Description

Technical Field

[0001] This utility model relates to the field of vehicle door pedal technology, specifically a transportation vehicle door pedal structure. Background Technology

[0002] Transport vehicles are mainly used for transporting general goods, including trucks and vans. The door steps of transport vehicles are important components for getting people on and off the vehicle or loading and unloading goods. Their design must take into account safety, durability and practicality. The door steps are fixed to the vehicle body at the bottom of the car door to facilitate the driver and passengers to get on the vehicle.

[0003] The large size of existing truck cabs results in a significant distance between the bottom of the cab and the ground. To allow passengers to easily step onto the door step to enter the cab, the step is often positioned closer to the ground. This design further increases the distance between the step and the bottom of the cab. Shorter individuals, even after stepping onto the step, still have some distance between themselves and the cab space, requiring them to use the seat or door handle to assist them in entering the vehicle, which is quite strenuous. Utility Model Content

[0004] The purpose of this utility model is to provide a transportation vehicle door step structure to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A transportation vehicle door sill structure, comprising:

[0007] A base pedal, with an auxiliary pedal movably mounted above it;

[0008] A support assembly is movably disposed between the base pedal and the auxiliary pedal. The support assembly includes two No. 1 support plates movably disposed between the base pedal and the auxiliary pedal, and a No. 2 support plate is hinged to one end of each of the two No. 1 support plates.

[0009] Two limiting components are fixedly installed on one side of the base pedal and the auxiliary pedal, respectively. Each limiting component includes a push plate, and pawls are symmetrically fixedly installed on one side surface of the push plate.

[0010] Furthermore, a first connecting seat is symmetrically fixedly installed on the inner side of the auxiliary pedal, and a second connecting seat is symmetrically fixedly installed on the inner surface of the base pedal. Both the first and second connecting seats are rotatably connected to a rotating shaft.

[0011] Preferably, the rotating shaft inside the first connecting seat is fixedly connected to the first support plate at the corresponding position, and the rotating shaft inside the second connecting seat is fixedly connected to the second support plate at the corresponding position.

[0012] Preferably, one end of each of the two second support plates is fixedly connected to a first connecting shaft, and the two rotating shafts on the same side are both fixedly connected to a second connecting shaft. Ratchets are symmetrically fixedly installed on the outer surface of the second connecting shaft, and the pawl and the ratchet are movably engaged.

[0013] Furthermore, protective frames are symmetrically fixedly installed on both sides of the base pedal, multiple connecting ears are fixedly installed on the inner side of the base pedal, and through holes are opened on both sides of the base pedal and the auxiliary pedal.

[0014] Preferably, the base pedal and the auxiliary pedal are symmetrically fixedly installed with reinforcing plates on both sides of their interior surfaces. The push plate slides and fits in contact with the reinforcing plates. A metal pull rope is fixedly connected to one side of the push plate. The metal pull rope moves through a through hole. Mounting frames are symmetrically fixedly installed inside the base pedal and the auxiliary pedal. Multiple pulleys are rotatably connected inside the mounting frames.

[0015] Preferably, the metal pull ropes pass over multiple pulleys, and a pull ring is fixedly connected between two metal pull ropes located on the same side. Slide rods are symmetrically fixedly installed on the other side surface of the reinforcing plate. Multiple slide rods slide through the base plate pedal and the auxiliary plate respectively, and springs are movably sleeved on the outside of the slide rods.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] 1. When the auxiliary pedal is raised, the first and second support plates flip to adapt to the lifting distance of the auxiliary pedal. Through the engagement of the pawl and ratchet, the auxiliary pedal is fixed after being raised. Thus, by raising the auxiliary pedal, the person can step on the auxiliary pedal after stepping on the base pedal to enter the cab. While maintaining the distance between the door pedal and the ground, the distance between the door pedal and the cab is shortened, making it easier for shorter people to enter the cab. In addition, the limiting component allows the auxiliary pedal to be fixed at different heights, making the door pedal structure more convenient to use.

[0018] 2. Pull the metal cord to move the push plate, causing the pawl to separate from the ratchet, allowing the second connecting shaft to rotate freely, and enabling the auxiliary pedal to move down. The height of the auxiliary pedal can be freely adjusted. Through the pull ring, the metal cords on both sides can simultaneously move the push plate, causing multiple pawls to separate from the ratchet at the same time, making the height of the auxiliary pedal easy to adjust.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figure 1-5 In this embodiment of the utility model, a transportation vehicle door pedal structure includes a base pedal 1, an auxiliary pedal 102 movably mounted above the base pedal 1, protective frames 101 symmetrically fixedly mounted on both sides of the base pedal 1, and multiple connecting ears 103 fixedly mounted on the inner side of the base pedal 1. Through holes 104 are provided on both sides of the base pedal 1 and the auxiliary pedal 102. The base pedal 1 is fixed at the vehicle front mounting position via the connecting ears 103. A support assembly 2 is movably mounted between the base pedal 1 and the auxiliary pedal 102. The support assembly 2 includes two first support plates 204 movably mounted between the base pedal 1 and the auxiliary pedal 102, with a second support plate 205 hinged to one end of each first support plate 204. Two limiting components 3 are respectively fixedly mounted on one side of the base pedal 1 and the auxiliary pedal 102. The limiting component 3 includes a push plate 302, with pawls 303 symmetrically fixedly mounted on one side of the push plate 302.

