Description

Technical Field

[0001] This utility model relates to the field of agricultural machinery, specifically to a composite foot accelerator and braking structure, and a vehicle. Background Technology

[0002] With the popularization of agricultural mechanization and modern transportation, compact accelerator and brake pedals with small to medium horsepower are increasingly used in agricultural production and engineering operations. These models typically use a foot-operated accelerator and brake pedal control system, where the driver controls the vehicle's acceleration and braking by pressing different pedals. In current technology, to save cab space, the accelerator and brake pedals are usually designed with a compact layout, with a small distance between them.

[0003] The existing pedal layout mainly adopts a lateral arrangement, that is, two pedals are placed side by side in the driver's foot area. While the lateral arrangement reduces the risk of misoperation, it occupies more cockpit space and affects the layout of other control components.

[0004] Especially in compact engines with low to medium horsepower, the limited space in the cockpit necessitates a balance between ease of operation and efficient space utilization in pedal layout. However, current designs often fail to meet both requirements simultaneously, resulting in poor driver comfort during extended operation and increasing the risk of accidental pedal activation in emergencies. Utility Model Content

[0005] The purpose of this utility model is to provide a composite foot accelerator and brake structure, which can optimize the layout of the foot accelerator pedal and brake pedal for small and medium horsepower compact agricultural machinery, reduce the space occupied in the cab, improve the space utilization rate, and improve driving comfort.

[0006] Another objective of this invention is to provide a vehicle that optimizes the layout of the accelerator and brake pedals for small and medium horsepower compact agricultural machinery, reducing the space occupied by the cab, increasing space utilization, and improving driving comfort.

[0007] The technical solution of this utility model is implemented as follows:

[0008] A composite foot accelerator and braking structure includes a support floor, a foot accelerator structure, and a brake pedal structure. The foot accelerator structure includes a foot accelerator body, a foot accelerator rocker arm, and a foot accelerator pedal portion. The foot accelerator pedal portion is hinged to the foot accelerator body via the foot accelerator rocker arm. The brake pedal structure includes a brake pedal and a brake rocker arm. The support floor is horizontally arranged.

[0009] The accelerator pedal body is fixedly installed at the bottom of the support floor, the accelerator pedal part is located on the support floor, and the support floor is provided with a through hole for the accelerator rocker arm to pass through;

[0010] The brake pedal and the accelerator pedal are arranged longitudinally along the front-rear direction of the vehicle. The brake pedal can be hinged to the brake shaft of the vehicle through the brake rocker arm. The brake pedal has an upper limit braking position and a lower limit braking position. The accelerator pedal has an upper limit throttle position and a lower limit throttle position.

[0011] When the brake pedal is in the upper limit braking position, the brake pedal is located above or behind the accelerator pedal. When the brake pedal is pressed down to the lower limit braking position, the brake pedal is located above or in front of the accelerator pedal.

[0012] Furthermore, the support floor is provided with a brake travel limit structure and a accelerator travel limit structure, which are used to limit the travel of the brake pedal and the travel of the accelerator pedal, respectively.

[0013] The brake travel limiting structure includes an upper brake limit structure and a lower brake limit structure. The upper brake limit structure is used to prevent the brake pedal from rotating upward and keeping it at the upper limit position. The lower brake limit structure is used to prevent the brake pedal from rotating downward and keeping it at the lower limit position.

[0014] The throttle travel limiting structure includes an upper throttle limit structure and a lower throttle limit structure. The upper throttle limit structure is used to prevent the foot accelerator pedal from rotating upward and keeping it at the upper limit position of the throttle. The lower throttle limit structure is used to prevent the foot accelerator pedal from rotating downward and keeping it at the lower limit position of the throttle.

[0015] Furthermore, when the brake pedal is at the lower limit of braking and the accelerator pedal is at the upper limit of throttle, the distance between the brake pedal and the accelerator pedal is 50-60mm.

