Description

Technical Field

[0001] This utility model belongs to the field of automotive parts technology, specifically relating to an electric pedal telescopic bracket. Background Technology

[0002] For vehicles with higher chassis, such as SUVs, jeeps, and commercial vehicles, installing foot pedals at the bottom of the doors can provide drivers with a better experience when getting in and out of the vehicle.

[0003] Currently, electric retractable running boards not only function as foot pedals but can also be retracted under the vehicle when not in use, maintaining the vehicle's overall aesthetic appeal and harmony. Furthermore, during vehicle operation, electric retractable running boards do not affect the vehicle's width or chassis height, nor do they reduce its ground clearance. In vehicle configuration options, electric retractable running boards are gradually replacing fixed running boards and have become the mainstream choice.

[0004] However, most electric retractable pedals on the market are driven by a linkage mechanism. During the extension and retraction of the pedal, the linkage mechanism occupies a large amount of space and is prone to bumping into obstacles under the vehicle during the extension and retraction process, causing the pedal to fail or be damaged, affecting the user experience and service life of the electric retractable pedal. Utility Model Content

[0005] To address the shortcomings of the prior art, this utility model provides an electric pedal telescopic bracket, which sets the first receiving cavity and the telescopic component into an arc-shaped structure, making the telescopic component occupy less space during movement and preventing it from bumping into obstacles under the vehicle; under the protection of the shell, the telescopic component and the drive gear set are not affected by the external environment, resulting in a longer service life; at the same time, it has lower requirements for external power sources and is easier to install overall.

[0006] The technical effect to be achieved by this utility model is realized through the following technical solution: This utility model provides an electric pedal telescopic bracket, comprising: The housing includes an upper cover, a lower cover, and a first receiving cavity formed by the upper cover and the lower cover, the first receiving cavity including an outlet communicating with the outside; A telescopic kit includes a telescopic member disposed in the first receiving cavity, the telescopic member having a toothed surface on the side facing the upper cover; and Drive components, including drive gear sets; The first receiving cavity and the telescopic member have an arc-shaped structure, and the upper cover and the toothed surface are both located on the protruding side of the first receiving cavity and the telescopic member; the upper cover has a second receiving cavity that communicates with the first receiving cavity, the drive gear set is disposed in the second receiving cavity and meshes with the toothed surface, driving the telescopic member to extend out of the extension port or to retract the telescopic member into the first receiving cavity.

[0007] In some implementations, the drive gear set includes a drive shaft and a drive gear. The drive shaft is rotatably disposed in the second receiving cavity and extends through the upper cover to be driven and connected to an external power source. The drive gear is fixed on the drive shaft. The drive shaft rotates to drive the telescopic member to move within the first receiving cavity.

[0008] In some implementations, the drive gear set further includes a driven gear, which is rotatably disposed in the second receiving cavity and meshes with the toothed surface and the driving gear respectively.

[0009] In some implementations, the drive component further includes a support adjustment spring, which is fixedly disposed in the second receiving cavity and has an elastic abutment end. The driven gear has a rotating shaft, which is floatingly disposed in the second receiving cavity. The elastic abutment end abuts against the rotating shaft, so that the driven gear and the driving gear are tightly meshed.

[0010] In some implementations, the telescopic member includes a guide portion and an extension portion. The guide portion is disposed within the first receiving cavity, and the extension portion extends from the guide portion toward the extension opening. The lower cover has a blocking slope at the extension opening, the blocking slope being inclined toward the first receiving cavity. A stop slope matching the blocking slope is provided at the connection between the guide portion and the extension portion, and the stop slope abuts against the blocking slope, thereby restricting the guide portion within the first receiving cavity.

[0011] In some implementations, the lower cover has a limiting chamfer on the outward side of the protrusion, and the protrusion has a limiting protrusion on the side facing the lower cover. When the telescopic member is retracted into the first receiving cavity, the limiting protrusion abuts against the limiting chamfer.

[0012] In some implementations, the telescopic kit includes a first roller rotatably disposed on the side of the guide portion facing the upper cover. The upper cover is provided with a guide rail portion that matches the first roller. The first roller cooperates with the guide rail portion and abuts against the upper cover.

