Description

Technical Field

[0001] The present invention belongs to the technical field of vehicles, and in particular, the present invention relates to a pedal, a pedal device and a vehicle. Background Art

[0002] Vehicles such as off-road vehicles, buses, pickup trucks, etc. have a large ground clearance, and pedals are usually installed on the vehicle body to facilitate people to step on and get on and off the vehicle. The pedals installed on the side of the vehicle body are usually called side pedals, and those installed at the rear of the vehicle are usually called tail pedals. Traditional pedals are made of plastic or metal plates in one piece, which are long, inconvenient to carry and transport, and have poor applicability. Summary of the invention

[0003] The present invention is based on the inventor's discovery and understanding of the following facts and problems:

[0004] In order to solve the problem of inconvenience in handling and transporting the pedal, a pedal is proposed in the related art. The pedal is divided into two plates, which are detachably or pivotally connected. When handling and transporting, the two plates are disassembled from each other or stacked together by pivoting. When in use, the two plates are assembled together or aligned with each other by pivoting. However, the inventor of the present invention recognizes that different vehicles require pedals of different lengths. For this reason, different molds are required to produce plates of different lengths, resulting in a large number of molds, high production costs, and poor versatility.

[0005] The related art also proposes a telescopic pedal, which is divided into two plates, one end of which is provided with an insertion hole, and one end of the other plate is slidably arranged in the insertion hole. During handling and transportation, one plate is retracted into the other plate, and during use, one plate is pulled out from the other plate. However, the related art only recognizes the problem of inconvenience in handling and transportation of the pedal, but does not recognize the problem of poor versatility of the pedal, and thus does not teach the adjustment of the length of the pedal.

[0006] The related art also proposes a pedal with adjustable length, in which one plate body is provided with a slide groove, and another pedal is slidably inserted in the slide groove, thereby changing the length of the pedal by sliding one plate body relative to the other plate body.

[0007] However, the inventors of the present invention realized that the two plate bodies of the telescopic pedal and the length-adjustable pedal have different structures. For example, the two plate bodies of the telescopic pedal have different thicknesses. One of the pedals is provided with a socket, and one end of the other plate body is inserted into the socket. For another example, the two plate bodies of the length-adjustable pedal, one is provided with a slide groove, and the other plate body can be slidably inserted into the slide groove. Therefore, the two plate bodies need to be produced separately with different molds, and the two plate bodies have poor interchangeability, resulting in the problems of a large number of molds, high cost, and poor versatility.

[0008] The present invention aims to solve one of the technical problems in the related art at least to a certain extent.

[0009] To this end, an embodiment of the present invention provides a pedal.

[0010] An embodiment of the present invention further provides a pedal device.

[0013] The pedal of the embodiment of the present invention has a pedal section that is slidably and detachably connected by a connecting pedal section.

In addition, the length of the pedal can be adjusted by sliding the pedal section relative to the connecting pedal section. The pedal has good versatility and a wide range of applications.

[0014] Moreover, in the pedal of the embodiment of the present invention, adjacent pedal sections are assembled and connected by connecting pedal sections.

Moreover, due to the same specifications, the pedal sections can be interchangeable, which is convenient for assembly, maintenance and replacement. In addition, when multiple connecting pedal sections are used, the specifications of the connecting pedal sections can be the same, so that the same mold can be used for production, further reducing costs. In addition, the pedal of the embodiment of the present invention can not only adjust the length of the pedal by relatively sliding the pedal section and the connecting pedal section, but also assemble pedals of different lengths by adjusting the number of pedal sections and the connecting pedal sections, further improving the adjustment range of the pedal length and improving the applicability of the pedal.

[0075] Embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0076] For the convenience of description, in the description of the embodiment of the present invention, the front and rear direction refers to the front and rear direction of the vehicle after the pedal is installed on the vehicle body, wherein the direction toward the inside of the vehicle body after the pedal is installed on the vehicle body is called inner, and the direction toward the outside of the vehicle body is called outer.

[0077] refer to Figure 1-30 The pedal 100 according to the embodiment of the present invention is described. Figure 1-Figure 30 As shown, the pedal 100 of the embodiment of the present invention includes a plurality of pedal sections 110, at least one connecting pedal section 120 and a fastener 130. The adjacent pedal sections 110 include a first pedal section 110A and a second pedal section 110B, and the connecting pedal section 120 is connected in its length direction ( Figure 2 The first end 121 of the connecting pedal section 120 is slidably and detachably connected to the first pedal section 110A, and the second end 122 of the connecting pedal section 120 is slidably and detachably connected to the second pedal section 110B.

[0078] The phrase “slidably and detachably connected” means that the connecting pedal section 120 and the first pedal section 110A can slide relative to each other to increase or decrease the length of the overlapping portion between the connecting pedal section 120 and the first pedal section 110A, and the connecting pedal section 120 can be detached from the first pedal section 110A to separate the first pedal section 110A from the connecting pedal section 120. Similarly, the connecting pedal section 120 and the second pedal section 110B can slide relative to each other to increase or decrease the length of the overlapping portion between the connecting pedal section 120 and the second pedal section 110B, and the connecting pedal section 120 and the second pedal section 110B can be detached from each other to separate the second pedal section 110B from the connecting pedal section 120. Since the first pedal section 110A and the second pedal section 110B can slide relative to the connecting pedal section 120, the overall length of the pedal 100 can be adjusted by slidingly adjusting the relative positions of the first pedal section 110A, the second pedal section 110B and the connecting pedal section 120. In other words, the pedal 100 according to the embodiment of the present invention is detachable and has an adjustable length.

[0079] The fastener 130 is used to fasten the connecting pedal segment 120 and the first pedal segment 110A to fix the relative position of the connecting pedal segment 120 and the first pedal segment 110A, and is used to fasten the connecting pedal segment 120 and the second pedal segment 110B to fix the relative position of the connecting pedal segment 120 and the second pedal segment 110B.

