Description

Technical Field

[0001] This utility model belongs to the field of engineering machinery technology, and more specifically, it relates to a flexible connection anti-collision foot pedal. Background Technology

[0002] Currently, excavators are widely used in major mines across China for mining and loading operations. These excavators need to travel on gravel surfaces and are frequently bumped by rocks. According to the standard requirements for the distance between the two foot pedals, foot pedal structures need to be installed close to the ground, which inevitably exposes the foot pedals to impacts.

[0003] In the existing technology, the foot pedal is fastened to the fixing screw seat welded on the lower frame by bolts. The foot pedal and the lower frame are rigidly connected. When the foot pedal is impacted, the instantaneous large impact force can easily cause the foot pedal fixing bolt to be cut off by shear force and fail. It can also cause the foot pedal to be deformed or even fail due to impact. These failures are the common failure modes of foot pedals reported by the actual market, which affect the safety of the driver when getting on and off the vehicle and the overall user experience of the machine. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a flexible connection anti-collision foot pedal.

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

[0006] A flexible-connected anti-collision foot pedal includes a foot pedal and a flexible connector for bearing the impact force during impact. One side of the flexible connector is mounted on the lower frame via a connector, and the other side of the flexible connector is connected to the foot pedal via a connector. The flexible connector is made of hard rubber.

[0007] Preferably, the flexible connector has an I-shaped structure.

[0008] Preferably, the flexible connector has a support column in the middle for bearing the impact force during impact, and the upper and lower ends of the support column are respectively extended with reinforcing ribs, and the front and rear ends of the reinforcing ribs are respectively extended with connecting plates.

[0009] Preferably, the foot pedal is a one-piece bent steel plate, and the two sides of the foot pedal are provided with arc structures to reduce impact damage.

[0010] Preferably, the connecting components are bolts and washers.

[0011] Preferably, the foot pedal is provided with a threaded hole one, and the flexible connector is provided with a threaded hole two corresponding to the threaded hole one. The bolt passes through the threaded hole two and the threaded hole one in sequence from the inside to the outside, and the bolt shank does not protrude from the foot pedal.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. The foot pedal and the lower frame are connected by a flexible connector. Since the flexible connector can be made of hard rubber material and is approximately rectangular in shape, with a long vertical direction and a short front-to-back direction, it can ensure a large rigidity in the vertical direction and meet the load-bearing capacity when people step on it. In addition, when the foot pedal is impacted, the flexible connector can effectively unload part of the impact load. The elastic deformation of the flexible connector can move the foot pedal away from the impacting object, thereby effectively avoiding impact damage to the foot pedal.

[0014] 2. The flexible connector is connected to the foot pedal and the lower frame by bolts. When the foot pedal is impacted, the bolt is buffered by the flexible connector to avoid shear failure. At the same time, the foot pedal has a threaded hole, which is connected to the flexible connector by bolts. The bolts are connected from the inside to the outside, and the screw does not protrude from the foot pedal to avoid the bolt being impacted.

[0015] 3. The flexible connector has a near-cylindrical flexible support column in the middle to withstand the impact force during impact, and the reinforcing ribs ensure the rigidity in the vertical direction to meet the needs of getting on and off the vehicle.

[0016] 4. The foot pedal is made of thick steel plate bent in one piece, which is wear-resistant and has a simple structure that is easy to process. At the same time, the foot pedal has a large arc structure on both sides, which can make the foot pedal slide and avoid the impact object when it is hit, thereby reducing impact damage.

[0017] In summary, this invention can effectively avoid bolt shearing failure and foot pedal collision deformation, thereby improving the service life of the foot pedal. Attached Figure Description

[0024] The present invention will be further described below through specific embodiments and in conjunction with the accompanying drawings.

[0025] Example 1:

[0026] like Figure 1-2 As shown, a flexible connection anti-collision foot pedal includes a foot pedal 1 and a flexible connector 2 for bearing the impact force when impacted. One side of the flexible connector 2 is installed on the lower frame 5 through a connector, and the other side of the flexible connector 2 is connected to the foot pedal 1 through a connector. The flexible connector 2 is made of hard rubber.

[0027] In this embodiment, the foot pedal 1 and the lower frame 5 are connected by a flexible connector 2. Since the flexible connector 2 can be made of hard rubber, it ensures high rigidity in the vertical direction, meeting the load-bearing capacity requirements when a person steps on it. Furthermore, when the foot pedal 1 is impacted, the flexible connector 2 effectively unloads part of the impact load. Through elastic deformation, the flexible connector 2 moves the foot pedal 1 away from the impacting object, effectively preventing impact damage. Simultaneously, the flexible connector 2 is connected to the foot pedal 1 and the lower frame 5 by bolts 3. When the foot pedal 1 is impacted, the bolts 3 are cushioned by the flexible connector 2, preventing shear failure. Therefore, this invention effectively avoids shear breakage of the bolts 3 and collision deformation of the foot pedal 1, improving the service life of the foot pedal 1.

[0028] Example 2:

[0029] like Figure 3-4 As shown, a flexible connection anti-collision foot pedal differs from Embodiment 1 in that the flexible connector 2 has an I-shaped structure, and a support column 22 for bearing the impact force during impact is provided in the middle of the flexible connector 2. The upper and lower ends of the support column 22 are respectively extended with reinforcing ribs 23, and the front and rear ends of the reinforcing ribs 23 are respectively extended with connecting plates 24.

[0030] Specifically, the flexible connector 2 has a nearly cylindrical flexible support column 22 in the middle to withstand impact forces during collisions, and rectangular reinforcing ribs 23 extending vertically to ensure the rigidity in the vertical direction meets the requirements for getting on and off the vehicle. Simultaneously, connecting plates 24 extend from both ends of the reinforcing ribs 23; the front connecting plate 24 connects to the foot pedal 1, and the rear connecting plate 24 connects to the lower frame 5. Figure 3 and Figure 4 These are two different structures of the flexible connector 2 in this embodiment.

[0031] like Figure 5As shown, the foot pedal 1 is a one-piece bent steel plate, and the two sides of the foot pedal 1 are provided with arc structures 11 to reduce impact damage. Specifically, the foot pedal 1 is made of a thick steel plate bent in one piece, which is wear-resistant and has a simple structure that is easy to process; at the same time, the large arc structures 11 on both sides of the foot pedal 1 can allow the foot pedal 1 to slide and avoid the impacting object when it is impacted, thereby reducing impact damage.

[0032] Furthermore, the connecting components are bolt 3 and washer 4. The foot pedal 1 has a threaded hole 12, and the flexible connecting component 2 has a threaded hole 21 corresponding to threaded hole 12. Bolt 3 passes through threaded hole 21 and threaded hole 12 sequentially from the inside out, and the bolt shank of bolt 3 does not protrude from the foot pedal 1. Specifically, bolt 3 connects from the inside out, and the bolt shank does not protrude from the foot pedal 1, thus preventing bolt 3 from being impacted.
