Description

Technical Field

[0001] This invention relates to the field of logistics tractor technology, and in particular to a multi-purpose vertical electric transfer tractor for warehousing. Background Technology

[0002] Electric tractors are commonly used in factory and warehousing logistics scenarios to transfer goods and tooling trailers. These logistics transfer vehicles rely on a traction structure to connect with the load to achieve cargo turnover and are core equipment for material transportation in workshops. Existing standing tractors still have many shortcomings in actual use. On the one hand, the vehicle is only equipped with a single traction structure, making it difficult to adapt to both light tooling and heavy-duty trailers, resulting in poor equipment versatility. On the other hand, the vehicle can only be operated by the operator standing throughout the entire process, lacking a supporting structure for support and cushioning. Long-term continuous transfer operations can easily cause leg fatigue for the operator, which is not conducive to long-term continuous operation.

[0003] Therefore, those skilled in the art have provided a multi-purpose vertical electric transfer tractor for warehousing to solve the problems mentioned in the background art. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a multi-purpose vertical electric transfer tractor for warehousing.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A multi-purpose vertical electric transfer tractor for warehousing includes a frame assembly. A battery box is mounted at the rear top of the frame assembly, and a front-mounted cab is mounted at the front top. A standing and operating area is reserved between the battery box and the front-mounted cab. A driver and passenger backrest assembly is vertically fixed on the top of the battery box, and a seat is detachably mounted on the front side of the driver and passenger backrest assembly. A control handle is provided at the top of the front-mounted cab. A front-mounted traction connection mechanism is mounted at the front end of the frame assembly, and a rear-mounted traction coupling mechanism is mounted at the rear end. The rear axle drive assembly is located at the bottom rear end of the frame assembly, and drive wheels are respectively mounted on the output shafts at both ends of the rear axle drive assembly; a steering square shaft is provided at the bottom front end of the frame assembly, and follower wheels are rotatably mounted at both ends of the steering square shaft.

[0006] In the above technical solution, by setting up an independent standing operation area with a detachable seat, the operator can lean his buttocks on the seat when standing to work, which can relieve fatigue caused by standing for a long time; the frame is equipped with two sets of traction structures at the front and rear, which can be adapted to light-duty tooling and heavy-duty trailers; the rear axle drive assembly works with the drive wheels to provide walking power, and the steering square shaft works with the follower wheel to realize the steering of the whole vehicle. The walking and steering structures are arranged in sections, and the structural layout is regular.

[0007] Preferably, the front traction connection mechanism includes a traction square tube vertically fixed to the middle of the front side of the steering square shaft, a traction flange plate welded to the front end of the traction square tube, and four sets of connection and mounting holes arranged in a rectangular array on the traction flange plate.

[0008] In the above technical solution, the traction square tube is directly integrated into the front end of the steering square shaft, and the steering and traction are linked synchronously; the rectangular array four-hole structure of the traction flange plate ensures uniform stress during installation when docking with light tooling, resulting in a firm connection and convenient assembly and disassembly.

[0009] Preferably, the rear-mounted traction coupling mechanism includes a fixing plate that is bolted to the rear end of the vehicle frame assembly. Multiple sets of horizontally arranged traction plates are welded at intervals on the side of the fixing plate. A traction pin is passed through the multiple sets of traction plates. The traction pin section between two adjacent sets of traction plates constitutes the traction coupling position.

[0010] In the above technical solution, the multi-layer traction plate, together with the traction pin shaft, forms multiple sets of hook-up stations, which can be adapted to different specifications of trailer traction rings. The multi-layer plate structure improves the traction load-bearing strength, and is not easily deformed or cracked under heavy traction.

[0011] Preferably, a steering shaft is vertically mounted at the bottom of the control handle, and the steering shaft is rotatably mounted to the front cab via a bearing; the bottom of the steering shaft is connected to the middle of the top of the traction square tube, and rotating the control handle can synchronously drive the two follower wheels to achieve steering.

