Description

Technical Field

[0001] This utility model relates to the technical field of three-way stacker trucks, and specifically to a chassis assembly and a three-way stacker truck. Background Technology

[0002] Three-way stacker trucks, as core equipment in the warehousing and logistics field, are widely used in high-density warehousing scenarios such as manufacturing, e-commerce logistics, and pharmaceutical cold chain due to their forks' flexible three-way loading and unloading capabilities. This allows them to operate efficiently in ultra-narrow aisles of up to 1.6 meters, significantly improving warehouse space utilization. However, with the increasing demand for automation and intelligence, and the widespread adoption of high-level operations (lifting height up to 16 meters), the existing three-way stacker truck frame structure is gradually revealing the following key issues:

[0003] 1. Poor spatial layout: The hydraulic system, battery pack, and electrical components of traditional three-way stacker trucks are often scattered or stacked in the same compartment. In particular, it is common to place electrical components and hydraulic systems in the same compartment, which will cause wires and hydraulic pipes to become tangled, affecting assembly and disassembly efficiency. At the same time, due to the chaotic layout, the weight of the left and right sides of the stacker truck is not consistent. When working at high positions, the center of gravity shifts, which can easily cause the stacker truck to tip over.

[0004] 2. Difficult to maintain: Due to the chaotic layout, the existing hydraulic system and electrical components may require the disassembly of multiple parts during maintenance, making it impossible to directly maintain the parts that need repair. Utility Model Content

[0005] This utility model was developed in consideration of the aforementioned problems. The purpose of this utility model is to provide a frame assembly and a three-way stacker vehicle with a reasonable layout, which can improve the assembly and maintenance efficiency of each component.

[0006] To achieve the above objectives, this utility model provides a vehicle frame assembly, comprising:

[0034] 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.

[0035] like Figure 1-3As shown, a vehicle frame assembly includes a chassis 110, a housing 120, a control panel 130, a drive wheel assembly 140, and a roof guard 150. The drive wheel assembly 140 provides movable support for the chassis 110, which in turn provides support for other components. The housing 120 is used to house other components and the driver. The control panel 130 is located on the housing 120, and the driver can control the overall movement of the vehicle through the control panel 130. The roof guard 150 is located directly above the housing 120 and provides shielding and protection for the driver and the control panel 130.

[0036] The cabin 120 is located at the rear end of the chassis 110. The cabin 120 includes a front cabin and a rear cabin arranged in a longitudinal direction. The front cabin includes a hydraulic compartment 121 and a battery compartment 122 arranged vertically, with the hydraulic compartment 121 located directly above the battery compartment 122. The rear cabin includes an electrical compartment 123 and a driver's cabin 124 arranged horizontally. The hydraulic compartment 121 houses hydraulic components, the battery compartment 122 houses battery components, the electrical compartment 123 houses electrical components, and the driver's cabin 124 provides a standing area for the driver to operate the equipment. This functional area division allows for the separate arrangement of various functional components, avoiding the need for separate hydraulic compartments. Because leakage can contaminate other components, it also avoids the tangling of wires and oil pipes. During installation, it only needs to be installed in the corresponding area, which can improve assembly efficiency. Moreover, through reasonable left and right arrangement, the center of gravity of the vehicle can be centered, reducing the risk of vehicle rollover. The control panel 130 is detachably fixed to the top of the compartment 120. It can be used to seal the electrical compartment 123 and the hydraulic compartment 121. The driver can stand in the driver's cab 124 and operate the control panel 130. When the control panel 130 is removed, the electrical compartment 123 and the hydraulic compartment 121 can be opened, thereby realizing the assembly and maintenance of electrical components and hydraulic components.

[0037] In this embodiment, the control panel 130 is equipped with multiple control units, including a display screen, a steering handle, an emergency stop switch, a gear position switch, a lifting switch, a side shift switch, and a rotary switch. The display screen is used to display the vehicle's driving speed and usage status. The steering handle is used to control the vehicle's steering. The emergency stop switch is used to control the vehicle's emergency braking. In case of an accident, the emergency stop switch can be pressed to brake. The gear position switch is used to control the vehicle's driving speed. The lifting switch, side shift switch, and rotary switch are used to control the forks to move in three directions.

[0038] Furthermore, to facilitate the installation and replacement of battery components, a first opening is provided on the compartment 120 on one side of the battery compartment 122. A first door 122a is provided in the first opening, and one side of the first door 122a is hinged to the compartment 120. The first opening can be opened or closed by rotating the first door 122a. Under normal conditions, the first door 122a is in the closed state. However, when installing or replacing battery components, the first door 122a can be rotated to open the first opening to directly expose the battery compartment 122, making it easier to install the battery components into the battery compartment 122 or remove the battery components from the battery compartment 122 for loading and unloading. Since the first door 122a is connected by a hinge, opening the first opening is simpler and more convenient.

[0039] Furthermore, to improve the cabin 120, a second opening is provided, and a second door 123a is provided in the second opening. One side of the second door 123a is hinged to the cabin 120. The second door 123a can open the second opening to expose the electrical compartment 123. Similarly, the position of the second door 123a can be switched by rotating it, thereby opening or closing the second opening. When the second opening is open, electrical components can be installed into the electrical compartment 123, and the electrical components located in the electrical compartment 123 can also be maintained.

[0040] Furthermore, the second opening is located at the corner of the electrical compartment 123, and the second door 123a is arc-shaped to match the overall shape of the compartment 120 and improve the overall aesthetics.

[0041] The drive wheel assembly 140 includes a drive wheel 141, a caster wheel 142, and a driven wheel 143. The drive wheel 141 and the caster wheel 142 are symmetrically arranged on both sides of the bottom rear end of the chassis 110, and the multiple driven wheels 143 are symmetrically arranged in pairs on both sides of the bottom front end of the chassis 110. That is, the drive wheel 141 is sideways, so that the corresponding electrical components can also be offset, thereby achieving a reasonable layout of each component.

[0042] Furthermore, the drive wheel 141 is located on the left side of the rear bottom of the chassis 110, and the electrical compartment 123 is located directly above the drive wheel 141, which facilitates the electrical components to control the drive wheel 141 to move.

[0043] The protective roof 150 is fixed directly above the cabin 120, providing protection for the control panel 130 and the driver's cabin 124, preventing cargo from falling and directly impacting them. The protective roof 150 includes support rods 151 and a top frame 152 fixed to the two support rods 151. Lights 153 are provided on both sides of the top frame 152 for vehicle illumination and providing a high-level field of vision. However, the lights 153 require electricity. Therefore, in this embodiment, the support rods 151 are hollow to allow wires to pass through and connect to the lights 153. The support rods 151 can shield the wires, improving the overall aesthetics and providing protection. In addition to the lights 153 and other electrical appliances, cameras and other electrical appliances are also installed on the protective roof 150, which are also powered by wires in the support rods 151.

[0044] Furthermore, a backrest 124a is provided in the cockpit 124. The backrest 124a is located on the upper part of the side of the cockpit 124 away from the control panel 130. The backrest 124a provides support for the driver's back, making it more comfortable and stable to stand.
