Description

Technical Field

[0001] This utility model relates to the field of vehicle parts technology, specifically to a pedal linkage mechanism, a pedal assembly, and a vehicle. Background Technology

[0002] With the development of automotive technology, in order to improve the convenience of getting in and out of the vehicle for drivers and passengers, some models with higher chassis have been equipped with intelligent pedals.

[0003] Currently, in related technologies, intelligent pedals, such as pedal assemblies, mainly include a pedal body and a pedal linkage mechanism. The pedal body is mounted on the vehicle body through the pedal linkage mechanism. A single linkage component of the pedal linkage mechanism typically adopts the following scheme: for example, the linkage assembly includes a linkage body, a pin structure, and two connecting brackets. The connecting brackets have grooves and two through holes. The ends of the pin structure pass through the corresponding through holes on the connecting brackets via shaft fittings. The end of the linkage body is located in the groove and fixedly fitted onto the pin structure. A pre-reserved groove for installing a rubber ring is opened on the inner wall of the shaft fitting. A rubber ring is placed between the inner wall of the shaft fitting and the pin structure. The end of the connecting bracket is sealed by inserting a sealing plug into the through hole, thereby achieving sealing of the pin structure both inside and outside the connecting bracket.

[0004] However, the aforementioned pedal linkage mechanism has a large number and variety of sealing structures that cooperate with the pin structure, which not only increases the assembly difficulty of the pedal linkage mechanism, but also, if the sealing plug at the end of the pin structure becomes loose, foreign objects may enter the linkage assembly from the end of the pin structure, thereby increasing the risk of malfunction of the pedal linkage mechanism. Utility Model Content

[0005] The problem this invention addresses is how to reduce the assembly difficulty and the risk of malfunction of the pedal linkage mechanism.

[0006] To solve the above problems, this utility model provides a pedal linkage mechanism, a pedal assembly, and a vehicle.

[0007] In a first aspect, this utility model provides a pedal linkage mechanism, including a pin, a sealing assembly, two connecting rods, a first connecting frame, and a second connecting frame. The first connecting frame is used to connect to the vehicle chassis. The two ends of one connecting rod are rotatably connected to the first connecting frame and the second connecting frame respectively via the pin. One end of the other connecting rod is rotatably connected to the first connecting frame via the pin or a drive shaft, and the other end of the other connecting rod is rotatably connected to the second connecting frame via the pin. The end of the second connecting frame away from the connecting rod is used to connect to the pedal body.

[0008] Both the first connecting frame and the second connecting frame include two support bodies. At least one of the support bodies has a first groove. The end of the pin is inserted into the first groove of the corresponding support body. There is a preset interval between the two support bodies located at the same end of the connecting rod. The end of the connecting rod is located within the interval and is sleeved on the pin. The sealing component is respectively provided between each support body and the end of the connecting rod.

[0009] Optionally, the sealing assembly includes a bushing and a sealing ring structure. The bushing is embedded between the pin or the drive shaft and the inner wall of the first groove of the corresponding bracket body, and the sealing ring structure is engaged between the end of the connecting rod and the corresponding bracket body.

[0010] Optionally, the bracket body is provided with a first annular groove, the connecting rod is provided with a second annular groove, the sealing assembly includes a first sealing ring, the sealing ring structure includes a first annular connecting part, and the first annular connecting part is inserted into the first annular groove and the second annular groove at both ends along the axial direction of the pin shaft, respectively.

[0011] Optionally, the sealing ring structure further includes an annular protrusion, which is disposed on the inner wall of the first annular connecting portion and is located between the connecting rod and the bracket body.

[0012] Optionally, the bushing includes a second annular connecting portion and an annular limiting portion. The second annular connecting portion is embedded between the pin and the inner wall of the first groove of the corresponding bracket body. The second annular connecting portion is bent and extended at one end along the axial direction of the pin in a direction away from the central axis of the pin to form the annular limiting portion. The annular limiting portion is located between the connecting rod and the bracket body.