[0080] When the pedal 100 is carried and transported, the fastener 130 is removed, the pedal section 110 and the connecting pedal section 120 are disassembled, and the pedal section 110 and the connecting pedal section 120 can be stacked, such as Figure 13-Figure 15As shown, compared with the assembled pedal 100, the stacked pedal segments 110 and the connected pedal segments 120 are much shorter in length and occupy less space, thereby improving the convenience of handling and transportation.

[0081] When the pedal 100 is assembled and installed on a vehicle for use, Figure 1-Figure 4 As shown, the pedal section 110 and the connecting pedal section 120 are connected along the length direction of the pedal ( Figure 2 The pedal sections 110 and the connecting pedal sections 120 are connected in sequence in the front-to-back direction, and the pedal sections 110 and the connecting pedal sections 120 are relatively slidable to obtain the pedal 100 of the required length, and then the adjacent pedal sections 110 and the connecting pedal sections 120 are fastened by fasteners 130, as shown in FIG. Figure 5-7 Advantageously, the overlapping lengths of the pedal section 110 and the connecting pedal section 120 are the same. When the length of the pedal 100 needs to be changed, the fastener 130 is removed, the pedal section 110 and the connecting pedal section 120 are relatively slid, and then the pedal section 110 and the connecting pedal section 120 are fastened with the fastener 130.

[0082] The pedal of the embodiment of the present invention is connected to the pedal section in a slidable and detachable manner. When carrying and transporting, the connecting pedal section is separated from the pedal section, thereby reducing the length of the pedal, reducing the volume occupied, improving the convenience of carrying and transporting, and overcoming the problem of inconvenience in carrying and transporting due to the excessive length of the pedal. Moreover, by sliding the pedal section and the connecting pedal section relative to each other, the overall length of the pedal can be adjusted and changed, thereby being applicable to the needs of pedals of different lengths and having a wide range of uses.

[0083] Moreover, in the pedal of the embodiment of the present invention, two adjacent pedal sections are connected by a connecting pedal section. Compared with the related art in which two plate bodies are directly connected, the pedal of the embodiment of the present invention can be assembled by pedal sections of the same specification, that is, the structures of multiple pedal sections can be the same, so that the pedal sections can be produced by molds of the same specification, which reduces the number of molds and reduces costs. In addition, when there are multiple connecting pedal sections, the specifications of the connecting pedal sections can be the same, so that the connecting pedal sections can be produced by molds of the same specification, which reduces the molds required for producing the connecting pedal sections and further reduces costs. Moreover, due to the same specifications, the pedal sections can be interchangeable, and the connecting pedal sections can be interchangeable, which makes it easy to assemble and maintain. In addition, not only can the length of the pedal be adjusted by relatively sliding the pedal section and the connecting pedal section, but also pedals of different lengths can be obtained by adjusting the number of pedal sections and the connecting pedal section, which further improves the applicability of the pedal.

[0084] In some embodiments, the fastener 130 may be a threaded member, such as a screw or a bolt. The pedal section 110 is provided with a fastening hole 119, and the connecting pedal section 120 is provided with a connecting fastening hole 124. The fastening hole 119 and the connecting fastening hole 124 may both be threaded holes, or one may be a threaded hole and the other may be a through hole. The threaded member 130 fits in the fastening hole 119 and the connecting fastening hole 124 to fasten the pedal section 110 and the connecting pedal section 120 to prevent the pedal section 110 and the connecting pedal section 120 from sliding relative to each other during use. When the relative position between the pedal section 110 and the connecting pedal section 120 needs to be adjusted, or when the pedal section 110 and the connecting pedal section 120 need to be disassembled and separated, the threaded member can be screwed out of the fastening hole 119 and the connecting fastening hole 124.

[0085] In some optional embodiments, such as Figure 1 and Figure 1A As shown, the pedal section 110 is provided with a plurality of fastening holes 119 arranged at intervals in the extension direction (length direction) thereof, and the connection fastening holes 124 on the connecting pedal section 120 can be selectively aligned with the fastening holes 119, and the screw member 130 is passed through the aligned connection fastening holes 124 and fastening holes 119, so as to connect and fasten the pedal section 110 and the connecting pedal section 120. By changing the aligned connection fastening holes 124 and fastening holes 119, different relative positions of the pedal section 110 and the connecting pedal section 120 can be accommodated, thereby accommodating pedals 100 of different lengths.

[0086] exist Figure 1 In the illustrated embodiment, the pedal section 110 is provided with two fastening holes 119, and the two fastening holes 119 are respectively adjacent to the two ends of the pedal section 110, and the connecting pedal section 120 is provided with more than two connecting fastening holes 124, for example, forty connecting fastening holes 124, and the forty connecting fastening holes 124 can be divided into two groups, each group includes twenty connecting fastening holes 124 and arranged in a row, and the two groups of connecting fastening holes 124 are spaced apart by a predetermined distance and can be symmetrical to each other. The present invention is not limited thereto, and optionally, the pedal section 110 can be provided with three or more fastening holes 119.

[0087] In some optional embodiments, the connecting pedal section 120 may be provided with two connecting fastening holes 124 arranged at intervals in its length direction, and the pedal section 110 may be provided with more than two fastening holes 119 arranged at intervals along its length direction. The fastening holes 119 may be selectively aligned with the connecting fastening holes 124, and the screw member 130 may be passed through the fastening holes 119 and the connecting fastening holes 124 aligned with each other to connect the pedal section 110 and the connecting pedal section 120.

[0088] In other optional embodiments, the pedal segment 110 is provided with two or more fastening holes 119 arranged at intervals in its length direction, and the connecting pedal segment 120 is provided with two or more connecting fastening holes 124 arranged at intervals in its length direction. The fastening holes 119 can be selectively aligned with the connecting fastening holes 124, and the fasteners 130 can be passed through the aligned fastening holes 119 and the connecting fastening holes 124 to connect the pedal segment 110 and the connecting pedal segment 120.