[0016] Furthermore, when the brake pedal is at the upper limit of braking and the accelerator pedal is at the lower limit of throttle, the distance between the brake pedal and the accelerator pedal is 100~110mm.

[0017] Furthermore, when the brake pedal is at its upper limit braking position and the accelerator pedal is at its upper limit throttle position, the distance between the brake pedal and the accelerator pedal is 80~90mm.

[0018] Furthermore, the accelerator pedal portion adopts a round rod, which is arranged laterally and welded and fixed to the accelerator rocker arm.

[0019] Furthermore, in the left-right direction, the length of the accelerator pedal portion does not exceed the length of the brake pedal.

[0020] Furthermore, the top of the brake pedal is provided with an anti-slip structure, the anti-slip structure including multiple anti-slip protrusions, and a limiting block for limiting the foot is provided on the left or right side of the top of the brake pedal.

[0021] Furthermore, the brake pedal and the accelerator pedal are respectively connected to a brake rebound mechanism and an accelerator rebound mechanism.

[0024] This application provides a composite foot accelerator and brake structure, mainly applied to small and medium horsepower compact agricultural machinery models. Compared with the existing transverse arrangement of brake pedal and foot accelerator pedal, this solution arranges the brake pedal and foot accelerator pedal in a longitudinal direction along the front and rear of the vehicle. The longitudinal arrangement makes the driver's foot activity area more reasonable, reduces the space occupied in the cab, improves the space utilization rate, thereby improving driving comfort and reducing the probability of accidental touch.

[0040] The following detailed description, in conjunction with the accompanying drawings, outlines some embodiments of the present invention. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0041] Example 1

[0042] In traditional designs, the accelerator and brake pedals are arranged side-by-side horizontally, which takes up a lot of space in the cockpit. Because the cockpit space is compact, the driver is prone to accidentally touching these two pedals while driving, affecting driving comfort and safety.

[0043] To address the aforementioned deficiencies, refer to Figures 1-4 This embodiment provides a composite foot accelerator and braking structure, including a support floor 1, a foot accelerator structure 2 and a brake pedal structure 3. The foot accelerator structure 2 includes a foot accelerator body 203, a foot accelerator rocker arm 202 and a foot accelerator pedal part 201. The foot accelerator pedal part 201 is hinged to the foot accelerator body 203 through the foot accelerator rocker arm 202. The brake pedal structure 3 includes a brake pedal 3 and a brake rocker arm 4.

[0044] The support floor 1 is set horizontally; the foot accelerator body 203 is fixedly set at the bottom of the support floor 1, the foot accelerator pedal part 201 is located on the support floor 1, and the support floor 1 is provided with a through hole 101 for the foot accelerator rocker arm 202 to pass through. The through hole 101 can be a waist-shaped hole, and the length direction of the waist-shaped hole is the front-back direction.

[0045] The brake pedal 3 and the accelerator pedal portion 201 are arranged longitudinally along the front-rear direction of the vehicle. The brake rocker arm 4 is hook-shaped, and its front end is welded and fixed to the brake pedal 3. The brake pedal 3 is located on the support floor 1, and its rear end is used to connect to the vehicle's brake shaft. The brake pedal 3 can be hinged to the vehicle's brake shaft through the brake rocker arm 4, so that the brake pedal 3 can rotate around the brake shaft. A rotating cylinder 5 is provided at the rear end of the brake rocker arm 4, and the brake shaft can be installed in the rotating cylinder 5.

[0046] The brake pedal 3 has an upper limit braking position and a lower limit braking position, and the accelerator pedal part 201 has an upper limit accelerator position and a lower limit accelerator position.

[0047] When the foot presses the brake pedal 3 to its limit position, the brake pedal 3 is in the lower limit position of braking. When the foot releases the brake pedal 3, the brake pedal 3 rebounds to the initial position, that is, the upper limit position of braking.

[0048] When the brake pedal 3 is in the upper limit position of braking, the brake pedal 3 is located above or behind the accelerator pedal 201. When the brake pedal 3 is pressed down to the lower limit position of braking, the brake pedal 3 is located above or in front of the accelerator pedal.

