Description

Technical Field

[0001] This utility model relates to the field of automated mechanical equipment, specifically to the structural optimization design and spatial optimization design of the pedal area of ​​industrial vehicles. Background Technology

[0002] Industrial vehicles are powered motor vehicles used for moving, pushing, towing, lifting, stacking, or placing various goods. Common industrial vehicles include forklifts, side forklifts, tractor-trailers, pallet trucks, stackers, etc.

[0003] For example, Chinese patent document CN202420740374.6 discloses a multi-material loading and unloading forklift, which includes a chassis, forks, a traveling mechanism, and a steering wheel. In use, the operator enters the driver's position and controls the vehicle's movement using the steering wheel, accelerator / electric switch, and brakes. It should be noted that industrial vehicles differ from ordinary vehicles; they need to stack and move heavy objects in specific industrial environments, thus requiring a high level of safety. Therefore, sensor-operated pedals are often installed on industrial vehicles to prevent accidental operation.

[0004] Sensor pedals differ from ordinary vehicle pedals, which typically refer to the accelerator / power pedal or brake pedal. These are small and generate control signals to propel the vehicle forward or brake when pressed. Sensor pedals, on the other hand, are larger and often laid flat in one area, used to sense whether the operator is in position. In practical applications, their purpose is to enhance safety. Sensor pedals often incorporate sensors, such as pressure sensors, which only allow the vehicle to power on after detecting that the operator has stepped on the pedal in the correct posture. This prevents accidental operation when the operator is not fully prepared to drive, such as touching a control switch while entering or exiting the driver's seat. Furthermore, the number of sensor pedals varies depending on the vehicle model and the driver's posture. Commonly, dual sensor pedals are used, such as standing and seated sensor pedals.

[0005] Industrial vehicles often rely on battery packs for power, requiring replacement when the battery runs out. During this replacement process, the battery pack's movement can cause interference with the sensor pedals, especially the seating position sensor pedals. This necessitates a larger cab to allow sufficient space for the battery pack to move. However, this spatial arrangement increases the vehicle's length and turning radius, impacting its maneuverability and adaptability in narrow passages. Furthermore, when the operator is standing, their lower legs collide with and abut against the seating position pedals, affecting comfort and safety, and restricting their forward visibility.

[0009] As a preferred embodiment of this utility model, the fixing frame includes a horizontally extending transverse frame and a back frame connected to the transverse frame. The near rod is closer to the back frame in the horizontal direction than the far rod. The near rod includes a folding rod connected to the fixing frame and a near-folding rod connected to the plate. The folding rod and the near-folding rod extend in different directions. The near-folding rod is used to avoid the far rod when the plate is in a folded state.

[0010] As a preferred embodiment of this utility model, when the plate is in a folded state, the folding rod is parallel to the back frame.

[0011] As a preferred embodiment of this utility model, the far rod includes an outward extension rod connected to the fixed frame and a far-bending rod connected to the plate. The outward extension rod and the far-bending rod extend in different directions. The bending direction of the outward extension rod is configured such that when the plate is in a folded state, the horizontal distance between the outward extension rod and the back frame gradually decreases in the upward direction.

[0012] As a preferred embodiment of this utility model, the fixing frame further includes a bag seat frame, which connects the back frame and the horizontal frame together, and the folding rod and the outward expansion rod are connected to the bag seat frame.

[0013] As a preferred embodiment of the present invention, the driving device includes a cylinder seat and a piston rod, the piston rod being rotatably connected to the back of the plate body, and the cylinder seat being connected to the mounting bracket.

[0014] As a preferred embodiment of the present invention, the plate body includes a main part and an outwardly protruding part connected to the main part and protruding outward in the front direction of the plate body, and the power output component of the driving device is connected in the outwardly protruding part.

[0015] As a preferred embodiment of this utility model, the fixing frame is provided with a folding sensing device for sensing the folding of the plate.

The locking sleeve passes through the transmission frame, and the abutment cap is used to abut against the surface of the transmission frame.

[0018] The dual-pedal driving device includes the aforementioned tilt-sensing pedal suitable for industrial vehicles, and also includes a standing pedal, the standing pedal being mounted at a position lower in the height direction than the mounting position of the plate.

[0019] As a preferred embodiment of this invention, both the standing pedal and the plate are equipped with pressure sensors.

[0021] In summary, this utility model has the following beneficial effects:

[0022] 1. The control panel can freely switch between open and folded states. When the user is seated, the panel is open, allowing the user to drive the vehicle normally. When the user needs to stand, the panel is folded, providing more legroom. Users can stand further forward in the cockpit, resulting in fewer blind spots, a better field of vision, and improved safety.

[0023] 2. When users need to replace the vehicle battery, the board is also in a folded state, allowing users to more easily remove the battery box from the battery compartment without colliding with the board.

[0024] 3. The overall length of the vehicle is controllable, resulting in a smaller turning radius and better adaptability to operations in narrow alleyways.

