Description

Technical Field

[0001] This utility model relates to the field of logistics technology, and in particular to an anti-accidental door closing mechanism, a locker, and a logistics device. Background Technology

[0002] With the development of the logistics industry, logistics vehicles capable of mobile vending or autonomous delivery of goods are gradually being applied to the market to better meet users' needs for purchasing or picking up goods and reduce labor costs.

[0003] Logistics vehicles are typically equipped with cargo boxes for storing goods. Existing technology provides a cargo box structure that adopts a double-door structure. The right door is equipped with a locking hook, and the inside of the box is equipped with a door lock that cooperates with the locking hook. The left door has a left flap on the right side and a right flap on the left side. When closing normally, the left door closes first. After the right door closes, the right flap presses against the front of the left flap, and the locking hook engages with the door lock, thereby achieving the closure of both doors.

[0004] However, when implementing the technical solution, the inventors discovered that users might mistakenly close the right side door first and then the left side door after picking up the goods. This would cause the right side door to lock with the door lock after it is closed, making it impossible to close the left side door. This would result in the cargo box not being able to close completely, affecting its subsequent use. It would also cause the open left side door to scrape against people or goods during transportation, affecting the safety of the logistics vehicle. Utility Model Content

[0005] The purpose of this utility model embodiment is to provide an anti-accidental closing mechanism, a locker, and a logistics device, which can reduce the probability of the side of the double-door locker with the locking hook being accidentally closed, and improve the reliability of the locker's closing operation.

[0006] To achieve this objective, the present invention adopts the following technical solution:

[0007] An anti-accidental door closing mechanism includes a mounting base, an elastic element, and a rotating base. The rotating base and the mounting base are rotatably connected so that the rotating base can rotate and switch between a first position and a second position relative to the mounting base. The rotation axis of the rotating base extends along a first direction, and the rotating base has a first pressing part and a second pressing part arranged sequentially in the first direction.

[0008] When the rotating seat is in the first position, the second pressing part and the mounting seat are arranged sequentially in the second direction. The first pressing part is arranged at an angle to the second pressing part along the extension direction away from the mounting seat, so that the rotating seat can rotate to the second position when the first pressing part is subjected to an external force along the second direction and toward the mounting seat. The second direction is arranged at an angle to the first direction.

[0009] The elastic element is connected between the rotating seat and the mounting seat, and the elastic element is used to apply an elastic force to the rotating seat to keep or return the rotating seat to the first position.

[0010] As an optional technical solution for an anti-accidental door closing mechanism, the end of the first pressing part away from the mounting base forms a first pressing end, and the end of the second pressing part away from the mounting base forms a second pressing end;

[0011] A plane passing through the rotation axis and parallel to the second direction is defined as the rotation reference plane, and the first pressing end and the second pressing end are located on opposite sides of the rotation reference plane.

[0012] As an optional technical solution for the anti-accidental door closing mechanism, the second pressing part is a plate-shaped structure, and when the rotating seat is in the first position, the second pressing part is parallel in the second direction;

[0013] And / or, the second pressing end has a limiting surface, which is perpendicular to the second direction when the rotating seat is in the first position.

[0014] As an optional technical solution for the anti-accidental closing mechanism, the second pressing part has a first side and a second side that are arranged opposite to each other. In a projection plane perpendicular to the first direction, the orthographic projection of the second side is relative to the orthographic projection of the first side near the first pressing end. The second side and the limiting surface are connected by a smooth arc transition.

[0015] As an optional technical solution for the anti-accidental door closing mechanism, the first pressing end is an arc structure, and the opening of the arc structure faces the other end of the first pressing part;

[0016] And / or, when the rotating seat is in the first position, the angle between the extending direction of the first pressing part and the rotating reference surface is 30° to 60°.

[0017] As an optional technical solution for an anti-accidental door closing mechanism, the anti-accidental door closing mechanism has a rotation limiting structure, which restricts the rotating seat in the first position from rotating in a direction away from the second position;

[0018] And / or, in the first direction, the first pressing portion and the second pressing portion are spaced apart.

