[0029] First, the application scenario of the utility model is briefly described. Since heavy trucks are mainly used to transport heavy and large goods, the corresponding truck size will be much larger than that of ordinary trucks. As the size of heavy trucks increases, the height of the cockpit becomes higher and higher, and it becomes more and more difficult for the driver to enter the cockpit, which makes it more and more difficult for the driver to enter the cockpit, which poses certain safety hazards.

[0030] like Figure 1 As shown, in one embodiment, an automatic pedal device is provided, including a plurality of pedal assemblies 10, a drive assembly 30 and a frame assembly 20, wherein the frame assembly 20 is respectively connected to each pedal assembly 10, the drive assembly 30 and a vehicle cockpit, wherein: the frame assembly 20 is used to support each pedal assembly 10 and the drive assembly 30, the drive assembly 30 is used to drive each pedal assembly 10 to rotate up or down based on the frame assembly 20, and there are always at least three groups of pedal assemblies 10 in a usable state.

[0031] like Figure 1 As shown, this embodiment proposes an automatic pedal device, including a plurality of pedal assemblies 10 arranged on a frame assembly 20, wherein the frame assembly 20 not only supports the automatic pedal device but also fixes the automatic pedal device to the cab of a heavy truck, wherein the width of the frame assembly 20 is approximately 0.45 meters to meet the installation conditions of the cab of a heavy truck.

[0032] When the automatic pedal device of this embodiment is working, the driving force generated by the driving assembly 30 automatically drives each pedal assembly 10 to rotate up or down based on the frame assembly 20, which can facilitate the driver to enter and exit the cockpit. When the automatic pedal device of this embodiment is working, there are always three groups of pedal assemblies 10 in a usable state, that is, at any time when the pedal assembly 10 rotates on the frame assembly 20, at least three groups of pedal assemblies 10 always face the direction where the driver needs to get on the vehicle, so that the driver can be lifted to a higher height.

[0033] Compared with the traditional one-stage pedal lifting device, the utility model is particularly suitable for heavy trucks, solving the problem of the difficulty of heavy truck drivers getting on and off the truck. The solution of the utility model is simple, low cost, easy to implement, and highly reliable. The use of the automatic pedal device of the utility model can improve the safety of the driver getting on and off the truck.

[0034] In an exemplary embodiment, each pedal assembly 10 includes a pedal body 110 and a pedal bracket 120 . The pedal body 110 is connected to the pedal bracket 120 , and the pedal bracket 120 is used to support the pedal body 110 .

[0035] The pedal body 110 represents a platform on the automatic pedal device for supporting the driver when stepping on or lifting the driver. Figure 1 and Figure 2 In the automatic pedal device of this embodiment, eight sets of pedal assemblies 10 may be included, and the pedal support 120 is connected to the driving assembly 30. Through the driving force of the driving assembly 30, the pedal support 120 drives the pedal body 110 to automatically rise or fall on the frame assembly 20. There is a certain distance between adjacent pedal bodies 110 through the support of the pedal support 120.

[0036] In one embodiment, the drive assembly 30 includes a drive structure 310 and a transmission structure 320, and the transmission structure 320 is respectively connected to the pedal assembly 10 and the drive structure 310, wherein: the drive structure 310 is used to generate a driving force so that the driving force drives the pedal assembly 10 to rise or fall through the transmission structure 320.

[0037] The driving structure 310 is a structure for providing driving force, such as a device for providing power such as a motor and a driving device connected to the motor. In this embodiment, the driving structure 310 is used to generate a driving force for driving the automatic pedal device to work automatically. The transmission structure 320 is a structure for transmitting the driving force generated by the driving structure 310 to the pedal assembly 10, such as a transmission device such as a transmission shaft and a transmission chain. The pedal assembly 10 is raised or lowered through the transmission of the transmission structure 320.

