Description

Technical Field

[0001] This invention belongs to the technical field of electric vehicle pedals, and in particular relates to an active linkage device, an electric pedal, and a vehicle. Background Technology

[0002] Electric pedals use a motor to drive a linkage to automatically extend and retract the pedals, providing convenient foot support for passengers getting on and off the vehicle.

[0003] In the field of new energy vehicles, power batteries are typically designed to be larger in size to improve the vehicle's driving range. However, when a larger power battery is placed in the chassis, its installation space can easily overlap with the retracted electric pedal in the vehicle's height direction, thereby obstructing the original traditional lifting support points on the vehicle's longitudinal beams. As a result, the current lifting support points are placed on the electric pedal's linkage.

[0004] However, due to inherent position control accuracy deviations in the electric pedal motor when controlling the pedal retract to its limit position, a gap may exist between the retracted linkage and the mounting base, causing the linkage to be in a "suspended" state. When the lift is used to raise the vehicle, the enormous weight of the entire vehicle will act on the suspended linkage, causing it to bend like a lever. This not only easily leads to bending or even breakage of the linkage, but the abnormal torque will also be transmitted in reverse to the motor, disrupting the meshing of the precision gears inside the motor. Over time, this may cause abnormal noises during the operation of the electric pedal and severely damage its durability. Summary of the Invention

[0005] In view of this, it is necessary to provide an active linkage device, an electric pedal, and a vehicle that, by controlling the manual decoupling between the drive rod and the rotating shaft on the rotary drive component, allows the drive rod to disengage from the rotating shaft when lifted by an external force, preventing the drive rod from driving the rotating shaft in the opposite direction and thus avoiding any impact on the rotary drive component.

[0006] To solve the above-mentioned technical problems, this application provides the following technical solution:

[0007] An active linkage device for use in an electric pedal of a vehicle, the active linkage device comprising:

[0008] Linkage assembly, including drive rod;

[0009] A rotary drive component having a rotating shaft passing through the drive rod;

[0010] A transmission block is movably disposed on the drive rod along a first direction for coupling or decoupling the rotating shaft and the drive rod. The first direction is set at an angle to the axis of the rotating shaft.

[0011] An adjusting rod is movably mounted on the drive rod and connected to the transmission block, and the adjusting rod has an adjusting head located outside the drive rod;

[0012] When the adjusting head is subjected to a first force, the adjusting head can drive the transmission block to extend in the first direction, so as to decouple the rotating shaft from the driving rod; when the adjusting head is subjected to a second force, the adjusting head can drive the extended transmission block to retract in the first direction, so as to couple the rotating shaft with the driving rod.

[0013] Understandably, by extending or retracting the transmission block in the first direction through the force applied to the adjusting head on the adjusting rod, manual decoupling between the rotating shaft and the drive rod can be achieved. This design, on the one hand, allows the drive rod to rotate freely relative to the rotating shaft, fundamentally eliminating the cantilever stress state and preventing the drive rod from breaking due to excessive bending torque during lifting; on the other hand, it cuts off the force transmission path between the drive rod and the rotary drive component, preventing the drive rod from creating reverse drive on the rotary drive component, thus protecting the internal structure of the rotary drive component and preventing abnormal noises and reduced durability caused by abnormal torque. Furthermore, the decoupling design between the linkage assembly and the rotary drive component allows maintenance personnel to independently inspect both, quickly locating the fault point, improving the fault diagnosis efficiency of the active linkage device, and reducing disassembly and repair costs.

[0014] In one embodiment, the adjusting rod is rotatably mounted on the drive rod;

[0015] Furthermore, the end of the adjusting rod away from the adjusting head passes through the transmission block and is threadedly connected to the transmission block.

[0016] It is understandable that by utilizing the threaded connection between the adjusting rod and the transmission block, the transmission block can be extended or retracted relative to the drive rod simply by driving the adjusting rod to rotate through the adjusting head. This facilitates the decoupling and coupling of the rotating shaft and the drive rod.

[0017] In one embodiment, the active linkage device further includes a limiting cover, which is disposed on the adjusting head and connected and fixed to the drive rod, for positioning the adjusting rod at its upper limit in the first direction relative to the drive rod.

[0018] Understandably, by limiting the adjusting rod with the limiting cover, it can be ensured that during the rotation of the adjusting head under positive force, the adjusting rod can only rotate in place without generating axial displacement, so as to drive the transmission block to move in extension and retraction along the axis of the adjusting rod. This ensures the stability of coupling or decoupling the rotating shaft and the driving rod.

