Description

Technical Field

[0001] This utility model relates to the field of automotive pedals, and in particular to a concealed metal structure flip pedal. Background Technology

[0002] In vehicles such as off-road vehicles and pickup trucks, because the rear of the vehicle is relatively high off the ground, a step is usually installed at the rear of the vehicle to facilitate users getting in and out. Currently, the main method is to use a bracket + bolt structure to fix the step. The disadvantage of this method is that the step is fixed at the rear of the vehicle for a long time, taking up a lot of space when not in use, and the bottom of the step is likely to touch the ground when the vehicle is in motion. Another method uses a pin connection structure, but the disadvantages of this method are that the whole structure is heavy, it is difficult to achieve positioning, and the range of motion of the moving shaft fluctuates greatly.

[0003] The prior art (Announcement No.: CN110901543B, Announcement Date: 2025.05.02) discloses an automobile pedal, which, when stored, uses a torsion spring to push the first motion shaft towards the pedal and uses an elastic protrusion to lock into a concave hole for locking and positioning. However, when the vehicle is traveling at high speed, due to the diversity of road conditions, the locking mechanism relying on the elastic stress of the torsion spring and the elastic protrusion is not secure enough. If the elastic stress is increased, although a stable locking mechanism can be achieved, it will be very difficult to unfold, making it inconvenient to use. In addition, the torsion spring continuously provides upward rotational elastic stress to the first motion shaft, requiring an additional positioning device for fixation during unfolding. The positioning device has a complex structure and is not easy to manufacture and assemble.

[0004] In the prior art (Announcement No.: CN221757436U, Announcement Date: 2024.09.24), a foldable boarding step is also disclosed. This design uses a sliding connection where one end of the step assembly is slidably connected to the slide rail assembly. This allows the step assembly to be easily pulled out or retracted from the slide rail assembly, and it can be secured by a locking mechanism after retraction, preventing it from sliding out while the vehicle is in motion. However, when the step slides along the slide rails on both sides, it is prone to misalignment and jamming, resulting in uneven sliding. Furthermore, the upper edges of the two slide rails lack a fixing structure, relying solely on the reinforcing beams at the bottom for reinforcement. After prolonged use, the upper edges of the slide rails on both sides will deform outwards, causing the step to loosen and resulting in low stability. Additionally, there is no limiting structure when the step is unfolded, and the coordination of various mechanisms can easily loosen due to stepping, leading to poor safety when getting on and off the vehicle.

The two ends of the first positioning shaft are respectively fixedly installed at the front and rear ends of the left side of the hinge bracket, and the two ends of the second positioning shaft are respectively fixedly installed between the two support rods.

[0008] Furthermore: the sector-shaped positioning plate is fixedly installed at the front end of the second positioning shaft, the sector-shaped positioning plate is formed with a positioning notch, and the front side of the first connecting plate is formed with a positioning protrusion, the positioning protrusion being inserted into the positioning notch with a clearance fit.

[0009] Furthermore, the upper left end of each of the two support rods is formed with a first arc-shaped groove, and when the folding pedal is unfolded, the first arc-shaped grooves at the upper end of the two support rods press against the first positioning cylinder outside the first positioning shaft.

[0010] Furthermore, the lower ends of the left sides of both support rods are formed with second arc-shaped grooves. When the folding pedal is stored, the second positioning cylinder outside the second positioning shaft abuts against the second arc-shaped grooves at the lower ends of the two support rods.

[0011] Furthermore: the second connecting member includes a third positioning shaft, a fourth positioning shaft, and a second connecting plate.

[0012] Compared with the prior art, the beneficial effects of this utility model are: 1. Stable positioning and easy to use: This utility model does not use torsion springs for positioning. It is fixed by the limiting hole of the fan-shaped positioning plate and the positioning pin. The folding pedal will not loosen during vehicle operation. The unfolded and folded states can be switched by inserting and removing the positioning pin. It is effortless. Moreover, the positioning protrusion and positioning notch can make the limiting hole accurately align with the pin hole, so that the positioning pin will not be unable to be inserted.

