Description

Technical Field

[0001] This application relates to the field of logistics transportation equipment technology, specifically to a vehicle-mounted logistics box hoisting connection structure, hoisting system, and vehicle. Background Technology

[0002] Vehicle-mounted logistics containers are mainly used for transporting various goods and are suitable for various application scenarios such as manufacturing plants, supermarkets, express delivery, and personal use. They offer advantages such as mobility, ease of operation, high efficiency, large transport capacity, efficient space utilization, and safety and reliability.

[0003] However, existing lifting devices (or lifting equipment) are generally gripping claws or lashing hooks. When gripping or lashing vehicle-mounted logistics containers, gripping claws require many auxiliary structures, such as gripping drive devices, gripping structures, rotation drive devices, and release drive devices, which are relatively complex and prone to failure. As for lashing hooks, they require manual binding and unbinding of the hook to the vehicle-mounted logistics container, making the lifting process time-consuming, labor-intensive, and inefficient.

[0004] The applicant retrieved the following existing related technologies using the search query "(lifting or hoisting or suspension or raising) and (box or cargo box or logistics box)":

[0005] The prior art 1, Chinese patent document with publication number CN110921520B (a hoisting device for logistics transportation), uses a binding hook hoisting device, which uses a structure such as a hook and wire rope to bind and fix the logistics box. The hoisting process is time-consuming and labor-intensive.

[0006] Prior art 2, Chinese patent document with publication number CN109678049B (a box-shaped automatic gripping lifting device), uses a gripping claw as the lifting device. It achieves the gripping of goods through structures such as a top plate, an extension device, and a gripping device. However, its structure is relatively complex and has a higher possibility of failure. Summary of the Invention

[0030] Beneficial effects:

[0031] 1. Through the above technical solution, on the one hand, the vehicle-mounted logistics box hoisting connection structure of this application can realize the hoisting of the vehicle-mounted logistics box through the first connecting component and the second connecting component, without the need to set up other more complex structures or equipment such as gripping drive devices and gripping structures, which helps to simplify the hoisting structure and can reduce the failure rate of the hoisting structure to a certain extent; on the other hand, during the hoisting process, the vehicle-mounted logistics box hoisting connection structure of this application does not require manual binding operations, which can not only reduce the intensity and frequency of manual labor and reduce the risk of injury to operators during manual operation, but also improve hoisting efficiency, thereby helping to improve logistics transportation efficiency.

Simultaneously, the first and second connecting components... During the engagement of the connecting components, when the first connecting component is inserted into the receiving cavity of the second connecting component, the separator set in the receiving cavity will automatically switch the first connecting component to the first state (i.e., the second ends of the first and second abutting parts separate from each other), so that the first connecting component can be located in the receiving cavity and abut against the vehicle-mounted logistics box, allowing the crane arm to lift and transport the vehicle-mounted logistics box. In other words, the first and second connecting components of this application will automatically engage, that is, the first connecting component will automatically reach the first state when inserted into the receiving cavity of the second connecting component, without the need for manual binding or other manual operations.

[0053] The technical solution of this application will be described in detail below with reference to the accompanying drawings.

[0054] Example 1

[0055] like Figures 1 to 13 As shown, according to a first aspect of this application, a vehicle-mounted logistics box hoisting connection structure 103 is provided, including a first connecting component 1 and a second connecting component 2. The first connecting component 1 is used to be mounted on a boom 101. The first connecting component 1 includes a connecting body 11, a first abutment 12 and a second abutment 13. One end of the connecting body 11 is used to connect to the boom 101. The first ends of the first abutment 12 and the second abutment 13 are rotatably connected to the connecting body 11, and the second ends of the first abutment 12 and the second abutment 13 are configured to magnetically attract each other, wherein the first end is located below the second end. The second connecting component 2 is used to be mounted on a vehicle-mounted logistics box 102. The second connecting component 2 includes a receiving cavity 21 and a partition 22 disposed in the receiving cavity 21. The receiving cavity 21 is used for insertion of the first connecting component 1. The partition 22 is configured to separate the second ends of the first abutment 12 and the second abutment 13 when the first connecting component 1 is inserted into the receiving cavity 21.

[0056] The vehicle-mounted logistics box hoisting connection structure 103 includes a first state, in which the second ends of the first abutting member 12 and the second abutting member 13 are separated from each other and are respectively used to abut against the vehicle-mounted logistics box 102.

