[0002] With the development of vehicle technology, electric pedals have emerged.

[0003] The electric pedal can switch between a retracted position and an extended position via a pedal mechanism. When passengers get on or off the vehicle, the pedal is switched to the extended position for easy access and to improve the user experience.

[0004] In related technologies, the pedal device includes a drive component and a linkage assembly. The pedal is located on the linkage assembly, and the drive component drives the linkage assembly to rotate, thereby driving the pedal to switch between a retracted position and an extended position.

Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0073] See Figure 1 , Figure 1 A schematic diagram of the pedal device 1000 provided in one embodiment of this application is shown. In this embodiment, the length direction of the vehicle is the Y direction, and the width direction of the vehicle is the X direction.

[0074] This embodiment provides a vehicle, which includes a vehicle body and a pedal device 1000. The pedal device 1000 is disposed on the vehicle body and is used for passengers to step on when getting on and off the vehicle, so as to improve the comfort, convenience and sense of ceremony of passengers getting on and off the vehicle.

[0075] Specifically, there are at least two sets of pedal devices 1000. The pedal devices 1000 are located on the vehicle body in the width direction X, so that pedal devices 1000 are provided on both sides of the vehicle, making it convenient for drivers and passengers to get on and off the vehicle from both sides.

[0076] like Figure 1 and Figure 2 As shown, the pedal device 1000 includes a drive member 100, a linkage assembly 200, and a pedal 300. The linkage assembly 200 is connected to the output end of the drive member 100, and the pedal 300 is disposed on the linkage assembly 200. The drive member 100 drives the linkage assembly 200 to rotate, thereby driving the pedal 300 to switch between the extended position and the retracted position.

[0077] like Figure 2 and Figure 3As shown, the linkage assembly 200 further includes a first linkage 210 and a second linkage 220. The first linkage 210 can be connected to the output end of the drive member 100. The second linkage 220 has a first mounting space 2213a, a portion of the first linkage 210 is located in the first mounting space 2213a and rotatably connected to the second linkage 220. The second linkage 220 includes a reinforcing member 222 disposed in the first mounting space 2213a. During the movement of the pedal 300 from the retracted position to the extended position, the gap between the reinforcing member 222 and the first linkage 210 gradually increases. This gradual change in direction causes the reinforcing member 222 to form an arc or structure on the side facing the first mounting space 2213a. This makes the distance from the side of the reinforcing member 222 facing the first mounting space 2213a to the first connecting rod 210 larger in the middle and smaller on both sides. When the pedal 300 moves from the retracted position to the extended position, this gradual distance allows larger foreign objects in the gap to fall out from the larger gap in the middle. This helps improve the ability of the connecting rod assembly 200 to discharge foreign objects, reduces the amount of foreign objects remaining in the connecting rod assembly 200, and guides the flow of mud, sand, snow, and other foreign objects accumulated in the gap of the connecting rod assembly 200. This makes it easier for foreign objects accumulated in the gap of the connecting rod assembly 200 to fall off naturally, facilitating the discharge of foreign objects and avoiding problems such as wear, abnormal noise, or even breakage caused by foreign objects remaining in the gap of the connecting rod assembly 200. This helps to improve the service life of the connecting rod assembly 200.

[0078] Especially in rainy or snowy weather or after driving on unpaved roads, vehicles are prone to carrying a large number of foreign objects or throwing them into the gaps of the connecting rod assembly 200. The reinforcement 222 is designed so that even if foreign objects enter the gaps of the connecting rod assembly 200, they can be more easily dislodged from the larger gap between the reinforcement 222 and the first connecting rod 210 during vehicle acceleration, deceleration, or bumpy driving, thus preventing them from accumulating inside the connecting rod assembly 200.

[0079] In some of these embodiments, such as Figure 7 As shown, further, the side of the reinforcing member 222 facing the first mounting space 2213a is the mating side 2222. Along the length direction Y of the vehicle, the distance from the mating side 2222 to the first connecting rod 210 gradually decreases from both sides towards the middle. This gradual change causes the mating side 2222 to form an arc-shaped structure, that is, the distance from the mating side 2222 to the first connecting rod 210 is larger in the middle and smaller on both sides. When the connecting rod assembly 200 switches from the retracted position to the extended position, foreign objects near the sides slide towards the middle during extension and fall off smoothly from the larger gap in the middle.