[0019] In one embodiment, the limiting cover has a pressing portion, and the limiting cover can press and limit the adjusting head through the pressing portion;

[0020] The pressure cap has a through hole for an external tool to pass through and cooperate with the adjustment head to drive the adjustment rod.

[0021] In one embodiment, a limiting piece is connected to the adjusting rod at the portion through which it passes the transmission block. The limiting piece is capable of abutting against the extended transmission block, thereby positioning the transmission block at its upper limit in the first direction relative to the adjusting rod.

[0022] When the limiting piece abuts against the transmission block, the rotating shaft and the driving rod are decoupled.

[0023] Understandably, by using an upper limit plate on the adjusting rod to abut against the transmission block, the maximum stroke of the transmission block when it extends is limited to prevent it from completely disengaging from the adjusting rod. This design not only eliminates the need for operators to consciously control the number of rotations of the adjusting rod during manual decoupling, thus improving operational convenience, but also provides structural support for subsequently retracting the transmission block by rotating the adjusting rod in the opposite direction. This ensures smooth and reliable operation throughout the entire decoupling and coupling process.

[0024] In one embodiment, the transmission block has a countersunk hole, and the adjusting rod passes through the countersunk hole;

[0025] The limiting piece is at least partially housed within the countersunk hole and is able to abut against and limit the bottom of the countersunk hole.

[0026] It is understandable that by housing the limiting plate in the countersunk hole of the transmission block and using the abutting fit between the bottom of the countersunk hole and the limiting plate, the extension stroke of the transmission block is limited. This integrates the structure that limits the extension stroke of the transmission block into the interior of the transmission block, achieving a compact design for the assembly of the adjusting rod and the transmission block, thus meeting the usage requirements for installation inside the drive rod.

[0027] In one embodiment, the drive rod is provided with a receiving groove, and the transmission block is movably disposed in the receiving groove along the first direction;

[0028] The groove wall of the receiving groove has a raised rib, which extends along the first direction and can abut against the side wall of the transmission block to circumferentially limit the transmission block.

[0029] Understandably, by using the protruding ribs on the drive rod to abut against and limit the transmission block, circumferential constraints can be achieved on the transmission block. This ensures that the transmission block moves linearly along the axis of the adjusting rod, preventing the transmission block from skewing or misaligning during extension and retraction. This improves the accuracy and reliability of the coupling and decoupling operations between the rotating shaft and the drive rod.

[0030] In one embodiment, the number of the ribs is configured to be multiple, and the multiple ribs are arranged circumferentially on different sidewalls of the receiving groove of the transmission block.

[0031] It is understandable that by setting multiple ribs on different side walls of the receiving groove on the drive rod, the transmission block can be constrained at multiple angles and in different directions, which improves the uniformity of the circumferential limiting force on the transmission block during the extension and retraction process, avoids the transmission block generating additional deflection torque on the adjusting rod, and ensures that the adjusting rod only needs to bear a single rotational force, which is beneficial to extending the service life of the adjusting rod.

[0032] This application also provides an electric pedal, including the aforementioned active linkage device.

[0033] This application also provides a vehicle including the above-described active linkage device;

[0034] Alternatively, it may include the electric pedals described above.

[0035] Due to the application of the above technical solution, the present invention has the following advantages compared with the prior art:

[0036] The active linkage device, electric pedal, and vehicle claimed in this application achieve manual decoupling between the rotating shaft and the drive rod by extending or retracting the transmission block in a first direction through the force of the adjusting head on the adjusting rod. This design, on the one hand, allows the drive rod to rotate freely relative to the rotating shaft, fundamentally eliminating the cantilever stress state and preventing the drive rod from breaking due to excessive bending torque during lifting; on the other hand, it cuts off the force transmission path between the drive rod and the rotary drive component, preventing the drive rod from generating reverse drive on the rotary drive component, thereby protecting the internal structure of the rotary drive component and preventing abnormal noise and reduced durability caused by abnormal torque. Furthermore, the decoupling design between the linkage assembly and the rotary drive component allows maintenance personnel to independently inspect both, quickly locating the fault point, improving the fault diagnosis efficiency of the active linkage device, and reducing disassembly and repair costs.

Detailed Implementation

[0046] 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 a part of the embodiments of the present invention, and not all of them. 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.

[0047] It should be noted that when a component is said to be "located on" another component, it can be directly located on the other component or may have an intervening component. When a component is considered to be "located on" another component, it can be directly located on the other component or may have an intervening component. When a component is considered to be "fixed to" another component, it can be directly fixed to the other component or may have an intervening component.

