Description

Technical Field

[0001] This application relates to the field of automotive accessories, and particularly to a welcome pedal, an electric pedal device, and a vehicle. Background Art

[0002] In high-chassis vehicles, in order to facilitate the entry and exit of drivers and passengers, pedals are usually installed at the vehicle skirt. These pedals are divided into two types: fixed and electric. Electric pedals are deeply loved by users because they can automatically deploy when the vehicle door is opened to assist passengers in getting on and off, and automatically retract when the vehicle door is closed, which not only ensures the vehicle's passability, maintains the cleanliness of the appearance, but also reduces the vehicle's wind resistance.

[0003] Most existing electric pedals rely on the vehicle's built-in battery for power supply. This design requires pre-arranging power supply lines during the vehicle manufacturing process, thus increasing the assembly steps and difficulty. In addition, this type of electric pedal is only applicable to vehicles with pre-set power supply lines. For vehicles without pre-set power supply lines, installing an electric pedal requires disassembling the vehicle to lay the lines, which not only increases the installation difficulty but also prolongs the installation time. Summary of the Invention

[0004] In view of the problems existing in the above-mentioned prior art, in the first aspect of this application, a welcome pedal is provided, including: A pedal body for a driver and passengers to step on; A part for setting a battery is provided on the pedal body; The battery can be electrically connected to a driving device to supply power to the driving device; The pedal body can be connected to the driving device, so that when being driven, it can be switched between an extended state and a retracted state.

[0005] In the second aspect of this application, an electric pedal device is also disclosed, including: The above-mentioned welcome pedal; and, A driving device connected to the welcome pedal; A battery is provided on the welcome pedal and is electrically connected to the driving device.

[0006] In the third aspect of this application, a vehicle is also disclosed, including the above-mentioned electric pedal device.

[0007] In this application, there is a part on the pedal body for setting the battery, and the battery set on the pedal body can directly supply power to the driving device, so as to drive the pedal body to switch between the extended state and the retracted state through the driving device. Compared with the prior art, the driving device is no longer powered by the built-in battery of the vehicle, but directly powered by the battery set on the pedal body, eliminating the step of laying the power supply line between the built-in battery and the driving device of the vehicle, with simple and convenient operation, and saving the corresponding material cost and labor cost.

Detailed implementation manners

[0010] To make the objectives, technical solutions, and advantages of this application clearer, the technical solutions of this application will be clearly and completely described below in conjunction with specific embodiments and corresponding drawings. Apparently, the described embodiments are only a part of the embodiments of this application, rather than all of them. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in this application without creative efforts belong to the scope of protection of this application.

[0011] Traditional electric pedal devices are usually powered by the battery inside the vehicle. This design requires a circuit inside the vehicle to connect the battery and the electric pedal device. In vehicles equipped with electric pedals, the corresponding circuit needs to be preset during production.

[0012] However, electric pedal devices are often provided as optional accessories. For this reason, some vehicle manufacturers pre-install the power supply line during the assembly process for future optional installation. This results in vehicles that do not choose to install electric pedals unnecessarily bearing additional costs. On the other hand, some manufacturers choose to add the circuit and install the electric pedal only after the customer determines the optional installation. Although this approach avoids unnecessary costs, it requires disassembling part of the vehicle structure to lay the circuit, which is not only cumbersome but also increases labor costs, and there may be potential safety hazards.

[0013] It is worth mentioning that the need for electric pedals is also common in vehicles such as ships or helicopters, and is also common in some devices that simulate traditional vehicles, such as operation experience devices, teaching devices, VR game devices, etc. that simulate the operation experience of racing cars, airplanes, or ships. For the convenience of discussion, this application mainly uses common vehicles as examples for illustration.

[0014] Embodiment 1 In view of the above problems, in the first aspect of this embodiment, a welcome pedal 120 is provided, as Figure 1 , Figure 2 , Figure 17 and Figure 18 shown, including: A pedal body 121 for the driver and passengers to step on; There is a part on the pedal body 121 for installing the battery 300; The battery 300 can be electrically connected to a driving device 200 to supply power to the driving device 200; The pedal body 121 can be connected to the driving device 200, so that when driven, it can be switched between the deployed state and the retracted state.

[0015] In the welcome pedal 120 provided by the embodiment of the present invention, a special battery installation part is ingeniously designed on the pedal body 121 (such as Figure 18This innovation allows the battery 300 on the welcome tread plate 120 to directly power the drive unit 200, enabling seamless transition between the extended and retracted positions of the tread plate 121. Compared to existing designs, this design eliminates the need for powering the drive unit 200 from the vehicle's internal battery. Instead, it is independently powered by the battery 300 on the tread plate 121, eliminating the need for wiring between the vehicle's internal battery and the drive unit. This improvement not only simplifies installation and operation, but also significantly reduces material and labor costs. It also facilitates subsequent maintenance and functional expansion.