[0019] As an optional technical solution for an anti-accidental door closing mechanism, the rotation limiting structure includes a first stop surface disposed on the side of the mounting base near the rotating seat and a second stop surface disposed on the side of the rotating seat near the mounting base. When the rotating seat is in the first position, the first stop surface and the second stop surface are in contact.

[0020] As an optional technical solution for an anti-accidental closing mechanism, the anti-accidental closing mechanism further includes a hinge structure. The two hinge plates of the hinge structure are respectively connected to the mounting base and the rotating base. The elastic element is a torsion spring, which is sleeved on the rotating shaft of the hinge structure, and the two ends of the torsion spring respectively press against the two hinge plates.

[0021] A storage cabinet includes a cabinet body, which includes a cabinet body with an open side and a first door and a second door that are arranged in a double-opening manner at the open end of the cabinet body. The cabinet body is equipped with a door lock, and the second door is equipped with a lock hook. It also includes an anti-accidental closing mechanism as described above. A mounting base is installed on the cabinet body. A first pressing part is disposed opposite to the first door, and a second pressing part is disposed opposite to the second door. When both the first door and the second door are open, the rotating base is in the first position, and the ends of the first pressing part and the second pressing part away from the mounting base extend out of the open side.

[0022] A logistics device comprising a locker as described above.

[0023] The beneficial effects of this utility model embodiment:

[0024] The anti-accidental closing mechanism, locker, and logistics device provided in this embodiment of the utility model have a mounting base for cooperating with the locker body, improving the ease of installation of the anti-accidental closing mechanism on the locker body. Because the first pressing part extends outwards from the end away from the mounting base when the rotating base is in the first position, when the first locker door closes first, the first locker door contacts and presses against the front end of the first pressing part. Since the first pressing part is angled with the second pressing part along its extension direction away from the mounting base, the closing action of the first locker door forces the rotating base to rotate, thereby allowing the second pressing part to rotate with the first pressing part to the second position, releasing the second locker door from its closing position, ensuring that the second locker door can close smoothly after the first locker door is closed. When the first door closes, the second door acts on the front end of the second pressing part and applies a pressing force towards the mounting base. Since the second pressing part and the mounting base are arranged sequentially in the second direction when the rotating base is in the first position, the second pressing part is restricted from rotating when it is pressed towards the mounting base. Thus, the second pressing part can be used to abut against the second door, restricting the second door from closing further, thereby preventing the second door from closing before the first door. This prevents the first door from failing to lock due to the second door closing accidentally, improving the reliability of the locker's closing and thus improving the reliability of the locker's use. Furthermore, this anti-accidental closing mechanism has a simple structure, occupies little space, has low cost, and is easy to implement. Attached Figure Description

[0039] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

[0040] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0041] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0042] In the description of this embodiment, the terms "upper," "lower," "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0043] This embodiment provides a storage cabinet that can be used in logistics vehicles to temporarily store goods, and it can also be used in other places where items need to be temporarily stored or preserved.

[0044] like Figures 1 to 11 As shown, the storage cabinet includes a main body, which comprises a cabinet body 200 with an open side and a first door 300 and a second door 400 arranged in a double-opening configuration at the open end of the cabinet body 200. Specifically, the end of the first door 300 away from the second door 400 is hinged to the cabinet body 200, and the other end has a first flange. The end of the second door 400 away from the first door 300 is hinged to the cabinet body 200, and the other end has a second flange. The cabinet body 200 is equipped with a lock, and the second door 400 is equipped with a locking hook. When both the first door 300 and the second door 400 are closed, the second flange overlaps the front of the first flange. The locking hook cooperates with the lock to lock the first door 300 and the second door 400 relative to the cabinet body 200, and the first door 300 and the second door 400 together close the open end of the cabinet body 200 to ensure that items inside the storage cabinet will not fall out.

