Description

Technical Field

[0001] This application relates to the field of automotive technology, and in particular to an electric pedal and vehicle. Background Technology

[0002] To facilitate passenger boarding and alighting, electric steps are typically installed below the vehicle doors. Electric steps usually consist of a step body and two swing arm mechanisms, with the step body typically connected to the vehicle chassis or body structure via two spaced-apart swing arm mechanisms.

[0003] However, when electric pedals are used in larger vehicles or electric cars, the span between the two swing arm mechanisms is relatively large due to factors such as adapting to the width of the vehicle doors or avoiding the chassis battery of the electric car. This causes swaying when passengers step on the pedal body between the two swing arm mechanisms to get in and out of the vehicle, resulting in insufficient stability of the electric pedal. To improve the stability of electric pedals, additional swing arm mechanisms are usually added between the two swing arm mechanisms. While this method can solve the problem of insufficient stability of electric pedals in larger vehicles, it greatly increases the manufacturing cost of electric pedals. In addition, adding additional swing arm mechanisms between the two swing arm mechanisms cannot solve the problem of insufficient stability of electric pedals in electric cars that need to avoid the chassis battery. Utility Model Content

[0004] The purpose of this application is to provide an electric pedal and vehicle to address, to some extent, the instability of the electric pedal caused by the large span between the two swing arm mechanisms when the electric pedal is applied to larger vehicle models or electric vehicles. Existing methods that add other swing arm mechanisms between the two swing arm mechanisms not only increase the manufacturing cost of the electric pedal but also fail to solve the technical problem of insufficient stability in electric pedals of electric vehicles that need to avoid the chassis battery.

[0005] According to a first aspect of this application, an electric pedal is provided, including a pedal body and a plurality of swing arm mechanisms, wherein the pedal body extends along a first direction and the plurality of swing arm mechanisms are spaced apart along the first direction;

[0006] The swing arm mechanism includes a transmission assembly and a support portion. The swing arm mechanism is connected to the pedal body via the support portion. The support portion includes a connecting arm and a support plate connected to each other. The support plate is used to support the pedal body. The transmission assembly is driven to the connecting arm to drive the pedal body to extend and retract relative to the vehicle body.

[0007] For one of the two adjacent swing arm mechanisms, the support plate extends a predetermined distance from its own connecting arm along the first direction toward the other of the two adjacent swing arm mechanisms.

[0008] Preferably, a portion of the connecting arm overlaps with the pedal body, and the support plate is disposed on one side of the portion of the connecting arm in the first direction.

[0009] Preferably, the predetermined distance is 100mm to 200mm.

[0010] Preferably, the distance between two adjacent swing arm mechanisms in the first direction is 950mm to 1400mm.

[0011] Preferably, the swing arm mechanism further includes a mounting portion for connecting to the vehicle body, and the transmission assembly connects the mounting portion and the support portion.

[0012] Preferably, the transmission assembly includes a drive arm, one end of which is hinged to the mounting portion, and the other end of which is hinged to the connecting arm.

[0013] Preferably, the transmission assembly includes a stabilizing arm, which is arranged parallel to the driving arm. One end of the stabilizing arm is hinged to the mounting portion, and the other end of the stabilizing arm is hinged to the connecting arm.

[0014] Preferably, it further includes a rotary drive unit, and the transmission component of at least one of the plurality of swing arm mechanisms is connected to the rotary drive unit in a transmission manner.

[0015] Preferably, the transmission assembly includes a first hinge shaft, and the drive arm and the mounting portion are hinged together via the first hinge shaft;

[0016] For the swing arm mechanism that is driven by the rotary drive unit, the rotary drive unit is driven by the first hinge shaft.

[0017] According to a second aspect of this application, a vehicle is provided, including the aforementioned vehicle body and the electric pedal described in any of the aforementioned technical solutions, thus possessing all the beneficial technical effects of the electric pedal, which will not be repeated here.