[0013] In some implementations, the telescopic kit further includes a second roller, which is rotatably disposed on the side of the guide portion facing the lower cover and near the cut-off slope. The lower cover has a guide surface, and when the telescopic member moves, the second roller rolls and abuts against the guide surface.

[0014] In some implementations, a pedal mounting portion is provided at the end of the telescopic member away from the first receiving cavity, and the pedal mounting portion is fixedly connected to an external foot pedal.

[0015] In some implementations, a protective component is also included, which includes a first fixed end, a second fixed end, and a telescopic protective portion disposed between the first fixed end and the second fixed end; the first fixed end is fixedly connected to the housing at the protrusion position, the second fixed end is fixed to the side of the pedal mounting portion facing the first receiving cavity, and the portion of the telescopic component extending out of the protrusion side is wrapped by the telescopic protective portion.

[0016] In summary, this utility model has at least the following advantages: 1. The electric pedal telescopic bracket provided by this utility model sets the first receiving cavity and the telescopic component into an arc-shaped structure, and allows the telescopic component to extend out of the opening or retract into the first receiving cavity. The telescopic component occupies less movement space during movement compared with the prior art, and will not collide with obstacles under the vehicle when telescopic, thus avoiding telescopic failure or damage to components.

[0017] 2. The electric pedal telescopic bracket provided by this utility model, under the protection of the shell, prevents the telescopic components and drive gear set from being affected by the external environment. Especially when driving on rough roads such as gravel and mud or when the pedal is telescopic, pollutants such as sand, mud, and dust will not enter the shell, ensuring that the telescopic components and drive gear set can work normally and have a longer overall service life.

[0018] 3. The electric pedal telescopic bracket provided by this utility model has a drive gear set that matches the tooth profile of the telescopic component, which reduces the requirements for the external power source of the drive telescopic component and lowers the cost of external power source accessories. The modular kit assembled from the shell, telescopic kit and drive component reduces the installation difficulty and overall installation cost compared to the existing technical solutions.

[0030] To facilitate understanding of this utility model, a more comprehensive description will be given below with reference to the accompanying drawings and specific embodiments. The drawings illustrate preferred embodiments of this utility model. However, this utility model can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to provide a more thorough and complete understanding of the disclosure of this utility model.

[0031] It should be noted that when a component is said to be "fixed to" another component, it can be directly attached to the other component or there may be an intervening component. When a component is said to be "connected to" another component, it can be directly connected to the other component or there may be an intervening component.

[0032] In the description of this utility model, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the product of this utility model is in use. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first," "second," and "third," etc., are only used to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0033] 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.

[0034] Example 1: Please see Figures 1-4 This embodiment provides an electric pedal telescopic bracket 100 for use on an electric pedal in a car, providing telescopic movement for the pedal, allowing the pedal to extend outwards or be hidden under the vehicle. The electric pedal telescopic bracket 100 includes a housing 1, a telescopic assembly 2, and a drive component 3. The telescopic assembly 2 and the drive component 3 are disposed within the housing 1, and the drive component 3 drives the telescopic assembly 2 to telescopically move within the housing 1.

[0035] Specifically, the housing 1 includes an upper cover 11, a lower cover 12, and a first receiving cavity 13 formed by the upper cover 11 and the lower cover 12. The first receiving cavity 13 includes an extension opening 131 communicating with the outside. The telescopic kit 2 includes a telescopic member 21, which is disposed in the first receiving cavity 13 and has a toothed surface 211 on the side facing the upper cover 11. The drive component 3 includes a drive gear set 31.

[0036] More specifically, the first receiving cavity 13 and the telescopic member 21 have an arc-shaped structure, and the upper cover 11 and the toothed surface 211 are both located on the protruding side of the first receiving cavity 13 and the telescopic member 21. The upper cover 11 is provided with a second receiving cavity 111 that communicates with the first receiving cavity 13. The drive gear set 31 is disposed in the second receiving cavity 111 and meshes with the toothed surface 211 to drive the telescopic member 21 to extend out of the extension port 131 or to retract the telescopic member 21 into the first receiving cavity 13.