[0057] Through the above technical solution, on the one hand, the vehicle-mounted logistics box hoisting connection structure 103 of this application can realize the hoisting of the vehicle-mounted logistics box 102 through the first connecting component 1 and the second connecting component 2, without the need to set up other more complex structures or equipment such as gripping drive devices and gripping structures, which helps to simplify the hoisting structure and can reduce the failure rate of the hoisting structure to a certain extent; on the other hand, during the hoisting process, the vehicle-mounted logistics box hoisting connection structure 103 of this application does not require manual binding operations, which can not only reduce the intensity and frequency of manual labor and reduce the risk of injury to operators during manual operation, but also improve hoisting efficiency, thereby helping to improve logistics transportation efficiency.

[0058] Specifically, in this application, the vehicle-mounted logistics box hoisting connection structure 103 includes a first connecting component 1 and a second connecting component 2. The first connecting component 1 is mounted on the boom 101, and the second connecting component 2 is mounted on the vehicle-mounted logistics box 102. In the first state, the first abutting member 12 and the second abutting member 13 on the first connecting component 1 are both located within the receiving cavity 21 of the second connecting component 2 and abut against the vehicle-mounted logistics box 102. This allows the first connecting component 1 and the second connecting component 2 to cooperate with each other, enabling the boom 101 to lift and transport the vehicle-mounted logistics box 102. In other words, this application can achieve the hoisting of the vehicle-mounted logistics box 102 using the relatively simple first connecting component 1 and the second connecting component 2, which simplifies the hoisting structure and reduces the failure rate of the hoisting structure to a certain extent. Simultaneously, in the first connecting component 1 and... During the engagement of the second connecting component 2, when the first connecting component 1 is inserted into the receiving cavity 21 of the second connecting component 2, the partition 22 set in the receiving cavity 21 will automatically switch the first connecting component 1 to the first state (i.e., the second ends of the first abutting member 12 and the second abutting member 13 are separated from each other), so that the first connecting component 1 can be located in the receiving cavity 21 and abut against the vehicle logistics box 102, so that the boom 101 can lift and transport the vehicle logistics box 102. In other words, the first connecting component 1 and the second connecting component 2 of this application will automatically engage, that is, the first connecting component 1 will automatically reach the first state when it is inserted into the receiving cavity 21 of the second connecting component 2, without the need for manual binding or other manual operations. This not only helps to reduce the intensity and frequency of manual labor and reduce the risk of injury to operators during manual operation, but also improves the lifting efficiency, thereby improving the efficiency of logistics transportation.

[0059] It should be noted that, firstly, the boom 101 of this application can be any existing lifting device, which can be vehicle-mounted or fixed to the ground or other structures, as long as it can realize the lifting of the vehicle-mounted logistics container 102. This application does not make specific limitations in this regard. Secondly, the vehicle-mounted logistics container 102 of this application can also be any existing vehicle-mounted container (for accommodating goods), as long as it has space for installing the second connecting component 2 (of course, it should also have sufficient structural strength to facilitate lifting). This application does not make specific limitations in this regard either.

[0060] Furthermore, to facilitate a clearer understanding of the technical solution of this application by those skilled in the art, the working process / working principle of this application is described below:

[0061] First, a first connecting component 1 is installed on the boom 101 and a second connecting component 2 is installed on the vehicle-mounted logistics box 102. Then, when the vehicle-mounted logistics box 102 needs to be lifted, the boom 101 is controlled to move so that the first connecting component 1 is aligned with the entrance of the receiving cavity 21 of the second connecting component 2 and the first connecting component 1 is gradually inserted into the receiving cavity 21. During the insertion process, the partition 22 set in the receiving cavity 21 will separate the first abutting component 12 and the second abutting component 13 from each other. Then, the boom 101 is controlled to lift the first connecting component 1 so that the first abutting component 12 and the second abutting component 13 separated from each other on the first connecting component 1 abut against the vehicle-mounted logistics box 102 (i.e., against the top wall of the receiving cavity 21). At this time, the vehicle-mounted logistics box lifting connection structure 103 of this application has reached the first state, and the boom 101 can then be controlled to carry out the lifting operation.

[0062] It is understood that, in the above embodiments, the insertion depth of the first connecting component 1 into the receiving cavity 21 can be set by a program (for example, by setting the downward movement height of the boom 101 to a certain value to control the insertion depth), or a contact sensor can be used to identify the contact state between the first connecting component 1 and the bottom wall of the receiving cavity 21 to control the insertion depth of the first connecting component 1. This application does not specifically limit this.