[0025] 4. The mounting bracket can improve the structural strength of the back frame and the transverse frame, and also provide installation space for the cylinder base.

[0026] 5. The folding rod can be closer to and fit the back frame when the panel is folded, thus further saving space occupied by the panel in the vehicle's length direction when folded.

[0027] 6. The inclined design of the outward-expanding bar allows the far-fetching bar to fit snugly against the closing bar.

[0028] 7. The outward-extending rod provides clearance, allowing the lower part of the board to be occupied, thus enabling the board to achieve a closer vertical flip angle. This provides users with more legroom and a better field of vision.

[0029] 8. The sensor is used to detect the approach of the board, first decelerate and then brake, or brake directly, thereby protecting the board and avoiding excessive folding. Attached Figure Description

[0039] The present invention will be further described in detail below with reference to the accompanying drawings.

[0040] This specific embodiment is merely an explanation of the present utility model and is not intended to limit the present utility model. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but as long as they are within the scope of the claims of the present utility model, they are protected by patent law.

[0041] The following description provides examples and does not limit the scope, applicability, or examples set forth in the claims. Changes may be made to the function and arrangement of the described elements without departing from the scope of this specification. Various processes or components may be appropriately omitted, substituted, or added to the examples. For example, the described methods may be performed in a different order than described, and various steps may be added, omitted, or combined. Furthermore, features described with respect to some examples may be combined into other examples.

[0042] Example 1, such as Figure 7 As shown, a vehicle, specifically an industrial vehicle, includes a body 91, one end of which is connected to forks 93 for storing and retrieving goods. A running gear 92, such as drive wheels, travel wheels, and steering wheels, is located at the bottom of the body 91. A driver's cab 94 is provided on the body 91, which includes a seat 96 and a control device 95. The control device 95 may be a multi-function steering wheel, which, in addition to steering, can also be equipped with electronic buttons for controlling the vehicle's forks, vehicle movement, mode switching, and other control functions.

[0043] The cockpit 94 is equipped with a dual-pedal driving system, specifically including a standing pedal 97 and a seating pedal. Both the standing pedal 97 and the seating pedal are equipped with sensors, such as pressure sensors, to detect whether the driver is correctly seated. When the driver is standing, their feet are on the standing pedal 97, which is detected by the pressure sensor on the standing pedal 97. When the driver is seated, sitting on the seat 96, their feet are naturally placed on the seating pedal, which is detected by the pressure sensor on the seating pedal.

[0044] Once the pressure sensor successfully detects a reading, the vehicle is powered on, and the control device 95 is activated; otherwise, it is deactivated. Furthermore, the steering wheel of the control device 95 is also equipped with a sensor. When the user holds the steering wheel with both hands, this is detected by the steering wheel sensor. The control device 95 is only activated after both the pressure sensors on the standing or seated pedals and the steering wheel sensor confirm the activation. This prevents accidental actions such as vehicle movement, steering, or fork movement caused by unprepared user input, thus improving vehicle safety.

[0045] The main innovation of this patent application lies in the structural improvement of the seating pedal, specifically, as follows: Figures 1-6 As shown, Figures 1-6 This is a schematic diagram of the specific structure of the seated pedal, also known as the flip-sensor pedal. Figure 1 and Figure 2 This is a diagram showing it in the open state. Figure 3 and Figure 4 This is a schematic diagram of it in its folded state.

[0046] In this embodiment, the plate 2 can freely switch between an open state and a folded state. The plate 2 can stop at any angle, allowing the user to adjust the angle for a comfortable foot placement. When the user is seated, the plate 2 is in the open state, allowing for normal driving. When the user needs to stand, the plate 2 is folded, providing more legroom. The user can stand further forward in the cockpit 94, resulting in fewer blind spots, a better field of vision, and improved safety. When the user needs to replace the vehicle battery, the plate 2 is also folded, allowing for easier removal of the battery pack without collision. This eliminates the need for a very long cockpit 94, making the overall vehicle length dimension controllable, resulting in a smaller turning radius and better adaptability to narrow passageways.

[0047] like Figure 1 and Figure 2 As shown, this type of flip-sensor pedal comprises four main component modules: a fixed frame 1, a plate 2, a drive device 3, and a transmission frame 4. The fixed frame 1 is directly connected to the vehicle body 91 and can be considered a stationary component; the plate 2 is the component where the user's foot steps, and it flips relative to the fixed frame 1 under the action of the drive device 3 and the transmission frame 4.

[0048] like Figure 2 and Figure 4As shown, the fixing frame 1 is L-shaped, comprising a nearly horizontally extending transverse frame 12 and a nearly vertically extending back frame 11, wherein the transverse frame 12 and the back frame 11 are connected to the mounting frame 13. The driving device 3 can adopt a driving structure commonly found in existing technologies, such as a motor, cylinder, or hydraulic cylinder. In this embodiment, an electric cylinder is used because electric cylinders are easier to install and reduce the need for hydraulic pipe connections. The cylinder seat 31 can specifically include two cylinder seat plates, which are hinged in the space between the two cylinder seat plates. Therefore, the mounting frame 13 can improve the structural strength of the back frame 11 and the transverse frame 12, and also provide installation space for the cylinder seat 31. The piston rod 32 of the hydraulic cylinder is mounted on the lower surface of the plate 2. The transmission frame 4 can adopt various transmission structures, such as multi-link or X-shaped cross frame, as long as it can match the flipping trajectory of the plate 2 under the power output of the driving device 3. In this embodiment, the transmission frame 4 uses a hyperboloid design.