[0018] Compared with the prior art, the beneficial effects of this application are as follows:

[0019] The electric pedal provided in this application has a support plate for supporting the pedal body, which is arranged to extend a predetermined distance from its own connecting arm along a first direction to the other of the two adjacent swing arm mechanisms.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0034] The following reference Figures 1 to 5 This application describes an electric pedal and vehicle according to some embodiments.

[0035] See Figures 1 to 5 As shown, an embodiment of the first aspect of this application provides an electric pedal, which includes a pedal body 1 and a plurality of swing arm mechanisms. The pedal body 1 extends along a first direction F1, and the plurality of swing arm mechanisms are spaced apart along the first direction F1. Each swing arm mechanism includes a transmission assembly 22 and a support portion 21. The swing arm mechanism is connected to the pedal body 1 via the support portion 21. The support portion 21 includes a connecting arm 212 and a support plate 211 connected to each other. The support plate 211 supports the pedal body 1. The transmission assembly 22 is tractively connected to the connecting arm 212 to drive the pedal body 1 to extend and retract relative to the vehicle body. For one of two adjacent swing arm mechanisms, the support plate 211 extends a predetermined distance from its own connecting arm 212 along the first direction F1 toward the other of the two adjacent swing arm mechanisms.

[0036] According to the electric pedal provided by the above technical features, the support plate 211 for supporting the pedal body 1 is configured to extend a predetermined distance from its own connecting arm 212 along the first direction F1 to the other of the two adjacent swing arm mechanisms. In this way, the area of ​​the swing arm mechanism supporting the pedal body 1 is effectively increased, thereby shortening the distance between the pedal body 1 and the two adjacent swing arm mechanisms. This effectively improves the stability of the electric pedal while maintaining the manufacturing cost of the electric pedal.

[0037] like Figures 1 to 3 As shown in the figure, F1 can be an example of the first direction F1 described above. For ease of description, two intersecting directions on a plane perpendicular to the first direction F1 are defined as the second direction F2 and the third direction F3, respectively. F2 shown in the figure can be an example of the second direction F2 described above. F3 shown in the figure can be an example of the third direction F3 described above.

[0038] Preferably, such as Figure 1 As shown, the connecting arm 212 overlaps with the pedal body 1, and the support plate 211 is disposed on one side of the connecting arm 212 in the first direction F1. Thus, the connecting arm 212 can further widen the support portion 21 to support the size of the pedal body 1 in the first direction F1, thereby further improving the stability of the electric pedal.

[0039] Preferably, the support plate 211 and the connecting arm 212 can be connected as a single unit to improve the stability and support strength of the support part 21.

[0040] by Figure 1 The electric pedal shown includes an example of two swing arm mechanisms, the support portions of which can be in the shape of "└" and "┘" respectively.

[0041] However, this is not the only possibility. If the electric pedal includes more than two swing arm mechanisms, then in the first direction F1, the supporting portions of the two swing arm mechanisms near both ends of the pedal body can be shaped like a "└" and a "┘", respectively, while the supporting portion of the swing arm mechanism between the two swing arm mechanisms near both ends of the pedal body can be shaped like a "⊥". In other words, the aforementioned supporting portions can be shaped like a "└", a "┘", or a "⊥".

[0042] Preferably, such as Figure 1 As shown, the aforementioned predetermined distance (i.e., Figure 1 The L1 shown can be 100mm to 200mm. For example, L1 can be 100mm, 110mm, 120mm, 130mm, 140mm, 150mm, 160mm, 170mm, 180mm, 190mm, 200mm, etc.

[0043] Preferably, such as Figure 1 As shown, the distance between the two adjacent swing arm mechanisms in the first direction F1 (i.e., Figure 1 The L2 shown is 950mm to 1400mm to further ensure the stability of the electric pedal. For example, L2 can be 950mm, 1000mm, 1050mm, 1100mm, 1150mm, 1200mm, 1250mm, 1300mm, 1350mm, 1400mm, etc.

