Description

Technical Field

[0001] This invention relates to the field of step technology, and in particular to a support mechanism for a flip-up step. Background Technology

[0002] On driverless pure electric wide-body dump trucks, since electrical circuit maintenance is frequently required, steps are usually installed to facilitate workers' climbing. These steps are generally fixed to the frame, and workers can simply climb them when in use.

[0003] During use, since the existing steps are always exposed, they are prone to scraping against other obstacles while the vehicle is in motion, affecting the vehicle's movement. Although there are some flip-up steps, each time they are folded up or unfolded, it is necessary to reach inside the frame to turn the locking device before the step body can be moved. This is inconvenient to use. Furthermore, after the steps are flipped up, due to the lack of a support mechanism, the steps are prone to rotating automatically, resulting in poor stability during use. Summary of the Invention

[0004] The purpose of this section is to outline some aspects of embodiments of the present invention and to briefly describe some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be construed as limiting the scope of the invention.

[0005] In view of the fact that the flip-up pedals in the above or existing technologies require the user to reach inside the frame to rotate the locking device in order to turn the pedal body, which is inconvenient to use, and that the lack of a support mechanism after the pedal is flipped up results in poor stability, this invention is proposed.

[0011] As a preferred embodiment of the support mechanism for the flip-type step of the present invention, the pushing component includes a horizontal groove disposed on the step body, a first support groove disposed on the horizontal groove, a T-shaped plate disposed on the first support groove, a second spring disposed on the T-shaped plate, and a notch disposed on the T-shaped plate; wherein the horizontal plate of the T-shaped plate is adapted to the horizontal groove.

[0012] As a preferred embodiment of the support mechanism for the flip-type step of the present invention, the sliding component includes a second support groove disposed on the step body, a connecting groove disposed on the second support groove, a connecting block disposed in the connecting groove, a moving block disposed on the connecting block, and a U-shaped rod disposed on the moving block.

[0013] As a preferred embodiment of the support mechanism for the flip-type step of the present invention, the insertion component includes a pin disposed on the step body, a socket disposed on the third cylinder, a second wedge block disposed on the pin, a third spring disposed on the second wedge block, and a third wedge block disposed on the U-shaped rod; wherein the second wedge block and the third wedge block are adapted to each other.

At the same time, during the unfolding process of the step body, the extension frame can be automatically unfolded, and the L-shaped plate can be automatically moved, so that the L-shaped plate, the support frame, and the step body form a triangular structure to support the step body. In addition, when the step body unfolds automatically, the L-shaped plate can also be locked to further ensure the stability of the step body. This solves the problems of flip-up pedals, which require reaching into the frame to rotate the locking device to move the step body, which is inconvenient to use, and the lack of a support mechanism after the step is flipped, resulting in poor stability. This invention achieves the effect of convenient unfolding of the step body and stable use. Attached Figure Description

[0035] Example 1

[0036] Reference Figures 1-4This is the first embodiment of the present invention. This embodiment provides a support mechanism for a flip-type step, which enables quick installation and disassembly of the step body 105. It includes a support component 100, comprising a support frame 101, a fixing block 102 disposed on the support frame 101, a rotating shaft 103 disposed on the fixing block 102, a torsion spring 104 disposed on the rotating shaft 103, and a step body 105 disposed on the rotating shaft 103; and a locking component 200, comprising a locking assembly 201 disposed on the step body 105, and a locking mechanism for... The receiving component 202 is placed on the support frame 101; the mounting component 300 includes an abutting component 301 disposed on the support frame 101, a pushing component 302 disposed on the step body 105, a sliding component 303 disposed on the pushing component 302, an insertion component 304 disposed on the sliding component 303, and a guide component 305 disposed on the support frame 101; the extension component 400 includes a flipping component 401 disposed on the step body 105, and a limiting component 402 disposed on the pushing component 302.

