[0046] 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.

[0047] like Figure 1 and Figure 2 As shown, the frame oblique tube assembly of the embodiment of the present invention includes a frame 1, a front blocking member 2 and an oblique tube 3.

[0048] The frame 1 can be integrally formed. For example, the frame 1 can be made of metal and can be integrally formed by sheet metal stamping or casting. The frame 1 includes a pedal 11, a first side plate 12 and a second side plate 13. The first side plate 12 and the second side plate 13 are arranged in a width direction ( Figure 1 The first side plate 12 and the second side plate 13 are relatively arranged in the left and right directions and are both located below the pedal 11. The first side plate 12 and the second side plate 13 are both substantially located in the vertical plane. The first side plate 12 can be connected to the left side of the pedal 11, and the second side plate 13 can be connected to the right side of the pedal 11.

[0049] The upper surface of the pedal 11 is a plane, and when in use, the pedal 11 can be stepped on by the user. The first side plate 12 and the second side plate 13 can meet the needs of shielding and protecting the left and right sides, and have a protective effect on the components in the frame 1. Secondly, the first side plate 12 and the second side plate 13 can also have a load-bearing effect, so that the weight of the human body can be first transferred to the pedal 11, and then can be decomposed and transmitted downward through the first side plate 12 and the second side plate 13, meeting the need for support.

[0050] It is understandable that, in some other embodiments, the first side plate 12 and the second side plate 13 may also have a certain inclination angle. For example, the first side plate 12 and the second side plate 13 may be arranged in an "eight" shape.

[0051] The front end of the pedal 11 has a protruding portion 14 protruding from the first side plate 12 and the second side plate 13, and the front side of the protruding portion 14 is provided with a groove 141. Figure 2 and Figure 5 As shown, the protrusion 14 can be integrally formed with the pedal 11, and the protrusion 14 can be the front end portion of the pedal 11, and the protrusion 14 can protrude from the front ends of the first side plate 12 and the second side plate 13, that is, in the front-to-back direction, the overall length of the pedal 11 can be longer than the first side plate 12 and the second side plate 13, and the rear side of the pedal 11 is flush with the rear ends of the first side plate 12 and the second side plate 13. At this time, the pedal 11 protrudes from the front ends of the first side plate 12 and the second side plate 13 to form the protrusion 14, thereby, a notch structure can be formed below the protrusion 14. Figure 5 As shown, the slot 141 may be a rectangular slot, and the slot 141 may be provided at the front side of the protruding portion 14 and may penetrate the protruding portion 14 in the up-down direction, and the slot opening of the slot 141 may face the front side.

[0052] The front blocking member 2 is arranged at the front side of the vehicle frame 1 and connected between the first side plate 12 and the second side plate 13, and the top side of the front blocking member 2 is fixedly connected to the protrusion 14. Specifically, the front blocking member 2 can also be integrally formed, for example, the front blocking member 2 can also be processed and formed by sheet metal stamping, casting, etc. The front blocking member 2 can be installed at the notch structure below the protrusion 14, wherein the left side of the front blocking member 2 can be welded and fixed to the first side plate 12, the right side of the front blocking member 2 can be welded and fixed to the second side plate 13, and the top side of the front blocking member 2 can be welded and fixed to the protrusion 14.

[0053] The oblique tube 3 is embedded in the groove 141 and fixedly connected to the protrusion 14, and the oblique tube 3 is plugged or fitted with the front blocking member 2 and fixedly connected to the front blocking member 2. Specifically, when installing the oblique tube 3, the oblique tube 3 can be first connected and fixed to the front blocking member 2. For example, the two can be first plugged and assembled through the plug-in structure on the oblique tube 3 and the front blocking member 2, and then the two can be welded and fixed. Then, the whole formed by the oblique tube 3 and the front blocking member 2 can be connected and fixed to the frame 1, wherein the front blocking member 2 can be matched at the notch structure below the protrusion 14, and the rear part of the oblique tube 3 can be embedded in the groove 141 of the protrusion 14, and then any two of the frame 1, the front blocking member 2, and the oblique tube 3 can be connected and fixed by welding.

[0054] It is understandable that, in some other embodiments, the front blocking member 2 may be first welded and fixed to the vehicle frame 1 , and then the inclined tube 3 may be inserted into the slot 141 , and finally all three may be welded and fixed.

[0055] In the frame oblique tube assembly of the embodiment of the present invention, any two of the frame 1, the front blocking member 2, and the oblique tube 3 are connected and fixed, and the frame 1 and the oblique tube 3 are anti-rotationally assembled by embedding the groove 141, which further enhances the limiting constraint effect, improves the compactness, stability and reliability of the assembly, and fully meets the use requirements of the structural strength.

[0056] Secondly, compared with the connection and fixing method by adding reinforcing plates and strengthening plates in the prior art, the frame oblique tube assembly of the embodiment of the present invention does not need to add additional reinforcing plates and strengthening plates, thereby reducing the number of parts and the overall number of welds, thereby reducing the overall cost and simplifying the overall processing technology.