[0027] Specifically, the auxiliary pedal 102 is lifted by the support component 2, allowing personnel to step on the base pedal 1 and the auxiliary pedal 102 to enter the driver's cab. Then, the support height of the support component 2 is limited by the limiting component 3.

[0028] Example 1

[0029] like Figure 1-3 As shown, in this embodiment, a first connecting seat 201 is symmetrically fixedly installed on the inner side of the auxiliary pedal 102, and a second connecting seat 202 is symmetrically fixedly installed on the inner surface of the base pedal 1. A rotating shaft 203 is rotatably connected inside both the first connecting seat 201 and the second connecting seat 202. The rotating shaft 203 inside the first connecting seat 201 is fixedly connected to the first support plate 204 at the corresponding position, and the rotating shaft 203 inside the second connecting seat 202 is fixedly connected to the second support plate 205 at the corresponding position. A first connecting shaft 206 is fixedly connected to one end of the two second support plates 205, and a second connecting shaft 207 is fixedly connected between the two rotating shafts 203 on the same side. A ratchet 208 is symmetrically fixedly installed on the outer surface of the second connecting shaft 207, and the pawl 303 and the ratchet 208 are movably engaged.

[0030] In this embodiment, when the auxiliary pedal 102 is raised, the pivot 203 and the first connecting seat 201 are rotatably connected to the second connecting seat 202. Simultaneously, the hinge of the first support plate 204 and the second support plate 205 allows them to rotate, adapting to the lifting distance of the auxiliary pedal 102. The engagement of the pawl 303 and the ratchet 208 secures the raised auxiliary pedal 102. Thus, by raising the auxiliary pedal 102 upwards, a person can step on it. After stepping on the auxiliary pedal 102 above the base pedal 1, one enters the driver's cab. While maintaining the distance between the door pedal and the ground, the distance between the door pedal and the driver's cab is shortened, making it easier for shorter people to enter the driver's cab. The auxiliary pedal 102 can be fixed at different heights through the limiting component 3, making the door pedal structure easier to use. The stability of the first support plate 204 and the second support plate 205 is increased through the first connecting shaft 206 and the second connecting shaft 207.

[0031] like Figure 4 and Figure 5 As shown, in this embodiment, reinforcing plates 301 are symmetrically fixedly installed on both sides of the inner surface of the base pedal 1 and the auxiliary pedal 102. The push plate 302 slides and fits against the reinforcing plate 301. A metal pull rope 306 is fixedly connected to one side of the push plate 302. The metal pull rope 306 moves through the through hole 104. Mounting brackets 308 are symmetrically fixedly installed inside the base pedal 1 and the auxiliary pedal 102. Multiple pulleys 309 are rotatably connected inside the mounting brackets 308.

[0032] In practice, pulling the metal pull rope 306 causes the push plate 302 to move, which separates the pawl 303 from the ratchet 208, allowing the second connecting shaft 207 to rotate freely, and the auxiliary pedal 102 to move down, thus freely adjusting the height of the auxiliary pedal 102.

[0033] Example 2

[0034] Based on Embodiment 1, in order to overcome the problem that multiple pawls 303 are not convenient to operate simultaneously.

[0035] like Figure 5 As shown, in this embodiment, the metal pull rope 306 passes around multiple pulleys 309, and a pull ring 307 is fixedly connected between two metal pull ropes 306 located on the same side. Slide rods 304 are symmetrically fixedly installed on the other side surface of the reinforcing plate 301. Multiple slide rods 304 slide through the base plate pedal 1 and the auxiliary pedal 102 respectively. A spring 305 is movably sleeved on the outside of the slide rod 304.

[0036] In practice, the pulley 309 rotates to reduce the friction of the metal pull rope 306. The pull ring 307 enables the metal pull ropes 306 on both sides to move the push plate 302 simultaneously, so that multiple pawls 303 can be separated from the ratchet 208 at the same time, making it easy to adjust the height of the auxiliary pedal 102.

[0037] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0038] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
