Description

Technical Field

[0001] This application relates to the field of vehicle technology, and in particular to an auxiliary entry and exit device for vehicles. Background Technology

[0002] To facilitate passenger entry and exit, electric running boards are typically installed below the vehicle doors. These running boards usually consist of a pedal, a four-bar linkage, and a actuator. The pedal is connected to the four-bar linkage, and the actuator moves the pedal between a retracted and extended position via the linkage. However, existing four-bar linkages, when retracted, occupy a relatively large space, making them unsuitable for vehicles with low ground clearance.

[0003] Pedals are generally divided into one-piece structures and spliced ​​structures. Spliced ​​pedals consist of a main body component and end components. Currently, the main body component and end components are usually fixed together by tightening traditional standard bolts one by one. As a result, when assembling and disassembling the pedal, each bolt needs to be loosened one by one, which is time-consuming.

[0004] Application content This application aims to address at least one of the technical problems existing in the prior art. To this end, this application proposes an auxiliary entry and exit device for vehicles, which is adaptable to vehicles with low chassis ground clearance and reduces their installation and removal time.

[0005] An auxiliary entry and exit device for a vehicle according to a first aspect of this application includes a linkage mechanism and a pedal assembly.

[0006] The linkage mechanism includes a mounting base, a movable base, a first link, and a second link. The mounting base is used to install the auxiliary access device on a vehicle. The first link includes a first hinge portion, a second hinge portion, and a first intermediate portion. The first intermediate portion is connected between the first hinge portion and the second hinge portion. The second link includes a third hinge portion, a fourth hinge portion, and a second intermediate portion. The third hinge portion and the fourth hinge portion are connected between the second intermediate portion. The first hinge portion and the third hinge portion are both hinged to the mounting base, and the second hinge portion and the fourth hinge portion are both hinged to the movable base. The pedal assembly includes a main component, an end component, a middle component, and a quick-release mechanism. The main component is mounted on the movable seat. The end component is located on one side of the main component. A first part of the middle component is connected to the main component. A second part of the middle component is detachably connected to the end component via the quick-release mechanism. The first connecting rod is provided with a first limiting step, the second connecting rod is provided with a receiving groove, and the movable seat has an unfolded position or a retracted position. When the movable seat is in the unfolded position, the first limiting step abuts against the second connecting rod. When the movable seat is in the retracted position, at least a portion of the first limiting step is accommodated in the receiving groove.

[0007] The auxiliary entry and exit device for vehicles according to the first aspect of this application has at least the following advantages: When the linkage mechanism moves, the movable seat can switch between an extended position and a retracted position. When the movable seat is in the extended position, the first limiting step abuts against the end of the movable seat near the mounting seat to restrict the movement of the movable seat in the retracted position, so that the movable seat can be stably in the extended position. When the movable seat is in the retracted position, the first limiting step is accommodated in the receiving groove, which can shorten the distance between the first link and the second link, making the linkage mechanism compact and reducing the overall space occupied by the linkage mechanism, thereby adapting to vehicles with a low chassis ground clearance.

[0008] The quick-release mechanism enables detachable connection between the end components and the intermediate components, eliminating the need to tighten or loosen bolts one by one. This significantly shortens the assembly and disassembly time, simplifies the assembly and disassembly steps, effectively improves the efficiency of pedal assembly and disassembly, and enhances the after-sales user experience.

When the movable seat is in the retracted position, a portion of the first connecting rod is accommodated within the first accommodating space. At least one of the first connecting part and the second connecting part has a second limiting step. When the movable seat is in the unfolded position, the first limiting step abuts against the second limiting step.

[0012] In some embodiments, a buffer pad is provided on the second limiting step, the buffer pad is detachably connected to the second limiting step, and when the movable seat is in the retracted position, the projection of the buffer pad is offset from the projection of the first connecting rod in the direction from the movable seat to the mounting seat, and the projection of the buffer pad is offset from the projection of the second connecting rod.

[0024] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that, without conflict, the embodiments and features described herein can be combined arbitrarily with each other.

[0025] In the description of this application, unless otherwise expressly defined, terms such as "setup," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this application in conjunction with the specific content of the technical solution.

[0026] Reference Figures 16 to 17 One embodiment of this application provides an auxiliary entry and exit device for a vehicle, which includes a linkage mechanism, a pedal assembly 100, and a driver 700 (e.g., a motor). The first end of the linkage mechanism is connected to the vehicle body, and the second end is connected to the pedal assembly 100. The driver 700 is connected to the linkage mechanism in a transmission manner, and the driver 700 drives the pedal assembly 100 to move between a retracted position and an extended position through the linkage mechanism.

[0027] Reference Figures 1 to 8One embodiment of the linkage mechanism of this application includes a mounting base 200, a movable base 300, a first link 400, and a second link 500. The mounting base 200 is used to install an auxiliary entry / exit device on a vehicle, the movable base 300 is used to install a pedal assembly 100, one end of the first link 400 is hinged to the mounting base 200, and the other end of the first link 400 is hinged to the movable base 300. The first link 400 is provided with a first limiting step 401. The second link 500... One end of the second link 500 is hinged to the mounting base 200, and the other end of the second link 500 is hinged to the movable base 300. The second link 500 is provided with a receiving groove 501. The movable base 300 has an unfolded position or a retracted position. When the movable base 300 is in the unfolded position, the first limiting step 401 abuts against the second link 500. When the movable base 300 is in the retracted position, part of the first limiting step 401 is accommodated in the receiving groove 501. In this way, the linkage mechanism has a compact structure, which can reduce the overall space occupied by the linkage mechanism, thereby adapting to vehicles with a low chassis ground clearance.

