Description

Technical Field

[0001] This application claims priority to a Chinese patent application with application number 202110291934.5 filed with the Chinese Patent Office on March 18, 2021, and all the contents of the application are incorporated herein by reference.

[0002] This application relates to the field of logistics technology, for example, to sorting vehicles and sorting machines.

Background Art

[0003] The sorting vehicle includes a harness structure and a plurality of vehicle bodies connected in sequence. The vehicle body includes a chassis and a chain structure. One end of the chain structure is pivotally attached to the corresponding chassis, and the other end of the chain structure is pivotally attached to the adjacent chassis. The harness structure is connected to the chassis and extends along the arrangement direction of the plurality of vehicle bodies. The harness structure is connected to the driver of the sorting vehicle and can provide signals and power to the driver. When the sorting vehicle is at a curve position, the adjacent vehicle bodies are not in a straight line but are arranged at a certain angle, so the harness structure bends repeatedly, and the harness structure is prone to breakage, has a short lifespan, and the driving stability of the sorting vehicle and sorting machine to which the above structure is applied is poor.

[0004] Therefore, there is an urgent need for an application for a sorting vehicle and a sorting machine to solve the problems that the harness structure is prone to breakage and has a short lifespan, and the driving stability of the sorting vehicle and sorting machine is poor.

Modes for Carrying Out the Invention

[0011] Hereinafter, the present application will be described in detail with reference to the drawings and embodiments.

[0012] In the description of the present application, unless otherwise clearly defined and limited, the terms "connection", "coupling", and "fixation" should be understood in a broad sense. For example, it may be a fixed connection, a detachable connection, an integrally formed connection, a mechanical connection, an electrical connection, a direct connection, an indirect connection through an intermediate medium, or a relationship of communication inside two elements or interaction between two elements. Those skilled in the art can understand the specific meaning of the above terms in the present application according to the specific situation.

[0013] In the present application, unless otherwise clearly defined and limited, the fact that the first feature is "above" or "below" the second feature may include that the first feature is in direct contact with the second feature, or may include that the first feature and the second feature are not in direct contact but in contact through other features therebetween. Further, the fact that the first feature is "above", "upward" and "upper surface" of the second feature includes that the first feature is directly above and obliquely above the second feature, or simply means that the horizontal height of the first feature is higher than that of the second feature. The fact that the first feature is "below", "downward" and "lower surface" of the second feature includes that the first feature is directly below and obliquely below the second feature, or simply means that the horizontal height of the first feature is lower than that of the second feature.

[0014] In the description of this embodiment, the orientation or positional relationship of terms such as "above", "below", "left", and "right" is based on the orientation or positional relationship shown in the drawings, and is only for facilitating the description and simplifying the operation, and does not expressly or implicitly imply that the indicated device or element must have a specific orientation and be structured and operated in a specific orientation. Therefore, it should not be understood as limiting the present application. Also, the terms "first" and "second" are only for distinguishing in the description and have no special meaning.

[0015] As shown in FIG. 1, this embodiment provides a sorting machine 1000, which includes a sorting cart 100, a frame 300, a rail assembly 200, and a drive assembly. Both the rail assembly 200 and the drive assembly are attached to the frame 300. The sorting cart 100 is provided on the rail assembly 200, and the drive assembly drives the sorting cart 100 to move along the rail assembly 200.

[0016] As shown in FIG. 2, the sorting cart 100 includes a harness structure 2 and at least two sequentially connected vehicle bodies 1. The vehicle body 1 includes a chassis 11 and a chain structure 12. The chain structure 12 includes a first connecting frame 121, a roller 122, and a second connecting frame 123. The first connecting frame 121 is fixed to the chassis 11, the roller 122 is pivotally attached to the first connecting frame 121, one end of the second connecting frame 123 is pivotally attached to the first connecting frame 121 of the corresponding vehicle body 1, and the other end is pivotally attached to the first connecting frame 121 of the adjacent vehicle body 1. The rail assembly 200 is annular, and the roller 122 operates along the annular rail assembly 200. The harness structure 2 is respectively connected to two adjacent vehicle bodies 1. The harness structure 2 is electrically connected to the driver 13 of the vehicle body 1, and the harness structure can provide signals and power to the driver. When the sorting cart 100 is at a curved position, the adjacent vehicle bodies 1 are not in a straight line and are arranged at a certain angle. Therefore, the harness structure 2 bends repeatedly, the harness structure 2 is prone to breakage, has a short lifespan, and the operating stability of the sorting cart 100 and the sorting machine 1000 to which the above structure is applied is poor.