[0037] The electric pedal telescopic bracket 100 is generally installed in the space under the vehicle 300, with the protruding side of the telescopic member 21 facing the vehicle. When the telescopic member 21 moves in the first receiving cavity 13 and extends from the extension opening 131, the movement trajectory of the telescopic member 21 is consistent with the space of the first receiving cavity 13, and it does not occupy the space on the recessed side. Therefore, it will not bump into obstacles under the vehicle during extension and retraction, especially on uneven road surfaces. This avoids situations where the pedal extension and retraction is restricted or components are damaged due to bumping into obstacles during extension and retraction.

[0038] Normally, the foot pedal is located at the end of the telescopic member 21. Due to its arc-shaped structure, the telescopic member 21 also moves and extends along an arc-shaped path. The electric foot pedal telescopic bracket 100 does not need to maintain a sufficient distance from the vehicle floor to achieve the height difference between the foot pedal and the door, thus enabling the foot pedal to be moved between the door and the ground to form a step. Therefore, the electric foot pedal telescopic bracket 100 occupies less space, further reducing its impact on the vehicle floor height.

[0039] The telescopic component 21 and the drive gear set 31 are housed inside the housing 1. Under the protection of the housing 1, external contaminants such as sand and mud cannot enter the interior of the housing 1 and affect the meshing action of the telescopic component 21 and the drive gear set 31. This ensures that the telescopic component 21 and the drive gear set 31 can work normally under any harsh road conditions, and the overall service life of the electric pedal telescopic bracket 100 is longer.

[0040] Furthermore, because the telescopic component 21, with its arc-shaped structure and toothed surface 211, functions as a part of a large-diameter gear when meshing with the drive gear set 31, it achieves a larger reduction ratio by engaging with the smaller drive gear set 31, thus reducing the external power source requirements for driving the telescopic component 21. This allows even a small, high-speed, low-torque drive motor to easily drive the telescopic component 21, reducing the cost of external power source components. The modular kit, consisting of the housing 1, telescopic assembly 2, and drive component 3, is separate from the external power source. Compared to existing technologies, when installed under the vehicle, the electric pedal telescopic bracket 100 and the external power source components can be installed separately, eliminating the need for initial assembly before lifting to the vehicle floor, thus reducing installation difficulty.

[0041] Furthermore, under gear meshing conditions with a large reduction ratio, the telescopic component 21 moves more smoothly, resulting in lower noise and less wear compared to existing linkage mechanisms. Simultaneously, the modular electric pedal telescopic bracket 100 is suitable for various vehicle types, including jeeps and commercial vehicles. By adjusting the number of electric pedal telescopic brackets 100 and the size of the external power source as needed, mass production of the electric pedal telescopic bracket 100 is possible, reducing production costs.

[0042] In some embodiments, the drive gear set 31 includes a drive shaft 311 and a drive gear 312. The drive shaft 311 is rotatably disposed in the second receiving cavity 111 and extends through the upper cover 11 to be driven and connected to an external power source. The drive gear 312 is fixed on the drive shaft 311, so that the drive gear 312 can be driven to rotate by the drive shaft 311. When the drive shaft 311 rotates, it drives the telescopic member 21 to move within the first receiving cavity 13, thereby realizing the telescopic action of the telescopic member 21.

[0043] Furthermore, the drive gear set 31 also includes a driven gear 313, which is rotatably disposed in the second receiving cavity 111 and meshes with the tooth surface 211 and the driving gear 312 respectively. The driven gear 313 is disposed between the tooth surface 211 and the driving gear 312 to adjust the meshing clearance between the driving gear 312 and the tooth surface 211, thereby reducing noise during rotational meshing. Compared to the driving gear 312 directly meshing with the tooth surface 211, the presence of the driven gear 313 results in more stable meshing between the gear and the tooth surface 211, and the clearance is adjustable and controllable.

