[0004] However, an engine muffler exhaust pipe is provided on one side of the driving motor in the electric telescopic pedal, and the engine muffler exhaust pipe generates heat radiation during operation. The driving motor is often affected by the heat radiation of the muffler exhaust pipe, causing the electric telescopic pedal to fail. Utility Model Content

[0005] The present application provides a driving mechanism, a pedal mechanism and a vehicle to solve the problem that the driving motor is easily affected by the heat radiation of the muffler exhaust pipe. The technical solution of the present application is as follows:

[0006] According to a first aspect of the present application, a driving mechanism is provided for driving a pedal of a vehicle, comprising a mounting bracket, a driving motor, a transmission mechanism and a heat insulating member. The driving motor is arranged on the mounting bracket. The transmission mechanism is connected to the driving motor and is used to connect to the pedal. The heat insulating member is mounted on the mounting bracket, and the heat insulating member partially surrounds the driving motor.

[0007] According to the above technical means, the present application can realize the extension and retraction of the driving mechanism by driving the transmission mechanism through the driving motor arranged on the mounting bracket. The heat insulation member installed on the mounting bracket isolates the external heat radiation, so that the driving motor part surrounded by the heat insulation member is not affected by the heat radiation, thereby ensuring the normal operation of the driving mechanism.

[0008] In a possible embodiment, the above-mentioned mounting bracket includes a mounting base plate and a first mounting side plate. The first mounting side plate is arranged on the mounting base plate. The drive motor is arranged on one side of the first mounting side plate and is connected to the first mounting side plate. The thermal insulation member includes a first thermal insulation member and a second thermal insulation member. The first thermal insulation member is located on a side of the first mounting side plate close to the drive motor and is connected to the first mounting side plate. The first thermal insulation member and the drive motor are arranged side by side in a direction parallel to the first mounting side plate, a part of the first thermal insulation member is arranged opposite to the drive motor, and the first thermal insulation member partially surrounds the drive motor.

[0011] According to the above technical means, the present application can arrange the first heat insulation board and the drive motor at a relative interval, so that the drive motor will not be against the first heat insulation board, but there is no relatively fixed connection between them, so that a large number of small collisions will occur between the drive motor and the first heat insulation board, and these external force collisions will cause the drive motor to fail. In addition, the first connecting plate transforms the first heat insulation member and the first mounting side plate into surface contact, and the larger contact area makes the pressure distribution more uniform, which can adapt to more connection methods and improve the stability of the structure.

[0012] In a possible implementation, the first heat insulation board has an arc-shaped edge, and the axial direction of the first heat insulation board is perpendicular to the first installation side plate.

[0013] According to the above technical means, the present application can make the shape of the first heat insulation board fit the drive motor as much as possible, so that the first heat insulation board can reduce the space occupied as much as possible under the premise of protecting the drive motor. At the same time, the arc edge is relatively smoother and has a better effect of reflecting heat radiation.

[0014] In a possible implementation, the first heat insulating member further includes a fourth connecting plate. The fourth connecting plate is located on a side of the first heat insulating plate close to the mounting base plate and connected to the first heat insulating plate. The fourth connecting plate is arranged opposite to the second connecting plate and is located on a side of the second connecting plate away from the drive motor and connected to the second connecting plate.

[0015] According to the above technical means, the present application can convert the contact between the first thermal insulation member and the second thermal insulation member into surface contact, thereby improving the diversity and stability of the connection method.

The second connecting plate and the mounting base plate are connected by the first fastener.

[0017] According to the above technical means, the present application can realize the detachable connection between the second heat insulating member and the mounting bracket through the first fastener. In this connection mode, force transmission between them can be realized.

[0018] In a possible implementation, the driving mechanism further includes a second fastener. The second fastener penetrates the third connecting plate and the first connecting plate and is connected to the third connecting plate and the first connecting plate. The third connecting plate and the first connecting plate are connected via the second fastener.

