In addition, it should be noted that this specification describes many features.

[0036] Example embodiments will now be described more fully with reference to the accompanying drawings. However, the example embodiments can be implemented in various forms and should not be construed as limited to the examples set forth herein; rather, these example embodiments are provided so that the description of the present application will be more complete and comprehensive, and the concept of the example embodiments will be fully conveyed to those skilled in the art. The drawings are only schematic illustrations of the present application and are not necessarily drawn to scale. The same reference numerals in the drawings denote the same or similar parts, and thus their repeated description will be omitted.

[0037] The preferred embodiments of the present application will be further elaborated in detail below in conjunction with the drawings of this specification.

[0038] Refer to Figure 1 and Figure 2As shown in the figure, the present application provides a step assembly, which is applied to a vehicle, mainly to a heavy-duty vehicle. When a vehicle is mounted, some electrical connections need to be made. Generally, a heavy-duty vehicle is heavy and has a high vehicle height. To facilitate electrical connection, a step assembly is provided. Users can board the electrical connection position of the vehicle through the step assembly. The step assembly includes: a support frame 10, a step beam 20, a first pipe beam 30, and a second pipe beam 40; the support frame 10, the step beam 20, the first pipe beam 30, and the second pipe beam 40 are connected end to end in sequence to form a closed-loop force-bearing structure. Specifically, the step beam 20 is disposed on one side of the support frame 10; one end of the first pipe beam 30 is directly connected to the step beam 20, and the other end is directly connected to the support frame 10; one end of the second pipe beam 40 is directly connected to the step beam 20, and the other end is directly connected to the support frame 10. In this closed-loop force-bearing structure, the first pipe beam 30 and the second pipe beam 40 do not extend out side branch structures, and the overall structure is more concise.

[0039] In the technical solution of this embodiment, one end of the support frame 10 and the step beam 20 is connected by the first pipe beam 30, and the other end of the support frame 10 and the step beam 20 is connected by the second pipe beam 40. And the first pipe beam 30 is directly connected to the step beam 20 and the support frame 10, and the second pipe beam 40 is also directly connected to the step beam 20 and the support frame 10. There are no other structural components extending in the middle, and the structure is more concise. In addition, from the overall connection structure, the support frame 10, the first pipe beam 30, the step beam 20, and the second pipe beam 40 are connected in sequence to form a ring structure. The ring structure forms a closed and firm component, and the overall structure is more stable.

[0040] Refer to Figure 3 As shown in the figure, in one embodiment of the present application, the included angle between the first pipe beam 30 and the step beam 20 is θ1, and the included angle between the second pipe beam 40 and the step beam 20 is θ2, where both θ1 and θ2 are obtuse angles. It can be seen from this that the first pipe beam 30 and the second pipe beam 40 are inclined in directions away from each other. Further, the connection position between the first pipe beam 30 and the step beam 20 has a first action line 310, and the first action line 310 is along the pipe body direction of the first pipe beam 30. It can also be understood that the first action line 310 is the action line of the tensile force of the first pipe beam 30 on the step beam 20. The connection position between the second pipe beam 40 and the step beam 20 has a second action line 410, and the second action line 410 is along the pipe body direction of the second pipe beam 40. It can also be understood that the second action line 410 is the action line of the tensile force of the second pipe beam 40 on the step beam 20. The first action line 310 and the second action line 410 intersect and meet at a point in the distance. The support frame 10, the first pipe beam 30, and the second pipe beam 40 are equivalent to constituting a triangular force-applying structure, and the force of the triangle is more stable, further improving the fixation of the support frame 10 on the step beam 20.

[0041] In the above embodiments, the angular range of the included angle θ1 between the first pipe beam 30 and the step beam 20 is: 90° < θ1 ≤ 110°. The angular range of the included angle θ2 between the second pipe beam 40 and the step beam 20 is: 90° < θ2 ≤ 110°. Within this angular range, it can be ensured that the first pipe beam 30 and the step beam 20, as well as the second pipe beam 40 and the step beam 20, are inclined to each other. The angle of θ1 can be 91°, 92°, 93°, 94°, 95°, 96°, 97°, 98°, 99°, 100°, 101°, 102°, 103°, 104°, 105°, 106°, 107°, 108°, 109 or 110°, etc. The angle of θ2 can be 91°, 92°, 93°, 94°, 95°, 96°, 97°, 98°, 99°, 100°, 101°, 102°, 103°, 104°, 105°, 106°, 107°, 108°, 109 or 110°, etc.

