Description

Technical Field

[0001] The utility model belongs to the technical field of forklifts, and in particular relates to a cab rotation and flipping mechanism, a cab comprising the rotation and flipping mechanism, and also relates to an electric forklift comprising a rotatable and flippable cab. Background Art

[0002] An electric forklift usually refers to an electrically driven forklift, which is easy and flexible to operate and control. Its electric steering system, acceleration control system, hydraulic control system and braking system are all controlled by electrical signals, which can greatly reduce the labor intensity of the operator. Due to its operational comfort, its scope of application and scenarios are becoming more and more extensive.

[0003] Electric forklifts, especially heavy-duty electric forklifts, are often used to transport extra-wide and extra-large cargoes. Although the cab of heavy-duty electric forklifts is set very high, when transporting extra-wide and extra-high cargoes, the front view is still inevitably blocked by the cargoes, and the forklifts are usually driven in reverse. When driving in reverse, the forklifts usually rely on the rear-view system or the driver turns his head to drive. The driving field of vision is limited, and the forklifts need to keep their eyes on the reversing screen, which poses a great safety hazard and makes the driver uncomfortable during the driving process. Utility Model Content

DETAILED DESCRIPTION

[0039] The rotating and flipping mechanism 100 and the rotatable and flippable cab 200 provided by the present invention will be further described in detail below in conjunction with the accompanying drawings of the specification.

[0040] It should be noted that when a component is referred to as being "fixed to", "disposed on", or "installed on" another component, it can be directly on the other component or indirectly on the other component. However, when an element is referred to as being "connected to" or "connected to" another element, it can be directly connected to the other element or indirectly connected to the other element. In addition, connection generally refers to the use for fixing, and the fixing here can be any conventional fixing method in the art, such as "threaded connection", "riveting", "welding", etc.

[0041] It should be understood that the terms "length", "width", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship, are based on the orientation or position relationship shown in the drawings of the specification, and are only for the convenience of describing the embodiments of the utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed or operate in a specific orientation, and therefore cannot be understood as a limitation on the utility model.

[0042] See also Figure 1 In this embodiment, a rotating and flipping mechanism 100 is provided, which includes a supporting member 110, an active rotating member 120, a rotating driving member 130, a flipping driving member 140 and a rotating limiting portion 150. The rotating and flipping mechanisms 100 respectively provide driving forces through the rotating driving member 130 and the flipping driving member 140 to complete the rotation and flipping actions.

[0043] The supporting member 110 is used to support and bear the various components in the rotating and flipping mechanism 100 , and can be specifically designed and adjusted according to the distribution and installation positions of the various components. In the present embodiment, the supporting member 110 is a bracket.

[0044] The active rotating member 120 is connected to the upper surface of the supporting member 110. Figure 1 and Figure 2As shown in FIG. 1 , in this embodiment, the active rotating member 120 is a turntable, and the active rotating member 120 can be rotated by the driving of the rotating driving member 130. Specifically, in this embodiment, the rotating driving member 130 is a motor, and its output end is connected to a driving gear 131, and the structure is as follows: Figure 3 As shown in the figure, the driving gear 131 rotates under the power of the rotating driving member 130. At the same time, a driven gear 121 is provided at the center of the lower surface of the driving rotating member 120, and the driven gear 121 and the driving gear 131 are externally meshed. The rotation of the driving gear 131 drives the driven gear 121 to rotate, thereby driving the driving rotating member 120 to rotate.

[0045] In this embodiment, the flip driving member 140 is any element capable of flipping the support member 110, such as a cylinder, and the flipping action is completed by tilting and fixing the flip driving member 140 on the lower surface of the support member 110. The flip driving member 140 and the support member 110 can be fixed in a manner known in the art, such as pin fixing, but is not limited thereto.

