Description

Technical Field

[0001] This utility model relates to the field of electric steering technology, and in particular to an electric steering device for a trolley. Background Technology

[0002] The electric steering device for trolleys is a system used to assist the steering of trolleys (such as industrial vehicles, logistics equipment, etc.). It only participates in the steering process. During the rotation of the steering control shaft, in order to reduce the physical effort required by the operator to hold the steering wheel, the motor drives the gear shaft at the output end to rotate. Because the gear shaft meshes with the power assist gear of the steering control shaft, it assists the steering control shaft to rotate and completes the steering work quickly.

[0003] Because the steering is assisted by the electric motor through the meshing contact between the power steering gear and the gear shaft, the aforementioned parts are located inside the vehicle and cannot be routinely maintained in hot weather. The high temperature causes the lubricating oil on the surface of the power steering gear and gear shaft to be consumed quickly, making it impossible to dissipate the heat generated by friction in time, which can lead to overheating, burning, or deformation of the gear. Utility Model Content

[0025] Reference Figure 1-4 An electric steering device for a trolley includes: an electric steering device body, a synchronous rotation component 6, a storage tank 7, and a conveying and resetting component 8. The electric steering device body includes a steering control shaft 1, a power assist gear 2, a motor 3, a gear shaft 4, and a mounting housing 5. The steering control shaft 1 is disposed inside the mounting housing 5, and the mounting housing 5 has a liquid inlet. The power assist gear 2 is disposed on the steering control shaft 1 and is disposed inside the mounting housing 5. The motor 3 is disposed on the outer wall of the mounting housing 5, and the gear shaft 4 is disposed on the output end of the motor 3 and is disposed inside the mounting housing 5. The power assist gear 2 meshes with the gear shaft 4. The synchronous rotation component 6 is connected to the gear shaft 4. The storage tank 7 is disposed on the outer wall of the mounting housing 5, and the bottom of the storage tank 7 has a discharge port. The conveying and resetting component 8 is disposed on the outer wall of the discharge port of the storage tank 7.

[0026] The synchronous rotation assembly 6 includes a fixed frame 601 welded to the outer wall of the mounting housing 5, a bearing inside the fixed frame 601, a connecting shaft 602 inside the bearing of the fixed frame 601, a first pulley 603 at one end of the connecting shaft 602, a second pulley 604 on the gear shaft 4, a narrow belt 605 with its two ends respectively fitted on the first pulley 603 and the second pulley 604, and an actuating rod 606 at the other end of the connecting shaft 602.

[0027] The delivery reset assembly 8 includes slide rails 801 welded to both sides of the outer wall of the outlet of the mounting housing 5. A baffle plate 802 is horizontally slidably arranged inside the slide rails 801. The top of the baffle plate 802 is made of rubber sealing material. One end of the baffle plate 802 has a round hole. A delivery hose 803 is set on the outer wall of the round hole of the baffle plate 802. The other end of the delivery hose 803 is set on the outer wall of the liquid inlet of the mounting housing 5. An arc-shaped block 804 is welded to one side of the outer wall of the baffle plate 802. The arc-shaped block 804 is in contact with the bottom toggle rod 606. A tension spring 805 is welded to the outer wall of the arc-shaped block 804. The other end of the tension spring 805 is welded to the outer wall of the storage tank 7.

[0028] In this invention, to assist the rotation of the steering control shaft 1 and thus achieve steering, the motor 3 outside the mounting housing 5 is started. The motor 3 can drive the gear shaft 4 on the output end to rotate. Since the gear shaft 4 meshes with the power assist gear 2 on the steering control shaft 1, it can assist the steering control shaft 1 to rotate and turn. During the rotation of the gear shaft 4, it can drive the synchronous rotation component 6 to rotate synchronously. Thus, the synchronous rotation component 6 provides displacement for the delivery and reset component 8. At this time, the storage tank 7 in the open state delivers the internal lubricant to the inside of the mounting housing 5, thereby lubricating the meshing part of the power assist gear 2 and the gear shaft 4.

[0029] The second pulley 604 on the gear shaft 4 is connected to the first pulley 603 via a narrow belt 605, thereby enabling the first pulley 603 to rotate. Since the first pulley 603 is connected to the connecting shaft 602 within the fixed frame 601, the connecting shaft 602 within the fixed frame 601 rotates stably. During the rotation of the connecting shaft 602 within the fixed frame 601, the actuating lever 606 on the connecting shaft 602 achieves stable rotation. When the actuating lever 606 contacts the arc-shaped block 804, the arc-shaped block 804... Displaced by the rotation of the toggle lever 606, the arc-shaped block 804 connects with the baffle plate 802, thus providing stable movement of the baffle plate 802 inside the slide rail 801. During the displacement, the delivery hose 803 connected below the baffle plate 802 moves to the outlet of the storage tank 7, thereby delivering lubricating oil to the interior of the mounting shell 5 by gravity. When the toggle lever 606 no longer contacts the arc-shaped block 804, the baffle plate 802 is pulled back to its original position by the tension spring 805, thereby sealing the outlet of the storage tank 7.
