Technical Field

[0001] This utility model relates to the field of line marking vehicle technology, and in particular to a line marking vehicle chassis and line marking vehicle. Background Technology

[0002] Road marking machines, especially vibratory road marking machines, have become indispensable equipment for ground construction such as roads, highways, parking lots, plazas, and running tracks. Their core function is to efficiently and accurately mark vibratory lines that serve as warnings and guides. These lines play a crucial role in improving road safety, optimizing traffic flow, and beautifying the urban landscape. Therefore, road marking machines have made significant contributions to promoting urban planning and highway construction, shortening road construction cycles, and effectively reducing economic costs.

[0003] Currently, existing line marking vehicles mainly rely on gasoline or diesel engines as their power source. However, the relatively complex structure of these two types of engines not only increases the difficulty of equipment maintenance but also raises maintenance costs. More importantly, due to their large size, the engines occupy a significant amount of space on the line marking vehicle, affecting the overall space utilization rate. In addition, gasoline or diesel engines generate considerable noise during operation, which can disturb the working environment of construction workers and the daily lives of nearby residents. Utility Model Content

[0004] The main purpose of this utility model is to propose a marking vehicle chassis and marking vehicle, which aims to solve the problems of complex structure, low space utilization and high noise of current marking vehicles driven by gasoline or diesel engines.

[0005] To achieve the above objectives, this utility model proposes a marking vehicle chassis, including a frame and wheels disposed below the frame. The wheels include front wheels and rear wheels. The system also includes a power battery and a motor, which are mounted on the frame. The power battery supplies power to the motor, and the motor is connected to the rear wheel. A steering assembly is provided at the end of the frame away from the front wheel. The steering assembly is connected to the front wheel to control the direction of the front wheel.

[0027] This utility model proposes a marking vehicle chassis, including a frame 100 and wheels disposed below the frame 100. The wheels include a front wheel 110 and a rear wheel 120. It also includes a power battery and a motor 121. The power battery and motor 121 are mounted on the frame 100. The power battery is used to supply power to the motor 121. The motor 121 is connected to the rear wheel 120. A steering component is provided at the end of the frame 100 away from the front wheel 110. The steering component is connected to the front wheel 110 to control the orientation of the front wheel 110. A driver's seat 130 is provided on the side of the steering component away from the front wheel 110. A material bucket installation area is provided on the upper part of the frame 100 near the front wheel 110.

[0028] Reference Figures 1 to 5 The frame 100 has a front wheel 110 and a rear wheel 120 located below it. Each front wheel 110 and rear wheel 120 consists of two wheels. In other embodiments, the number of wheels in the front wheel 110 and rear wheel 120 can be adjusted according to actual needs. A power battery and a motor 121 are also mounted on the frame 100. The motor 121 is connected to the rear wheel 120, and the power battery supplies power to the motor 121, which drives the rear wheel 120 to rotate, thus enabling the marking vehicle to move. A steering assembly connected to the front wheel 110 is located at the end of the frame 100 near the rear wheel 120. The steering assembly controls the orientation of the front wheel 110, thereby controlling the direction of travel of the marking vehicle.

[0029] A driver's seat 130 is provided on the side of the steering assembly near the rear wheel 120, and a material bucket mounting area is provided on the side of the frame 100 near the front wheel 110 for mounting material buckets. Compared to the conventional design of placing the driver's seat 130 on the side of the frame 100 near the front wheel 110, placing the driver's seat 130 on the side of the frame 100 near the rear wheel 120 allows for a larger area of ​​the material bucket mounting area on the frame 100, thereby enabling the marking chassis proposed in this application to support larger material buckets. This improvement effectively reduces the number of times material needs to be added during construction, thus significantly improving work efficiency. In addition, placing the driver's seat 130 on the side of the frame 100 near the rear wheel 120 also brings another advantage: the operator can more conveniently observe the real-time status of the material buckets and the actual effect of marking from the driver's seat 130.