[0045] In this embodiment, to prevent the second door 400 from closing before the first door 300, thus preventing the first door 300 from being locked, the locker also includes an anti-accidental closing mechanism 100, which includes a mounting base 1, an elastic element 4, and a rotating base 2. The rotating seat 2 and the mounting seat 1 are rotatably connected so that the rotating seat 2 can rotate and switch between a first position and a second position relative to the mounting seat 1. The rotation axis of the rotating seat 2 extends along a first direction. The rotating seat 2 has a first pressing part 21 and a second pressing part 22 arranged sequentially in the first direction. When the rotating seat 2 is in the first position, the second pressing part 22 and the mounting seat 1 are arranged sequentially in the second direction. The first pressing part 21 is arranged at an angle to the second pressing part 22 along the extension direction away from the mounting seat 1 so that the rotating seat 2 can rotate to the second position when the first pressing part 21 is subjected to an external force along the second direction and toward the mounting seat 1. The second direction is arranged at an angle to the first direction. An elastic member 4 is connected between the rotating seat 2 and the mounting seat 1, and the elastic member 4 is used to apply an elastic force to the rotating seat 2 to keep or return the rotating seat 2 to the first position.

[0046] Mounting base 1 is installed on the inner top wall or inner bottom wall of the housing 200. The first pressing part 21 is set opposite the first door 300, and the second pressing part 22 is set opposite the second door 400. When both the first door 300 and the second door 400 are opened, the rotating base 2 is in the first position, and the ends of the first pressing part 21 and the second pressing part 22 away from the mounting base 1 both extend out of the opening.

[0047] The anti-accidental closing mechanism 100 and the storage cabinet provided in this embodiment have a mounting base 1 for cooperating with the cabinet body 200, improving the ease of installation of the anti-accidental closing mechanism 100 on the cabinet body 200. Since the first pressing part 21 extends outward from the mounting base 1 when the rotating seat 2 is in the first position, when the first door 300 closes first, the first door 300 contacts and presses against the front end of the first pressing part 21. Because the first pressing part 21 is angled with the second pressing part 22 along its extension direction away from the mounting base 1, the closing action of the first door 300 presses the rotating seat 2 to rotate, thereby allowing the second pressing part 22 to rotate with the first pressing part 21 to the position where it releases the closing of the second door 400, ensuring that the second door 400 can close smoothly after the first door 300 is closed. When the first door 300 is closed, the second door 400 acts on the front end of the second pressing part 22 and applies a pressing force to the second pressing part 22 in the direction toward the mounting base 1. Since the second pressing part 22 and the mounting base 1 are arranged sequentially in the second direction when the rotating base 2 is in the first position, the second pressing part 22 is restricted from rotating when it is pressed toward the mounting base 1. Thus, the second door 400 is restricted from continuing to close by the second pressing part 22, thereby preventing the second door 400 from closing before the first door 300. This prevents the problem of the first door 300 failing to lock due to the second door 400 closing accidentally, thus improving the closing reliability of the locker and improving the usability of the locker. Furthermore, this anti-accidental closing mechanism 100 has a simple structure, occupies little space, has low cost, and is easy to implement.

[0048] In this embodiment, the first door 300 and the second door 400 are arranged side by side in the horizontal direction. The mounting base 1 is installed on the inner top wall or inner bottom wall of the box body 200. The first direction is the side-by-side arrangement direction of the first door 300 and the second door 400, that is, the width direction of the box body 200. The second direction is the horizontal direction and the depth direction of the inner cavity of the box body 200.

[0049] In other embodiments, the first door 300 and the second door 400 can also be arranged side by side in the height direction, as long as the first direction is the side-by-side arrangement direction of the first door 300 and the second door 400, and the second direction is the depth direction of the box body 200.