[0089] As an example, in Figure 1-Figure 30 In the embodiment, the connection fastening hole 124 is provided on the inner side wall of the connection pedal section 120, and the inner side wall 1172 of the pedal section 110 is provided with two fastening holes 119 respectively adjacent to the two ends of the pedal section 110. The fastener 130 is a threaded member. At least one of the first pedal section 110A and the second pedal section 110B is relatively slid with the connection pedal section 120 to adjust the relative position therebetween, so that the fastening hole 119 is aligned with the corresponding connection fastening hole 124 in the inner and outer directions, and the threaded member 130 is sequentially passed through the fastening hole 119 and the connection fastening hole 124 aligned therewith from the inside to the outside, so as to assemble and obtain the pedal 100 with the required length. When adjusting the length of the pedal 100 or disassembling the pedal 100, the threaded member can be removed, and the adjustment and disassembly process is simple and convenient.

[0090] In some embodiments, at least one of the pedal segment 110 and the connecting pedal segment 120 may be provided with a limit to define a maximum sliding distance between the pedal segment 110 and the connecting pedal segment 120 .

[0091] exist Figure 1 and Figure 2 In the illustrated embodiment, the pedal 100 includes three pedal sections 110 and two connecting pedal sections 120. It is to be understood that the present invention is not limited thereto, and the pedal 100 may include any number of pedal sections 110 and connecting pedal sections 120. Advantageously, the pedal 100 includes two pedal sections 110 and one connecting pedal section 120, which not only meets the requirements of most vehicles, but also has a small number of parts, is simple to assemble and disassemble, and has a low cost.

[0092] An example of a pedal 110 is described below, in which the pedal includes two pedal segments 110 and a connecting pedal segment 120 .

[0093] like Figure 3-Figure 26 As shown, the pedal 100 of the embodiment of the present invention includes two pedal segments 110 and a connecting pedal segment 120, the two pedal segments 110 include a first pedal segment 110A and a second pedal segment 110B, the first end 121 of the connecting pedal segment 120 is slidably and detachably connected to the first pedal segment 110A, and the second end 122 of the connecting pedal segment 120 is slidably and detachably connected to the second pedal segment 110B.

[0094] like Figure 3 and Figure 4 As shown, Figure 4 FIG. 1 shows an exploded view of the pedal 100 before assembly, wherein the first pedal section 110A, the second pedal section 110B and the connecting pedal section 120 are arranged along the length direction of the pedal 100. Figure 4 In the figure, the first pedal section 110A is located in front of the second pedal section 110B, and the connecting pedal section 120 is located between the first pedal section 110A and the second pedal section 110B in the front-to-back direction. Therefore, the first end 121 of the connecting pedal section 120 can be called the front end, and the second end 122 of the connecting pedal section 120 can be called the rear end. The "front-to-back" direction refers to the front-to-back direction of the vehicle, the front is the direction close to the front of the vehicle, and the rear is the direction close to the rear of the vehicle.

[0095] The first pedal segment 110A and the second pedal segment 110B can have the same structure, so that the positions of the first pedal segment 110A and the second pedal segment 110B can be interchanged, thereby the first pedal segment 110A and the second pedal segment 110B can be manufactured using molds of the same specifications, making the production and assembly of the pedal 100 more convenient, reducing the number and models of molds for producing the pedal segment 110, and reducing costs.

[0096] It is understood that the number of pedal segments 110 is not limited to two, and the number of connecting pedal segments 120 is not limited to one. Figure 1 and Figure 2 As shown, there are three pedal segments 110 and two connecting pedal segments 120. The structures of the three pedal segments 110 can be the same, that is, the three pedal segments 110 can be manufactured using molds of the same specifications, and the three pedal segments 110 can be interchangeable. The structures of the two connecting pedal segments 120 can also be the same, and the two connecting pedal segments 120 can be interchangeable and can be produced using the same mold, further reducing the number of molds and reducing costs. The number of pedal segments 110 and connecting pedal segments 120 can be set as needed. For example, the longer the length of the pedal 100, the more pedal segments 110 and connecting pedal segments 120 can be. If the number of pedal segments 110 is n, then the number of connecting pedal segments 120 is n-1, where n≥2.

[0097] The relative positions of the first pedal segment 110A, the second pedal segment 110B and the connecting pedal segment 120 are adjustable, and the opposite ends of the first pedal segment 110A and the second pedal segment 110B can be spaced apart or abutted against each other.

[0098] In some embodiments, Figure 5-6 , Figure 9-10As shown, the opposite ends of the first pedal segment 110A and the second pedal segment 110B are spaced apart so that a gap 114 is formed between the opposite ends of the first pedal segment 110A and the second pedal segment 110B, and a portion of the connecting pedal segment 120 is exposed from the gap 114 .

[0099] By sliding the first pedal section 110A and / or the second pedal section 110B relative to the connecting pedal section 120, the length of the gap 114 can be adjusted, thereby adjusting the length of the pedal 100. Specifically, as Figure 5 and Figure 6 As shown, the length of the gap 114 formed between the opposite ends of the first pedal section 110A and the second pedal section 110B is relatively large, the length of the portion exposed from the gap 114 connected to the pedal section 120 is relatively long, and the length of the pedal 100 is relatively long. Fig. 9 and Fig.10 As shown, the length of the gap 114 formed between the first pedal segment 110A and the second pedal segment 110B is relatively small, the length of the portion exposed from the gap 114 and connected to the pedal segment 120 is relatively short, and the length of the pedal 100 is shortened.

[0100] In other embodiments, Fig.11 and Fig.12 As shown, the ends of the first pedal section 110A and the second pedal section 110B facing each other are abutted, so that a gap 113 is formed between the ends of the first pedal section 110A and the second pedal section 110B facing each other. It can be understood that the length of the pedal 100 when the ends of the first pedal section 110A and the second pedal section 110B facing each other are abutted is the shortest length of the assembled pedal 100.