[0028] For example, the first limiting step 401 is located on the side of the first connecting rod 400 facing the second connecting rod 500, and the receiving groove 501 is located on the side of the second connecting rod 500 facing the first connecting rod 400. The two ends of the first connecting rod 400 are hinged to the mounting base 200 and the movable base 300, respectively. The two ends of the second connecting rod 500 are also hinged to the mounting base 200 and the movable base 300, respectively. When either the first connecting rod 400 or the second connecting rod 500 rotates, it causes the movable base 300 to switch between an extended position and a retracted position. When the movable base 300... When in the unfolded position, the first limiting step 401 abuts against the side of the movable seat 300 facing the mounting seat 200 to restrict the movable seat 300 from continuing to move, so that the movable seat 300 can be stably in the unfolded position. When the movable seat 300 is in the retracted position, the first limiting step 401 is accommodated in the receiving groove 501, which can shorten the distance between the first link 400 and the second link 500, making the linkage mechanism compact and reducing the overall space occupied by the linkage mechanism, thereby adapting to vehicles with a low chassis ground clearance.

[0029] It should be noted that when the movable seat 300 is in the unfolded position, the pedal assembly 100 is in the unfolded position; when the movable seat 300 is in the retracted position, the pedal assembly 100 is in the retracted position, and this is not restricted here.

[0030] As another implementation, when the movable seat 300 is in the retracted position, the first limiting step 401 is completely accommodated in the receiving groove 501, making the structure of the linkage mechanism more compact, which is not limited here.

[0031] Reference Figure 12In this embodiment, the first connecting rod 400 includes a first hinge portion 410, a second hinge portion 420, and a first intermediate portion 430. The first intermediate portion 430 is connected between the first hinge portion 410 and the second hinge portion 420. A first limiting step 401 is provided in the first intermediate portion 430 and is located close to the second hinge portion 420. When the movable seat 300 is in the unfolded position, the first limiting step 401 abuts against the side of the movable seat 300 facing the mounting seat 200. The first hinge portion 410 is hinged to the mounting seat 200, and the second hinge portion 420 is hinged to the movable seat 300, which can improve the service life of the first connecting rod 400.

[0032] For example, one end of the first intermediate portion 430 is connected to the first hinge portion 410, and the other end of the first intermediate portion 430 is connected to the second hinge portion 420. Since the first limiting step 401 is located close to the second hinge portion 420, the lever arm between the first limiting step 401 and the second hinge portion 420 can be shortened. When the passenger steps on the pedal assembly 100, the torque on the first link 400 can be reduced. On the one hand, the load-bearing capacity of the first link 400 can be increased, and on the other hand, the bending deformation of the first link 400 can be reduced, thereby increasing the service life of the first link 400.

[0033] Reference Figure 14 In this embodiment, the second connecting rod 500 includes a third hinge portion 510, a fourth hinge portion 520, and a second intermediate portion 530. The third hinge portion 510 and the fourth hinge portion 520 are connected between the second intermediate portion 530. The first end of the receiving groove 501 is located at the third hinge portion 510, and the second end of the receiving groove 501 is located at the second intermediate portion 530. The third hinge portion 510 is hinged to the mounting base 200, and the fourth hinge portion 520 is hinged to the movable base 300. By setting the receiving groove 501 between the third hinge portion 510 and the second intermediate portion 530, the length direction of the receiving groove 501 is matched with the extension and retraction direction of the first connecting rod 400, ensuring that the first limiting step 401 can smoothly embed into the receiving groove 501 when the movable base 300 is retracted, thereby improving the user experience.

[0034] For example, one end of the second intermediate portion 530 is connected to the third hinge portion 510, and the other end of the second intermediate portion 530 is connected to the fourth hinge portion 520. The first end of the receiving groove 501 is located at the third hinge portion 510, and the second end of the receiving groove 501 is located on the side of the second intermediate portion 530 facing the first intermediate portion 430. When the movable seat 300 retracts, the first limiting step 401 passes through the second end of the receiving groove 501 and enters the receiving groove 501, ensuring that the first limiting step 401 can smoothly embed into the receiving groove 501 when the movable seat 300 retracts, thereby improving the user experience.

[0035] Reference Figure 3 , Figure 4and combined Figure 12 In this embodiment, at least a portion of the first intermediate portion 430 is bent, which can increase the structural strength of the first intermediate portion 430, reduce the bending deformation of the first intermediate portion 430, and thus improve the service life of the first connecting rod 400.

[0036] Reference Figure 14 In this embodiment, the second intermediate portion 530 is at least partially bent, which can increase the structural strength of the second intermediate portion 530, reduce the bending deformation of the second intermediate portion 530, and thus improve the service life of the second connecting rod 500.

[0037] It should be noted that the bending shape of the first intermediate part 430 matches the bending shape of the second intermediate part 530. When the movable seat 300 is in the retracted position, the bent parts of the first intermediate part 430 and the bent parts of the second intermediate part 530 are nested together, making the linkage mechanism compact. This not only improves the structural strength of the first intermediate part 430 and the second intermediate part 530, but also reduces the space occupied by the linkage mechanism.

[0038] Reference Figure 3 , Figure 4 and combined Figure 12 In this embodiment, when the movable seat 300 is in the unfolded position, the first section 431 of the first intermediate portion 430 bends in a direction close to the second intermediate portion 530, and the second section 432 of the first intermediate portion 430 bends in a direction away from the second intermediate portion 530. The first limiting step 401 is located between the second section 432 and the second hinge portion 420, and the second intermediate portion 530 bends in a direction away from the first intermediate portion 430. On the one hand, when the first connecting rod 400 is unfolded, the first limiting step 401 is closer to the second hinge portion 420, and the torque formed between the first limiting step 401 and the second hinge portion 420 is shorter, which can enhance the anti-overturning ability of the movable seat 300 in the unfolded position. On the other hand, the bending of the second intermediate portion 530 in a direction away from the first intermediate portion 430 can resist the bending deformation of the first intermediate portion 430, thereby improving the stability of the movable seat 300 in the unfolded position.