[0019] According to the above technical means, the second heat insulating member and the first heat insulating member are detachably connected by the second fastener, wherein force transmission between them can be achieved by this connection method.

[0020] In a possible implementation, the driving mechanism further includes a third fastener, the third fastener passes through the fourth connecting plate and the second connecting plate, and is connected to the second connecting plate and the fourth connecting plate, and the second connecting plate and the fourth connecting plate are connected via the third fastener.

[0021] According to the above means, the present application can achieve a detachable connection between the first thermal insulation component and the second thermal insulation component through a third fastener.

[0022] In a possible implementation manner, the first thermal insulation member is made of metal aluminum material.

[0050] In order to enable ordinary persons in the art to better understand the technical solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the accompanying drawings.

[0051] It should be noted that the terms "first", "second", etc. in the specification and claims of the present application and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the data used in this way can be interchangeable where appropriate, so that the embodiments of the present application described herein can be implemented in an order other than those illustrated or described herein. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present application. On the contrary, they are merely examples of devices and methods consistent with some aspects of the present application as detailed in the attached claims.

[0052] As consumers' demands for vehicle comfort and convenience continue to increase, some high-chassis vehicles have high thresholds, which may make it difficult for the elderly, children or people with physical disabilities to get on and off the vehicle. Therefore, providing passengers with a stable pedal can reduce the difficulty of getting on and off the vehicle and improve comfort and convenience. Compared with fixed pedals, electric telescopic pedals can be automatically retracted when not in use, which will not affect the side lines of the vehicle and maintain the streamlined appearance and overall beauty of the vehicle. And when retracted, it does not take up space and will not reduce the minimum ground clearance of the vehicle, thereby not affecting the vehicle's passing performance under complex road conditions. When the pedal is extended, it can also increase the luxury of the vehicle. Therefore, electric telescopic pedals have become an important configuration option when purchasing a vehicle.

[0053] However, since the electric telescopic pedal is arranged on the vehicle chassis, and there are engine muffler parts on the vehicle chassis, and the exhaust pipe of the engine muffler has a high temperature during operation, it is very easy to generate heat radiation to the surrounding structures. Due to the influence of heat radiation, the electric telescopic pedal often fails after a period of use.

[0054] To solve the problem of failure of the electric telescopic pedal due to heat radiation from the exhaust pipe of the engine muffler. The embodiment of the present application provides a vehicle, which can be an electric vehicle, a hybrid vehicle, a solar vehicle, etc. The specific type of the vehicle is not specifically limited here. In order to realize the basic functions of the car, the vehicle may include components such as a body, a chassis, a power system, and an electrical system.

[0055] The vehicle body may include a vehicle frame, vehicle doors, and vehicle windows. The vehicle frame may form the overall shape of the vehicle exterior and form a seating space for accommodating passengers. The vehicle frame may also include a threshold located below the vehicle door. The vehicle door may be rotatably connected to the vehicle frame and may open or close the interior passenger space. The vehicle window may be installed on the vehicle door or the vehicle frame to facilitate passengers to observe the external environment.

[0056] The chassis is located below the door sill. The chassis may include components such as the transmission system and the drive system. The drive system can drive the wheels to rotate. Depending on the drive mode of the drive system, the drive system can be divided into front-wheel drive, rear-wheel drive and four-wheel drive arrangements. The transmission system can transmit the power generated by the engine to the wheels.

[0057] The power system can provide power for the vehicle so that the vehicle can complete basic driving functions. Depending on the type of vehicle, the composition of the power system is also different. Exemplarily, when the vehicle is an electric vehicle, the power system may include an electric motor.

[0058] In order to power electrical components such as motors, the vehicle provided in the embodiments of the present application further includes a battery system. The battery system may include a battery pack, which may be used to provide electrical energy. The battery pack may be electrically connected to the electrical components of the vehicle. In this way, the electrical energy of the battery pack may be transferred to the electrical components of the vehicle for powering.