[0017] To solve the above problems, as shown in FIGS. 2 and 3, the harness structure 2 of this embodiment is respectively connected to two adjacent vehicle bodies 1. The harness structure 2 includes an elastic deformation portion, and the elastic deformation portion is located at the joint position of two adjacent vehicle bodies 1. When the sorting vehicle 100 is at a curve position, the elastic deformation portion at the curve position elastically deforms, so as to realize dispersing the bending force in the harness structure 2 to the elastic deformation portion, avoiding folding the harness structure 2 hard, ensuring the service life of the harness structure 2, and improving the driving stability of the sorting vehicle 100 and the sorting machine 1000.

[0018] Exemplarily, as shown in FIG. 2, the elastic deformation portion is a spiral structure. When two adjacent vehicle bodies 1 form a certain angle, the spiral structure can bend and deform greatly, realizing a large bending of the angle change of the sorting vehicle 100.

[0019] Preferably, the harness structure 2 includes a wire core and an elastic sheath. The elastic sheath is coated on the outer periphery of the wire core. The elastic sheath can improve the elastic deformation ability of the spiral structure, and the spiral structure can adapt to a greater degree of elastic deformation. Exemplarily, the elastic sheath can be made of polyvinyl chloride, polypropylene, etc. Here, the elastic sheath adopts a polypropylene material, which is non-toxic, odorless, has a small density, high strength, high hardness, and effectively ensures that the signal cable has a highly stretchable spiral structure. The elastic sheath made of polypropylene has an elastic deformation ability 4 to 5 times higher than that of the elastic sheath made of polyvinyl chloride.

[0020] The structure of the harness structure 2 will be described with reference to FIG. 2. As shown in FIG. 2, the vehicle body 1 includes a driver 13, and the harness structure 2 includes a communication harness 21. Two first connection portions 212 of the communication harness 21 are respectively connected to the drivers 13 in two adjacent vehicle bodies 1, realizing the transmission of signals between the vehicle body 1 and the vehicle body 1, and the communication harness 21 can realize the transmission of signals of the vehicle body 1.

[0021] If the entire harness structure 2 is processed into a screw shape, the fixation between the harness structure 2 and the vehicle body 1 will become weak, and the harness structure 2 will be prone to falling off the vehicle body 1. To solve the above problem, as shown in FIG. 2, the communication harness 21 includes a first elastic deformation portion 211 and first connection portions 212 provided at both ends of the first elastic deformation portion 211. The first elastic deformation portion 211 is located at the joint position of two adjacent vehicle bodies 1. The first connection portion 212 includes a first straight segment, and the two first straight segments are respectively fixed to two adjacent vehicle bodies 1. Since the structure of the first straight segment is flatter than the screw shape, it is easy to realize the fixation with the vehicle body 1, and good fixation between the harness structure 2 and the vehicle body 1 can be ensured.

[0022] As shown in FIG. 2, the harness structure 2 further includes a conductive harness 22. The conductive harness 22 includes a second elastic deformation portion 221 and second connection portions 222 provided at both ends of the second elastic deformation portion 221. The second elastic deformation portion 221 is located at the joint position of two adjacent vehicle bodies 1. The two second connection portions 222 are respectively fixed to two adjacent vehicle bodies 1. Preferably, the second connection portion 222 includes a second straight segment, and the two second straight segments are respectively fixed to two adjacent vehicle bodies 1. Since the structure of the second straight segment is flatter than the screw shape, it is easy to realize the fixation with the vehicle body 1, and good fixation between the conductive harness 22 and the vehicle body 1 can be ensured.