[0039] For example, the first section 431 and the second section 432 are generally S-shaped. When the movable seat 300 is in the unfolded position, the first section 431 protrudes in the direction close to the second middle part 530, and the second section 432 protrudes in the direction away from the second middle part 530. The first limiting step 401 is located between the second section 432 and the second hinge part 420. On the one hand, when the first connecting rod 400 is unfolded, the first limiting step 401 is closer to the second hinge part 420, and the torque formed between the first limiting step 401 and the second hinge part 420 is shorter, which can enhance the anti-overturning ability of the movable seat 300 in the unfolded position. On the other hand, the second middle part 530 bends in the direction away from the first middle part 430, which can resist the bending deformation of the first middle part 430, thereby improving the stability of the movable seat 300 in the unfolded position.

[0040] Reference Figure 8 , Figure 9 In this embodiment, when the movable seat 300 is in the retracted position, a portion of the third hinge portion 510 is accommodated in the curved section of the first intermediate portion 430, that is, the curved section wraps around a portion of the second hinge portion 420. In this way, the first link 400 can fit against the second link 500, which can reduce the overall space occupied by the movable seat 300 after it is retracted.

[0041] It should be noted that the first section 431 mentioned above is a curved section, which will not be described again here.

[0042] Reference Figure 6 , Figure 13 In this embodiment, the movable seat 300 includes a main body 311, a first connecting part 312, and a second connecting part 313. Both the first connecting part 312 and the second connecting part 313 are connected to the main body 311. The first connecting part 312 and the second connecting part 313 are arranged opposite each other along the rotation axis of the first connecting rod 400. The main body 311, the first connecting part 312, and the second connecting part 313 enclose a first accommodating space 301. The first connecting rod 400 is hinged to the first connecting part 312 and the second connecting part 313. When the 00 is in the retracted position, part of the first link 400 is housed in the first accommodating space 301. On the one hand, by providing the first connecting part 312 and the second connecting part 313, the hinge stability between the movable seat 300 and the first link 400 can be enhanced, preventing the movable seat 300 from shaking. On the other hand, when the movable seat 300 is in the retracted position, part of the first link 400 is housed in the first accommodating space 301, which can achieve compact storage of the first link 400 and the movable seat 300, thereby reducing the space occupied by the linkage mechanism.

[0043] For example, along the rotation axis of the first link 400, one side of the first link 400 is connected to the end of the first connecting part 312 away from the main body 311, and the other side of the first link 400 is connected to the end of the second connecting part 313 away from the main body 311. The main body 311, the first connecting part 312, and the second connecting part 313 are in a U-shaped structure. The main body 311, the first connecting part 312, and the second connecting part 313 enclose and form a first accommodating space 301. When the movable seat 300 is in the retracted position, part of the first link 400 is accommodated in the first accommodating space 301. On the one hand, this can enhance the hinge stability between the movable seat 300 and the first link 400 and prevent the movable seat 300 from shaking. On the other hand, it can achieve compact storage of the first link 400 and the movable seat 300, thereby reducing the space occupied by the linkage mechanism.

[0044] It should be noted that the main body 311, the first connecting part 312 and the second connecting part 313 are an integral structure, which can reduce the number of molds, thereby reducing the production and manufacturing cost of the molds and thus reducing the production and manufacturing cost of the linkage mechanism. No restrictions are imposed here.

[0045] Reference Figure 13 In this embodiment, both the first connecting part 312 and the second connecting part 313 have a second limiting step 304. The second limiting step 304 is located on the side of the movable seat 300 facing the mounting seat 200. When the movable seat 300 is in the unfolded position, the first limiting step 401 abuts against the second limiting step 304. On the one hand, this can enhance the anti-overturning stability of the movable seat 300 in the unfolded position and prevent the movable seat 300 from shaking. On the other hand, the first limiting step 401 and the second limiting step 304 are in close contact, which can increase the contact area and improve the abutment reliability between the first limiting step 401 and the second limiting step 304, thereby improving the reliability of the linkage mechanism.

[0046] In this embodiment, a buffer pad 305 is provided on the second limiting step 304. The buffer pad 305 is made of elastic material such as rubber or silicone. When the movable seat 300 is in the unfolded position, the first limiting step 401 abuts against the buffer pad 305. The buffer pad 305 can absorb impact energy through elastic deformation, which can eliminate abnormal noise when the movable seat 300 is unfolded, thereby improving the user experience of the auxiliary entry and exit device.

[0047] It should be noted that the buffer pad 305 can reduce the wear and tear on the first limiting step 401 and the second limiting step 304 caused by frequent collisions, and can extend the service life of the first limiting step 401 and the second limiting step 304, which will not be described in detail here.

[0048] In this embodiment, the buffer pad 305 is detachably connected to the second limiting step 304. When the movable seat 300 is in the retracted position, the projection of the buffer pad 305 from the movable seat 300 to the mounting seat 200 is offset from the projection of the first connecting rod 400, and the projection of the buffer pad 305 is also offset from the projection of the second connecting rod 500. That is, the first connecting rod 400 and the second connecting rod 500 do not obstruct the buffer pad 305, which facilitates the disassembly and assembly of the buffer pad 305 and reduces the maintenance cost of the linkage mechanism.