[0059] Among them, Figure 1 As shown, Figure 1 A partial structural diagram of a vehicle 1000 provided in an embodiment of the present application. The vehicle 1000 includes a pedal mechanism 1, a door sill 2, and an exhaust pipe 3. Exemplarily, the pedal mechanism 1 is installed at the door sill 2 of the vehicle 1000 and is arranged side by side with the exhaust pipe 3.

[0060] The door sill 2 provides a mounting position for the pedal mechanism 1 so that the pedal mechanism 1 can be fixed on the body of the vehicle 1000. In addition, since the pedal mechanism 1 and the exhaust pipe 3 are arranged side by side, the pedal mechanism 1 is often affected by the heat radiation of the exhaust pipe 3 and fails.

[0061] For example, Figure 2 As shown, Figure 2 The schematic diagram of a part of the structure of a vehicle 1000 provided in an embodiment of the present application. The pedal mechanism 1 is installed below the door sill 2 and arranged side by side with the exhaust pipe 3. Figure 3 As shown, Figure 3 This is a partial structural diagram of a vehicle 1000 provided in an embodiment of the present application, in which a pedal mechanism 1 is installed below a door sill 2 through a plurality of connecting members 4. Exemplarily, the connecting members 4 are bolts.

[0062] like Figure 4 As shown, Figure 4 This is a structural schematic diagram of the retracted and deployed states of a pedal mechanism 1 provided in an embodiment of the present application. The pedal mechanism 1 includes a driving mechanism 11 and a pedal 12 .

[0063] The driving mechanism 11 is connected to the pedal 12, and the pedal 12 is extended and retracted by the extension of the driving mechanism 11. Figure 5 As shown, Figure 5 This is a schematic diagram of the structure of a pedal mechanism 1 in an expanded state provided in an embodiment of the present application, in which a pedal 12 is extended to provide support when the driver or passenger needs to get on or off the vehicle. Figure 6 As shown, Figure 6 This is a structural schematic diagram of a pedal mechanism 1 in a retracted state provided in an embodiment of the present application. When there is no need for the driver or passengers to get on or off the vehicle, the pedal 12 is retracted to reduce space occupation.

[0064] In some embodiments, the pedal mechanism 1 further includes a driven mechanism 13 for balancing the force applied to the pedal 12 together with the driving mechanism 11 .

[0065] like Figure 7 As shown, Figure 7 The schematic diagram of the structure of a driving mechanism 11 provided in an embodiment of the present application is as follows. The driving mechanism 11 comprises a mounting bracket 111 , a driving motor 112 and a transmission mechanism 113 .

[0066] The driving motor 112 is disposed on the mounting bracket 111 , and the mounting bracket 111 provides a mounting position for the driving motor 112 , so that the mounting bracket 111 and the driving motor 112 can be connected as a whole.

[0067] The transmission mechanism 113 is connected to the driving motor 112 and is used to communicate with the pedal 12 ( Figure 6 ) connection. The driving motor 112 can drive the transmission mechanism 113 to move by connecting the transmission mechanism 113 to the driving motor 112, thereby realizing the extension and retraction of the driving mechanism 11. The pedal 12 ( Figure 6 ) extension and retraction. The purpose of the above connection is to fix the relative positions of the components so that the force transmission of the drive mechanism 11 can proceed smoothly. Exemplarily, the drive mechanism 11 is connected to the pedal 12 ( Figure 6 ) connection. In some embodiments, Figure 8 As shown, Figure 8 The exploded structural diagram of a driving mechanism 11 provided in an embodiment of the present application is shown in FIG. The transmission mechanism 113 includes a transmission shaft 1131 , a first active connecting rod 1132 , a second active connecting rod 1133 , a first lower swing arm 1134 and a plurality of connecting shafts 1135 .

[0068] The mounting bracket 111 further includes a first mounting side wall 1113 and a second mounting side wall 1114. The mounting bracket 111, the first active link 1132, the second active link 1133 and the first lower swing arm 1134 form a four-bar linkage, and the mounting bracket 111 serves as a frame in the four-bar linkage.

