Description

Technical Field

[0001] This invention relates to the field of automotive parts and accessories manufacturing technology, and more specifically, to an electric pedal with a soft start and soft stop function. Background Technology

[0002] In today's rapidly developing automotive industry, various SUVs and off-road vehicles are widely favored for their superior passability and spacious interiors. However, these vehicles generally have a high body, which makes it inconvenient for passengers to get in and out. To solve this problem, electric running boards have emerged as a convenient auxiliary device. They can automatically extend when the door is opened to provide support for getting in and out of the vehicle, and automatically retract and hide under the vehicle body after the door is closed, which does not affect the vehicle's passability and improves the convenience of use.

[0003] Existing electric pedals typically rely on drive components such as motors and gear sets to achieve telescopic movement. However, they have many shortcomings in practical applications. On the one hand, due to the power output characteristics of the drive components, electric pedals often lack a smooth transition at the moment of starting and stopping, resulting in sudden start or stop of the telescopic movement. This not only generates obvious impact noise, affecting the user experience, but also causes the drive components and connecting structures to bear large instantaneous stress for a long time, which can easily cause wear, deformation or even failure of components, seriously shortening the service life of electric pedals.

[0004] On the other hand, as an exposed component outside the vehicle, the electric pedal is easily covered with mud, snow, sand and other debris during use. When these debris accumulate to a certain extent, they will directly hinder the normal retraction of the electric pedal. At best, the pedal cannot be fully retracted to the hidden position, affecting the vehicle's appearance and driving safety. At worst, it may cause the drive components to jam or overload, leading to serious malfunctions such as motor burnout and gear breakage, which will significantly increase the maintenance cost and failure rate of the equipment.

[0005] Based on this, the present invention discloses an electric pedal with a soft start and soft stop function. Summary of the Invention

[0006] To address the issues raised in the background art, such as the lack of smooth transition during the start and stop of electric pedals due to the power output characteristics of the drive components, resulting in sudden start or stop of the extension / retraction action, causing the drive components and connecting structures to bear large instantaneous stress for a long time, which easily leads to wear, deformation, or even failure of the components, severely shortening the service life of the electric pedals, and the fact that electric pedals, as components exposed outside the vehicle, are easily contaminated with mud, snow, sand, and other debris during use, when these debris accumulate to a certain extent, they directly hinder the normal retraction action of the electric pedal. At best, this prevents the pedal from fully retracting to the hidden position, affecting the vehicle's appearance and driving safety; at worst, it may cause the drive components to jam or overload, leading to serious malfunctions such as motor burnout and gear breakage, significantly increasing the maintenance cost and failure rate of the equipment. This invention provides an electric pedal with a soft start and soft stop function, which includes two fixed shells.

The telescopic end of the electric telescopic rod is fixedly connected to the rack. Support plates are movably connected between the four swing arms within the same fixed housing near the pedal body. The bottom of the pedal body is fixedly connected to the tops of the two support plates.

[0009] Preferably, the buffer mechanism includes a horizontal plate, a lug, a horizontal tube, a horizontal bar, and a lever. A horizontal plate is fixedly connected between the two fixed shells away from the pedal body. Lugs are symmetrically fixedly connected to the bottom of the horizontal plate. A horizontal tube is fixedly connected between the two lugs. A horizontal bar is provided inside the horizontal tube. Both ends of the horizontal bar pass through the lugs and are movably connected to the lugs. A lever is fixedly connected to the outside of the horizontal bar with evenly distributed levers.

[0010] Preferably, the buffer mechanism further includes a driven gear and a transmission sector gear. The driven gear is fixedly connected to both ends of the crossbar. The end of the support shaft near the center of the two fixed housings away from the fixed housing passes through the inner ring of the bearing and is fixedly connected to the transmission sector gear. The transmission sector gear meshes with the driven gear.