[0101] like Figure 3-Figure 26 As shown, the first pedal segment 110A and the second pedal segment 110B have the same length, and the first pedal segment 110A and the second pedal segment 110B are symmetrical with respect to the gap 113 or the gap 114 therebetween.

[0102] In some embodiments, Figure 3-Figure 26 As shown, the lengths of the first pedal section 110A, the second pedal section 110B and the connecting pedal section 120 are substantially the same. Figure 13-Figure 15 When the pedal 100 is carried and transported, the first pedal segment 110A, the second pedal segment 110B and the connecting pedal segment 120 are disassembled and stacked together, and the ends of the three are basically aligned, which further improves the convenience of carrying and transportation.

[0103] like Figure 5 and Figure 6 , Fig. 9 and Fig.10 , Fig.11 and Fig.12As shown, the connecting pedal section 120 is symmetrical with respect to the gap 113 or the gap 114 between the first pedal section 110A and the second pedal section 110B, that is, the length of the overlapping portion between the connecting pedal section 120 and the first pedal section 110A is equal to the length of the overlapping portion between the connecting pedal section 120 and the second pedal section 110B. Therefore, when the first pedal section 110A and the second pedal section 110B are slid relative to the connecting pedal section 120 to adjust the length of the slide plate 100, the relative sliding distance of the first pedal section 110A is consistent with the relative sliding distance of the second pedal section 110B, so that the pedal 100 has a symmetrical structure, the structure of the pedal 100 is more reasonable, the force is more uniform, and the structural stability is better.

[0104] In other embodiments, the length of the connecting pedal segment 120 is greater than half the length of the first pedal segment 110A and greater than half the length of the second pedal segment 110B.

[0105] In some embodiments, Figure 3-Figure 26 As shown, the pedal section 110 is hollow and has a longitudinal hole (also referred to as a cavity) 116 extending along its length. The first end 121 of the connecting pedal section 120 is slidably fitted in the longitudinal hole 116 of the first pedal section 110A, and the second end 122 of the connecting pedal section 120 is slidably fitted in the longitudinal hole 116 of the second pedal section 110B. Figure 6 and Fig.10 As shown, in the assembled state, the upper surfaces of the first pedal section 110A and the second pedal section 110B of the pedal 100 are both higher than the upper surface of the connecting pedal section 120. When the pedal 100 is disassembled, the fastener 130 is removed, the first end 121 of the connecting pedal section 120 is pulled out from the longitudinal hole 116 of the first pedal section 110A, and the second end 122 of the connecting pedal section 120 is pulled out from the longitudinal hole 116 of the second pedal section 110B.

[0106] The pedal segment 110 is constructed to be hollow, which can reduce the weight of the pedal segment 110 and the materials required for manufacturing, thereby reducing the cost.

[0107] Figure 8 A cross-sectional view of the first pedal segment 110A is shown. Figure 8 As shown, the pedal section 110 includes a top wall 1171, an inner side wall 1172, an outer side wall 1173 and a bottom wall 1174. The top wall 1171 is located above the bottom wall 1174 and is opposite to the bottom wall 1174 in the vertical direction, the inner side wall 1172 is a side wall close to the vehicle body, and the outer side wall 1173 is a side wall away from the vehicle body. The top wall 1171, the inner side wall 1172, the outer side wall 1173 and the bottom wall 1174 jointly define the longitudinal hole 116.

[0108] like Figure 8As shown, the outer contour of the cross section of the pedal segment 110 and the cross-sectional contour of the longitudinal hole 116 are polygons similar to each other, and the pedal segment 110 is a hollow body with a substantially uniform thickness of the peripheral wall. In other words, the wall thicknesses of the top wall 1171, the inner wall 1172, the outer wall 1173 and the bottom wall 1174 of the pedal segment 110 are substantially equal, thereby facilitating the design and production of the mold of the pedal segment 110 and reducing the manufacturing difficulty of the pedal segment 110.

[0109] like Figure 8 As shown, the pedal section 110 further includes an extension 1175 extending from the top wall 1171 and the upper part of the inner side wall 1172. The extension 1175 can increase the size of the pedal section 110 in the inner and outer directions, which helps to enhance the structural strength of the pedal section 110 and facilitates the installation of the pedal 100. A groove 11751 is provided in the extension 1175, and a reinforcement member or the like can be arranged in the groove 11751 to further enhance the structural strength of the pedal section 110 and the pedal 100.

[0110] like Figure 8 As shown, for convenience of stepping, the upper surface of the top wall 1171 is substantially parallel to the horizontal plane. Further, the upper surface of the extension 1175 is flush with the upper surface of the top wall 1171, which can increase the total area of ​​the upper surface of the pedal 100 for stepping.

[0111] like Figure 4 and Figure 8 As shown, a plurality of protrusions 118 are provided on the upper surface of the pedal section 110. The protrusions 118 can be configured as convex strips extending along the length direction of the pedal section 110. The protrusions 118 can increase the roughness of the upper surface of the pedal section 110 and play an anti-slip role. In other embodiments, the protrusions 118 can be other structures, such as bumps, anti-slip grooves, etc.

[0112] In some embodiments, Figure 3-Figure 26 As shown, the connecting pedal section 120 may be hollow, and the connecting pedal section 120 has a connecting longitudinal hole (cavity) 123 extending along its length direction. The connecting pedal section 120 is a hollow structure, which can reduce the weight of the connecting pedal section 120, thereby reducing the overall weight of the pedal 100, while reducing the amount of consumables required for manufacturing the connecting pedal section 120, thereby reducing the manufacturing cost of the connecting pedal section 120.