[0069] One end of the transmission shaft 1131 is fixedly connected to the driving motor 112, and the other end of the transmission shaft 1131 is sequentially passed through the first installation side wall 1113, the first active connecting rod 1132 and the second installation side wall 1114. Figure 7 As shown, the plurality of connecting shafts 1135 include a first connecting shaft 11351, a second connecting shaft 11352 and a third connecting shaft 11353. The first connecting shaft 11351 is respectively connected to the first active link 1132 and the first lower swing arm 1134. The second connecting shaft 11352 is respectively connected to the first mounting side wall 1113, the second active link 1133 and the second mounting side wall 1114. The third connecting shaft 11353 is respectively connected to the second active link 1133 and the first lower swing arm 1134.

[0070] In addition, the transmission shaft 1131 is fixedly connected to the first active connecting rod 1132. A plurality of connecting shafts 1135 are respectively fixedly connected to the first active connecting rod 1132 and the second active connecting rod 1133. Exemplarily, the transmission shaft 1131 is connected to the first active connecting rod 1132 by bolts. Exemplarily, a plurality of connecting shafts 1135 are respectively interference fit with the first active connecting rod 1132 and the second active connecting rod 1133. The transmission shaft 1131 is movably connected to the mounting bracket 111, and a plurality of connecting shafts 1135 are movably connected to the mounting bracket 111 and are movably connected to one end of the first lower swing arm 1134.

[0071] In this way, the four hinge points of the four-bar linkage are formed by the transmission shaft 1131 and the multiple connecting shafts 1135, so that the four-bar linkage can achieve the movement of extension and retraction.

[0072] In some embodiments, the first lower swing arm 1134 is connected to the pedal 12 at the other end connected to the connecting shaft 1135. In this way, the driving motor 112 can drive the transmission mechanism 113 to achieve the extension and retraction of the pedal 12.

[0073] In some embodiments, Fig. 9 As shown, Fig. 9 The following is an exploded structural diagram of a driven mechanism 13 provided in an embodiment of the present application. The driven mechanism 13 includes a mounting base 131, a first intermediate connecting rod 132, a second intermediate connecting rod 133, a second lower swing arm 134 and a plurality of connecting shafts 135. Figure 3 As shown, the driven mechanism 13 is fixedly connected to the door sill 2 via a mounting base 131 .

[0074] like Fig.10 As shown, Fig.10The following is a schematic diagram of the structure of a driven mechanism 13 provided in an embodiment of the present application. The mounting base 131, the first intermediate link 132, the second intermediate link 133 and the second lower swing arm 134 form a four-bar linkage, and a plurality of connecting shafts 135 are respectively fixedly connected to the first intermediate link 132 and the second intermediate link 133 as hinge points, and are movably connected to the second lower swing arm 134 and the mounting base 131. In this way, the driven mechanism 13 can be extended and retracted.

[0075] For example, Fig.11 As shown, Fig.11 The schematic diagram of the structure of a driven mechanism 13 provided in the embodiment of the present application is shown in FIG. The second lower swing arm 134 is stepped and has a T-shaped slideway on the upper surface. Figure 5 ) card connection.

[0076] Likewise, the first lower swing arm 1134 may also maintain the same structure as the second lower swing arm 134. In this way, the pedal 12 may be clamped on the first lower swing arm 1134 and the second lower swing arm 134 at the same time.

[0077] In addition, in some embodiments, the first lower swing arm 1134 can be connected to the pedal 12 by screws. In this way, the detachable connection between the first lower swing arm 1134 and the pedal 12 can be achieved, and the connection is made more stable.

[0078] In some embodiments, the second lower swing arm 134 can be connected to the pedal 12 by screws. In this way, the detachable connection between the second lower swing arm 134 and the pedal 12 can be achieved, and the connection is made more stable.

