Technical Field
[0001] This utility model relates to the field of production and application of handrail boxes for engineering vehicles, specifically to an electric lifting and sliding handrail box. Background Technology
[0002] Most existing engineering vehicle handrail boxes are fixed. When operating, the operator places both hands on the control handle. Due to the fixed mechanical structure, only a fixed operating posture can be used. They lack electric adjustment function and cannot be adjusted to a corresponding comfortable area according to the operator's physique and posture. This leads to increased operator fatigue and increased driving risks during long-term driving operations.
[0003] How to make the armrest box meet the driving needs of different drivers is a technical problem that urgently needs to be solved at this stage.
[0004] The information disclosed in this background section is intended only to enhance the understanding of the general background of this utility model and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art. Utility Model Content
[0005] To address the aforementioned technical problems, this utility model proposes an electrically adjustable and sliding armrest box to meet the driving needs of different drivers, improve driving comfort, and reduce driving risks.

The two ends of the lead screw are fixedly connected to the armrest box body disposed inside the armrest box. Under the action of the linear lead screw stepper motor, the lead screw drives the armrest box body to move back and forth along the linear slide rail.
[0014] It is also worth noting that the electric up-and-down transmission unit includes a pair of guide column fixing brackets disposed at the bottom of the transition plate, guide columns disposed within the guide column fixing brackets, and linear bearings disposed on the base housing that cooperate with the guide columns; the two guide columns are disposed on both sides of the lifting motor.

[0031] 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.
[0032] This utility model provides an electric lifting and sliding armrest box. Its working principle is to use electric drive technology to realize the electric transmission component to move the armrest box body up and down in the vertical direction and forward and backward in the horizontal direction, so as to meet the driving needs of different drivers, improve driving comfort and reduce driving risks.
[0033] The present invention will be further described in detail below with reference to embodiments and specific implementation methods.
[0034] like Figures 1-3 As shown, an electric lifting and sliding handrail box includes a base box 1, a transition connection assembly 2 disposed on the base box, a handrail box 3 disposed on the transition connection assembly, and an electric transmission assembly 4 for electrically driving the handrail box.
[0035] The transition connection assembly includes a transition bracket 21 and a transition plate 22 horizontally disposed on the transition bracket, and the armrest box is disposed on the transition plate.
[0036] The electric drive assembly is capable of driving the armrest box to move up and down and back and forth relative to the base box. Specifically, the electric drive assembly includes an electric up-and-down drive unit and an electric back-and-forth drive unit;
[0037] The electric up-and-down transmission unit includes a lifting motor 411 installed in the base box, a pair of guide column fixing brackets 412 installed at the bottom of the transition plate, guide columns 413 installed in the guide column fixing brackets, and linear bearings 414 installed on the base box and cooperating with the guide columns; the top of the lifting motor is connected to the bottom center of the transition plate; the two guide columns are installed on both sides of the lifting motor.
[0038] The electric front and rear transmission unit includes a linear lead screw stepper motor 421 disposed in the armrest box, a lead screw 422 cooperating with the linear lead screw stepper motor, and a linear slide rail 423 disposed on the transition plate. The two ends of the lead screw are fixedly connected to the armrest box body 31 disposed inside the armrest box. Under the action of the linear lead screw stepper motor, the lead screw drives the armrest box body to move back and forth along the linear slide rail.
[0039] The electric front and rear transmission unit also includes a limiting component disposed in the armrest box. The limiting component includes a front limiting block 43 that moves with the lead screw, a rear limiting block 44 that moves with the lead screw, a front limiting switch 45 that cooperates with the front limiting block, and a rear limiting switch 46 that cooperates with the rear limiting block. The front limiting switch and the rear limiting switch are mounted on a limiting mounting plate, which is mounted in the armrest box.
[0040] A four-way adjustment switch 5 is also provided on the side wall of the armrest box, and a control module 6 is provided in the base box. The four-way adjustment switch is connected to the control module. The control module is connected to the lifting motor and the linear screw stepper motor.
[0041] The specific steps for using this utility model are as follows: For example Figures 1-3 When in use, the operator can adjust the armrest box to a comfortable range according to their height and arm length and their own driving habits. By pressing the front and rear buttons of the four-way adjustment switch 5, the operator can send corresponding control commands to the control module 6. [The control module controls the operation of the linear screw stepper motor and the lifting motor, which is a relatively mature technology at present, and will not be elaborated here.]
[0042] When the forward and backward position needs to be adjusted, the control module controls the linear lead screw stepper motor to work. Under the action of the linear lead screw stepper motor, the lead screw 422 moves back and forth. Since the lead screw is fixedly connected to the armrest box 31 inside the armrest box, it can push the armrest box to move back and forth synchronously. At the same time, the presence of the linear slide rail 423 can ensure the stability of the forward and backward movement and avoid deviation. Furthermore, during the forward movement, when the front limit switch 45 contacts the front limit block 43, the front limit switch 45 sends an electrical signal to the control module 6, thereby controlling the linear lead screw stepper motor to stop. During the backward movement, when the rear limit switch 46 contacts the rear limit block, it sends an electrical signal to the control module 6, thereby controlling the linear lead screw stepper motor 421 to stop.
[0043] When height adjustment is required, pressing the up and down buttons of the four-way adjustment switch 5 sends an electrical signal to the control module 6, controlling the lifting motor 411 to move up and down. This movement is achieved via a transition plate, causing the entire handrail box to move up and down. Simultaneously, the guide column 413, guide column fixing bracket 412, and linear bearing 414 ensure stable vertical movement. Furthermore, the lifting motor 411 contains a limit switch, which immediately stops movement when the limit position is reached.
[0044] This device is suitable for operators of different body types. Users can adjust the armrest box to a comfortable position based on their height and arm length, increasing comfort. The optimized structure of the device provides sufficient walking space for drivers getting in and out of engineering vehicles. The device is electrically controlled, requiring no significant changes in movement; operators can simply move their fingers to operate buttons to slide the armrest box forward and backward and raise and lower it, greatly reducing operator fatigue.
[0045] The above description is only a preferred embodiment of an electric lifting and sliding armrest box disclosed in this utility model. It should be noted that for those skilled in the art, several modifications and improvements can be made without departing from the inventive concept of this utility model, and these all fall within the protection scope of this utility model.
