Description
Technical Field
[0001] This utility model relates to the field of large vehicle protection technology, specifically to a protective pedal for large vehicles. Background Technology
[0002] In the mining and transportation sector, mining trucks are the mainstay of heavy-duty transportation, and their safety and functionality are of paramount importance. Due to their unique working environment and tall body design, mining truck drivers face certain safety hazards when getting on, off, and during operation. This is especially true on the rugged roads of mining areas, where the stability and protective capabilities of mining trucks during operation are urgent issues to be addressed.
[0003] Traditional protective measures for mining trucks are mostly limited to fixed bumpers or simple pedal designs. While these designs offer some protection, their impact mitigation and maneuverability are insufficient during mining truck operation, especially when turning or encountering emergencies. Furthermore, the tall size of mining trucks makes it difficult for drivers to observe their surroundings, increasing the risk of collisions.
[0004] In response to the safety needs of mining trucks during operation, some improved protective pedal designs have emerged in the market in recent years. These designs, while providing basic convenience for getting on and off the truck, also attempt to enhance safety by adding anti-slip textures and adjusting the pedal angle. However, most of these designs remain at the level of static protection and fail to fully utilize the potential protective value of the pedals during operation. Utility Model Content
[0005] In view of this, the purpose of this utility model is to provide a special protective pedal for large vehicles to solve the technical problems mentioned in the background art.
[0006] This utility model is achieved through the following technical solution:
[0007] A protective step for large vehicles includes two symmetrically distributed fixed plates, both of which are installed on the bottom surface of the bumper on the front side of the mining truck. One end of each fixed plate is connected to the bottom surface of the bumper, and the other end extends downward. A fixed seat is provided on the front side of each fixed plate, and a support bar is connected to each fixed seat. One end of each support bar is movably connected to the fixed seat, and the other end extends outward. The support bar can rotate around the fixed seat as an axis. Multiple first step bars are connected between the two support bars, and the two ends of the multiple first step bars are respectively connected to the opposite sides of the two support bars. A connecting plate is provided on the outer side of each support bar, and a locking component is provided on each connecting plate for locking the support bar to rotate.
[0008] Furthermore, the snap-fit component includes two mounting plates, a torsion spring, a connecting rod, a snap-fit block, and a snap-fit groove. The two mounting plates are both installed on the top surface of the connecting plate and are symmetrically distributed. The torsion spring is located between the two mounting plates and is sleeved on the connecting rod. The snap-fit block is connected to one end of the connecting rod. The snap-fit groove is installed on the fixing plate, and the snap-fit block and the snap-fit groove are compatible.
[0009] Furthermore, both mounting plates are provided with connection holes, and one end of the torsion spring is provided with two torsion arms, which are respectively adapted to the two connection holes.
[0010] Furthermore, a limit block is connected to one end of the support bar near the fixed plate. The limit block is used to limit the rotation angle of the support bar.
[0011] Furthermore, multiple evenly distributed second pedal strips are connected between the multiple first pedal strips, and both the first pedal strips and the second pedal strips are provided with several evenly distributed recesses.
[0012] Furthermore, a fixing rod is provided between the two support bars, and multiple connecting blocks are connected between the fixing rod and one of the first pedal bars.
[0013] The beneficial effects of this utility model are as follows:
[0014] This is a special protective step for large vehicles. The support bar rotates around the fixed base, and during the rotation, multiple first step bars are simultaneously flipped. The first step bars, which were originally in the same horizontal position, are flipped into a folded state arranged vertically and are firmly fixed together by a snap-fit component. This transforms the first step into a guardrail. When the mining truck is turning or encountering an emergency, it can provide a certain degree of collision protection and buffering. When needed, the support bar rotates around the fixed base again, and the multiple first step bars are unfolded from the folded state.

[0025] Please see Figure 1-3This utility model provides a technical solution: a special protective pedal for large vehicles, including two symmetrically distributed fixed plates 1. Both fixed plates 1 are installed on the bottom surface of the bumper on the front side of the mining truck. One end of the fixed plate 1 is connected to the bottom surface of the bumper, and the other end extends downward. A fixed seat 2 is provided on the front side of both fixed plates 1. A support bar 3 is connected to both fixed seats 2. One end of the support bar 3 is movably connected to the fixed seat 2, and the other end extends outward. The support bar 3 can be rotated around the fixed seat 2. A plurality of first pedal strips 4 are connected between the two support bars 3. The two ends of the plurality of first pedal strips 4 are respectively connected to the opposite sides of the two support bars 3. A connecting plate 6 is provided on the outer side of both support bars 3. A snap-fit component 7 for snapping the support bar 3 to rotate is provided on both connecting plates 6.