[0044] More specifically, the drive component 3 also includes a support and adjustment spring 32, which is fixedly disposed within the second receiving cavity 111 and has an elastic abutment end 321. The driven gear 313 has a rotating shaft 3131, which is floatingly disposed within the second receiving cavity 111. The elastic abutment end 321 abuts against the rotating shaft 3131, causing the driven gear 313 to mesh tightly with the driving gear 312. In this embodiment, the support and adjustment spring 32 is a torsion spring. Please refer to [link to previous text]. Figure 2 and Figure 4 The main body of the supporting adjusting spring 32 is fixed to one side inside the second receiving cavity 111, with its end away from the second receiving cavity 111 abutting against the upper cover 11. The opposite end is an elastic abutment end 321, which extends into the second receiving cavity 111 and "lifts" the rotating shaft 3131 from the first receiving cavity 13 toward the second receiving cavity 111. The driven gear 313 is subjected to force and meshes tightly with the driving gear 312. When the drive gear set 31 drives the telescopic member 21 to move, the driven gear 313 is not affected by the reverse force of the telescopic member 21 and is not pushed by the telescopic member 21 to the side away from the driving gear 312.

[0045] In summary, the electric pedal telescopic bracket provided in this embodiment sets the first receiving cavity and the telescopic component into an arc-shaped structure, and allows the telescopic component to extend out of the opening or retract into the first receiving cavity. The telescopic component occupies less movement space during movement compared to the prior art, and will not collide with obstacles under the vehicle during extension and retraction, thus avoiding extension failure or damage to components.

[0046] Secondly, under the protection of the housing, the telescopic components and drive gear set are not affected by the external environment. Especially when driving on rough roads such as gravel and mud or when the pedal is extended or retracted, pollutants such as sand, mud, and dust will not enter the housing, ensuring that the telescopic components and drive gear set can work normally and have a longer overall service life.

[0047] In addition, the tooth profile of the drive gear set and the telescopic component makes the external power source requirements of the drive telescopic component lower, reducing the cost of external power source components. The modular kit assembled from the housing, telescopic kit and drive components is easier to use and lowers the overall installation cost compared to existing technical solutions.

[0048] Example 2: This embodiment makes further structural optimizations based on Embodiment 1. Please refer to... Figures 1-4 Based on the above, refer to Figures 5-8 This embodiment differs from Embodiment 1 in that the telescopic member 21 includes a guide portion 212 and an extension portion 213. The guide portion 212 is disposed within the first receiving cavity 13, and the extension portion 213 extends from the guide portion 212 toward the extension opening 131. The lower cover 12 has a blocking slope 121 at the extension opening 131, which is inclined toward the first receiving cavity 13. A stop slope 214 matching the blocking slope 121 is provided at the connection between the guide portion 212 and the extension portion 213. The stop slope 214 abuts against the blocking slope 121, thereby confining the guide portion 212 within the first receiving cavity 13.

[0049] Driven by the drive gear set 31, the extension 213 extends out of the housing 1 or retracts into the first receiving cavity 13. When the telescopic member 21 extends to its final position, the stop slope 214 abuts against the blocking slope 121, providing a limit to the extension member 21's position and ensuring accurate positioning. Simultaneously, the external power source does not require precise control to achieve accurate extension, thus expanding the range of external power source options.

[0050] In a further embodiment, to ensure that the telescopic member 21 is accurately positioned during retraction and to prevent collisions between the telescopic member 21 and the inner wall of the first receiving cavity 13 or impacts to the foot pedal on the outside, the lower cover 12 has a limiting chamfer 122 on the outward side of the protrusion 131, and a limiting protrusion 2131 is provided on the side of the protrusion 213 facing the lower cover 12. When the telescopic member 21 is retracted into the first receiving cavity 13, the limiting protrusion 2131 abuts against the limiting chamfer 122. In this embodiment, the limiting chamfer 122 is located on the side of the lower cover 12 facing the concave arc-shaped structure. When the telescopic member 21 is driven back into the first receiving cavity 13, the limiting protrusion 2131 will abut against the bottom of the housing 1 before the guide portion 212, preventing internal collision damage.

