Description

Technical Field

[0001] This invention relates to the field of vehicle entry and exit assistance devices, specifically to a collision-resistant pedal for engineering vehicles. Background Technology

[0002] Construction vehicles have high chassis and a high cab floor, resulting in high handrails and making it difficult to get in and out. This is usually addressed by increasing the number of steps and lowering their height. However, while lower steps make it easier for people to get in and out of the cab, construction vehicles often operate in poor road conditions, making these lower steps more susceptible to damage from impacts.

[0003] Chinese Patent Publication No. CN114537284A discloses a movable pedal device for an engineering vehicle, comprising: a pedal body, an upper anti-slip pedal, a transition bracket, a pedal connecting bracket welding assembly, and a movable pedal assembly. The pedal body is provided with a pedal groove, and the upper anti-slip pedal is disposed in the pedal groove of the pedal body. The upper end of the transition bracket is connected to the pedal body, and the lower end of the transition bracket is connected to the pedal connecting bracket welding assembly. The upper part of the pedal connecting bracket welding assembly is provided with a mounting base, and the pedal connecting bracket welding assembly is connected to the vehicle frame through the mounting base. The upper end of the movable pedal assembly is connected to the lower end of the pedal connecting bracket welding assembly.

[0004] While the aforementioned technology can improve the passability of engineering vehicles through the flexible deformation of the belt, the flexible belt is prone to significant swaying and shaking, especially from side to side, when stepped on by people getting on and off the vehicle, which seriously affects the comfort and safety of people getting on and off the cab.

[0005] Therefore, impact-resistant pedals for engineering vehicles were proposed. Summary of the Invention

[0006] The purpose of this invention includes providing a shock-resistant pedal for engineering vehicles that is less prone to shaking after being stepped on, making it more comfortable and safer to use.

[0007] To achieve the above objectives, the present invention provides the following technical solution:

[0008] This invention provides a collision-resistant pedal for engineering vehicles, comprising a micro-rotating pedal, a left connector, a right connector, and an upper connector.

[0009] Rigid side plates are rotatably connected to both the left and right connectors. The sides of the left and right connectors are connected to the ends of the micro-rotation pedal in a front-to-back rotation manner. A front support block and a rear support block are provided sequentially from front to back on the lower part of the surface of the left and right connectors facing the micro-rotation pedal. The front support block is used to limit the degree of downward rotation of the front part of the micro-rotation pedal, and the rear support block is used to limit the degree of downward rotation of the rear part of the micro-rotation pedal.

[0010] The upper right side of the rigid side plate is rotatably connected to the lower side of the upper connector, and the upper end of the rigid side plate is in vertical contact with the lower side of the upper connector (this arrangement is used to limit the rigid side plate from swinging clockwise from a vertical state). The upper connector is used to connect the present invention to the fixed pedal.

[0011] Preferably, at least one of the left connector and the right connector is rotatably connected to the lower left side of the rigid side plate, and the lower end of the rigid side plate is in perpendicular contact with the upper surface of the left connector and / or the right connector.

[0012] Preferably, the micro-rotating pedal includes a plate body, the plate body having anti-slip texture and an arc-shaped anti-slip strip on its surface. The arc-shaped anti-slip strip is located at the front of the plate body, and its height is greater than the rear height of the plate body. The side of the plate body has a shaft hole, which is perpendicular to the side of the plate body and close to the front of the plate body. (In this way, when the micro-rotating pedal is not stepped on, under its own weight, the lower rear part of the micro-rotating pedal can rotate downward to contact the upper part of the rear support block, and the lower front part of the micro-rotating pedal moves away from the front support block and remains in this state. In this state, the upper ends of both ends of the micro-rotating pedal are not higher than the upper parts of the left and right connectors, the upper ends of the micro-rotating pedal are not engaged in the lower part of the rigid side plate, and the ends of the micro-rotating pedal will not abut against the rigid side plate. When the rigid side plate and / or the left connector are subjected to a rightward force, the rigid side plate can swing counterclockwise. At the same time, the left connector, the micro-rotating pedal, and the right connector can move to the right and upward.)

[0013] Preferably, the rear right side of the plate body is provided with a rear protrusion, and a vertical stop is connected to the right side of the rear protrusion. The stop is close to the left rear edge of the rigid side plate on the right side.

[0014] Preferably, the stop block is provided with a chamfer near the edge of the right rigid side plate, and / or the rear left end of the plate body, the chamfer including a bevel, to guide the stop block and the plate body to move more easily to the opposite face of the rigid side plate.

[0015] Preferably, the surface of the arc-shaped anti-slip strip is provided with anti-slip cones.