[0080] For example, when the diameter of the foreign object between the mating side 2222 and the first link 210 is larger than the gap size on both sides, the foreign object moves towards the middle during the movement of the vehicle or the movement of the link assembly 200 because the gap between the mating side 2222 and the first link 210 in the middle position is larger, thereby causing the foreign object to fall off in the middle.

[0081] like Figure 2 , Figures 4-6 As shown, in one embodiment, the second link 220 includes a connector 221. The connector 221 is connected to the pedal 300 for mounting and fixing the pedal 300. The first link 210 is rotatably connected to the connector 221, and the reinforcing member 222 is connected to the connector 221. The first link 210 is located in the first mounting space 2213a and connected to the connector 221, so that a portion of the first link 210 is located inside the first mounting space 2213a. The connector 221 can isolate some foreign objects, which helps to increase the obstruction of foreign objects entering the link assembly 200 and reduce the foreign object ingress into the link assembly 200.

[0082] like Figures 4-7 As shown, in one embodiment, the connector 221 includes a first mounting portion 2211 and a second mounting portion 2212. The first mounting portion 2211 is used to mount the pedal 300. There are at least two second mounting portions 2212, which are spaced apart along the length Y direction of the vehicle. The first connecting rod 210 is rotatably connected to the second mounting portions 2212. The first mounting portion 2211 and the at least two second mounting portions 2212 form a drainage gap 2213. The drainage gap 2213 is used for the discharge of foreign objects inside the connecting rod assembly 200. That is, the drainage gap 2213 provides a channel for the discharge of foreign objects inside the connecting rod assembly 200, avoiding obstruction and interference to the discharge of foreign objects, thereby preventing the accumulation of foreign objects inside the connecting rod assembly 200 and facilitating the discharge of foreign objects. At the same time, the drainage gap 2213 is also a structure for reducing the material of the connector 221, which helps to reduce the weight of the connector 221 and achieve structural lightweighting. Understandably, lightweight structural design helps reduce the driving energy consumption of drive components, thereby lowering the overall energy consumption of the vehicle and improving its range. This is especially important for new energy vehicles, where range is a crucial performance indicator.

[0083] In one embodiment, the reinforcing member 222 is disposed in the sewage discharge gap 2213 along the length Y of the vehicle. The reinforcing member 222 and at least two second mounting portions 2212 surround to form a first mounting space 2213a. The first mounting space 2213a is part of the sewage discharge gap 2213, providing space for the discharge of foreign objects and also helping to reduce the weight of the connecting member 221, thereby achieving a lightweight structure.

[0084] In one embodiment, the surface of the reinforcing member 222 facing the first connecting rod 210 is a first guide surface 2221. The first guide surface 2221 is disposed facing the first connecting rod 210 and is configured to guide the discharge of foreign objects located within the connecting rod assembly 200. This first guide surface 2221 can guide the discharge of foreign objects such as mud, sand, and snow accumulated in the gaps of the connecting rod assembly 200, making it easier for the foreign objects accumulated in the gaps of the connecting rod assembly 200 to fall off naturally, facilitating the discharge of foreign objects, and avoiding problems such as wear, abnormal noise, or even breakage of the connecting rod assembly 200 due to foreign objects remaining in the gaps, thus improving the service life of the connecting rod assembly 200.

[0085] It is worth noting that the orientation in this embodiment includes both faces that are parallel to each other and tilted orientations with a certain angle between the two surfaces.

[0086] Optionally, if each set of pedal devices 1000 includes two sets of linkage assemblies 200 and a drive member 100, the first link 210 of one set of linkage assemblies 200 is connected to the drive member 100, and the first link 210 of the other set of linkage assemblies 200 is not connected to the drive member 100, but can only be rotatably mounted on the vehicle body.