[0048] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0049] like Figure 1 , Figure 3 As shown, the active linkage device 100 for which protection is sought in this application belongs to the linkage structure with power input in the electric pedal 1000 of a vehicle, and is used to control the automatic extension or retraction of the pedal 200.

[0050] like Figures 1 to 7As shown, the active linkage device 100 provided in this application includes a linkage assembly 10, a rotary drive member 20, a transmission block 30, and an adjusting rod 40. The linkage assembly 10 includes a drive rod 11. The rotary drive member 20 has a rotating shaft 21, which passes through the drive rod 11. The transmission block 30 is movably disposed on the drive rod 11 along a first direction P, for coupling or decoupling the rotating shaft 21 and the drive rod 11. The first direction P is angularly disposed with respect to the axis of the rotating shaft 21. The adjusting rod 40 is movably mounted on the drive rod 11 and is connected to the transmission block 30. The adjusting rod 40 has an adjusting head 41 located outside the drive rod 11. When the adjusting head 41 is subjected to a positive force, the adjusting head 41 can drive the transmission block 30 to extend in the first direction P, thereby decoupling the rotating shaft 21 from the drive rod 11. When the adjusting head 41 is subjected to a negative force, the adjusting head 41 can drive the extended transmission block 30 to retract in the first direction P, thereby coupling the rotating shaft 21 with the drive rod 11. In other words, the active linkage device 100 of this application can be manually decoupled from the rotating shaft 21 and the drive rod 11. This design, on the one hand, allows the drive rod 11 to rotate freely relative to the rotating shaft 21, fundamentally eliminating the cantilever stress state and preventing the drive rod 11 from breaking due to excessive bending torque during lifting; on the other hand, it cuts off the force transmission path between the drive rod 11 and the rotary drive component 20, preventing the drive rod 11 from creating reverse drive on the rotary drive component 20, thereby protecting the internal structure of the rotary drive component 20 and preventing abnormal noise and reduced durability caused by abnormal torque. Furthermore, the decoupling design between the linkage assembly 10 and the rotary drive component 20 allows maintenance personnel to independently inspect both, quickly locating the fault point, which improves the fault diagnosis efficiency of the active linkage device 100 and reduces disassembly and repair costs.

[0051] Here, the decoupling between the rotating shaft 21 and the drive rod 11 specifically means that the force transmission path between the rotating shaft 21 and the drive rod 11 is cut off, and the drive rod 11 cannot drive the rotating shaft 21 in the reverse direction. Conversely, the coupling between the rotating shaft 21 and the drive rod 11 means that a force transmission path is established between them, and the rotating shaft 21 can drive the drive rod 11 to rotate via the transmission block 30. It should be noted that the first force can be a forward rotational force or a thrust force about the first direction P, and the second force can be a reverse rotational force or a pulling force about the first direction P.

[0052] like Figure 2 , Figure 4As shown, in one embodiment, the linkage assembly 10 further includes a mounting base 12, a driven rod 13, and a pedal bracket 14. One end of the drive rod 11 away from the rotating shaft 21 is rotatably connected to one end of the pedal bracket 14. One end of the driven rod 13 is rotatably connected to the mounting base 12, and the other end is rotatably connected to the middle of the pedal bracket 14. The other end of the pedal bracket 14 is fixedly connected to the pedal 200. In this way, the drive rod 11, driven rod 13, mounting base 12, and pedal bracket 14 in the linkage assembly 10 can form a four-bar linkage structure, so that when the drive rod 11 is driven by the rotating shaft 21, it can drive the pedal bracket 14 and the pedal 200 to perform telescopic movements through the four-bar linkage structure.

[0053] Here, the rotary drive component 20 is fixedly connected to the mounting base 12. Specifically, the body 22 of the rotary drive component 20 can be disposed on the outside of the mounting base 12 and connected and fixed to the mounting base 12. It can be understood that the rotary drive component 20 can be configured as a servo motor, stepper motor, etc., preferably a servo motor with an integrated speed change module.

[0054] The rotating drive component 20 has a rotating shaft 21 that passes through the drive rod 11 and is rotatably connected to the mounting base 12. The section of the rotating shaft 21 located within the drive rod 11 has a flat surface 211. When the rotating shaft 21 rotates, the flat surface 211 pushes against the transmission block 30. By utilizing the abutment and limiting relationship between the transmission block 30 and the drive rod 11, the rotational motion of the rotating shaft 21 is converted into a drive for the drive rod 11 to rotate on the mounting base 12, thereby controlling the extension or retraction of the pedal 200.