[0016] Accordingly, the second aspect of this embodiment provides an electric pedal device 100, such as Figure 1 、 Figure 2 、 Figure 17 and Figure 18 Shown, including: a welcome pedal 120; and A driving device 200 connected to the welcome pedal 120; The battery 300 is disposed on the door sill 120 and is electrically connected to the driving device 200 .

[0017] The electric pedal device 100 , due to the application of the welcome pedal 120 , eliminates the step of laying a power supply line between the vehicle's built-in battery and the drive device 200 , is simple and convenient to operate, and saves corresponding material costs and labor costs.

[0018] Furthermore, in this embodiment, the electric scooter device 100 is designed to be relatively independent of the vehicle's systems. Its power comes from its own battery 300, rather than relying on the vehicle's built-in power supply. This means that even if the vehicle malfunctions, the electric scooter device 100 can still operate normally. In particular, in some embodiments, the battery 300 of the electric scooter device 100 is removable, allowing the user to easily remove it for charging. In other embodiments, the battery 300 is fixed within the electric scooter device 100, but the user can still charge it through a dedicated charging port on the electric scooter device 100. This design increases the flexibility and convenience of using the electric scooter device 100.

[0019] Accordingly, the third aspect of this embodiment further discloses a carrier 1000, such as Figure 16 As shown, an electric pedal device 100 is included.

[0020] It can be understood that the vehicle can be a means of transportation, such as a car, an aircraft, a ship, etc. In addition, the vehicle 100 mentioned in this application also includes some devices that simulate traditional vehicles, such as operation experience devices, teaching devices, VR game devices, etc. that simulate the operation experience of a racing car, an airplane or a ship. As long as the device is loaded with people and requires the installation of an electric pedal device 100 to facilitate getting on and off, it can meet the definition of the vehicle in this application.

[0021] In some embodiments, the pedal body 121 forms a receiving cavity 1212 arranged along the length direction of the pedal body 121, and the battery 300 can be arranged in the receiving cavity 1212.

[0022] In this embodiment, the receiving cavity 1212 is cleverly embedded inside the pedal body 121, which neither affects the basic function of the pedal body 121 nor provides a dedicated space for the installation of the battery 300. This built-in design not only makes the pedal body 121 a strong housing for the battery 300, thus enhancing the protection of the battery 300, but also because the battery 300 does not protrude from the surface of the pedal body 121, greatly reducing the direct impact of the gravel that may be rolled up by the wheels during driving on the battery 300 and improving the overall safety. Such a design concept effectively balances the requirements of functionality and safety.

[0023] In some embodiments, as Figure 22 shown, the pedal body 121 may include: An upper panel 1216 having an upper surface for the driver and passengers to step on; A lower panel 1217 connected to the upper panel 1216 and having a lower surface opposite to the upper surface; The first plane M where the upper surface is located and the second plane N where the lower surface is located intersect with each other, so that one side of the cross-section of the pedal body 121 has an acute angle shape; the receiving cavity 1212 is arranged between the upper panel 1216 and the lower panel 1217.

[0024] This design maximizes the internal space of the pedal body 121 to accommodate the battery 300, while its inclined lower panel 1217 reduces the space occupation. In addition, in the on-vehicle external environment, this shape can effectively protect the pedal body 121 from the abrasion of the sand and gravel lifted when the wheels roll.

[0025] The inclined lower panel 1217 with an inclined surface structure not only optimizes the space utilization but also enhances the functionality. When the sand and gravel stirred up by the rolling wheels hit this panel, its inclined angle can effectively reduce the impact force, thereby reducing the damage to the panel. At the same time, this inclined surface also cleverly guides the sand and gravel to be reflected along a specific path, avoiding further damage that the sand and gravel may cause to the vehicle chassis. This design improves the durability while protecting the key components of the vehicle.

[0026] In some embodiments, as Figure 22 shown, the pedal body 121 may further include: A first side panel 1218 and a second side panel 1219, one side of the upper panel 1216 and the lower panel 1217 is connected by the first side panel 1218, and the other side of the upper panel 1216 and the lower panel 1217 is connected by the second side panel 1219; The second side panel 1219 is connected to the driving device 200.

[0027] Specifically, as Figure 22 shown, the upper panel 1216, the first side panel 1218, the lower panel 1217 and the second side panel 1219 are connected end to end to form the frame structure of the pedal body 121, ensuring sufficient structural strength. The first side panel 1218 faces the outside of the vehicle body, while the second side panel 1219 faces the inside of the vehicle body and is connected to the driving device 200, providing a connection and installation basis for the driving device 200. In addition, as Figure 18 shown, the accommodation cavity 1212 is located within the enclosed structure formed by the cooperation of the upper panel 1216, the first side panel 1218, the lower panel 1217 and the second side panel 1219, which enables the battery 300 disposed within the accommodation cavity 1212 to be effectively protected, thereby improving safety.

[0028] It is worth mentioning that, in this embodiment, the included angle between the third plane P where the outer wall of the first side panel 1218 is located and the first plane M is greater than the included angle between the second plane N and the first plane M. By setting it in this way, on the one hand, the edge of the pedal body 121 facing the outside of the vehicle body is not so sharp, improving safety; on the other hand, the included angle between the third plane P and the first plane M is larger, making the supporting performance of the second side panel 1219 on the upper panel 1216 better, improving structural strength.