[0087] like Figure 2 and Figure 3 As shown, in one embodiment, when the pedal 300 is in the retracted position, the first guide surface 2221 and the surface of the first connecting rod 210 facing the first guide surface 2221 are parallel to each other. This is beneficial to increase the resistance to foreign objects entering the connecting rod assembly 200 by utilizing the small gap fit of the large area of ​​the surfaces of the first guide surface 2221 and the first connecting rod 210 facing the first guide surface 2221. For example, during vehicle operation, when small particles of dust, stones, or mud enter the gap between the first guide surface 2221 and the first connecting rod 210, since the first connecting rod 210 and the first guide surface 2221 are arranged face to face, it is relatively easy for foreign objects to enter the inlet, but it is difficult for them to continue to enter the connecting rod assembly 200 along the gap between the first connecting rod 210 and the first guide surface 2221. Therefore, by utilizing the parallel properties of the surfaces of the first guide surface 2221 and the first connecting rod 210 facing the first guide surface 2221, the surface between the first guide surface 2221 and the first connecting rod 210 acts as a barrier to prevent foreign objects from entering, thereby improving the effect of blocking foreign objects from entering.

[0088] For example, when the pedal 300 is in the retracted position, the distance between the first connecting rod 210 and the first guide surface 2221 is at its minimum, which can be 2mm-5mm. This distance only allows small particles of dust, stones, or mud to pass through and enter the connecting rod assembly 200. Now, in conjunction with actual vehicle applications, the impact of these three types of foreign matter—small particles of dust, stones, or mud—on the connecting rod assembly 200 is analyzed. First, dust has a relatively small impact on the wear and mechanical properties of the connecting rod assembly 200. Second, stones, being granular, lack adhesive force and are not easily adhered to the inside of the connecting rod assembly 200. Even if they remain inside the connecting rod assembly 200 for a short time when it is in the retracted position, they will fall off during the movement of the connecting rod assembly 200 when it is extended, having a relatively small and only temporary impact on its performance. Furthermore, although mud has a certain adhesion ability and can easily adhere to the gaps inside the connecting rod assembly 200, mud can adhere when it is wet. However, once the mud dries, it is easily detached during acceleration, deceleration, or bumpy driving. It is also relatively easy to loosen and detach when the connecting rod assembly 200 switches from the retracted position to the extended position, due to the increased distance between the first connecting rod 210 and the first guide surface 2221 and the vibration during the movement.

[0089] When the distance between the first connecting rod 210 and the first guide surface 2221 is greater than 5mm, the ability of the connecting rod assembly 200 to block foreign objects will be weakened when it is in the retracted position. When the distance between the first connecting rod 210 and the first guide surface 2221 is less than 2mm, due to machining errors, the small distance can easily lead to interference between parts when machining errors are present. Therefore, a distance of 2mm-5mm between the first connecting rod 210 and the first guide surface 2221 is the preferred range.

[0090] Specifically, the distance between the first connecting rod 210 and the first guide surface 2221 can be 2mm, 3mm, 4mm, 5mm, etc. Of course, it is not limited to this; within the above range, the distance between the first connecting rod 210 and the first guide surface 2221 can be set according to actual needs.

[0091] Please continue reading Figure 2 , Figures 4-6In one embodiment, the first link 210 includes a first body 211 and a first connecting shaft 212. The first body 211 includes a first mounting sleeve 2111, and the first connecting shaft 212 passes through the first mounting sleeve 2111. The first body 211 is rotatably connected to the connector 221 via the first connecting shaft 212. The projections of the first mounting sleeve 2111 and the first guide surface 2221 on the driving surface M1 are at least partially spaced apart, so that there is a gap between the first mounting sleeve 2111 and the first guide surface 2221 facing the driving surface M1, which facilitates the dislodging of foreign objects during driving. Moreover, this gap facing the driving surface M1 is not conducive to the entry of foreign objects, and even if foreign objects enter, they are easy to fall off under the action of gravity.

