Description

Technical Field

[0001] This invention relates to the field of RV accessories technology, and in particular to an intelligent retractable electric RV pedal. Background Technology

[0002] As people's quality of life improves, RV travel, as an emerging leisure activity, is gaining popularity and is being used more and more frequently.

[0003] Traditional electric running boards for RVs mostly maintain a fixed height, unable to be flexibly adjusted to different usage scenarios. When the RV is parked on uneven ground, or when facing passengers of different heights, the fixed-height running boards can cause inconvenience for passengers getting in and out, and may even pose safety hazards. Even if some running boards have height adjustment functions, the adjustment methods are relatively complicated and mostly rely on manual operation, which is not only time-consuming and laborious, but also difficult to guarantee the accuracy and stability of the adjustment. Secondly, the extension and retraction trajectory of traditional electric running boards for RVs lacks precise control, and often deviates or jams due to changes in angle and uneven force, affecting the normal use of the running boards and may also lead to accelerated wear of components, shortening the lifespan of the running boards. In addition, although traditional electric running boards for RVs have human body sensing systems, they lack safety protection structures. If the human body sensing system misjudges or fails, the running board itself may come into accidental contact with the human body, causing injury to passengers and the vehicle, especially during rapid extension and retraction, which can cause serious injury to the human body, resulting in low safety performance. Summary of the Invention

[0004] The purpose of this invention is to provide an intelligent retractable electric step for RVs, thereby solving the technical problems existing in the prior art.

[0005] To achieve the above-mentioned objectives, the technical solution adopted by this invention is as follows:

[0006] A smart retractable electric step for a motorhome includes: a step body, a telescopic mechanism connected to the step body, and a distance sensor disposed on the working surface of the motorhome near the step body; the telescopic mechanism is disposed on both sides of the step body and hinged to the step body; the distance sensor is electrically connected to the electrical system inside the motorhome and is used to monitor the positional relationship between a human body and the step body.

[0007] Furthermore, the top of the telescopic mechanism is movably connected to the lifting mechanism, and the lifting mechanism is fixedly connected to the bottom of the RV via a mounting bracket and fixing bolts.

[0008] Furthermore, the working surface of the pedal body away from the RV is provided with an anti-collision mechanism, which is electrically connected to the distance sensor; LED light beams are provided on both working surfaces of the pedal body, which are electrically connected to the electrical system inside the RV.

[0009] Furthermore, the pedal body includes: a first step, a second step, and a third step connected in sequence; the working dimensions of the first step, the second step, and the third step are adapted to each other, and the top working surfaces are all provided with anti-slip textures; one side working surface of the first step is connected to the anti-collision mechanism.

[0010] Furthermore, the telescopic mechanism includes: a receiving frame, cylinders symmetrically arranged on the receiving frame, and a connecting arm connected to the telescopic end of the cylinder; the receiving frame is U-shaped, and its two top ends are movably connected to the lifting mechanism, and its opposite sides are sequentially provided with a first limiting rod, a second limiting rod, and a third limiting rod along its axial direction; the first limiting rod is rotatably connected to the rotating arm; the second limiting rod and the third limiting rod both pass through the third step; the cylinder output end is provided with a drive shaft, the drive shaft is connected to the rotating arm, one end of the rotating arm is hinged to the connecting arm, and the connecting arm is connected to the pedal body.

[0011] Furthermore, the connecting arm includes: a first connecting arm, a second connecting arm, a third connecting arm, and a fourth connecting arm; one end of the first connecting arm is hinged to one end of the rotating arm, and the other end is hinged to the second connecting arm; both ends of the second connecting arm are respectively hinged to the third step and the second step; both ends of the third connecting arm are respectively hinged to the third step and the first step; both ends of the fourth connecting arm are respectively hinged to the second step and the first step.

[0012] Furthermore, the lifting mechanism includes: a mounting plate and a plurality of electric cylinders disposed inside the mounting plate; the output end of the electric cylinder is connected to one end of the telescopic rod, and the other end of the telescopic rod is connected to the top of the receiving frame.

[0013] Furthermore, the anti-collision mechanism includes: a fixed base and a rubber block movably connected to the fixed base; a groove is opened on one side of the fixed base, a return spring is provided in the groove, the telescopic end of the return spring is connected to the rubber block, and a plurality of buffer strips are provided on the working surface of the rubber block away from the return spring.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] (i) Through the setting of the telescopic mechanism and the lifting mechanism, the electric cylinder drives the telescopic mechanism and the pedal body to adjust the height through the telescopic rod during use, so as to meet the height requirements of the pedal body in different scenarios. Furthermore, through the coordinated work of multiple electric cylinders, the stability of the pedal body during use can be improved. After the height of the pedal body is adjusted, the electric cylinder drives the connecting arm to rotate through the rotating arm. The setting of the first limit rod, the second limit rod and the third limit rod can accurately limit the movement trajectory of the pedal body during the telescopic process, ensuring the stability and accuracy of the pedal body telescopic process. It can better adapt to the angle changes and force conditions of the pedal during the telescopic process, ensuring that the pedal can operate reliably under various working conditions.