[0013] Optionally, a third annular groove is formed on the inner wall of the bushing, the sealing ring structure is embedded in the third annular groove, and the sealing ring structure is sleeved on the pin.

[0014] Optionally, of the two bracket bodies of the first connecting frame, one bracket body is provided with the first groove, and the other bracket body is provided with a through hole, the first groove and the through hole being used for the insertion of the drive shaft.

[0015] Optionally, the two bracket bodies of the second connecting frame are each provided with the first groove, and the two ends of the pin are respectively inserted into the two corresponding first grooves of the second connecting frame.

[0016] Secondly, this utility model provides a pedal assembly, including a pedal body and a pedal linkage mechanism as described above, wherein the pedal body is connected to the vehicle chassis through the pedal linkage mechanism.

[0017] Optionally, the pedal assembly includes a mounting component, a drive assembly, and a plurality of pedal linkage mechanisms, wherein the plurality of pedal linkage mechanisms are spaced apart along the extension direction of the pedal body, and a first connecting frame of the pedal linkage mechanism is connected to the vehicle chassis via the mounting component;

[0018] The drive assembly includes a drive body and a drive shaft. The drive body is used to be mounted on the mounting bracket or the vehicle chassis. The drive shaft passes through the first connecting bracket and is driven to one end of the connecting rod of the pedal linkage mechanism. The drive body is used to drive one end of the connecting rod to rotate through the drive shaft.

[0019] Optionally, the bracket body of the first connecting frame is fitted to the driver body; the end of the bracket body facing the driver body is provided with a first sealing structure, and the end of the driver body facing the bracket body is provided with a second sealing structure, and the first sealing structure is connected to the second sealing structure.

[0020] Thirdly, this utility model provides a vehicle that includes the pedal linkage mechanism as described above, or includes a vehicle chassis and the pedal assembly as described above.

[0021] The beneficial effects of this utility model on the pedal linkage mechanism, pedal assembly, and vehicle are:

[0022] The pedal linkage mechanism may include a pin, a sealing assembly, two connecting rods, a first connecting frame, and a second connecting frame. The mechanism can be configured by fixing the first connecting frame to, for example, the bottom of the vehicle chassis; rotatably connecting one end of one connecting rod to the first connecting frame via a pin; rotatably connecting one end of the other connecting rod to the first connecting frame via a pin or a drive shaft; and rotatably connecting the other ends of both connecting rods to the second connecting frame via pins. The end of the second connecting frame furthest from the connecting rods is used to connect the pedal body. This constitutes a pedal linkage mechanism mounted on the bottom of the vehicle chassis. The drive shaft can drive the other connecting rod to rotate, thereby linking the first connecting rod and the second connecting frame. This allows the pedal body to unfold from the bottom of the vehicle chassis via the second connecting frame to facilitate passenger entry and exit, or to retract the pedal body to the bottom of the vehicle chassis, concealing it under the vehicle. This does not increase the vehicle's lateral dimensions and reduces wind resistance during driving.

[0023] Furthermore, the first and second connecting frames can be divided into two support bodies. The end of the pin is inserted into the first groove of the two support bodies of the corresponding connecting frame. In other words, the end of the pin does not penetrate the support body. The end of the pin is sealed by the side wall of the support body corresponding to the first groove. This eliminates the need to install the sealing plugs of the aforementioned related technology at both ends of the pin. Therefore, a sealing component can be set only between the end of the connecting rod and the corresponding support body. The sealing component can prevent foreign objects from entering the first and second connecting frames and the pin from the connection between the end of the connecting rod and the support body. This not only effectively reduces the number of sealing structures involved in the pedal linkage mechanism and reduces the assembly difficulty of the pedal linkage mechanism, but also seals the pin, thereby reducing the risk of failure of the pedal linkage mechanism.

[0042] In related technologies, with the development of automotive technology, in order to improve the convenience of getting in and out of the vehicle for drivers and passengers, some models with high chassis have been equipped with intelligent pedals.

