Description

Technical Field

[0001] This utility model relates to the field of AGV trolley accessories technology, and in particular to a current collector support structure in a sliding line system. Background Technology

[0002] In fields such as automated equipment, electronic equipment, and palletizing and transfer equipment, the movement of equipment is often limited to the layout of sliding line systems, such as AGV trolleys.

[0003] In existing technologies, hubs are directly fixed to mobile devices. Since the displacement trajectory of mobile devices is non-linear, hubs cannot automatically adapt to the movement trajectory of mobile devices, thus limiting the working range of the equipment. Furthermore, when mobile devices need to perform linear, circular, or reciprocating movements, the current collector in the sliding rail system also needs to perform corresponding actions within the sliding rail groove, which greatly affects the stability of the current collector's operation and shortens its service life, significantly impacting production.

[0004] Therefore, the existing mobile device hubs suffer from technical problems due to their unreasonable installation structure. Summary of the Invention

[0005] The purpose of this utility model is to overcome the defects of the prior art and provide a current collector support structure for a sliding line system.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A current collector support structure in a slide rail system includes a mounting base;

[0008] A linkage arm, which is rotatably connected to the mounting base;

[0009] A floating plate, which is mounted on the connecting arm;

[0010] A floating assembly, wherein the floating plate is mounted on the link arm via the floating assembly, and the floating plate floats relative to the link arm within a preset range via the floating assembly;

[0011] A current collector is disposed on the floating plate.

[0012] Preferably, the mounting base is provided with a rotating shaft;

[0013] The rotating shaft is rotatably connected to the mounting base, and the connecting rod arm is rotatably connected to the mounting base via the rotating shaft.

[0014] Preferably, a bearing is provided between the rotating shaft and the mounting base.

[0015] Preferably, the bearing is a deep groove ball bearing.

[0016] Preferably, there are at least two bearings, and at least two bearings are arranged along the length direction of the shaft.

[0017] Preferably, the floating component includes an elastic block, which is mounted on the linkage arm;

[0018] A floating shaft, which is fixed to the elastic block, and a floating plate sleeved on the floating shaft;

[0019] And an elastic element, one end of which abuts against the elastic block, and the other end of which abuts against the floating plate.

[0020] Preferably, the elastic element is sleeved on the floating shaft.

[0021] Preferably, the elastic element is a compression spring.

[0022] Preferably, the pivot of the connecting arm is perpendicular to the length direction of the connecting arm.

[0023] Preferably, the connecting arm is also provided with a tension spring.

[0024] The advantages of this utility model compared with the prior art are:

[0025] This invention connects the linkage arm to the mounting base in a rotatable manner, and the current collector is mounted on the linkage arm, so that the current collector can rotate 360° without jamming in the plane formed by the running trajectory of the mobile device. In this way, the current collector only needs to make linear reciprocating motion in the slide groove to adapt to the circular motion and reciprocating motion of the mobile device.

[0026] By setting a floating component, the current collector can float within a preset range relative to the connecting rod arm, thereby adapting to the error between the slide rail system and the current collector, making the slide rail system and the current collector less prone to wear.

[0027] This utility model has a simple and compact structure, low cost, and stable operation, which greatly reduces the layout length of the sliding groove and the area occupied by the factory.

[0037] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0038] Reference Figures 1 to 3 As shown, a support structure for the current collector 5 in a sliding line system includes a mounting base 1;

[0039] Linkage arm 2, which is rotatably connected to the mounting base 1;

[0040] Floating plate 3, the floating plate 3 is installed on the connecting arm 2;

[0041] The floating assembly 4 is used to mount the floating plate 3 to the connecting arm 2, and the floating plate 3 floats relative to the connecting arm 2 within a preset range via the floating assembly 4.

[0042] The current collector 5 is disposed on the floating plate 3.

[0043] In some embodiments, floating within a preset range means that, assuming the linkage arm 2 rotates relative to the mounting base 1 in the horizontal plane, the preset range is that the linkage arm 2 can move up and down within a certain range in the vertical direction. For example, when the preset range is 1 mm, the linkage arm 2 can move up and down within a 1 mm range in the vertical direction.

[0044] In some embodiments, the current collector 5 is a conventional component in the prior art.

[0045] In some embodiments, the mounting base 1 can be mounted on the mobile device in any manner. For example, the mounting base 1 can be bolted to the frame of the AGV trolley 100. Alternatively, the mounting base 1 can be directly welded to the frame of the AGV trolley 100.