[0049] For example, the buffer pad 305 is detachably connected to the second limiting step 304 by means of threaded connection or snap-fit. In the retracted position, the projection of the buffer pad 305 from the movable seat 300 to the mounting seat 200 is staggered with the projection of the first link 400 and the second link 500. This increases the operating space when assembling and disassembling the buffer pad 305, thereby reducing the maintenance cost of the linkage mechanism. Moreover, it can avoid the additional thickness of the buffer pad 305 affecting the minimum space occupied by the linkage mechanism, ensuring that the linkage mechanism can still be compactly stored.

[0050] Reference Figure 11 In this embodiment, when the movable seat 300 is in the unfolded position, the second link 500 is provided with a first clearance space 502 on the side away from the first link 400. The first clearance space 502 is used to avoid the vehicle body parts, so as to avoid the second link 500 from interfering with the vehicle body parts and to ensure the compact structure of the linkage mechanism.

[0051] Reference Figure 10 In this embodiment, the mounting base 200 is provided with a fifth hinge portion 201, the second connecting rod 500 is hinged to the fifth hinge portion 201, and the movable base 300 is provided with a second clearance space 302. When the movable base 300 is in the retracted position, part of the fifth hinge portion 201 is accommodated in the second clearance space 302 to ensure that the linkage mechanism can still be compactly stored.

[0052] Reference Figure 11 In this embodiment, the mounting base 200 includes a base plate 210, a first side plate 220, and a second side plate 230. The first side plate 220 and the second side plate 230 are both connected to the base plate 210. The first side plate 220 and the second side plate 230 are arranged opposite each other along the rotation axis of the first connecting rod 400. The first connecting rod 400 and the second connecting rod 500 are both connected to the first side plate 220 and the second side plate 230. The first side plate 220 is provided with a third clearance space 202. The third clearance space 202 extends through to the opposite sides of the first side plate 220 along the rotation axis of the first connecting rod 400, which can prevent the mounting base 200 from interfering with the chassis of the vehicle.

[0053] Reference Figure 9 , Figure 14In this embodiment, the linkage mechanism also includes a buffer 600. The buffer 600 is connected to the side of the second link 500 facing the first link 400. When the movable seat 300 is in the retracted position, the buffer 600 abuts against the side of the first link 400 facing the second link 500, which can prevent rigid collision between the first link 400 and the second link 500. The buffer 600 can reduce the noise generated when the movable seat 300 retracts, thereby improving the user experience of the auxiliary entry and exit device.

[0054] For example, the buffer 600 is made of elastic materials such as rubber or silicone. When the movable seat 300 is in the retracted state, the buffer 600 abuts against the side of the first link 400 facing the second link 500. On the one hand, the buffer 600 can absorb impact energy through elastic deformation, which can eliminate abnormal noise when the movable seat 300 is unfolded, thereby improving the user experience of the auxiliary entry and exit device. On the other hand, the buffer 600 can prevent the first link 400 and the second link 500 from shaking.

[0055] In this embodiment, the buffer 600 is provided with a plurality of grooves 610 on the side facing the first connecting rod 400. The plurality of grooves 610 are arranged side by side at intervals and extend through the opposite sides of the buffer 600. The plurality of grooves 610 can increase the deformable area of ​​the buffer 600 when subjected to force, making the buffer 600 easier to compress, thereby improving the buffering effect of the buffer 600.

[0056] For example, along the concave direction of the groove 610, the width of the groove 610 gradually decreases, making the side of the buffer 600 facing the first connecting rod 400 wavy. Multiple grooves 610 can increase the deformable area of ​​the buffer 600 when it is under force, making the buffer 600 easier to compress, thereby improving the buffering effect of the buffer 600.

[0057] Reference Figure 1 , Figure 15 In this embodiment, the mounting base 200 is provided with a first wiring channel 203, through which the vehicle's conductive wire 800 passes. This optimizes the wiring layout of the vehicle, prevents the conductive wire 800 from interfering with the linkage mechanism, and thereby improves the safety and reliability of the vehicle's circuit structure.

[0058] For example, the first wiring channel 203 has a first opening and a second opening, which are located on different sides of the mounting base 200. One end of the conductive wire 800 extends from the first opening into the first wiring channel 203, and the other end of the conductive wire 800 extends out of the first wiring channel 203 through the second opening. This can optimize the wiring layout of the vehicle, prevent the conductive wire 800 from interfering with the linkage mechanism, and thus improve the safety and reliability of the vehicle's circuit structure.

[0059] Reference Figure 1 , Figure 13 In this embodiment, the movable seat 300 is provided with a second wiring channel 303, through which the vehicle's conductive wire 800 passes. This optimizes the wiring layout of the vehicle, prevents the conductive wire 800 from interfering with the linkage mechanism, and thus improves the safety and reliability of the vehicle's circuit structure.

[0060] For example, the second wiring channel 303 has a third opening and a fourth opening. The second wiring channel 303 is located near the side of the movable seat 300 along the rotation axis of the first connecting rod 400. One end of the conductive wire 800 extends from the third opening into the second wiring channel 303, and the other end of the conductive wire 800 extends out of the second wiring channel 303 through the fourth opening. This can optimize the wiring layout of the vehicle, prevent the conductive wire 800 from interfering with the connecting rod mechanism, and thus improve the safety and reliability of the vehicle's circuit structure.

[0061] Reference Figure 5 , Figure 13 In this embodiment, the movable seat 300 includes a first component 310 and a second component 320. The first component 310 and the second component 320 are detachably connected, and the first component 310 and the second component 320 enclose a second wiring channel 303, which facilitates the arrangement of conductive wires 800 in the second wiring channel 303, thereby reducing the assembly and maintenance difficulty of the conductive wires 800.

