Description

Technical Field

[0001] This utility model relates to the field of pedal technology, specifically to an adjustable pedal with adjustable pressing force. Background Technology

[0002] A pedal is a common mechanical device, typically used as a control component to achieve specific functions through foot pressure. Below is a detailed description of the pedal's structural components: Pedal Body: This is the part that directly contacts the foot. Its shape and size vary depending on the application. It is generally made of a sturdy material with a certain degree of friction, such as metal, plastic, or rubber, to prevent slipping and ensure operational safety and stability. Support Components: These connect the pedal body to the main body of the device, bearing the force generated during pedaling and transmitting it to the corresponding mechanical structure or sensor. Support components typically consist of metal rods, brackets, or pivots. Their design ensures the pedal can rotate or move up and down flexibly, while possessing sufficient strength and stability to withstand repeated pedaling. Return Mechanism: Common return mechanisms include springs and elastic rubber. When the pedaling force is released, the return mechanism allows the pedal to quickly return to its initial position, ready for the next operation. The spring constant can be selected based on the required return force of the pedal to ensure a smooth feel and responsiveness during operation. Transmission or sensing components: In some applications, the movement of the pedal needs to be transmitted to other components through a transmission mechanism (such as a linkage, chain, gear, etc.) to achieve control of the equipment; or the pedal pressing action is converted into an electrical signal by a sensor (such as a pressure sensor, displacement sensor, etc.) and transmitted to the control system for processing and feedback.

[0003] Existing technology, such as publication number CN201677748U, provides a pedal, including a pedal rod and a foot plate connected to the pedal rod. A support shaft, rotatably supported on the foot plate, is provided at the end face where the foot plate connects to the pedal rod. The support shaft is fixedly connected to the pedal rod. A spring is sleeved on the support shaft to reset the foot plate. The foot plate can rotate relative to the support shaft. Compared with existing pedals, this invention sets the foot plate and pedal rod in a structure that allows relative rotation at a certain angle. When the driver presses the foot plate, the spring automatically adjusts the driver's foot position for comfort, improving driving comfort and reducing driver fatigue.

[0004] In existing technologies, pedals typically incorporate a rebound mechanism, creating resistance when the pedal is pressed down. However, individual foot strength varies, and if repeated pressing is required, it can be quite strenuous for users with insufficient strength to press down on pedals with higher resistance. Therefore, we propose an adjustable pedal design. Utility Model Content

[0005] The purpose of this utility model is to provide an adjustable pedal that solves the problem in the prior art where repeated pressing of the pedal is required, which is difficult for users with insufficient strength to press down the pedal when the pedal has high resistance.

[0010] Preferably, the adjustment mechanism includes two slides, which are fixedly connected to both sides of the top of the inner wall of the base, and the outer walls of the two slides are slidably connected with sliding buckles, which are fixedly connected to one end of the top of the corresponding tension spring.

[0011] Preferably, the sliding buckle has a corresponding position adjustment hole on the slide rail, and the slide rail has four adjustment holes. A rod is inserted into the adjustment hole at the corresponding position on the sliding buckle and the slide rail.

[0012] Preferably, the outer wall of the insertion rod is slidably connected to a slider, and the slider is slidably connected to the side wall of the base through a groove.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] A pedal with adjustable pressure, such as Figure 1 - Figure 4As shown, the system includes a base 1, a pedal 2 hinged to the top front of the base 1, and an arc-shaped rod 22 fixedly connected to the bottom of the pedal 2. The arc-shaped rod 22 extends through the top of the base 1 into the interior of the base 1 and is slidably connected to the through-hole at the top of the base 1. A pressing rod 23 is fixedly connected to one end of the bottom of the arc-shaped rod 22. Tension springs 24 are fixedly installed at both ends of the outer wall of the pressing rod 23 for resetting the pedal 2. Adjustment mechanisms are provided on both sides of the top of the inner wall of the base 1 for adjusting the resistance of the pedal 2. An anti-slip pad 21 is fixedly connected to the surface of the pedal 2. The center of the circle coincides with the axis of the hinge of the pedal 2. The outer wall of the base 1 is fixedly connected with a skirt 3. The adjustment mechanism includes two slides 41. The two slides 41 are fixedly connected to the two sides of the top of the inner wall of the base 1. The outer walls of the two slides 41 are slidably connected with sliding buckles 42. The sliding buckles 42 are fixedly connected to one end of the top of the corresponding tension spring 24. The sliding buckles 42 and the slides 41 have corresponding position adjustment holes 43. There are four adjustment holes 43 on the slides 41. The sliding buckles 42 and the corresponding position adjustment holes 43 on the slides 41 have inserted rods 44.