[0043] Currently, in related technologies, intelligent pedals, such as pedal assemblies, mainly include a pedal body and a pedal linkage mechanism. The pedal body is mounted on the vehicle chassis via the pedal linkage mechanism. The individual linkage components of the pedal linkage mechanism typically employ the following scheme, combined with... Figure 1 As shown, for example, the connecting rod assembly includes a connecting rod body 3', a pin structure 1', and two connecting brackets 4'. The connecting brackets 4' are provided with grooves 41' and two through holes. The ends of the pin structure 1' are respectively inserted through the corresponding through holes on the connecting brackets 4' via shaft fittings 22'. The ends of the connecting rod body 3' are located in the grooves 41' and are fixedly sleeved on the pin structure 1'. The inner wall of the shaft fittings 22' has a reserved groove for installing rubber rings 21'. A rubber ring 21' is provided between the inner wall of the shaft fittings 22' and the pin structure 1'. The ends of the connecting brackets 4' are sealed by inserting sealing plugs 23' into the through holes, thereby achieving sealing operations of the pin structure 1' inside and outside the connecting brackets 4'.

[0044] However, the number and variety of sealing structures that cooperate with the pin structure 1' in the above-mentioned pedal linkage mechanism are large, which not only increases the assembly difficulty of the pedal linkage mechanism, but also, if the sealing plug 23' at the end of the pin structure 1' becomes loose, foreign objects may enter the linkage assembly from the end of the pin structure 1', which increases the risk of failure of the pedal linkage mechanism.

[0045] To address the problems existing in the aforementioned related technologies, this embodiment provides a pedal linkage mechanism, a pedal assembly, and a vehicle.

[0046] like Figure 2 and Figure 3 As shown in the figure, an embodiment of the present invention provides a pedal linkage mechanism 100, including a pin 1, a sealing assembly 2, two connecting rods 3, a first connecting frame 4, and a second connecting frame 5. The first connecting frame 4 is used to connect to the vehicle chassis. The two ends of one connecting rod 3 are rotatably connected to the first connecting frame 4 and the second connecting frame 5 respectively through the pin 1. One end of the other connecting rod 3 is rotatably connected to the first connecting frame 4 through the pin 1 or a drive shaft 302, and the other end of the other connecting rod 3 is rotatably connected to the second connecting frame 5 through the pin 1. The end of the second connecting frame 5 away from the connecting rod 3 is used to connect to the pedal body 200.

[0047] Both the first connecting frame 4 and the second connecting frame 5 include two support bodies 41. At least one of the support bodies 41 has a first groove 411. The end of the pin 1 is inserted into the first groove 411 of the corresponding support body 41. There is a preset interval between the two support bodies 41 located at the same end of the connecting rod 3. The end of the connecting rod 3 is located within the interval and is sleeved on the pin 1. The sealing component 2 is respectively provided between each support body 41 and the end of the connecting rod 3.

[0048] Specifically, the first connecting frame 4 is typically fixed to the bottom of the vehicle chassis using fasteners such as bolts. Furthermore, to improve the load-bearing capacity of the pedal body 200 and ensure force balance, the pedal assembly may be equipped with multiple, for example, two pedal linkage mechanisms 100 (see...). Figure 6 and Figure 7 As shown in the diagram, in one pedal linkage mechanism 100, the two support bodies 41 of the first connecting frame 4 are rotatably connected to the end of one of the connecting rods 3 via a drive shaft 302. In this case, the pedal linkage mechanism 100 is an active end linkage mechanism, and the first connecting frame 4 in the active end linkage mechanism can be an active support, and the second connecting frame 5 in the active end linkage mechanism can be an active base frame. In the other pedal linkage mechanism, the two support bodies 41 of the first connecting frame 4 and the end of one connecting rod 3 are rotatably connected via a pin 1. In this case, the pedal linkage mechanism 100 is a follower end linkage mechanism, and the first connecting frame 4 in the follower end linkage mechanism can be a driven support, and the second connecting frame 5 in the follower end linkage mechanism can be a follower base frame.