[0016] Preferably, the end face of the arc-shaped anti-slip strip is semi-circular.

[0017] Preferably, a load-bearing shaft is vertically fixed between the opposing faces of the left connector and the right connector, and the load-bearing shaft is used to rotatably connect to the shaft hole.

[0018] Preferably, a magnet is connected to the rear support block and / or the rigid side plate. The magnet is used to enhance the stability of the rear part of the micro-rotation pedal in contact with the rear support block and to enhance the stability of the angle between the rigid side plate and the plate body.

[0019] Preferably, at least one end of the rear lower part of the plate body is connected to a ferromagnetic material (such as an iron sheet) for attracting magnets.

[0020] Preferably, the left side of the left connector is an inclined surface facing downwards.

[0021] Preferably, the impact-resistant pedal for engineering vehicles further includes a rubber sheet for cushioning impact forces and further protecting the present invention, the upper edge of which is connected to the left side of a rigid side plate connected to the left connector.

[0022] Preferably, the rubber sheet is reinforced with fabric, tension lines, or other materials inside and / or on the outside.

[0023] Preferably, the upper connector is formed by connecting an ear plate to one side of the angle steel and having at least two holes on the other side.

[0024] Due to the adoption of the above technical solutions, the advantages of this invention are as follows:

[0025] 1. When the present invention is installed under the fixed pedal of an engineering vehicle, neither end of the micro-rotating pedal is higher than the top of the left and right connectors during vehicle operation. The end of the micro-rotating pedal and the stop block will not come into contact with the rigid side plate. Therefore, if an obstacle hits the rigid side plate and / or the left connector during vehicle operation, the rigid side plate can swing counterclockwise. At the same time, the left connector, the micro-rotating pedal and the right connector can move to the right and upward, making the impact-resistant pedal provided by the present invention less prone to damage from impacts and improving the passability of engineering vehicles.

[0026] 2. This invention can remain stable during use by people stepping on it, and is not easy to sway or shake, so as to achieve a more stable, comfortable and safe use process.

[0027] 3. The end face of the arc-shaped anti-slip strip provided by the present invention is semi-circular and its height is greater than the height of the rear side of the plate body. This ensures that after the micro-rotation pedal is stepped on, the arc-shaped anti-slip strip on the front part of the micro-rotation pedal is always higher than the rear part of the plate body, making it less likely for people getting on and off the vehicle to slip forward and fall off the pedal.

[0028] 4. The present invention has a rubber sheet connected to the left side of the rigid side plate on the left side, which is beneficial to further buffer and reduce the impact and wear of obstacles on the present invention.

[0029] 5. The present invention has a simple structure, low cost, convenient installation, and good applicability. Attached Figure Description

[0044] In the description of this invention, it should be noted that if terms such as "upper," "lower," "inner," "outer," "left," "right," "front," and "rear" are used to indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship in which the product of this invention is usually placed during use, they are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this invention.

[0045] It should be noted that, where there is no conflict, the features in the embodiments of the present invention can be combined with each other.

[0046] The specific implementation method is described below:

[0047] Example 1 of the impact-resistant pedal for engineering vehicles provided by this invention, see [link to example]. Figure 1 , Figure 2 , Figure 5 It includes two upper connectors 10, two rigid side plates 20, a left connector 30, a right connector 40, a load-bearing shaft 6 vertically fixed between the sides of the left connector 30 and the right connector 40, and a micro-rotation pedal 50 rotatably connected to the load-bearing shaft 6.

[0048] The upper right sides of the two rigid side plates 20 are rotatably connected to the lower part of one upper connector 10. Magnets 8 (which can be replaced with springs) for magnetically attracting the upper connector 10 are connected to the upper ends of the two rigid side plates 20. The upper ends of the two rigid side plates 20 are in perpendicular contact with the lower part of one upper connector 10. The lower left sides of the two rigid side plates 20 are rotatably connected to the upper parts of the left connector 30 and right connector 40, respectively. The lower ends of the two rigid side plates 20 are in perpendicular contact with the upper parts of the left connector 30 and right connector 40, respectively. See [reference needed]. Figure 1 , Figure 8 , Figure 9 .

[0049] The left side of the left connector 30 is an inclined surface facing downwards. The lower parts of the surfaces of the left connector 30 and the right connector 40 facing the end face of the micro-rotation pedal 50 are sequentially fixedly connected from front to back to a front support block 3 and a rear support block 4. A magnet 8 is connected to the top of the rear support block 4. (See [reference]). Figure 1 , Figure 3 , Figure 4 .