[0063] In one embodiment of this application, such as Figures 4 to 6 , Figures 9 to 11 As shown, the first connecting component 1 of this application may further include a driving member 14, which is connected to the connecting body 11 to drive the connecting body 11 to rotate. The first abutment 12 and the second abutment 13 are respectively formed with a first guide surface 121 and a second guide surface 131. The second connecting component 2 further includes a third guide surface 23 and a fourth guide surface 24. The first guide surface 121 and the third guide surface 23 are matched with each other, and the second guide surface 131 and the fourth guide surface 24 are matched with each other. The third guide surface 23 and the fourth guide surface 24 are respectively configured to provide guidance for the first guide surface 121 and the second guide surface 131 when the connecting body 11 rotates, so that the first ends of the first abutment 12 and the second abutment 13 can attract each other. The vehicle-mounted logistics box hoisting connection structure 103 also includes a second state. In the second state, the second ends of the first abutment 12 and the second abutment 13 are magnetically attracted to each other, so that the second ends of the first abutment 12 and the second abutment 13 are attached to each other.

[0064] Thus, after the vehicle-mounted logistics box 102 is hoisted to a preset position (e.g., on the cargo platform of the vehicle 100 or in the unloading area of ​​the warehouse), the connecting body 11 can be rotated by the drive component 14. During the rotation of the connecting body 11, the first guide surface 121 on the first abutment 12 rotates under the guidance of the third guide surface 23 of the second connecting component 2. At the same time, the second guide surface 131 on the second abutment 13 rotates under the guidance of the fourth guide surface 24 of the second connecting component 2, so that the first abutment 12 and the second abutment 13 can rotate to a vertical state (i.e., based on the first state, rotate 90 degrees in the vertical direction with the first end of both as the axis of rotation). In other words, the second ends of the first abutment 12 and the second abutment 13 can come close to each other and stick together under the magnetic attraction.

[0065] In this way, the first abutment 12 and the second abutment 13 can automatically return from the first state to the state before insertion without manual operation, so that the first connecting component 1 and the second connecting component 2 can be disengaged from each other, and then the next vehicle-mounted logistics box 102 can be hoisted. This helps to reduce the intensity and frequency of manual labor, reduce the risk of injury to operators when operating manually, and also improve hoisting efficiency, thereby improving logistics transportation efficiency.

[0066] In one embodiment of this application, such as Figures 4 to 8 As shown, the connecting body 11 of this application may include a first part 111, which is formed as a columnar structure with an isosceles triangle cross-section. The two sides of the first part 111 corresponding to the two base angles of the isosceles triangle are respectively used to hinge with the first ends of the first abutment 12 and the second abutment 13. The two sides of the first part 111 corresponding to the legs of the isosceles triangle are respectively used to abut with the first abutment 12 and the second abutment 13. The second ends of the first abutment 12 and the second abutment 13 are disposed above the first part 111. A receiving cavity 1111 is formed in the first part 111, and the receiving cavity 1111 is interconnected with the first part 1111. The accommodating cavity 1112 is a limiting cavity, and the moving block 1113 is accommodated in the accommodating cavity 1111. One end of the accommodating cavity 1111 is connected to the side of the first part 111 corresponding to the base of the isosceles triangle, and the other end of the accommodating cavity 1111 is connected to the two sides of the first part 111 corresponding to the vertex of the isosceles triangle. The moving block 1113 includes a moving body 1113a and a limiting block 1113b. One end of the limiting block 1113b is connected to the bottom of the moving body 1113a. The shape of the moving body 1113a matches the accommodating cavity 1111, and the shape of the limiting block 1113b matches the limiting cavity 1112.

[0067] The separator 22 is used to abut against the moving body 1113a, which is configured to be abutted by the separator 22 and move upward within the receiving cavity 1111 to insert between the second ends of the first abutting member 12 and the second abutting member 13, so that the second ends of the first abutting member 12 and the second abutting member 13 are separated from each other.

[0068] Thus, on the one hand, the first part 111 provided in this application allows the first abutment 12 and the second abutment 13 to have sufficient contact area and provides a certain degree of support for them, enabling them to form a relatively stable magnetic attraction. On the other hand, since the two sides of the two base angles of the isosceles triangle corresponding to the first part 111 are respectively used to hinge with the first ends of the first abutment 12 and the second abutment 13, and the two sides of the waist of the isosceles triangle corresponding to the first part 111 are respectively used to abut with the first abutment 12 and the second abutment 13, and the second ends of the first abutment 12 and the second abutment 13 are located above the first part 111, the magnetic attraction between the first abutment 12 and the second abutment 13 is weakened when the first connecting assembly 1 is inserted into the receiving cavity 21. This allows the first abutment 12 and the second abutment 13 to rotate to the first state under their own weight, facilitating lifting.