[0049] Preferably, the accelerator pedal part 201 is a round rod, which is arranged laterally (laterally, i.e., along the left and right direction of the vehicle) and welded to the accelerator rocker arm 202.

[0050] This solution not only optimizes the layout of the brake pedal 3 and the accelerator pedal 201 by changing them to a longitudinal arrangement (one in front and one in the back), saving lateral space, but also changes the traditional accelerator pedal 201 to a round rod shape, further saving space without reducing strength and operation performance.

[0051] The brake pedal 3 and the accelerator pedal 201 each have a rotational trajectory, as detailed below:

[0052] When the brake pedal 3 is at the lower limit of braking and the accelerator pedal 201 is at the upper limit of accelerator, the distance between the brake pedal 3 and the accelerator pedal 201 is 50~60mm.

[0053] When the brake pedal 3 is at the upper limit of braking and the accelerator pedal 201 is at the lower limit of accelerator, the distance between the brake pedal 3 and the accelerator pedal 201 is 100~110mm.

[0054] When the brake pedal 3 is at the upper limit of braking and the accelerator pedal 201 is at the upper limit of throttle, the distance between the brake pedal 3 and the accelerator pedal 201 is 80~90mm.

[0055] This design specifies the exact distance range between the upper and lower limit positions of the brake pedal 3 and the accelerator pedal 201 (such as 50~60mm, 100~110mm, 80~90mm, etc.) to improve the accuracy of the pedaling action and enhance comfort.

[0056] The driver can operate the accelerator pedal 201 and the brake pedal 3 with one foot, and the two can be linked. For example, in an emergency, the driver can press the brake pedal 3 all the way down (i.e., at the lower limit of braking) to initiate braking, but the foot will not touch the accelerator pedal 201. This is equivalent to releasing the accelerator, causing the accelerator pedal 201 to automatically reset and rise to the upper limit of accelerator, reducing the throttle. Therefore, in an emergency, the driver can press the brake pedal 3 all the way down without touching the accelerator pedal 201, which not only brakes quickly but also reduces the throttle, improving operating efficiency and safety. Compared with the existing horizontal arrangement of the accelerator and brake pedals 3, this reduces the risk of accidentally pressing the accelerator in an emergency.

[0057] Example 2

[0058] Reference Figures 1-4 This embodiment provides a composite foot accelerator and braking structure, including a support floor 1, a foot accelerator structure 2 and a brake pedal structure 3. The foot accelerator structure 2 includes a foot accelerator body 203, a foot accelerator rocker arm 202 and a foot accelerator pedal part 201. The foot accelerator pedal part 201 is hinged to the foot accelerator body 203 through the foot accelerator rocker arm 202. The brake pedal structure 3 includes a brake pedal 3 and a brake rocker arm 4.

[0059] Define the forward and backward directions and the left and right directions according to the vehicle's direction of travel, such as... Figure 1 As shown.

[0060] The support floor 1 is horizontally set; the foot accelerator body 203 is fixedly set at the bottom of the support floor 1, the foot accelerator pedal part 201 is located on the support floor 1, and the support floor 1 is provided with a through hole 101 for the foot accelerator rocker arm 202 to pass through.

[0061] The brake pedal 3 and the accelerator pedal portion 201 are arranged longitudinally along the front-rear direction of the vehicle (this longitudinal arrangement is in contrast to the transverse arrangement of existing solutions). The brake rocker arm 4 is hook-shaped, and its front end is welded and fixed to the brake pedal 3. The brake pedal 3 is located on the support floor 1, and its rear end is used to connect to the vehicle's brake shaft. The brake pedal 3 can be hinged to the vehicle's brake shaft through the brake rocker arm 4, so that the brake pedal 3 can rotate around the brake shaft. A rotating cylinder 5 is provided at the rear end of the brake rocker arm 4, and the brake shaft can be installed in the rotating cylinder 5.