[0057] In some embodiments, the front blocking member 2 includes a connecting plate 21, one of the connecting plate 21 and the oblique tube 3 is provided with a slot, and the other is plugged into the slot. Figure 3 As shown, the slot can be provided at the bottom of the oblique tube 3, and the slot can be a first slot 31, and the first slot 31 can be a rectangular slot, and the first slot 31 can penetrate the oblique tube 3 along the left-right direction. The connecting plate 21 can be provided in the middle position of the front blocking member 2, and the connecting plate 21 can be in the shape of a flat plate. During installation, the connecting plate 21 can be inserted into the first slot 31, and after being plugged in place, the connecting plate 21 and the oblique tube 3 can be welded and fixed. Thus, the plugging and fixing of the oblique tube 3 and the front blocking member 2 is facilitated.

[0058] It should be noted that, in some other embodiments, such as Figure 6 and Figure 7 As shown, the slot can also be provided on the front blocking member 2, specifically, at the top middle position of the connecting plate 21, and the slot can be a second slot 211, and the second slot 211 can also be a rectangular slot and generally penetrate the connecting plate 21 in the front-to-back direction. The width dimension of the bottom of the oblique tube 3 can be slightly smaller than the slot width dimension of the second slot 211. During assembly, the bottom of the oblique tube 3 can be plugged and assembled in the second slot 211, so that the plug-in assembly of the oblique tube 3 and the front blocking member 2 can also be realized. After plugging, the rear side of the oblique tube 3 is still embedded in the slot 141 of the protruding portion 14.

[0059] In some embodiments, the oblique tube 3 is fixedly attached to the front side 212 or the rear side of the connecting plate 21. Figure 8 and Fig. 9 As shown, the front side surface 212 of the connecting plate 21 is the front surface of the connecting plate 21, and the inclined tube 3 can be in contact with the front side surface 212 of the connecting plate 21 and be welded and fixed. Fig.10 and Fig.11As shown, the rear side surface of the connecting plate 21 is the rear surface of the connecting plate 21, the inclined tube 3 can extend into the space enclosed by the connecting plate 21 and fit in contact with the rear side surface of the connecting plate 21, and the inclined tube 3 and the connecting plate 21 are welded and fixed.

[0060] It should be noted that when the oblique tube 3 is in contact with the front side 212 or the rear side of the connecting plate 21 , the rear portion of the oblique tube 3 is still embedded in the groove 141 of the protrusion 14 , thereby limiting the rotation of the oblique tube 3 and enhancing the fixing effect.

[0061] In some embodiments, Figure 1 and Figure 2 As shown, the connecting plate 21 is arranged obliquely downward from the front to the rear, and the oblique tube 3 is also arranged obliquely downward from the front to the rear, and the oblique direction of the connecting plate 21 is consistent with the oblique direction of the oblique tube 3. Therefore, the plug-in assembly of the oblique tube 3 and the connecting plate 21 is facilitated, and the assembly fit is improved.

[0062] In some embodiments, Figure 4 As shown, the width dimension of the connecting plate 21 is also the dimension of the connecting plate 21 in the left-right direction, and the width dimension of the connecting plate 21 gradually increases from top to bottom. Thus, on the one hand, the width dimension of the top of the connecting plate 21 can be adapted to the width dimension of the slot on the oblique tube 3, thereby enhancing the structural stability and compactness of the assembly. On the other hand, this structural design can enhance the overall structural strength of the front blocking member 2, and is also conducive to the decomposition and transmission of the force of the oblique tube 3 downward.

[0063] In some embodiments, the front blocking member 2 includes a third side panel 22 and a fourth side panel 23, the connecting plate 21 is connected between the third side panel 22 and the fourth side panel 23, at least a portion of the third side panel 22 is parallel to and connected to the first side panel 12, and at least a portion of the fourth side panel 23 is parallel to and connected to the second side panel 13.

[0064] like Figure 4 As shown, the third side plate 22 and the fourth side plate 23 can be integrally formed with the connecting plate 21. For example, the connecting plate 21, the third side plate 22, and the fourth side plate 23 can be formed by sheet metal stamping. The third side plate 22 can be located on the left side of the connecting plate 21, and the fourth side plate 23 can be located on the right side of the connecting plate 21.

[0065] The third side panel 22 may be provided with a first folded edge at the rear side, and the first folded edge may be arranged coplanarly with the first side panel 12. The fourth side panel 23 may be provided with a second folded edge at the rear side, and the second folded edge may be arranged coplanarly with the second side panel 13. During installation, the first folded edge may be in contact with the first side panel 12 and welded, and the second folded edge may be in contact with the second side panel 13 and welded. Thus, the fit between the front blocking member 2 and the vehicle frame 1 is improved, and the reliability of the connection is ensured.

[0066] Optionally, the front blocking member 2 may be located between the first side panel 12 and the second side panel 13 , whereby the first side panel 12 and the second side panel 13 may be used to hide the front blocking member 2 , thereby improving the overall appearance.