[0013] 2. Space-saving and fits the vehicle body: When folded, the second positioning cylinder can be inserted into the second arc-shaped groove of the support rod. In addition, the second connecting piece has a bent edge, so the pedal can fit tightly against the bottom of the car's rear rack without taking up extra space or scratching anything. When unfolded, the folded pedal is in a horizontal position, and the first positioning cylinder can be pressed into the first arc-shaped groove for support and load-bearing, making it convenient to step on it for loading and unloading.

[0014] 3. Sturdy and durable with high safety: The second connecting plate in this utility model has a first reinforcing rib, there is a second reinforcing rib between the pedal and the support rod, there is a third reinforcing rib at the bottom of the pedal, and there are reinforcing crossbars between the support rods, which can ensure its load-bearing capacity and prevent damage. Moreover, the metal material has the effect of resisting high and low temperatures and corrosion. The overflow hole on the folding pedal can drain water, preventing water accumulation, rust, or slipping.

[0015] 4. Easy to produce and maintain; This utility model has fewer parts and no complex precision components, resulting in lower mold costs during production, simpler processing, and easier assembly. Damaged individual parts, such as positioning pins, can also be replaced later without disassembling the entire pedal.

[0025] like Figure 1-6 As shown, the present invention provides a concealed metal structure flip pedal, which includes a car tail rack 1 and a folding pedal 2. The bottom side of the car tail rack 1 is fixedly installed with a hinge bracket 3. The left side of the hinge bracket 3 is rotatably fitted with a first connector 4. The upper side of the folding pedal 2 is fixedly installed with two support rods 5. The bottom end of the first connector 4 is rotatably fitted with the middle of the two support rods 5. A sector-shaped positioning plate 6 is fixedly installed on the front side of the bottom end of the first connector 4. Limiting holes 7 are formed on both the left and right sides of the sector-shaped positioning plate 6. A pin hole 8 is formed on the front support rod 5. A positioning pin 9 is movably installed in the pin hole 8. The positioning pin 9 is inserted into the pin hole 8 and one of the limiting holes 7 with a clearance fit. A second connector 10 is hinged between the right side of the hinge bracket 3 and the upper end of the support rod 5. The principle is as follows: by using the cooperation between the first connector 4 and the second connector 10 and the support rods 5 on both sides, the folding pedal can be unfolded and folded on the bottom side of the car tail rack 1. When unfolding and folding, the fan-shaped positioning plate 6 will rotate with the bottom end of the first connector 4 relative to the support rod 5. When it rotates to the unfolded and folded position, a limiting hole 7 will be aligned with the pin hole 8. At this time, the positioning pin 9 is inserted into the pin hole 8 and the limiting hole 7 to complete the positioning of the folding pedal 2 when unfolding and folding. There is no need to equip it with a complicated positioning device, which reduces production costs and improves assembly efficiency. Since the folding pedal 2 can be unfolded and folded after the positioning pin 9 is pulled out, it is also convenient for the actual use of the pedal.

[0026] Furthermore: the first connecting member 4 includes a first positioning shaft 41, a second positioning shaft 42, and a first connecting plate 43. The upper and lower edges of the first connecting plate 43 are each formed with a first positioning cylinder 44. The first positioning shaft 41 and the second positioning shaft 42 are respectively rotatably fitted into the first positioning cylinder 44. The two ends of the first positioning shaft 41 are respectively fixedly installed at the front and rear ends of the left side of the hinge bracket 3, and the two ends of the second positioning shaft 42 are respectively fixedly installed between the two support rods 5. This ensures a stable connection between the first connecting member 4 and the hinge bracket 3 and the two support rods 5.