[0042] To reduce the mutual interference between the step beam 20 and the support frame 10, the first pipe beam 30 further includes a first connection section 31 and a first fixing section 32. One end of the first connection section 31 is connected to the step beam 20, and the other end is connected to the first fixing section 32. The end of the first fixing section 32 away from the first connection section 31 is connected to the support frame 10. The first fixing section 32 and the first connection section 31 are arranged at an included angle, and the included angle is defined as α, then it satisfies: 80° ≤ α ≤ 100°; thus, it can be seen that the included angle between the first fixing section 32 and the first connection section 31 is relatively large, ensuring that the step beam 20 and the support frame 10 are spaced apart by a certain distance.

[0043] The second pipe beam 40 further includes a second connection section 41 and a second fixing section 42. One end of the second connection section 41 is connected to the step beam 20, and the other end is connected to the second fixing section 42. The end of the second fixing section 42 away from the second connection section 41 is connected to the support frame 10. The second fixing section 42 and the second connection section 41 are arranged at an included angle, and the included angle is defined as β, then it satisfies: 80° ≤ β ≤ 100°. The included angle between the second fixing section 42 and the second connection section 41 is also relatively large, further ensuring that the step beam 20 and the support frame 10 are spaced apart by a certain distance. The angles of the α angle and the β angle can be the same, mainly to ensure the horizontal state of the step beam 20 and ensure that the distances from both ends to the support frame 10 are equal. Among them, the angle of the α angle can be 80°, 81°, 82°, 83°, 84°, 85°, 86°, 87°, 88°, 89°, 90°, 91°, 92°, 93°, 94°, 95°, 96°, 97°, 98°, 99° or 100, etc. Among them, the angle of the β angle can be 80°, 81°, 82°, 83°, 84°, 85°, 86°, 87°, 88°, 89°, 90°, 91°, 92°, 93°, 94°, 95°, 96°, 97°, 98°, 99° or 100, etc.

[0044] Further, the first connecting section 31 has a first action line 310 extending along the pipe body, and the second connecting section 41 has a second action line 410 extending along the pipe body. The first action line 310 and the second action line 410 intersect, and the included angle between the first action line 310 and the second action line 410 is γ, and 75° ≤ γ < 90° is satisfied. The included angle γ between the first action line 310 and the second action line 410 is between 75° and 90°, so as to ensure their intersection. Subsequently, it is ensured that the first action line 310 and the second action line 410 meet at a point in the distance, improving the force stability of the support frame 10, the first pipe beam 30, and the second pipe beam 40.

[0045] In addition, it can be known that the first connecting section 31 and the second connecting section 41 are inclined away from each other. In this way, a space with a wider upper part and a narrower lower part is formed between the support frame 10 and the step beam 20. When a user climbs the step beam 20, the upper part is wider, providing enough space to insert the foot. The lower part is narrower, which can save the length of the step beam 20 and thus save materials.

[0046] Refer to Figure 4 As shown, in order to better and stably fix the step beam 20 on the support frame 10, the step assembly includes a fixing piece 50. The fixing piece 50 includes a receiving portion 510 and two positioning portions 510. The receiving portion 510 is formed with an arc-shaped groove 511. The two positioning portions 510 are respectively arranged on both sides of the arc-shaped groove 511 of the receiving portion 510. The fixing piece 50 is arranged at the bottom of the support frame 10. One end of the first fixing section 32 far from the first connecting section 31 is inserted into the arc-shaped groove 511, and the length of the first fixing section 32 is redundantly set. When fixing the first pipe beam 30, the first fixing section 32 of the first pipe beam 30 extends into the arc-shaped groove 511 and is fastened to the bottom of the support frame 10 through the fixing piece 50. The arc-shaped groove 511 can clamp the first fixing section 32 to complete the fixing of the first pipe beam 30. In addition, the length of the first fixing section 32 is redundantly set and the length of the first fixing section 32 is longer, so that the first fixing section 32 can be telescoped in the arc-shaped groove 511. Through the telescoping of the first fixing section 32, the distance between the step beam 20 and the support frame 10 can be adjusted to avoid interference between the two. It can also ensure that the distances between the step beam 20 and the outer surface of the support frame 10 are equal, avoiding the inclination of the step beam 20.

[0047] Further, one end of the second fixing section 42 away from the second connecting section 41 is connected to the side wall surface of the support frame 10. The second fixing section 42 includes a bending portion 421 and a flat portion 422. One end of the bending portion 421 is connected to the second connecting section 41, and the other end of the bending portion 421 is connected to the flat portion 422. The flat portion 422 has two flat surfaces arranged oppositely, and the surfaces of the flat surfaces are perpendicular to the plane where the tread beam 20 is located. A first elongated hole 422a is formed on the surface of the flat portion 422, and the length direction of the first elongated hole 422a is parallel to the plane where the tread beam 20 is located. The side wall surface of the support frame 10 and the flat surface of the flat portion 422 are parallel, so that the two surfaces can be better attached together. A larger contact area can make the flat portion 422 and the support frame 10 contact better. Moreover, by arranging the length direction of the first elongated hole 422a in parallel, the expansion and contraction of the second fixing section 42 can be adjusted back and forth. For example, by fixing a screw in the first elongated hole 422a and fixing the relative position of the screw and the support frame 10, and moving the second fixing section 42, the screw can be fixed at different positions in the first elongated hole 422a.