[0011] Preferably, the concealed component includes a mounting shell, a movable block, a screw hole, a screw rod, and a drive motor. Each of the two fixed shells has a mounting shell at its end furthest from the horizontal plate. The side of each mounting shell opposite to the fixed shell is open. Movable blocks are symmetrically arranged inside the mounting shell. A screw hole is provided on one side of each movable block. A screw rod is installed between two adjacent screw holes. Both ends of the screw rod penetrate the mounting shell and are movably connected to it. A drive motor is installed on the side of the mounting shell furthest from the anti-slip mechanism. The output end of the drive motor is fixedly connected to the screw rod.

[0012] Preferably, a fixing plate is fixedly connected to each of the two opposite end faces of the mounting shells near the pedal body, and a transmission rod is rotatably connected between the two fixing plates. Evenly distributed rubber scrapers are fixedly connected to the outside of the transmission rod, and driven bevel gears are symmetrically fixedly connected to the outside of the transmission rod near the mounting shell.

[0014] Preferably, the buffer mechanism further includes an external threaded tube and a screw plug. The external threaded tube is symmetrically fixedly connected to the outer side of the horizontal tube near the center. The external threaded tube is connected to the inside of the horizontal tube.

[0017] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0018] 1. In this electric pedal with soft start and soft stop function, through the cooperation between the lifting component, the buffer mechanism, the pedal body and the electric telescopic rod, the electric telescopic rod can drive the pedal body to extend and retract, and at the same time drive the crossbar and the lever to rotate forward and reverse. When the crossbar is filled with water, the lever rotates in the water and generates resistance, which achieves a buffering effect. This solves the problem that the sudden start or stop of the telescopic action causes the drive components and connecting structures to bear large instantaneous stress for a long time.

[0019] 2. This electric pedal with soft start and soft stop function, through the cooperation of hidden components, a cleaning mechanism, a drive motor, a rubber scraper, a transmission bevel gear, and a screw, achieves the following when the pedal body needs to be retracted: the drive motor rotates, first moving the pedal body towards the mounting shell; simultaneously, the rubber scraper rotates to clean debris from the top of the pedal body; when the pedal body reaches its limit position towards the mounting shell, the electric telescopic rod drives the pedal body to retract, achieving the functions of hiding the pedal body and cleaning it. This effectively solves the problem that the surface of the pedal body is easily contaminated with mud, snow, sand, and other debris during use, and when these debris accumulates to a certain extent, it directly hinders the normal retraction of the electric pedal, leading to damage to the electric pedal.

[0033] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0034] Due to the power output characteristics of the drive components, electric pedals often lack a smooth transition during start-up and stop, exhibiting sudden initiation or abrupt cessation of the extension / retraction action. This causes the drive components and connecting structures to endure significant instantaneous stress over a long period, easily leading to wear, deformation, or even failure of components, severely shortening the lifespan of the electric pedals. Furthermore, as an exposed component outside the vehicle, the surface of the electric pedal is easily contaminated with mud, snow, sand, and other debris during use. When these debris accumulates to a certain extent, it directly hinders the normal retraction action of the electric pedal. At best, this prevents the pedal from fully retracting to its concealed position, affecting the vehicle's appearance and driving safety. At worst, it can cause drive components to jam or overload, leading to serious malfunctions such as motor burnout and gear breakage, significantly increasing the equipment's maintenance costs and failure rate.

[0035] Therefore, the present invention provides an electric pedal with soft start and soft stop function, see [link to relevant documentation]. Figures 1-11As shown, it includes two fixed shells 1, with a pedal body 4 on one side of each fixed shell 1. Lifting components 2 are provided on the inner sides of both fixed shells 1, and a buffer mechanism 3 is provided between the two fixed shells 1. The lifting components 2 and the buffer mechanism 3 are used in conjunction with the pedal body 4. A hidden component 6 is provided at the end away from the two fixed shells 1. The hidden component 6 includes a cleaning mechanism 7 for cleaning the pedal body 4 and an anti-slip mechanism 5 for improving the use effect of the pedal body 4.