[0027] Furthermore: the sector-shaped positioning plate 6 is fixedly installed at the front end of the second positioning shaft 42. The sector-shaped positioning plate 6 has a positioning notch 11 formed on it, and the front side of the first connecting plate 43 has a positioning protrusion 12 formed on it. The positioning protrusion 12 is inserted into the positioning notch 11 with a clearance fit. This allows the sector-shaped positioning plate 6 to rotate together with the first connecting plate 43. When it rotates to the extreme positions at both ends, the limiting holes 7 at both ends of the sector-shaped positioning plate 6 will align with the pin holes 8. Then, the positioning pins 9 are used for insertion and limiting, so as to fix it when unfolding and storing, so as to prevent it from automatically unfolding during vehicle operation and also prevent it from automatically storing when unfolded for use.

[0028] Furthermore, the upper ends of the left sides of the two support rods 5 are each formed with a first arc-shaped groove 13. When the folding pedal 2 is unfolded, the first arc-shaped grooves 13 at the upper ends of the two support rods 5 are pressed on the first positioning cylinder 44 outside the first positioning shaft 41. By pressing the first positioning shaft 41 into the first arc-shaped grooves 13 of the two support rods 5, the load-bearing and limiting functions of the folding pedal 2 when unfolded are achieved.

[0029] Furthermore, the lower ends of the left sides of both support rods 5 are formed with second arc-shaped grooves 14. When the folding pedal 2 is stored, the second positioning cylinder 104 outside the second positioning shaft 42 abuts against the second arc-shaped grooves 14 at the lower ends of the two support rods 5; thus, the folding pedal 2 is misaligned and avoids misalignment when stored, reducing the space occupied by the folding pedal 2 when stored.

[0030] Furthermore, the second connecting member 10 includes a third positioning shaft 101, a fourth positioning shaft 102, and a second connecting plate 103. The two sides of the second connecting plate 103 are each formed with a second positioning cylinder 104. The third positioning shaft 101 and the fourth positioning shaft 102 are rotatably fitted into the second positioning cylinder 104. The two ends of the third positioning shaft 101 are fixedly installed on the right end of the bottom side of the hinge bracket 3, and the two ends of the fourth positioning shaft 102 are fixedly installed on the upper ends of the two support rods 5. This enables a stable connection between the second connecting member 10 and the hinge bracket 3 and the two support rods 5.

[0031] Furthermore, the second connecting plate 103 has a bent edge 15 formed in the middle, which can further reduce the space occupied when folded and stored.

[0032] Furthermore, one or more first reinforcing ribs 16 are fixedly installed between the two sides of the bent edge 15 and the second connecting plate 103; this can strengthen the strength of the bent edge 15 of the second connecting plate 103 and prevent the second connecting plate 103 from breaking.

[0033] Furthermore, the folding pedal 2 and the support rod 5 form an obtuse angle shape, which allows the folding pedal 2 to be horizontal with respect to the ground when unfolded, facilitating practical use.

[0034] Furthermore, one or more second reinforcing ribs 17 are fixedly installed between the folding pedal 2 and the support rod 5, which can strengthen the connection between the folding pedal 2 and the support rod 5.

[0035] Furthermore, one or more third reinforcing ribs 18 are fixedly installed on the bottom side of the folding pedal 2, which can enhance the load-bearing capacity of the folding pedal 2.

[0036] Furthermore, the folding pedal 2 is formed with several overflow holes 19, which can effectively overflow water and prevent water accumulation on the folding pedal 2.

[0037] Furthermore, a positioning handle 20 is fixedly installed on the outer end of the positioning pin 9, which facilitates the insertion and removal of the positioning pin 9.

[0038] Furthermore, one or more reinforcing crossbars 21 are fixedly installed between the two support rods 5; this enhances the strength of the two support rods 5 and ensures their service life.

[0039] This embodiment does not impose any limitation on the shape, material, structure, etc. of this utility model. Any simple modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of this utility model shall fall within the protection scope of this utility model.