[0069] Meanwhile, in this embodiment, the movable block 1113, as configured, can move upward under the action of the separator 22, and thus can be inserted between the first abutment 12 and the second abutment 13, thereby weakening the magnetic attraction at the second ends of the first abutment 12 and the second abutment 13, allowing them to separate under the action of gravity. Furthermore, through the cooperation of the limiting block 1113b and the limiting cavity 1112, the movable block 1113 can be confined within the receiving cavity 1111.

[0070] Furthermore, to facilitate a clearer understanding of the technical solutions of this application by those skilled in the art, the working process / working principle of the connecting body 11 in the above embodiments is described below:

[0071] During the process of inserting the first connecting component 1 into the second connecting component 2, the separator 22 first abuts against the moving block 1113. As the first connecting component 1 moves downward, the moving block 1113 gradually moves upward until it is inserted between the first abutting block and the second abutting block, thus separating the two. During the upward movement of the first connecting component 1 (during the process of reaching the first state, that is, during the process of the first abutting component 12, the second abutting component 13 abutting against the vehicle logistics box 102), the moving block 1113 automatically returns to its original position under the action of gravity.

[0072] In one embodiment of this application, such as Figure 4and Figure 5 As shown, the connecting body 11 of this application may further include a second part 112, which is connected to the bottom surface of the first part 111. In the vertical direction, the projection of the second part 112 is located within the projection of the first part 111, so that the bottom of the connecting body 11 can form an avoidance notch 113. In the first state, the first ends of the first abutting member 12 and the second abutting member 13 are respectively located in the avoidance notch 113 and abut against the connecting body 11.

[0073] In this way, in the first state, the first abutting member 12 and the second abutting member 13 can form a stable abutting relationship with the connecting body 11, which is conducive to improving the positional stability of the first abutting member 12 and the second abutting member 13, and thus also conducive to the crane arm 101 being able to lift the vehicle logistics box 102 more stably.

[0074] In one embodiment of this application, such as Figures 4 to 8 As shown, the connecting body 11 of this application may further include two connecting rods 114 arranged opposite to each other, a connecting plate 115 and a connecting post 116. One end of each of the two connecting rods 114 is connected to the top of the first part 111, and the other end of each of the two connecting rods 114 is connected to the connecting plate 115. The side of the connecting plate 115 away from the connecting rods 114 is connected to one end of the connecting post 116, and the end of the connecting post 116 away from the connecting plate 115 is connected to the driving member 14. In the second state, the second ends of the first abutting member 12 and the second abutting member 13 are located between the two connecting rods 114.

[0075] Thus, on the one hand, the connecting rod 114, connecting plate 115, and connecting column 116 configured in this way can transmit the load more stably (i.e., can transmit the gravity of the vehicle-mounted logistics box 102 to the boom 101 more stably), so that the vehicle-mounted logistics box 102 can be lifted more stably. On the other hand, the driving member 14 configured in this way can reliably control the rotation angle of the connecting body 11, so that the vehicle-mounted logistics box lifting connection structure 103 of this application can reliably switch between the first state and the second state.

[0076] In one embodiment of this application, such as Figure 4As shown, the second end of the first abutment member 12 of this application may include a first plane 122 near the second abutment member 13, and the second end of the second abutment member 13 includes a second plane 132 near the first abutment member 12. A first magnetic suction member 1221 is provided on the first plane 122, and a second magnetic suction member 1321 that matches the first magnetic suction member 1221 is provided on the second plane 132. In the first state, the first plane 122 and the second plane 132 are located in the receiving cavity 21 and are respectively used to abut against the vehicle logistics box 102 so that the boom 101 can be used to lift the vehicle logistics box 102. In the second state, the first magnetic suction member 1221 and the second magnetic suction member 1321 are in magnetic contact with each other so that the second ends of the first abutment member 12 and the second abutment member 13 can fit together.

[0077] Thus, in this embodiment, the first plane 122 and the second plane 132 respectively enable the first abutting member 12 and the second abutting member 13 to form a relatively stable abutting relationship with the vehicle-mounted logistics box 102, so that the vehicle-mounted logistics box 102 can be lifted and transported relatively stably.