[0113] Figure 7 A cross-sectional view of the overlapping portion of the second pedal segment 110B and the connecting pedal segment 120 is shown. Figure 7As shown, a part of the connecting pedal section 120 is fitted into the longitudinal hole 116 of the second pedal section 110B. A fastening hole 119 is provided on the inner side wall 1172 of the second pedal section 110B, and the fastening hole 119 is a through hole penetrating the inner side wall 1172. A connecting fastening hole 124 is provided on the side wall of the connecting pedal section 120 opposite to the inner side wall 1172, and the connecting fastening hole 124 is a threaded hole penetrating the side wall. The fastening hole 119 of the second pedal section 110B is aligned with the connecting fastening hole 124 of the connecting pedal section 120, and the screw member (fastener 130) passes through the fastening hole 119 of the second pedal section 110B and the connecting fastening hole 124 of the connecting pedal section 120, and is threadedly fitted with the connecting fastening hole 124, thereby fastening the second pedal section 110B to the connecting pedal section 120. In addition, a countersunk hole is provided at the end of the fastening hole 119 to hide the head of the screw member.

[0114] like Figure 7 As shown, the outer contour of the cross section of the connecting pedal section 120, the contour of the cross section of the connecting longitudinal hole 123, and the contour of the cross section of the longitudinal hole 116 of the pedal section 110 are constructed as polygons similar to each other. The outer contour of the cross section of the connecting pedal section 120 and the contour of the cross section of the connecting longitudinal hole 123 are constructed as polygons similar to each other, so that the connecting pedal section 120 is constructed as a hollow body with a substantially uniform peripheral wall thickness similar to the pedal section 110, thereby facilitating the design and production of the mold of the connecting pedal section 120 and reducing the manufacturing difficulty of the connecting pedal section 120. The outer contour of the cross section of the connecting pedal section 120 and the contour of the cross section of the longitudinal hole 116 of the pedal section 110 are constructed as polygons similar to each other, so that the structural shape of the connecting pedal section 120 is better adapted to the longitudinal hole 116 of the pedal section 110. In addition, the pedal section 110 and the connecting pedal section 120 are both constructed as polygonal prisms. Compared with the plate-like structure, the prism structure is not easy to deform and has a large structural strength.

[0115] like Figure 7 As shown, the outer circumferential surface of the connecting pedal section 120 and the inner circumferential surface of the longitudinal hole 116 of the pedal section 110 can be slidably fitted so as to form a stable limiting relationship between the pedal section 110 and the connecting pedal section 120, thereby improving the structural stability of the pedal 100 and avoiding abnormal noise and looseness caused by excessive gap between the pedal section 110 and the connecting pedal section 110.

[0116] In some embodiments, Figure 7 and Figure 8 As shown, the cross section of each of the longitudinal hole 116 of the pedal section 110 and the connecting longitudinal hole 123 connecting the pedal section 120 includes a rectangular hole portion and a triangular hole portion or a trapezoidal hole portion located outside the rectangular hole portion. The "outer side" refers to the side away from the vehicle body, and the side close to the vehicle body is the inner side.

[0117] As an example, Figure 8 As shown, the longitudinal hole 116 of the pedal section 110 includes a first rectangular hole portion 1161 and a first trapezoidal hole portion 1162, and the first trapezoidal hole portion 1162 is located outside the first rectangular hole portion 1161. The first rectangular hole portion 1161 is connected with the first trapezoidal hole portion 1162 to form a longitudinal hole 116 with an inverted trapezoidal cross-sectional shape. The bottom wall 1174 includes a flat bottom wall section 11741 and an inclined bottom wall section 11742, the flat bottom wall section 11741 is parallel to the top wall 1171, and the inclined bottom wall section 11742 extends upward and outward from the flat bottom wall section 11741, that is, the inclined bottom wall section 11742 extends outward from the flat bottom wall section 11741 while being inclined toward the direction close to the top wall 1171, and forms an angle with the flat bottom wall section 11741. It can be understood that the upper surface of the flat bottom wall section 11741 is the bottom wall surface of the first rectangular hole portion 1161 of the longitudinal hole 116, and the upper surface of the inclined bottom wall section 11742 is the bottom wall surface of the first trapezoidal hole portion 1162. Therefore, the thickness of the side of the pedal section 110 close to the vehicle body is greater than the thickness of the side away from the vehicle body, that is, the height of the inner wall 1172 is greater than the height of the outer wall 1173, so that it is convenient to open the fastening hole 119 on the inner wall 1172, and after the pedal 100 is installed on the vehicle body, the structure is more stable, and the fastening hole 119 is hidden in appearance, making the vehicle appearance more beautiful.

[0118] like Figure 7 As shown, the connecting longitudinal hole 123 includes a second rectangular hole portion 1231 and a second trapezoidal hole portion 1232, and the second trapezoidal hole portion 1232 is located outside the second rectangular hole portion 1231. The second rectangular hole portion 1231 and the second trapezoidal hole portion 1232 are connected to form a connecting longitudinal hole 123 with an inverted trapezoidal cross-sectional shape, and the cross-sectional profile of the connecting longitudinal hole 123 is similar to the cross-sectional profile of the longitudinal hole 116. As a result, the thickness of the side of the connecting pedal section 120 close to the vehicle body is greater than the thickness of the side away from the vehicle body, so that it is convenient to open the connecting fastening hole 124 on its inner side wall, and after the pedal 100 is installed on the vehicle body, the structural strength is large, and the connecting fastening hole 124 is hidden in appearance, making the vehicle appearance more beautiful.

[0119] In some embodiments, Figure 16-Figure 20 as well as Figure 22-26 As shown, the pedal 100 further includes a reinforcing strip 160 and a locking strip 170. Fig. 20 As shown, the pedal section 110 includes a top wall 1171, an inner side wall 1172, an outer side wall 1173, a bottom wall 1174, and an extension portion 1175 extending from the top wall 1171 and the upper portion of the inner side wall 1172. The top wall 1171 is located above the bottom wall 1174 and is opposite to the bottom wall 1174 in the vertical direction, the inner side wall 1172 is a side wall relatively close to the vehicle body, and the outer side wall 1173 is a side wall away from the vehicle body. Fig. 20As shown, a groove 11751 is provided in the extension portion 1175, the reinforcing strip 160 is fitted in the groove 11751 of the adjacent pedal section 110, and the locking strip 170 is connected to the reinforcing strip 160 through a screw member 171 and is fitted to the inner side wall 1172. The reinforcing strip 160 and the locking strip 170 further improve the structural strength of the pedal 100 and improve the integrity of the pedal 100.

