The "first", "second" and similar terms used in the present invention do not denote any order, quantity or importance, but are only used to distinguish different components. Similarly, the terms such as "a" or "an" do not denote a quantity limitation, but mean that there is at least one. The terms such as "connected" or "coupled" are not limited to physical or mechanical connections, but may include electrical connections, whether direct or indirect. The terms such as "upper", "lower", "left" and "right" are only used to indicate relative position relationships. When the absolute position of the object being described changes, the relative position relationships will also change accordingly.

[0050] First, the electric pedal structure 100 according to an embodiment of the present invention will be specifically described below with reference to the accompanying drawings.

[0051] As Figures 1 to 5 shown, the electric pedal structure 100 according to an embodiment of the present invention includes a pedal panel 10, a connection assembly 20, a drive mechanism 30, and a protection structure.

[0052] Specifically, the pedal panel 10 is connected to the vehicle body through the connection assembly 20. The connection assembly 20 includes two four-bar linkages 21 and at least one soft connector 22. The two four-bar linkages 21 are arranged opposite and spaced apart along the length direction of the pedal panel 10. One end of each of the two four-bar linkages 21 is connected to the vehicle body, and the other end is connected to the pedal panel 10. One end of the soft connector 22 is connected to the vehicle body, the other end is connected to the pedal panel 10, and the middle section of the soft connector 22 is fixedly connected to one of the four-bar linkages 21. The drive mechanism 30 is controlled by a vehicle controller (not shown) to drive the two four-bar linkages 21 to act, so that the pedal panel 10 is in the deployed position and the retracted position. In the retracted position, the pedal panel 10 is attached to the side beam trim 70 of the vehicle body; in the deployed position, the pedal panel 10 is away from the side beam trim 70. The soft connector 22 is a connection structure made of a conventional soft material known to those skilled in the art, and the specific structure and material are not particularly limited and described. It should be noted that both the pedal panel 10 and the four-bar linkages 21 are made of lightweight aluminum alloy material, which has the advantage of light weight. The protection structure is installed on the vehicle body and is disposed outside the four-bar linkages. In actual installation, the protection structure is installed on the vehicle floor crossmember sheet metal (not shown) to shield and protect the four-bar linkages, preventing sand, gravel, road debris, etc. from entering and affecting the operation of the four-bar linkages.

[0053] Thus, for the electric pedal structure 100 according to the embodiments of the present invention, by providing the soft connecting member 22, while satisfying the operation of the four-bar linkage mechanism 21, it can avoid the electric pedal device from breaking when the vehicle encounters an emergency (such as rolling over), and parts being thrown out to cause secondary injuries, meeting the requirements of the vehicle safety regulations. It enables the pedal panel 10 to fit well with the vehicle side after retraction, with excellent vehicle integrity, which is beneficial to reducing the vehicle's wind resistance and achieving an aesthetic appearance. Through the provision of the protection structure, it can prevent sand, gravel, road debris, etc. from entering and affecting the operation of the four-bar linkage mechanism, thereby extending the service life. It should be noted that when the vehicle is unlocked, the pedal panel 10 is deployed until the deployed position through the signal of the vehicle controller; after locking, the pedal panel 10 starts to retract until the retracted position. The specific control principle is prior art, which is known and easily implemented by those skilled in the art.

[0054] According to a preferred embodiment of the present invention, the number of the soft connecting members 22 is two, and the two soft connecting members 22 are respectively fixedly connected to the two four-bar linkage mechanisms 21.

[0055] Specifically, as Figure 2 shown, the number of the soft connecting members 22 is two, corresponding to the two four-bar linkage mechanisms 21. A connecting ring 23 is respectively fixed to the left sides of the two four-bar linkage mechanisms 21. One end of each of the two soft connecting members 22 is fixed to the pedal panel 10, and the other end passes through the connecting ring 23 on the corresponding four-bar linkage mechanism 21 and is fixedly connected to the vehicle body. It should be noted that the length of the soft connecting member 22 should be greater than the distance between the pedal panel 10 and the vehicle body when the pedal panel 10 is in the deployed position, so that the pedal panel 10 can freely switch between the deployed position and the retracted position without being restricted by the length. While satisfying the operation of the four-bar linkage mechanism 21, it can avoid the electric pedal structure from breaking when the vehicle encounters an emergency (such as rolling over), and parts being thrown out to cause secondary injuries, meeting the requirements of the vehicle safety regulations. It should be noted that the connecting ring 23 can be integrally formed with the four-bar linkage mechanism 21 or welded and fixed to the four-bar linkage mechanism 21.

[0056] In some specific embodiments of the present invention, one end of any one of the four-bar linkage mechanisms 21 is connected to the vehicle body through at least one first fastener 40. One end of any one of the soft connecting members 22 is fixed to the vehicle body by one of the first fasteners 40 on its corresponding four-bar linkage mechanism 21, and the other end is fixed to the bottom of the pedal panel 10 through a second fastener 50. Optionally, the first fastener 40 is a mounting bolt, and the second fastener 50 is a fixing bolt.

