Description

Technical Field

[0001] This utility model relates to the field of automobile manufacturing, and in particular to a pedal module mounting structure and vehicle. Background Technology

[0002] With the continuous development of automotive technology, autonomous driving has become a key development direction for the automotive industry. In autonomous driving mode, vehicles can autonomously perform operations such as acceleration, deceleration, and steering, which gradually weakens the function of traditional driving control components. Specifically, the necessity of traditional components such as the steering wheel, accelerator pedal, and brake pedal is decreasing in autonomous driving scenarios because the vehicle's control system is already able to take over most driving tasks.

[0003] However, the current accelerator and brake pedals (hereinafter collectively referred to as pedals) are not adequately designed to accommodate this shift. On one hand, the presence of the pedals occupies valuable interior space, limiting the flexibility of the interior layout and passenger movement. In autonomous vehicles, passengers may desire more freedom of movement, such as adjusting the seat to a reclined position or engaging in other activities, which is hindered by fixed pedals. On the other hand, when the vehicle switches between autonomous and manual driving modes, the fixed position of the pedals may not meet the operational needs of different modes. For example, in manual driving mode, the driver needs to depress the pedals quickly and accurately, while in autonomous driving mode, the pedals may need to be hidden or retracted to avoid interfering with the driver's normal activities.

[0004] Therefore, how to overcome the aforementioned shortcomings of existing technologies is a technical problem that all sectors urgently need to solve. Utility Model Content

[0061] The present invention will now be described in detail with reference to various embodiments, examples of which are presented in the accompanying drawings and described below. Although the present invention will be described in conjunction with exemplary embodiments, it should be understood that this specification is not intended to limit the present invention to these exemplary embodiments. Rather, the present invention is intended to cover not only these exemplary embodiments, but also various alternatives, modifications, equivalents and other embodiments that may be included within the spirit of the present invention and the scope defined by the appended claims.

[0062] For ease of interpretation and precise definition of the appended claims, the terms “upper,” “lower,” “front,” “rear,” “left,” “right,” “top,” and “bottom” are used to describe features of the exemplary embodiments with reference to the positions of these features shown in the accompanying drawings.

[0063] This utility model provides a pedal module mounting structure that can be applied to vehicles and other devices that require the installation of accelerator and brake pedals. The following section uses the application of the pedal module in a vehicle as an example to describe the specific construction of the pedal module mounting structure in detail.

[0064] See Figure 1The pedal mounting structure includes a brake pedal module 10, an accelerator pedal module 20, and a base plate 30. (See next section...) Figure 2 When autonomous driving is required, the brake pedal module 10 and accelerator pedal module 20 can be adjusted to a hidden state. In this state, the brake pedal module 10 and accelerator pedal module 20 are hidden under the floor 30, and the brake pedal 11 and accelerator pedal 21 are flush with or flush with the floor 30, thereby increasing the space in front of the driver and creating a more comfortable driving environment. (See also...) Figure 3 When manual driving is required, the brake pedal module 10 and the accelerator pedal module 20 can be adjusted to the operating state. At this time, the brake pedal module 10 and the accelerator pedal module 20 are exposed on the floor 30, and the driver can operate the brake pedal 11 and the accelerator pedal 21 (the driver can press the brake pedal 11 and the accelerator pedal 21 down to a certain angle) to control the speed of the vehicle.

[0065] See Figure 1 The floor 30 has a first opening 31 and a second opening 32 at positions corresponding to the brake pedal module 10 and the accelerator pedal module 20, respectively. The brake pedal module 10 can switch between an operating state and a hidden state through the first opening 31, and the accelerator pedal module 20 can switch between an operating state and a hidden state through the second opening 32. Specifically, the brake pedal module 10 is disposed within the first opening 31 and can move vertically relative to the floor 30 within the first opening 31. When the brake pedal module 10 moves downward relative to the floor 30, it can gradually be hidden below the floor 30 through the first opening 31. When the brake pedal module 10 moves upward relative to the floor 30, it can gradually be exposed above the floor 30 through the first opening 31. Similarly, the accelerator pedal module 20 can be hidden below the floor 30 through the second opening 32, and can also be exposed above the floor 30 through the second opening 32.

[0066] See also Figures 1 to 3 The floor 30 includes a horizontal portion 33 and an inclined portion 34. The horizontal portion 33 is horizontally positioned for mounting vehicle components such as seats. The inclined portion 34 is connected to the horizontal portion 33 and is inclined upward relative to the horizontal portion 33. The inclined portion 34 is located in front of the driver, corresponding to the positions of the brake pedal module 10 and the accelerator pedal module 20. The first opening 31 and the second opening 32 are both located on the inclined portion 34. When a person is seated, their legs naturally present a certain angle. The inclined portion 34 allows the driver to maintain a more natural posture, thereby reducing driver fatigue during driving and facilitating driver rest during autonomous driving.