[0120] As an example, Figure 16-Figure 20 As shown, the first pedal section 110A and the second pedal section 110B both have an extension 1175, and the bottom of the extension 1175 of the first pedal section 110A and the second pedal section 110B are both provided with a groove 11751, the cross-sectional shape of the groove 11751 is T-shaped, and the cross-sectional shape of the reinforcing strip 160 is T-shaped to match the groove 11751. Fig.18 and 19 As shown, one end of the reinforcing strip 160 extends into the groove 11751 of the extension portion 1175 of the first pedal section 110A and can slide relative to the groove 11751 of the first pedal section 110A, and the other end of the reinforcing strip 160 extends into the groove 11751 of the extension portion 1175 of the second pedal section 110B and can slide relative to the groove 11751 of the second pedal section 110B. The reinforcing strip 160 is provided with a plurality of threaded holes 161 arranged at intervals in the length direction thereof. The locking strip 170 is located below the reinforcing strip 160. Figure 16-Figure 20 In the embodiment shown, the locking strip 170 is in an inverted L shape, and the locking strip 170 is provided with a plurality of mounting holes 172 arranged at intervals in the length direction thereof, and the plurality of mounting holes 172 are aligned one by one with the plurality of threaded holes 161 in the vertical direction, and the screw member 171 passes through the mounting holes 172 and the threaded holes 161 in sequence from bottom to top and cooperates with the threaded holes 161 to connect the locking strip 170 with the reinforcing strip 160. Fig. 20 As shown, the outer side surface of the locking strip 170 is in contact with the inner wall surface 1172 of the pedal section 110. With the cooperation of the reinforcing strip 160 and the locking strip 170, the connection between the first pedal section 110A, the second pedal section 110B and the connecting pedal section 120 is more stable, and the integrity of the pedal 100 is better.

[0121] like Fig.18 and 20 As shown, the reinforcing strip 160 and the locking strip 170 span the gap or gap between the first pedal section 110A and the second pedal section 110B. Optionally, a plurality of through holes arranged along the length direction of the locking strip 170 can be provided. When assembling the pedal 100, the fastener 130 passes through the through hole, the fastening hole 119 and the connecting fastening hole 124, thereby further improving the integrity and structural strength of the pedal 100.

[0122] In some embodiments, Figure 21-26 As shown, the pedal 100 further includes a decorative cover plate 140, which is used to cover the gap 113 or the gap 114 between the adjacent pedal sections 110, so as to prevent the gap 113 or the gap 114 between the adjacent pedal sections 110 from being observed from the outside, thereby making the pedal 100 more beautiful in appearance. Specifically, the ends of the first pedal section 110A and the second pedal section 110B facing each other are abutted, and the gap 113 is formed between the ends of the first pedal section 110A and the second pedal section 110B facing each other, and the decorative cover plate 140 covers the gap 113. The ends of the first pedal section 110A and the second pedal section 110B facing each other are spaced apart, and the gap 114 is formed between the ends of the first pedal section 110A and the second pedal section 110B facing each other, and a part of the connecting pedal section 120 is exposed from the gap 114, and the decorative cover plate 140 covers the gap 114, that is, covers the exposed part of the connecting pedal section 120. The decorative cover 140 may be engaged and / or screwed to the first pedal section 110A and the second pedal section 110B. Optionally, the decorative cover 140 may be connected to the connecting pedal section 120 by screws and / or engaged and / or screwed to the first pedal section 110A and the second pedal section 110B.

[0123] In some optional embodiments, such as Figure 21-26 As shown, the decorative cover plate 140 is an integrated structure. The integrated decorative cover plate 140 is easy to manufacture and has a low cost.

[0124] In other optional embodiments, the decorative cover plate 140 includes a plurality of cover plate strips, which are mutually abutted or connected in the length direction of the connecting pedal section 120. By changing the number of cover plate strips, the length of the decorative cover plate 140 can be changed, and the length of the decorative cover plate 140 can be flexibly adjusted according to the length of the gap 114, so that the decorative cover plate 140 can better cover and hide the gap 114, improve the flexibility of the decorative cover plate 140 in practical application, and make up for the height difference between the upper surface of the first pedal section 110A and the second pedal section 110B and the upper surface of the connecting pedal section 120.

[0125] In some optional embodiments, the length of the decorative cover plate 140 is greater than the length of the gap 114, and the decorative cover plate 140 covers the gap 114 and a portion of the first pedal segment 110A and / or the second pedal segment 110B. Fig.21 as well as Figure 22-Figure 26 In the illustrated embodiment, the decorative cover 140 covers the gap 114 , and both ends of the decorative cover 140 extend forward and backward from both ends of the gap 114 , with one portion covering the first pedal section 110A and the other portion covering the second pedal section 110B.

[0126] like Fig.26As shown, the decorative cover 140 includes a top plate 141, an inner flange 142 and an outer flange 143. The top plate 141 covers the gap 113 or the gap 114. The inner flange 142 extends downward from the inner edge of the top plate 141 (close to the edge of the vehicle body 310) and then extends outward and clamps the extension portion 1175 of the first pedal segment 110A and the extension portion 1175 of the second pedal segment 110B. The outer flange 143 extends downward from the outer edge of the top plate 141 (away from the edge of the vehicle body 310) and then extends inward and clamps the bottom wall 1174 of the first pedal segment 110A and the bottom wall 1174 of the second pedal segment 110B. The setting of the decorative cover plate 140 makes the pedal 100 more beautiful in appearance. At the same time, the covering of the inner flange 142 and the outer flange 143 makes the decorative cover plate 140 "stuck" on the first pedal section 110A and the second pedal section 110B, and plays a role in enhancing the structural strength of the pedal 100.