[0037] Specifically, the support frame 101 is fixed above the tires of the unmanned pure electric wide-body dump truck, and the fixing block 102 is fixed on the side wall of the support frame 101. Two fixing blocks 102 are provided. The rotating shaft 103 is rotatably connected to the fixing block 102. The step body 105 is fixedly connected to the rotating shaft 103. The step is equivalent to a small ladder, which makes it convenient for workers to step on the step body 105 to raise the vehicle for maintenance of the upper circuit of the unmanned pure electric wide-body dump truck.

[0038] Furthermore, the engaging assembly 201 includes a first cylinder 201a disposed on the step body 105, a wedge-shaped post 201b disposed on the first cylinder 201a, a receiving opening 201c disposed on the first cylinder 201a and the wedge-shaped post 201b, a mounting groove 201d disposed on the receiving opening 201c, a first wedge block 201e disposed on the mounting groove 201d, a first spring 201f disposed on the first wedge block 201e, a moving rod 201g disposed on the first wedge block 201e, and a disc 201h disposed on the moving rod 201g; the receiving assembly 202 includes a second cylinder 202a disposed on the support frame 101, a limiting block 202b disposed on the second cylinder 202a, a connecting groove 202c disposed on the limiting block 202b, and a lifting ring 202d disposed on the second cylinder 202a.

[0039] The first cylinder 201a is fixedly connected to the step body 105, the wedge-shaped column 201b is fixedly connected to the first cylinder 201a, the receiving opening 201c extends to the upper end of the cylinder, the mounting groove 201d communicates with the receiving opening 201c, the first wedge block 201e is slidably connected to the mounting groove 201d, the first wedge block 201e is elastically connected to the inner wall of the mounting groove 201d through the first spring 201f, the moving rod 201g passes through the wedge-shaped column 201b and is slidably connected to the wedge-shaped column 201b. The first wedge block 201e is fixedly connected to the first cylindrical block 201e, the disc 201h is fixedly connected to the outer end of the moving rod 201g, the second cylinder 202a is fixedly connected to the support frame 101, the upper and lower ends of the second cylinder 202a have different diameters, the upper diameter is smaller than the lower diameter, the limiting block 202b is fixedly connected to the top of the second cylinder 202a, and the lifting ring 202d is slidably connected to the upper end of the second cylinder 202a. Here, both the upper and lower surfaces of the second lifting ring 202d are inclined surfaces 305b, and the limiting block 202b is mushroom-shaped (see details). Figure 4 The connecting groove 202c cooperates with the lifting ring 202d to accommodate the upper end of the lifting ring 202d.

[0040] In use, when the step body 105 is not needed, it is flipped to rotate the shaft 103. The torsion spring 104, or elastic spring, loses its elasticity when the support frame 101 is perpendicular to the step body 105, causing the step body 105 to be close to the support frame 101. At this time, the receiving opening 201c engages with the second cylinder 202a, allowing the limiting block 202b to enter the receiving opening 201c. The diameter of the receiving opening 201c is slightly larger than the diameter of the limiting block 202b to prevent jamming between the receiving opening 201c and the limiting block 202b. After the limiting block 202b enters the receiving opening 201c, the limiting block 202b and the first... When the wedge blocks 201e abut against each other, the first wedge block 201e moves outward, the first spring 201f is compressed, and the moving rod 201g moves outward for guidance. When the limiting block 202b passes the first wedge block 201e, the first spring 201f rebounds, causing the first wedge block 201e to abut against the lower end face of the limiting block 202b. Since the inclined surface 305b of the first wedge block 201e does not abut against the limiting block 202b at this time, the limiting block 202b cannot reset, thus limiting the movement between the step body 105 and the support frame 101. When the step body 105 needs to be used, press the step body 105 again, causing the step body 105 to move downward, thus limiting the movement of the first wedge block 201e. A cylinder 201a moves downwards, and the first wedge block 201e continues to move downwards. At this time, the first wedge block 201e abuts against the lifting ring 202d. Since both the upper and lower ends of the lifting ring 202d are inclined surfaces 305b, the first wedge block 201e will not abut against the lifting ring 202d. Thus, the first wedge block 201e can move to the lower end of the lifting ring 202d, and the upper end face of the first wedge block 201e abuts against the lower end face of the lifting ring 202d. At this time, the step body 105 is released, and under the action of the torsion spring 104, the step body 105 returns to its original position, causing the first cylinder 201a to move upwards. At this time, the first wedge block 201e drives the lifting ring 202d. As the lifting ring 202d moves upward, its upper end abuts against the connecting groove 202c, and the side wall of the limiting block 202b is flush with the side wall of the lifting ring 202d. At this time, since the lifting ring 202d cannot continue to move upward, the first wedge block 201e is squeezed against the side wall of the lifting ring 202d. Since both the upper and lower ends of the lifting ring 202d are inclined surfaces 305b, the first wedge block 201e disengages from the lifting ring 202d and abuts against the side wall of the lifting ring 202d, and continues to move upward. Since the side wall of the limiting block 202b is flush with the side wall of the lifting ring 202d, the first wedge block 201e can continue to move upward along the side wall of the limiting block 202b, thus releasing the limit.