[0012] In the above technical solution, when the control handle is rotated, the steering shaft can drive the traction square tube, steering square shaft and the two follower wheels to deflect synchronously, thereby completing the vehicle steering operation. The bearing structure can reduce the resistance of the handle rotation.

[0013] Preferably, the driver and passenger backrest assembly includes a U-shaped support frame, with multiple transverse reinforcing ribs welded at intervals on the inner side of the U-shaped support frame, and a backrest pad is fixed to the outer side of the multiple transverse reinforcing ribs; multiple sets of waist-shaped mounting holes are opened at intervals along the vertical direction on the left and right sides of the backrest pad, and adjustment supports are mounted on both sides of the backrest pad through the waist-shaped mounting holes. The adjustable support is composed of a fixed support and a docking support connected together. Both of them have C-shaped cross sections and are arranged facing each other. Both the fixed support and the docking support are provided with assembly through holes. The fixed support is aligned with the corresponding waist-shaped assembly hole through the assembly through hole and fixed with bolts. The docking support is locked and fixed to the seat through the assembly through hole with bolts.

[0014] In the above technical solution, the U-shaped frame combined with the transverse reinforcing ribs can improve the overall structural rigidity of the backrest; the fixed support and the docking support are set with their openings facing each other, which facilitates bolt assembly operations; the fixed support can be matched with the waist-shaped mounting holes of different heights on the backrest pad to complete the installation, thereby adjusting the overall installation height of the seat to accommodate operators of different heights; the docking support is used to connect and fix the seat to the adjustment support, and the split support structure makes the seat easy to disassemble and assemble and the height adjustment operation convenient.

[0015] Preferably, mounting base plates are welded to both ends of the bottom of the U-shaped support frame, and the mounting base plates are fixed to the top surface of the battery box by bolts; a triangular reinforcing rib is added between the rear side of the U-shaped support frame and the mounting base plate.

[0016] In the above technical solution, the mounting base plate is used to realize the bolt assembly connection between the U-shaped support frame and the top of the battery box; the triangular reinforcing rib plate forms a triangular support structure between the U-shaped support frame and the mounting base plate, which improves the overall load-bearing and impact resistance of the passenger backrest component and is not easy to loosen or deform after long-term use.

[0017] Preferably, an L-shaped bracket is fixed to the rear side of the U-shaped support frame by screws, and an audible and visual warning light is installed at the top of the L-shaped bracket; a mounting base is also fixed to the top of the rear side of the U-shaped support frame, and an external antenna is mounted on the mounting base; a second external antenna is mounted at one corner of the top surface of the battery box.

[0018] In the above technical solution, the audible and visual warning lights move synchronously with the vehicle and continuously emit audible and visual reminders during transfer operations, improving the safety of passage in the factory area; the No. 1 and No. 2 dual external antennas are placed in two different locations to reduce signal obstruction and work with the wireless communication module to ensure stable transmission of remote dispatch signals.

[0019] Preferably, the battery box integrates a lead-acid power battery, a wireless communication transceiver module, and a main controller; the side wall of the battery box is provided with a charging port, and tool storage boxes are fixed to the outer walls of both the left and right sides of the box.

[0020] In the above technical solution, the battery, communication module, and controller are integrated into the battery box, with centralized wiring, good protection, and convenient maintenance; the side wall charging port facilitates vehicle charging; and the tool storage boxes on both sides can store maintenance tools and spare parts, eliminating the need to carry an additional toolbox.

[0021] Preferably, warning taillights are arranged on both the left and right sides of the rear end of the vehicle frame assembly, and LED lights are embedded in the front of the front-mounted cab.

[0022] In the above technical solution, the front LED lights can provide forward illumination in dimly lit workshops and underground warehouses; the rear warning taillights transmit vehicle position and turning signals to the rear, and the coordination of the front and rear lights comprehensively improves the safety of working at night and in low-light environments.