[0048] As can be seen from the above, both the first fixing section 32 and the second fixing section 42 can achieve expansion and contraction, so as to ensure that the distances between the two ends of the tread beam 20 and the outer surface of the support frame 10 are equal. Generally, the second fixing section 42 is fixed first, and then the first fixing section 32 is fixed.

[0049] In the above embodiment, a second elongated hole 521 is formed on the surface of the positioning portion 510, and the length direction of the second elongated hole 521 is orthogonal to the length direction of the first elongated hole 422a. For example, the positioning portion 510 is also fixed by a screw. By positioning the screw at different positions in the second elongated hole 521, the first pipe beam 30 can be fixed at different positions on the support frame 10. Thus, the support frame 10 can adapt to the installation of tread beams 20 with different widths.

[0050] Refer to Figure 5 As shown, when fixing the tread beam 20, the first pipe beam 30 and the second pipe beam 40, a first clamping opening 210 is formed at one end of the tread beam 20, and a second clamping opening 220 is formed at the other end. The inner wall surface of the first clamping opening 210 is adapted to the outer wall surface of the first pipe beam 30, and one end of the first pipe beam 30 is arranged in the first clamping opening 210; the inner wall surface of the second clamping opening 220 is adapted to the outer wall surface of the second pipe beam 40, and one end of the second pipe beam 40 is arranged in the second clamping opening 220. One end of the first pipe beam 30 can be inserted into the first clamping opening 210, and the first pipe beam 30 can be temporarily clamped through the first clamping opening 210. Similarly, one end of the second pipe beam 40 can be inserted into the second clamping opening 220, and the second pipe beam 40 can be temporarily clamped through the second clamping opening 220. Thus, it is convenient to fix the first pipe beam 30 and the second pipe beam 40 to the tread beam 20, and the fixing method can be selected as welding.

[0051] When the user uses the step assembly, to make the stepping more stable, the step beam 20 includes a beam body and a stepping surface. The stepping surface is arranged on the upper surface of the beam body, and stamping holes 230 are arranged on the surface of the stepping surface. The circumferential wall of the stamping hole 230 protrudes from the surface of the stepping surface. The protruding stamping holes 230 can increase the friction force on the bottom surface of the user's shoes and avoid the phenomenon of slipping when the user steps. In addition, setting the stamping holes 230 can also reduce the weight of the step assembly.

[0052] It should be noted that generally, the contact position between the first pipe beam 30 and the support frame 10 is located at the middle position of the support frame 10, and the second pipe beam 40 is connected to the side wall surface of the support frame 10. This can save the other half of the position for installing other devices. In order to effectively save space and reduce the space occupied by the step beam 20, if the length of the step beam 20 is L1 and the length of the support frame 10 is L2, then: 3 / 10 ≤ L1 / L2 ≤ 5 / 10. It can be seen from this that the length of the step beam 20 occupies at most half of the length of the support frame 10. And in order to save space, the support frame 10, the step beam 20, the first pipe beam 30 and the second pipe beam 40 are connected end to end in sequence. In the formed closed-loop structure, the upper width is 320 mm and the lower width is 190 mm.

[0053] This application also provides a vehicle. The vehicle includes a vehicle frame and a step assembly. The vehicle frame has a battery installation position. The support frame 10 includes a pedal 11 and a surrounding plate 12. The surrounding plate 12 is arranged around the pedal 11, and the support frame 10 covers the battery installation position. A battery for starting the vehicle is arranged at the battery installation position. The support frame 10 is buckled on the battery and can also provide good protection for the battery. The support frame 10 is also called a battery box.

[0054] Among them, the specific implementation manner of the vehicle can refer to the embodiment of the step assembly and will not be elaborated here.

[0055] Although this application has been described with reference to several typical embodiments, it should be understood that the terms used are illustrative and exemplary rather than restrictive. Since this application can be specifically implemented in multiple forms without departing from the spirit or essence of the invention, it should be understood that the above embodiments are not limited to any of the foregoing details, but should be broadly interpreted within the spirit and scope defined by the appended claims. Therefore, all changes and modifications falling within the scope of the claims or their equivalents should be covered by the appended claims.