[0079] Further, such as Figure 5 As shown, the driving mechanism 11 is fixedly connected to the pedal 12 via the first lower swing arm 1134. The driven mechanism 13 is fixedly connected to the pedal 12 via the second lower swing arm 134, and both the driving mechanism 11 and the driven mechanism 13 are extended and retracted along the X direction. Based on this, when the driving mechanism 11 is extended and retracted to drive the pedal 12 to move, the pedal 12 drives the driven mechanism 13 to move, thereby realizing the synchronous extension and retraction of the driving mechanism 11 and the driven mechanism 13.

[0080] In some embodiments, the four-bar linkage of the driving mechanism 11 and the four-bar linkage of the driven mechanism 13 have the same size. In this way, the extension speed and range of the driving mechanism 11 can be kept consistent with the extension speed and range of the driven mechanism 13, making the extension of the pedal mechanism 1 smoother.

[0081] It should be noted that there is at least one driving mechanism 11 in the pedal mechanism 1, or there may be more than one. The driven mechanism 13 may not be provided, or there may be one or more.

[0082] like Figure 7As shown, the drive mechanism 11 further includes a heat insulating member 114, which is mounted on the mounting bracket 111, and the heat insulating member 114 partially surrounds the drive motor 112. The mounting bracket 111 provides a mounting position for the heat insulating member 114. Fig.12 As shown, Fig.12 The schematic diagram of a part of the structure of a vehicle 1000 provided in the embodiment of the present application. Since the heat radiation of the exhaust pipe 3 causes the pedal mechanism 1 to fail by affecting the drive motor 112. Therefore, if Fig.13 As shown, Fig.13 A partial structural schematic diagram of a vehicle 1000 provided in an embodiment of the present application. A heat insulating member 114 is provided between the drive motor 112 and the exhaust pipe 3 to prevent failure of the pedal mechanism 1 caused by heat radiation from the exhaust pipe 3. The heat insulating member 114 partially surrounds the drive motor 112, so that the shape of the heat insulating member 114 fits the drive motor 112, and heat radiation can be better isolated in a limited space.

[0083] In some embodiments, Figure 3 As shown, the vehicle 1000 further includes a docking harness 5 connected to the drive motor 112 , and the heat insulating member 114 is located between the docking harness 5 and the exhaust pipe 3 , so the heat insulating member 114 can also protect the docking harness 5 from the heat radiation of the exhaust pipe 3 .

[0084] In some embodiments, Figure 7 As shown, the mounting bracket 111 includes a mounting base plate 1111 and a first mounting side plate 1112. The first mounting side plate 1112 is disposed on the mounting base plate 1111. The driving motor 112 is disposed on one side of the first mounting side plate 1112, and the driving motor 112 is connected to the first mounting side plate 1112. In this way, the relative positions of the driving motor 112 and the first mounting side plate 1112 are fixed.

[0085] The connection between the drive motor 112 and the first mounting side plate 1112 can be a fixed connection or a detachable connection, the purpose of which is to fix the relative position of the drive motor 112 and the mounting bracket 111 so that the drive motor 112 and the mounting bracket 111 are combined into an integrated structure to avoid force transmission failure due to position changes.

[0086] For example, Figure 7 As shown, the drive motor 112 is fixed to the first mounting side plate 1112 by a plurality of fasteners, so that the position is relatively fixed, and the drive motor 112 and the first mounting side plate 1112 can be disassembled and assembled by disassembling and assembling the fasteners, so as to facilitate maintenance, replacement and transportation.

[0087] like Figure 8 As shown, the heat insulating member 114 includes a first heat insulating member 1141 and a second heat insulating member 1142. Figure 7As shown, the first heat insulating member 1141 is located on a side of the first mounting side plate 1112 close to the drive motor 112, and the first heat insulating member 1141 is connected to the first mounting side plate 1112. The first heat insulating member 1141 and the drive motor 112 are arranged side by side in a direction parallel to the first mounting side plate 1112, and a portion of the first heat insulating member 1141 is arranged opposite to the drive motor 112, and partially surrounds the drive motor 112.