[0023] Compared with the prior art, the beneficial effects of the present invention are: 1. This tractor unit is equipped with both front and rear traction structures, which can be adapted to light-duty work equipment and heavy-duty trailers respectively, making it suitable for a wider range of transportation scenarios; the whole vehicle is equipped with an adjustable seat, which can be leaned against to relieve leg fatigue when the operator is standing.

[0029] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0030] Reference Figure 1-5 A multi-purpose vertical electric transfer tractor for warehousing includes a frame assembly 1, a battery box 2 mounted at the rear top of the frame assembly 1, and a front-mounted cab 3 mounted at the front top. A standing operating area is reserved between the battery box 2 and the front-mounted cab 3. A driver's backrest assembly 4 is vertically fixed to the top of the battery box 2, and a seat 5 is detachably mounted on the front side of the driver's backrest assembly 4. The operator can stand and operate the vehicle throughout the entire operation, and can lean against the seat during operation to reduce standing fatigue. A control handle 6 is installed at the top of the front-mounted cab 3. The control handle 6 integrates multiple sets of button switches, which are electrically connected to the main controller 21. The button switches can control the vehicle's forward and reverse movement, start and stop, LED lighting 24, audible and visual warning lights 15, and warning taillights 23, respectively. An emergency stop button is also provided to cut off the vehicle's power output with one click in case of an emergency. A front-mounted traction connection mechanism 7 is set at the front of the frame assembly 1, and a rear-mounted traction hook-up mechanism 8 is set at the rear. The rear axle drive assembly 9 is mounted at the bottom rear end of the frame assembly 1. Drive wheels 10 are mounted on the output shafts at both ends of the rear axle drive assembly 9, and the vehicle moves by means of the drive wheels. A steering square shaft 11 is horizontally mounted at the bottom front end of the frame assembly 1. Follower wheels 12 are rotatably mounted at both ends of the steering square shaft 11. The follower wheels cooperate with the steering square shaft to complete the vehicle steering action.

[0031] The front traction connection mechanism 7 includes a traction square tube 71, which is vertically fixed to the middle of the front side of the steering square shaft 11. A traction flange plate 72 is welded to the front end of the traction square tube 71. The traction flange plate 72 has four sets of rectangular arrayed connection and installation holes. The light traction tool can be locked and fixed to the flange plate with bolts. The traction square tube swings synchronously with the steering square shaft to ensure that the tool and the vehicle turn synchronously.

[0032] The rear-mounted towing and hooking mechanism includes a fixed plate 81, multiple sets of towing plates 82, and a towing pin shaft 83. The fixed plate 81 is fixed to the rear end of the frame assembly 1 by bolts. Multiple towing plates 82 are horizontally and spaced on the side of the fixed plate. The towing pin shaft 83 passes through all the towing plates. The pin shaft segments between adjacent towing plates form towing hooking positions, which can hook towing rings of different specifications of trailers. The multiple layers of towing plates disperse the traction force and improve the overall traction load capacity.

[0033] The bottom of the control handle 6 is vertically mounted with a steering shaft 13. The steering shaft 13 is rotatably mounted to the front-mounted cab 3 via a bearing. The bottom of the steering shaft 13 is connected to the middle of the top of the traction square tube 71 via a transmission. When the operator rotates the control handle, the steering shaft rotates synchronously and drives the traction square tube and the steering shaft to swing, thereby driving the follower wheels on both sides to deflect synchronously and achieve vehicle steering. The bearing can reduce the friction of the handle rotation, making operation easier. When the operator holds the control handle, their fingers can directly press the button switch on the handle without having to lift their hand to switch operations, making operation convenient.