[0092] In one embodiment, the reinforcing member 222, the first mounting portion 2211, and at least two second mounting portions 2212 enclose a second mounting space 2213b. A second guide surface 2211a is provided on the side of the first mounting portion 2211 facing the second mounting space 2213b. The second guide surface 2211a connects to the plane containing the foot surface of the pedal 300, and the distance between the second guide surface 2211a and the plane containing the foot surface of the pedal 300 gradually increases in the direction away from the pedal 300. When the pedal 300 is unfolded, the second guide surface 2211a provides a guide for the discharge of foreign objects from the foot surface side of the pedal 300, which helps to prevent foreign objects from getting stuck at the corner between the first mounting portion 2211 and the second mounting portion 2212. Simultaneously, the second guide surface 2211a helps to strengthen the connection between the first mounting portion 2211 and the second mounting portion 2212, avoiding mechanical problems such as stress concentration at the connection point when they are connected at right angles, and improving the structural strength of the connector 221.

[0093] like Figure 4 , Figure 6 as well as Figure 7 As shown, in one embodiment, the linkage assembly 200 further includes a third linkage 230, which is rotatably mounted on the vehicle body. A portion of the third linkage 230 is located in the second mounting space 2213b and is rotatably connected to the second mounting portion 2212. Along the width direction X of the vehicle, the two sides of the third linkage 230 are spaced apart from the first mounting portion 2211 and the reinforcing member 222, respectively. This embodiment realizes the multi-functional utilization of the second mounting space 2213b. While satisfying the sewage discharge function, the third linkage 230 is also installed in the second mounting space 2213b, which helps to reduce the volume and size of the linkage assembly 200. Furthermore, the second mounting portions 2212 located on both sides along the length direction Y of the vehicle can also isolate some foreign objects, which helps to increase the obstruction of foreign objects entering the linkage assembly 200 and reduce the foreign object ingress rate of the linkage assembly 200.

[0094] like Figure 6As shown, the third link 230 is further installed in the second mounting space 2213b, so that when the pedal 300 is in the extended or retracted position, the third link 230 can block part of the second mounting space 2213b, thereby reducing the opening area of ​​the second mounting space 2213b when the pedal 300 is in the extended position. This allows foreign objects to be discharged from the second mounting space 2213b, which remains open, and also prevents the opening area from being too large, which could lead to the entry of large-sized foreign objects.

[0095] like Figure 6 , Figure 8 and Figure 9 As shown, in one embodiment, when the pedal 300 is in a position between the extended position and the retracted position, the distance between the opposing surfaces of the first link 210 and the third link 230 is a first distance D1, as... Figure 8 As shown, when the pedal 300 is in the extended position, the distance between the opposing surfaces of the first link 210 and the third link 230 is the second distance D2. Figure 6 As shown, when the pedal 300 is in the retracted position, the distance between the opposing surfaces of the first link 210 and the third link 230 is the third distance D3, as... Figure 9 As shown; the first distance D1 is greater than the second distance D2; that is, when the pedal 300 is in the middle process, the distance between the first link 210 and the third link 230 is greater than the distance when the pedal 300 is in the unfolded position, so that the larger particulate dirt inside can be discharged by the link assembly 200 during the switching between the two positions.

[0096] In one embodiment, the first distance D1 is greater than the third distance D3. That is, when the pedal 300 is in the middle position, the distance between the first link 210 and the third link 230 is greater than the distance when the pedal 300 is in the retracted position. This allows the link assembly 200 to expel larger-sized contaminants during the switching between the two positions, preventing foreign objects from remaining inside the link assembly 200.

[0097] Alternatively, the first distance D1 is greater than the second distance D2, and the first distance D1 is greater than the third distance D3. This size design allows the pedal 300 to be in one of three positions: the deployed position, the retracted position, or the middle position during the switching process. The distance between the first link 210 and the third link 230 is the largest in the middle position during the switching process, so that the link assembly 200 can expel large foreign objects during both the deployment and retraction processes, and prevent foreign objects from being trapped inside the link assembly 200.

[0098] like Figure 9 and Figure 10As shown, in one embodiment, the third link 230 includes a second body 231, a second connecting shaft 232 and a third connecting shaft 233. The second connecting shaft 232 passes through the second body 231, and the second body 231 is rotatably connected to the second mounting part 2212 through the second connecting shaft 232. The second body 231 is rotatably mounted on the vehicle body through the third connecting shaft 233.