[0049] Specifically, such as Figure 2 and Figure 4 As shown, there are two sets of hyperbolic rods, which are set on both sides of the bottom surface of the plate 2. Each set of hyperbolic rods has the same structure, which includes a near rod 41 and a far rod 42. The upper ends of the near rod 41 and the far rod 42 are hinged to the bottom surface of the plate 2, and the lower ends are hinged to the support frame 13.

[0050] In this embodiment, both the near rod 41 and the far rod 42 are designed with bends. Specifically, the near rod 41 includes a retractable rod 411 and a near-bend rod 412 that are bent and extended from each other. The latter connects to the plate 2 above, and the former connects to the support frame 13 below. Figure 2 and Figure 4 As shown, in the working state of the panel 2, the folding bar 412 is almost horizontal, while the retracting bar 411 gradually tilts downwards towards the back frame 11. In the retracted state of the panel 2, the retracting bar 411 is almost vertical, parallel to and close to the back frame 11.

[0051] This configuration allows the folding bar 411 to be closer to and fit the back frame 11 when the plate 2 is folded, thereby further saving space occupied by the plate 2 in the vehicle length direction when folded.

[0052] The far pole 42 also features a bending design. Specifically, the far pole 42 includes an outwardly extending pole 421 and a far-bending pole 422 that are bent and extended from each other. The latter connects to the upper plate 2, while the former connects to the lower bag support frame 13. In the folded state of the plate 2, the far-bending pole 422 is almost vertically close to the retractable pole 411, while the outwardly extending pole 421 tilts from top to bottom away from the back frame 11.

[0053] This arrangement serves two purposes: firstly, it allows the folding lever 422 to fit snugly against the retracting lever 411; secondly, it provides clearance at the outward-expanding lever 421, allowing the lower part of the panel 2 to be occupied, thus enabling the panel 2 to achieve a more vertical flipping angle. Both of these aspects further conserve space along the length of the vehicle when the panel 2 is folded, providing users with more legroom and a better field of vision.

[0054] like Figure 1 As shown, this embodiment also includes sensing control for the folded state of the panel 2. A sensor 51 is installed on the back frame 11, and a sensor 52 is installed on it. The sensor 52 can be a proximity switch or a photoelectric sensor in the prior art, used to sense the approach of the panel 2. When the panel 2 reaches the designated position and is captured by the sensor 52, it is considered that the panel 2 is folded in place, and the vehicle controller controls the drive device 3 to act, such as first decelerating and then braking, or directly braking. This protects the panel 2 and prevents excessive folding.

[0055] like Figure 2 and Figure 3 As shown, the plate 2 is not completely planar; it includes a main portion 21 and a protruding portion 22 located in its middle. The protruding portion 22 protrudes outward and upward, that is, towards the front of the plate 2, the side that the user's feet contact. Thus, the back of the protruding portion 22 naturally forms a concave cavity. The power output portion of the drive device 3, namely the piston rod 32, is connected to the concave cavity formed on the back of the protruding portion 22. This arrangement, on the one hand, increases the connection area between the piston rod 32 and the plate 2, making the force on the plate 2 more fluid; on the other hand, the concave cavity allows the plate 2 to be closer to the back frame 11, thereby further saving space in the length direction of the cockpit 94.

[0056] like Figure 5 and Figure 6 As shown, this embodiment also includes a tightening design for the transmission frame 4. The upper end of the transmission frame 4 is connected to the plate 2, and the lower end is connected to the fixed frame 1. Both connection points use tightening components 6. The principle and structure of the tightening components 6 are the same at both locations; the tightening component 6 at the upper end is used as an example here. A lower connecting frame 23 is provided below the step 21. The locking sleeve 61 is connected to the lower connecting frame 23 and passes through the lower connecting frame 23 and the transmission frame 4. The locking rod 62 is threadedly connected to the locking sleeve 61. The screw rod 62 is connected to an abutment cap 63, which abuts against the surface of the transmission frame 4. As the user tightens the screw rod 62, as... Figure 6As shown, the contact cap 63 will move to the left, bringing the transmission frame 4 to a reasonable gap relative to the lower connecting frame 23. This design prevents the gap between the transmission frame 4 and the plate 2 and the fixed frame 1 from being too loose, thus avoiding shaking and instability during transmission. Furthermore, since the seating pedal includes a pressure sensor, it needs to be able to more stably sense the pressure on the user's legs. Stable, unshaking transmission of the transmission frame 4 also increases the accuracy of the pressure sensor readings.
