[0037] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings. Those skilled in the art will appreciate that these descriptions are merely illustrative and exemplary and should not be construed as limiting the scope of protection of the present invention.

[0038] It should be noted that like reference numerals denote like items in the following drawings, and therefore, once an item is defined in one drawing, it will not be further defined or explained in the subsequent drawings.

[0039] like Figures 1 to 3 As shown, the locker 100 includes a cabinet body 10 with a storage space, two cabinet doors 18 and two sets of electric door openers 20. The electric door openers 20 are used to open and close the cabinet doors 18 respectively.

[0040] The cabinet body is the main body of the storage cabinet, and is composed of a bottom plate 11, a back plate 12, two side plates 13 and a top plate 14 to form a sturdy frame. This structural design ensures the stability and durability of the cabinet body, while also providing sufficient storage space for clothes. The cabinet doors 18 are hinged to the two side plates 13 of the cabinet body through a hinge structure, allowing the door body to open and close freely within a certain angle range. Each cabinet door 18 is equipped with a set of electric door openers 20, which use electric push rods and other mechanical components to realize automatic opening and closing of the cabinet doors. The electric door openers 20 configured on the cabinet body can be perfectly integrated with our company's electric clothes drying machine, making the drying and storage process of clothes smoother and more automated.

[0041] It should be noted that the electric door opener 20 in this embodiment is provided for the following reasons: in the event of a power outage or malfunction, the design of the electric door opener ensures that the cabinet door can still be opened manually, thus avoiding the risk of not being able to open the wardrobe. Moreover, the electric push rod of the electric door opener is hidden in the top plate, which saves space and prevents the electric push rod from occupying valuable storage space. In other words, the technical means formed by the electric door opener 20 in this technical solution, through the hidden electric push rod and the sophisticated connecting rod mechanism, realizes the automatic control of the door body while maintaining the beauty and practicality of the locker.

[0042] like Figures 4 to 8 As shown, the electric door opener 20 includes an electric push rod 21 located on the upper side of the top plate 14, an active rod 22, a rotating shaft 23 passing through the top plate 14, and a lower connecting rod assembly 24 located on the lower side of the top plate 14. The electric push rod 21 of the electric door opener 20 is driven by a motor to achieve the push and pull action of the telescopic rod 211.

[0043] Specifically, the telescopic rod 211 of the electric push rod 21 is connected to the upper end of the rotating shaft 23 via the active rod 22. One end of the lower connecting rod assembly 24 is connected to the lower end of the rotating shaft 23, and the other end of the lower connecting rod assembly 24 is connected to the cabinet door 18. The telescopic movement of the electric push rod 21 drives the cabinet door 18 to open and close. The active rod 22 connects the electric push rod 21 and the rotating shaft 23. The rotating shaft 23 passes through the top plate 14, allowing the active rod 22 to rotate around it, thereby converting the power of the electric push rod into the opening or closing movement of the cabinet door. Preferably, bearings are installed at the upper and lower ends of the rotating shaft 23 to ensure smooth rotation.

[0044] Preferably, the active rod 22 is generally made of a high-strength material to ensure stability and durability when transmitting force.

[0045] The lower connecting rod assembly 24 is located on the lower side of the top plate 14, and includes a driven rod 241 and a connecting push rod 242. The first end of the driven rod 241 is connected to the lower end of the rotating shaft 23, the second end of the driven rod 241 is connected to the first end of the connecting push rod 242, and the second end of the connecting push rod 242 is connected to the cabinet door 18 through the door insert 25, so that the rotation of the rotating shaft 23 can be converted into opening and closing of the cabinet door.

[0046] It's also worth noting that a mounting bracket 15 is located on the upper side of the top plate 14 to ensure stable installation and operation of the electric door opener 20. A bearing 16 is provided on the mounting bracket 15, through which the rotating shaft 23 passes. This allows the rotating shaft 23 to pass smoothly and rotate, reducing friction and wear, and improving the lifespan and efficiency of the entire electric door opener.

[0047] The use of the bearing 16 not only ensures the stable operation of the rotating shaft 23 , but also plays a supporting role, so that the electric push rod 21 can effectively transmit power through the active rod 22 .

[0048] In addition, preferably, a mounting base 16 is fixed to the top plate 14 in this embodiment, and the bottom of the electric linear actuator 21 is pivotally connected to the mounting base 16 via a pivot portion 17, which provides a stable and strong connection point for the electric linear actuator 21. This technical means allows the electric linear actuator to rotate during extension and retraction, thereby reducing interference with the interior space of the cabinet and ensuring the smooth and flexible operation of the electric linear actuator.

[0049] More specifically, the door insert 25 features a U-shaped vertical cross-section, a structure that optimizes its stability and load-bearing capacity. The inner vertical insert wall 251 and the outer fixed wall 252 are two key components of the U-shaped door insert. The inner vertical insert wall 251 snaps into a slot g defined within the upper frame strip 181 of the cabinet door 18. This ensures a tight fit between the door insert 25 and the upper frame strip, providing a secure connection point.

[0050] The outer fixing wall 252 abuts against the inner surface of the upper frame strip 181, further strengthening the connection between the door insert 25 and the cabinet door 18. The fastener t is a screw that passes through the outer fixing wall 252, the upper frame strip 181, and the inner insert wall 251 in sequence to secure the door insert 25 to the cabinet door 18. Specifically, the outer fixing wall 252 has a through hole for the screw, and the inner insert wall 251 has a threaded hole that mates with the screw. After the screw is tightened into the threaded hole, the screw head abuts against the wall of the upper frame strip 181 and is accommodated in the through hole of the outer fixing wall 252. The outer fixing wall 252 abuts against the inner surface of the cabinet door upper frame strip 181, providing additional support and strength to the connection and ensuring the stability of the door insert 25 during long-term use.

[0051] In addition, a connecting ear p is installed at the upper end of the outer fixed wall 252 of the door insert 25, and the second end of the connecting push rod 242 is connected to the connecting ear p by a fastener, which is a half-thread screw e. In this way, the connecting push rod 242 and the inner insert 25 can rotate relative to each other and the gap between them is small. The small gap helps to avoid the problem of the cabinet door rebounding back and forth due to the inertia when opening the door, thereby ensuring the smoothness and stability of the cabinet door opening and closing.

[0052] Furthermore, the above-described technical approach allows the door insert 25 to be relatively easily replaced or repaired when necessary, as the fasteners t can be quickly removed. The U-shaped design of the door insert 25 and the use of the fasteners t together ensure a reliable connection between the cabinet door 18 and the electric door opener 20, which is crucial for achieving smooth, automatic opening and closing of the cabinet door.

[0053] More preferably, retaining springs 26 are sleeved on both the upper and lower ends of the rotating shaft 23 to reduce radial displacement of the active rod 22 and the driven rod 241 relative to the rotating shaft 23. The presence of retaining springs 26 on both ends of the rotating shaft 23 effectively limits axial movement of these components, thereby ensuring their securement and positioning on the rotating shaft. By limiting axial movement of the components, retaining springs 26 prevent damage to the components due to vibration or impact.

[0054] Since the installation and removal of the retaining spring 26 are relatively simple, it is more convenient to maintain or replace the components on the rotating shaft.