[0127] As an example, Figure 22-Figure 26 As shown, the decorative cover plate 140 includes a top plate 141, an inner flange 142 connected to the inner edge of the top plate 141, and an outer flange 143 connected to the outer edge of the top plate 141. The top plate 141 covers the top of the gap 114, and extends forward and backward from both sides of the gap 114, respectively, covering a part of the first pedal section 110A and a part of the second pedal section 110B. The inner flange 142 of the decorative cover plate 140 forms a edging structure to cover a part of the extension 1175 of each of the first pedal section 110A and the second pedal section 110B, and the outer flange 143 of the decorative cover plate 140 forms a edging structure to cover a part of the outer side of each of the first pedal section 110A and the second pedal section 110B. As a result, the gap 114 is completely hidden in appearance.

[0128] In some other optional embodiments, the length of the decorative cover plate 140 is equal to the length of the gap 114. The decorative cover plate 140 is arranged on the connecting pedal section 120 to compensate for the height difference between the pedal section 110 and the connecting pedal section 120. The two opposite ends of the decorative cover plate 140 in the length direction of the connecting pedal end 120 are respectively against the first pedal section 110A and the second pedal section 110B. By arranging the decorative cover plate 140 in the gap 114, the upper surface of the decorative cover plate 140 is substantially flush with the upper surface of the first pedal section 110A and the upper surface of the second pedal section 110B, so that the pedal 100 has a better feel in use.

[0129] In some embodiments, the pedal 100 further includes a head 150. The pedal sections 110 of the pedal 100 include two end pedal sections 115. The end pedal sections 115 refer to the pedal sections 110 located at the two ends of the pedal 100. It can be understood that when the pedal 100 includes two pedal sections 110, the first pedal section 110A and the second pedal section 110B are also referred to as two end pedal sections 115. The end pedal section 115 has a free end 1150A and a connecting end 1150B. The connecting end 1150B is connected to the connecting pedal section 120. The head 150 is detachably mounted on the free end 1150A of the end pedal section 115, or the head 150 is formed integrally with the end pedal section 115. The head 150 seals the two ends of the pedal 100 to make the pedal 100 more beautiful in appearance.

[0130] Specifically, Figure 21-26 As shown, the pedal 100 includes two heads 150, namely a first head 150A and a second head 150B. A portion of the first head 150A is inserted into the opening of the free end of the longitudinal hole 116 of the first pedal segment 110A to block the opening of the free end of the longitudinal hole 116 of the first pedal segment 110A, and the other portion of the first head 150A is located outside the longitudinal hole 116, and the upper surface height of the other portion of the first head 150A is basically consistent with the upper surface height of the first pedal segment 110A.

[0131] A portion of the second end cap 150B is inserted into the opening of the free end of the longitudinal hole 116 of the second pedal segment 110B to block the opening of the free end of the longitudinal hole 116 of the second pedal segment 110B, and another portion of the second end cap 150B is located outside the longitudinal hole 116, and the upper surface height of the other portion of the second end cap 150B is substantially consistent with the upper surface height of the second pedal segment 110B. In addition, the first pedal segment 110A and the second pedal segment 110B are symmetrical with respect to the gap 113 or the gap 114 therebetween, and the first end cap 150A and the second end cap 150B are symmetrical with respect to the gap 113 or the gap 114.

[0132] exist Figure 1-Figure 26 In the illustrated embodiment, the pedal section 110 is hollow and has a longitudinal hole 116 extending along its length, the connecting pedal section 120 is hollow and has a connecting longitudinal hole 123 extending along its length, the first end 121 of the connecting pedal section 120 slides in the longitudinal hole 116 of the first pedal section 110A, and the second end 122 of the connecting pedal section 120 slides in the longitudinal hole 116 of the second pedal section 110A.

[0133] In other embodiments, Figure 27-Figure 30As shown, the pedal section 110 is hollow and has a longitudinal hole 116 extending along its length direction, the connecting pedal section 120 is hollow and has a connecting longitudinal hole 123 extending along its length direction, and the ends of the first pedal section 110A and the second pedal section 110B opposite to each other are slidably fitted in the connecting longitudinal hole 123. That is, the end of the first pedal section 110A close to the second pedal section 110B extends into the opening of the first end 121 of the connecting pedal section 120 and is slidable along the connecting longitudinal hole 123, and the end of the second pedal section 110B close to the first pedal section 110A extends into the opening of the second end 122 of the connecting pedal section 120 and is slidable along the connecting longitudinal hole 123. Both the pedal section 110 and the connecting pedal section 120 are constructed with hollow structures, which can reduce the overall weight and material consumption of the pedal 100, and further facilitate handling and transportation. In this embodiment, the fastening of the first pedal segment 110A and the second pedal segment 110B to the connecting pedal segment 120 may be achieved in the same manner as in the above-mentioned embodiment.

[0134] It can be understood that in these embodiments, the upper surfaces of the first pedal segment 110A and the second pedal segment 110B are both lower than the upper surface of the connecting pedal segment 120 .

[0135] like Fig.28 As shown, the length of the portion of the first pedal section 110A extending into the connecting longitudinal hole 123 and the length of the portion of the second pedal section 110B extending into the connecting longitudinal hole 123 are both shorter, the distance between the ends of the first pedal section 110A and the second pedal section 110B facing each other is larger, and the length of the pedal 100 is longer. Fig.29 As shown, the first pedal segment 110A and the second pedal segment 110B continue to extend inwardly into the connecting longitudinal hole 123, so that the distance between the opposite ends of the first pedal segment 110A and the second pedal segment 110B is reduced, and the length of the pedal 100 is shortened.