[0067] In some embodiments, Figure 5 As shown, the protrusion 14 is fan-shaped or arched, and the groove depth direction of the slot 141 is consistent with the extension direction of the symmetry axis of the protrusion 14. The symmetry axis of the protrusion 14 extends along the front-back direction, and the slot 141 is provided at the front end of the protrusion 14, and the slot 141 is located on the symmetry axis of the protrusion 14. Therefore, on the one hand, the plug-in assembly of the inclined tube 3 and the frame 1 is facilitated, and on the other hand, the two sides of the frame 1 can be made symmetrical, thereby ensuring the balance of the structural distribution.

[0068] In some embodiments, the frame 1 includes a first shaping plate 15 and a second shaping plate 16 that are oppositely arranged. The first shaping plate 15 is connected between the first side plate 12 and one side of the pedal 11 , and the second shaping plate 16 is connected between the second side plate 13 and the other side of the pedal 11 .

[0069] For example, Fig.12 As shown, the first styling plate 15 and the second styling plate 16 can be integrally formed on the frame 1. For example, the first styling plate 15 and the second styling plate 16 can also be formed by sheet metal stamping, wherein the first styling plate 15 can be connected to the left side of the pedal 11, the first side plate 12 can be connected to the bottom of the first styling plate 15, the second styling plate 16 can be connected to the right side of the pedal 11, and the second side plate 13 can be connected to the bottom of the second styling plate 16.

[0070] The first and second styling plates 15 and 16 can improve the overall appearance of the frame 1 and facilitate the steering connection between the pedal 11 and the first and second side plates 12 and 13. On the other hand, the first and second styling plates 15 and 16 can also enhance the structural strength.

[0071] Optionally, the pedal 11, the first side plate 12, the second side plate 13, the first shaping plate 15, and the second shaping plate 16 are integrally formed. For example, the entire frame 1 can be formed by sheet metal stamping.

[0072] In some embodiments, the first shaping plate 15 and the second shaping plate 16 each have one or more shaping surfaces 17 located in different planes. Fig.12 As shown, the first shaping plate 15 and the second shaping plate 16 can both be angle steel structures, that is, the cross-sections of the first shaping plate 15 and the second shaping plate 16 can be L-shaped or 7-shaped, and the first shaping plate 15 and the second shaping plate 16 can both be provided with two shaping surfaces 17, and the two shaping surfaces 17 are arranged at an angle. In some other embodiments, the first shaping plate 15 and the second shaping plate 16 can also be provided with three, four, or the like shaping surfaces 17.

[0073] In some embodiments, the frame diagonal tube assembly includes a first styling member 6 and a second styling member 7, the first side panel 12 and the second side panel 13 are both directly connected below the pedal 11, the first styling member 6 is connected to the outer side of the first side panel 12 and adjacent to the connection between the first side panel 12 and the pedal 11, and the second styling member 7 is connected to the outer side of the second side panel 13 and adjacent to the connection between the second side panel 13 and the pedal 11.

[0074] For example, Fig.13 and Fig.14 As shown, the first molding member 6 and the second molding member 7 can both be separate parts, and the cross-sections of the first molding member 6 and the second molding member 7 can both be 7-shaped. The first side plate 12, the second side plate 13, and the pedal 11 can be integrally formed and can form a channel steel structure, the first molding member 6 can be fixed to the outside of the first side plate 12 by welding, and the second molding member 7 can be fixed to the outside of the second side plate 13 by welding.

[0075] Thus, the processing technology of the frame 1 can be simplified, so that the first shaped member 6 and the second shaped member 7 can also be independently designed according to their own needs without being affected or restricted by the structure of the frame 1 itself.

[0076] In some embodiments, the top surface of the first shaping member 6 and / or the top surface of the second shaping member 7 is flush with the top surface of the pedal 11. Fig.13 As shown, the top surface of the first shaped member 6 and the top surface of the second shaped member 7 can both be horizontal planes, and the top surface of the pedal 11 can also be a horizontal plane. After the first shaped member 6 and the second shaped member 7 are assembled, the top surface of the first shaped member 6, the top surface of the second shaped member 7, and the top surface of the pedal 11 can all be located in the same horizontal plane.

[0077] Therefore, on the one hand, the flatness of the overall appearance can be ensured, and on the other hand, the width of the overall tread surface of the frame 1 can be increased, thereby facilitating use by users.

[0078] In some embodiments, a first flange 121 is provided at the bottom of the first side panel 12 , and a second flange 131 is provided at the bottom of the second side panel 13 . Both the first flange 121 and the second flange 131 are folded toward the inside of the frame 1 and are used to install and fix the frame 1 .

[0079] For example, Fig.12 and Fig.14 As shown, the first flange 121 can be integrally formed with the first side plate 12, the second flange 131 can be integrally formed with the second side plate 13, the first flange 121 and the second flange 131 can both extend along the front-rear direction, and the first flange 121 and the second flange 131 can both be provided with a plurality of mounting holes, which are arranged at intervals along the extending direction of the first flange 121 and the second flange 131. During assembly, the mounting holes can be passed through by fasteners, thereby providing mounting points for the bottom cover of the vehicle frame 1, thereby facilitating the mounting and fixing of the bottom cover of the vehicle to the vehicle frame 1.
