340 is configured to form a first limiting surface 3422, which intersects the axial direction of the hinge shaft 340. For example, the first limiting surface 3422 is perpendicular to the axial direction of the hinge shaft 340. When the foot pedal 320 rotates to abut against the first limiting surface 3422, the foot pedal 320 is in a retracted state.

[0247] The connecting head 342 is configured to form a first limiting surface 3422. Exemplarily, the connecting head 342 is configured to form a planar portion, and a slot 343 is disposed on the planar portion. A partial protrusion of the planar portion forms a third limiting portion 3421, which defines the first limiting surface 3422.

[0248] Continue to refer to Figure 8 The foot pedal component 320 forms a first mating surface 3231. The second limiting part 323 also forms the first mating surface 3231. Figure 12 The first mating surface 3231 abuts against the first limiting surface 3422 to limit the position of the foot pedal 320 when it rotates from the unfolded state to the retracted state, thus ensuring the stability of the retracted position.

[0249] Of course, in some implementations, the foot pedal 320 can be used to contact the side of the cabinet 100 along the width direction to limit the position of the foot pedal 320 in the retracted state.

[0250] Reference Figure 13 In some possible implementations, two third limiting portions 3421 are provided, and the two third limiting portions 3421 are arranged circumferentially at intervals along the connecting shaft 350. Each third limiting portion 3421 is provided with a first limiting surface 3422. Correspondingly, the second limiting portions 323 are respectively constructed to form two first mating surfaces 3231, and each first mating surface 3231 abuts against a first limiting surface 3422.

[0251] Thus, two limiting contacts are formed between the foot pedal 320 and the hinge shaft 340 in the circumferential direction of the connecting shaft 350, which helps to improve the reliability of the limiting in the retracted state.

[0252] In some embodiments, the hinge shaft 340 is configured to have a second limiting surface 3423, which is located in front of the first limiting surface 3422 and intersects with the first limiting surface 3422.

[0253] When the foot pedal 320 rotates to abut against the second limiting surface 3423, the foot pedal 320 is in the unfolded state.

[0254] The third limiting portion 3421 of the hinge shaft 340 is configured to form a second limiting surface 3423. For example, the second limiting surface 3423 is perpendicular to the first limiting surface 3422.

[0255] The second limiting part 323 of the foot pedal 320 is configured to form a second mating surface 3232, which can be parallel to the first mating surface 3231.

[0256] Continue to refer to Figure 13 In some possible implementations, two third limiting portions 3421 are provided, and the two third limiting portions 3421 are arranged at intervals along the circumference of the connecting shaft 350. Each third limiting portion 3421 is provided with a second limiting surface 3423. Correspondingly, the second limiting portion 323 is constructed to form two second mating surfaces 3232, and each second mating surface 3232 abuts against one second limiting surface 3423. In this way, two limiting abutments are formed between the foot pedal 320 and the hinge shaft 340 in the circumferential direction of the connecting shaft 350, which helps to improve the reliability of the limiting in the deployed state.

[0257] In this embodiment, the abutment of the second limiting surface 3423 and the second mating surface 3232 restricts the pedal component 320 from rotating to the unfolded state, ensuring that the unfolded state is in a stable position. Furthermore, the abutment of the second limiting surface 3423 and the second mating surface 3232 also limits the forward rotation of the pedal component 320 around the hinge axis 340, ensuring that the pedal component 320 does not rotate around the connecting axis 350 when rotating around the hinge axis 340, thus helping to ensure the stability of the pedal component 320 under the force of pedaling.

[0258] In other embodiments, when the foot pedal 320 rotates from the folded position to the side of the cabinet 100 away from the cabinet, and the door opening member 310 abuts against the foot pedal 320, the foot pedal 320 is in the unfolded state.

[0259] For example, when the pedal 320 is rotated to the point where the second limiting part 323 and the rod part 312 abut against the side of the pedal 320, the pedal 320 is in the unfolded state.

[0260] Thus, the unfolded state of the foot pedal 320 is limited by the contact limit between the foot pedal 320 and the door opening part 310; the limit can be achieved by the side of the door opening part 310, which is simple in structure and easy to implement.

