Description

Technical Field

[0001] The utility model relates to the technical field of vehicle side pedals, and in particular to a side pedal driving mechanism. The utility model also relates to a vehicle provided with the side pedal driving mechanism. Background Art

[0002] Currently, the chassis of some vehicles, such as commercial vehicles and SUVs, are relatively high relative to the ground, making it inconvenient for passengers to get on or off the vehicle. Therefore, many vehicles are equipped with side steps to facilitate passengers getting on or off the vehicle.

[0003] Side steps typically come in fixed or electrically retractable styles (referred to as electric side steps). Side steps increase the width of the vehicle, but since fixed side steps are non-retractable, they can make it difficult to pass other vehicles and navigate narrow passages while the vehicle is moving. Electric retractable side steps can be extended or retracted. They can be extended when passengers need to board or exit the vehicle, and retracted while the vehicle is moving, making it easier to pass other vehicles and navigate narrow passages.

[0004] Traditional electric running boards utilize a planar four-bar linkage formed by a main transmission mechanism and a driven mechanism, which is then driven to deploy and retract the board. This four-bar linkage can only deploy and retract the board in a specific position, not in any position. Furthermore, this type of drive mechanism is complex, making it difficult to deploy in compact vehicles and resulting in high manufacturing costs. Utility Model Content

[0005] In view of this, the present invention aims to provide a side pedal driving mechanism, which has a simplified structure, is easy to manufacture and assemble, and is conducive to reducing costs.

[0006] In order to achieve the above-mentioned purpose, the technical solution of the utility model is achieved as follows:

[0007] A side step drive mechanism comprises a mounting frame provided on a vehicle body, a rotary drive device provided on the mounting frame, and a transmission assembly provided between the rotary drive device and the side step;

[0008] The transmission assembly includes a transmission gear connected to the drive shaft of the rotary drive device, and a transmission rod slidably arranged on the mounting frame along the width direction of the vehicle, the transmission rod is provided with transmission teeth meshing with the transmission gear, and the side pedal is connected to the transmission rod;

[0009] When the rotary drive device drives the transmission gear to rotate, the transmission gear can drive the transmission rod to slide along the width direction of the vehicle, so that the side step is translated to the deployed position or the stowed position.

[0010] Furthermore, a connecting block is fixedly mounted on the driving shaft of the rotary driving device; and the transmission gear is connected to the connecting block via a connecting bracket.

[0011] Furthermore, the connecting block is detachably connected to the driving shaft; and / or the connecting bracket is detachably connected to the connecting block.

[0012] Furthermore, the transmission gear and the connecting bracket are integrally formed.

[0013] Furthermore, the transmission rod is provided with a groove arranged along the width direction of the vehicle, and the transmission teeth are respectively provided on the inner walls on both sides of the groove. The transmission gear is located in the groove and meshes with the transmission teeth on both sides.

[0014] Furthermore, the mounting frame includes a first bracket connected to the vehicle body, and a second bracket connected to the first bracket; the rotation drive device is provided on the first bracket, and the transmission rod is slidably provided in a mounting groove on the second bracket.

[0015] Furthermore, a pedal bracket is provided at one end of the transmission rod, and the side pedal is connected to the pedal bracket.

[0016] Furthermore, the rotation drive device includes a drive motor and a reducer connected to the drive motor, and the drive shaft is a power output shaft of the reducer.

[0017] Furthermore, the motor shaft of the drive motor is arranged horizontally, and the axial direction of the drive shaft is arranged vertically along the height direction of the vehicle.

[0018] Compared with the prior art, the present invention has the following advantages:

[0019] The side step driving mechanism described in the present invention realizes the translational expansion and storage of the side step in the width direction of the vehicle by adopting a gear rack mechanism transmission form formed by a transmission gear and transmission teeth on a transmission rod. It not only ensures the reliability of the side step during movement and can realize the expansion and storage of the side step at any position, but also simplifies the structure, is easy to manufacture and assemble, and is also conducive to reducing costs.

