Description

Technical Field

[0001] The utility model relates to the field of cargo truck parts, in particular to a lifting platform for cargo trucks. Background Art

[0002] In recent years, the logistics and transportation industry has made great progress and great achievements. With the rapid development of the economy and the deepening of globalization, the logistics industry has become an important cornerstone to support economic take-off. In this process, the driver team plays a vital role. They work day and night to ensure the smooth progress of logistics and transportation.

[0003] However, with the booming development of the logistics industry, internal competition is also becoming increasingly fierce. Drivers often have to take on multiple roles, ensuring that the goods are delivered to the destination on time and accurately, and ensuring the safety of the goods during transportation to prevent any possible loss or spillage. This makes the operation of covering the cargo box with tarpaulins an indispensable part of their daily work. In current logistics transportation, drivers need to climb the ladder several meters high in front of the cargo box to reach the top of the cargo box for operation. During this process, drivers need to stay alert at all times to prevent their hands and feet from slipping.

[0004] Therefore, the above-mentioned prior art has at least the following defects: currently most drivers climb with their bare hands, and once they slip, they may fall, which seriously threatens the personal safety of the drivers. Therefore, in order to ensure the safety of the drivers in the process of getting on and off the cargo box, it is necessary to take a series of measures to reduce the risk of falling accidents. Utility Model Content

[0005] The embodiment of the present application provides a lifting platform for a truck to solve the technical problem in the prior art that truck drivers need to climb manually to enter the cargo box, thereby improving the safety of the driver in the process of getting on and off the cargo box and reducing the risk of falling.

[0006] In order to solve the above technical problems, the utility model adopts the following technical solutions: a lifting platform for a truck, comprising mounting bases installed at the bottom and top of the cargo box, a slide rail and a lead screw connected between the two mounting bases, a stepper motor connected to one end of the lead screw, a slide seat fitted on the outer periphery of the lead screw, the slide rail penetrates the slide seat up and down, and a pedal assembly is connected to one side of the slide seat.

[0007] Since one end of the lead screw is connected to a stepper motor, when the driver gets on and off the cargo box, the driver steps on the pedal assembly, and the rotation of the stepper motor can drive the lead screw to rotate, thereby driving the pedal assembly to rise and fall, thereby providing convenience for the driver to get on and off the cargo box. This not only saves the driver's physical strength, but also ensures the driver's safety through the electric lifting structure.

[0008] Furthermore, a nut is embedded in the outer periphery of the lead screw, and the nut is fixed to the slide seat; when the lead screw rotates, the nut moves along the lead screw, thereby driving the slide seat connected to the nut to achieve lifting movement.

[0009] Furthermore, at least three slide rails are provided, and the upper and lower ends of the slide rails are fixed to the mounting base via connectors; this helps to disperse the force on the slide during the lifting process, thereby improving the stability and safety of the slide.

[0010] Furthermore, the slide seat includes an upper seat plate and a lower seat plate, a sleeve is provided between the upper seat plate and the lower seat plate, and the sleeve is nested in the outer circumference of the slide rail; thereby, the slide seat can move more smoothly along the slide rail during the up and down movement.

[0011] Furthermore, the slide seat also includes a vertically arranged connecting plate, one side of the connecting plate is fixedly connected to the upper seat plate and the lower seat plate, and the other side of the connecting plate is connected to the pedal assembly; the pedal assembly includes a pedal arm and a foot pedal, the upper end of the pedal arm is fixed to the connecting plate, and the lower end of the pedal arm is fixed to the foot pedal; the setting of the pedal arm makes the height of the foot pedal lower than the slide seat, so that the driver can step on the foot pedal more conveniently.

[0012] Furthermore, a reinforcement plate is provided between the pedal arm and the foot pedal.

[0013] Furthermore, a handrail is fixed on the slide; thus, the driver can hold the handrail during the process of climbing and descending.

[0014] Furthermore, a safety belt buckle is fixed on the handrail; thereby, the safety of the driver during climbing and descending can be further improved.

[0015] Furthermore, the stepper motor is fixed to a mounting base at the bottom of the cargo box and is electrically connected to a power source of the vehicle via an electrical harness.

[0016] Furthermore, a controller is provided on the wiring harness connecting the stepper motor to the power supply of the whole vehicle, and the controller cooperates with the remote control.

[0017] It can be seen from the above technical solutions that the utility model has at least the following technical effects or advantages:

[0018] Since one end of the lead screw is connected to a stepper motor, when the driver gets on and off the cargo box, the driver steps on the pedal assembly, and the rotation of the stepper motor can drive the lead screw to rotate, thereby driving the pedal assembly to rise and fall, thereby providing convenience for the driver to get on and off the cargo box. This not only saves the driver's physical strength, but also ensures the driver's safety through the electric lifting structure. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0022] In order to enable those skilled in the art to better understand the technical solutions in the present invention, the following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments in this patent, other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this patent.