[0261] It should be noted that when the door opening member 310 rod body 312 abuts against the foot pedal member 320 to restrict the unfolding position of the foot pedal member 320, it is also necessary to limit the rotation of the foot pedal member 320 around the connecting shaft 350 to ensure that the foot pedal member 320 does not rotate around the connecting shaft 350 when rotating around the hinge shaft 340.

[0262] Continue to refer to Figure 14 In some embodiments of this application, the hinge shaft 340 is configured to form a third abutment surface 3424, and the door opening member 310 is configured to form a fourth abutment surface 3152. When the foot pedal 320 rotates independently of the door opening member 310 from a stepped state to an unfolded state until the third abutment surface 3424 abuts against the fourth abutment surface 3152, the foot pedal 320 is in the unfolded state.

[0263] The connecting head 342 of the hinge shaft 340 is configured to form a third abutment surface 3424. The third abutment surface 3424 and the third limiting part 3421 are located at different positions circumferentially on the connecting head 342, and they do not interfere with each other. (Refer to...) Figure 8 The first limiting part 315 of the door opening component 310 is configured to form a fourth abutment surface 3152, which is located behind the second arc-shaped surface 3151.

[0264] The contact between the third contact surface 3424 and the fourth contact surface 3152 limits the position of the foot pedal 320 from the pedaled state to the unfolded state, thus preventing the foot pedal 320 from rotating excessively.

[0265] Continue to refer to Figure 8 In some embodiments of this application, the door opening member 310 is further configured to form a fifth abutment surface 3153; the fifth abutment surface 3153 is connected to the front side of the second arcuate surface 3151. When the foot pedal member 320 rotates about the hinge axis 340 to abut against the fifth abutment surface 3153, the foot pedal member 320 is in the stepping position.

[0266] Combination Figure 10 The second limiting part 323 of the foot pedal 320 is configured to form a sixth abutment surface 3233. When the sixth abutment surface 3233 abuts against the fifth abutment surface 3153, the foot pedal 320 is in a stepping state. The sixth abutment surface 3233 is located above the fifth abutment surface 3153.

[0267] In this embodiment, the contact between the fifth abutment surface 3153 and the sixth abutment surface 3233 allows the foot pedal 320 to drive the door opening component 310 to rotate around the first central axis O1 of the hinge shaft 340, thereby opening the door body 200 using the door opening component 310. Since the sixth abutment surface 3233 is located above the fifth abutment surface 3153, the foot pedal 320 can rotate independently of the door opening component 310, achieving separation of the fifth abutment surface 3153 and the sixth abutment surface 3233. This eliminates the need for an additional complex unlocking structure, simplifying the structure of the foot pedal door opening mechanism 300.

[0268] Reference Figure 15 At the foot-feeding position, the second central axis O2 is inclined upwards relative to the horizontal plane. This arrangement causes the flat foot pedal portion 321 of the foot pedal component 320 to be inclined upwards relative to the horizontal plane. The space under the foot pedal portion 321 includes not only the space below the bottom surface of the cabinet 100, but also the space where the foot pedal portion 321 is inclined upwards relative to the horizontal plane. Figure 16 As shown, this configuration helps to increase the foot pedal space of the foot pedal 321. On the one hand, it can improve the operation feel of stepping to open the door. On the other hand, the hinge shaft 340 transmits the rotation angle of the foot pedal 321 to the opening angle of the door opener 310, thereby giving the door opener 310 a larger opening angle and providing convenience for subsequent door opening.

[0269] In this embodiment, both the foot pedal 320 and the door opening component 310 rotate relative to the base 330 via a hinge shaft 340. The foot pedal 320 rotates from the stepping position to the open position, forming an open state; simultaneously, the door opening component 310 rotates to a second angle β until the door 200 is open. The first angle α of the foot pedal 320 is equal to the second angle β of the door opening component 310.

[0270] In some embodiments, the second angle β of the door opening member 310 can be 20° to 35°, balancing ease of operation. If the second angle β is less than 20°, it may result in insufficient pedal travel; if the second angle β is greater than 35°, sufficient space needs to be reserved for the foot pedal member 320.