[0099] Since the third link 230 is rotatably connected to the second mounting part 2212 via the second connecting shaft 232, and the third link 230 is located in the second mounting space 2213b, the second connecting shaft 232 is also located in the second mounting space 2213b. When the pedal 300 is in the unfolded position, the third link 230 rotates to abut against the first link 210. At this time, the third link 230 covers a portion of the second mounting space 2213b, that is, the third link 230 covers the part of the second mounting space 2213b formed by the second connecting shaft 232, the reinforcing member 222, and the two sets of second mounting parts 2212. This part is named the unfolded closed hole 2213b2. When the pedal 300 is in the unfolded position, the part of the second mounting space 2213b formed by the second connecting shaft 232, the first mounting part 2211, and the two sets of second mounting parts 2212 is in an uncovered state. This part is named the unfolded drain hole 2213b1.

[0100] like Figure 7 , Figure 9 and Figure 10 When the pedal 300 is in the retracted position, the third link 230 rotates to another position abutting against the first link 210. At this time, the third link 230 can close the unfolded drain hole 2213b1. However, the unfolded closing hole 2213b2 is in an open state, and foreign objects can easily enter the link assembly 200 through the unfolded closing hole 2213b2. To solve this problem, the third link 230 includes a blocking part 234. The blocking part 234 is disposed on the side of the second body 231 away from the third link 233. The blocking part 234 is configured to close the second mounting space 2213b enclosed by the third link 230, the first mounting part 2211, and the second mounting part 2212 when the pedal 300 is in the retracted position. Specifically, the blocking part 234 is used to block the unfolded drain hole 2213b1 when the pedal 300 is in the retracted position. Through the blocking part 234, the third link 230 can block the second mounting space 2213b when the pedal 300 is in the retracted position, or at least block part of it, which helps to reduce the entry of foreign objects into the link assembly 200 through the unfolded drain hole 2213b1 when the pedal 300 is in the retracted position.

[0101] Meanwhile, since the third link 230 is rotatable, the blocking part 234 has a blocking effect when the pedal 300 is in the retracted position, and will at least partially block the unfolded drain hole 2213b1 when the third link 230 is rotated to the unfolded position. Therefore, in one embodiment, the side of the second body 231 facing away from the first link 210 is the first side 2311, and the surface of the blocking part 234 facing the first side 2311 is inclined so that when the pedal 300 is in the unfolded position, the distance from the surface of the blocking part 234 facing the first side 2311 to the first side 2311 gradually increases, so that when the third link 230 is in the unfolded position, the inclined surface of the blocking part 234 facing the first side 2311 can play a guiding role, preventing foreign objects from being stuck on the blocking part 234 and unable to be discharged.

[0102] like Figure 9 and Figure 10 In one embodiment, the blocking part 234 has inclined surfaces on both sides along the Y direction, so that when the pedal 300 is in the retracted position, an overflow hole 2213c is formed between the blocking part 234 and the first mounting part 2211. Since the blocking part 234 partially obstructs the unfolded drain hole 2213b1 when the pedal 300 is in the unfolded position, affecting the discharge of foreign matter, the blocking part 234 is provided with an overflow hole 2213c so that foreign matter on both sides of the blocking part 234 along the Y direction can be discharged at the overflow hole 2213c, thereby reducing the obstruction of the unfolded drain hole 2213b1 by the blocking part 234 and improving the drainage effect of the second mounting space 2213b when the pedal 300 is in the unfolded position.

[0103] It is worth noting that when the pedal 300 is in the intermediate position between the extended position and the retracted position, the blocking part 234 is located on the side of the second body 231 facing the driving surface M1, and will not obstruct any part of the second mounting space 2213b, thereby facilitating the discharge of large foreign objects in the intermediate position between the extended position and the retracted position of the pedal 300.

[0104] like Figure 9 and Figure 10 In one embodiment, the pedal device further includes a mounting base 400, with the drive component 100 and the linkage assembly 200 disposed on the mounting base 400 for connection to the vehicle body. The mounting base 400 serves as a carrier for the linkage assembly 200, enabling modular management of the drive mechanism and facilitating assembly and disassembly of the drive mechanism.