[0057] Specifically, as Figure 2As shown, the upper ends of each four-bar linkage 21 are respectively fixedly connected to the vehicle body through four mounting bolts, and one of the mounting bolts fixes the upper end of the corresponding soft connector 22 to the vehicle body. This can save the use of mounting bolts and reduce the opening of bolt holes, thereby reducing production costs.

[0058] In some specific embodiments of the present invention, since the four-bar linkage 21 is arranged at a position close to the ground, it is easy for sundries such as sand grains to enter, resulting in problems such as the four-bar linkage 21 getting stuck in movement and generating abnormal noises. The electric pedal structure 100 of the embodiments of the present invention further includes a protection structure.

[0059] Specifically, as Figure 5 shown, the protection structure includes a rear protective cover 111. The rear protective cover 111 is used to install the output shaft (not shown) of the driving mechanism 30 and the four-bar linkage 21 and shield and protect the four-bar linkage 21, so as to prevent sediment, gravel, road debris, etc. from entering the four-bar linkage 21 and affecting the operation of the four-bar linkage 21. For the four-bar linkage 21, the four-bar linkage 21 includes a front swing arm 211 and a rear swing arm 212. Specifically, as Figure 5 shown, one end of the front swing arm 211 and one end of the rear swing arm 212 are both rotatably connected to the rear protective cover 111, the other end of the front swing arm 211 and the other end of the rear swing arm 212 are both rotatably connected to the pedal panel 10, and the driving mechanism 30 drives the rear swing arm 212, the front swing arm 211 and the rear protective cover 111 to form a four-bar linkage 21 through the output shaft, so as to realize the switching of the pedal panel 10 between the deployed position and the retracted position. The rear protective cover 111 is arranged at the outer rear end of the front swing arm 211 and the rear swing arm 212, that is, the front left side as Figure 5 shown. Specifically, the rear protective cover is in a cover-shaped structure with an opening at one end, that is, the right side as Figure 5 shown. The front swing arm 211 and the rear swing arm 212 are both arranged inside the opening of the rear protective cover 111. More specifically, when the four-bar linkage 20 is in the retracted position, it can be received inside the rear protective cover 111, so as to avoid sediment, gravel, road debris, etc. from entering the cavity between the front swing arm 211 and the rear swing arm 212.

[0060] In some preferred embodiments of the present invention, the protection structure further includes a shaft end protection mechanism. The shaft end protection mechanism includes a shaft end upper protective cover 112 and a shaft end lower protective cover 113. Specifically, as Figure 5As shown, the upper shaft-end protective cover 112 is disposed outside the rotational connection between the output shaft and the rear protective cover 111, and outside the rotational shafts of the front swing arm 211 and the rear swing arm 212 (not shown) that are rotationally connected to the rear protective cover 111. The lower shaft-end protective cover 113 is disposed outside the rotational shafts of the front swing arm 211 and the rear swing arm 212 (not shown) that are rotationally connected to the pedal panel 10. It protects the shaft ends of the four-bar linkage 21 to prevent sediment and dust from entering the gaps between the shafts and the bearings (not shown), which may cause problems such as jamming and abnormal noise in the mechanism movement. In addition, it should be noted that the shafts and the bearings are provided with oil storage grooves for long-term lubrication of the shafts.

[0061] In some preferred embodiments of the present invention, as Figure 1 shown, a front fender 91 and a rear fender 92 are respectively provided on both sides of the body at the side beam trim 70. When the pedal panel 10 is in the retracted position, the pedal panel 10 is received between the front fender 91 and the rear fender 92.

[0062] In some specific embodiments of the present invention, the electric pedal structure 100 further includes a lighting assembly, and the lighting assembly includes a front lighting device 61 and a rear lighting device 62.

[0063] Specifically, as Figure 3 shown, the front lighting device 61 is disposed on the outer side of the bottom end of the front door 101, and the rear lighting device 62 is disposed on the outer side of the bottom end of the rear door 102. The front lighting device 61 and the rear lighting device 62 are respectively connected to the vehicle controller. Correspondingly, a front lighting area 11 and a rear lighting area 12 that receive the lighting source and emit light are respectively formed at the front and rear positions on the pedal panel 10. When the pedal panel 10 is in the deployed position, when the front lighting device 61 works, it can irradiate on the rear lighting area 12, or when the rear lighting device 62 works, it can irradiate on the front lighting area 11. Through the setting of the lighting devices, when the night environment is relatively dark, by controlling the front lighting device 61 and / or the rear lighting device 62 to be lit, the light emitted by the front lighting device 61 irradiates on the rear lighting area 12 on the pedal panel 10 to illuminate the surrounding area and / or the light emitted by the rear lighting device 62 irradiates on the front lighting area 11 on the pedal panel 10 to illuminate the surrounding area, thereby facilitating people to get on and off the vehicle and improving the comfort and safety of people getting on and off the vehicle.