[0049] Since the end of the connecting rod 3 is sleeved on the pin 1 or the drive shaft 302, the end of the connecting rod 3 has a sleeve hole. The connecting rod 3 can be a rod-shaped structure with sleeve holes at both ends, or a plate-shaped structure or a block-shaped structure with sleeve holes at both ends.

[0050] The first groove 411 can provide installation space for the end of the pin 1 or the drive shaft 302. The first groove 411 can be a cylindrical groove. Therefore, the inner diameter of the first groove 411 used to install the pin 1 is greater than or equal to the outer diameter of the pin 1, and the inner diameter of the first groove 411 used to install the drive shaft 302 is greater than or equal to the outer diameter of the drive shaft 302.

[0051] The interval between the two support bodies 41 in each connecting frame is greater than or equal to the end dimension of the connecting rod 3, so that the end of the connecting rod 3 can be inserted into the interval.

[0052] Among them, combined Figure 2 , Figure 3 , Figure 6 and Figure 7As shown, the active-end linkage mechanism can adopt the following structural configuration. For example, the active-end linkage mechanism includes a first connecting frame 4, two connecting rods 3, three pins 1, a drive shaft 302, and the first connecting frame 4. Specifically, the two support bodies 41 of the first connecting frame 4 (active support) in the active-end linkage mechanism can be directly fixed to the vehicle chassis, or fixed to the vehicle chassis via mounting parts 400. One pin 1 and the drive shaft 302 are respectively passed through the two support bodies 41 of the first connecting frame 4. One end of the two connecting rods 3 on the same side can be respectively interference-fitted with one of the pins 1 and the corresponding drive shaft 302. The other two pins 1 can be respectively passed through the two support bodies 41 of the second connecting frame 5. The other end of the two connecting rods 3 on the same side can be respectively interference-fitted with the two corresponding pins 1. The two support bodies 41 of the second connecting frame 5 (active base frame) are also fixedly connected to the pedal body 200. The drive shaft 302 can be a component of the pedal linkage mechanism or an assembly component of the driver assembly 300.

[0053] Combination Figure 2 , Figure 3 , Figure 8 and Figure 9 As shown, the follower-end linkage mechanism can adopt the following structural method. For example, the follower-end linkage mechanism includes a first connecting frame 4, two connecting rods 3, four pins 1, and the first connecting frame 4. Specifically, the two support bodies 41 of the first connecting frame 4 (follower bracket) in the follower-end linkage mechanism can be directly fixed to the vehicle chassis, or fixed to the vehicle chassis through the mounting part 400. The two pins 1 are respectively passed through the two support bodies 41 of the first connecting frame 4, and one end of the two connecting rods 3 on the same side can be respectively interference-fitted with the corresponding two pins 1. The other two pins 1 can be respectively passed through the two support bodies 41 of the second connecting frame 5, and the other end of the two connecting rods 3 on the same side can be respectively interference-fitted with the corresponding two pins 1. The two support bodies 41 of the second connecting frame 5 (follower base frame) are also fixedly connected to the pedal body 200.

[0054] When the drive shaft 302 drives another link 3 in the active end linkage mechanism to rotate, the other link 3 drives the other links 3 and the second connecting frame 5 in the active end linkage mechanism to move together, and the two links 3 and the second connecting frame 5 in the follower end linkage mechanism can move together under the driving action of the pedal body 200.