[0023] The utility model discloses a lifting platform for a cargo truck. Figure 1 As shown, it includes two mounting bases 1, which are respectively fixed at the bottom and the top of the cargo box, a slide rail 2 and a lead screw 3 are connected between the two mounting bases 1, a slide seat 5 is installed on the lead screw 3, and a pedal assembly is connected to one side of the slide seat 5, thereby forming a lifting structure. When the driver gets on and off the cargo box, the driver steps on the pedal assembly, and the lead screw 3 rotates to drive the pedal assembly to rise and fall, which can provide the driver with convenience in getting on and off the cargo box, not only saving the driver's physical strength, but also ensuring the driver's safety through the electric lifting structure.

[0024] One end of the lead screw 3 is connected to a stepper motor 4, the housing of the stepper motor 4 is fixed to the mounting base 1, and when the output shaft of the stepper motor 4 rotates, the lead screw 3 can be driven to rotate. A nut is embedded in the outer periphery of the lead screw 3, and the nut is fixed to the slide 5. Therefore, when the lead screw 3 rotates, the nut moves along the lead screw 3, thereby driving the slide 5 connected to the nut to achieve lifting movement. The structure is simplified and the cost is reduced.

[0025] More specifically, the stepper motor 4 is electrically connected to the vehicle power supply 12 through a wire harness 13. The stepper motor 4 is fixed to the mounting base 1 at the bottom of the cargo box, which makes it easier to arrange the wire harness 13. In addition, a controller 14 is also installed on the wire harness 13 connecting the stepper motor 4 and the vehicle power supply 12. The controller 14 can cooperate with a remote controller, so that the stepper motor 4 can be controlled to rotate through the remote controller, thereby driving the slide 5 to rise and fall. It should be understood that the controller 14 and the remote controller are both commercially available products and are not described in detail here.

[0026] During the lifting process of the slide 5, the slide 5 cooperates with the slide rail 2. Figure 1 As shown, the slide rail 2 passes through the slide 5 up and down, thereby guiding the slide 5 during its up and down movement. In this embodiment, at least three slide rails 2 are provided, and the three slide rails 2 are provided on non-same planes. The upper and lower ends of the slide rails 2 are fixedly connected to the mounting base 1 through connectors. Not only does it provide a stable support for the slide 5, but it also ensures the stability and guidance of the slide 5 during the lifting process. At the same time, the slide rails 2 are distributed on different planes, which helps to disperse the force on the slide 5 during the lifting process, further improving the stability and safety of the slide 5.

[0027] The slide 5 includes an upper seat plate and a lower seat plate, and the upper seat plate and the lower seat plate are connected by a sleeve 6. The sleeve 6 is sleeved on the outer periphery of the slide rail 2. That is to say, the slide 5 is in contact with the slide rail 2 through the sleeve 6, so that the slide 5 can move more smoothly along the slide rail 2 during the up and down movement, which not only ensures the stability of the slide 5, but also enables the slide 5 to move smoothly during the lifting process. At the same time, the bearing capacity and service life of the slide 5 are improved.

[0028] The up and down movement of the slide 5 can drive the pedal assembly to move up and down. The slide 5 also includes a vertically arranged connecting plate 7, one side of the connecting plate 7 is fixedly connected to the upper seat plate and the lower seat plate, and the other side of the connecting plate 7 is connected to the pedal assembly. The pedal assembly includes a pedal arm 8 and a foot pedal 9, the upper end of the pedal arm 8 is fixed to the connecting plate 7, and the lower end of the pedal arm 8 is fixed to the foot pedal 9. In this embodiment, the setting of the pedal arm 8 makes the height of the foot pedal 9 lower than the slide 5, thereby providing a more convenient operating experience, allowing the driver to step on the foot pedal 9 more conveniently, reducing the difficulty of the driver's operation when loading and unloading the cargo box. In addition, in order to improve the reliability of the foot pedal 9, a reinforcing plate is also provided between the pedal arm 8 and the foot pedal 9.

[0029] In this embodiment, an armrest 10 is also fixed on the slide 5. Specifically, the armrest 10 is fixed to the upper seat plate of the slide 5. During the process of the driver climbing and descending, the driver can grasp the armrest 10, thereby improving the safety during the climbing or descending process. In addition, a safety belt buckle 11 is also fixed on the armrest 10. When the driver ascends or descends, he needs to wear a safety belt. The safety belt can be connected to the safety belt buckle 11 to ensure the safety of the driver during the climbing and descending process. It should be understood that a sensor can be installed in the safety belt buckle 11 to detect whether the safety belt is fastened. The sensor is a commercially available product, which is well known to those skilled in the art and will not be described here.