[0023] As shown in FIG. 2, there are at least three vehicle bodies. The sorting vehicle further includes a splitter 4, a sub-wire 5 and a power source. A splitter 4 is provided on each vehicle body 1. The splitter 4 and the corresponding driver 13 are connected via a sub-wire 5. The splitter 4 of the middle vehicle body 1 is connected to the second connection portions 222 of two adjacent conductive harnesses 22. The splitter 4 of the vehicle body 1 at the end is respectively connected to the power source and the second connection portions 222 of the adjacent conductive harness 22, so as to realize power supply to different drivers 13 of the power source.

[0024] The sorting vehicle 100 further includes a fixing structure 3. To facilitate understanding of the structure of the fixing structure 3, as shown in FIG. 4, the fixing structure 3 includes a mounting plate 31, a wire holder 32, and a fixture 33. The mounting plate 31 is provided on the vehicle body 1. The wire holder 32 clamps the first straight segment and the second straight segment together with the mounting plate 31. The fixture 33 fixes the mounting plate 31 and the wire holder 32. Thereby, the fixing structure 3 realizes the function of fixing the harness structure 2 to the vehicle body 1. During the operation of the sorting vehicle 100, it avoids the harness structure 2 from falling off the vehicle body 1 and ensures the normal operation of the sorting vehicle 100. In order to realize a strong connection between the harness structure 2 and the vehicle body 1, in this embodiment, the wire holder 32 is in a block shape. Since the strength and hardness of the block-shaped wire holder 32 are greater, it realizes the function of firmly clamping the first straight segment and the second straight segment together with the mounting plate 31. Exemplarily, the fixture 33 may be a screw or a pin, etc.

[0025] As a preferred form, as shown in FIG. 5, a receiving groove is opened in the wire holder 32. The first straight segment and the second straight segment are received in the receiving groove, realizing the function of quickly attaching and positioning the first straight segment and the second straight segment to the wire holder 32 respectively, and improving the attachment efficiency of the harness structure 2, the fixing structure 3, and the vehicle body 1. Exemplarily, the wire pressing block 32 is respectively provided with an independent first receiving groove 321 and a second receiving groove 324. Here, the shape and size of the first receiving groove 321 respectively match the first straight segment, and the shape and size of the second receiving groove 324 respectively match the second straight segment, realizing the physical isolation between the communication harness 21 and the conductive harness 22, preventing signal interference between the communication harness 21 and the conductive harness 22, and ensuring that both the communication harness 21 and the conductive harness 22 can operate normally.

[0026] In a preferred embodiment, a receiving groove is formed on the lower end surface of the wire retainer 32, a vertical groove communicating with the receiving groove is formed on the side surface of the wire retainer 32, and the bottom surface of the receiving groove and the bottom surface of the vertical groove are connected via an arc transition surface. Exemplarily, as shown in FIG. 5, a first receiving groove 321 and a second receiving groove 324 are formed on the lower end surface of the wire retainer 32, a first vertical groove 322 and a second vertical groove 325 are formed on the side surface of the wire retainer 32, the first vertical groove 322 communicates with the first receiving groove 321, and the second vertical groove 325 communicates with the second receiving groove 324. The bottom surface of the first receiving groove 321 and the bottom surface of the first vertical groove 322 are connected via a first arc transition surface 323, the bottom surface of the second receiving groove 324 and the bottom surface of the second vertical groove 325 are connected via a second arc transition surface 326, and the first arc transition surface 323 and the second arc transition surface 326 can reduce stress concentration in the first straight segment and the second straight segment, avoid breakage of the first straight segment and the second straight segment, and improve the service life of the communication harness 21 and the conductive harness 22.

[0027] In a preferred embodiment, the first straight segment and the second straight segment can generate a certain amount of elastic deformation. Since the depth of the first receiving groove 321 is 1 mm to 2 mm smaller than the diameter of the first straight segment and the depth of the second receiving groove 326 is 1 mm to 2 mm smaller than the diameter of the second straight segment, when the fixing structure 3 fixes the first straight segment and the second straight segment to the vehicle body 1, the wire retainer 32 can, together with the mounting plate 31, tightly sandwich the communication harness 21 and the conductive harness 22.
