[0044] At present, in outdoor unmanned vehicle traction operations, the material truck and the tractor usually communicate by radio communication. However, wireless communication is difficult to implement for data transmission. When outdoor conditions are relatively bad, such as thunderstorms, the transmission signal is easily interfered, resulting in transmission delays or interruptions.

[0045] In view of this, the present invention provides a wireless communication component for unmanned traction operation of a material truck and a tractor, aiming to solve the problem that the existing radio communication method is easily interfered. Figures 1 to 4 A schematic structural diagram of an embodiment of a wireless communication component provided by the present invention.

[0046] See also Figures 1 to 4 The wireless communication component 100 includes a fixing device 1 and an optical communication device 2. The fixing device 1 includes a material cart mounting seat 11 and a tractor mounting seat 12. The material cart mounting seat 11 is used to be installed on the material cart, and the tractor mounting seat 12 is used to be installed on the tractor. The optical communication device 2 includes an optical signal transmitter 21 and an optical signal receiver 22 that communicate with each other. One of the optical signal transmitter 21 and the optical signal receiver 22 is arranged on the material cart mounting seat 11, and the other is arranged on the tractor mounting seat 12.

[0047] In the technical solution of the present invention, the material cart mounting seat 11 and the tractor mounting seat 12 are used to help install the optical communication device on the material cart and the tractor respectively, so that the material cart and the tractor can communicate with each other. At the same time, the optical signal transmitter 21 and the optical signal receiver 22 are used to utilize light beams for data transmission, which can effectively avoid electromagnetic interference and prevent signal interruption, help to continuously transmit data and improve the continuity of communication, and can quickly transmit data, which can effectively improve the data transmission rate and help avoid the problem of data transmission delay.

[0048] It should be noted that there are various ways to connect the material cart mounting seat 11 to the material cart. The material cart mounting seat 11 can be fixedly mounted on the material cart by welding, or can be detachably fixed to the material cart by bolts, etc. The present invention is not limited to this. Similarly, the tractor mounting seat 12 can be fixedly mounted on the tractor, or can be detachably mounted on the tractor, etc.

[0049] Furthermore, since the tractor may need to turn, go uphill or downhill, etc. when towing the material vehicle, and the light beam propagates in a straight line, the optical signal transmitter 21 may be disconnected from the optical signal receiver 22. In view of this, in this embodiment, the wireless communication component 100 also includes a movable connection structure 3, and the movable connection structure 3 includes a support column 31, a movable part 32 and a driving part 33. The support column 31 is arranged on the material vehicle mounting seat 11, and the support column 31 is extended up and down. The movable part 32 is movably installed on the support column 31. The driving part 33 is arranged on the tractor mounting seat 12, and is used to drive the movable part 32 to move, wherein the optical signal transmitter 21 or the optical signal receiver 22 is arranged on the movable part 32. In this way, the movable part 32 is driven by the driving part 33 to move along the support column 31, so as to drive the optical signal transmitter 21 or the optical signal receiver 22 to rotate with the tractor, so that the optical communication device 2 can adapt to the movement of the tractor, so as to ensure that the optical communication device 2 is always in a connected state, thereby preventing communication interruption during traction.

[0050] Furthermore, when the tractor turns the material cart, in order to avoid communication interruption, in the present embodiment, the movable part 32 is rotatably installed on the support column 31 along the up-down axis. When the tractor turns, the driving part 33 drives the movable part 32 to rotate around the support column 31, so as to drive the optical signal transmitter 21 or the optical signal receiver 22 provided on the movable part 32 to rotate simultaneously with the tractor, so that the optical signal transmitter 21 is always in a connected state with the optical signal transmitter 21, thereby helping to avoid communication interruption.

[0051] Furthermore, there are multiple ways to drive the movable part 32 to rotate, which may be driven by a magnetic connection structure, or by connecting the optical signal transmitter 21 to the optical signal transmitter 21 by bolts to drive the movable part 32 to rotate, etc. Specifically, in the present embodiment, the driving part 33 includes a driving groove 331 formed on the end surface of the tractor mounting seat 12 facing the material vehicle mounting seat 11, and the driving groove 331 is adapted to the movable part 32 to drive the movable part 32 to rotate when the tractor rotates. In this way, the driving groove 331 is used to drive the movable part 32 in the driving groove 331 to rotate when the tractor rotates, so as to ensure that the optical signal transmitter 21 and the optical signal transmitter 21 are always in a connected state.