[0030] like Figure 2 As shown, in some embodiments, a control box 140 is provided on the frame 100, the power battery is located inside the control box 140, the driver's seat 130 is located on the top of the control box 140, and a controller for controlling the motor 121 is also provided on the frame 100.

[0031] In this embodiment, a control box 140 is also provided on the frame 100. The control box 140 is located on the side of the frame 100 facing away from the rear wheel 120, and is situated at the end of the frame 100 closest to the rear wheel 120. A power battery for supplying power to the motor 121 is installed inside the control box 140, which also houses a controller for controlling the motor 121. It should be noted that the controller can be placed at any position on the frame 100 or on other connecting parts as needed. Since the operator needs sufficient space to place their feet when sitting in the driver's seat 130, the driver's seat 130 requires a certain height. By mounting the driver's seat 130 on top of the control box 140, using the control box 140 as a support structure for the driver's seat 130, no additional structure is needed to raise the driver's seat 130. This design not only meets the operator's height requirements for the driver's seat 130 but also improves the space utilization of the marking vehicle chassis. The control box 140 not only protects the internal components such as the power battery, but also provides support for the driver's seat 130.

[0032] like Figure 3 As shown, in some embodiments, the frame 100 is also provided with an operating console 150, the operating console 150 is provided with a display screen 151 and a plurality of operating buttons 152, and the operating buttons 152 are electrically connected to the controller.

[0033] In this embodiment, an operating console 150 is also provided on the side of the driver's seat 130 facing the front wheel 110. The operating console 150 is equipped with a display screen 151 for displaying various status information of the line marking vehicle in real time. Multiple operating buttons 152 are also provided around the display screen 151. These operating buttons 152 include, but are not limited to, switches for the headlights, motor 121, and line marking machine. These operating buttons 152 are electrically connected to the controller in the control box 140. It is understood that when headlights, line marking machines, and other accessories are installed on the line marking vehicle chassis, these accessories should also be electrically connected to the controller and the power battery to ensure that the operating buttons 152 on the operating console 150 can control the corresponding accessories. In other embodiments, the operating buttons 152 can also be directly connected to the control circuit of the line marking vehicle, as long as it ensures that the operator can perform various operations on the line marking vehicle from the operating console 150 while sitting in the driver's seat 130, thereby ensuring the smooth progress of the construction task.

[0034] like Figure 3 and Figure 4As shown, in some embodiments, the steering assembly includes a steering wheel 153, a steering shaft 154, and a steering gear 155. The steering shaft 154 is disposed through the control panel 150. One end of the steering shaft 154 is connected to the steering wheel 153, and the other end is connected to the steering gear 155. The steering gear 155 is connected to the steering tie rod 111 on the front wheel 110 for transferring the movement of the steering wheel 153 to the front wheel 110.

[0035] In this embodiment, the steering assembly consists of a steering wheel 153, a steering shaft 154, and a steering gear 155. The steering shaft 154 extends through the control panel 150, with the steering wheel 153 positioned at its upper end and the steering gear 155 at its lower end. A steering tie rod 111, connected to the steering gear 155, is mounted on the front wheels 110. Since the steering shaft 154 and steering wheel 153 are fixedly connected, the steering shaft 154 rotates as the steering wheel 153 rotates. The steering shaft 154 then transmits the movement of the steering wheel 153 to the front wheels 110 via the steering gear 155 and the steering tie rod 111. This configuration allows the operator in the driver's seat 130 to control the orientation of the front wheels 110 by turning the steering wheel 153 on the control panel 150, thereby controlling the driving direction.

[0036] like Figure 2 As shown, in some embodiments, the frame 100 is also provided with an accelerator pedal 160, which is electrically connected to the controller and used to control the speed of the motor 121.

