Description

Technical Field

[0001] This invention relates to the field of automotive pedal technology, specifically to a secondary telescopic electric automotive pedal. Background Technology

[0002] The retractable electric pedal is an electric mechanism designed to facilitate the entry and exit of drivers and passengers. This structure is installed on the chassis or side skirts of the vehicle and can extend or retract as the driver or passengers open or close the door.

[0003] When using electric pedals in electric vehicles, traditional telescopic pedals are usually folded down under the chassis to prevent them from protruding during retraction. Since the folded pedals have a certain thickness, retracting them to the bottom of the chassis can take up chassis space and increase chassis thickness, resulting in a reduction in the clearance between the chassis bottom and the road surface, which affects the vehicle's passability. Summary of the Invention

[0004] The purpose of this invention is to provide a secondary telescopic electric pedal for automobiles to solve the problems mentioned in the background art.

[0005] To solve the above-mentioned technical problems, the present invention is achieved through the following technical solution:

[0006] This invention relates to a secondary telescopic electric car pedal, comprising two main bodies. A motor is fixedly connected to the back of the first main body. The pedal also includes:

[0007] The auxiliary mechanism is installed at the bottom of the main body to ensure the support strength of the device during operation when it is deployed.

[0008] When the motor unfolds its internal structure, it stretches the auxiliary mechanism, allowing the auxiliary mechanism to work during the operation of the main body. The auxiliary mechanism ensures the working strength of the device after it is unfolded.

[0009] Furthermore, the main body includes:

[0010] The connecting component is installed at the bottom of the main body;

[0011] Support components are installed at the bottom of the connecting components.

[0012] Furthermore, the auxiliary mechanism includes pedals disposed at the bottom of the two main bodies, and the auxiliary mechanism also includes:

[0013] The elastic component is installed inside the support component;

[0014] The active component is installed on the side wall of the elastic component.

[0015] Furthermore, the connecting assembly includes a connecting plate rotatably connected inside the main body, a hollow plate provided on the side wall of the main body, the top of the hollow plate rotatably connected to the interior of the main body, and the hollow plate snapping into the output end of the first motor. Through the snapping of the hollow plate with the output end of the first motor, the hollow plate can be disassembled from the first motor.

[0016] Furthermore, the support assembly includes a support frame rotatably connected to the side of the connecting plate away from the main body;

[0017] Among them, the end of the hollow plate away from the main body is rotatably connected to the inside of the support frame, and the front of the first support frame is fixedly connected to the motor 2;

[0018] Two inclined grooves are provided on the inner walls of both the front and back sides of the support frame.

[0019] Furthermore, the pedal is rotatably connected between the two support frames, and the side wall of the pedal is snapped into the output end of the second motor. The snapping between the side wall of the pedal and the output end of the second motor facilitates the disassembly and removal of the pedal from the second motor.

[0020] The pedal has two rectangular slots on its side wall. The extension and rotation of the pedal are controlled by motor one and motor two, respectively. This design makes the mechanism of the device more compact. The smaller mechanism reduces the pedal from occupying too much space under the vehicle, which greatly improves the vehicle's passability. When the device needs to be retracted, motor one controls motor two to be retracted to the bottom of the vehicle and then motor two is activated. When motor two is working, it will drive the pedal to rotate and reset.

[0021] Furthermore, the elastic component includes a central shaft that is slidably connected between two inclined slots, and a rotating sleeve is rotatably connected to the outer surface of the central shaft;

[0022] One of the rotating sleeves has several toothed grooves on its outer surface, and these toothed grooves are arranged in a circular array around the central axis.

[0023] A wave plate is fixedly connected to the side of the pedal near the support frame, and the end of the wave plate away from the pedal is rotatably connected to the inside of a rectangular groove.

[0024] Furthermore, the outer surface of the wave plate is in contact with two rotating sleeves, a central rod is fixedly connected between the two wave plates, several semi-circular plates are fixedly connected to the side wall of the wave plate, and sliding grooves are provided on the side wall of the wave plate.

