Description

Technical Field

[0001] This utility model relates to the technical field of handrail installation structures, and specifically to a handrail installation structure for a standing electric transport vehicle. Background Technology

[0002] Electric pallet trucks are transport vehicles powered by electricity. Due to their excellent short-distance transport performance, they are widely used in factories, warehouses, logistics, freight stations and other occasions. Electric pallet trucks can be divided into standing pallet trucks and seated pallet trucks according to their usage scenarios. Standing pallet trucks are usually used in occasions where the driver's field of vision is required. However, in order to ensure the stability of the driver's standing position, handrails are usually installed in the cab to maintain the stability of the driver's body.

[0003] In existing technology, handrails are usually installed on the face shield of the operating table to facilitate the driver's operation of the transport vehicle while holding the handrail. However, in order to install the handrail, the face shield usually needs to be divided into two parts, and then the handrail is clamped and fixed by the two parts of the face shield. This will result in poor overall aesthetics of the face shield and easy occurrence of problems such as curling edges. Utility Model Content

[0004] This utility model addresses the aforementioned problems. Its purpose is to provide a handrail mounting structure for a standing electric transport vehicle. By arranging a mounting base inside the mask, the handrail does not need to be positioned by the mask itself. The one-piece molding of the mask can improve its aesthetics and is easy to mold.

[0031] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0032] like Figure 1-4 As shown, a handrail mounting structure for a standing electric pallet truck includes a mounting base 300 and a handrail body 400.

[0033] In this embodiment, the transport vehicle includes a frame 100 and a cab 200 located on the frame 100. The cab 200 has a standing area and an operating platform 210 located on one side of the standing area. The operating platform 210 includes a mask 211 and multiple control units 212 located on the mask 211. The multiple control units 212 are used to control other parts of the transport vehicle to perform corresponding actions. The driver needs to stand in the standing area to operate the multiple control units 212 located on the mask 211 to control the vehicle to perform corresponding actions. However, since the driver is standing, the driver is prone to instability due to vehicle swaying during the operation of the transport vehicle. The driver's body swaying may cause him to tip over or even accidentally touch the control unit 212, which is unsafe. Therefore, a handrail needs to be installed on the operating platform 210 for the driver to hold on to help stabilize his body.

[0034] Specifically, the mounting base 300 is located inside the face shield 211, and the mounting base 300 includes a mounting plate 310 and a movable pressure plate 320. The mounting plate 310 is fixedly connected to the inner wall of the face shield 211, and the movable pressure plate 320 is detachably connected to the mounting plate 310 and can be closed with the mounting plate 310 to form a variable-diameter mounting groove. That is, the movable pressure plate 320 can move towards or away from the mounting plate 310 to adjust the diameter of its mounting groove. The armrest body 400 includes a grip section 410 and a mounting section 420. The grip section 410 is located on the outside of the face shield 211, and the mounting section 420 can be inserted into the mounting groove. Before the mounting section 420 is inserted into the mounting groove, the movable pressure plate 320 can move towards... The movable plate 320 moves away from the mounting plate 310 to enlarge the size of the mounting groove, making it easier for the mounting section 420 to be inserted into the mounting groove. After the mounting section 420 is inserted into the mounting groove, the movable pressure plate 320 can move towards the side closer to the mounting plate 310 to clamp and fix the mounting section 420, thereby achieving the installation and positioning of the handrail body 400. This method can be used for handrail bodies 400 of different diameters. At the same time, since the faceplate 211 is not needed for positioning, in this embodiment, the faceplate 211 is made by one-piece molding, which can effectively avoid the edge warping phenomenon caused by splicing multiple pieces, improve the overall aesthetic performance of the faceplate 211, and at the same time reduce the molding difficulty of the faceplate 211, avoiding the need for multiple cover pieces to be molded separately.

[0035] In this embodiment, the multiple control units 212 include, but are not limited to, a steering wheel or joystick for controlling the overall steering and driving of the transport vehicle, a lift / lower control handle / button for controlling the lifting of the forks, a tilt control handle / button for controlling the forward and backward tilting of the mast, and a function selection switch / button for selecting gear / speed / working mode.

[0036] Furthermore, a through hole is provided on the face mask 211 to expose the mounting groove, so that the mounting section 420 can be inserted into the mounting groove through the through hole. Of course, a transition fit should be adopted between the through hole and the handrail body 400 to prevent dust or other impurities from entering the face mask 211 through the gap between the through hole and the handrail body 400. At the same time, the transition fit between the through hole and the handrail body 400 can provide a positioning for the handrail body 400 and prevent the mounting base 300 from being subjected to excessive force.