[0036] See Figures 1-9 As shown, the lifting assembly 2 includes a support shaft 201, a support gear 202, a swing arm 203, a rack 204, an electric telescopic rod 205, and a support plate 206. The center of the inner side of the fixed housing 1 and the position near the pedal body 4 are both rotatably connected to the support shaft 201 via bearings. Swing arms 203 are symmetrically fixedly connected to the outer sides of the two support shafts 201 on the same fixed housing 1. The support gear 202 is fixedly connected to the outer side of the support shaft 201 near the center of the fixed housing 1. A rack 204 is slidably connected to the top of the inner cavity of the fixed housing 1, and the rack 204 is connected to the support gear 202. The two fixed housings 1 are engaged. An electric telescopic rod 205 is installed on the side of the fixed housing 1 away from the pedal body 4. The telescopic end of the electric telescopic rod 205 passes through the fixed housing 1 and is movably connected to it. The telescopic end of the electric telescopic rod 205 is fixedly connected to the rack 204. Four swing arms 203 within the same fixed housing 1 are movably connected to support plates 206 near the pedal body 4. The bottom of the pedal body 4 is fixedly connected to the tops of the two support plates 206. The buffer mechanism 3 includes a horizontal plate 301, a lug 302, a horizontal tube 303, a horizontal rod 304, and a lever 305. Between the two fixed housings 1... A horizontal plate 301 is fixedly connected at four points away from the pedal body. A lug 302 is symmetrically fixedly connected to the bottom of the horizontal plate 301. A horizontal tube 303 is fixedly connected between the two lugs 302. A horizontal rod 304 is installed inside the horizontal tube 303. Both ends of the horizontal rod 304 pass through the lugs 302 and are movably connected to them. Evenly distributed paddle plates 305 are fixedly connected to the outside of the horizontal rod 304. The buffer mechanism 3 also includes a driven gear 306 and a transmission sector gear 307. The driven gear 306 is fixedly connected to both ends of the horizontal rod 304. Supports are located near the center inside the two fixed housings 1. The end of the support shaft 201 away from the fixed housing 1 is fixedly connected to the transmission sector gear 307 through the inner ring of the bearing. The transmission sector gear 307 meshes with the driven gear 306. The buffer mechanism 3 also includes an external threaded tube 308 and a screw plug 309. The external threaded tube 308 is symmetrically fixedly connected to the outer side of the horizontal tube 303 near the center. The external threaded tube 308 is connected to the inside of the horizontal tube 303. The top of the external threaded tube 308 located on the upper side passes through the horizontal plate 301 and extends to the upper side of the horizontal plate 301. The ends of the two external threaded tubes 308 away from the horizontal tube 303 are each equipped with a screw plug 309.

[0037] When in operation, if it is necessary to extend the pedal body 4, by opening the car door, the control system will first activate the two electric telescopic rods 205 to pull the rack 204. The rack 204 drives the support gear 202 to rotate forward, and the support gear 202 drives the support shaft 201 to rotate forward, causing the swing arm 203 to swing outward in the direction of the car, so that the pedal body 4 can extend outward. When the support shaft 201 rotates forward, it will also drive the transmission sector gear 307 to swing downward. The transmission sector gear 307 drives the driven gear 306 to rotate, so that the crossbar 304 drives the lever 305 to rotate in the liquid. The resistance of the lever 305 rotating in the liquid can buffer the mechanical action of the pedal body 4 when it extends.