[0050] The mounting base 1 has a second side 12 opposite to the first side 11, and the second side 12 is connected to the inner wall of the housing 200. In this embodiment, the anti-accidental closing mechanism 100 is mounted on the inner top wall of the housing 200, the upper side of the mounting base 1 forms the second side 12, the lower side forms the first side 11, and the first pressing part 21 extends downward at an angle away from the mounting base 1. In other embodiments, the anti-accidental closing mechanism 100 may also be mounted on the inner bottom wall of the housing 200.

[0051] This invention describes the specific structure and implementation principle of the anti-accidental closing mechanism 100 by taking the first door 300 and the second door 400 as being arranged horizontally side by side and the anti-accidental closing mechanism 100 being installed on the inner top wall of the box body 200 as an example. However, it is understood that when the anti-accidental closing mechanism 100 is installed in other positions, its structure and implementation principle can be set with reference to this embodiment, and this embodiment will not describe them one by one.

[0052] To simplify the structure of the rotating seat 2, in this embodiment, the end of the first pressing part 21 away from the mounting seat 1 forms a first pressing end, and the end of the second pressing part 22 away from the mounting seat 1 forms a second pressing end; a plane passing through the rotation axis and parallel to the second direction is set as the rotation reference plane, and the first pressing end and the second pressing end are located on opposite sides of the rotation reference plane.

[0053] Therefore, when the first door 300 applies pressure to the first pressing part 21, the pressure on the first pressing part 21 is converted into a rotational torque that causes it to flip in the direction toward the first side 11, thereby pushing the first pressing part 21 to flip in the direction toward the first side 11; and when the rotating seat 2 is in the first position and the second door 400 closes before the first door 300, the horizontal pressure on the second pressing part 22 is converted into a force that causes the second pressing part 22 to flip upward, and due to the restriction of the upper side wall of the opening, the second pressing part 22 is restricted from flipping upward, thereby restricting the second door 400 from closing.

[0054] Specifically, in this embodiment, the rotation reference plane is a horizontal plane. When the rotating seat 2 is in the first position, the first pressing end and the second pressing end are located on opposite sides of the horizontal plane where the rotation axis is located. The first pressing end is lower than the horizontal plane where the rotation axis is located, and the second pressing end is higher than the plane where the rotation axis is located. When the first box door 300 applies a pressing force to the first pressing part 21, the first pressing part 21 flips downward and backward.

[0055] In other embodiments, the anti-accidental closing mechanism 100 can also be installed on the inner bottom wall of the housing 200, that is, the upper side of the mounting base 1 forms the first side 11, and the lower side of the mounting base 1 forms the second side 12. The end of the first pressing part 21 away from the mounting base 1 is higher than the horizontal plane where the rotation axis is located, and the end of the second pressing part 22 away from the mounting base 1 is lower than the plane where the rotation axis is located.

[0056] In this embodiment, the anti-accidental closing mechanism 100 has a rotation limiting structure, which restricts the rotation of the rotating seat 2 in the first position from rotating in a direction away from the second position. That is, the rotation limiting structure restricts the rotation of the rotating seat 2 in the first position from rotating in a direction toward the first side 11 of the mounting base 1. This improves the rotation reliability of the rotating seat 2. In other embodiments, the corresponding side edge of the opening may also restrict the rotation of the rotating seat 2 in a direction toward the second side 12.

[0057] In this embodiment, the rotation limiting structure includes a first stop surface disposed on the side of the mounting base 1 near the rotating seat 2 and a second stop surface disposed on the side of the rotating seat 2 near the mounting base 1. When the rotating seat 2 is in the first position, the first stop surface and the second stop surface are in contact. Thus, by the engagement of the end faces of the rotating seat 2 and the mounting base 1 at opposite ends, the rotation of the rotating seat 2 in the direction toward the first side 11 is restricted. In other embodiments, other rotation limiting structures may also be provided. For example, a stop portion may be provided protruding from the end face of the mounting base 1 toward the rotating seat 2. When the mounting base 1 is in the first position, the stop portion abuts against the rotating seat 2 to stop the rotating seat 2 from rotating in the direction toward the second side 12.