[0029] In some embodiments, as Figure 22 shown, the pedal body 121 may further have: A first cavity 1213, disposed between the upper panel 1216, the first side panel 1218 and the cavity wall of the accommodation cavity 1212; A second cavity 1214, disposed between the lower panel 1217, the second side panel 1219 and the cavity wall of the accommodation cavity 1212.

[0030] By designing the first cavity 1213 and the second cavity 1214 inside the pedal body 121, the structure is hollowed out. This hollow design not only reduces the material usage and production cost, but also when the structure is subjected to a strong impact, the hollow part can reduce the damage caused by the impact by means of crush energy absorption, and prevent the battery from failing due to deformation, thereby improving the safety and economy of the product.

[0031] In some embodiments, such as Figure 22 shown, the second side panel 1219 has a first connection surface 1219a and a second connection surface 1219b that intersect each other, and the angle formed by the first connection surface 1219a and the first plane M is less than 90°, and the angle formed by the second connection surface 1219b and the second plane N is also less than 90°; Both the first connection surface 1219a and the second connection surface 1219b are provided with track grooves 1211, and the driving device 200 can be inserted into the track grooves 1211 and fastened to the track grooves 1211 by fasteners. The fasteners can be bolts or nuts, etc.

[0032] Such as Figure 22 shown, the design of the pedal body 121 cleverly utilizes the structure where the angles between the first connection surface 1219a and the first plane M, and between the second connection surface 1219b and the second plane N are both less than 90°. Such a design makes the first connection surface 1219a and the second connection surface 1219b present an L-shaped structure as a whole when viewed from the length direction of the pedal body 121, and the angle formed by the first connection surface 1219a and the second connection surface 1219b points to the inside of the pedal body 121, forming an inwardly concave structure. This structure allows the part of the driving device 200 connected to the pedal body 121 to occupy a part of the space of the pedal body 121, which not only helps to reduce the size of the pedal body 121, but also provides precise positioning for the installation and connection of the driving device 200, and at the same time enables the connection structure between the driving device 200 and the pedal body 121 to be hidden when the welcome pedal 120 is in the exhibition state, thus appearing more compact and beautiful.

[0033] In this embodiment, the angles between the first plane M and the second plane N, between the first connecting surface 1219a and the first plane M, and between the second connecting surface 1219b and the second plane N can all be set to 30°. This design strategy ensures that the angle formed between the first connecting surface 1219a and the second connecting surface 1219b is 90°, that is, a right angle. This L-shaped structure with a right angle not only conforms to the common standards of industrial design but also provides excellent adaptability and a wide range of applications. It should be noted that although 30° is used as the angle in this embodiment to ensure the right angle of the L-shaped structure, these angles are not fixed and can be adjusted according to actual needs to adapt to different design requirements and application scenarios.

[0034] It should be noted that in this embodiment, the design where the angles between the first plane M and the second plane N, between the first connecting surface 1219a and the first plane M, and between the second connecting surface 1219b and the second plane N are all 30°. This design is to ensure that the L-shaped structure formed by the first connecting surface 1219a and the second connecting surface 1219b can meet the common right-angle standards in factory design, thereby providing better adaptability and a wider range of applications. According to actual application requirements and conditions, the specific values of these angles can be appropriately adjusted to adapt to various different engineering environments and requirements.

[0035] In this embodiment, as Figure 22 shown, both the first connecting surface 1219a and the second connecting surface 1219b are equipped with track grooves 1211 to enable the driving device 200 to be smoothly connected and fixed by fasteners. It is worth mentioning that the pedal body 121 is usually long and narrow and is closely attached to the side of the vehicle body. The length direction of the pedal body 121 generally refers to the direction of the longer side of the pedal body 121, that is, the direction consistent with the front-rear direction of the vehicle body. As Figure 1 and Figure 22 shown, the track grooves 1211 extend along the length direction of the pedal body 121, allowing the driving device 200 to move along the track grooves 1211, thereby realizing flexible adjustment of the connection position and enhancing the convenience of installation. This design not only makes the connection position of the driving device 200 adjustable but also greatly improves the adaptability of the pedal body 121 to different vehicle models.

[0036] Considering that the installation positions of the electric pedal devices 100 of different vehicle models vary, the welcome pedal 120 in this embodiment can adjust the connection position of the driving device 200 through the design of the track grooves 1211 to adapt to vehicle models of various sizes, realizing the adaptation of the welcome pedal 120 with unified specifications to multiple vehicle models. In addition, the driving device 200 is fixed to the track grooves 1211 by fasteners, and this fixing method also facilitates the adjustment of the connection position, further enhancing the versatility and practicality of the product.

[0037] In some embodiments, as Figure 22 shown, the accommodation cavity 1212 has a first inner wall 1212a and a second inner wall 1212b that are parallel to each other, and the first inner wall 1212a is parallel to the first plane M; The first inner wall 1212a and the second inner wall 1212b are connected by an arc-shaped inner wall 1212c, so that the cross-section of the accommodation cavity 1212 is formed into an oval shape.