[0062] For example, the first component 310 includes a main body 311, a first connecting part 312 and a second connecting part 313. The second component 320 is detachably connected to the first component 310 by bolts or snap-fit, which makes it easy to arrange the conductive wire 800 in the second wiring channel 303, thereby reducing the assembly and maintenance difficulty of the conductive wire 800.

[0063] Reference Figure 12 In this embodiment, two first limiting steps 401 are configured. The two first limiting steps 401 are spaced apart along the rotation axis of the first connecting rod 400, and a second accommodating space 402 is formed between the two first limiting steps 401. When the movable seat 300 is in the retracted position, part of the second connecting rod 500 is accommodated in the second accommodating space 402, which can improve the anti-overturning ability of the movable seat 300 in the unfolded position. When the movable seat 300 is in the retracted position, it can reduce the overall space occupied by the linkage mechanism to adapt to vehicles with a low chassis height.

[0064] Combination Figures 16 to 20As shown, in some embodiments, the pedal assembly includes a main component 110a, an end component 110b, and a connecting assembly 140. The end component 110b is located on one side of the main component 110a. The connecting assembly 140 includes an intermediate component 150 and a quick-release mechanism 160. A first part of the intermediate component 150 is connected to the main component 110a, and a second part of the intermediate component 150 is detachably connected to the end component 110b via the quick-release mechanism 160. Compared with the prior art, this application achieves a detachable connection between the end component 110b and the intermediate component 150 through the quick-release mechanism 160, eliminating the need to tighten or loosen bolts one by one. This significantly shortens the assembly and disassembly time, simplifies the assembly and disassembly steps, effectively improves the efficiency of pedal assembly and disassembly, and enhances the after-sales user experience. It should be noted that the end component 110b can be located on one side of the main component 110a in the length or width direction.

[0065] Because the pedal is relatively long, it is prone to interference with the vehicle lift during assembly on the automobile assembly line. Therefore, the end member 110b in this application is located on one side of the main member 110a along its length. While keeping the overall length of the pedal constant, this application sets the lengths of the main member 110a and the end member 110b according to requirements, setting the length of the end member 110b to be significantly larger than that of conventional thin-plate closures. Thus, when the vehicle is on the lift, the main member 110a and the intermediate member 150 can be installed first, avoiding the interference area of ​​the lift; after the vehicle is removed from the lift, the end member 110b is assembled using the quick-release mechanism 160.

[0066] Reference Figures 16 to 20 In some embodiments, the end member 110b has a first through hole 110b1; the quick-release mechanism 160 includes a handle 161, a pivot 162, and a connecting rod 163. The handle 161 is movably connected to the connecting rod 163 via the pivot 162. After passing through the first through hole 110b1, the connecting rod 163 is limitedly connected to the intermediate member 150. With the above structure, the handle 161 serves as a force application point. By applying force to the handle 161, the user can drive the connecting rod 163 to move vertically, thereby connecting or separating the connecting rod 163 from the intermediate member 150, thus achieving the fixation or separation between the end member 110b and the main member 110a.

[0067] Reference Figures 16 to 20 In some embodiments, the second part of the intermediate member 150 has an internally threaded hole 151, and a portion of the connecting rod 163 passes through the first through hole 110b1 and is threadedly connected to the internally threaded hole 151. With the above structure, the user can rotate the handle 161 to drive the connecting rod 163 to rotate along the internally threaded hole 151, thereby causing the connecting rod 163 to move in the vertical direction.

[0068] In some embodiments, the connecting rod 163 and the intermediate member 150 are connected by a snap-fit ​​mechanism, making assembly and disassembly more convenient.

[0069] In some embodiments, the second part of the intermediate member 150 has a second through hole (not shown in the figure), and the bottom of the connecting rod is connected to a limiting part (not shown in the figure) extending radially along the connecting rod. After the limiting part completely passes through the first through hole and the second through hole, the handle is operated to move the limiting part until the limiting part abuts against the intermediate member to form the limiting connection between the connecting rod 163 and the intermediate member 150. The handle abuts against the end member to maintain the limiting connection between the connecting rod 163 and the intermediate member 150. The operation is convenient and quick.

[0070] In some embodiments, the cross-section of the second through hole is non-circular, and the cross-sectional shape of the limiting part is adapted to the cross-sectional shape of the first through hole 110b1. After the limiting part completely passes through the first through hole 110b1 and the second through hole, the limiting part is offset relative to the second through hole by rotating the handle 161. The offset part abuts against the back side of the intermediate member 150 to form a limiting connection between the connecting rod 163 and the intermediate member 150. By rotating the handle 161, the limiting part is rotated and shifted to form an abutment limit, realizing the quick locking or unlocking of the end member 110b and the intermediate member 150 without rotating and twisting the connecting rod 163 to complete the thread engagement, further shortening the disassembly and assembly time and improving disassembly efficiency. Optionally, the non-circular shape includes, but is not limited to, polygons (such as triangles, quadrilaterals, crosses), ellipses, or other shapes combining straight lines and arcs.

[0071] Reference Figures 18 to 20 In some embodiments, the quick-release mechanism 160 further includes a gasket 164, and the connecting rod 163 passes through the gasket 164, the end member 110b, and the intermediate member 150 in sequence; the handle 161 has an eccentric wheel portion 1611 and a force-applying arm 1612, the eccentric wheel portion 1611 is connected to the force-applying arm 1612, the rotating shaft 162 passes through the eccentric wheel portion 1611, and the end of the gasket 164 facing the eccentric wheel portion 1611 has a concave arc surface 1641, which abuts against the outer surface of the eccentric wheel portion 1611.