[0271] In this embodiment, the door opening distance L is not limited, as long as it allows a finger to be inserted into the door gap to open the door. The door opening distance L is the interval between the front side 110 of the cabinet 100 away from the hinged end and the rear side 210 of the door 200 away from the hinged end, along the depth direction of the cabinet 100, when the door opening component 310 pushes open the door body 200.

[0272] For example, the door opening distance L can be 41mm to 43.4mm, such as 43mm. The first angle α can be 29°. Of course, this is not limiting and can be set according to the width of the locker door 200, the weight of the locker door 200, etc.

[0273] If the angle θ between the second central axis O2 and the horizontal plane is less than 15°, the foot pedal 320 has insufficient space to step down, resulting in insufficient opening angle of the door 200, thus increasing the convenience of opening the door 200 in the future.

[0274] If the angle θ between the second central axis O2 and the horizontal plane is greater than 17.5°, the foot pedal 320 will be significantly spaced from the storage cabinet's surface, increasing the difficulty of stepping on it and potentially requiring the user to lift their foot. This can easily lead to excessive stepping force, causing the foot pedal opening mechanism 300 to be overloaded and prone to damage.

[0275] Continue to refer to Figure 16 In some embodiments, the angle θ between the second central axis O2 and the horizontal plane is 15° to 17.5°. Figure 16 In the diagram, the black lines represent the door opener 310 and foot pedal 320 in the open state; the red lines represent the door opener 310 and foot pedal 320 in the step-on state.

[0276] This design allows the foot pedal 320 to have ample space to be stepped on, enabling it to rotate the door opening mechanism 310 to a sufficient angle for effective door opening. It also keeps the foot pedal 320 within the height range of the foot, conforming to stepping habits and ergonomics, thus improving ease of use. Furthermore, it avoids the foot pedal door opening mechanism 300 from being subjected to unnecessary overload impacts, ensuring its durability.

[0277] Continue to refer to Figure 15 In some embodiments of this application, the straight-line distance between the central axis of the roller 311 and the central axis of the hinge shaft 340 is defined as the rod length L1 of the door opening member 310, and the straight-line distance between the end of the foot pedal 320 away from the hinge shaft 340 and the central axis of the hinge shaft 340 is defined as the rod length L2 of the foot pedal 320. The ratio of the rod length L2 of the foot pedal 320 to the rod length L1 of the door opening member 310 can be 1 to 1.2, that is, the rod length L2 of the foot pedal 320 can be between 1 times L1 and 1.2 times L1. This ensures both the convenience of stepping to open the door and the opening angle; it also prevents the front end of the foot pedal 320 from protruding from the front surface of the door 200 during the opening process, thus ensuring the aesthetics of the storage cabinet.

[0278] When the ratio of the length L2 of the foot pedal 320 to the length L1 of the door opening component 310 is less than 1, the length L2 of the foot pedal 320 is less than the length L1 of the door opening component 310. Under the premise of ensuring the same door opening distance L, it is more difficult to open the door.

[0279] When the ratio of the length L2 of the foot pedal 320 to the length L1 of the door opening component 310 is greater than 1.2, the length of the foot pedal 320 is too large, which may cause the door body 200 to not reach the preset opening angle, while the foot pedal 320 has already touched the bottom surface, affecting the actual opening angle.

[0280] like Figure 16 As shown, in some embodiments of this application, when the foot pedal 320 is in the stepping state, the front end of the foot pedal 320 does not protrude from the front end of the second side 230 of the door body 200. This configuration ensures that the front end of the foot pedal 320 does not protrude from the front end of the first side 120 during the forward rotation of the foot pedal 320 around the first central axis O1 of the hinge shaft 340.

[0281] This design allows for a more compact operating space for the foot pedal, improving ease of operation; it also reduces the likelihood of the foot pedal 320 being impacted while in a footed position.

[0282] Reference Figure 16 In addition to the retracted, unfolded, and stepped states described above, the foot pedal 320 also has an open state. In the stepped state, the foot pedal 320 bears the stepping force and rotates forward and downward around the first central axis O1 of the hinge shaft 340, which drives the door opening component 310 to rotate, so that the door opening component 310 pushes open the door body 200.