[0025] An intermediate plate is fixedly connected between the two central shafts.

[0026] Furthermore, the movable component includes a sliding plate slidably connected inside the sliding groove, with two protruding rods fixedly connected to both the front and back sides of the sliding plate, and several teeth fixedly connected to the sidewalls of the sliding plate.

[0027] Furthermore, the end of the sliding plate away from the wave plate slides through to the side wall of the hollow plate. A rotating frame is rotatably connected to the side of the sliding plate away from the wave plate. Several tension springs are fixedly connected to the side wall of the rotating frame. The ends of the tension springs away from the rotating frame are fixedly connected to the side wall of the hollow plate. Since the rotating sleeve engages with the teeth on the sliding plate, the rotating frame will be restricted by the sliding plate and stop rotating. When the rotating frame stops rotating, it will restrict the pedal from small-amplitude shaking that may occur when the vehicle is running.

[0028] The present invention has the following beneficial effects:

[0029] 1. This invention enables a more compact design between the components of the device. The smaller size of the components reduces the excessive space occupied by the pedals at the bottom of the vehicle, greatly improving the vehicle's passability. When the device needs to be retracted, motor one controls motor two to be retracted to the bottom of the vehicle and then motor two is activated. When motor two is working, it will cause the pedal to flip and reset. At this time, the pedal will fit against the side skirt of the vehicle body after rotating to a certain angle, presenting state C in Figure 6. This further simplifies the space occupied at the bottom of the vehicle while achieving better efficiency in retraction and matching. It improves the vehicle's aesthetics and passability without having to be hidden at the bottom of the vehicle.

[0030] 2. In this invention, since users generally exert downward force when stepping on the pedal, the wave plate pulls and supports the pedal, while the sliding plate exerts an upward force on the wave plate. This reduces the possibility of the pedal becoming loose or deformed due to play between the pedal and the motor's output shaft when the user steps on it for a long time. At the same time, the contraction of the tension spring on the protruding rod during retraction ensures the timely retraction of the pedal, ensuring the support strength of the pedal for long-term use and improving the pedal's support and retraction efficiency.

[0031] 3. In this invention, when the wave plate is stretched, it will first slide on the surface of the sliding plate through the sliding groove on the wave plate. At this time, the sliding of the wave plate under stretching will drive the rotating sleeve to rotate. Since the rotating sleeve is engaged with the teeth on the sliding plate, the rotating frame will be restricted by the sliding plate and stop rotating. When the rotating frame stops rotating, it will restrict the small amplitude wobbling that the pedal may have when the vehicle is running. At this time, the sliding plate will form a stretching force on the wave plate. By restricting the small amplitude wobbling that the pedal may have when the vehicle is moving, the stability of the pedal when moving with the vehicle can be improved.

[0032] 4. This invention further ensures the synchronicity of the pedal during the flipping process, reducing the uneven force on both sides of the pedal during subsequent use due to tilting after flipping. At the same time, after the connecting plate and hollow plate are retracted by motor one, motor two can be controlled independently to flip the pedal, so that the pedal can be used as a fixed foot support plate in the original position of the vehicle body, further expanding the usage scenarios of the pedal and increasing its practicality and flexibility.

[0033] Of course, any product implementing this invention does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0048] 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.

[0049] Please see Figure 1 - Figure 11 As shown, the present invention is a secondary telescopic electric car pedal, comprising two main bodies 1, wherein a motor 101 is fixedly connected to the back of the first main body 1, and further comprising:

[0050] Auxiliary mechanism 2 is installed at the bottom of the main body 1 to ensure the support strength of the device during operation when the device is deployed.

[0051] When the motor 101 unfolds its internal structure, it stretches the auxiliary mechanism 2, allowing the auxiliary mechanism 2 to work during the operation of the main body 1. The auxiliary mechanism 2 ensures the working strength of the device after it is unfolded.