[0055] like Figure 5 , Figure 7 As shown, in one embodiment, the transmission block 30 is configured in a wedge shape, such that the transmission block 30 can use its wedge-shaped surface 31 to abut and limit the drive rod 11, thereby achieving the abutment and limitation between the transmission block 30 and the drive rod 11.

[0056] like Figure 4 , Figure 5 As shown, in one embodiment, the adjusting rod 40 is rotatably mounted on the drive rod 11; and the adjusting rod 40 passes through the transmission block 30 along the first direction P and is threadedly connected to the transmission block 30. This embodiment utilizes the threaded engagement structure between the adjusting rod 40 and the transmission block 30, allowing the transmission block 30 to extend or retract relative to the drive rod 11 simply by rotating the adjusting rod 40 via the adjusting head 41. This facilitates the decoupling and coupling operations between the rotating shaft 21 and the drive rod 11. Of course, this is not the only possibility. Those skilled in the art can also assemble the transmission block 30 onto the adjusting rod 40 in an axially limiting manner, using the adjusting rod 40 to directly drive the extension and retraction of the transmission block 30 to control the decoupling and coupling operations between the rotating shaft 21 and the drive rod 11. This will not be elaborated upon here.

[0057] like Figure 2 , Figure 4 , Figure 5 and Figure 7 As shown, the active linkage device 100 also includes a limiting cover 50, which covers the adjusting head 41 and is connected and fixed to the drive rod 11. The limiting cover 50 is used to position the adjusting rod 40 at its upper limit in the first direction P relative to the drive rod 11, so that when the adjusting head 41 is rotated under force, the adjusting rod 40 can only rotate in place without axial displacement, thereby driving the transmission block 30 to extend and retract along the first direction P. This ensures the stability of coupling or decoupling operations between the rotating shaft 21 and the drive rod 11. It should be noted that the aforementioned "axial limitation of the adjusting rod 40 to the drive rod 11" specifically refers to the adjusting rod 40 being assembled and limited with the drive rod 11 in the extension and retraction direction of the transmission block 30.

[0058] The limiting cover 50 has a pressing part 51, and the limiting cover 50 can press the limiting adjustment head 41 through the pressing part 51 to restrict the limiting adjustment head 41 from moving away from the drive rod 11; at the same time, the limiting adjustment head 41 forms position interference with the drive rod 11 in the extension direction of the adjustment rod 40, and the two work together to achieve axial limiting of the adjustment rod 40 on the drive rod 11.

[0059] Here, the pressure cap 51 is formed by the portion of the limiting cover 50 protruding outward in a direction away from the drive rod 11; the limiting cover 50 is pressed and fixed to the drive rod 11 by two screws 501, the two screws 501 being located on the two outer sides of the pressure cap 51, so as to facilitate the assembly of the limiting cover 50 onto the drive rod 11.

[0060] Preferably, the pressure cap 51 has a through hole 511, which allows an external tool to pass through the pressure cap 51 and engage with the adjusting head 41 to drive the adjusting rod 40. This ensures that the pressure cap 51 maintains pressure on the adjusting head 41 without affecting the tightening operation. It is understood that the adjusting rod 40 can be a bolt, and its adjusting head 41 can be a bolt head. Users can easily tighten and adjust the adjusting rod 40 using a conventional screwdriver.

[0061] like Figures 4 to 7As shown, in one embodiment, a limiting piece 60 is connected to the adjusting rod 40 at the portion passing through the transmission block 30. The limiting piece 60 can abut against the extended transmission block 30, thereby keeping the transmission block 30 at its upper limit in the first direction P above the adjusting rod 40. Furthermore, when the limiting piece 60 abuts against the transmission block 30, the rotating shaft 21 and the drive rod 11 are decoupled. In other words, in this embodiment, the adjusting rod 40 can use the limiting piece 60 to abut against the transmission block 30 to limit the maximum stroke of the extended transmission block 30, preventing the transmission block 30 from completely detaching from the adjusting rod 40. This design not only eliminates the need for operators to manually control the number of rotations of the adjusting rod 40 during decoupling, improving operational convenience, but also provides structural support for subsequently retracting the transmission block 30 by rotating the adjusting rod 40 in the opposite direction, thus ensuring smooth and reliable operation throughout the decoupling and coupling process.

[0062] Here, the limiting piece 60 is configured as a snap ring, which can be attached to the adjusting rod 40 by snap-fit. Of course, it is not limited to this. For those skilled in the art, the limiting piece 60 can also be configured as a washer that is welded to the adjusting rod 40, which will not be elaborated here.

