[0034] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without creative work fall within the scope of the present application.
[0035] With reference to Figure 1 - and Figure 6 An embodiment provided by the present application is a pedal structure of a hydraulic pilot foot valve, which comprises:
[0036] A pedal body 1 is used to provide an operation contact surface, and the pedal body 1 comprises a base 101 and a surface plate 102, the surface plate 102 is provided with an anti-skid assembly for improving the anti-skid performance, and the base 101 is provided with a drainage assembly for guiding water to drain out;
[0037] A top rod 2 is used to transmit the mechanical force of foot operation to a valve body 3;
[0038] The valve body 3 is used to receive the mechanical force transmitted by the top rod 2 and generate a corresponding hydraulic signal;
[0039] A buffer assembly 4 is used to slow down the movement speed of the top rod 2 and control the movement speed of a valve core, and the buffer assembly 4 is arranged between the lower end of the top rod 2 and the valve body 3.
[0040] Specifically, through the anti-skid assembly of the pedal body 1, in cooperation with the surface plate 102, when the operator steps on, the anti-skid strips 103 and the anti-skid grooves 104 on the top thereof increase the friction between the foot and the pedal, thereby achieving the effect of improving the operation safety and effectively preventing the foot from slipping; through the drainage assembly of the pedal body 1, in cooperation with the base 101, when liquid falls on the surface plate 102, the liquid flows into the inclined drainage groove 106 through the water inlet groove 105 and is then discharged from the drainage port 107, thereby achieving the effect of quickly draining the accumulated water and avoiding the accumulation of liquid to affect the operation performance, so that the pedal is suitable for wet or complex working conditions; through the buffer assembly 4, in cooperation with the top rod 2 and the valve body 3, when the operator steps on the pedal to make the top rod 2 transmit mechanical force, the buffer assembly 4 slows down the movement speed of the top rod 2, thereby controlling the movement speed of the valve core, and achieving the effect of accurately controlling the generation of hydraulic signal and ensuring the stable operation of the hydraulic pilot foot pedal valve. Among them, the top rod 2, the valve body 3 and the buffer assembly 4 are all prior art, the top rod 2 is a key component for transmitting mechanical force, located between the pedal body 1 and the valve body 3, and transmits the applied mechanical force downward to the valve body 3 through foot pedal operation. It is usually columnar in structure and is made of high-strength steel or other wear-resistant materials to withstand high-frequency force transmission and wear; the valve body 3 is a core control component in the hydraulic system, which drives the movement of the internal valve core by receiving the mechanical force transmitted by the top rod 2, and finally generates a hydraulic signal. Its internal structure usually includes valve core, spring, sealing element, etc. According to the change of the valve core position, the output signal of the hydraulic system is controlled to perform specific hydraulic actions (such as driving the brakes, suspension adjustment or clutch control of the vehicle, etc.); the buffer assembly 4 is an auxiliary device for slowing down the movement speed of the top rod 2, which is usually composed of a spring and a hydraulic damping device. It is installed between the top rod 2 and the valve body 3. The spring provides a rebound force for the top rod 2, so that it quickly returns to the initial position after operation is completed. The hydraulic damping device limits the rebound speed of the top rod 2 to avoid impact on the internal valve core of the valve body 3 when it quickly returns, thereby protecting the valve body 3 structure and prolonging the service life.
[0041] With reference to Figure 2 and Figure 3 , the anti-skid assembly includes a plurality of anti-skid strips 103, which are distributed at equal intervals along the length direction of the surface plate 102. The top of each anti-skid strip 103 is provided with a plurality of anti-skid grooves 104, which are rhombic or honeycomb textured structures. The anti-skid grooves 104 are used to enhance the anti-skid effect of the pedal body 1 during operation.
[0042] Specifically, through the anti-skid strips 103 in the anti-skid assembly, in cooperation with the anti-skid grooves 104, when the operator steps on the pedal, the anti-skid strips 103 provide basic friction force by being distributed at equal intervals along the length direction of the surface plate 102, and the rhombic or honeycomb texture of the anti-skid grooves 104 increases the contact area between the foot and the pedal and changes the direction of the friction force, thereby achieving the effect of effectively improving the anti-skid performance of the pedal and reducing the risk of the operator's foot slipping.
[0043] Referring to Figure 1 , Figure 4 , Figure 5 and Figure 6 , the drainage assembly comprises a drainage groove 106, which is arranged on the inner bottom wall of the base 101, and the drainage groove 106 is communicated with two water inlet grooves 105, which are arranged on the inner side of the surface plate 102, and the drainage groove 106 is communicated with a drainage port 107, which is arranged on the outer side of the base 101, and the drainage groove 106 is arranged in an inclined manner, and the drainage groove 106 is used for guiding the accumulated water to flow to the drainage port 107, and the drainage port 107 is used for guiding the accumulated water from the surface plate 102 to the outside of the pedal body 1.