[0052] Entity 1 includes:

[0053] Connecting component 11 is installed at the bottom of the main body 1;

[0054] Support component 12 is installed at the bottom of connecting component 11.

[0055] The auxiliary mechanism 2 includes pedals 201 disposed at the bottom of the two main bodies 1, and the auxiliary mechanism 2 also includes:

[0056] Elastic component 21 is installed inside the support component 12;

[0057] The movable component 22 is installed on the side wall of the elastic component 21.

[0058] The connecting assembly 11 includes a connecting plate 111 rotatably connected inside the main body 1. A hollow plate 112 is provided on the side wall of the main body 1. The top of the hollow plate 112 is rotatably connected to the interior of the main body 1. The hollow plate 112 is snapped into the output end of the motor 101. By snapping the hollow plate 112 into the output end of the motor 101, the hollow plate 112 and the motor 101 can be detached. When it is necessary to fully unfold the machine for operation, the motor 101 is started. When the motor 101 is working, it will drive the hollow plate 112 to rotate. When the hollow plate 112 rotates, it will drive the support frame 121 to slide.

[0059] The support assembly 12 includes a support frame 121 that is rotatably connected to the connecting plate 111 on the side away from the main body 1;

[0060] Among them, the end of the hollow plate 112 away from the main body 1 is rotatably connected to the inside of the support frame 121, and the front of the first support frame 121 is fixedly connected to the motor 122.

[0061] Two inclined slots 123 are provided on the inner walls of the front and back sides of the support frame 121. When the motor 101 drives the support frame 121 to slide outward and extend out of the bottom of the vehicle body through the hollow plate 112, the pedal 201 will extend out of the bottom of the vehicle body. Then the staff will start the motor 222. When the motor 222 works, it will drive the pedal 201 to make the pedal 201 flip horizontally.

[0062] The pedal 201 is rotatably connected between two support frames 121. The side wall of the pedal 201 is snapped into the output end of the second motor 122. The snapping between the side wall of the pedal 201 and the output end of the second motor 122 facilitates the disassembly and removal of the pedal 201 and the second motor 122.

[0063] The side wall of the pedal 201 has two rectangular slots. The extension and rotation of the pedal 201 are controlled by motor 101 and motor 122 respectively. This design makes the mechanism of the device more compact. The smaller mechanism reduces the excessive space occupied by the pedal 201 at the bottom of the vehicle, which can greatly improve the vehicle's passability. When the device needs to be retracted, motor 101 controls motor 122 to be retracted to the bottom of the vehicle body and then starts motor 122. When motor 122 is working, it will drive the pedal 201 to rotate and reset.

[0064] The elastic component 21 includes a central shaft 212 that is slidably connected between two inclined grooves 123, and a rotating sleeve 213 is rotatably connected to the outer surface of the central shaft 212;

[0065] One of the rotating sleeves 213 has several toothed grooves on its outer surface, and the toothed grooves are arranged in a circular array around the central axis 212.

[0066] A wave plate 211 is fixedly connected to the side of the pedal 201 near the support frame 121. The end of the wave plate 211 away from the pedal 201 is rotatably connected to the inside of the rectangular groove. When one of the central shafts 212 slides, it will drive the other central shaft 212 to slide through the intermediate plate. When the wave plate 211 is pulled by the wave plate 211, the wave plate 211 will be supported by the two rotating sleeves 213 and the central shaft 212, generating a pulling force and a supporting force on the pedal 201. At the same time, the side wall of the wave plate 211 driven by the pedal 201 will drive the sliding plate 221 to slide through the protruding rod 222. At this time, the teeth on the side wall of the sliding plate 221 will move away from the rotating sleeve 213, and the sliding plate 221 will also generate a reverse pulling force on the wave plate 211.