[0038] In this embodiment, by arranging a driving structure 310 and a transmission structure 320 in the driving assembly 30, the automatic pedal device can automatically rise and fall, and the control is very flexible.

[0039] like Figure 2 As shown, in an exemplary embodiment, the driving structure 310 includes a driving motor 3102, a driving chain 3106, a driving gear 3108 and a driven gear 3110, the driving chain 3106 is respectively connected to the driving motor 3102 and the driving gear 3108, the driving gear 3108 is connected to the driven gear 3110, and the driven gear 3110 is used to connect to the transmission structure 320.

[0040] The drive motor 3102 is used to generate driving force, such as a DC motor, which provides electrical energy through a DC power supply and converts the electrical energy into mechanical energy to achieve driving. The DC motor has a simple structure, is easy to control, and has good speed regulation performance, and has been widely used in various occasions.

[0041] When working, the drive motor 3102 is connected to the positive and negative poles of the vehicle circuit, and the forward and reverse rotation of the drive motor 3102 is controlled to realize the forward rotation or reverse rotation of the drive motor 3102, thereby realizing the rise or fall of the pedal assembly 10. Furthermore, the forward and reverse rotation switch of the motor needs to have an emergency stop function, so that when the vehicle is out of power or the automatic pedal device fails, the driver can climb into the cockpit without affecting the entry and exit of the cockpit.

[0042] like Figure 2 As shown, the driving motor 3102 and the driving gear 3108 are both connected to the driving chain 3106. When working, under the driving force of the driving motor 3102, the driving chain 3106 rotates and drives the driving gear 3108. At the same time, the driving gear 3108 is meshed and connected with the driven gear 3110. When the driving gear 3108 is working, the driven gear 3110 also rotates. With the rotation of the driven gear 3110, the driving force generated by the driving motor 3102 is transmitted to the transmission structure 320, so as to realize the control of the rise and fall of the pedal assembly 10.

[0043] In another embodiment, the driving structure 310 further includes a reducer 3104 , and the driving chain 3106 is connected to the driving motor 3102 via the reducer 3104 .

[0044] like Figure 2 As shown, the drive motor 3102 may be connected to the drive motor 3102 through a reducer 3104 before transmitting the drive force to the drive chain 3106. The reducer 3104 is a mechanical transmission device used to reduce the speed of the output of the drive motor 3102 and increase the output torque accordingly. The function of the reducer 3104 is to reduce the speed of the output shaft by changing the transmission ratio, thereby adapting to the speed and torque requirements of different applications, and can also achieve smooth transmission of the drive force, reduce vibration and impact, and extend the service life of the automatic pedal device.

[0045] Due to the power limitation of the vehicle-mounted electrical appliances, a high-power DC drive motor 3102 cannot be directly selected in the application. Therefore, the drive motor 3102 drives the reducer 3104, which drives the drive gear 3108 indirectly through the drive chain 3106, and then drives the driven gear 3110 through the drive gear 3108, so as to achieve the effect of three-time deceleration and torque increase to adapt to the different weights of the driver. The reducer 3104 can have a worm gear tooth structure to prevent the driver from stepping on the pedal to drive the automatic pedal device in the case of power failure.

[0046] In one embodiment, the transmission structure 320 includes a transmission chain unit and a transmission shaft unit. The transmission chain unit is connected to the transmission shaft unit and the frame assembly 20 respectively, and the transmission shaft unit is also connected to the pedal assembly 10 .

[0047] The transmission chain unit is a transmission device connected by a chain, which is used to drive the pedal assembly 10 to rotate up and down, so as to lift and lower the driver, so that the driver can easily enter the cockpit with a higher height and good safety. The transmission shaft unit is used to transmit the driving force generated by the driving structure 310 to the transmission chain unit through the transmission shaft.