[0088] Thus, the first mounting side plate 1112 fixes the mounting position of the first heat insulating member 1141, so that the first heat insulating member 1141 and the driving motor 112 are fixed in relative position. At the same time, the driving motor 112 and the first heat insulating member 1141 are kept at a certain distance, which can also reduce the influence of heat radiation on the driving motor 112.

[0089] In addition, the first heat insulating member 1141 is connected to the first mounting side plate 1112. The second heat insulating member 1142 is located on the side of the driving motor 112 and the first heat insulating member 1141 away from the first mounting side plate 1112, and is connected to the mounting bottom plate 1111 and the first heat insulating member 1141.

[0090] By connecting the first heat insulating member 1141 to the first mounting side plate 1112, connecting the second heat insulating member 1142 to the mounting bottom plate 1111, and connecting the second heat insulating member 1142 to the first heat insulating member 1141, the first heat insulating member 1141, the second heat insulating member 1142, and the mounting bracket 111 are connected as a whole, so that force can be transmitted between each other and the overall stability can be enhanced. Figure 7 As shown, the connected whole also forms a housing chamber for the drive motor 112 , thereby reducing the impact of splashing foreign objects on the drive motor 112 .

[0091] In order to better ensure the structural stability between the first heat insulating member 1141, the second heat insulating member 1142 and the mounting bracket 111, the above connection may be a fixed connection. Exemplarily, the above fixed connection is a detachable connection such as welding or threaded connection, clamping, etc.

[0092] In some embodiments, Figure 8 As shown, the first heat insulation member 1141 includes a first heat insulation board 11411 and two first connecting boards 11412. The first heat insulation board 11411 is parallel to the first mounting side board 1112, and the first heat insulation board 11411 and the driving motor 112 are arranged relatively spaced apart. The two first connecting boards 11412 are perpendicular to the first mounting side board 1112, and the two first connecting boards 11412 are respectively located on both sides of the first heat insulation board 11411, and are arranged perpendicular to the first heat insulation board 11411. Among them, the first connecting board 11412 close to the first mounting side board 1112 is connected to the first mounting side board 1112.

[0093] Since vehicle 1000( Figure 1 ) will vibrate during operation. The first heat insulation board 11411 and the drive motor 112 are arranged at a relative interval so that the drive motor 112 will not be pressed against the first heat insulation board 11411, but there is no relatively fixed connection between them, so that a large number of small collisions will occur between the drive motor 112 and the first heat insulation board 11411. These external force collisions cause the drive motor 112 to fail. In addition, the first connecting plate 11412 transforms the first heat insulation member 1141 and the first mounting side plate 1112 into surface contact. The larger contact area makes the pressure distribution more uniform, and can adapt to more connection methods, such as bonding, which improves the stability of the structure.

[0094] In some embodiments, Fig.14 As shown, Fig.14 This is a schematic diagram of the structure of a driving mechanism 11 provided in an embodiment of the present application. The driving mechanism 11 further includes a fourth fastener 115. The fourth fastener 115 penetrates the first connecting plate 11412 and the first mounting side plate 1112, and is connected to the first connecting plate 11412 and the first mounting side plate 1112. The first connecting plate 11412 and the first mounting side plate 1112 are connected by the fourth fastener 115. In this way, a detachable connection between the first heat insulating member 1141 and the mounting bracket 111 is achieved.

[0095] In some embodiments, Figure 8 As shown, the second heat insulating member 1142 includes a second connecting plate 11421 and a third connecting plate 11422. The second connecting plate 11421 is disposed opposite to and connected to the mounting bottom plate 1111. The third connecting plate 11422 is disposed perpendicular to the second connecting plate 11421 and is disposed opposite to and connected to the first connecting plate 11412 away from the first mounting side plate 1112.