[0067] The outer surface of the wave plate 211 is in contact with two rotating sleeves 213. A central rod 214 is fixedly connected between the two wave plates 211. Several semi-circular plates are fixedly connected to the side wall of the wave plate 211. A sliding groove is provided on the side wall of the wave plate 211.

[0068] An intermediate plate is fixedly connected between the two central shafts 212. When the pedal 201 is retracted, the reset rotation of the pedal 201 will drive the wave plate 211, the central shaft 212 and the rotating sleeve 213 to reset. At the same time, the sliding plate 221 will reset under the contraction potential energy of the tension spring on the rotating frame 223. At this time, the teeth on the sliding plate 221 will engage with the grooves on the rotating sleeve 213.

[0069] The active component 22 includes a sliding plate 221 slidably connected inside the sliding groove. Two protruding rods 222 are fixedly connected to the front and back of the sliding plate 221. Several teeth are fixedly connected to the side wall of the sliding plate 221. Since the rotating sleeve 213 is engaged with the teeth on the sliding plate 221, the rotating frame 223 will be restricted from rotating by the sliding plate 221. When the rotating frame 223 stops rotating, it will restrict the pedal 201 from small-amplitude shaking that may occur when the vehicle is running. At this time, the sliding plate 221 will exert a pulling force on the wave plate 211.

[0070] The end of the sliding plate 221 away from the wave plate 211 slides through to the side wall of the hollow plate 112. The side of the sliding plate 221 away from the wave plate 211 is rotatably connected to the rotating frame 223. Several tension springs are fixedly connected to the side wall of the rotating frame 223. The ends of the tension springs away from the rotating frame 223 are fixedly connected to the side wall of the hollow plate 112. Since the rotating sleeve 213 is engaged with the teeth on the sliding plate 221, the rotating frame 223 will stop rotating due to the restriction of the sliding plate 221. When the rotating frame 223 stops rotating, it will limit the small amplitude wobbling of the pedal 201 that may occur when the vehicle is running.

[0071] In use, the two main bodies 1 are first connected to the bottom of the electric vehicle body. When the pedal is needed, the motor 101 and auxiliary mechanism 2 can be controlled according to the user's needs. When it needs to be fully extended for operation, the motor 101 is started. When the motor 101 is working, it will drive the hollow plate 112 to rotate. When the hollow plate 112 rotates, it will drive the support frame 121 to slide. Then the motor 222 is started. When the motor 222 is working, it will control the pedal 201 to rotate. At this time, the support frame 121 and the pedal 201 will be fully extended from the bottom of the vehicle body for the user to use, thus fulfilling the purpose of the pedal supporting the user.

[0072] When motor 101 drives the support frame 121 to slide outwards through the hollow plate 112 and extend beyond the bottom of the vehicle body, the pedal 201 will also extend beyond the bottom of the vehicle body. Then, the operator activates motor 222. When motor 222 is working, it drives pedal 201, causing pedal 201 to flip horizontally. Since the extension and flipping of pedal 201 are controlled by motors 101 and 222 respectively, this design allows for a more compact mechanism. The smaller mechanism reduces the excessive space occupied by pedal 201 at the bottom of the vehicle, greatly improving the vehicle's passability. When the device needs to be retracted, motor 101 controls motor 222 to retract to the bottom of the vehicle body before activating motor 222. When motor 222 is working, it drives pedal 201 to flip and reset. At this point, pedal 201 will rotate to a certain angle and then fit against the side skirt of the vehicle body, presenting a position as shown in the image. Figure 6 The C-shaped movement mode can further simplify the use of space under the vehicle while achieving better efficiency in retraction and matching. It also improves the vehicle's aesthetics and passability without having to be hidden under the vehicle.