[0072] Through the above structure, the gasket 164 acts as a force transition and isolation component, separating the eccentric wheel portion 1611 from the end member 110b, thus avoiding direct friction and scratching between the eccentric wheel portion 1611 and the end member 110b during rotation, effectively extending the service life of the end member 110b. Simultaneously, the eccentric structure formed by the eccentric wheel portion 1611 and the rotating shaft 162, combined with the guiding effect of the concave arc surface 1641 on the eccentric wheel portion 1611, allows the eccentric wheel portion 1611 to rotate smoothly along the concave arc surface 1641 when the force-applying arm 1612 is rotated. The locking and unlocking of the handle 161 is achieved through the change in distance from the outer circumferential surface of the eccentric wheel portion 1611 to the rotating shaft 162.

[0073] When it is necessary to unlock the handle 161, the lever arm 1612 of the handle 161 is turned, causing the eccentric wheel 1611 to rotate in the forward direction. This gradually reduces the contact area between the eccentric wheel 1611 and the concave arc surface 1641, thus reducing the clamping force between them and achieving the unlocked state. When it is necessary to lock the handle 161, the lever arm 1612 is operated, causing the eccentric wheel 1611 to rotate in the reverse direction. This gradually increases the contact area between the eccentric wheel 1611 and the concave arc surface 1641, forming a stable clamping fit between them and achieving reliable locking.

[0074] Reference Figures 18 to 20 In some embodiments, one end of the connecting rod 163 is connected to a support block 165, and the support block 165 has a through hole 1651; the rotating shaft 162 passes through the through hole 1651 to realize the movable connection between the handle 161 and the connecting rod 163; when the connecting rod 163 is limited to the intermediate member 150, the support block 165 abuts against the surface of the gasket 164.

[0075] With the above structure, when the connecting rod 163 is connected to the intermediate component 150 in a limited position, the support block 165 abuts against the surface of the gasket 164, so that the support block 165 and the gasket 164 form a limited fit. When the connecting rod 163 and the intermediate component 150 are connected in a limited position, the height of the connecting rod 163 relative to the assembly is limited, improving the stability of the force during locking, thereby ensuring the reliability of the quick release mechanism 160.

[0076] Reference Figures 18 to 20 In some embodiments, the eccentric wheel portion 1611 includes a first eccentric wheel portion 16111 and a second eccentric wheel portion 16112. The first eccentric wheel portion 16111 and the second eccentric wheel portion 16112 are aligned and spaced apart to form a slot 1613, and the support block 165 is located at the slot 1613.

[0077] Through the above structure, the support block 165 and the eccentric wheel 1611 form a fitted structure, effectively limiting the relative wobbling between the support block 165 and the eccentric wheel 1611, and improving the stability of the linkage between the handle 161 and the connecting rod 163. Since the first eccentric wheel 16111 and the second eccentric wheel 16112 clamp the support block 165 between them, rotational force can be applied to both sides of the support block 165 simultaneously, avoiding deformation of the support block 165 caused by local stress concentration on one side, and enhancing the overall structural strength of the quick-release mechanism 160. This is especially suitable for the technical solution of threaded connection between the connecting rod 163 and the intermediate component 150.

[0078] Reference Figures 18 to 20 In some embodiments, the head of the first through hole 110b1 has a rounded surface 110b2; the bottom of the gasket 164 has a spherical portion 1642, which abuts against the rounded surface 110b2. The spherical portion 1642 at the bottom of the gasket 164 and the rounded surface 110b2 at the head of the first through hole 110b1 form a spherical fit. Compared with planar contact, the force-bearing area is increased, the contact stress is reduced, and cracks or plastic deformation are prevented from occurring at the edge of the opening of the first through hole 110b1 due to stress concentration, effectively improving the reliability of locking the handle 161.

[0079] Reference Figures 18 to 20 In some embodiments, the second part of the intermediate member 150 has a spare threaded hole 152 or a first spare through hole (not shown in the figure), and the end member 110b has a second spare through hole 110b6, which is aligned with the spare threaded hole 152 or the first spare through hole.

[0080] With the above structure, the spare threaded hole 152 or the first spare through hole of the intermediate component 150 is aligned with the second spare through hole 110b6 of the end component 110b, forming an additional connection path. When the internal threaded hole 151 fails, the quick-release mechanism 160 can be assembled into the spare threaded hole 152 or the first spare hole to extend the overall service life of the pedal. The second part of the intermediate component 150 preferentially uses the spare threaded hole 152, so that when both the quick-release mechanism 160 and the internal threaded hole 151 fail, the intermediate component 150 and the end component 110b can be connected using ordinary bolts, effectively extending the overall service life of the pedal.

[0081] Reference Figures 18 to 20In some embodiments, to ensure reliable fixation of the end member 110b, multiple intermediate members 150 are provided. Each intermediate member 150 is connected to at least one quick-release mechanism 160 and has at least one spare threaded hole 152 or a first spare through hole. Exemplarily, two intermediate members 150 are provided, each intermediate member 150 is connected to one quick-release mechanism 160 and additionally has one spare threaded hole 152.

[0082] Reference Figures 18 to 20 In some embodiments, the end member 110b has a mounting cavity 110b3 at its bottom; the pedal assembly 100 also includes a cover (not shown in the figure), which is detachably connected to the end member 110b and covers the mounting cavity 110b3 to close the mounting cavity 110b3, and the handle 161 is located in the mounting cavity 110b3.