[0038] See Figures 3-10 As shown, the hidden component 6 includes a mounting shell 601, a movable block 602, a screw hole 603, a screw rod 604, and a drive motor 605. The ends of the two fixed shells 1 furthest from the horizontal plate 301 are each provided with a mounting shell 601. The side of the mounting shell 601 opposite to the fixed shell 1 is open. The movable block 602 is symmetrically arranged inside the mounting shell 601. A screw hole 603 is opened on one side of the movable block 602. A screw rod 604 is installed between two adjacent screw holes 603. Both ends of the screw rod 604 penetrate the mounting shell 601 and are movably connected to it. The drive motor 605 is installed on the side of the mounting shell 601 furthest from the anti-slip mechanism 5. The output end of the drive motor 605 is fixedly connected to the screw rod 604. The ends of the two mounting shells 601 furthest from each other are fixedly connected to the pedal body 4. A fixed plate 701 is rotatably connected between two fixed plates 701. Evenly distributed rubber scrapers 703 are fixedly connected to the outer side of the transmission rod 702. A driven bevel gear 704 is symmetrically fixedly connected to the outer side of the transmission rod 702 near the mounting housing 601. A transmission bevel gear 705 is fixedly connected to the end of the screw 604 away from the drive motor 605. The transmission bevel gear 705 meshes with the driven bevel gear 704. The anti-slip mechanism 5 includes a groove 501, a heating wire 502, and sealing covers 503 and 504. A groove 501 is provided on the top of the pedal body 4. A heating wire 502 is installed at the bottom of the inner cavity of the groove 501. A sealing cover 503 is installed on the top of the groove 501. Mounting ear plates 8 are fixedly connected to the bottom of the two mounting housings 601 on opposite sides.

[0039] During operation, the two drive motors 605 are started to drive the screws 604 to rotate forward, causing the two movable blocks 602 to move outwards from the car. Simultaneously, the movable blocks 602 drive the fixed shell 1 and the pedal body 4 to move outwards as a whole. During the displacement process, the pedal body 4 will pass through the rubber scraper 703, which will clean the top of the pedal body 4. In addition, when the two screws 604 rotate, they will also drive the transmission bevel gear 705 to rotate. The transmission bevel gear 705 will drive the driven bevel gear 704, the transmission rod 702 and the rubber scraper 703 to rotate. In this way, when the pedal body 4 passes through the rubber scraper 703, its top is cleaned better, effectively improving the cleaning effect.

[0040] The purpose of extending the pedal body 4 is achieved when the two fixed housings 1 and the pedal body 4 extend to their extreme positions outwards from the car. After the pedal body 4 is used and the car door is closed, the control system will prioritize controlling the drive motor 605 to reverse, causing the movable block 602 and the fixed housing 1 to move inwards from the car. This allows the pedal body 4 to pass under the rubber scraper 703 again. Because the screw 604 is reversed, the rubber scraper 703 follows the screw 604 to reverse and clean the top of the pedal body 4. When the pedal body 4 moves to its extreme position towards the fixed housing 1, the drive motor 605 is turned off, and the electric telescopic rod 205 is activated. The movement of the rack 204 towards the pedal body 4 causes the support gear 202 to reverse, resulting in the swing arm 203 swinging inward toward the inside of the car. This causes the support plate 206 and the pedal body 4 to retract as a whole. The above operation achieves the purpose of retracting and hiding the pedal body 4. In addition, when the swing arm 203 swings inward toward the inside of the car, the support shaft 201 reverses, causing the transmission sector gear 307 to swing upward. The transmission sector gear 307 then drives the driven gear 306 and the crossbar 304 to reverse, causing the paddle 305 to rotate in the liquid. This also achieves the buffering effect through the resistance generated by the rotation in the liquid.

[0041] When necessary, the heating wire 502 can be activated to heat the top of the pedal body 4. In rainy or snowy weather, this can melt the snow on the pedal body 4 and prevent the top of the pedal body 4 from freezing, thus preventing slippage during use and improving safety.

