Description

Technical Field

[0001] This utility model relates to the field of pedal device technology, and in particular to a linkage pedal device for intelligent braking energy recovery of electric vehicles. Background Technology

[0002] The intelligent braking energy recovery linkage pedal device for electric vehicles is a device that integrates acceleration and braking functions into a pedal design, combined with an electronic control system to achieve a single-pedal operation mode of "pressing down to accelerate, releasing to recover". Its core goal is to optimize energy recovery efficiency, reduce reliance on mechanical braking, and improve the driving experience.

[0003] Existing pedal devices typically use Hall effect sensors mounted on the pedal shaft to detect the shaft's rotation angle and transmit the data to the vehicle's control system via wires, where the system then recovers braking energy. However, existing Hall angle sensors are usually screwed onto the pedal, which is cumbersome to install. Furthermore, during use, the connection between the pedal shaft and the mounting bracket is exposed to the external environment, causing dust to accumulate inside the bearing at this connection point, accelerating bearing wear and resulting in poor performance. Therefore, we propose a linked pedal device for intelligent braking energy recovery in electric vehicles. Utility Model Content

[0004] The purpose of this utility model is to address the aforementioned shortcomings in the existing technology by proposing a linkage pedal device for intelligent braking energy recovery in electric vehicles.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a linkage pedal device for intelligent braking energy recovery of electric vehicles is designed, including a mounting frame, a groove on one side of the mounting frame, and a rotating shaft in the groove. The two ends of the rotating shaft are rotatably connected to the side wall of the mounting frame, and a pedal is connected to the side of the rotating shaft through a connecting rod.

[0006] Both ends of the rotating shaft extend outside the mounting bracket, and a fixed sleeve is coaxially mounted on one end of the rotating shaft. A magnetic ring is provided inside the fixed sleeve, and a pressure ring is provided at one end of the fixed sleeve. A threaded sleeve is installed on one side edge of the pressure ring. One end of the threaded sleeve is fitted onto the end of the fixed sleeve and is threadedly connected to the fixed sleeve. When the threaded sleeve is tightened, one side of the pressure ring abuts against the end of the magnetic ring.

[0007] Both sides of the mounting bracket are fitted with edging, the fixing sleeve is located inside the corresponding edging, and one end of each edging is connected to a cover plate. One of the cover plates has a Hall element on its side, one end of the Hall element extends into the magnetic ring, and the other end of the Hall element is fitted with a fixing seat, one end of the fixing seat rests against the side of the cover plate.

[0008] The side of the cover plate is coaxially connected with several connecting plates. The edge of the fixing seat is provided with several through slots. Each connecting plate is located in the corresponding through slot. Each connecting plate is equipped with a locking block on one side. Each through slot is provided with a locking groove on one side. One end of each locking block extends into the corresponding locking groove.

[0009] A dust cover is coaxially provided on the side of the rotating shaft. Both ends of the dust cover are fixed to the side wall of the mounting bracket by fixing rings. An opening is provided on one side of the dust cover, and one end of the connecting rod extends out of the opening. The inner wall of the opening is fixed to the side of the connecting rod.

[0010] Preferably, the outer surface of the magnetic ring is equipped with several limiting strips, and the inner side of the fixing sleeve is provided with several limiting grooves, with each limiting strip extending into the corresponding limiting groove.

[0011] Preferably, the connecting plates are made of elastic insulating material, and each connecting plate has a bending groove on one side of its bottom.

[0012] Preferably, one side of the card block is tilted.

[0013] Preferably, when the cover plate is fixed to the edge end, there is a gap between the fixing seat and the pressure ring.

[0014] Preferably, a connecting ring is installed at the end of the rotating shaft away from the fixed base, and a torsion spring is fitted at the end of the rotating shaft close to the connecting ring. One end of the torsion spring is fixed to the side of the connecting ring, and the other end of the torsion spring is fixed to the side of the mounting bracket.

[0015] Preferably, the dust cover is made of a flexible, stretchable material, and the sides of the dust cover have several creases.

[0016] The design scheme proposed in this utility model has the following beneficial effects in application:

[0017] 1. The threaded sleeve allows the pressure ring to fix the magnetic ring inside the fixed sleeve. Then, the elasticity of the connecting plate allows the locking block to extend into the locking groove to fix the fixing seat, thereby fixing the Hall element to the cover plate. This completes the fixing of the Hall element and the magnetic ring, making installation convenient.