[0136] like Fig.28 and 29 As shown, the length of the portion of the first pedal segment 110A extending into the connecting longitudinal hole 123 is equal to the length of the portion of the second pedal segment 110B extending into the connecting longitudinal hole 123, and the portion of the first pedal segment 110A located outside the connecting longitudinal hole 123 and the portion of the second pedal segment 110B located outside the connecting longitudinal hole 123 are symmetrical relative to the connecting pedal segment 120, so that the pedal 100 as a whole is constructed as a symmetrical structure.

[0137] like Fig.30As shown, the outer contour of the cross section of the pedal segment 110, the contour of the cross section of the longitudinal hole 116, and the cross section contour of the connecting longitudinal hole 123 are constructed as polygons similar to each other. The outer contour of the cross section of the pedal segment 110 and the contour of the cross section of the longitudinal hole 116 are constructed as polygons similar to each other, so that the pedal segment 110 is constructed as a hollow body with a substantially uniform thickness of the peripheral wall, which facilitates the manufacture of the pedal segment 110. The outer contour of the cross section of the pedal segment 110 and the cross section contour of the connecting longitudinal hole 123 are constructed as polygons similar to each other, and the structural shape of the pedal segment 110 is better adapted to the connecting longitudinal hole 123 of the connecting pedal segment 120. In addition, the pedal segment 110 and the connecting pedal segment 120 are both constructed as polygonal prisms. Compared with a plate-like structure, a polygonal prism is not easily deformed and has a stronger structural strength.

[0138] like Fig.30 As shown, the outer circumferential surface of the pedal segment 110 and the inner circumferential surface of the connecting longitudinal hole 123 can be slidably fitted together to form a stable limiting relationship between the pedal segment 110 and the connecting pedal segment 120, thereby improving the structural stability of the pedal 100 and avoiding loose fit and abnormal noise between the pedal segment 110 and the connecting pedal segment 120 due to an excessively large gap between the two.

[0139] In other embodiments, one of the pedal section 110 and the connecting pedal section 120 is provided with a slide groove or a slide hole, and the end of the other of the pedal section 110 and the connecting pedal section 120 can be slidably fitted in the slide groove or the slide hole, thereby realizing a slidable and detachable connection between the first pedal section 110A and the second pedal section 110B and the connecting pedal section 120. For example, the connecting pedal section 120 is provided with a slide groove opening downward, and the extension direction of the slide groove is the same as the extension direction of the connecting pedal section 120. The slide groove is open at both ends of the connecting pedal section 120 to form an opening, and the opposite ends of the two pedal sections 110 adjacent to the connecting pedal section 120 extend into the slide groove from the openings at both ends of the slide groove, respectively, and can slide relative to the slide groove. For another example, a sliding hole extending along the length direction of the connecting pedal section 120 is provided in the connecting pedal section 120, and the sliding hole is open at both ends of the connecting pedal section 120 to form openings, and the opposite ends of the two pedal sections 110 adjacent to the connecting pedal section 120 extend into the sliding groove from the openings at both ends of the sliding hole respectively and can slide relative to the sliding hole.

[0140] Next, the pedal device 200 according to the embodiment of the present invention will be described.

[0141] like Figure 31-Figure 34 As shown, the pedal device 200 includes a connecting rod mechanism 210 and a pedal. The pedal is the pedal 100 in the above embodiment. The pedal 100 is connected to the connecting rod mechanism 210 to be driven by the connecting rod mechanism 210 to move between an extended position and a retracted position.

[0142] Fig.35 and Fig.36 FIG. 3 shows a vehicle 300 according to an embodiment of the present invention. Fig.35 and Fig.36 As shown, the vehicle 300 includes a vehicle body 310 and a pedal device 200, wherein the pedal device 200 is installed on at least one side of the vehicle body 310 and / or the rear of the vehicle body 310. Fig.35 As shown, the length of the pedal 100 is relatively short. Fig.36 As shown, the length of the pedal 100 is relatively long.

[0143] like Figure 31-Figure 34 As shown, the link mechanism 210 includes a mounting seat 211, a pedal seat 212, and an arm assembly 213. The pedal 100 is mounted on the pedal seat 212, and the mounting seat 211 is used to be mounted on the bottom surface of the vehicle body 310. The arm assembly 213 is connected between the mounting seat 211 and the pedal seat 212 to drive the pedal 100 to move between the extended position and the retracted position. For example, the arm assembly 213 can be pivotally connected to the mounting seat 211 and the pedal seat 212 respectively, and the arm assembly 213 drives the pedal 100 to move between the extended position and the retracted position under the drive of a driving device (such as a motor, more advantageously, a DC brushless motor).

[0144] In some embodiments, in the retracted position, the pedal 100 is against the lower edge of the side of the vehicle body 310. For example, the pedal 100 is oriented in a vertical direction and is against the lower edge of the side of the vehicle body 310, so that the pedal 100 covers the lower edge of the vehicle body 310 to protect the lower edge of the vehicle body 310.

[0145] In other embodiments, in the retracted position, the pedal 100 is tilted against the junction of the bottom surface of the vehicle body 310 and the side surface of the vehicle body 310. In other words, the pedal 100 is tilted relative to the vehicle body 310 and is against the junction of the bottom surface of the vehicle body 310 and the side surface of the vehicle body 310, so that the pedal 100 can cover the outer edge of the bottom surface of the vehicle body 310 and the lower edge of the side surface of the vehicle body 310. Therefore, the pedal 100 can be used as a bumper of the vehicle and play a protective function to protect the vehicle body 310 to prevent the vehicle 300 from being hit or scratched.

[0146] In some embodiments, there are two connecting rod mechanisms 210 and they are arranged at intervals along the length direction of the pedal 100. Fig.31 As shown, the two link mechanisms 210 are arranged at intervals in the front-to-rear direction and are respectively connected to the inner sides of the first pedal section 110A and the second pedal section 110B.