[0062] The brake pedal 3 has an upper limit braking position and a lower limit braking position, and the accelerator pedal part 201 has an upper limit accelerator position and a lower limit accelerator position.

[0063] When the foot presses the brake pedal 3 to its extreme position, the brake pedal 3 is at the lower limit of braking, and the brake is fully depressed. When the foot releases the brake pedal 3, the brake pedal 3 returns to its initial position, which is the upper limit of braking, and the brake is fully released. When the foot presses the accelerator pedal 201 to its extreme position, the brake pedal 3 is at the lower limit of accelerator, and the accelerator is at its maximum. When the foot releases the accelerator pedal 201, the accelerator pedal 201 returns to its initial position, which is the upper limit of accelerator, and the accelerator is at its minimum.

[0064] When the brake pedal 3 is in the upper limit position of braking, the brake pedal 3 is located above or behind the accelerator pedal part 201. When the brake pedal 3 is pressed down to the lower limit position of braking, the brake pedal 3 is located above or in front of the accelerator pedal part 201.

[0065] Specifically, the support floor 1 is provided with a brake travel limit structure and a accelerator travel limit structure, which are used to limit the pedal travel of the brake pedal 3 and the pedal travel of the accelerator pedal 201, respectively.

[0066] The brake travel limiting structure includes an upper brake limit structure and a lower brake limit structure. The upper brake limit structure is used to prevent the brake pedal 3 from continuing to rotate upward and keep it at the upper limit position. The lower brake limit structure is used to prevent the brake pedal 3 from continuing to rotate downward and keep it at the lower limit position.

[0067] The throttle travel limiting structure includes an upper throttle limit structure and a lower throttle limit structure. The upper throttle limit structure is used to prevent the foot accelerator pedal 201 from continuing to rotate upward and keep it at the upper limit position of the throttle. The lower throttle limit structure is used to prevent the foot accelerator pedal 201 from continuing to rotate downward and keep it at the lower limit position of the throttle.

[0068] It should be noted that the brake travel limit structure and the accelerator travel limit structure are both conventional technologies, and their structures will not be described in detail. The accelerator upper limit structure and the accelerator lower limit structure can respectively adopt an upper accelerator limit rod and a lower accelerator limit rod. The upper accelerator limit rod and the lower accelerator limit rod can be set on the support floor 1 or the vehicle frame. The upper accelerator limit rod is used to block the accelerator pedal 201 from rotating downward to the lower limit position, preventing it from rotating further downward; the upper accelerator limit rod is used to block the accelerator pedal 201 from rotating upward to the upper limit position, preventing it from rotating further upward.

[0069] The upper and lower limit braking structures are both conventional technologies, and their structures will not be described in detail. The upper and lower limit braking structures can respectively employ an upper limit brake rod and a lower limit brake rod. These rods can be mounted on the support floor 1 or the vehicle frame. The upper limit brake rod is used to block the brake pedal 3 when it rotates downwards to the lower limit braking position, preventing it from continuing to rotate downwards; the upper limit brake rod is also used to block the brake pedal 3 when it rotates upwards to the upper limit braking position, preventing it from continuing to rotate upwards.

[0070] It should be noted that the brake pedal 3 and the accelerator pedal 201 are respectively connected to a brake return mechanism and an accelerator return mechanism (both of which can be reset springs), which are used for the automatic reset of the brake pedal 3 and the accelerator pedal 201. The brake return mechanism and the accelerator return mechanism are conventional technologies (ordinary vehicles have automatic reset mechanisms for the brake pedal 3 and the accelerator pedal, for example, they can be electronic brake pedal 3 and electronic accelerator pedal respectively), and their structures will not be described in detail.

[0071] Preferably, the accelerator pedal portion 201 is made of a round rod, which is arranged laterally (laterally, i.e., along the left-right direction of the vehicle) and welded to the accelerator rocker arm 202. Along the left-right direction of the vehicle, the length of the accelerator pedal portion 201 does not exceed the length of the brake pedal 3, further reducing the size of the accelerator pedal portion 201 and reducing the space occupied.