[0283] In some embodiments, such as Figure 16 As shown, when the foot pedal 320 is in the open position, at least one of the door opening member 310 and the foot pedal 320 abuts against the base 330, and the foot pedal 320 is spaced from the placement surface of the storage cabinet.

[0284] For example, the connecting wall 313 of the door opening member 310 abuts against the bottom surface of the third mounting wall 332 of the base 330 to restrict the foot pedal 320 from being in the open state.

[0285] This design limits the end of the foot pedal path of the foot pedal 320, thereby restricting the opening angle of the door 200. Furthermore, when the foot pedal 320 is open, there is a gap between it and the storage cabinet surface, preventing the foot pedal 320 from touching the bottom surface and causing friction and damage to the floor.

[0286] In summary, the foot-operated door opening mechanism 300 of this application embodiment abuts against the first contact surface 3311 of the base plate portion 330 and the second contact surface 3122 of the door opening member 310, so that the rod portion 312 of the door opening member 310 is perpendicular to the base plate portion 331, which provides convenience for the installation of the foot-operated door opening mechanism 300.

[0287] The first limiting surface 3422 of the hinge shaft 340 abuts against the first mating surface 3231 of the foot pedal 320, providing a limit for the foot pedal 320 to return from the unfolded state to the retracted state, ensuring the stability of the retracted position.

[0288] The second limiting surface 3423 of the hinge shaft 340 abuts against the second mating surface 3232 of the pedal 320, providing a limit for the unfolded state of the pedal 320, and preventing the pedal 320 from not rotating around the connecting shaft 350 when rotating around the hinge shaft 340, which helps to ensure the stability of the pedal 320 under the pressure of pedaling force.

[0289] The hinge shaft 340 abuts against the third contact surface 3424 and the door opening component 310 fourth contact surface 3152, providing a limit for the foot pedal 320 to rotate backward from the stepping state to the unfolded state, preventing the foot pedal 320 from rotating too backward and affecting the convenience of stepping, and also providing a stable folding starting position for the foot pedal 320.

[0290] The foot pedal 320 is in a stepped state by abutting with the fifth abutting surface 3153 of the door opening component 310 and the sixth abutting surface 3233 of the foot pedal component 320. This allows the foot pedal 320 to drive the door opening component 310 to rotate through abutting, and also allows the foot pedal 320 to rotate independently of the door opening component 310 without the need for other structural settings.

[0291] The contact between the door opener 310 and the base 330 limits the path end of the foot pedal 320 and the door opener 310 to rotate forward, thereby limiting the opening angle of the door 200.

[0292] By setting limiters between the base 330, the door opening component 310, the hinge shaft 340, and the foot pedal 320, stable limiters are provided for the foot pedal 320 in various states, ensuring stable function implementation. Moreover, by distributing the limiter structure to multiple components, the structure of the foot pedal door opening mechanism is simplified.

[0293] With the above configuration, the foot-operated door opening mechanism 300 of this application embodiment achieves foot-operated door opening through the foot pedal 320 and the door opening component 310, freeing up the hands, increasing the number of door opening methods besides manual opening, and increasing the diversity of door opening methods. Furthermore, the foot-operated door opening mechanism of this application embodiment has at least the following advantages:

[0294] The foot pedal 320 has a folded state, which reduces the additional increase in the overall size of the locker caused by the foot pedal opening mechanism 300. This makes the locker's overall structure compact, facilitates the packaging and transportation of the locker, and helps reduce packaging and transportation costs.

[0295] The unfolded state of the foot pedal 320 is a transitional state between the stepped state and the retracted state. The foot pedal 320 rotates around the second central axis O2 to the unfolded position, forming the unfolded state, so that the foot surface 3211 of the foot pedal 320 rotates from the state facing the side of the cabinet 100 to the state facing the rear of the cabinet 100, providing a basis for the forward rotation of the foot surface 3211.

