Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of pedal, in particular to a damping type pedal structure. BACKGROUND

[0002] Pedal generally refers to the equipment installed on the edge of the car, the edge of the boat, the front of the bed, etc. for easy up and down, also refers to the special device for foot control on some appliances. On the installed equipment, it provides an important role, and is the most common equipment in the society, whether it is in the work field, entertainment field or living field. Of course, in order to the applicability of the pedal, according to the needs of various sites, the structure of the pedal also needs to be designed accordingly. Especially on the device for foot control, the structural performance of the pedal is very important for the applicability of control.

[0003] Chinese patent authorization announcement number: CN111183092A, authorization announcement date: May 19, 2020, discloses a rubber pedal structure, a rubber pedal component is installed on the pedal rod, and the pedal component and the pedal rod are fastened by a side component. The deficiency of this technical solution is that when using the rubber pedal, in the state of the pedal component, the upper part of the rubber is extruded, and the force on the upper part of the rubber can be released outward in the expandable space of the groove extending in the front and back direction on the upper surface of the upper part of the rubber. However, the structure of the groove here is not designed with a gas structure, so it is possible that in the process of extruding and compressing the upper part of the rubber, the upper part of the rubber will extend into the groove, so that the gas in the groove cannot be smoothly discharged, or the upper part of the rubber cannot continue to release the extrusion force due to the mutual contact of the extrusion extension structure, so that the pedal cannot work to release the force. The release of extrusion force is the effect of damping of the pedal, so if the force cannot be released smoothly, it will affect the damping effect of the pedal.

[0004] In summary, the structure for reducing the air cannot be discharged from the groove can be set to allow the extrusion force to be released smoothly. SUMMARY

The limiting shafts 8 are connected to the front and rear ends of the ventilation grooves 7 through the two hard blocks 25. Elastic shafts 26 are installed on the hard blocks 25, and the two hard blocks 25 are connected through the elastic shafts 26. A plurality of through holes 15 are evenly distributed on the elastic shafts 26, so that the gas in the ventilation grooves 7 can flow smoothly through the through holes 15.

[0036] Then, the connection between the side strap 2 and the foot pedal block, and the connection between the lower cover 3 and the foot pedal block need to be done. The structure of the side strap 2 is annular, and a plurality of ventilation openings 17 are provided on the side strap 2, which correspond one-to-one to the ventilation openings 16. A plurality of fasteners 9 are installed on the side strap 2, which are symmetrically arranged about the center point of the side strap 2. The fasteners 9 are provided with connecting holes 10. The rubber lower block 4 is provided with a mounting recess, and a plurality of connecting holes 11 are provided on the mounting recess, which correspond one-to-one to the connecting holes 10. The lower cover 3 is installed at the mounting recess, and two fastening members 13 are installed on the lower cover 3, which are symmetrically arranged at the left and right ends of the lower cover 3. The fastening members 13 are provided with connecting holes 14. Screws 12 are used to sequentially pass through the connecting holes 14, the connecting holes 10 and the connecting holes 11, so that the lower cover 3 and the side strap 2 are threadedly connected to the foot pedal block under the cooperation of the screws 12.

[0037] Then in the rubber under block 4 is also installed with connecting piece 21, connecting piece 21 is equipped with support hole 22, support hole 22 is equipped with mounting hole 24 and engagement slot 23, mounting hole 24 is placed in support hole 22, engagement slot 23 is placed in the lower end of support hole 22, here mounting hole 24 and engagement slot 23 are matched with foot pedal rod 6, then it is possible to let foot pedal rod 6 pass through mounting hole 24 and engagement slot 23 and be connected with foot pedal block, here because rubber under block 4 is equipped with middle space 19, the position of middle space 19 corresponds to the position of support hole 22, and small diameter hole 20 is arranged in middle space 19, the rubber under block 4 can form a contact portion protruding upward from the rubber upper block 1, the contact portion extends along the vehicle width direction, so that in the case of downward extrusion of the rubber upper block 1, the contact portion contacts the inner wall of the rubber upper block 1 to support the rubber upper block 1, limiting the collapse of the middle space 19, so that it is difficult for the vibration to be transmitted from the foot pedal rod 6 to the rubber upper block 1.

[0038] Then the pedal block can be used, when force on the pedal block, that is, to the rubber block 1 on the upper block to apply pressure, then the rubber block 1 on the upper block to the front and rear two ends of the air slot 7 has the effect of expansion and extension, this expansion and extension effect is to buffer the pressure on the rubber block 1, that is, to let the pedal block have the effect of reducing vibration, at the same time, the expansion and extension of the rubber block 1 also has the effect of air pressure on the air in the air slot 7, so that the air can be discharged to the top of the air slot 7 (limiting shaft 8 to reduce the probability of the expanded rubber block 1 blocking the top of the air slot 7), and can be discharged through the air outlet two 17 after the air outlet one 16, so as to achieve the purpose of reducing the probability of blocking the air discharge due to the extension of the pedal structure.

Then the rubber block 1 on the upper block is no longer pressed (reduce the pressure of the pedal work or the foot does not apply pressure to the rubber block 1 on the upper block), so that the rolling shaft can be turned inward under the limiting effect of the rotating hole, that is, the turning block 18 is turned inward to close the air outlet two 17, so as to avoid the external object entering the air outlet two 17 and affecting the air discharge work of the pedal block, so that the use of the pedal is always in the state of reducing vibration. When the pedal is stepped on, the front end of the foot can be blocked by the block 5 to reduce the probability of the foot separating from the front end of the pedal block. When the rubber block 1 on the upper block is no longer pressed, the extension part of the rubber block 1 is retracted due to the elastic effect of the elastic shaft 26, that is, the air slot 7 returns to the original state, and the ring sleeved on the through hole 15 of the elastic shaft 26 also reduces the probability that the ring is blocked and cannot ventilate when the rubber block 1 is extended under pressure.

[0039] The ring in the through hole 15 can be made of hard copper ring, and the elastic shaft 26 can be selected to use the spring sleeved rubber sleeve (the opening of the through hole 15 will not affect the elastic effect of the spring matched with the elastic effect of the rubber).