[0050] The micro-rotating pedal 50 includes a plate body 51. The top of the plate body 51 is flush with the top of the left connector 30 and the right connector 40. The top of the plate body 51 is provided with anti-slip texture 54 and arc-shaped anti-slip strip 55. The arc-shaped anti-slip strip 55 is located at the front of the plate body 51, and the height of the arc-shaped anti-slip strip 55 is greater than the height of the rear of the plate body 51. The side of the plate body 51 is provided with a shaft hole 53 for rotatably connecting the load-bearing shaft 6. The shaft hole 53 is perpendicular to the side of the plate body 51 and close to the front of the plate body 51. Ferromagnetic bodies 9 for magnetically attracting magnets 8 on the rear support block 4 are connected to the lower rear of the plate body 51 on both sides. The right rear of the plate body 51 is provided with a rear protrusion 52. A vertical stop block 60 is connected to the right side of the rear protrusion 52. The stop block 60 is close to the left rear edge of the rigid side plate 20 on the right side. See Figure 1 , Figure 2 , Figure 5 , Figure 6 , Figure 7 .

[0051] In this embodiment, the load-bearing shaft 6 is close to the front support block 3; the upper connector 10 is formed by vertically connecting the ear plate 7 to one side of the angle steel and setting 3 holes 2 on the other side, the holes 2 are used to connect the fixed pedal 200 on the engineering vehicle through bolts 5; the surface of the arc anti-slip strip 55 is provided with anti-slip cones 551; the stop block 60 is provided with a chamfer 70 near the edge of the right rigid side plate 20 and the rear left end of the plate body 51; the ferromagnetic body 9 is an iron sheet; the micro-rotation pedal 50 is made of fiber-reinforced nylon.

[0052] The second embodiment of the impact-resistant pedal 100 for engineering vehicles provided by this invention differs from the first embodiment in that a rubber sheet 80 is connected to the left side of the rigid side plate 20, which is connected to the left connector 30, by bolts 5. This further enhances the impact resistance of the invention. See [link to relevant documentation]. Figure 12 .

[0053] During installation, the upper connector 10 is connected to the fixed pedal 200 of the engineering vehicle by means of bolts 5 or welding, and the two rigid side plates 20 are kept parallel.

[0054] When using this invention, the person can simply step on the slightly rotating pedal 50 up or down, just like stepping on the fixed pedal 200 when getting on or off the vehicle.

[0055] The principle behind this invention is that the pedal does not wobble easily when passengers are getting on or off the vehicle by slightly rotating it by 50 degrees:

[0056] Before the micro-rotating pedal 50 is stepped on, the angle between the rigid side plate 20 and the plate body 51 remains unchanged (the magnetic attraction provided by the magnet 8 further strengthens this state). When the micro-rotating pedal 50 is stepped on, since the main force-bearing position of the micro-rotating pedal 50 is always at the front of the plate body 51, the front of the micro-rotating pedal 50 rotates down around the load-bearing shaft 6 to contact the front support block 3. At the same time, the rear of the micro-rotating pedal 50 leaves the rear support block 4 and rotates up to a part of the left rear end of the plate body 51 that is above the left connector 30 and abuts against the lower right side surface of the rigid side plate 20 on the left. At the same time, the stop block 60 located at the right rear of the plate body 51 also moves to abut against the lower left side surface of the rigid side plate 20 on the right, thus restricting the rightward swing of the rigid side plate 20. Furthermore, since the clockwise swing of the rigid side plate 20 from the vertical state is restricted, the forward and backward swing is also restricted by the shaft 1. Therefore, the impact-resistant pedal provided by the present invention can remain stable during use by personnel, is not easy to sway or shake, and achieves a more stable, comfortable and safe use process.

[0057] The principle behind this invention's impact resistance:

[0058] When the micro-rotating pedal 50 is not pressed, under its own weight and the action of the magnet 8 on the rear support block 4, the end face of the plate body 51 and the stop block 60 do not contact the rigid side plate 20. During the vehicle's forward movement, if an obstacle hits the rigid side plate 20 and / or the left connector 30, the rigid side plate 20 can swing counterclockwise. At the same time, the left connector 30, the micro-rotating pedal 50 and the right connector 40 can move to the right and upward, making the impact-resistant pedal provided by the present invention less susceptible to damage from impacts. Furthermore, the impact resistance is further improved by the buffer shielding of the rubber sheet 80.

[0059] The above embodiments of the present invention are merely examples for clearly illustrating the present invention and are not intended to limit the implementation of the present invention. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is impossible to exhaustively list all possible implementations here. All obvious variations or modifications derived from the technical solutions of the present invention are still within the protection scope of the present invention.