[0016] (ii) By incorporating a distance sensor, an anti-collision mechanism, and LED light beams, this invention can accurately monitor the positional relationship between a human body and the pedal body. When a human body is detected approaching, the pedal extension and retraction action can be automatically triggered. If the distance between the human body and the pedal body exceeds a safety threshold, the distance sensor controls the extension and retraction mechanism to stop working. Even if the pedal body comes into contact with the human body, the buffer strip, rubber block, and return spring can effectively absorb the impact force, reduce the damage caused by the collision to the pedal body and the human body, and protect the safety of passengers and vehicles.

[0025] To make the content of this invention easier to understand, the technical solutions of the embodiments of this invention will be clearly and completely described below with reference to the accompanying drawings. Identical components are represented by the same reference numerals. It should be noted that the terms "front," "rear," "left," "right," "up," and "down" used in the following description refer to directions in the accompanying drawings, while the terms "inner" and "outer" refer to directions toward or away from the geometric center of a specific component, respectively.

[0026] like Figure 1 As shown, this embodiment provides an intelligent telescopic electric step for a motorhome, including: a step body 1, a telescopic mechanism 2 connected to the step body 1, and a distance sensor located on the working surface of the motorhome 8 near the step body 1; the telescopic mechanism 2 is located on both sides of the step body 1 and is hinged to the step body 1; the telescopic mechanism 2 can maintain smooth extension and retraction without jamming or shifting, so that the entire step body 1 can remain stable when bearing the weight of passengers; the distance sensor is electrically connected to the circuit system inside the motorhome 8, and is used to monitor the positional relationship between the human body and the step body 1; the distance sensor can monitor the positional relationship between the human body and the step body 1 in real time and accurately; when the human body approaches or moves away from the step body 1, the distance sensor captures this positional change information and converts it into an electrical signal, which is transmitted to the circuit system inside the motorhome; after receiving the signal, the circuit system issues corresponding instructions to the telescopic mechanism 2 according to a preset program, thereby realizing the automatic extension and retraction control of the step body 1, bringing passengers an intelligent and convenient user experience.

[0027] like Figure 2As shown, the top of the telescopic mechanism 2 is movably connected to the lifting mechanism 3. The lifting mechanism 3 is fixedly connected to the bottom of the RV 8 via the mounting bracket 4 and fixing bolts 7. The lifting mechanism 3 provides stable support for the pedal body 1, which can withstand various loads during use and effectively prevent the pedal body 1 from loosening or shifting during use. The working surface of the pedal body 1 away from the RV 8 is equipped with an anti-collision mechanism 5. The anti-collision mechanism 5 is electrically connected to the distance sensor. The anti-collision mechanism 5 can effectively avoid collision accidents and provide reliable safety protection for passengers and the vehicle. The working surfaces on both sides of the pedal body 1 are equipped with LED light beams 6, which are electrically connected to the circuit system inside the RV 8. The LED light beams 6 allow passengers to clearly observe the location of the pedal body 1, thereby preventing safety hazards such as slipping or stepping into gaps due to poor visibility and improving passenger safety in nighttime environments.

[0028] like Figure 2-3 As shown, the pedal body 1 includes a first step 101, a second step 102, and a third step 103 connected in sequence; the working dimensions of the first step 101, the second step 102, and the third step 103 are adapted to each other, and the top working surfaces are all provided with anti-slip textures 104. The anti-slip textures 104 increase the friction between the sole of the shoe and the surface of the pedal body 1, reducing the risk of passengers slipping during getting on and off the vehicle, and enabling stable walking even in rainy or humid environments; one working surface of the first step 101 is connected to the anti-collision mechanism 5, providing safety protection for passengers during the use of the pedal body 1.