[0052] Furthermore, in the direction from the material cart toward the tractor, the width of the movable part 32 is reduced, and correspondingly, the width of the driving groove 331 is reduced. With such a configuration, on the one hand, when the tractor is docked with the material cart, the movable part 32 can be guided to be inserted into the driving part 33 to ensure that the optical signal transmitter 21 and the optical signal receiver 22 are aligned; on the other hand, the movable part 32 is tightly fitted with the driving part 33 to avoid the movable part 32 from rotating relative to the driving part 33, so as to ensure that when the tractor turns, the movable part 32 can be driven to rotate.

[0053] After the traction operation is completed, the material cart will be separated from the tractor. At this time, the movable part 32 will be at any angle, which is not conducive to alignment during the next traction. For this reason, in the present embodiment, the movable connection structure 3 includes a position centering structure 34 provided between the material cart mounting seat 11 and the movable part 32. The position centering structure 34 is used to make the movable part 32 rotate to the middle of the mounting seat when the material cart is separated from the tractor. In this way, through the position centering structure 34, when the material cart is separated from the tractor, the movable part 32 is always in the middle of the mounting seat, thereby ensuring that the movable part 32 is in a certain position for alignment during the next traction, thereby helping to avoid the failure of the optical communication device to connect due to the uncertain position of the movable part 32.

[0054] It should be noted that there are various forms of the position centering structure 34 . The position centering structure 34 may be positioned by a magnetic connection structure or by a spring, etc., and the present invention does not limit this.

[0055] Furthermore, the position centering structure 34 includes a first elastic member 341 with two ends respectively disposed on the material cart mounting seat 11 and the movable portion 32. In this configuration, when the material cart is separated from the tractor, the movable portion 32 is always located in the middle of the mounting seat through the first elastic member 341. It is understandable that the first elastic member 341 can be rubber or a spring.

[0056] It should be noted that the first elastic member 341 can be fixedly mounted on the trolley mounting seat 11 and / or the movable portion 32, or can be detachably mounted on the trolley mounting seat 11 and / or the movable portion 32, and the present invention is not limited to this.

[0057] Furthermore, the position centering structure 34 also includes two lifting eye bolts 342, and the two lifting eye bolts 342 are respectively arranged on the material cart mounting seat 11 and the movable part 32, wherein the first elastic member 341 is arranged between the two lifting eye bolts 342. In this way, by setting the lifting eye bolts 342, the position centering structure 34 can be detachably installed on the material cart mounting seat 11 and the movable part 32 to facilitate maintenance and replacement.

[0058] Since light propagates in a straight line, when the tractor pulls the material cart uphill or downhill, there is a height difference between the material cart and the tractor, causing the optical signal transmitter 21 to be disconnected from the optical signal receiver 22. In view of this, in the present embodiment, the movable part 32 is installed on the support column 31 in a straight line along the up and down direction. When the tractor goes uphill or downhill, the movable part 32 is driven by the driving part 33 to move up and down along the support column 31, so as to drive the optical signal transmitter 21 or the optical signal receiver 22 provided on the movable part 32 to move up and down along with the tractor, so that the optical signal transmitter 21 is always connected with the optical signal transmitter 21, thereby helping to avoid communication interruption.

[0059] It should be noted that when the tractor tows the material cart to turn, the driving part 33 can drive the movable part 32 to rotate around the support column 31, so as to drive the optical signal transmitter 21 or the optical signal receiver 22 to rotate with the tractor, so that the optical communication device 2 is always in a connected state; when the tractor tows the material cart uphill or downhill, the driving part 33 can drive the movable part 32 to move up and down along the support column 31, so as to drive the optical signal transmitter 21 or the optical signal receiver 22 to move up and down with the tractor, so that the optical communication device 2 is always in a connected state. In this way, through the support column 31, the movable part 32 can both rotate and move up and down, so that the optical communication device 2 can adapt to the movement of the tractor, thereby helping to avoid communication interruption during traction.

[0060] Furthermore, the movable part 32 is provided with a mounting hole 321 for the support column 31 to pass through, and the movable connection structure 3 includes a driving rod 35 provided on the movable part 32, and the driving rod 35 is downwardly abutted against the driving part 33 so that the driving part 33 can drive the movable part 32 to move. When the tractor goes uphill, the driving rod 35 drives the movable part 32 to move upward to drive the optical signal transmitter 21 or the optical signal receiver 22 to move upward with the tractor, so that the optical communication device 2 is at the same height, so that the optical communication device 2 is always in a connected state. When the tractor shifts downward, the movable part 32 drives the optical signal transmitter 21 or the optical signal receiver 22 to move downward with the tractor under the action of gravity, so that the optical communication device 2 is at the same height, so that the optical communication device 2 is always in a connected state.