[0064] In some specific embodiments of the present invention, the lighting assembly further includes a front door lighting device 63 disposed inside the front door 101 and a rear door lighting device 64 disposed inside the rear door 102. Both the front door lighting device 63 and the rear door lighting device 64 are connected to the vehicle controller. When the pedal panel 10 is in the deployed position, the front door lighting device 63 can irradiate the rear lighting area 12 when the front door 101 is opened, or the rear door lighting device 64 can irradiate the front lighting area 11 when the rear door 102 is opened. By the door opening action, the front door lighting device 63 and / or the rear door lighting device 64 are triggered to light up, so that the light emitted by the front door lighting device 63 irradiates the rear lighting area 12 on the pedal panel 10 to illuminate the surroundings and / or the light emitted by the rear door lighting device 64 irradiates the front lighting area 11 on the pedal panel 10 to illuminate the surroundings, thus facilitating people to get on and off the vehicle and improving the comfort and safety of people getting on and off the vehicle. That is to say, in addition to the above-mentioned front lighting device 61 and rear lighting device 62 for facilitating people to get on and off the vehicle at night, it can also be achieved by triggering the rear door lighting device 64 and / or the front door lighting device 63 by opening the door.

[0065] In some specific embodiments of the present invention, the lighting assembly further includes an exterior mirror lighting device 65 disposed at the bottom side of the back of the exterior mirror. The exterior mirror lighting device 65 is connected to the vehicle controller and can irradiate the front lighting area 11 and the rear lighting area 12 when the pedal panel 10 is in the deployed position. That is to say, in addition to the above-mentioned front lighting device 61, rear lighting device 62, front door lighting device 63 and rear door lighting device 64 for facilitating people to get on and off the vehicle at night, it can also be achieved by the exterior mirror lighting device 65.

[0066] In some specific embodiments of the present invention, in order to achieve the personalization and sense of ceremony of contemporary vehicles, a welcome light strip 80 is further provided on the pedal panel 10 to realize the welcome function.

[0067] Specifically, as Figure 3 shown, the welcome light strip 80 is provided at the outermost end of the pedal panel 10 in the deployed position, that is, the end far from the vehicle body, and extends along the length direction of the pedal panel 10. The welcome light strip 80 is sequentially lit by the vehicle controller signal when the vehicle is unlocked and locked, and functions such as simultaneously lighting up a breathing light (not shown) are also realized. The lighting of the welcome light strip 80 has the function of reminding people beside the vehicle to prevent the pedal panel 10 from hitting people's calves when it is deployed.

[0068] In some preferred embodiments of the present invention, a vehicle control unit is provided with a PWM (Pulse Width Modulation) control motor power output module, which decelerates the motor when the electric pedal structure 100 is extended to the end, reducing the impact sound when the four-link mechanism 21 is extended to the end; and decelerates the motor when the electric pedal structure 100 is retracted to the end, reducing the impact sound when the four-link mechanism 21 is retracted to the end, thus enhancing the user's pleasure in use.

[0069] Specifically, as Figure 6 shown, both ends of the drive motor are respectively connected to drive port 1 and drive port 2. When PWM output port 1 = 1 and PWM output port 2 = 0, drive port 1 is positive and the drive motor rotates forward; when PWM output port 1 = 0 and PWM output port 2 = 1, drive port 2 is positive and the drive motor rotates in reverse.

[0070] Specific control: When the drive motor rotates forward, PWM output port 2 remains 0, the frequency of PWM output port 1 is set to 20KHz, and the rotational speed is adjusted by adjusting the duty cycle of the output waveform of "PWM output port 1". The duty cycle ranges from 1 to 0, and the motor speed gradually decreases. When the drive motor rotates in reverse, PWM output port 1 remains 0, the frequency of PWM output port 2 is set to 20KHz, and the rotational speed is adjusted by adjusting the duty cycle of the output waveform of "PWM output port 2".

[0071] In summary, for the electric pedal structure 100 according to the embodiments of the present invention, through the setting of the soft connection member, the safety and pleasure of use of the pedal are enhanced, meeting the personalized needs of users and the requirements of vehicle safety regulations. Through the setting of the lighting device, the comfort and safety of people getting on and off the vehicle are enhanced. Through the setting of the welcome light strip 80, the functionality of the whole vehicle is enhanced. Through the design of the protective cover, the service life of the electric pedal structure 100 is extended, the failure rate is reduced, and the requirements of various vehicle use environments are met. It has the advantages of convenience, safety, and pleasure in getting on and off the vehicle, low wind resistance, user-friendly welcome, and high-reliability structural design.

[0072] The vehicle according to the second aspect embodiment of the present invention includes the electric pedal structure 100 according to the above embodiments. Since the electric pedal structure 100 according to the embodiments of the present invention has the above technical effects, therefore, the vehicle according to the embodiments of the present invention also has corresponding technical effects, that is, it has the advantages of convenience, safety, and pleasure in getting on and off the vehicle, low wind resistance, user-friendly welcome, and high-reliability structural design.

[0073] The other structures and operations of the vehicle according to the embodiments of the present invention are understandable and easy to implement for those skilled in the art, and thus will not be described in detail.