[0029] like Figure 2-5As shown, the telescopic mechanism 2 includes: a receiving frame 201, cylinders 202 symmetrically arranged on the receiving frame 201, and a connecting arm connected to the telescopic end of the cylinders 202; the receiving frame 201 is U-shaped, and its top two sides are movably connected to the lifting mechanism 3, and its opposite sides are sequentially provided with a first limiting rod 205, a second limiting rod 207, and a third limiting rod 208 along its axial direction; specifically, the first limiting rod 205, the second limiting rod 207, and the third limiting rod 208 are sequentially arranged along the transverse direction of the receiving frame 201, and their working dimensions are compatible; the first limiting rod 205 is rotatably connected to the rotating arm 204. The second limiting rod 207 and the third limiting rod 208 both penetrate the third step 103, and are used to limit and fix the third step 103. The cylinder 202 is installed on one side of the working surface of the receiving frame 201 and is electrically connected to the internal circuit system of the RV 8. Its output end is provided with a drive shaft 203, which is connected to the rotating arm 204. One end of the rotating arm 204 is hinged to the connecting arm. The drive shaft 203 efficiently transmits the driving force generated by the cylinder 202 to the rotating arm 204, which drives the telescopic mechanism 2 to move the pedal body 1. The telescopic movement involves the connecting arm connecting to the pedal body 1. Specifically, the connecting arm includes a first connecting arm 206, a second connecting arm 209, a third connecting arm 210, and a fourth connecting arm 211. The arrangement of the first connecting arm 206, the second connecting arm 209, the third connecting arm 210, and the fourth connecting arm 211 enhances the stability and flexibility of the connection between the pedal body 1 and the telescopic mechanism 2. One end of the first connecting arm 206 is hinged to one end of the rotating arm 204, and the other end is hinged to the second connecting arm 209. The first connecting arm 206 transmits the driving force of the rotating arm 204 to the second connecting arm 209. The second connecting arm 209 is hinged at both ends to the third step 103 and the second step 102, respectively, enabling the third step 103 and the second step 102 to move collaboratively under the action of driving force; the third connecting arm 210 is hinged at both ends to the third step 103 and the first step 101, respectively, strengthening the stable linkage between the third step 103 and the first step 101; the fourth connecting arm 211 is hinged at both ends to the second step 102 and the first step 101, respectively, ensuring that all parts of the telescopic mechanism 2 can cooperate closely to achieve the telescopic function;Furthermore, the first connecting arm 206, the second connecting arm 209, the third connecting arm 210, and the fourth connecting arm 211 are all made of high-strength aluminum alloy, which has a preset strength and a relatively low density, effectively reducing the weight of the entire telescopic mechanism. This allows it to withstand various loads generated during the extension and retraction of the pedal body 1 and during passenger movement. Due to its reduced weight, fuel efficiency is improved or the driving range of the electric motorhome is extended. During operation, the cylinder 202 is activated, driving the rotating arm 204 to extend via the drive shaft 203. Under the action of the first limit rod 205, the rotating arm 204 pushes the first connecting arm 206, which in turn pushes the second connecting arm 209 to push out the second step 102. At this time, the third connecting arm 210, along with the movement of the second connecting arm 209, causes the first step 101 to extend, thus achieving the extension of the pedal body 1. The cylinder 202 retracts in the opposite direction to achieve the retraction of the pedal body 1.

[0030] like Figure 6 As shown, the lifting mechanism 3 includes: a mounting plate 301 and a plurality of electric cylinders 302 disposed inside the mounting plate 301; the output end of the electric cylinder 302 is connected to one end of the telescopic rod 304, and the other end of the telescopic rod 304 is connected to the top of the support frame 201. A guide tube 303 is provided at the connection between the support frame 201 and the telescopic rod 304; the telescopic rod 304 has a preset strength and rigidity, and can stably bear various forces during the lifting process of the entire telescopic mechanism 2 and the pedal body 1; when adjusting the height of the pedal body 1, the electric cylinder 302 is activated, and the electric cylinder 302 drives the telescopic mechanism 2 and the pedal body 1 to adjust the height through the telescopic rod 304, thereby ensuring that the pedal can operate reliably under various working conditions.

[0031] like Figure 7As shown, the anti-collision mechanism 5 includes: a fixed base 501 and a rubber block 504 movably connected to the fixed base 501; a groove 502 is formed on one side of the fixed base 501, and a return spring 503 is provided in the groove 502. The telescopic end of the return spring 503 is connected to the rubber block 504. The working surface of the rubber block 504 away from the return spring 503 is provided with multiple buffer strips 505. When a collision occurs, the buffer strips 505 can disperse the collision force and increase the contact area with the colliding object through their own deformation, thereby more effectively absorbing the collision energy. This reduces the damage caused by collisions to the pedal body 1 and the human body. During operation, when the first step 101 collides with the human body, the human body first contacts the buffer strip 505. The buffer strip 505 disperses the collision force through its own deformation. Then, the buffer strip 505 drives the rubber block 504 to squeeze the return spring 503. The return spring 503 undergoes elastic deformation under the force of compression, converting the collision force into elastic potential energy, thereby effectively mitigating the collision force and reducing the damage caused to the human body and the RV 8 during the collision process. This provides a solid safety guarantee for the intelligent telescopic pedal body 1 during use.

[0032] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