[0063] like Figure 4 , Figure 5 As shown, the transmission block 30 has a countersunk hole 32, and the end of the adjusting rod 40 away from the adjusting head 41 passes through the countersunk hole 32. The limiting piece 60 is at least partially housed within the countersunk hole 32 and can abut against the bottom 321 of the countersunk hole 32 for limiting its movement. This integrates the structure that limits the extension stroke of the transmission block 30 into the interior of the transmission block 30, achieving a compact design for the assembly of the adjusting rod 40 and the transmission block 30, thus meeting the requirements for installation inside the drive rod 11. Of course, this is not the only possibility. For those skilled in the art, the limiting piece 60 on the adjusting rod 40 can also be located outside the countersunk hole 32 on the transmission block 30 and housed within the drive rod 11, or even outside the drive rod 11. This will not be elaborated upon here.

[0064] Here, the transmission block 30 is also provided with a through hole 33 coaxially arranged with the countersunk hole 32, and the adjusting rod 40 is sequentially inserted into the through hole 33 and the countersunk hole 32 along its axial direction.

[0065] like Figure 6As shown, in one embodiment, the drive rod 11 is provided with a receiving groove 110, and the transmission block 30 is movably disposed in the receiving groove 110 along the first direction P; wherein, the groove wall of the receiving groove 110 has a protruding rib 111, the protruding rib 111 extends along the first direction P, and the protruding rib 111 can abut against the side wall of the transmission block 30 to circumferentially limit the transmission block 30, thereby achieving circumferential constraint on the transmission block 30. This can ensure that the transmission block 30 moves linearly along the axial direction of the adjusting rod 40, and avoid the transmission block 30 from being skewed or misaligned during the extension and retraction process, thereby improving the accuracy and reliability of the coupling and decoupling operation between the rotating shaft 21 and the drive rod 11.

[0066] Here, the aforementioned protruding rib 111 can abut against other sides of the transmission block 30, excluding the wedge-shaped surface 31, to achieve circumferential constraint on the transmission block 30 during its telescopic movement.

[0067] Preferably, the number of protruding ribs 111 is multiple, and the multiple protruding ribs 111 are arranged circumferentially on different side walls of the receiving groove 110, so that the drive rod 11 can form multi-angle and different orientation limiting constraints on the transmission block 30, improve the uniformity of the circumferential limiting force on the transmission block 30 during the extension and retraction process, avoid the transmission block 30 generating additional deflection torque on the adjusting rod 40, ensure that the adjusting rod 40 only needs to bear a single rotational force, and help extend the service life of the adjusting rod 40.

[0068] Here, the number of protruding ribs 111 is configured as two, and the two protruding ribs 111 are arranged on two symmetrical sides of the transmission block 30. Of course, it is not limited to this. For those skilled in the art, the number of protruding ribs 111 can also be configured as three, four, five, or even more, which will not be elaborated here.

[0069] In summary, this application allows for manual control of decoupling or coupling between the rotating shaft 21 and the drive rod 11 by using an external tool to turn the adjusting head 41 on the adjusting rod 40 and utilizing the threaded engagement between the adjusting rod 40 and the transmission block 30. When decoupling is required, turning the adjusting rod 40 in the forward direction drives the transmission block 30 to extend until it abuts against the bottom 321 of the countersunk hole 32. At this point, the wedge-shaped surface 31 on the transmission block 30 disengages from the flat surface 211 on the rotating shaft 21, thus completing the decoupling of the rotating shaft 21 and the drive rod 11. When recoupling is required, turning the adjusting rod 40 in the reverse direction retracts the transmission block 30 until the wedge-shaped surface 31 on the transmission block 30 re-fits the flat surface 211, thereby achieving coupling between the rotating shaft 21 and the drive rod 11.

[0070] This application also provides an electric pedal 1000, including the aforementioned active linkage device 100.

[0071] like Figure 1 , Figure 3As shown, the electric pedal 1000 also includes a pedal 200 and a driven linkage device 300. The driving linkage device 100 and the driven linkage device 300 are respectively connected and fixed to the pedal 200, and together they are used to drive the pedal 200 to extend or retract on the bottom of the vehicle body. It can be understood that the structure of the driven linkage device 300 is basically the same as that of the driving linkage device 100. The only difference is that the driven linkage device 300 lacks the rotary drive component 20 compared to the driving linkage device 100, which will not be elaborated upon here.

[0072] This application also provides a vehicle including the active linkage device 100 described above; or, including the electric pedal 1000 described above.

[0073] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0074] Those skilled in the art should recognize that the above embodiments are merely illustrative of the present invention and are not intended to limit the present invention. Any appropriate changes and variations made to the above embodiments within the essential spirit of the present invention fall within the scope of protection claimed by the present invention.