[0067] A pedal bracket 40 is provided at the bottom of the floor 30, and the pedal bracket 40 is rotatably connected to the bottom of the floor 30. Specifically, the pedal bracket 40 is located on the lower side of the inclined portion 34, and at a position corresponding to the first opening 31 and the second opening 32. The brake pedal module 10 and the accelerator pedal module 20 are both mounted on the top of the pedal bracket 40, wherein the brake pedal module 10 corresponds to the first opening 31, and the accelerator pedal module 20 corresponds to the second opening 32.

[0068] The pedal bracket 40 has a first position and a second position relative to the floor 30. (See also...) Figure 3 and Figure 4 When the pedal bracket 40 is in the first position, it can rotate downwards relative to the floor 30 to the second position. (See also...) Figure 2 When the pedal bracket 40 is in the second position, it can rotate upward relative to the floor 30 to the first position.

[0069] See next Figures 1 to 3 As the pedal bracket 40 rotates from the first position to the second position, the brake pedal module 10 and the accelerator pedal module 20 can gradually be hidden below the floor 30 through the first opening 31 and the second opening 32, respectively. When the pedal bracket 40 is in the first position, both the brake pedal module 10 and the accelerator pedal module 20 are exposed above the floor 30 and are in operation. The driver can operate the brake pedal 11 and the accelerator pedal 21 to control the vehicle's speed.

[0070] As the pedal bracket 40 rotates from the second position to the first position, the brake pedal module 10 and the accelerator pedal module 20 gradually emerge from the first opening 31 and the second opening 32 above the floor 30, respectively. When the pedal bracket 40 is in the second position, both the brake pedal module 10 and the accelerator pedal module 20 are hidden below the floor 30, and both are in a concealed state. At this time, the space where the driver's feet are located increases, which is beneficial for the driver to have a better experience.

[0071] See Figure 1 The pedal bracket 40 is rotatably connected to the floor 30 through the connecting part 35 of the floor 30 and its own pivot 42.

[0072] A connecting portion 35 is provided on the lower surface of the inclined portion 34, and the connecting portion 35 is located near the connection between the horizontal portion 33 and the inclined portion 34. The connecting portion 35 has a shaft hole 351 for connecting the rotating shaft 42.

[0073] The pedal bracket 40 includes a bracket body 41 and a rotating shaft 42, which is fixedly disposed at the first end of the bracket body 41. The rotating shaft 42 passes through a shaft hole 351 and is rotatable within the shaft hole 351, thereby enabling the pedal bracket 40 to be rotatably connected to the floor 30.

[0074] See also Figure 1 , Figure 11 , Figure 12 Shaft mounting portions 411 and 412 are respectively provided on the left and right sides of the first end of the bracket body 41. (See reference) Figure 6 The shaft mounting portions 411 and 412 respectively form non-circular holes 413 and 414, which are used to mount the rotating shaft 42. (See also...) Figure 5 and Figure 6 The cross-sectional shape of the rotating shaft 42 matches the cross-sectional shape of the non-circular holes 413 and 414. When the rotating shaft 42 is installed onto the bracket body 41, its two ends are held in the non-circular holes 413 and 414 on the left and right sides, respectively. Since the shapes of the rotating shaft 42 and the non-circular holes 413 and 414 match and are not circular, the rotating shaft 42 cannot rotate within the non-circular holes 413 and 414. Therefore, the rotating shaft 42 can be circumferentially fixed to the first end of the bracket body 41.

[0075] In some exemplary embodiments, the non-circular hole 413 is a through hole, and the non-circular hole 414 is a blind hole. When installing the rotating shaft 42, the rotating shaft 42 passes through the non-circular hole 413 from the right side of the shaft mounting part 411, and then continues to move to the left within the non-circular hole 413 until it is inserted into the non-circular hole 414. At this time, the two ends of the rotating shaft 42 are located in the non-circular holes 413 and 414, respectively.