[0041] In summary, by utilizing the movement between the wedge block, the limiting block 202b, and the lifting ring 202d, when storing the step body 105, simply pressing the step body 105 is sufficient, making storage more convenient. Similarly, when using the step body 105, simply pressing the step body 105 again is sufficient, making both storage and use of the step body 105 more convenient.

[0042] Example 2

[0043] Reference Figures 5-12 This is the second embodiment of the present invention. Unlike the previous embodiment, this embodiment provides an abutment component 301 for the support mechanism of the flip-type step, which solves the problem of poor stability after the step body 105 is spread out. The abutment component 301 includes a mounting block 301a disposed on the support frame 101, a drive shaft 301b disposed on the mounting block 301a, an L-shaped block 301c disposed on the drive shaft 301b, a guide groove 301d disposed on the step body 105, an anti-detachment groove 301e disposed on the guide groove 301d, and a third cylinder 301f disposed in the anti-detachment groove 301e. The L-shaped block 301c is rotatably connected to the third cylinder 301f, and the L-shaped block 301c is adapted to the guide groove 301d.

[0044] Specifically, the mounting block 301a is connected to the side wall of the support frame 101, the drive shaft 301b is rotatably connected to the mounting block 301a, the drive shaft 301b is fixedly connected to the L-shaped block 301c, the anti-detachment groove 301e is connected to the guide groove 301d, the left end of the guide groove 301d is arc-shaped, the third cylinder 301f slides in the anti-detachment groove 301e to prevent the L-shaped block 301c from detaching from the guide groove 301d, and the L-shaped block 301c is rotatably connected to the third cylinder 301f.

[0045] Furthermore, the pushing component 302 includes a horizontal groove 302a disposed on the step body 105, a first support groove 302b disposed on the horizontal groove 302a, a T-shaped plate 302c disposed on the first support groove 302b, a second spring 302d disposed on the T-shaped plate 302c, and a notch 302e disposed on the T-shaped plate 302c; wherein the horizontal plate of the T-shaped plate 302c is adapted to the horizontal groove 302a; the sliding component 303 includes a second support groove 303a disposed on the step body 105, a connecting groove 303b disposed on the second support groove 303a, a connecting block 303c disposed in the connecting groove 303b, a moving block 303d disposed on the connecting block 303c, and a U-shaped rod 303e disposed on the moving block 303d;

[0046] The left end of the horizontal groove 302a passes through the step body 105. The first support groove 302b is connected to the horizontal groove 302a. The T-shaped plate 302c is slidably connected to the first support groove 302b. The T-shaped plate 302c is elastically connected to the inner wall of the first support groove 302b through the second spring 302d. The outer end of the T-shaped plate 302c passes through the step body 105 and is provided with a notch 302e. The second support groove 303a is provided at the front end of the step body 105. The connecting groove 303b connects the first support groove 302b and the second support groove 303a. The connecting block 303c slides in the connecting groove 303b. The moving block 303d is fixedly connected to the connecting block 303c and slides in the second support groove 303a. The U-shaped rod 303e is slidably connected to the second support groove 303a.