[0051] In some embodiments, the telescopic kit 2 includes a first roller 22, which is rotatably disposed on the side of the guide portion 212 facing the upper cover 11. The upper cover 11 is provided with a guide rail portion 112 that matches the first roller 22. The first roller 22 cooperates with the guide rail portion 112 and abuts against the upper cover 11. The first rollers 22 are arranged in pairs on the guide portion 212. When the telescopic member 21 is driven to extend outward or retract, the first roller 22 is forced upward to press against the guide rail portion 112 and rolls smoothly along the guide rail portion 112, reducing the frictional resistance during the movement of the telescopic member 21 and also reducing the wear of the telescopic member 21 on the housing 1, thereby improving the service life of the electric pedal telescopic bracket 100.

[0052] In this embodiment, in addition to the first roller 22, the telescopic assembly 2 also includes a second roller 23. The second roller 23 is rotatably disposed on the side of the guide portion 212 facing the lower cover 12 and is located near the cutoff slope 214. The lower cover 12 is provided with a guide surface 123. When the telescopic member 21 moves, the second roller 23 rolls and abuts against the guide surface 123. The second roller 23 is also arranged in pairs on the telescopic member 21. Due to the constantly changing force direction during movement, the second roller 23 bears forces in other directions that the first roller 22 cannot bear. Similar to the first roller 22, the second roller 23, after being subjected to force, abuts against and rolls on the guide surface 123 to reduce driving resistance and further improve the smoothness of movement of the telescopic member 21.

[0053] More specifically, the upper cover 11, lower cover 12, and telescopic component 21 can be die-cast, injection-molded, or 3D printed. On the non-working surfaces, hollowing out the parts can reduce their weight, or structural reinforcement such as herringbone ribs can be used to strengthen the upper cover 11, lower cover 12, and telescopic component 21, thus reducing the overall weight while ensuring the structural strength of the parts.

[0054] Example 3: This embodiment, based on Embodiments 1 and 2 above, provides an electric pedal telescopic bracket 100. Please refer to... Figures 1-8Based on this, refer to Figures 9-10 The difference lies in that a pedal mounting portion 215 is provided at the end of the telescopic member 21 away from the first receiving cavity 13, and the pedal mounting portion 215 is fixedly connected to the external foot pedal 200. The external foot pedal 200 is a contact element for the user's foot to step on. During manufacturing, the pedal mounting portion 215 is integrally formed with the other structures of the telescopic member 21, allowing the final extension angle of the external foot pedal 200 to be determined in advance. The external foot pedal 200 only needs to be fixedly connected to the pedal mounting portion 215. Compared to existing technical solutions that require fixing other components such as the drive component 3 to the external foot pedal 200, the electric pedal telescopic bracket 100 provided in this embodiment has a simpler assembly method and higher assembly efficiency.

[0055] Furthermore, in this embodiment, the electric pedal telescopic bracket 100 also includes a protective member 4. The protective member 4 includes a first fixed end 41, a second fixed end 42, and a telescopic protective portion 43 disposed between the first fixed end 41 and the second fixed end 42. The first fixed end 41 is fixedly connected to the housing 1 at the protrusion 131 position, and the second fixed end 42 is fixed to the side of the pedal mounting portion 215 facing the first receiving cavity 13. The side of the telescopic member 21 extending out of the protrusion 131 is covered by the telescopic protective portion 43. On the side of the pedal mounting portion 215 facing the housing 1, the protective member 4 can effectively prevent external contaminants such as mud, dust, and gravel from entering through the gap between the protrusion 131 and the telescopic member 21, avoiding external contaminants from accelerating the wear of components in the first receiving cavity 13 and the second receiving cavity 111, and extending the overall service life of the electric pedal telescopic bracket 100.

[0056] In this embodiment, the protective component 4 is a stainless steel accordion-style cover or a nylon fabric accordion-style cover. In other embodiments, the protective component 4 may also be an elastically telescopic type of cover.

[0057] The above description is merely an example and illustration of the structure of this utility model, and while the description is quite specific and detailed, it should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these obvious substitutions all fall within the protection scope of this utility model.