[0055] In this embodiment, the pedal linkage mechanism 100 may include a pin 1, a sealing assembly 2, two connecting rods 3, a first connecting frame 4, and a second connecting frame 5. The first connecting frame 4 can be fixed to, for example, the bottom of the vehicle chassis. One end of one connecting rod 3 is rotatably connected to the first connecting frame 4 via the pin 1, and one end of the other connecting rod 3 is rotatably connected to the first connecting frame 4 via the pin 1 or a drive shaft 302. The other ends of the two connecting rods 3 are respectively rotatably connected to the second connecting frame 5 via the pin 1. The end of the second connecting frame 5 away from the connecting rod 3 is used to connect the pedal body 200, thereby forming a pedal linkage mechanism 100 installed at the bottom of the vehicle chassis. The drive shaft 302 can drive another link 3 to rotate, thereby driving the link 3 and the second connecting frame 5 to move together. This allows the second connecting frame 5 to extend the pedal body 200 from the bottom of the vehicle chassis to facilitate passengers getting in and out of the vehicle, or to retract the pedal body 200 to the bottom of the vehicle chassis so that the pedal body 200 is hidden under the vehicle, thus not increasing the size of the vehicle in the left and right directions and reducing wind resistance during vehicle operation.

[0056] Furthermore, the first connecting frame 4 and the second connecting frame 5 can be divided into two support bodies 41. The end of the pin 1 is inserted into the first groove 411 of the two support bodies 41 of the corresponding connecting frame. In other words, the end of the pin 1 does not penetrate the support body 41, so that the end of the pin 1 is sealed by the side wall of the support body 41 corresponding to the first groove 411. This eliminates the need to install the sealing plugs of the above-mentioned related technology at both ends of the pin 1. Therefore, the sealing component 2 can be set only between the end of the connecting rod 3 and the corresponding support body 41. The sealing component 2 can prevent foreign objects from entering the interior between the first connecting frame 4 and the second connecting frame 4 and the pin 1 from the connection between the end of the connecting rod 3 and the support body 41. This not only effectively reduces the number of sealing structures involved in the pedal linkage mechanism 100 and reduces the assembly difficulty of the pedal linkage mechanism 100, but also seals the pin 1, thereby reducing the risk of failure of the pedal linkage mechanism 100.

[0057] Optionally, combined Figure 3 , Figure 4 , Figure 9 and Figure 10 As shown, the sealing assembly 2 includes a bushing 22 and a sealing ring structure 21. The bushing 22 is embedded between the pin 1 or the drive shaft 302 and the inner wall of the first groove 411 of the corresponding bracket body 41. The sealing ring structure 21 is inserted between the end of the connecting rod 3 and the corresponding bracket body 41.

[0058] Specifically, in combination Figure 4 and Figure 10As shown, the bushing 22 can be sleeved on the outside of the pin 1 or the drive shaft 302, and at least a portion of the bushing 22 is located in the first groove 411 of the bracket body 41. The bushing 22 can be a tubular bushing 22 made of a metal material such as copper alloy. The bushing 22 can reduce the friction of the pin 1 or the drive shaft 302 rotating in the first groove 411 of the bracket body 41, so that the pin 1 or the drive shaft 302 rotates more smoothly in the first groove 411.

[0059] A sealing ring structure 21 is inserted between the end of each bracket body 41 of the first connecting frame 4 (or the second connecting frame 5) and the end of the connecting rod 3. This effectively prevents foreign objects from entering the pin 1 from the connection between the end of the bracket body 41 and the end of the connecting rod 3, thereby reducing the risk of failure of the pedal linkage mechanism 100 and extending its service life.

[0060] Optionally, combined Figure 4 and Figure 10 As shown, the bracket body 41 is provided with a first annular groove, the connecting rod 3 is provided with a second annular groove, and the sealing ring structure 21 includes a first annular connecting part 211, which is inserted into the first annular groove and the second annular groove at both ends along the axial direction of the pin 1, respectively.

[0061] Specifically, the positions of the first annular groove and the second annular groove correspond to each other; since the sealing ring structure 21 can be sleeved on the outside of the pin 1, and the sealing ring structure 21 includes the first annular connecting part 211, the first annular connecting part 211 can be inserted into the first annular groove and the second annular groove respectively along both ends of the pin 1.

[0062] In this optional embodiment, by opening a first annular groove on the bracket body 41 and a second annular groove at the end of the connecting rod 3, the axial ends of the first annular connecting part 211 are respectively inserted into the corresponding first annular groove and second annular groove. Therefore, the first annular groove and the second annular groove can ensure the installation stability of the first annular connecting part 211 in the sealing ring structure 21.