[0078] It is understood that the first magnetic member 1221 and the second magnetic member 1321 of this application can have various structural forms. For example, in one embodiment, such as Figure 4 As shown, the first magnetic suction member 1221 and the second magnetic suction member 1321 can be formed into corresponding strip structures, and the first magnetic suction member 1221 is disposed on the side of the second end of the first abutment member 12 near the second abutment member 13 (correspondingly, the second magnetic suction member 1321 is disposed on the side of the second end of the second abutment member 13 near the first abutment member 12). That is, in the second state, the first magnetic suction member 1221 and the second magnetic suction member 1321 are located at the bottom of the second end, so that when the separator 22 or the moving block 1113 in the above embodiment is inserted between the first abutment member 12 and the second abutment member 13, the first abutment member 12 and the second abutment member 13 can be separated from each other more easily.

[0079] In another embodiment, the first magnetic member 1221 and the second magnetic member 1321 may also be formed as plate-like structures adapted to the first plane 122 and the second plane 132, respectively.

[0080] It is understood that, in one embodiment of this application, one of the first magnetic attractor 1221 and the second magnetic attractor 1321 can be formed as a magnetic plate or a magnetic strip, and the other of the first magnetic attractor 1221 and the second magnetic attractor 1321 can be formed as an iron plate or an iron strip. In another embodiment of this application, the first magnetic attractor 1221 and the second magnetic attractor 1321 can be configured as two mutually attractive magnetic plates or magnetic strips.

[0081] In one embodiment of this application, such as Figure 4 , Figure 5 , Figures 9 to 11 As shown, the first guide surface 121 and the second guide surface 131 of this application can be formed into a triangular planar structure, and the third guide surface 23 and the fourth guide surface 24 can be formed into a curved structure; wherein, in the first state, the height of the first guide surface 121 and the second guide surface 131 is less than the height of the connecting body 11.

[0082] Thus, on the one hand, the first guide surface 121 and the second guide surface 131 are formed into a triangular plane, and in the first state, the height of the first guide surface 121 and the second guide surface 131 is less than the height of the connecting body 11, which can reduce the setting area and space occupied by the first guide surface 121 and the second guide surface 131. This is beneficial to reduce the degree of weight reduction of the first abutment 12 and the second abutment 13 caused by setting the first guide surface 121 and the second guide surface 131, so that the first abutment 12 and the second abutment 13 can automatically switch to the first state under the action of sufficient gravity. On the other hand, the third guide surface 23 and the fourth guide surface 24 are set as curved structures, which not only helps the first abutment 12 and the second abutment 13 to automatically switch to the second state under the guidance of the third guide surface 23 and the fourth guide surface 24 respectively, but also reduces the friction between the first abutment 12, the second abutment 13, the third guide surface 23 and the fourth guide surface 24, thereby reducing the wear of these four components and thus helping to improve the service life of the first abutment 12, the second abutment 13, the third guide surface 23 and the fourth guide surface 24.

[0083] According to a second aspect of this application, a lifting system is provided, including a boom 101, a vehicle-mounted logistics box 102, and a vehicle-mounted logistics box lifting connection structure 103 according to any one of the technical solutions in the first aspect of this application, wherein a first connecting component 1 is disposed on the boom 101, and a second connecting component 2 is disposed on the vehicle-mounted logistics box 102.

[0084] Thus, on the one hand, the hoisting system of this application can hoist the vehicle-mounted logistics box 102 through the first connecting component 1 and the second connecting component 2, without the need for additional gripping drive devices, gripping structures or other more complex structures or equipment, which helps to simplify the hoisting structure and can reduce the failure rate of the hoisting structure to a certain extent; on the other hand, during the hoisting process, the hoisting system of this application does not require manual binding or other operations, which can not only reduce the intensity and frequency of manual labor and reduce the risk of injury to operators during manual operation, but also improve hoisting efficiency, thereby helping to improve logistics transportation efficiency.

[0085] According to a third aspect of this application, a vehicle 100 is provided, the vehicle 100 including a vehicle body 104 and a lifting system according to a second aspect of this application, wherein a boom 101 is disposed on the vehicle body 104, and the vehicle body 104 is used to carry a vehicle-mounted logistics container 102.

[0086] Thus, the vehicle 100 of this application has the crane 101 mounted on the vehicle body 104, which can move with the vehicle to the destination. The crane 101 can be used to directly load and unload the vehicle-mounted logistics box 102, which is conducive to improving transportation efficiency.

[0087] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