[0042] In summary, this effectively solves the problem that electric pedals often lack a smooth transition during start-up and stop due to the power output characteristics of the drive components. This manifests as sudden start-up or abrupt stop of the extension / retraction action, causing the drive components and connecting structures to be subjected to large instantaneous stress for a long time. This easily leads to wear, deformation, or even failure of components, severely shortening the service life of the electric pedals. Furthermore, as an exposed component outside the vehicle, the surface of the electric pedal is easily contaminated with mud, snow, sand, and other debris during use. When these debris accumulates to a certain extent, it directly hinders the normal retraction action of the electric pedal. At best, it prevents the pedal from fully retracting to the hidden position, affecting the vehicle's appearance and driving safety. At worst, it may cause the drive components to jam or overload, leading to serious malfunctions such as motor burnout and gear breakage, significantly increasing the maintenance cost and failure rate of the equipment.

[0043] Working Principle: In use, this technical solution first installs the two fixed housings 1 and the pedal body 4 in the corresponding positions on the car using two mounting ears 8. After testing, the pedal body 4 extends when the car door is opened and retracts and hides when the door is closed. Once testing is complete, the upper screw plug 309 is removed, and the horizontal pipe 303 is filled with liquid through the external threaded tube 308. Then, the screw plug 309 is installed on the external threaded tube 308 to prevent liquid leakage. Next, during use, if it is necessary to extend the pedal body 4, opening the car door will activate two electric... The telescopic rod 205 pulls the rack 204, which in turn drives the support gear 202 to rotate forward. Simultaneously, the support gear 202 drives the support shaft 201 to rotate forward, causing the swing arm 203 to swing outward towards the outside of the car, thus extending the pedal body 4 outward. When the support shaft 201 rotates forward, it also drives the transmission sector gear 307 to swing downward. The transmission sector gear 307 drives the driven gear 306 to rotate, causing the crossbar 304 to drive the lever 305 to rotate in the liquid. The resistance of the lever 305 rotating in the liquid buffers the mechanical action of the pedal body 4 during extension.

[0044] When the swing arm 203 swings upward to its limit position, the two drive motors 605 are simultaneously activated to drive the screw 604 to rotate forward, causing the two movable blocks 602 to move outward from the car. Simultaneously, the movable blocks 602 drive the fixed shell 1 and the pedal body 4 to move outward as a whole. During the displacement process, the pedal body 4 will pass through the rubber scraper 703, which will clean the top of the pedal body 4. In addition, when the two screws 604 rotate, they will also drive the transmission bevel gear 705 to rotate. The transmission bevel gear 705 will drive the driven bevel gear 704, the transmission rod 702 and the rubber scraper 703 to rotate. In this way, when the pedal body 4 passes through the rubber scraper 703, its top is cleaned better, effectively improving the cleaning effect.

[0045] The purpose of extending the pedal body 4 is achieved when the two fixed housings 1 and the pedal body 4 extend to their extreme positions outwards from the car. After the pedal body 4 is used and the car door is closed, the control system will prioritize controlling the drive motor 605 to reverse, causing the movable block 602 and the fixed housing 1 to move inwards from the car. This allows the pedal body 4 to pass under the rubber scraper 703 again. Because the screw 604 is reversed, the rubber scraper 703 follows the screw 604 to reverse and clean the top of the pedal body 4. When the pedal body 4 moves to its extreme position towards the fixed housing 1, the drive motor 605 is turned off, and the electric telescopic rod 205 is activated. The movement of the rack 204 towards the pedal body 4 causes the support gear 202 to reverse, resulting in the swing arm 203 swinging inward toward the inside of the car. This causes the support plate 206 and the pedal body 4 to retract as a whole. The above operation achieves the purpose of retracting and hiding the pedal body 4. In addition, when the swing arm 203 swings inward toward the inside of the car, the support shaft 201 reverses, causing the transmission sector gear 307 to swing upward. The transmission sector gear 307 then drives the driven gear 306 and the crossbar 304 to reverse, causing the paddle 305 to rotate in the liquid. This also achieves the buffering effect through the resistance generated by the rotation in the liquid.