[0296] It should be noted that users can apply a stepping force from the unfolded state to open the door by foot. However, this application creatively changes this setting, setting the foot pedal 320 to rotate around the first central axis O1 from the unfolded position to the stepping position, forming a stepping state. In the stepping state, the foot pedal 320 bears the stepping force and drives the door opening component 310 to rotate together, so that the door opening component 310 pushes open the door body 200.

[0297] This means that, based on the unfolded state, the foot pedal 320 of this embodiment is constructed to have an innovative stepping state. On the one hand, this improves the convenience of stepping operation and reduces the difficulty of stepping operation; at the same time, it ensures that the path of rotation of the foot pedal 320 when stepped on is within an appropriate range, avoiding excessive stepping height that could easily overload and damage the foot pedal door opening mechanism 300. On the other hand, when in the stepping state, the foot pedal 320 can rotate independently relative to the door opening member 310 towards the unfolded state, providing a buffer space for the foot pedal 320 to absorb impact energy from accidental collisions or accidental touches, and also avoiding rigid collisions, reducing the pain felt by the user when colliding with the foot pedal 320, and improving the safety of the foot pedal door opening mechanism 300.

[0298] From the perspective that the foot pedal 320 can rotate independently of the door opening mechanism and from the stepped state to the unfolded state, the foot pedal 320 is constructed to have an unfolded state. This provides a limit to the rotation of the foot pedal 320 away from the stepping direction, so that even if the foot pedal 320 is subjected to an unexpected force and rotates from the stepped state to the unfolded state, the foot pedal 320 can still remain in a position between the unfolded and stepped positions. Compared to the folded state, the door can still be opened by foot. The existence of the unfolded state prevents the foot pedal 320 from directly returning to the folded state from the stepped state, which would increase the difficulty of foot-operated door opening.

[0299] It should be noted that, in the operation or use of the locker, the foot pedal 320 of the foot-operated door opening mechanism 300 of this embodiment is in a stepped state. When the foot pedal 320 is subjected to a stepping force, it can drive the door opening component 310 to open the door 200; the foot pedal 320 can rotate from the stepped state to the unfolded state under unexpected force; the locker can be in a folded state during transportation.

[0300] Of course, users can set the foot pedal 320 to any state according to their actual needs. For example, when the user does not need the foot pedal to open the door, the foot pedal 320 can be adjusted to the folded state to reduce the space occupied by the storage cabinet.

[0301] Furthermore, in this embodiment, when the foot pedal 320 is in a stepped state and bears the stepping force, it rotates forward around the first central axis O1, driving the door opening member 310 to rotate forward around the first central axis O1 to the open position, so that the door opening member 310 pushes open the door body 200. The foot pedal 320 and the door opening member 310 rotate forward around the same central axis, so that the rotation angle of the foot pedal 320 can be converted into the rotation angle of the door opening member 310, which is the opening angle of the door body 200. Therefore, it is convenient to adjust the opening angle of the door body 200 by setting the rotation angle of the foot pedal 320; the structure is simple and easy to implement.

[0302] The foot pedal 320 rotates from the unfolded state to the stepped state and from the stepped state to the open state, both in the same direction around the same central axis. This consistency in direction means that the foot pedal 320 can open the door by stepping on it, even if it is in the unfolded position or any position between the unfolded and stepped positions, without any other additional operation. This gives the foot pedal door opening mechanism 300 good fault tolerance, strong robustness, and reliability.

[0303] Another innovation of the foot pedal door opening mechanism 300 in this application embodiment is that during the process of the foot pedal 320 rotating from the unfolded state to the open state, the formation between the unfolded state and the stepping state of the foot pedal 320 is an idle stroke that does not drive the door opening member 310 to rotate. During this rotation stroke, the foot pedal 320 rotates independently of the door opening member 310, providing upward space for the foot pedal 320 to flip up in case of accidental collision at the stepping position, thereby improving the safety of foot pedal door opening; moreover, the impact on the user's stepping experience is very small, or even negligible.

[0304] It should also be noted that, such as Figure 8 As shown, the foot-operated door opening mechanism 300 of this application embodiment has a number of parts that can be less than a single digit, yet it can achieve the above-mentioned multiple functions and effects. It has a simple structure, is easy to implement, and has low cost.