[0073] When motor 2122 rotates pedal 201 and starts motor 101, the rotation of pedal 201 pulls one end of wave plate 211 through the rectangular groove on the side wall. Simultaneously, as pedal 201 rotates, its end pushes one end of wave plate 211. When pedal 201 pulls one end of wave plate 211 through the rectangular groove, wave plate 211 drives one of the central shafts 212 and the rotating sleeve 213 to slide along the guide of the rotating sleeve 213. When one of the central shafts 212 slides... The intermediate plate drives another central shaft 212 to slide. When the wave plate 211 is pulled, it is supported by the two rotating sleeves 213 and the central shaft 212, generating a pulling force and a supporting force on the pedal 201. At the same time, the side wall of the wave plate 211 driven by the pedal 201 will drive the sliding plate 221 to slide through the protruding rod 222. At this time, the teeth on the side wall of the sliding plate 221 will move away from the rotating sleeve 213, and the sliding plate 221 will also generate a reverse pulling force on the wave plate 211, presenting a... Figure 8 In state B, since the user generally exerts a downward pushing force when stepping on pedal 201, the wave plate 211 pulls and supports pedal 201, while the sliding plate 221 exerts an upward pulling force on the wave plate 211. This reduces the possibility of pedal 201 becoming loose or deformed due to play between pedal 201 and the output shaft of motor 222 when the user steps on it for a long time. At the same time, the contraction of the tension spring on the protruding rod 222 when retracting ensures the timely retraction of pedal 201, ensuring the support strength of pedal 201 for long-term use and improving the support and retraction efficiency of pedal 201.

[0074] When pedal 201 is retracted, its reset rotation will cause the wave plate 211, central shaft 212, and rotating sleeve 213 to reset. Simultaneously, sliding plate 221 will reset under the contraction potential energy of the tension spring on rotating frame 223. At this time, the teeth on sliding plate 221 will engage with the grooves on rotating sleeve 213. Since the sidewall of rotating sleeve 213 is in contact with its surface, when pedal 201, which is attached to the vehicle side skirt, vibrates during vehicle operation due to prolonged use and a gap between pedal 201 and the output shaft of motor 212, the vibration of pedal 201 will pull on the wave plate 211. When the wave plate 211 is subjected to… When the wave plate 211 is pulled, it will first slide on the surface of the sliding plate 221 through the sliding groove on the wave plate 211. At this time, the sliding of the wave plate 211 under the pull will drive the rotating sleeve 213 to rotate. Since the rotating sleeve 213 is engaged with the teeth on the sliding plate 221, the rotating frame 223 will stop rotating due to the restriction of the sliding plate 221. When the rotating frame 223 stops rotating, it will limit the small amplitude wobbling that the pedal 201 may have when the vehicle is running. At this time, the sliding plate 221 will form a pulling force on the wave plate 211. By limiting the small amplitude wobbling that the pedal 201 may have when the vehicle is moving, the stability of the pedal 201 when it moves with the vehicle can be improved.

[0075] When the pedal 201 rotates and drives the wave plate 211 to slide, the movement of the wave plate 211 on the side closer to the motor 2 122 will drive the rotation of the other wave plate 211 and the pedal 201 through the central rod 214. At this time, the central rod 214 can form the wave plates 211 on both sides of the pedal 201 into a whole, thus ensuring that the two sides of the pedal 201 rotate synchronously when the motor 2 122 drives the pedal 201 to rotate. This ensures the synchronicity of the pedal 201 during the flipping process and reduces the uneven force on both sides of the pedal 201 during subsequent use due to tilting after flipping. At the same time, after the motor 1 101 controls the connecting plate 111 and the hollow plate 112 to retract, the motor 2 122 can be controlled independently to flip the pedal 201, so that the pedal 201 can form a fixed foot support plate in the original position of the vehicle body. This further expands the usage scenarios of the pedal 201 and increases the practicality and flexibility of the pedal 201.

[0076] Figure 6 The current state is when the device is retracted and the pedal 201 is in contact with the vehicle's side skirt. Figure 8 The B option is in a fully open state. Figure 9 The middle pedal 201 is in the open state when the fixed pedal is in use.