[0058] In this embodiment, when the first door 300 is closed, the first door 300 can push the rotating seat 2 to an intermediate position between the first and second positions via the first pressing part 21. When the rotating seat 2 is in the intermediate position, the second pressing end extends out of the opening of the box body 200, and the first pressing end and the second pressing end are located on the same side of the rotation reference surface. Thus, when the second door 400 is closed, it will abut against the second pressing end, thereby causing the second pressing part 22 to flip as the second door 400 continues to close until the second door 400 is completely closed, while the rotating seat 2 rotates to the second position. This arrangement ensures that the setting of the second pressing part 22 does not affect the continued closing of the second door 400; at the same time, when the lock hook and door lock are unlocked, the second pressing part 22 can apply a forward pressing force to the second door 400 under the action of the elastic member 4, causing the second door 400 to open, thereby improving the convenience of opening the door.

[0059] In other embodiments, when the first door 300 is closed, the first door 300 can push the rotating seat 2 to the second position through the first pressing part 21, and when the rotating seat 2 is in the second position, the second pressing part 22 is located inside the box body 200, that is, the second door 400 will no longer abut against the second pressing part 22 when it is closed, or when the second door 400 is closed in place, the second door 400 just abuts against the second pressing part 22.

[0060] In this embodiment, the anti-accidental closing mechanism 100 includes a hinge structure 3. The two hinge plates 31 of the hinge structure 3 are respectively connected to the mounting base 1 and the rotating base 2. The elastic element 4 includes a torsion spring, which is sleeved on the rotating shaft 32 of the hinge structure 3, and the two ends of the torsion spring press against the two hinge plates 31 respectively. By using the hinge structure 3 to realize the rotational connection between the mounting base 1 and the rotating base 2, the structure is simple and easy to implement, which simplifies the structure of the mounting base 1 and the rotating base 2 and improves the convenience of disassembly and assembly. At the same time, the torsion spring allows the two hinge plates 31 to maintain or return to a relatively unfolded state, thereby keeping the rotating base 2 in a relatively unfolded state.

[0061] In other embodiments, the mounting base 1 and the rotating base 2 can also be rotatably connected using other rotating connection structures. For example, the mounting base 1 may have two mounting ears spaced apart along the circumferential direction of rotation on one side, and the rotating base 2 may have an integral shaft structure on one side, with both ends of the shaft structure rotatably inserted into the mounting ears. That is, any other existing structures capable of rotatably connecting the two bases can be applied to this embodiment, and this embodiment does not impose specific limitations on the rotatable connection structure between the mounting base 1 and the fixed base.

[0062] In this embodiment, a hinge is connected to the first side 11 of the mounting base 1 to prevent the hinge structure 3 from affecting the installation of the mounting base 1 on the housing 200. The mounting base 1 and the housing 200 are preferably connected by screws to ensure the installation stability of the mounting base 1.

[0063] The rotating base 2 also includes a rotating connecting portion 23, which extends along a first direction and is rotatably connected to the mounting base 1. The ends of the first pressing portion 21 and the second pressing portion 22 facing the mounting base 1 are both connected to the side of the rotating connecting portion 23 away from the mounting base 1, thereby improving the ease of connection between the rotating base 2 and the mounting base 1. Specifically, a hinge is fixedly connected to the rotating connecting portion 23 by screws.

[0064] To simplify the structure of the second pressing part 22, the second pressing part 22 is a plate-shaped structure, and when the rotating seat 2 is in the first position, the second pressing part 22 is parallel in the second direction. That is, in this embodiment, when the rotating seat 2 is in the first position, the second pressing part 22 is horizontally arranged. This arrangement ensures that when the rotating seat 2 is in the first position, the direction of the pressing force from the second door 400 on the second pressing part 22 is consistent with the extension direction of the second pressing part 22, reducing the probability of the second pressing part 22 breaking due to excessive local stress and improving the safety of the rotating seat 2. At the same time, when the first pressing part 21 is pressed and drives the rotating seat 2 to rotate to the middle position, the second pressing part 22 tilts towards the first side 11 in the direction away from the mounting seat 1, which is more conducive to the second door 400 pushing the second pressing part 22 to rotate towards the first side 11.