[0044] Specifically, through the drainage groove 106 in the drainage assembly, in cooperation with the water inlet groove 105 and the drainage port 107, when the liquid falls on the surface plate 102, the water inlet groove 105 collects the liquid and introduces it into the drainage groove 106, and the inclined drainage groove 106 guides the accumulated water to flow to the drainage port 107 by gravity, and the drainage port 107 then discharges the accumulated water outside the pedal body 1, thereby realizing the effect of quickly and efficiently discharging the accumulated water in the pedal and avoiding the accumulation of water to affect the performance of the pedal and prolong the service life of the pedal.
[0045] Referring to Figure 4 , the outer periphery of the surface plate 102 is provided with a magnetic stripe 1010, and the magnetic stripe 1010 is adsorbed to the inner side of the base 101, which is used to enhance the connection stability between the surface plate 102 and the base 101.
[0046] Specifically, through the magnetic stripe 1010 on the outer periphery of the surface plate 102, in cooperation with the inner side of the base 101, during the assembly and daily use of the pedal, the magnetic stripe 1010 tightly adsorbs the inner side of the base 101 by its own magnetic force, thereby realizing the stable connection between the surface plate 102 and the base 101, effectively reducing the relative displacement between the two, reducing the risk of failure caused by loosening, and facilitating the replacement of the surface plate 102. Different surface materials (such as rubber and hard plastic) can be selected to simplify the maintenance and replacement operation and meet different working requirements.
[0047] Referring to Figure 4 and Figure 5 , the bottom corners of the surface plate 102 are fixedly connected with guide rods 108, and the top corners of the base 101 are provided with guide grooves 109, and the guide rods 108 are inserted and matched with the guide grooves 109.
[0048] Specifically, through the guide rods 108 at the bottom corners of the surface plate 102, in cooperation with the guide grooves 109 at the top corners of the base 101, during the assembly and use of the pedal, the guide rods 108 are precisely inserted along the guide grooves 109, thereby realizing the positioning of the relative positions of the surface plate 102 and the base 101, effectively limiting the deviation of the two, and ensuring the structural integrity and stability of the pedal.
[0049] Working principle: when the operator steps on the pedal body 1, the foot contacts the surface plate 102, and the surface plate 102 is provided with a plurality of anti-skid strips 103 which are distributed at equal intervals along the length direction of the surface plate 102, thereby increasing the friction between the foot and the pedal. The top of the anti-skid strip 103 is provided with a plurality of anti-skid grooves 104 which are in a diamond or honeycomb texture structure. This texture structure can further increase the contact area and friction between the foot and the anti-skid strip 103. When the foot has a tendency to slide on the pedal, the complex texture can effectively prevent the foot from sliding, thereby enhancing the anti-skid effect of the pedal body 1 during operation.
[0050] When liquid (such as rainwater, cleaning water, etc.) falls on the surface plate 102, the liquid will enter the drainage groove 106 in the inner bottom wall of the base 101 through the two water inlet grooves 105 on the inner side of the surface plate 102. The drainage groove 106 is arranged in an inclined manner. Under the action of gravity, the accumulated water will flow along the inclined drainage groove 106 to the drainage port 107. Finally, the accumulated water is discharged from the pedal body 1 through the drainage port 107, thereby avoiding the accumulation of liquid inside the pedal.
[0051] The magnetic strip 1010 and the inner side of the base 101 are mutually attracted, and this magnetic attraction can provide a stable connection force, so that the surface plate 102 can be closely attached to the base 101. At the same time, the guide rods 108 at the four corners of the bottom of the surface plate 102 are inserted and matched with the guide grooves 109 at the four corners of the top of the base 101. The cooperation of the guide rods 108 and the guide grooves 109 plays a role in positioning and auxiliary connection, limiting the displacement of the surface plate 102 relative to the base 101, and further enhancing the connection stability between the surface plate 102 and the base 101.
[0052] When the operator steps on the pedal body 1, the pedal body 1 is subjected to a downward pressure, and the movement of the pedal body 1 transmits mechanical force to the valve body 3 through the top rod 2. A buffer assembly 4 is arranged between the lower end of the top rod 2 and the valve body 3, which can slow down the movement speed of the top rod 2, thereby controlling the movement speed of the valve core. The valve core moves under the action of the mechanical force transmitted by the top rod 2, and the valve body 3 generates a corresponding hydraulic signal according to the movement of the valve core, so as to realize the function of the hydraulic pilot foot valve.
[0053] Finally, it should be noted that the above description is only a preferred embodiment of the present application and is not intended to limit the present application. Although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent replacements to some technical features, as long as they are within the spirit and principles of the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the present application shall be included in the protection scope of the present application.