[0034] The main body of the driver and passenger backrest assembly 4 is a U-shaped support frame 41. Multiple transverse reinforcing ribs 42 are welded at intervals on the inner side of the U-shaped support frame 41. The outer side of the transverse reinforcing ribs together fix the backrest pad 43. The transverse reinforcing ribs can improve the overall rigidity of the frame and the pad. Multiple sets of waist-shaped mounting holes 44 are opened on the left and right sides of the backrest pad 43 along the vertical direction. The adjustment support is assembled on both sides of the backrest pad through the waist-shaped mounting holes. The adjustment support consists of a C-shaped fixed support 45 with openings facing each other and a docking support 46. Both have mounting through holes. During assembly, the fixed support is locked by bolts through the mounting through holes and waist-shaped mounting holes. The mounting position of the support can be adjusted by selecting different height waist-shaped holes, thereby changing the seat height. The docking support is locked to the seat 5 through bolts through the mounting through holes, realizing the detachable assembly of the seat.

[0035] The bottom ends of the U-shaped support frame 41 are welded with mounting plates 47. The mounting plates 47 are laid flat on the top surface of the battery box 2 and locked with bolts to complete the assembly connection between the U-shaped support frame and the top of the battery box. The rear rod of the U-shaped support frame 41 is welded with triangular reinforcing ribs 48 between the mounting plates 47 and the mounting plate. The triangular structure forms a stable support, improving the overall load-bearing capacity and deformation resistance of the backrest.

[0036] The rear side of the U-shaped support frame 41 is fixed with screws to the L-shaped bracket 14. The top of the L-shaped bracket 14 is equipped with an audible and visual warning light 15, which continuously emits audible and visual warnings during vehicle operation. The top of the rear side of the U-shaped support frame 41 is equipped with a mounting base 16, on which a first external antenna 17 is mounted. A second external antenna 18 is mounted on the top corner of the battery box 2. The two antennas are placed in two separate locations to reduce the impact of vehicle body obstruction on the wireless signal and ensure the stability of the wireless communication transceiver module signal.

[0037] The battery box 2 integrates a lead-acid power battery 19, a wireless communication transceiver module 20, and a main control controller 21. The battery supplies power to all electrical components of the vehicle, and the main control controller centrally manages the driving, lighting, communication, and warning functions. It also receives operation signals from the various button switches on the control handle 6 and executes corresponding actions. A charging port is opened on the side wall of the battery box, which can be directly connected to an external charger for charging. Tool storage boxes 22 are fixed to the left and right outer walls of the box for storing maintenance tools and spare parts.

[0038] Warning taillights 23 are symmetrically arranged on the left and right sides of the rear end of the chassis assembly 1. They are illuminated simultaneously when the vehicle turns or reverses, transmitting the vehicle's position signal to the rear. LED lights 24 are embedded in the front of the front-mounted cab 3, providing forward illumination in dim environments and improving safety in low-light working conditions.

[0039] Working principle: This tractor unit adopts a standing operation mode. The operator stands in the operating area between the battery box and the front cab, and holds the control handle to control the vehicle's steering. The rear axle drive assembly drives the drive wheels to move forward and backward. The operator can control the vehicle's start and stop, lights, and warning lights by pressing the button switches integrated on the control handle. The emergency stop button can quickly cut off the power. During operation, the operator can lean back on the seat to relieve fatigue from standing for long periods of time. Depending on the type of cargo being towed, a front-mounted towing coupling mechanism can be selected to connect to light-duty workpieces, or a rear-mounted towing coupling mechanism can be used to connect to heavy-duty trailers.

[0040] During transport operations, the audible and visual warning lights remain on, and the No. 1 and No. 2 external antennas, in conjunction with the wireless communication transceiver module, receive remote dispatch commands. The front LED lights and rear warning taillights are activated simultaneously to ensure safe passage through the factory area. If the seat height needs to be adjusted, loosen the fixing bracket bolts, slide the bracket up and down along the waist-shaped mounting holes on the backrest pad to the appropriate height, and then tighten the bolts. The tool storage boxes on both sides can store matching maintenance parts. The modular assembly of all components of the vehicle makes disassembly, assembly, and maintenance convenient.

[0041] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