[0020] Furthermore, the provision of the connecting block not only reduces the axial dimension of the drive shaft, allowing it to be shorter and thus reducing costs, but also provides space for the installation of the transmission gear and the connecting bracket, facilitating the arrangement of the transmission gear and ensuring smooth power transmission. The connecting block is detachably connected to the drive shaft, facilitating its installation and removal from the drive shaft and facilitating replacement of the drive unit. The connecting bracket is detachably connected to the connecting block, facilitating the installation and removal of the transmission gear from the connecting block.

[0021] Secondly, the transmission gear and connecting bracket are integrally formed, resulting in a simple structure, easy processing and preparation, and a high degree of integration. This also facilitates the miniaturization of the transmission gear design and ensures the structural stability of the transmission gear. A groove is provided on the transmission rod, and transmission teeth are formed on the inner walls of both sides of the groove to engage with the transmission gear. This allows the transmission teeth on both sides to mesh with the transmission gear, which helps improve transmission stability and enhances the smoothness and reliability of the movement of the transmission rod, namely the side pedal.

[0022] Furthermore, the mounting bracket includes a first bracket and a second bracket, so that the rotary drive device is disposed on the first bracket and the transmission rod is slidably disposed in a mounting groove on the second bracket. This simple structure facilitates design and implementation, and also facilitates the arrangement of the rotary drive device and the transmission rod. Simultaneously, the transmission rod slides in the mounting groove, providing a certain degree of guidance for the movement of the transmission rod, thereby ensuring the accuracy of the direction of movement of the transmission rod. A pedal bracket is provided at one end of the transmission rod, facilitating the connection between the side pedal and the pedal bracket, and thus facilitating the connection between the transmission rod and the side pedal, while also ensuring the reliability of the connection between the transmission rod and the side pedal.

[0023] Furthermore, the rotary drive unit utilizes a drive motor and a reducer, with the reducer's power output shaft forming the drive shaft. This helps maintain the output speed of the transmission gear, thereby ensuring that the side steps do not move too slowly or too quickly during deployment or stowage, thereby improving their usability. The drive motor's shaft is arranged horizontally, with the drive shaft's axial direction arranged vertically along the vehicle's height, resulting in a more compact structure and easier placement on the vehicle.

[0024] Another object of the present invention is to provide a vehicle, wherein the vehicle is provided with an electric side step, and the electric side step has the side step driving mechanism as described above.

[0025] The vehicle of the present invention and the side step driving mechanism described above have the same beneficial effects as those of the prior art, and will not be described in detail here. BRIEF DESCRIPTION OF THE DRAWINGS

[0041] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0042] Example 1

[0043] This embodiment relates to a side-step driving mechanism, which is applied to an electric side step in a vehicle. The side-step driving mechanism has a simplified structure, is easy to manufacture and assemble, and is conducive to reducing costs.

[0044] In terms of overall structure, Figures 1 to 3 As shown, the side step driving mechanism of this embodiment includes a mounting frame 1 provided on the vehicle body, a rotation driving device 2 provided on the mounting frame 1 , and a transmission assembly provided between the rotation driving device 2 and the side step 5 .

[0045] The transmission assembly includes a transmission gear 23 connected to the drive shaft 21 of the rotary drive device 2, and a transmission rod 3 slidably mounted on the mounting frame 1 along the width of the vehicle. The transmission rod 3 is provided with transmission teeth 30 that mesh with the transmission gear 23, and the side step 5 is connected to the transmission rod 3. When the rotary drive device 2 drives the transmission gear 23 to rotate, the transmission gear 23 can drive the transmission rod 3 to slide along the width of the vehicle, causing the side step 5 to translate to the deployed position or the stowed position.

[0046] At this time, the mounting frame 1 is set on the vehicle body, which can provide support and layout basis for the entire drive mechanism. The rotational driving force output by the rotary drive device 2 drives the transmission gear 23 to rotate, and the transmission gear 23 engages with the transmission teeth 30 on the transmission rod 3, and drives the transmission rod 3 to slide in the width direction of the vehicle, so that the side pedal 5 is translated to the deployment position or the storage position. In this structure, the gear rack mechanism transmission form formed by the transmission gear 23 and the transmission teeth 30 on the transmission rod 3 is adopted to realize the translation deployment and storage of the side pedal 5 in the width direction of the vehicle. It not only ensures the reliability of the use of the side pedal 5 during the movement, and can realize the deployment and storage of the side pedal 5 at any position, but also simplifies the structure, makes it easy to manufacture and assemble, and is also conducive to reducing costs.