[0063] Optionally, combined Figure 4 and Figure 10 As shown, the sealing ring structure 21 also includes an annular protrusion 212, which is disposed on the inner wall of the first annular connecting portion 211 and is located between the connecting rod 3 and the bracket body 41.

[0064] Specifically, the annular protrusion 212 can be disposed on the inner wall of the first annular connecting part 211, wherein the two can be an integral structure, thereby ensuring the structural integrity of the sealing ring structure 21 and correspondingly extending its service life.

[0065] The annular protrusion 212 can be located between the end of the connecting rod 3 and the support body 41.

[0066] In this optional embodiment, since a sealing ring structure 21 is formed between each support body 41 of the first connecting frame 4 (or the second connecting frame 5) and the end of the connecting rod 3, and the end of the connecting rod 3 is fixedly sleeved outside the pin 1, the end of the connecting rod 3 can be connected to the pin 1 as an integral structure. The axial ends of the first annular connecting portion 211 in each sealing ring structure 21 are respectively inserted into the first annular groove of the support body 41 and the second annular groove of the connecting rod 3. Furthermore, the annular protrusion 212 of the sealing ring structure 21 is located between the end of the connecting rod 3 and the support body 41. In this way, the dual function of the first annular connecting part 211 and the annular protrusion 212 in the sealing ring structure 21 can not only improve the sealing effect between the connecting rod 3 and the bracket body 41, but also limit the pin 1 and the bracket body 41 fixedly sleeved outside the pin 1 in the axial direction of the pin 1, so as to improve the rotational smoothness of the connecting rod 3 and the pin 1 relative to the bracket body 41. In addition, the sealing ring structure 21 can also reduce the rotational noise between the pin 1 and the bracket body 41, thereby improving the sound perception comfort of the vehicle.

[0067] Optionally, combined Figure 4 and Figure 10 As shown, the bushing 22 includes a second annular connecting portion 221 and an annular limiting portion 222. The second annular connecting portion 221 is embedded between the pin 1 and the inner wall of the first groove 411 of the corresponding bracket body 41. The second annular connecting portion 221 is bent and extended at one end along the axial direction of the pin 1 in a direction away from the central axis of the pin 1 to form the annular limiting portion 222. The annular limiting portion 222 is located between the connecting rod 3 and the bracket body 41.

[0068] Specifically, the second annular connecting portion 221 can be a cylindrical structure. One axial end of the second annular connecting portion 221 is bent and extended in a direction away from the central axis of the pin 1 (or towards the outside of the second annular connecting portion 221) to form an annular limiting portion 222. The outer diameter of the annular limiting portion 222 is larger than the outer diameter of the second annular connecting portion 221. The annular limiting portion 222 and the second annular connecting portion 221 can be an integral structure, thereby ensuring the structural integrity and mechanical strength of the bushing 22 and extending its service life accordingly.

[0069] In this optional embodiment, since the second annular connecting portion 221 is embedded between the pin 1 and the inner wall of the first groove 411 of the corresponding bracket body 41, the rotational friction of the end of the pin 1 in the first groove 411 of the corresponding bracket body 41 can be reduced by the second annular connecting portion 221, thereby ensuring the rotational smoothness of the end of the pin 1 relative to the first groove 411 of the bracket body 41; furthermore, the annular limiting portion 222 of the bushing 22 is located between the end of the connecting rod 3 and the bracket body 41, so that the annular limiting portion 222, the first annular connecting portion 211 in the sealing ring structure 21 and the annular protrusion 212 further limit the pin 1 and the bracket body 41 fixedly sleeved outside the pin 1 in the axial direction of the pin 1, thereby further improving the rotational smoothness of the connecting rod 3 and the pin 1 relative to the bracket body 41.