[0046] In some embodiments: the mounting base 1 is provided with a rotating shaft 11;

[0047] The rotating shaft 11 is rotatably connected to the mounting base 1, and the connecting rod arm 2 is rotatably connected to the mounting base 1 via the rotating shaft 11.

[0048] Reference Figures 1 to 3 As shown, in some embodiments, the linkage arm 2 can be fixed to the pivot 11 by bolts. Alternatively, the linkage arm 2 can also be fixed to the pivot 11 by other detachable or non-detachable connection methods.

[0049] In some embodiments, a bearing 12 is provided between the rotating shaft 11 and the mounting base 1.

[0050] The bearing 12 is a deep groove ball bearing 12.

[0051] There are at least two bearings 12, and at least two bearings 12 are arranged along the length direction of the shaft 11.

[0052] Specifically, both the connecting rod arm 2 and the current collector 5 are mounted on the rotating shaft 11, which will bear a certain axial force. The deep groove ball bearing 12 can also bear a certain axial force. Understandably, the deep groove ball bearing 12 can also be replaced by other radial thrust bearings 12.

[0053] Reference Figures 1 to 3 As shown, in some embodiments: the floating component includes an elastic block 21, which is mounted on the link arm 2;

[0054] A floating shaft is fixed to the elastic block 21, and a floating plate 3 is sleeved on the floating shaft;

[0055] And the elastic element 22, one end of which abuts against the elastic block 21, and the other end of which abuts against the floating plate 3.

[0056] The elastic block 21 refers to a block-shaped structure that can undergo a certain degree of elastic deformation. Alternatively, the elastic block 21 can also be a rigid structure.

[0057] In some embodiments, the elastic element 22 is sleeved on the floating shaft. The floating plate 3 may be provided with a through hole, which mates with the floating shaft.

[0058] The elastic element 22 is a compression spring.

[0059] Specifically, taking the floating plate 3 floating vertically up and down as an example, when the floating plate 3 moves downward, the compression spring is compressed, and the floating plate 3 can float downward a certain distance. When the floating plate 3 moves upward, the compression spring releases its force, pushing the floating plate 3 upward a certain distance.

[0060] Understandably, compression springs can also be replaced with other materials that have elastic deformation capabilities.

[0061] Reference Figures 1 to 3 As shown, in some embodiments, the pivot 11 of the connecting arm 2 is perpendicular to the length direction of the connecting arm 2.

[0062] In some embodiments, the connecting arm 2 is further provided with a tension spring 23.

[0063] In some embodiments, there may be two linkage arms 2, which are arranged in parallel. One end of each linkage arm 2 is fixed to the pivot 11, and the other end of each linkage arm 2 is fixed to the elastic block 21.

[0064] In some embodiments, the linkage arm 2 can be a telescopic rod structure, meaning the length of the linkage arm 2 can be varied. When the length of the linkage arm 2 can be varied, the current collector 5 support structure in the slide rail system can adapt to more complex displacement trajectories of the AGV trolley 100.

[0065] Reference Figures 1 to 5 As shown, a specific application example is as follows: the mounting base 1 is fixed on the main body of the AGV trolley 100 device, the linkage arm 2 is fixed on the rotating shaft 11 by two screws, the tension spring 23 is fixed on the linkage arm 2 to reduce the vertical floating of the structure, the compression spring is sleeved on the shaft in the middle of the elastic block 21 to reduce the vibration of the collector 5 during operation, and two collectors 5 are fixed above the floating plate 3. The collectors 5 slide in the sliding groove 200 during the operation of the AGV trolley 100 through their own structure.

[0066] The current collector 5 has one end embedded in the sliding groove 200 and the other end connected to a power output cable. When the AGV trolley 100 moves, it drives the current collector 5 in the sliding groove system to run along the trajectory of the sliding groove 200. Since the current collector 5 can rotate 360° without jamming within the plane formed by the AGV trolley 100's running trajectory, when the AGV trolley 100 needs to move along a circular or reciprocating trajectory, the current collector 5's movement posture within the sliding groove 200 remains constant. This avoids excessive wear caused by the current collector 5's variable movement posture within the sliding groove 200, thus preventing a shortened lifespan of electrical components. Simultaneously, the arrangement trajectory of the sliding groove 200 will no longer match the running trajectory of the AGV trolley 100, reducing the length of the sliding groove 200 and allowing for more diverse movement trajectories for the AGV trolley 100.

[0067] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any person skilled in the art can easily conceive of various equivalent modifications or substitutions within the technical scope disclosed in this utility model, and these modifications or substitutions should all be covered within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