[0038] In this embodiment, as Figure 22 shown, the first inner wall 1212a remains parallel to the first plane M. This design improves the space utilization rate of the inner wall of the pedal body 121. In some more preferred embodiments, the second inner wall 1212b is also designed to be parallel to the first inner wall 1212a, ensuring that there are at least two mutually parallel surfaces in the accommodation cavity 1212. Such a layout not only facilitates the storage of regularly shaped batteries but also improves the adaptability of the batteries. Regularly shaped batteries are common types in the market, and their manufacturing processes are mature and safe. More importantly, the cost of these batteries is relatively low, which helps to reduce the overall material cost.

[0039] In this embodiment, the first inner wall 1212a and the second inner wall 1212b are connected by a smooth arc-shaped inner wall 1212c, forming an oval cross-section of the accommodation cavity 1212. This unique oval design is not only aesthetically pleasing but also enables the accommodation cavity 1212 to easily accommodate two waist-shaped cylindrical batteries placed side by side, thus providing significant advantages in space utilization. More specifically, in this embodiment, the design of the accommodation cavity 1212 allows two waist-shaped cylindrical batteries to be placed side by side, which not only optimizes the space occupancy but also reduces the friction force due to the smooth characteristics of the oval cross-section, facilitating the insertion and removal of the battery 300. In addition, the inner wall part of the oval structure also enhances the structural strength of the pedal body 121 and acts as a reinforcing rib. These improvements not only enhance the functionality of the product but also optimize the manufacturing cost.

[0040] Embodiment Two This embodiment provides a welcome pedal 120, an electric pedal device 100, and a vehicle 1000 to which the electric pedal device 100 is applied. This embodiment is a further improvement based on the first embodiment, and the improvement lies in: setting the battery 300 in a detachable form and providing a connection structure between the battery 300 and the driving device 200.

[0041] Specifically, as Figure 18 and Figure 27 shown, the welcome pedal 120 further includes: The battery connection plate 400 is disposed within the receiving cavity 1212. When the battery 300 is placed into the receiving cavity 1212, it can abut against the battery connection plate 400 and conduct with the contact 410 of the battery connection plate 400. The battery connection plate 400 is connected to the driving device 200 through a conducting component 420.

[0042] In this embodiment, the battery 300 is connected through a single battery connection plate 400. The battery connection plate 400 is provided with contacts 410. When the battery 300 is placed into the receiving cavity 1212 and abuts against the battery connection plate 400, it can conduct with these contacts 410. This method avoids traditional hard connections, enabling the battery 300 to be quickly connected or detached from the battery connection plate 400, greatly improving the convenience of use. This not only simplifies the installation process of the battery 300 but also brings great convenience to the replacement and maintenance of the battery 300.

[0043] The battery connection plate 400 is connected to the driving device 200 through a conducting component 420. In some embodiments, the conducting component 420 can be a wire, a circuit board, or a conductive spring piece, etc.

[0044] Further, as Figure 23 and Figure 25 shown, in some embodiments, a conducting hole 510 is formed in the pedal body 121 for the conducting component 420 to pass through; a waterproof rubber plug 520 is provided on the conducting hole 510. It should be noted that the conducting hole 510 communicates the receiving cavity 1212 inside the pedal body 121 with the external space outside the pedal body 121, so that the conducting component 420 can pass through the conducting hole 510 to connect the battery connection plate 400 located in the receiving cavity 1212 with the driving device 200 outside the pedal body 121. Moreover, since the electric pedal device 100 is an external device on a vehicle and the working environment is relatively harsh, through the provision of the waterproof rubber plug 520, the gap between the conducting hole 510 and the conducting component 420 can be sealed to prevent water and dust from entering the receiving cavity 1212.

[0045] In some embodiments, there are at least two batteries 300, and at least two batteries 300 are connected in parallel with each other and then connected to the driving device 200 through the battery connection plate 400.

[0046] Specifically, in some embodiments, the battery 300 includes two batteries. After the two batteries 300 are connected in parallel with each other, they are then connected to the driving device 200 through the battery connection plate 400. This parallel connection method allows the two batteries 300 to supply power to the driving device 200 independently or jointly. This means that even when one battery 300 is removed for charging, the other battery 300 can still continue to operate, ensuring the continuous operation of the electric pedal device 100. This flexible power management scheme not only improves the reliability of the device but also enhances the user experience. As Figure 31 shown, in some other embodiments, the number of batteries 300 can be greater than two. After the batteries 300 are connected in parallel with each other, they are then connected to the driving device 200 through the battery connection plate 400.

[0047] In some other embodiments, the battery 300 includes two batteries, which respectively correspond to both ends of the pedal body 121 in the length direction, that is, the two batteries 300 can be taken out from the two ends of the pedal body 121 in the length direction respectively. Correspondingly, the two batteries 300 respectively correspond to a battery connection plate 400, that is, the batteries 300 are respectively connected to the corresponding battery connection plates 400, and the two battery connection plates 400 are connected in parallel with each other and then connected to the driving device 200.