[0105] Specifically, during assembly, the pedal 300 can be assembled onto the linkage assembly 200, then the linkage assembly 200 can be assembled onto the mounting base 400, and finally the mounting base 400 can be placed on the vehicle body to complete the assembly. When maintenance or repair is required, the mounting base 400 can be removed from the vehicle body first, and then the linkage assembly 200, drive component 100, and pedal 300 can be inspected and repaired.

[0106] In one embodiment, the mounting base 400 includes a fixing part 410 and a support part 420. The fixing part 410 is used to connect to the vehicle body; the support part 420 is connected to the side of the fixing part 410 away from the vehicle body. There are two sets of support parts 420. In the Y direction, one set of support parts 420 is located on one side of the fixing part 410, and the other set of support parts 420 is located on the other side of the fixing part 410. The connecting rod assembly 200 is connected to the support parts 420 and is located between the two sets of support parts 420. At this time, the two sets of support parts 420 have a shielding function, which can prevent foreign objects from entering the interior of the connecting rod assembly 200 from both sides, which is conducive to maximizing the sealing of external gaps and effectively preventing foreign objects from intruding into the interior of the connecting rod assembly 200.

[0107] Simultaneously, when the pedal 300 is in the extended and retracted positions, a minimum clearance is maintained between the fixing part 410 and the connecting rod assembly 200. This minimum clearance can be 2mm-5mm. This distance only allows small particles of dust, pebbles, or mud to pass through and enter the interior of the connecting rod assembly 200. When the minimum clearance is greater than 5mm, the ability to block foreign objects will be weakened. When the minimum clearance is less than 2mm, due to machining errors, the distance is too small, and interference between parts is likely to occur when these machining errors are combined. Therefore, a minimum clearance between 2mm and 5mm is the preferred range. Specifically, the value of the minimum clearance can be 2mm, 3mm, 4mm, 5mm, etc. Of course, it is not limited to these; within the above range, the value of the minimum clearance can be set according to actual needs.

[0108] In one embodiment, the surface of the support 420 facing the connecting rod assembly 200 is flat, preventing foreign objects such as mud and sand from adhering to the surface. This helps reduce the accumulation of foreign objects on the side of the connecting wall facing the connecting rod assembly 200, improves the ability of the mounting base 400 to prevent the accumulation of foreign objects, and reduces problems such as abnormal noise or failure of the connecting rod assembly 200 caused by foreign objects.

[0109] The gap between the support portion 420 and the connecting rod assembly 200 is 2mm-5mm. This gap allows for a small clearance between the support portion 420 and the connecting rod assembly 200. While avoiding excessive interference between the support portion 420 and the movement of the connecting rod assembly 200, minimizing the gap helps reduce the accumulation of foreign objects on the side of the support portion 420 facing the connecting rod assembly 200. This improves the mounting base 400's ability to prevent foreign object accumulation and reduces problems such as abnormal noise or failure of the connecting rod assembly 200 caused by foreign objects.

[0110] For example, the gap between the side of the support portion 420 facing the link assembly 200 and the link assembly 200 can be 2mm, 3mm, 4mm, or 5mm. In this embodiment, the gap between the side of the support portion 420 facing the link assembly 200 and the link assembly 200 is 3mm.

[0111] When the pedal device includes a drive member 100, two sets of linkage assemblies 200 jointly support a pedal 300, and the drive member 100 is connected to a linkage assembly 200 located near the rear. This linkage assembly 200 is the active linkage assembly 200, and the other linkage assembly 200 is the follower linkage assembly 200. In this case, the first linkage 210 connected to the drive member 100 has a smaller thickness and lower structural strength requirements, and its structure is as follows: Figure 11 As shown. The first connecting rod 210, which is connected to the driving component 100, is subjected to a large force, requiring high structural strength, and the structure is as follows. Figure 12 As shown.