[0076] See also Figure 1 , Figure 7 , Figure 9 A bushing 60 is also provided inside the shaft hole 351, and its axial dimension is the same as that of the shaft hole 351. (See reference...) Figure 9 The bushing 60 is disposed within the shaft hole 351 and is rotatable within the shaft hole 351. (See reference...) Figure 7 The bushing 60 has an inner circumferential surface 61 and an outer circumferential surface 62. (See also...) Figure 5 and Figure 7 The shape of the cross-section of the inner circumferential surface 61 matches the cross-sectional shape of the rotating shaft 42, thereby allowing the rotating shaft 42 to pass through the bushing 60. (See also...) Figure 9 When the bushing 60 is disposed within the shaft hole 351, the outer peripheral surface 62 can fit against the inner surface of the shaft hole 351. When the pedal bracket 40 rotates relative to the floor 30, the bushing 60 rotates within the shaft hole 351 along with the rotating shaft 42.

[0077] See Figure 1An actuation module 50 is also provided below the floor 30. The actuation module 50 is located on the lower side of the horizontal portion 33 and at the front end of the horizontal portion 33. The actuation module 50 is capable of driving the pedal bracket 40 to rotate relative to the floor 30.

[0078] See also Figures 1 to 3 The actuation module 50 includes an actuator 51 and an actuation gear 52, the actuation gear 52 being mounted to the output shaft (not shown) of the actuator 51. The actuator 51 is capable of generating torque and outputting torque through the actuation gear 52. The actuator 51 may be an electric motor.

[0079] See Figure 1 The pedal support 40 includes a transmission gear 43 that can mesh with the actuation gear 511 to receive the torque output by the actuation gear 511, thereby driving the pedal support 40 to rotate relative to the floor 30 via the actuator 51.

[0080] The transmission gear 43 is mounted on the rotating shaft 42 and is circumferentially fixed relative to the rotating shaft 42. When the transmission gear 43 rotates with the actuating gear 511, the transmission gear 43 can also drive the rotating shaft 42 to rotate within the shaft hole 351. Simultaneously, since the rotating shaft 42 is circumferentially fixed to the first end of the bracket 40 body, the bracket 40 body can also rotate with the rotation of the rotating shaft 42. Thus, driven by the actuator 51, the entire pedal bracket 40 can rotate relative to the floor 30.

[0081] See Figure 8 The transmission gear 43 has a gear hole 431. (See also...) Figure 5 and Figure 8 The cross-sectional shape of the gear hole 431 matches the cross-sectional shape of the rotating shaft 42; that is, both are non-circular. Therefore, after the transmission gear 43 is installed on the rotating shaft 42, the transmission gear 43 can be circumferentially fixed relative to the rotating shaft 42.

[0082] See Figure 1 The braking module includes two actuators 51, and correspondingly, two transmission gears 43 are also provided. The two transmission gears 43 are located on both sides of the connecting part 35 and are adjacent to the connecting part 35, while each actuator 51 is fixed to the bottom of the horizontal part 33 corresponding to one transmission gear 43.

[0083] participate Figure 1 A limiting sleeve 71 is also fitted around the outer circumference of the rotating shaft 42. (See also...) Figure 5 and Figure 10The cross-section of the inner circumferential surface 71 of the limiting sleeve 70 matches the shape of the cross-section of the rotating shaft 42. Two limiting sleeves 70 are provided, each located on the outer side of one of the two transmission gears 43. The side of each transmission gear 43 closest to the connecting portion 35 is defined as the inner side, and the side furthest from the connecting portion 35 is defined as the outer side. The two limiting sleeves 70 and the connecting portion 35 define the position of the two transmission gears 43 on the rotating shaft 42.

[0084] See Figure 1 and Figure 4 A locking device 80 is also provided at the bottom of the inclined portion 34. (See also...) Figure 4 The locking device 80 can restrict the rotation of the pedal support 40 after it has rotated to the first position. Specifically, refer to... Figure 2 , Figure 11 , Figure 12 The locking device 80 has a retractable locking shaft 81, and the support body of the pedal bracket 40 is provided with a locking hole 415 for receiving the locking shaft 81. After the pedal bracket 40 is rotated to the first position, that is, when the brake pedal module 10 and the accelerator pedal module 20 are in operation, the locking shaft 81 can extend into the locking hole 415, so that the pedal bracket 40 is held in the first position.

[0085] There are two locking devices 80, located at the second end of the bracket body 41 when the brake pedal module 10 and the accelerator pedal module 20 are in operation. The second end is provided with two locking holes 415, each corresponding to one locking device 80.

[0086] This utility model also provides a vehicle that adopts the installation structure of the pedal module provided above.

It is not intended to be exhaustive, nor to limit the invention to the precise forms disclosed; obviously, many changes and variations are possible in accordance with the foregoing teachings.