[0018] 2. By using the cover plate and the surrounding edge, both ends of the rotating shaft can be covered, and the dust cover can cover the connection between the rotating shaft and the mounting bracket, thus preventing external dust from seeping into the connection between the rotating shaft and the mounting bracket during use and improving the performance.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0028] Reference Figures 1-7 A linkage pedal device for intelligent braking energy recovery of electric vehicles includes a mounting frame 1. A groove is provided on one side of the mounting frame 1, and a rotating shaft 10 is provided in the groove. The two ends of the rotating shaft 10 are rotatably connected to the side wall of the mounting frame 1. (Rotatable connection means that the two ends of the rotating shaft 10 are connected to the side wall of the mounting frame 1 through bearings.) The side of the rotating shaft 10 is connected to a pedal 9 through a connecting rod 8. The operator can drive the rotating shaft 10 to rotate by stepping on the pedal 9.

[0029] like Figure 1 and Figure 5As shown, both ends of the rotating shaft 10 extend outside the mounting bracket 1, and a fixing sleeve 18 is coaxially mounted on one end of the rotating shaft 10. A magnetic ring 16 is provided inside the fixing sleeve 18, and a pressure ring 25 is provided at one end of the fixing sleeve 18. A threaded sleeve 5 is installed on one side edge of the pressure ring 25. One end of the threaded sleeve 5 is fitted onto the end of the fixing sleeve 18 and is threadedly connected to the fixing sleeve 18. When the threaded sleeve 5 is tightened, one side of the pressure ring 25 abuts against the end of the magnetic ring 16. In actual use, by tightening the threaded sleeve 5, the magnetic ring 16 can be fixed inside the fixing sleeve 18 under the pressure ring 25, thereby fixing the magnetic ring 16 and the rotating shaft 10 together. In this way, when the rotating shaft 10 rotates, the magnetic ring 16 will rotate synchronously.

[0030] It should be noted that, as Figure 5 As shown, a number of limiting strips 17 are installed on the outer surface of the magnetic ring 16, and a number of limiting grooves 19 are opened on the inner side of the fixing sleeve 18. Each limiting strip 17 extends into the corresponding limiting groove 19. Through the cooperation of the limiting groove 19 and the limiting strip 17, the magnetic ring 16 and the fixing sleeve 18 can be limited, so that the magnetic ring 16 can rotate synchronously with the rotation of the fixing sleeve 18.

[0031] like Figure 2 and Figure 3 As shown, both sides of the mounting bracket 1 are equipped with a perimeter 2, and the fixing sleeve 18 is located inside the corresponding perimeter 2. One end of the perimeter 2 is connected to a cover plate 4. One of the cover plates 4 has a Hall element 14 on its side. One end of the Hall element 14 extends into the magnetic ring 16, and the other end of the Hall element 14 is equipped with a fixing seat 12. One end of the fixing seat 12 abuts against the side of the cover plate 4. The Hall element 14 is connected to the vehicle control system through a wire. In actual use, the rotating shaft 10 drives the magnetic ring 16 to rotate, which changes the direction of the magnetic field and thus changes the current generated by the Hall element 14. At this time, the rotation angle of the rotating shaft 10 can be detected. The Hall element 14 will transmit the current signal to the vehicle control system through the wire, and the control system controls the recovery of energy.

[0032] like Figure 3 and Figure 4 As shown, several connecting plates 15 are coaxially connected to the side of the cover plate 4. Several through slots 13 are opened on the edge of the fixing seat 12. Each connecting plate 15 is located in the corresponding through slot 13. A locking block 24 is installed on one side of each connecting plate 15. A slot 3 is opened on one side of each through slot 13. One end of each locking block 24 extends into the corresponding slot 3. In actual use, the fixing seat 12 can be fixed on the cover plate 4 by the cooperation of the locking block 24 and the slot 3. The fixing is convenient and the edge can be disassembled.

[0033] It should be noted that, as Figure 4As shown, the connecting plate 15 is made of elastic insulating material, and a bending groove 23 is provided on one side of the bottom of each connecting plate 15. One side of the locking block 24 is inclined. Under the action of the inclined surface of the locking block 24, when the worker moves the fixing seat 12 between the connecting plates 15, the edge of the fixing seat 12 will press against the inclined surface of the locking block 24, so that the end of the connecting plate 15 bends along the bending groove 23. In this way, the connecting plate 15 will not jam the fixing seat 12, making the connection convenient.