[0046] Furthermore, the rotation limiter 150 is provided on the upper surface of the support member 110. The specific number can be set as required. In this embodiment, four rotation limiters 150 are provided. The edge of the active rotating member 120 is placed in the rotation limiter 150 to ensure the rotation accuracy, reliability and lubricity of the active rotating member 120 during rotation. Specifically, in this embodiment, the structure of the rotation limiter 150 is as follows: Figure 4 and Figure 5 As shown in , it includes a fixing member 151, an upper slider 152, a lower slider 153 and a side guide member 154. Among them, the fixing member 151 is used to fix the upper slider 152, the lower slider 153 and the side guide member 154. Its specific structural design is not particularly limited and can be adjusted as needed. In this embodiment, the fixing member 151 is an L-shaped fixing block, the upper slider 152 and the lower slider 153 are arranged opposite to each other, the upper slider 152 is connected to it by threaded fastening, and the lower slider 153 is fixed by being embedded in the fixing member 151. The side guide member 154 in this embodiment is a side guide wheel, which is rotatably connected to the inside of the fixing member 151. Among them, the upper slider 152 and the lower slider 153 are in contact with the upper and lower surfaces of the active rotating member 120 respectively, and the side guide member 154 is in line contact with the active rotating member 120, so as to limit the active rotating member 120 from three angles of the periphery, the upper and the lower, so as to ensure the reliability and stability of its rotation process. Furthermore, a plurality of grooves are provided on the opposing surfaces of the upper slider 152 and the lower slider 153 , and grease is provided in the grooves, thereby improving the smoothness of the rotation of the active rotating member 120 .

[0047] For further information, see Figure 6-Figure 8In this embodiment, a rotatable and flippable cab is further provided, which contains the above-mentioned rotating and flipping mechanism, and also includes a cab 210, a follower rotating member 220 and a flexible arc-shaped drag chain body 230.

[0048] Among them, the cab 210 in this embodiment is an intelligent cab, and various operating switches of the rotating and flipping mechanism 100 are built in the cab 210, so as to facilitate the operation of the driver.

[0049] The follower rotating member 210 is fixedly connected to the lower surface of the cab 210. In the present embodiment, the follower rotating member 210 is also in the form of a turntable. The follower rotating member 210 and the active rotating member 120 are bolted to each other by means of holes to holes, but it is not limited to this, as long as the active rotating member 120 and the follower rotating member 210 can be fixed.

[0050] Furthermore, the flexible arc-shaped drag chain body 230 is also fixedly connected to the lower surface of the cab 210, and integrated wiring harnesses or pipelines such as electronic steering, accelerator pedal, and air-conditioning system are arranged inside it, thereby ensuring the reliability of the integrated wiring harnesses or pipelines in the rotating and telescopic state when the cab 210 rotates.

[0051] The working process of the rotating and flipping mechanism 100 and the rotatable and flippable cab 200 in this embodiment is described in detail below:

[0052] When a heavy-duty electric forklift needs to reverse to carry oversized goods, the driver controls the rotation control switch in the cab 210 according to actual needs. At this time, the rotary drive member 130 is energized, and the driving gear 131 on the rotary drive member 130 rotates at a certain speed under its drive, and the driven gear 121 and the driving gear 131 are externally meshed, and the driven gear 121 located at the center of the active rotating member 120 rotates, driving the active rotating member 120 to rotate. Since the cab 210 is connected to the active rotating member 120 through the follower rotating member 220, the cab 210 can rotate at this time. During the rotation process, the rotation limiter 150 limits the active rotating member 120 to ensure the rotation accuracy, reliability and lubrication. In addition, under the action of the flip driving member 140, the support member 110 flips along one side of the support member 110, so that the cab 210 has the functions of unilateral flipping and front and rear rotation.

[0053] In addition, it can be understood that the driver can operate the rotation control switch of the cab 210 according to actual needs, which can be self-resetting. When the desired position is reached and the switch is released, the rotating drive member 130 automatically stops. The driving gear 131 on the rotating drive member 130 has a locking function, which can lock the driven gear 121 and the cab 210 connected to the upper part through the driving rotating member 120.

[0054] In general, the rotating and flipping mechanism 100 and the rotatable and flippable cab 200 provided in this embodiment can greatly improve the safety and comfort of the electric forklift when carrying extra-large, extra-wide, and extra-high cargo.

[0055] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0056] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