[0026] In this technical solution, the support bar 3 is Z-shaped and consists of two horizontal plates and one vertical plate. Multiple first pedal bars 4 are installed between the horizontal plates at the bottom of the two support bars 3.
[0027] Before the mining truck is ready to start, the driver will operate the support bar 3 to rotate around the fixed seat 2. During the rotation of the support bar 3, multiple first pedal bars 4 will rotate synchronously, so that the first pedal bars 4, which were originally in the same horizontal position, will become vertical and parallel after rotating. They will be firmly fixed together by the locking component 7, thus turning the first pedals into guardrails. When the mining truck is turning or encountering an emergency, it can provide a certain degree of collision protection and buffer protection. When the driver needs to get on or off the truck, he can release the locking component and operate the support bar 3 to rotate around the fixed seat 2 again. As the support bar 3 rotates, the vertically parallel first pedal bars 4 will rotate synchronously again and return to the same horizontal plane, making it convenient for the driver to enter and exit.
[0028] The support bar 3 rotates around the fixed base 2, and during the rotation, the support bar 3 will rotate in conjunction with multiple first pedal bars 4 to flip synchronously. The first pedal bars 4, which were originally in the same horizontal position, will be folded up and down after flipping and are firmly fixed together by the snap-fit component 7, thereby converting the first pedals into guardrails. When the mining truck is turning or encountering an emergency, it can provide a certain degree of anti-collision and buffer protection. When it is needed, the support bar 3 will rotate around the fixed base 2 again, so that the multiple first pedals will change from the folded state to the unfolded state.
[0029] In this embodiment: the snap-fit component 7 includes two mounting plates 71, a torsion spring 72, a connecting rod 73, a snap-fit block 74 and a snap-fit groove 75. The two mounting plates 71 are both installed on the top surface of the connecting plate 6 and are symmetrically distributed. The torsion spring 72 is located between the two mounting plates 71 and is sleeved on the connecting rod 73. The snap-fit block 74 is connected to one end of the connecting rod 73. The snap-fit groove 75 is installed on the fixing plate 1, and the snap-fit block 74 and the snap-fit groove 75 are adapted to each other.
[0030] When the support bar 3 rotates around the fixed base 2, it simultaneously pulls the locking component 7 to flip. This flipping process continues until the locking block 74 contacts the preset slot 75 on the fixed plate 1. After that, if a pushing force is continued to be applied to the support bar 3, the slot 75 will exert a force on the locking block 74. This force will activate the torsion spring 72, causing it to drive the connecting rod 73 to retract. As the connecting rod 73 retracts, the locking block 74 will gradually penetrate deeper into the slot 75 until the two achieve a stable locking state. At this point, the support bar 3 is firmly fixed to the fixed base 2 and can no longer rotate.
[0031] In this embodiment: both mounting plates 71 are provided with connection holes 8, and one end of the torsion spring 72 is provided with two torsion arms, which are respectively adapted to the two connection holes 8.
[0032] When the torsion spring 72 contracts, the two torsion arms at the ends will generate circular motion or oscillation within the two connecting holes 8 respectively.
[0033] In this embodiment: a limiting block 9 is connected to one end of the support bar 3 near the fixing plate 1. The limiting block 9 is used to limit the flipping angle of the support bar 3.
[0034] When the first folding pedal 4 is about to be unfolded, the support bar 3 will begin to rotate around the center point of the fixed base 2. At the same time, the limiting block 9 will rotate synchronously with the rotation of the support bar 3. This rotating process will continue until the limiting block 9 contacts the rear side of the fixed plate 1. Once the limiting block 9 contacts the rear side of the fixed plate 1, it will play a limiting role, ensuring that the rotation angle of the support bar 3 is limited to the range of 80° to 90°.
[0035] In this embodiment: multiple first pedal strips 4 are connected by multiple evenly distributed second pedal strips 5, and both the first pedal strips 4 and the second pedal strips 5 are provided with a number of evenly distributed recesses 10.
[0036] Multiple first pedal strips 4 and multiple second pedal strips 5 are arranged in a crisscross pattern to increase the contact area of the user's feet. The recessed parts 10 are arc-shaped and there is a certain distance between the recessed parts 10, which ensures the stability of the user's footing and also plays a good anti-slip role.
[0037] In this embodiment: a fixing rod 11 is provided between the two support bars 3, and multiple connecting blocks 12 are connected between the fixing rod 11 and one of the first pedal bars 4.
[0038] The connecting block 12 can increase the support strength of the first pedal strip 4 and the second pedal strip 5. When the first pedal strip 4 and the second pedal strip 5 are subjected to pressure or impact, the connecting block 12 can act as an additional support point to help distribute and mitigate the impact of these forces on the first pedal strip 4 and the second pedal strip 5.
[0039] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