[0047] It is worth noting that the transmission gear 23 cooperates with the transmission teeth 30 on the transmission rod 3, allowing the transmission rod 3 to be moved to any position and maintained in that position, and also to be retracted from any position under the vehicle body. This allows the deployed and retracted positions of the side steps 5 to be adjusted in real time according to actual needs, thereby improving the user experience.

[0048] Based on the overall introduction above, in detail, as a preferred embodiment, in this embodiment, the mounting frame 1 includes a first bracket 11 connected to the vehicle body, and a second bracket 12 connected to the first bracket 11. The rotation drive device 2 is disposed on the first bracket 11, and the transmission rod 3 is slidably disposed in a mounting groove 120 on the second bracket 12. Here, the mounting frame 1 includes the first bracket 11 and the second bracket 12. Its structure is simple, easy to design and implement, and also facilitates the arrangement of the rotation drive device 2 and the transmission rod 3. At the same time, the transmission rod 3 slides in the mounting groove 120, which provides a certain degree of guidance for the movement of the transmission rod 3, ensuring the accuracy of the movement direction of the transmission rod 3.

[0049] Specifically, if Figures 1 to 3 As shown, combined with Figure 4 and Figure 6 As shown, the first bracket 11 is a flat plate-shaped structure, and the rotary drive device 2 is screwed to the first bracket 11 via a threaded connector. The first bracket 11 is also provided with a through-hole 110 for the drive shaft 21 of the selective drive device to pass through, thereby facilitating better engagement and connection between the transmission gear 23 and the transmission rod 3. The second bracket 12 comprises a rectangular tube with a mounting slot 120 therein, and a connecting plate attached to the side of the rectangular tube for connection to the vehicle body.

[0050] The transmission rod 3 is movably inserted into a mounting slot 120 within the rectangular tube. Multiple connecting plates are spaced apart on either side of the rectangular tube, each with a vehicle body connection hole 121. These holes 121 are used to connect the second bracket 12, or mounting bracket 1, to the vehicle body. In practice, mounting bracket 1 is secured to the vehicle body, for example, by bolts threaded through the holes 121.

[0051] The first bracket 11 and the second bracket 12 are connected together via a first connector 10. Specifically, the first connector 10 includes a connecting sleeve located between the first bracket 11 and the second bracket 12, and a threaded connector inserted into the connecting sleeve. The ends of the threaded connector are respectively threadedly connected to the first bracket 11 and the second bracket 12. In this embodiment, the threaded connector is preferably a bolt. The bolt passes through the through hole on the first bracket 11, the connecting sleeve, and the through hole on the second bracket 12 in sequence, and is threadedly connected to a nut on the side of the second bracket 12 away from the first bracket 11. In this way, the first bracket 11 and the second bracket 12 are connected as a whole via the connector.

[0052] The design of the first bracket 11 and the second bracket 12 makes the overall structure of the mounting bracket 1 simpler, easier to process and prepare, and reduces manufacturing costs.

[0053] It should be noted here that, in addition to the above-mentioned structural forms, the first bracket 11 and the second bracket 12 in this embodiment may also adopt other structural forms. For example, on the basis of the first bracket 11 being set as a flat plate structure, the second bracket 12 is also set as a flat plate structure, and two long strips are arranged at intervals on the second bracket 12 of the flat plate structure. The two long strips extend along the width direction of the vehicle. At this time, the gap between the two long strips forms an installation groove 120. At this time, the transmission rod 3 can be slidably in the installation groove 120 formed between the two long strips. This is also possible.

[0054] See Figures 1 to 3 As shown, in this embodiment, as a preferred embodiment, a pedal bracket 4 is provided at one end of the transmission rod 3, and the side pedal 5 is connected to the pedal bracket 4. The provision of the pedal bracket 4 here facilitates the connection between the transmission rod 3 and the side pedal 5, and also ensures the reliability of the connection between the transmission rod 3 and the side pedal 5.