[0065] In this embodiment, since the mounting base 1 is installed on the top wall of the housing 200, when the rotating base 2 is in the first position, the second pressing part 22 is located on the upper side of the rotation axis. Furthermore, the rotating connecting part 23 and the second pressing part 22 are integrally formed plate structures to simplify the overall structure of the rotating base 2.

[0066] Furthermore, the second pressing end has a limiting surface 221. When the rotating seat 2 is in the first position, the limiting surface 221 is perpendicular to the second direction. This ensures that when the rotating seat 2 is in the first position and the second door 400 abuts against the second pressing part 22, the limiting part contacts or makes line contact with the door surface, enhancing the reliability of the second pressing part 22 in limiting the second door 400. Specifically, in this embodiment, when the rotating seat 2 is in the first position, the limiting surface 221 is vertically arranged.

[0067] In this embodiment, the second pressing part 22 has a first side surface and a second side surface disposed opposite to each other. In a projection plane perpendicular to the first direction, the orthographic projection of the second side surface is relative to the orthographic projection of the first side surface near the first pressing end. The second side surface and the limiting surface 221 are smoothly connected by an arc surface 222. This ensures that when the rotating seat 2 rotates to the middle position, the arc surface 222 makes point contact with the second door 400, thereby ensuring the smoothness and reliability of the second door 400 pushing against the second pressing part 22.

[0068] Specifically, in this embodiment, the limiting surface 221 and the upper side of the second pressing part 22 are smoothly connected by an arc surface 222. In other embodiments, the lower side of the mounting base 1 is the first side 11, and the lower side of the second pressing part 22 and the lower end of the limiting surface 221 are smoothly connected by an arc surface 222.

[0069] Furthermore, the first pressing part 21 and the second pressing part 22 are spaced apart along the first direction, thereby preventing the first pressing part 21 from contacting the second door 400 or the second pressing part 22 from contacting the first door 300, improving the reliability of the anti-misoperation closing mechanism 100, reducing interference between structures, and reducing the processing difficulty of the rotating seat 2.

[0070] In this embodiment, when the rotating seat 2 is in the first position, the angle between the extending direction of the first pressing part 21 and the rotation reference surface is 30° to 60°. This arrangement makes the end of the first pressing part 21 facing the mounting seat 1 close to the rotation axis, while the distance between the free end of the first pressing part 21 and the rotation reference surface is relatively large. This ensures the convenience of rotational connection between the rotating seat 2 and the mounting seat 1, facilitates the rotation of the first door 300 by pressing against the first pressing part 21, and simplifies the structure of the first pressing part 21.

[0071] Furthermore, the first pressing end is an arc structure 211, with the opening of the arc structure 211 facing the other end of the first pressing part 21. This allows the arc structure 211 to contact the first door 300 when the first pressing part 21 abuts against it. The contact position between the arc structure 211 and the first door 300 is a line position extending along the rotation axis, which can increase the smoothness of the first door 300 pushing against the first pressing part 21.

[0072] In this embodiment, the upper side of the first pressing part 21 is tangentially connected to the arc structure 211, so that the first pressing part 21 will not have any sharp edges on the side that contacts the first door 300. Furthermore, the lower side of the first pressing part 21 is tangentially connected to the arc structure 211, so that the overall shape of the first pressing part 21 is simpler and the processing difficulty of the first pressing part 21 is reduced.

[0073] In other embodiments, when the upper side of the mounting base 1 is the first side 11, the first pressing part 21 is tangentially connected to the arc structure 211 at least on its lower side.

[0074] This embodiment also provides a logistics device, including the aforementioned locker. By employing the locker, the convenience of storing items and its use can be improved, thereby enhancing the ease of use and reliability of the logistics device. The logistics device may be, but is not limited to, unmanned vehicles, etc.