[0026] In this embodiment, by placing the foot on the anti-slip pad 21 area of ​​the pedal 2 and pressing down, the pressure rod 23 sinks down to contact sensors such as pressure sensors and displacement sensors, which convert the action of pressing the pedal 2 into an electrical signal and transmit it to the control system for processing and feedback. In use, the initial tension length of the tension spring 24 can be changed by sliding the position of the sliding buckle 42 on the slide 41 and inserting the plug rod 44 into the corresponding position of the adjustment hole 43 on the slide 41, thereby adjusting the resistance when pressing down the pedal 2.

[0027] like Figure 3 , Figure 4 As shown, preferably, a slider 46 is slidably connected to the outer wall of the insertion rod 44. The slider 46 is slidably connected to the side wall of the base 1 through a groove 45. A limiting frame 47 is fixedly connected to the side of the slider 46 outside the base 1. A limiting block 471 is slidably connected to the inner wall of the limiting frame 47, and the limiting block 471 is fixedly connected to the outer wall of the insertion rod 44. A spring 472 is movably sleeved on the outer wall of the insertion rod 44 at the position between the limiting block 471 and the inner wall of the limiting frame 47, and the limiting block 471 abuts against one side of the slider 46.

[0028] In this embodiment, the insertion rod 44 is pulled out from the adjustment hole 43 on the slide rail 41, and the slider 46 is pushed to slide in the slide groove 45, thereby causing the sliding buckle 42 connected to the insertion rod 44 in the slider 46 to move together, so as to facilitate moving to the adjustment hole 43 at the appropriate position, inserting the insertion rod 44, and adjusting the resistance when the pedal 2 is pressed down.

[0029] like Figure 1 , Figure 2As shown, preferably, a sliding frame 48 is fixedly connected to the base 1 at a position outside the sliding groove 45, and a protective cover 49 slides on the inner wall of the sliding frame 48.

[0030] In this embodiment, a sliding connecting cover 49 is provided on the inner wall of the sliding frame 48 so that the area of ​​the plug rod 44 can be covered by the sliding cover 49 when not in use, so as to protect the area of ​​the plug rod 44 and avoid accidental contact when no adjustment is needed.

[0031] This utility model discloses an adjustable pedal. When in use, the foot is placed on the anti-slip pad 21 area of ​​the pedal 2 and pressed down. This causes the pressure rod 23 to sink, contacting sensors such as pressure sensors and displacement sensors. The action of pressing the pedal 2 is converted into an electrical signal and transmitted to the control system for processing and feedback. During use, the insertion rod 44 is pulled out from the adjustment hole 43 on the slide rail 41, pushing the slider 46 to slide within the slide groove 45. This causes the sliding buckle 42 connected to the insertion rod 44 within the slider 46 to move together, facilitating movement to the appropriate position of the adjustment hole 43. The insertion rod 44 is then inserted to adjust the resistance when the pedal 2 is pressed down, thereby changing the initial tension length of the tension spring 24. A sliding protective cover 49 is provided on the inner wall of the slide frame 48 to cover the area of ​​the insertion rod 44 when not in use, thus protecting the area of ​​the insertion rod 44.