[0048] In some embodiments, as Figure 17 and Figure 18 shown, the accommodation cavity 1212 extends to the end of the pedal body 121; The welcome pedal 120 further includes: A cover plate 126, which covers the end of the pedal body 121 to block the accommodation cavity 1212.

[0049] Specifically, as Figure 17 and Figure 18 shown, the accommodation cavity 1212 extends to the end of the pedal body 121 so that the battery 300 can be placed into the accommodation cavity 1212 from the end of the pedal body 121 and can be smoothly engaged with the battery connection plate 400. Through the arrangement of the cover plate 126, the accommodation cavity 1212 is blocked. On the one hand, it can prevent foreign objects from entering the accommodation cavity 1212 and affecting the normal use of the battery 300; on the other hand, it can also serve as a decorative plate at the end of the pedal body 121. While protecting the battery 300, it also has a decorative function, improving the aesthetics of the pedal body 121. It should be noted that the extension design of the accommodation cavity 1212 to the end ensures the stability of the battery 300 when it is placed horizontally. Even during a bumpy driving process, it can effectively prevent the battery from slipping, enhancing the safety during use.

[0050] In some other embodiments, the battery 300 may be configured to be taken out from the bottom of the pedal body 121. Specifically, a notch communicating with the accommodation cavity 1212 is provided on the lower panel 1217 of the pedal body 121, and the cover plate 126 covers the lower panel 1217 of the pedal body 121 to block the notch.

[0051] In addition, to prevent the cover plate 126 from falling off during driving, in some other embodiments, as Figure 19 、 Figure 20 and Figure 21 shown, the pedal body 121 further has: A connection cavity 1215, which is provided beside the accommodation cavity 1212 and also extends to the end of the pedal body 121; The cover plate 126 includes a face cover 1261 and a first plug 1262 provided on the face cover 1261; the first plug 1262 is inserted into the connection cavity 1215 to connect the cover plate 126 to the pedal body 121 In this embodiment, the design of the first plug 1262 precisely matches the size of the connection cavity 1215, ensuring that after the first plug 1262 is inserted into the connection cavity 1215, the cover plate 126 can be firmly positioned at the end of the pedal body 121 by the frictional force with the inner wall of the connection cavity 1215. In addition, to enhance the connection stability between the cover plate 126 and the end of the pedal body 121, in some embodiments, multiple first plugs 1262 are used. In some embodiments, the multiple first plugs 1262 are evenly distributed on the cover plate 126 around the accommodation cavity 1212. Their arrangement does not interfere with the function of the accommodation cavity 1212. Such a design not only improves the structural stability but also optimizes the overall layout of the components.

[0052] It is worth mentioning that, in this embodiment, as Figure 20 shown, the connection cavity 1215 can be formed by the above-mentioned first cavity 1213 and second cavity 1214, that is, the parts of the first cavity 1213 and the second cavity 1214 close to the end of the pedal body 121 form the connection cavity 1215 for the first plug 1262 to be inserted. In some other embodiments, the connection cavity 1215 can be provided relatively independently of the first cavity 1213 and the second cavity 1214.

[0053] In some other embodiments, to further improve the connection firmness between the cover plate 126 and the end of the pedal body 121, as Figure 22 shown, an elastic member is provided on the first plug 1262, and the inner wall of the connection cavity 1215 protrudes to form an inner edge at a position close to the end of the pedal body 121; The first bolt 1262 forms an interference fit with the inner edge of the connection cavity 1215 through an elastic member to connect the cover plate 126 to the pedal body 121. It should be noted that the elastic member can be a rubber plug or a rubber ring.

[0054] In some embodiments, such as Figure 20 and Figure 21 shown, corresponding holes H are provided on the first bolt 1262 and the pedal body 121, and at least one of the two holes H has threads; The first bolt 1262 is inserted into the connection cavity 1215, and the two holes H are opposite to each other to connect the cover plate 126 to the pedal body 121 through a screw.

[0055] In this embodiment, the axial direction of the hole H forms a specific angle with the insertion direction of the first bolt 1262. This design enables the screw to effectively restrict the movement of the first bolt 1262 along its insertion direction when passing through the two holes H, preventing it from falling out of the connection cavity 1215. At least one hole H is provided with threads to cooperate with the screw to ensure that the screw will not fall off accidentally, thereby maintaining the stability of the first bolt 1262 in the connection cavity 1215. Specifically, in this embodiment, as Figure 20 and Figure 21 shown, the hole H on the first bolt 1262 is a threaded hole for fastening with the screw; the hole H on the pedal body 121 is a tapered counterbore for the screw to pass through and connect with the threaded hole. The design of the tapered counterbore ensures that the screw is flush with the surface of the pedal body 121 after being tightened, maintaining the cleanliness and smoothness of the surface.