[0072] The top of the brake pedal 3 is provided with an anti-slip structure 301, which includes multiple anti-slip protrusions. The anti-slip protrusions adopt a frustum structure. A limiting block 302 for limiting the foot is provided on the left or right side of the top of the brake pedal 3 to prevent the foot from leaving the brake pedal 3.

[0073] This solution not only optimizes the layout of the brake pedal 3 and the accelerator pedal 201 by changing them to a longitudinal arrangement (one in front and one in the back), saving lateral space, but also changes the traditional accelerator pedal 201 to a round rod shape, further saving space without reducing strength and operation performance.

[0074] The brake pedal 3 and the accelerator pedal 201 each have a rotational trajectory, as detailed below:

[0075] When the brake pedal 3 is at the lower limit of braking and the accelerator pedal 201 is at the upper limit of accelerator, the distance between the brake pedal 3 and the accelerator pedal 201 is 54mm.

[0076] When the brake pedal 3 is at the upper limit of braking and the accelerator pedal 201 is at the lower limit of accelerator, the distance between the brake pedal 3 and the accelerator pedal 201 is 103mm.

[0077] When the brake pedal 3 is at the upper limit of braking and the accelerator pedal 201 is at the upper limit of throttle, the distance between the brake pedal 3 and the accelerator pedal 201 is 85mm.

[0078] This design specifies the exact distances (such as 54mm, 103mm, 85mm, etc.) between the upper and lower limit positions of the brake pedal 3 and the accelerator pedal 201, thereby improving and ensuring the accuracy of the pedaling action and enhancing comfort.

[0079] The driver can operate the accelerator pedal 201 and the brake pedal 3 with one foot, and the two can be linked. For example, in an emergency, the driver can press the brake pedal 3 all the way down (i.e., at the lower limit of braking) to initiate braking, but the foot will not touch the accelerator pedal 201. This is equivalent to releasing the accelerator, causing the accelerator pedal 201 to automatically reset and rise to the upper limit of accelerator, reducing the throttle. Therefore, in an emergency, the driver can press the brake pedal 3 all the way down without touching the accelerator pedal 201, which not only brakes quickly but also reduces the throttle, improving operating efficiency and safety. Compared with the existing horizontal arrangement of the accelerator and brake pedals 3, this reduces the risk of accidentally pressing the accelerator in an emergency.

[0080] Example 3

[0081] A vehicle comprising the aforementioned composite foot accelerator and braking structure.

[0082] The beneficial effects of the technical solution of this utility model are:

[0083] The benefits of this plan:

[0084] 1. Improved driving comfort: The layout of the accelerator pedal 201 and brake pedal 3 is more reasonable, reducing accidental touches;

[0085] 2. Space saving: The accelerator pedal 201 and brake pedal 3 are arranged longitudinally, and the accelerator pedal 201 adopts a round rod structure to allow for more free foot movement;

[0086] 3. Improved operating logic and safety: Single-foot control of the accelerator and brake, with a linkage design suitable for emergency situations, resulting in higher safety.

[0087] 4. Strong installation adaptability: The rear end of the brake rocker arm 4 is equipped with a rotating drum 5, which has mounting holes for mounting the brake shaft on the vehicle, making it easy to fix to the vehicle chassis and other parts to ensure stable operation.

[0088] In summary, this solution is a structural optimization design. This composite foot accelerator and brake structure is mainly used in small and medium horsepower compact agricultural machinery. Compared with the existing transverse arrangement of the brake pedal 3 and foot accelerator pedal, this solution arranges the brake pedal 3 and foot accelerator pedal part 201 longitudinally along the front and rear direction of the vehicle. The longitudinal arrangement makes the driver's foot activity area more reasonable, reduces the space occupied in the cab, improves the space utilization rate, thereby improving driving comfort and reducing the probability of accidental touch, making the driver's operation easier and safer, and also easier to install on different types of vehicles.