[0055] In specific implementation, the pedal bracket 4 can be secured to the end of the transmission rod 3 by welding or screwing. A slot is formed on the pedal bracket 4 that matches the side of the side step 5. The pedal bracket 4 is inserted into the side step 5 from one side. A T-block 41 is provided between the pedal bracket 4 and the side step 5, and the T-block 41 can be retained on the side step 5. The side step 5 is connected to the pedal bracket 4 by a third connecting member 42 that passes through a through hole in the pedal bracket 4 and is screwed onto the T-block 41. It should be noted that the side step 5 can also be connected to the pedal bracket 4 using other structural forms known in the art.

[0056] As a preferred embodiment, in this embodiment, a connecting block 22 is fixedly mounted on the drive shaft 21 of the rotary drive device 2, and a transmission gear 23 is connected to the connecting block 22 via a connecting bracket 230. With this arrangement, the connecting block 22 fixed to the drive shaft 21 rotates synchronously with the drive shaft 21, and the rotation of the connecting block 22 can drive the transmission gear 23 to rotate synchronously.

[0057] In this structure, the connection block 22 can, on the one hand, reduce the axial dimension of the drive shaft 21, making the drive shaft 21 shorter and thus reducing costs. On the other hand, it provides space for the installation of the transmission gear 23 and the connection bracket 230, facilitating the arrangement of the transmission gear 23 and ensuring smooth power transmission. Furthermore, the combination of the connection block 22 and the connection bracket 230 can miniaturize the transmission gear 23, thereby contributing to a lightweight design and cost reduction.

[0058] It should be pointed out that, in this embodiment, in addition to being arranged on the connecting block 22 in the above structure, the transmission gear 23 can also be arranged directly on the drive shaft 21, but in this case the size of the transmission gear 23 needs to be designed to be larger.

[0059] In this embodiment, see Figures 2 to 4 The connecting block 22 is detachably connected to the drive shaft 21, which facilitates installation and removal of the connecting block 22 from the drive shaft 21 and also facilitates replacement of the drive device. Specifically, the connecting block 22 is provided with fixing holes arranged along the radial direction of the drive shaft 21, and a notch is provided on the drive shaft 21. By fitting the inclined surface of a wedge-shaped block inserted into the fixing hole with the notch, and locking the wedge-shaped block in the fixing hole so that the inclined surface of the wedge-shaped block abuts against the notch, a fixed connection between the connecting block 22 and the drive shaft 21 is achieved.

[0060] It is worth noting that, in addition to being fixed to the drive shaft 21 in the above-mentioned structural form, the connecting block 22 can also be locked to the drive shaft 21 by, for example, screwing a fastener 221 provided in a fixing hole to a threaded hole on the drive shaft 21. In order to ensure the limiting effect of the connecting block 22 in the axial direction of the drive shaft 21,

[0061] In this embodiment, as a preference, the connecting bracket 230 is detachably connected to the connecting block 22. This arrangement is conducive to the installation and removal of the transmission gear 23 on the connecting block 22. For details, see Figure 4 and Figure 5 As shown, in this embodiment, a transmission gear 23 is fixedly mounted in the middle of a connecting bracket 230, and mounting holes 232 are provided at both ends of the connecting bracket 230. Corresponding to these mounting holes 232, threaded holes are also provided at the bottom of the connecting block 22. A second connecting member 231, which passes through the mounting holes 232 and is screwed into the threads, allows the connecting bracket 230 to be detachably connected to the connecting block 22.

[0062] It is understandable that, in addition to being detachably connected to the connection block 22 by screw connection, the connection bracket 230 can also be connected to the connection block 22 by snap connection or plug connection, and such an arrangement is also acceptable.

[0063] As a further preferred embodiment, in this embodiment, the transmission gear 23 and the connecting bracket 230 are integrally formed. This simple structure allows for ease of fabrication and a high degree of integration, facilitates miniaturization of the transmission gear 23, and ensures the structural stability of the transmission gear 23. In practice, if the transmission gear 23 and the connecting bracket 230 are made of steel, they can be cast, for example, and then machined. Of course, the transmission gear 23 and the connecting bracket 230 can also be injection molded, provided they meet structural strength requirements.