[0056] In some other embodiments, such as Figure 23 、 Figure 24 and Figure 26 shown, the first bolt 1262 is provided with: a nail groove 1263; a spring 1264, arranged in the nail groove 1263; a pin 1265, constrained in the nail groove 1263 and connected to the spring 1264. The pin 1265 tends to be pushed out of the nail groove 1263 under the action of the spring 1264; a through hole 530 corresponding to the pin 1265 is provided on the pedal body 121. The pin 1265 can be inserted into the through hole 530 when the first bolt 1262 is inserted into the connection cavity 1215 to connect the cover plate 126 to the pedal body 121.

[0057] Specifically, after the first bolt 1262 is inserted into the connection cavity 1215, the pin 1265 first contacts the inner wall of the connection cavity 1215 and is pushed to compress the spring 1264 until it is submerged in the pin groove 1263; when the first bolt 1262 is inserted to the designated position in the connection cavity 1215, the position of the pin 1265 is opposite to that of the through hole 530. At this time, since it is no longer restricted by the inner wall of the connection cavity 1215, the pin 1265 pops out under the push of the spring force and inserts into the through hole 530. Substantially, in this embodiment, the pin groove 1263, the spring 1264 and the pin 1265 on the first bolt 1262 together constitute a delicate spring lock mechanism. This structural design enables the first bolt 1262 to be quickly and conveniently inserted into the connection cavity 1215 and locked under an external force, or easily unlocked and withdrawn, realizing the quick loading and unloading of the cover plate 126, facilitating the replacement and maintenance of the battery 300.

[0058] Embodiment III This embodiment discloses a welcome step 120, an electric step device 100 and a vehicle 1000. This embodiment is a further improvement based on Embodiment II, and the improvement lies in that: as Figure 31 shown, the welcome step 120 further includes: A charging device 600, electrically connected to the battery connection plate 400, for charging the battery 300.

[0059] Through the setting of the charging device 600, the battery 300 can be automatically replenished with energy during daily use. This not only reduces the power loss of the battery 300, but also reduces the charging frequency, thus significantly extending the service life of the battery 300. This design is both environmentally friendly and economical, providing users with a more convenient and durable usage experience.

[0060] In some embodiments, the charging device 600 can adopt the form of wind power generation. In this way, the battery can be charged by using wind power generation during driving, thus making full use of the speed advantage during vehicle driving and having a high charging efficiency. Specifically, as Figure 29 and Figure 28 shown, an air guide port 700 is further formed on the pedal body 121; The charging device 600 includes: A wind turbine 610, arranged in the air guide port 700; A generator 620, arranged in the air guide port 700 and connected to the wind turbine 610. The generator 620 is connected to the battery connection plate 400, and is used to convert the kinetic energy of the wind turbine 610 into electrical energy and charge the battery 300.

[0061] During driving, the wind is guided by the air inlet 700 to the wind blades 610 located within the air inlet 700, and the wind blades 610 are pushed to rotate; the rotating wind blades 610 drive the generator 620 to rotate, thereby converting the kinetic energy of the wind blades 610 into electrical energy and charging the battery 300.

[0062] Further, the air inlet 700 has an air inlet side 720 and an air outlet side 730; The air inlet side 720 is provided with a filter screen 710; The wind blades 610 are arranged at a position of the air inlet 700 close to the air outlet side 730, and the cross-sectional area of the air inlet 700 gradually decreases from the air inlet side 720 to the position where the wind blades 610 are arranged, and gradually increases from the position where the wind blades 610 are arranged to the air outlet side 730. In some embodiments, the air inlet 700 can be arranged in the accommodation cavity 1212.

[0063] Among them, the filter screen 710 arranged on the air inlet side 720 can effectively intercept foreign objects to prevent foreign objects from entering the interior of the air inlet 700, thereby avoiding damage to the wind blades 610 or affecting their rotation. Moreover, the cross-sectional area of the air inlet 700 gradually decreases from the air inlet side 720 to the position where the wind blades 610 are arranged, and gradually increases from the position where the wind blades 610 are arranged to the air outlet side 730. This setting can, on the one hand, effectively increase the wind speed at the wind blades 610 in the air inlet 700, so that the wind can drive the wind blades 610 to rotate more efficiently with higher conversion efficiency; on the other hand, it can reduce the kinetic energy loss of the wind at the air inlet 700, thereby further improving the conversion efficiency.

[0064] In some other embodiments, as Figure 18 、 Figure 30 and Figure 31 shown, the energy replenishment device 600 is arranged in the accommodation cavity 1212, including: A linear reciprocating generator 630, arranged along the length direction of the accommodation cavity 1212 and connected to the battery connection plate 400. The linear reciprocating generator 630 is used to convert the excess kinetic energy of the vehicle 1000 where the welcome pedal 120 is located during acceleration and deceleration into electrical energy and charge the battery 300.