[0048] In an exemplary embodiment, the transmission chain unit includes a lifting chain 3202, a sprocket, a driving chain plate 3208 and a connecting plate 3210, the sprockets are used to fix the lifting chain 3202, the lifting chain 3202 is connected to the sprocket through the driving chain plate 3208, the sprocket is also used to connect to the transmission shaft unit, and the connecting plate 3210 is used to connect the pedal assembly 10.

[0049] Still refer to Figure 2 As shown, the transmission chain unit is a chain-shaped device disposed inside the frame assembly 20 , and the transmission chain unit moves inside the frame assembly 20 to achieve the ascending and descending control of the pedal assembly 10 .

[0050] Exemplarily, the lifting chain 3202 in the transmission chain unit moves in the frame assembly 20 through the action of the driving force. The lifting chain 3202 is provided with a sprocket, a driving chain plate 3208 and a connecting plate 3210, wherein the sprocket fixes the lifting chain 3202, and the driving chain plate 3208 is also provided on the lifting chain 3202. Through the cooperation of the sprocket and the driving chain plate 3208, the rotation of the sprocket drives the rotation of the lifting chain 3202. At the same time, the lifting chain 3202 is connected to the pedal assembly 10 through the connecting plate 3210, and the pedal assembly 10 is driven to rise and fall through the rotation of the lifting chain 3202. Due to gravity, the pedal assembly 10 is kept parallel to the ground when the automatic pedal device is working.

[0051] In a further embodiment, Figure 2 As shown, the sprocket includes an upper sprocket 3204 and a lower sprocket 3206, the upper sprocket 3204 is arranged at the top of the frame assembly 20, the lower sprocket 3206 is arranged at the bottom of the frame assembly 20, and the lower sprocket 3206 is connected to the transmission shaft unit.

Figure 2 As shown, the transmission gear 3220 is also connected to the lower sprocket 3206. During operation, the transmission shaft unit works under the driving force, drives the lower sprocket 3206, rotates the transmission chain, and realizes the control of the rise and fall of the pedal device 10.

[0054] In an exemplary embodiment, the transmission shaft includes an upper transmission shaft 3212 and a lower transmission shaft 3214 , and the upper transmission shaft 3212 and the lower transmission shaft 3214 are connected via an inter-axis support frame 3218 .

[0055] Among them, the upper transmission shaft 3212 and the lower transmission shaft 3214 are balanced, and the inter-axle support frame 3218 is set between the upper transmission shaft 3212 and the lower transmission shaft 3214 to ensure the longitudinal stability of the upper transmission shaft 3212 and the lower transmission shaft 3214 and improve the overall reliability of the automatic pedal device.

[0056] In one embodiment, the automatic pedal device may also include a current overload device and a travel switch, wherein the current overload device is used to avoid device failure caused by damage to a component in the automatic pedal, and the travel switch is installed above and below the connection between the automatic pedal device and the cab to prevent the driver's feet from being squeezed during the rising or falling process of the automatic pedal device.

[0057] In one embodiment, a vehicle is provided, which includes an automatic pedal device as provided in the above embodiment. Through the automatic pedal device, the driver can stand on the pedal body 110 to enter and exit the cockpit with relatively little effort, which can fundamentally solve the problem of difficulty in getting on and off the vehicle for heavy truck drivers.

The pedal support 120 is connected to the connecting plate 3210 and the lifting chain 3202 through a chain. Due to the effect of gravity, the pedal body 110 in the pedal assembly 10 is used to keep parallel to the ground, and two upper sprockets 3204 and lower sprockets 3206 are fixedly installed on the upper and lower sides of the frame assembly 20, and the lower sprocket 3206 is connected to the driven gear 3110 of the driving assembly 30.

[0059] The drive assembly 30 includes a drive structure 310 and a transmission structure 320. The drive structure 310 includes a drive motor 3102 that generates a driving force. The drive motor 3102 is connected to the reducer 3104. The reducer 3104 is connected to the drive gear 3108 through a drive chain 3106. The drive gear 3108 is meshed with the driven gear 3110.