[0037] Furthermore, the movable pressure plate 320 is detachably connected to the mounting plate 310 via multiple bolts 330, and the distance between the movable pressure plate 320 and the mounting plate 310 can be adjusted via the bolts 330 to adjust the size of the mounting groove. The bolts 330 include a screw and a nut. The screw passes through the movable pressure plate 320 and engages with the threaded hole on the mounting plate 310. The screw can be displaced by rotating the nut, thereby causing the movable pressure plate 320 to move closer to or further away from the mounting plate 310, thereby clamping and releasing the mounting section 420 located in the mounting groove. When the handrail body 400 needs maintenance, the mounting section 420 can be released via the bolts 330.

[0038] Furthermore, to facilitate the operation of the bolts 330, an opening 211a is provided on one side of the face shield 211. This opening 211a is used to expose multiple bolts 330, with the nuts of the multiple bolts 330 facing the opening 211a. The nuts are provided with internal hexagonal holes, and the operator can use a hex wrench to insert into the internal hexagonal holes of the nuts to adjust the multiple bolts 330. Of course, the existence of the opening 211a also provides convenience for the installation and disassembly of the handrail body 400, avoiding the need to disassemble the entire face shield 211, and facilitating installation and maintenance.

[0039] Furthermore, a baffle 211b is provided inside the opening 211a. The baffle 211b is detachably connected to the mask 211. The baffle 211b is there to cover the opening 211a, improve the overall aesthetics, and prevent dust and other impurities from entering the mask 211.

[0040] In this embodiment, multiple control units 212 need to be connected to wires and electrical components, which are all arranged inside the face shield 211. Therefore, the face shield 211 needs to provide good protection to prevent the wires and electrical components from being corroded.

[0041] In this embodiment, the mounting plate 310 is a flat plate, but the movable pressure plate 320 is an arc-shaped plate with an arc-shaped groove. The arc-shaped groove and the mounting plate 310 cooperate to form a mounting groove, which conforms to the shape and structure of the mounting section 420 and can better clamp and position the mounting section 420.

[0042] Specifically, a first locking plane 421 is provided on one side of the mounting section 420, and a second locking plane is provided on the first side of the mounting groove. The second locking plane can fit against the first locking plane 421, thereby preventing the mounting section 420 from rotating in the mounting groove. In this embodiment, taking the mounting section 420 as an example as a shaft segment, when the mounting plate and the mounting plate 310 are used for fixing, the mounting section 420 is relatively easy to rotate, which can lead to unstable positioning of the handrail body 400. This can easily cause a safety accident, especially after the driver applies force to the handrail body 400. After the first locking plane 421 and the second locking plane are set to abut against each other, it is completely locked and cannot rotate.

[0043] The second locking plane is set on the mounting plate 310. When the mounting section 420 is inserted into the mounting groove, the second locking plane fits with the first locking plane 421. During the processing of the mounting section 420, the first locking plane 421 can be milled, but the second locking plane is the bottom side of the mounting plate 310 and no further processing is required.

[0044] Furthermore, in order to improve the driver's grip comfort, a rubber sleeve 411 is provided on the outer side of the grip section 410. The surface of the rubber sleeve 411 is provided with micron-level stripes, dot matrix or Braun texture, which can increase the coefficient of friction and prevent slippage caused by dirty hands or oil. Of course, the grip section 410 and the rubber sleeve 411 can be molded simultaneously by two-color injection molding, which can effectively ensure the bonding force between the two.

[0045] In this embodiment, the grip section 410 has an ergonomic arc shape in cross section, which can effectively improve grip comfort.

[0046] Furthermore, a knob controller 412 is provided on the end of the grip section 410 away from the face mask 211, and a cable channel is provided inside the armrest body 400 for laying the wires connecting the knob control. The knob controller 412 is located in the grip section 410 to improve its ease of operation, facilitate thumb operation, and is more ergonomic.

[0047] In this embodiment, a handrail mounting structure for a standing electric pallet truck is disclosed, including a mounting base 300 and a handrail body 400. The mounting base 300 is located inside the face shield 211 of the driver's cab 200, and includes a mounting plate 310 and a movable pressure plate 320. The mounting plate 310 is fixedly connected to the inner wall of the face shield 211, and the movable pressure plate 320 is detachably connected to the mounting plate 310 and can be closed with the mounting plate 310 to form a variable-diameter mounting groove. The handrail body 400 includes a grip section 410 and a mounting section 420, and the grip section 410 is located inside the face shield. On the outside of 211, the mounting section 420 can be inserted into the mounting groove. After the mounting section 420 is inserted into the mounting groove, the movable pressure plate 320 can move towards the side closer to the mounting plate 310 to clamp and fix the mounting section 420, thereby achieving the installation and positioning of the handrail body 400. It can be used for handrail bodies 400 of different diameters. At the same time, since it is not necessary to use the faceplate 211 for positioning, the faceplate 211 is made by one-piece molding, which can effectively avoid the edge warping caused by splicing multiple pieces, improve the overall aesthetic performance of the faceplate 211, and at the same time reduce the molding difficulty of the faceplate 211.