[0083] With the above structure, the cover and end component 110b are detachably connected and seal the mounting cavity 110b3, storing the handle 161 inside the mounting cavity 110b3. This not only protects the handle 161, pivot 162 and other components, preventing mud, water stains and debris from entering and causing jamming, rust and wear, thus extending the service life of the quick-release mechanism 160, but also improves the overall appearance of the pedal. At the same time, it prevents the quick-release mechanism 160 from being scratched due to exposure, improving the safety of use. The detachable design of the cover also facilitates subsequent maintenance of the internal handle 161 and other components.

[0084] As an example, the cover and the end component 110b are connected by a snap-fit ​​mechanism. The cover is provided with an elastic snap, and the end component 110b is provided with a corresponding slot. The elastic snap and the slot engage with each other to achieve quick assembly and disassembly of the cover and the end component 110b, which facilitates the inspection and maintenance of components such as the handle 161 in the mounting cavity 110b3.

[0085] As an example, the end member 110b has a corresponding threaded hole, and the cap is fastened to the end member 110b by bolts, so that the connection is firm and reliable.

[0086] Reference Figures 18 to 20 In some embodiments, the handle 161 has a locking position relative to the end member 110b. When the handle 161 is in the locking position, the handle 161 abuts against the cover. In this way, the cover limits the locking handle 161, preventing the handle 161 from rotating in the unlocking direction, effectively reducing the possibility of the handle 161 unlocking on its own under vehicle vibration conditions, thereby improving the stability of the handle 161 locking.

[0087] Reference Figures 16 to 20In some embodiments, the end member 110b has crisscrossing reinforcing ribs 110b4 located within the mounting cavity 110b3. The reinforcing ribs 110b4 enhance the deformation resistance of the mounting cavity 110b3, thereby improving the structural strength of the end member 110b and effectively resisting external forces caused by stepping and vibration, reducing the probability of deformation of the end member 110b, and extending the service life of the end member 110b.

[0088] Reference Figures 18 to 20 In some embodiments, the main body member 110a has a first receiving groove 110a1 inside, the first receiving groove 110a1 extending along the length direction of the main body member 110a; the end member 110b has a second receiving groove 110b5 inside, the second receiving groove 110b5 extending along the length direction of the end member 110b; a first part of the intermediate member 150 is located in the first receiving groove 110a1, and a second part of the intermediate member 150 is located in the second receiving groove 110b5.

[0089] With the above structure, the intermediate component 150 is embedded in the receiving groove, which reduces the erosion and damage of the external environment and does not occupy the external space of the pedal, making the overall shape of the pedal simpler and flatter; at the same time, the first receiving groove 110a1 and the second receiving groove 110b5 can limit and support the intermediate component 150, effectively restricting the offset and shaking of the intermediate component 150, facilitating the hole alignment operation between the intermediate component 150 and the main component 110a and the end component 110b, and facilitating assembly.

[0090] In some embodiments, the main component 110a and the end component 110b are connected by multiple plug-in structures, which facilitates quick alignment during assembly and improves assembly efficiency. The plug-in structures also enhance the structural strength and stress stability of the connection, improving the overall rigidity and vibration resistance of the pedal.

[0091] Exemplarily, the main component 110a has a first insertion port 110a2, and the end component 110b has a first insertion protrusion 110b7. The first insertion port 110a2 and the first insertion protrusion 110b7 form an insertion structure. The first insertion protrusion 110b7 is inserted into the first insertion port 110a2 to realize the insertion and engagement of the main component 110a and the end component 110b.

[0092] Exemplarily, the main body component 110a has a second insertion protrusion and the end component 110b has a second insertion port. The second insertion protrusion and the second insertion port form a plug-in structure. The second insertion protrusion is inserted into the second insertion port to achieve the plug-in engagement between the main body component 110a and the end component 110b.

[0093] Among them, multiple plug-in structures are located at least partially on the upper layer of the first receiving groove 110a1 and the second receiving groove 110b5. The plug-in mating structure is closer to the foot surface of the pedal than the first receiving groove 110a1 and the second receiving groove 110b5, which can effectively resist the external force of footing and effectively improve the structural strength and deformation resistance of the pedal.

[0094] Reference Figures 18 to 20 In some embodiments, the mounting base 200 has fixing holes 211 for connecting to the vehicle body; the main component 110a has a clearance channel 110a3; under vertical visual projection, the fixing holes 211 are located within the clearance channel 110a3. With this structure, the main component 110a has a clearance channel 110a3, and under vertical visual projection, the fixing holes 211 are located within the clearance channel 110a3, providing operating space for the assembly of the linkage mechanism and the vehicle body. This facilitates the installation of fasteners such as bolts from the clearance channel 110a3, effectively reducing interference caused by the main component 110a to the assembly operation and improving the ease of assembly.

[0095] Reference Figures 18 to 20 In some embodiments, the pedal assembly 100 further includes a cover member connected to the main body member 110a to cover the clearance channel 110a3, thereby optimizing the overall appearance of the pedal and making its shape more aesthetically pleasing. Exemplarily, the cover member 170 is a contour filler block (not shown in the figure), which is adapted to the contour of the clearance channel 110a3, filling and sealing the clearance channel 110a3 to ensure a smooth and continuous appearance of the pedal.

[0096] In some embodiments, the pedal assembly 100 further includes a panel 120 and a fastener 130, with the main body 110, panel 120, and fastener 130 being separately disposed. The main body 110 has a first slot 111. The panel 120 has a flat portion 121 and an insertion portion 122, the insertion portion 122 being fixedly connected to the flat portion 121, the flat portion 121 being disposed on the main body 110. The fastener 130 is disposed within the first slot 111. The fastener 130 includes a main body 131. The main body 131 has a second slot 1311, for example, the main body 131 being U-shaped or W-shaped. The insertion portion 122 is inserted into the second slot 1311. The first sidewall of the second slot 1311 has a first elastic claw 132 and a second elastic claw 133, and the second sidewall of the second slot 1311 also has a first elastic claw 132 and a second elastic claw 133, the first sidewall and the second sidewall being located on opposite sides of the insertion portion 122. The first elastic claw 132 abuts against the side wall of the insertion part 122 and applies a first fastening force to the insertion part 122, and the second elastic claw 133 abuts against the main body member 110 and applies a second fastening force to the main body member 110, so as to achieve a fixed connection between the panel 120 and the main body member 110.