[0034] like Figure 1 , Figure 6 and Figure 7 As shown, a dust cover 7 is coaxially provided on the side of the rotating shaft 10. Both ends of the dust cover 7 are fixed to the side wall of the mounting bracket 1 by fixing rings 6. An opening 22 is provided on one side of the dust cover 7. One end of the connecting rod 8 extends out of the opening 22, and the inner wall of the opening 22 is fixed to the side of the connecting rod 8. The dust cover 7 can cover the side of the rotating shaft 10. In this way, during use, external dust will not adhere to the connection between the rotating shaft 10 and the mounting bracket 1, thereby not increasing the bearing wear at the connection between the rotating shaft 10 and the mounting bracket 1, and improving the performance.

[0035] It should be noted that, as Figure 6 and Figure 7 As shown, the dust cover 7 is made of flexible and stretchable material, and the side of the dust cover 7 has several creases 21. In this way, the dust cover 7 can deform with the rotation of the connecting rod 8, and the rotation of the connecting rod 8 will not cause the side of the rotating shaft 10 to be exposed to the external environment, thus improving the performance.

[0036] Specifically, during installation, the operator aligns the through groove 13 on the edge of the fixing seat 12 with the connecting plate 15, then moves the fixing seat 12 toward the connecting plate 15. One end of the connecting plate 15 moves into the through groove 13. Simultaneously, the bottom edge of the fixing seat 12 contacts the inclined surface of the locking block 24, pressing the locking block 24. The locking block 24 causes the connecting plate 15 to tilt outward along the bending groove 23, so that one end of the fixing seat 12 abuts against the side of the cover plate 4. At this time, the locking block 24 and... With the slots 3 aligned, the connecting plate 15, under its own elasticity, will move the locking block 24, causing one end of the locking block 24 to move into the slot 3, fixing the fixing seat 12, and thus fixing the Hall element 14. Then, the operator inserts the magnetic ring 16 into the fixing sleeve 18, causing the limiting strip 17 on the outer surface of the magnetic ring 16 to move into the corresponding limiting groove 19, fixing the magnetic ring 16. Afterwards, the operator tightens the threaded sleeve 5, causing the pressure ring 25 to press tightly against the end of the magnetic ring 16, thus fixing the magnetic ring 16. The magnetic ring 16 is fixed inside the fixing sleeve 18. Then, the operator fixes the cover plate 4 to the edge 2. At this time, one end of the Hall element 14 extends into the magnetic ring 16, and the installation is completed. The installation is convenient. At the same time, the cooperation between the cover plate 4 and the edge 2 can cover both ends of the rotating shaft 10, providing dust protection for both ends of the rotating shaft 10. When the operator steps on the pedal 9, the pedal 9 will drive the rotating shaft 10 to rotate through the connecting rod 8. The rotating shaft 10 will drive the magnetic ring 16 to rotate through the fixing sleeve 18, so that the Hall element 14 can sense different currents and transmit the current to the vehicle control system through the wire. The control system controls the energy recovery when the vehicle brakes. At the same time, during the stepping process, the connecting rod 8 will squeeze and pull the dust cover 7, so that the dust cover 7 will expand and contract under its own elasticity and the action of the crease 21, and always cover the connection between the rotating shaft 10 and the mounting bracket 1, preventing external dust from entering the connection between the rotating shaft 10 and the mounting bracket 1, thus improving the dustproof effect.

[0037] Furthermore, when the cover plate 4 is fixed to the end of the perimeter 2, there is a gap between the fixing seat 12 and the pressure ring 25. This way, when the pressure ring 25 rotates with the rotating shaft 10, it will not rub against the fixing seat 12, thus preventing the Hall element 14 from deflecting during use and improving the performance.

[0038] Furthermore, such as Figure 2 and Figure 5 As shown, a connecting ring 11 is installed at the end of the rotating shaft 10 away from the fixed seat 12, and a torsion spring 20 is sleeved at the end of the rotating shaft 10 close to the connecting ring 11. One end of the torsion spring 20 is fixed to the side of the connecting ring 11, and the other end of the torsion spring 20 is fixed to the side of the mounting bracket 1. Through the torque of the torsion spring 20, when the user releases the pedal 9, the torque of the torsion spring 20 will drive the connecting rod 8 to rotate, so that the connecting rod 8 returns to its original position.

[0039] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