[0065] As can be seen from the above, the accommodation cavity 1212 is formed by the pedal body 121 and is arranged along the length direction of the pedal body 121. Therefore, the linear reciprocating generator 630 is also arranged along the length direction of the accommodation cavity 1212, that is, the pedal body 121. Such a design makes full use of the space inside the pedal body 121, thereby improving the space utilization efficiency. At the same time, placing the linear reciprocating generator 630 in the accommodation cavity 1212 not only saves space but also provides additional protection for the linear reciprocating generator 630, ensuring its safety and stability during use.

[0066] As Figure 30 shown, in this embodiment, various types of linear reciprocating generators 630 in the prior art can be used. It generally includes a rotor 632 and a stator 631. When the vehicle accelerates or decelerates, the rotor 632 reciprocates relative to the stator 631 under the action of inertia, and cuts the magnetic induction lines during its reciprocating motion, thereby realizing power generation. Among them, the rotor 632 can be one of a coil and a magnetic member, and the stator 631 can be the other of a coil and a magnetic member.

[0067] Embodiment 4 This embodiment discloses a welcome pedal 120, an electric pedal device 100, and a vehicle 1000. This embodiment is a further improvement based on the first embodiment, the second embodiment, or the third embodiment. The improvement lies in that the electric pedal device 100 further includes: A mounting seat 110 for being fixed to the vehicle body side skirt, and the driving device 200 is fixed to the mounting seat 110; The driving device 200 includes: A driver 130 fixed to the mounting seat 110; A first connecting rod 140, one end of the first connecting rod 140 is drivingly connected to the driver 130; A second connecting rod 150, one end of the second connecting rod 150 is drivingly connected to the other end of the first connecting rod 140; A third connecting rod 160, one third connecting rod 160 is hinged between the mounting seat 110 and one end of the welcome pedal 120, and the other third connecting rod 160 is hinged between the mounting seat 110 and the other end of the welcome pedal 120. The other end of the second connecting rod 150 is drivingly connected to one third connecting rod 160; Wherein, under the drive of the driver 130 in the first direction, the welcome pedal 120 can swing outwards and move downwards, and the welcome pedal 120 is in the unfolded state; Wherein, under the drive of the driver 130 in the second direction, the welcome pedal 120 can swing inwards and move upwards, and the welcome pedal 120 is in the retracted state.

[0068] In this way, the electric pedal device 100 can be applicable to vehicles with a particularly high chassis, thereby assisting the driver and passengers to get in and out of the vehicle comfortably.

[0069] Please refer to Figure 1 and Figure 2 , Figure 1 which is a schematic structural diagram of the electric pedal device provided by the embodiment of the present application in the unfolded state, Figure 2This is a schematic structural diagram of the electric pedal device provided by an embodiment of the present application in the retracted state. The electric pedal device 100 may include, but is not limited to, a mounting seat 110, a welcome pedal 120, a driver 130, a first link 140, a second link 150, and a third link 160. The mounting seat 110 is used to be fixed to the vehicle body side skirt. The welcome pedal 120 is used to provide a stepping surface for the driver and passengers. The driver 130 is fixed to the mounting seat 110. One end of a first link 140 is drivingly connected to the driver 130. One end of a second link 150 is drivingly connected to the other end of a first link 140. A third link 160 is hinged between the mounting seat 110 and one end of the welcome pedal 120. Another third link 160 is hinged between the mounting seat 110 and the other end of the welcome pedal 120. The other end of a second link 150 is drivingly connected to a third link 160. Wherein, under the drive of the driver 130 in the first direction, the welcome pedal 120 can swing outwards and move downwards, and the welcome pedal 120 is in the deployed state. Wherein, under the drive of the driver 130 in the second direction, the welcome pedal 120 can swing inwards and move upwards, and the welcome pedal 120 is in the retracted state.

[0070] It can be understood that since the mounting seat 110 of the electric pedal device 100 is fixed to the vehicle body side skirt, the welcome pedal 120 is driven by the link assembly to swing outwards and move downwards and swing inwards and move upwards, so that the welcome pedal 120 can be deployed and retracted. Therefore, the electric pedal device 100 is suitable for vehicles with a particularly high chassis and can assist the driver and passengers to get in and out of the vehicle comfortably. Further, the height of the welcome pedal 120 from the ground after deployment can be adjusted by adjusting the driving stroke of the driver 130 to meet the needs of different drivers and passengers. Further, since the electric pedal device 100 does not need to be installed on the vehicle chassis, it will not affect the ground clearance and passing performance of the vehicle; further, since the link assembly composed of the first link 140, the second link 150, and the third link 160 has a large transmission ratio, the electric pedal device 100 has strong ice-breaking ability and can overcome the problem of difficult opening.

[0071] Wherein, the first direction refers to one of the clockwise direction and the counterclockwise direction. The second direction refers to the other of the clockwise direction and the counterclockwise direction.

[0072] Wherein, swinging outwards means swinging away from the vehicle body. Swinging inwards means swinging towards the vehicle body. Moving upwards means moving away from the ground. Moving downwards means moving towards the ground.

[0073] Optionally, the driver 130 can be a motor assembly. The motor assembly includes a motor and a reduction gearbox. The reduction gearbox can be a planetary gear reduction gearbox. The driver 130 can include a meshing turbine and worm. The turbine and worm can play a self-locking role.