[0097] The first elastic claws 132 located on both sides of the insertion part 122 clamp the insertion part 122, thus achieving a fixed connection between the fastener 130 and the insertion part 122. Therefore, during the assembly of the pedal assembly, the fastener 130 is first assembled onto the insertion part 122, and then the insertion part 122 with the fastener 130 is inserted into the first slot 111, improving the assembly efficiency of the pedal assembly 100. The panel 120 is fixedly connected to the main component 110 via the fastener 130. In this way, the assembly difficulty of the pedal assembly 100 is reduced (i.e., assembly efficiency is improved), the connection between the panel 120 and the main component 110 is strengthened, and the occurrence of panel 120 warping or hollow areas (i.e., bulges) between the panel and the main component 110 is reduced, while also improving the overall aesthetics of the pedal assembly 100.

[0098] In some embodiments, the first slot 111 is a strip-shaped groove extending longitudinally along the vehicle. Multiple fasteners 130 are provided, spaced apart longitudinally along the vehicle to form multiple fixing points on the insertion portion 122, further improving the tightness between the panel 120 and the main body member 110, further reducing the incidence of panel 120 warping or hollow areas (i.e., bulges) between the panel and the main body member 110, and extending the service life of the pedal assembly 100 to some extent.

[0099] In some embodiments, two insertion portions 122 and two first slots 111 are provided. The two insertion portions 122 are distributed at a lateral interval along the vehicle, and the two insertion portions 122 are inserted into the two first slots 111 in a one-to-one correspondence. In this way, both ends of the panel 120 in the lateral direction of the vehicle are constrained, limiting the lateral movement of the panel 120 along the vehicle, while further improving the connection strength between the main body component 110 and the panel 120.

[0100] In some embodiments, the fastener 130 includes a first fastener 134 and a second fastener 135. The first fastener 134 is located in one of a plurality of first slots 111, and the second fastener 135 is located in one of the remaining first slots 111. The first fastener 134 and the second fastener 135 are longitudinally offset. In this way, the number of fasteners 130 is reduced while ensuring the connection strength between the main body member 110 and the panel 120, thereby saving costs.

[0101] Please refer to the following: Figure 1 and Figure 2In some embodiments, the main body component 110 is provided with a limiting groove 112, and the flat plate portion 121 is located within the limiting groove 112. When the panel 120 is installed onto the main body component 110, the limiting groove 112 can quickly position the flat plate portion 121, further simplifying the assembly steps and reducing the assembly difficulty, while restricting the movement of the panel 120.

[0102] Please refer to the following: Figure 1 , Figure 2 and Figure 5 In some embodiments, the panel 120 further includes a folded edge 123 fixedly connected to the edge of the flat plate portion 121. The folded edge 123 is spaced apart from the insertion portion 122 to form a third slot 124. One sidewall of the first slot 111 is inserted into the third slot 124, such that the folded edge 123, the insertion portion 122, and the two sidewalls of the first slot 111 form a labyrinth structure. This labyrinth structure, without the need for a seal, can effectively prevent foreign objects such as gravel and mud from entering the first slot 111, thereby reducing the risk of the pedal assembly 100 jamming, parts wear, or abnormal noise during vehicle operation due to the accumulation of foreign objects, thus improving the reliability of the pedal assembly 100.

[0103] In some embodiments, the front and rear sidewalls of the limiting groove 112 are both V-shaped (not shown in the figure), and the openings of the V-shapes are all oriented towards the center of the panel, thereby enabling the limiting groove to limit the panel in multiple directions. In addition, when the panel 120 is installed onto the main body member 110, the V-shaped sidewalls can provide guidance and positioning for the panel 120, thereby simplifying assembly and improving assembly efficiency.

[0104] In some embodiments, a sealing structure (not shown) is provided between the panel 120 and the main body member 110 to prevent foreign objects from entering the first slot 111 or the limiting groove 112, thereby reducing damage or abnormal noise caused by foreign objects to the pedal assembly 100, and thus improving the reliability of the pedal assembly 100 and extending its service life. Further, the sealing structure may be a sealing strip provided at the connection between the panel 120 and the main body member 110 or a sealant applied at the connection between the panel 120 and the main body member 110.

[0105] In some embodiments, the flat plate portion 121 of the panel 120 is provided with a plurality of positioning posts 125, which are spaced apart. The main body component 110 is provided with a plurality of connecting holes 113. The plurality of positioning posts 125 are inserted into the plurality of connecting holes 113 in a corresponding manner and are interference-fitted to further improve the connection strength between the main body component 110 and the panel 120.

[0106] In some embodiments, the main component 110 is provided with a light-emitting element (not shown) to provide illumination at night or in dimly lit environments, or to indicate the position and boundaries of the pedal assembly 100, thereby improving the safety and convenience of passengers getting in and out of the vehicle. Furthermore, the light-emitting element has different colors and illumination modes (such as constant light, flashing, or dynamic welcome lighting) to serve as ambient lighting or status indicator lights for the vehicle.

[0107] It should be noted that, without affecting the understanding of this application, some structural features are not shown in the accompanying drawings.

[0108] The embodiments of this application have been described in detail above with reference to the accompanying drawings. However, this application is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of this application.