[0070] Unlike the installation method of the bushing 22 and the sealing ring structure 21 in the above embodiments, in this embodiment, the sealing ring structure 21 can be located inside the bushing 22. Specifically, in combination with... Figure 11 and Figure 12 As shown, the inner wall of the bushing 22 has a third annular groove, the sealing ring structure 21 is embedded in the third annular groove, and the sealing ring structure 21 is sleeved on the pin 1.

[0071] Specifically, the sealing ring structure 21 can be installed on the bushing 22 in the following way: for example, a third annular groove can be opened on the inner wall of the bushing 22, the sealing ring structure 21 is fixedly sleeved on the outside of the pin 1, and the sealing ring structure 21 is located in the third annular groove of the bushing 22. Therefore, the bushing 22 with the sealing ring structure 21 installed inside can be embedded between the inner wall of the first groove 411 of the bracket body 41 and the pin 1, which can also play a sealing role between the bracket body 41 and the end of the connecting rod 3. In addition, the third annular groove of the bushing 22 can also play a certain limiting role for the sealing ring structure 21 to ensure the installation stability of the sealing ring structure 21.

Figure 3 As shown), the sealing assembly 2 is used to seal the connection between the bracket body 41 and the end of the connecting rod 3 to prevent foreign objects from entering the pin 1 inside the first connecting frame 4 from the connection between the two.

[0076] Optionally, combined Figure 8 , Figure 9 and Figure 10 As shown, the two bracket bodies 41 of the second connecting frame 5 are provided with the first groove 411, and the two ends of the pin 1 are respectively inserted into the two corresponding first grooves 411 of the second connecting frame 5.

Figure 9 and Figure 10 As shown), the two ends of a pin 1 are respectively located in the first groove 411 corresponding to the two bracket bodies 41.

[0079] A sealing assembly 2 can be provided between the end of each support body 41 in the first connecting frame 4 (and the second connecting frame 5) and the end of the connecting rod 3 in the follower-end linkage mechanism (see...).

[0080] This utility model provides a pedal assembly, including a pedal body 200 and a pedal linkage mechanism 100 as described in the above embodiment. The pedal body 200 is connected to the vehicle chassis through the pedal linkage mechanism 100.

[0081] The pedal assembly of this embodiment has the same beneficial effects over the prior art as the pedal linkage mechanism 100 described above, and will not be repeated here.

[0082] Optionally, combined Figure 2 , Figure 6 and Figure 7 As shown, the pedal assembly includes a mounting member 400, a drive assembly 300, and a plurality of pedal linkage mechanisms 100. The plurality of pedal linkage mechanisms 100 are spaced apart along the extension direction of the pedal body 200. The first connecting frame 4 of the pedal linkage mechanism 100 is connected to the vehicle chassis via the mounting member 400.

[0083] The drive assembly 300 includes a drive body 301 and a drive shaft 302. The drive body 301 is used to be mounted on the mounting member 400 or the vehicle chassis. The drive shaft 302 passes through the first connecting frame 4 and is driven to connect one end of the connecting rod 3 of the pedal linkage mechanism 100. The drive body 301 is used to drive one end of the connecting rod 3 to rotate through the drive shaft 302.

[0084] Specifically, the pedal assembly includes a mounting component 400, a driver assembly 300, and multiple pedal linkage mechanisms 100. The mounting component 400 can be fixedly connected to the vehicle chassis and can be a sheet metal structure. The driver assembly 300 can be a motor or a hydraulic cylinder, etc. When the driver assembly 300 is a motor, the drive shaft 302 can be the motor shaft of the motor, and the driver body 301 can be the sum of all other components in the motor except for the motor shaft. The pedal assembly can be an electric side pedal. When the driver assembly 300 is a hydraulic cylinder, the drive shaft 302 is connected to the output end of the hydraulic cylinder. The hydraulic cylinder performs telescopic movements to drive one of the linkages 3 to rotate, thereby driving the other linkages 3 of the pedal linkage mechanism 100 to move together, so as to realize the unfolding and retraction of the pedal body 200.