[0096] In this way, the second heat insulating member 1142 is in surface contact with the first connecting plate 11412 and the mounting base plate 1111. The larger contact area makes the pressure distribution more uniform, and can adapt to more connection methods, such as bonding, thereby improving the stability of the structure. Fig.15 As shown, Fig.15 A schematic diagram of the structure of a driving mechanism 11 provided in an embodiment of the present application. The driving mechanism 11 also includes a first fastener 116, the first fastener 116 passes through the second connecting plate 11421 and the mounting base plate 1111, and the first fastener 116 is connected to the second connecting plate 11421 and the mounting base plate 1111. The second connecting plate 11421 and the mounting base plate 1111 are connected by the first fastener 116. In this way, a detachable connection between the second heat insulating member 1142 and the mounting bracket 111 is achieved. Among them, force transmission between each other can be achieved through this connection method.

[0097] In some embodiments, Fig.15 As shown, the driving mechanism 11 further includes a second fastener 117, the second fastener 117 penetrates the third connecting plate 11422 and the first connecting plate 11412, and the third connecting plate 11422 is connected to the first connecting plate 11412. The third connecting plate 11422 and the first connecting plate 11412 are connected by the second fastener 117. In this way, a detachable connection between the first thermal insulation member 1141 and the second thermal insulation member 1142 is achieved. Among them, force transmission between each other can be achieved through this connection method.

[0098] In order to further improve the stability of the connection between the first thermal insulation member 1141 and the second thermal insulation member 1142. In some embodiments, Fig.15 As shown, the first thermal insulation member 1141 further includes a fourth connecting plate 11413. The fourth connecting plate 11413 is located on a side of the first thermal insulation member 11411 close to the mounting base plate 1111, and is connected to the first thermal insulation member 11411. The fourth connecting plate 11413 is arranged opposite to the second connecting plate 11421, and is located on a side of the second connecting plate 11421 away from the driving motor 112, and is connected to the second connecting plate 11421. In this way, the contact between the first thermal insulation member 1141 and the second thermal insulation member 1142 can be converted into surface contact, thereby improving the diversity and stability of the connection method.

[0099] In some embodiments, Fig.15 As shown, the driving mechanism 11 further includes a third fastener 118, the third fastener 118 penetrates the fourth connecting plate 11413 and the second connecting plate 11421, and is connected to the second connecting plate 11421 and the fourth connecting plate 11413, and the second connecting plate 11421 and the fourth connecting plate 11413 are connected via the third fastener 118. In this way, the detachable connection of the first heat insulating member 1141 and the second heat insulating member 1142 is achieved.

[0100] The above-mentioned detachable connection realizes the disassembly and assembly of the driving mechanism 11 by disassembling and assembling fasteners, which facilitates the maintenance, replacement and transportation of individual components.

[0101] In some embodiments, Fig.14 As shown, the first heat insulation board 11411 has an arc-shaped edge, and the axial direction of the first heat insulation board 11411 is perpendicular to the first mounting side plate 1112. In this way, the shape of the first heat insulation board 11411 can fit the drive motor 112 as closely as possible, so that the first heat insulation board 11411 can minimize the space occupied by the drive motor 112 while protecting the drive motor 112. At the same time, the arc-shaped edge is relatively smoother and has a better effect of reflecting heat radiation.

[0102] Of course, the first heat insulation board 11411 may also be in other shapes, as long as the first heat insulation board 11411 is located between the driving motor 112 and the exhaust pipe 3 ( Fig.13 ) between them, it can play the role of isolating thermal radiation.

[0103] In some embodiments, the first heat insulating member 1141 is made of metal aluminum material. Metal aluminum has good heat radiation reflection performance and can protect the driving motor 112 by reflecting external heat radiation.

[0104] In some embodiments, the first thermal insulation member 1141 may also be ceramic, as long as the influence of thermal radiation can be isolated by this material.

[0105] The pedal mechanism 1 can be supplied as an integrated whole for use in component replacement of the vehicle 1000 , which is convenient for transportation and installation.

[0106] The above are only specific implementations of the present application, but the protection scope of the present application is not limited thereto, and any changes or substitutions within the technical scope disclosed in the present application should be included in the protection scope of the present application. Therefore, the protection scope of the present application should be based on the protection scope of the claims.