[0064] Combine Figure 2 、 Figure 3 and Figure 7 As shown, in this embodiment, a groove 31 is provided on the transmission rod 3 along the width of the vehicle. Transmission teeth 30 are provided on the inner walls of each side of the groove 31. The transmission gear 23 is located within the groove 31 and meshes with the transmission teeth 30 on both sides. The meshing connection between the transmission teeth 30 and the transmission gear 23 is achieved by forming transmission teeth 30 on the inner walls of the groove 31. This improves transmission stability and enhances the smoothness and reliability of the movement of the transmission rod 3, and thus the side step 5.

[0065] It is worth mentioning here that in addition to providing a groove 31 on the transmission rod 3 and forming a transmission tooth 30 on the inner walls on both sides of the groove 31, it is also possible to directly form a transmission tooth 30 on the side of the transmission rod 3 that is engaged with the transmission gear 23, that is, the rack structure in the prior art, which is also possible.

[0066] In addition, as a preferred embodiment, in this embodiment, the rotation drive device 2 includes a drive motor 201 and a reducer 202 connected to the drive motor 201, and the drive shaft 21 is the power output shaft of the reducer 202. This arrangement helps to ensure the output speed of the transmission gear 23, thereby ensuring that the movement speed of the side step 5 is neither too slow nor too fast during the deployment or storage process, thereby improving the use effect.

[0067] Furthermore, as a preferred embodiment, the motor shaft of the drive motor 201 is arranged horizontally, and the axial direction of the drive shaft 21 is arranged vertically along the height direction of the vehicle. This arrangement can make the structure more compact and also facilitates arrangement on the vehicle.

[0068] In addition, it should be noted that, based on the fact that the side pedal 5 extends along the length direction of the vehicle and is relatively long in the length direction of the vehicle, and on the basis of being provided with the driving mechanism of this embodiment, in order to ensure the smooth deployment and storage of the side pedal 5, a telescopic rod structure can also be provided between the vehicle body and the side pedal 5. The telescopic rod structure is spaced apart from the driving mechanism in the length direction of the vehicle, and the telescopic rod structure, for example, includes a first rod body connected to the vehicle body, and a second rod body slidably provided on the first rod body. Relative to one end connected to the first rod body, the other end of the second rod body is connected to the side pedal 5. Furthermore, a synchronization rod can also be provided between the second rod body and the transmission rod 3, and the two ends of the synchronization rod are fixedly connected to the second rod body and the transmission rod 3, so that the smoothness of the movement of the side pedal 5 during deployment and storage can be further improved.

[0069] Of course, it is understandable that two sets of side step drive mechanisms of this embodiment can be arranged at a distance between the side step 5 and the vehicle body. By using two drive motors 201 to simultaneously drive the corresponding transmission gears 23 to rotate synchronously, and drive the two transmission rods 3 to extend or retract synchronously, the side step 5 can also be smoothly deployed and stored.

[0070] The side step driving mechanism of this embodiment adopts a gear rack mechanism transmission form formed by the transmission gear 23 and the transmission teeth 30 on the transmission rod 3, so as to realize the translational expansion and storage of the side step 5 in the width direction of the entire vehicle. It not only ensures the reliability of the use of the side step 5 during movement, and can realize the expansion and storage of the side step 5 at any position, but also simplifies the driving structure of the electric side step, makes it easy to manufacture and assemble, and is also conducive to reducing costs, and has a good use effect.

[0071] Example 2

[0072] This embodiment relates to a vehicle provided with an electric side step, and the electric side step has the side step driving mechanism of the first embodiment.

[0073] The vehicle of this embodiment can realize the translational expansion and folding of the side pedal 5 by adopting the side pedal drive mechanism in Example 1, and it is also conducive to simplifying the drive structure, facilitating manufacturing and assembly layout, helping to reduce costs, and having a good use effect.

[0074] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