[0044] In an embodiment, such as Figures 1 to 5 As shown, the swing arm mechanism also includes a mounting part 23 for connecting to the vehicle body, and the aforementioned transmission assembly 22 can connect the mounting part 23 and the support part 21.

[0045] Preferably, such as Figure 2 , Figure 3 and Figure 5 As shown, the transmission assembly 22 may include a drive arm 225, one end of which is hinged to the mounting part 23, and the other end of which is hinged to the connecting arm 212, so as to drive the support part 21 through the drive part to drive the pedal body 1 to extend and retract relative to the vehicle body.

[0046] Preferably, the transmission assembly 22 may include a first hinge shaft 221 and a second hinge shaft 222 both extending along the first direction F1, wherein the drive arm 225 and the mounting portion 23 are hinged via the first hinge shaft 221, and the drive arm 225 and the support portion 21 are hinged via the second hinge shaft 222.

[0047] Preferably, such as Figure 2 , Figure 3 and Figure 5 As shown, the transmission assembly 22 may also include a stabilizing arm 226, which is arranged parallel to the drive arm 225. One end of the stabilizing arm 226 is hinged to the mounting part 23, and the other end of the stabilizing arm 226 is hinged to the connecting arm 212. In this way, on the one hand, the connection strength between the mounting part and the supporting part 21 of the transmission assembly 22 is improved; on the other hand, the pedal body 1 can be effectively kept flat during the process of the transmission assembly 22 driving the pedal body 1 to extend.

[0048] Preferably, such as Figure 2 , Figure 3 and Figure 5 As shown, the transmission assembly 22 may include a third hinge shaft 223 and a fourth hinge shaft 224 that both extend along the first direction F1. The stabilizer arm 226 and the mounting portion 23 are hinged together via the third hinge shaft 223, and the stabilizer arm 226 and the support portion 21 are hinged together via the fourth hinge shaft 224.

[0049] Preferably, such as Figure 2 and Figure 3 As shown, the drive arm 225 can be disposed at the end of the connecting arm 212 away from the pedal body 1 in the second direction F2, and the stabilizing arm 226 is disposed between the drive arm 225 and the pedal body 1. Thus, by disposing of the drive arm 225 at the end of the connecting arm 212 away from the pedal body 1, it is possible to effectively ensure that the drive arm 225 has sufficient driving space and prevent the drive arm 225 from interfering with other components during the extension and retraction of the pedal body 1.

[0050] In an embodiment, preferably, such as Figure 1 and Figure 5 As shown, the aforementioned electric pedal may further include a rotary drive unit 3, and the transmission assembly 22 of at least one of the plurality of swing arm mechanisms is drively connected to the rotary drive unit 3. Figure 1 Taking the indicated directions as an example, Figure 1 An example of the aforementioned electric pedal including two swing arm mechanisms is shown, wherein the left swing arm mechanism is drive-connected to the rotary drive unit 3. Figure 1 Taking the electric pedal shown as an example, the left swing arm mechanism, which is connected to the rotary drive unit 3, can be defined as the active swing arm mechanism, while the right swing arm mechanism, which is not connected to the rotary drive unit 3, can be defined as the driven swing arm mechanism.

[0051] Optionally, the aforementioned rotary drive unit 3 may be a rotary motor or other rotary drive device.

[0052] Preferably, such as Figure 1 , Figure 2 and Figure 5 As shown, for the active swing arm mechanism, the rotary drive unit 3 can be connected to the first hinge shaft 221 for transmission. In this way, on the one hand, it is convenient to fix the rotary drive unit 3 to the vehicle body; on the other hand, it can effectively extend the rotational lever arm of the drive arm 225, thereby effectively saving the driving force for the extension / retraction of the drive pedal body 1.

[0053] The second aspect of this application also provides a vehicle including the vehicle body described above and the electric pedal described in any of the above embodiments, thus possessing all the beneficial technical effects of the electric pedal, which will not be repeated here.

[0054] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this application.