[0112] In one embodiment, to reduce weight, a first weight-reducing groove 2112 is provided on the side of the first connecting rod 210 facing away from the third connecting rod 230, in an area with lower stress. Considering both weight reduction and structural strength, the first connecting rod 210 also includes a first reinforcing rib 214. The first reinforcing rib 214 is located on the side of the first connecting rod 210 facing away from the third connecting rod 230 and is situated within the first weight-reducing groove 2112. The first reinforcing rib 214 is arranged along the extending direction of the first body 211. This approach helps to balance the weight reduction effect of the first connecting rod 210 with maintaining structural strength unaffected by weight reduction.

[0113] Optionally, there are multiple first reinforcing ribs 214, which are arranged parallel to each other along the Y direction and spaced apart to improve the structural reinforcement effect.

[0114] Optionally, the first link 210 further includes a fourth link 213, which is used to connect to the mounting base 400 or to the drive member 100. When the first link 210 is located on the mounting base 400 connected to the drive member 100, the fourth link is connected to the drive member 100. When the first link 210 is located on the mounting base 400 connected to the drive member 100, the fourth link is rotatably connected to the mounting base 400.

[0115] like Figure 11 As shown, the first connecting rod 210 connected to the drive member 100 gradually increases in depth along the direction close to the fourth connecting shaft 213. This creates a slope with a guiding effect in the first weight reduction groove 2112, making it more difficult for foreign objects to accumulate in the shallower location. This reduces the accumulation of foreign objects and provides guidance for the falling off of accumulated foreign objects.

[0116] like Figure 12 As shown, due to the high structural strength requirements of the first connecting rod 210 connected to the drive component 100, the overall wall thickness is increased. Therefore, the first weight-reducing groove 2112 is set along the overall extension direction of the first connecting rod 210, and the first reinforcing rib 214 is set accordingly along the extension direction of the first weight-reducing groove 2112. The depth of the first weight-reducing groove 2112 can be locally set with depth variation on the side away from the fourth connecting shaft 213, and the depth gradually decreases along the direction away from the fourth connecting shaft 213, so as to ensure structural strength while setting a sewage discharge guide surface.

[0117] like Figure 13 As shown, a third weight-reducing groove 2113 is provided on the side of the first connecting rod 210 facing the third connecting rod 230. The third weight-reducing groove 2113 is located close to the first connecting shaft 212, and its depth gradually increases along the direction away from the first connecting shaft 212. The side closer to the first connecting shaft 212 experiences greater stress in the extended position, requiring a larger thickness. Furthermore, since the third weight-reducing groove 2113 faces the driving surface M1 when the connecting rod assembly 200 is in the retracted position, and the first connecting shaft 212 is located below the third weight-reducing groove 2113, the gradual increase in depth along the direction away from the first connecting shaft 212 creates a depth gradient within the third weight-reducing groove 2113, facilitating the guidance of foreign matter discharge when the connecting rod assembly 200 is in the retracted position. Therefore, this structural design effectively balances stress requirements and wastewater discharge requirements.

[0118] like Figure 14 As shown, in one embodiment, the third link 230 further includes a second reinforcing rib 235, which is located on the side of the third link 230 away from the first link 210 and is arranged along the extending direction of the third body. Since the pedal 300, when in the deployed position, experiences a force towards the driving surface M1 under the action of the pedal, the side of the third link 230 away from the first link 210 experiences a certain tensile stress. Therefore, providing the second reinforcing rib 235 on this surface helps to improve the tensile strength of the first link 210, enhance its structural strength, and thus increase its service life.

[0119] Optionally, there are multiple second reinforcing ribs 235, which are parallel and spaced apart along the Y direction to improve the structural reinforcement effect.

[0120] Understandably, the second weight-reducing groove 236 is formed between the multiple second reinforcing ribs 235 to reduce the weight of the third connecting rod 230 and achieve a lightweight effect.

[0121] Furthermore, along the extension direction of the third body, the depth of the second weight reduction groove 236 near both sides of the third body is greater than the depth of the second weight reduction groove 236 near the middle of the first body 211, and the depth gradually changes, thereby forming a slope with a guiding effect in the second weight reduction groove 236. In addition, it is more difficult for foreign objects to accumulate in the shallower position, which can reduce the accumulation of foreign objects and also provide guidance for the accumulation of foreign objects to fall off.

[0122] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0123] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