[0074] Please refer toFigures 3 - 5 , Figure 3 is Figure 2 a front view of an embodiment of an electric pedal device Figure 4 is Figure 3 a partial enlarged view of the electric pedal device at area A Figure 5 is Figure 3 a partial enlarged view of the electric pedal device at area B. The other end of the second link 150 is hinged to the structure between the two ends of the third link 160 to obtain a first hinge center O1. One end of the second link 150 is hinged to the other end of the first link 140 to obtain a second hinge center O2. One end of a first link 140 is drivingly connected to the output shaft 131 of the driver 130, so as to drive the welcome pedal 120 to extend or retract through the second link 150 and the third link 160 under the drive of the driver 130.

[0075] Furthermore, one end of another first link 140 is hinged to the mounting seat 110 to obtain a third hinge center O3. One end of another second link 150 is hinged to the other end of another first link 140 to obtain a second hinge center O2. The other end of another second link 150 is hinged to the structure between the two ends of another third link 160 to obtain a first hinge center O1.

[0076] Furthermore, a ray starting from the second hinge center O2 and passing through the first hinge center O1 is a first ray K1. A ray starting from the second hinge center O2 and passing through the rotation center O4 of the output shaft 131 is a second ray K2. A ray starting from the second hinge center O2 and passing through the third hinge center O3 is a third ray K3.

[0077] Furthermore, when the welcome pedal 120 is in the retracted state, the first hinge center O1, the second hinge center O2, and the rotation center O4 of the output shaft 131 are located on the same straight line. Or, when the welcome pedal 120 is in the retracted state, the included angle between the first ray K1 and the second ray K2 is greater than or equal to 175° and less than or equal to 180°. The above settings enable the third link 160 to be in a self-locking state under the gravity of the third link 160 and the welcome pedal 120.

[0078] Furthermore, when the welcome pedal 120 is in the retracted state, the first hinge center O1, the second hinge center O2, and the third hinge center O3 are located on the same straight line. Or, when the welcome pedal 120 is in the retracted state, the included angle between the first ray K1 and the third ray K3 is greater than or equal to 175° and less than or equal to 180°. The above settings can strengthen the self-locking of the third link 160.

[0079] Please refer to Figure 1 , Figure 2 andFigure 6 , Figure 6 is an exploded schematic view of the electric pedal device provided by an embodiment of the present application. The electric pedal device 100 further includes a buffer pad 190. The buffer pad 190 is fixed to the mounting seat 110. When the welcome pedal 120 is in the deployed state, one side of the third link 160 abuts against a buffer pad 190 to eliminate shaking and abnormal noises, so that the welcome pedal 120 is stably in the deployed state. At the same time, when the welcome pedal 120 in the deployed state is collided, the buffer pad 190 also plays a role of buffering and protecting. When the welcome pedal 120 is in the retracted state, the other side of the third link 160 abuts against another buffer pad 190 to eliminate shaking and abnormal noises, so that the welcome pedal 120 is stably in the retracted state.

[0080] Further, the electric pedal device 100 further includes a torsion spring 180. The torsion spring 180 is disposed at the hinge joint of the third link 160 and the mounting seat 110. One end of the torsion spring 180 is fixed to the mounting seat 110. The other end of the torsion spring 180 is fixed to the third link 160.

[0081] It can be understood that when the electric pedal device 100 is in the retracted state, the acting force of the torsion spring 180 causes one side of the third link 160 to always abut against a buffer pad 190, thereby strengthening the self-locking of the third link 160 and eliminating gaps, shaking and abnormal noises. When the electric pedal device 100 is in the deployed state, the acting force of the torsion spring 180 causes the other side of the third link 160 to always abut against another buffer pad 190, thereby eliminating gaps, shaking and abnormal noises. At the same time, when the welcome pedal 120 in the deployed state is collided, the torsion spring 180 also plays a buffering role, thereby protecting the driver 130 and the welcome pedal 120.

[0082] Optionally, the torsion spring 180 can be a double torsion spring.

Flanges 141 are provided on both sides of the first connecting rod 140 to enhance the strength of the first connecting rod 140.

[0085] Please refer to Figures 6 - 8 . The threaded shaft section 1311 of the output shaft 131 passes through the first through hole 142 of the first connecting rod 140. The electric pedal device 100 further includes a nut 132. The nut 132 is screwed onto the threaded shaft section 1311 to press one end of the first connecting rod 140 against the frustum shaft section 1312, so that the connection between the first connecting rod 140 and the output shaft 131 is more firm and reliable.

The large shaft of the capped stepped shaft 170 passes through the second through hole 143 of the first connecting rod 140. The other end of the first connecting rod 140 is sleeved between the pair of capped bushings 171. The small shaft of the capped stepped shaft 170 passes through the third through hole 152 of the second connecting rod 150.

[0088] Further, the shaft cap of one capped bushing 171 is clamped between the shaft cap of the capped stepped shaft 170 and the other end of the first connecting rod 140 to increase the force transmission area.