[0061] It should be noted that, in order to enable the movable part 32 to move downward with the tractor, in one embodiment, the movable part 32 is made of metal to increase the weight of the movable part 32 to ensure that the movable part 32 can move downward with the tractor. Of course, in other embodiments, a spring may also be provided between the movable part 32 and the material cart mounting seat 11 to enable the movable seat to move downward.

[0062] Furthermore, the mounting hole 321 includes a first hole section and a second hole section which are arranged in steps along the up-down direction, the aperture of the first hole section is larger than the aperture of the second hole section to form an upwardly arranged limiting step surface, and the movable connection structure 3 also includes a limiting plate 36 arranged at the upper end of the support column 31, the limiting plate 36 abuts against the limiting step surface to limit the movable stroke of the movable part 32. In this way, the movable stroke of the movable part 32 along the up-down direction is limited by the matching limiting plate 36 and the limiting step surface, so as to prevent the movable part 32 from being separated from the support column 31.

[0063] Furthermore, the movable connection structure 3 also includes a wear-resistant sleeve 37 arranged between the movable part 32 and the support column 31. By setting up the wear-resistant sleeve 37, the wear between the support column 31 and the movable part 32 is reduced, and damage to the support column 31 or the movable part 32 is avoided, thereby helping to increase the service life of the movable connection structure 3.

[0064] It should be noted that there are various installation forms of the wear-resistant sleeve 37. The wear-resistant sleeve 37 can be fixedly installed on the movable part 32 or the support column 31, or the wear-resistant sleeve 37 can be detachably installed on the movable part 32 or the support column 31, etc. The present invention does not limit this.

[0065] Theoretically, the driving rod 35 can be one or more. Specifically, in the present embodiment, two driving rods 35 are provided, and the two driving rods 35 are spaced apart in the left-right direction. With such a configuration, on the one hand, the driving rods 35 are symmetrically arranged on both sides of the movable part 32, so as to facilitate the upward movement driven by the driving part 33 to avoid the movable part 32 from getting stuck during movement. On the other hand, the driving rods 35 can avoid the optical communication device 2 to avoid blocking the optical communication device 2.

[0066] Furthermore, since no guiding structure is provided between the movable part 32 and the support column 31, when the axis of the driving rod 35 deviates from the axis of the support column 31, a torque is generated when the movable part 32 moves up and down along the support column 31, so that the friction between the movable part 32 and the support column 31 increases, resulting in the movable part 32 and the support column 31 being stuck. In view of this, in the present embodiment, the axis of the driving rod 35 is adjacent to the axis of the support column 31 along the front-to-back direction. Such arrangement is used to reduce the torque between the driving rod 35 and the support column 31, so that the movable part 32 only moves in the up-and-down direction, thereby avoiding the movable part 32 and the support column 31 from being stuck.

[0067] In order to prevent the movable part 32 and the driving part 33 from being damaged when docking, in the present embodiment, the movable connection structure 3 also includes a second elastic member 38, and the second elastic member 38 is arranged between the movable part 32 and the driving part 33. In this way, the movable part 32 and the driving part 33 form elastic contact when docking through the second elastic member 38, so as to prevent the movable part 32 and the driving part 33 from being damaged due to hard contact.

[0068] It is understandable that the second elastic member 38 may be made of rubber or polyurethane, etc., and the present invention is not limited to this.

[0069] In order to prevent the optical communication device from getting wet, in the present embodiment, the optical communication device 2 includes two waterproof covers 4 respectively arranged on the material vehicle mounting seat 11 and the tractor mounting seat 12, and the two waterproof covers 4 are respectively arranged corresponding to the optical signal transmitter 21 and the optical signal receiver 22. In this way, the optical signal transmitter 21 and the optical signal receiver 22 are respectively sealed by the two waterproof covers 4 to prevent the optical signal transmitter 21 and the optical signal receiver 22 from being damaged due to water ingress.

[0070] It should be noted that the waterproof cover 4 has various forms. The waterproof cover 4 can be a fully enclosed type or a semi-enclosed type, etc., and the present invention does not limit this.

[0071] Furthermore, when the waterproof cover 4 is fully enclosed, in order to avoid affecting the optical communication device, in the present embodiment, the waterproof cover 4 is made of a transparent material. The transparent material is used to allow the light beam to enter and exit the optical signal transmitter 21 and the optical signal receiver 22, thereby avoiding the waterproof cover 4 affecting the optical communication device 2.

[0072] The above description is only a preferred embodiment of the present invention, and does not limit the patent scope of the present invention. All equivalent structural changes made by using the contents of the present invention specification and drawings under the concept of the present invention, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