[0085] The extension direction of the pedal body 200 can be the length direction of the pedal body 200. If the pedal assembly includes two or more pedal linkage mechanisms 100, each second connecting frame 5 of the multiple pedal linkage mechanisms 100 arranged at intervals can be connected and fixed to the pedal body 200. Each first connecting frame 4 of the multiple pedal linkage mechanisms 100 arranged at intervals can be connected to the vehicle chassis through the mounting member 400, thereby improving the stability of the pedal body 200 installed on the vehicle chassis.

[0086] If the pedal assembly includes a pedal linkage mechanism 100, the second connecting frame 5 in the pedal linkage mechanism 100 can be connected to the middle position of the pedal body 200. The first connecting frame 4 in the pedal linkage mechanism 100 can be connected to the vehicle chassis through the mounting part 400, or the pedal body 200 can be installed on the vehicle chassis.

[0087] Combination Figure 5 As shown, the bracket body 41 of the first connecting frame 4 is fitted to the driver body 301; the bracket body 41 is provided with a first sealing structure 101 at one end facing the driver body 301, and the driver body 301 is provided with a second sealing structure 102 at one end facing the bracket body 41, and the first sealing structure 101 and the second sealing structure 102 are connected.

[0088] Specifically, the first sealing structure 101 may be made of the same material as the bracket body 41, and the second sealing structure 102 may be made of the same material as the housing of the driver body 301.

[0089] The first sealing structure 101 and the second sealing structure 102 can be connected in the following manner, for example, by plugging them together. Specifically, the first sealing structure 101 is an annular protrusion structure disposed at the end of the bracket body 41, and the second sealing structure 102 is an annular groove structure disposed at the end of the driver body 301. The first sealing structure 101 is inserted into the second sealing structure 102 (see...). Figure 5 As shown), this allows for a sealing effect at the connection between the bracket body 41 and the housing of the driver body 301.

[0090] For example, the first sealing structure 101 and the second sealing structure 102 are connected by a sleeve. Specifically, the first sealing structure 101 is a first annular sleeve disposed at the end of the bracket body 41, and the second sealing structure 102 is a second annular sleeve disposed at the end of the housing of the driver body 301. The inner diameter of the first annular sleeve matches the outer diameter of the second annular sleeve, so the first annular sleeve can be sleeved on the outside of the second annular sleeve; or, the outer diameter of the first annular sleeve matches the inner diameter of the second annular sleeve, so the second annular sleeve can be sleeved on the outside of the first annular sleeve, thereby achieving the sealing effect at the connection between the bracket body 41 and the housing of the driver body 301.

[0091] The drive shaft 302 can be located inside the drive body 301; the housing of the drive body 301 and the bracket body 41 in the first connecting frame 4 are arranged along the axial direction of the drive shaft 302, and the housing of the drive body 301 and the adjacent ends of the bracket body 41 are fitted together. In other words, there is no gap or a very small gap between the drive body 301 and the bracket body 41 to ensure the sealing effect of the drive shaft 302 at the connection between the housing of the drive body 301 and the bracket body 41; furthermore, the first sealing structure 101 provided on the bracket body 41 is connected to the second sealing structure 102 provided on the drive body 301, thereby further improving the sealing effect at the connection between the housing of the drive body 301 and the bracket body 41.

[0092] Furthermore, the beneficial effects of the side pedal assembly in this embodiment compared to the prior art are the same as those of the side pedal linkage 3 mechanism described above, and will not be repeated here.

[0093] The present invention provides a vehicle including the pedal linkage mechanism 100 as described above, or including a vehicle chassis and the pedal assembly as described above.

[0094] Specifically, the pedal linkage mechanism 100 in the pedal assembly can be mounted on the vehicle chassis via the mounting piece 400.

[0095] The advantages of the vehicle in this embodiment over the prior art are the same as those of the pedal linkage mechanism or pedal assembly described above, and will not be repeated here.

[0096] Although the present invention has been disclosed above, its protection scope is not limited thereto. Those skilled in the art can make various changes and modifications without departing from the spirit and scope of the present invention, and all such changes and modifications will fall within the protection scope of the present invention.