[0037] In this embodiment, the accelerator pedal 160 is located on the side of the frame 100 opposite to the front wheel 110, and between the driver's seat 130 and the control panel 150, so that the operator sitting in the driver's seat 130 can easily reach the accelerator pedal 160. The accelerator pedal 160 is electrically connected to the controller in the control box 140. Signals are transmitted to the controller via the accelerator pedal 160, and the controller adjusts the speed of the motor 121 after receiving the signals, thereby adjusting the travel speed of the road marking vehicle. Specifically, since road marking construction requires maintaining a fixed speed, the controller can also set multiple different speeds for the motor 121, which is driven by pressing the accelerator pedal 160, thus ensuring that the road marking vehicle can carry out construction at a fixed travel speed.

[0038] like Figure 2 and Figure 5 As shown, in some embodiments, the frame 100 is also provided with a brake pedal 170 electrically connected to the controller, and the front wheel 110 and / or the rear wheel 120 are also provided with a brake 122, which is connected to the brake pedal 170.

[0039] In this embodiment, the brake pedal 170 is located below the control panel 150 on the side facing the driver's seat 130. A brake caliper 122 connected to the brake pedal 170 is provided on the rear wheel 120, and the brake pedal 170 is also electrically connected to the controller. When the brake pedal 170 is depressed, the brake caliper 122 stops the rear wheel 120 from rotating and transmits a signal to the controller, which then controls the motor 121 to shut down. In other embodiments, brake calipers 122 can also be provided on both the front wheel 110 and the rear wheel 120, thereby shortening the time required for the marking vehicle to come to a complete stop from a moving state.

[0040] like Figure 2 As shown, in some embodiments, multiple ventilation holes are provided through both sides of the control box 140, and a heat exchange air path is formed between the ventilation holes on both sides of the control box 140.

[0041] In this embodiment, two sets of ventilation holes are provided, one on each side of the control box 140, forming a heat exchange airflow path between them. The flowing airflow dissipates heat from components such as the power battery inside the control box 140.

[0042] like Figure 5 As shown, in some embodiments, the rear wheel 120 is also provided with a reducer 123 and a differential connected to the motor 121.

[0043] In this embodiment, the reducer 123 and the differential are mounted on the rear wheel 120, and the reducer 123 and the differential are integrated. The reducer 123 is used to reduce the rotational speed and increase the torque, thereby improving the driving force and driving stability of the marking vehicle. When the marking vehicle turns, the inner and outer wheels travel different paths. The outer wheels need a faster rotational speed to adapt to the longer turning radius. By setting up the differential, the rotational speed of the left and right wheels can be adjusted in real time to avoid wear and vibration caused by inconsistent rotational speeds, and to prevent the marking vehicle from overturning when turning.

[0044] like Figure 2 As shown, in some embodiments, the frame 100 is provided with a plurality of fixing holes 180 for mounting the material bucket in the material bucket mounting area, and the frame 100 is also provided with a plurality of mounting holes 190 for mounting the marking machine or other construction components on both sides.

[0045] In this embodiment, a plurality of fixing holes 180 are provided in the material barrel mounting area on the frame 100, and the material barrel is securely mounted on the frame 100 by screws and these fixing holes 180. A plurality of mounting holes 190 are also provided on both sides of the frame 100, and the marking machine or other construction components can be mounted on the frame 100 by screws and these mounting holes 190.

[0046] The present invention further proposes a line marking vehicle including a line marking vehicle chassis described in the above embodiments. The specific structure of the line marking vehicle chassis refers to the above embodiments. Since the present line marking vehicle adopts all the technical solutions of all the above embodiments, it has at least all the technical effects brought about by the technical solutions of the above embodiments, which will not be described in detail here.

[0047] In summary, this application proposes a line marking vehicle chassis and a line marking vehicle. The rear wheels 120 are driven to rotate by a motor 121, and the direction of the front wheels 110 is controlled by a steering component. This allows the line marking vehicle to be driven by the motor 121. Compared to line marking vehicles using gasoline or diesel engines as power sources, the motor 121 used in this application is smaller and occupies less space in the line marking vehicle, thus providing a larger carrying capacity and helping to improve construction efficiency and equipment utilization. Furthermore, the noise generated by the motor 121 during operation is far lower than that of gasoline or diesel engines, providing a quieter working environment for construction workers and reducing noise pollution to the surrounding environment.