[0047] Preferably, the insertion component 304 includes a pin 304a disposed on the step body 105, a socket 304b disposed on the third cylinder 301f, a second wedge block 304c disposed on the pin 304a, a third spring 304d disposed on the second wedge block 304c, and a third wedge block 304e disposed on the U-shaped rod 303e; wherein the second wedge block 304c and the third wedge block 304e are adapted to each other; the guide component 305 includes a support block 305a disposed on the support frame 101, an inclined surface 305b disposed on the support block 305a, a flat surface 305c disposed on the support block 305a, and an arcuate surface 305d disposed on the support block 305a.

[0048] It should be noted that the socket 304b extends into the anti-detachment groove 301e, the pin 304a slides within the socket 304b, the second wedge block 304c is fixedly connected to the pin 304a, the second wedge block 304c is elastically connected to the inner wall of the second support groove 303a via the third spring 304d, the third wedge block 304e is fixedly connected to the U-shaped rod 303e, and the bearing block 305a is fixedly connected to the bearing frame 101. Here, the inclined surface 305b, the plane 305c, and the arc surface 305d are continuous. The mounting component 300 also includes a toggle assembly 306, which includes a support port 306a on the step body 105, the support port 306a communicating with the transverse groove 302a, and a toggle bar 306b sliding on the support port 306a. The toggle bar 306b is composed of a first plate and a second plate. The first plate is slidably connected to the support port 306a and fixedly connected to the T-shaped plate 302c. The second plate is perpendicular to the first plate and fixedly connected to multiple second plates.

[0049] In use, when the step body 105 is rotated and unfolded, the step body 105 opens to the left. At this time, the rotating shaft 103 rotates, driving the T-shaped plate 302c to rotate. During the process of the step body 105 rotating to be perpendicular to the support frame 101, the T-shaped plate 302c first abuts against the support block 305a, causing the T-shaped plate 302c to move. The second spring 302d is compressed, causing the connecting block 303c to slide in the connecting groove 202c, causing the moving block 303d to move outward, thereby moving the U-shaped rod 303e, causing the first wedge block 201e to push the second wedge block 304c, causing the pin 304a to move upward, thereby causing the pin 304a to move upward. 04a does not extend into the anti-detachment groove 301e. When the step body 105 is flipped, the L-shaped plate cooperates with the guide groove 301d to guide the step body 105. The third cylinder 301f is rotatably connected to the L-shaped plate to prevent the L-shaped plate from jamming. When the step body 105 is continued to be moved, the L-shaped plate slides in the guide groove 301d, and the T-shaped plate 302c moves from the inclined surface 305b of the bearing block 305a to the plane 305c. As the step body 105 moves, the end of the T-shaped plate 302c abuts against the arc surface 305d of the bearing block 305a, so that the T-shaped plate 302c always remains in a compressed state. As the L-shaped plate is about to detach from the support block 305a, it moves to a position close to one end of the guide groove 301d, and the insertion port 304b on the third cylinder 301f is about to align with the pin 304a. At this time, the step body 105 is close to 180°. However, when the step body 105 is unfolded, it can be less than 180° to allow the T-shaped plate 302c to engage with the support block. At this time, the multiple L-shaped plates, the support frame 101, and the step body 105 form a triangular structure to support the step body 105 and maintain its stability when stepped on. Then, the step body 105 is moved to disengage the T-shaped plate 302c from the support block 305a. At this time, the second spring 302d extends, and the connecting block 303c slides in the connecting groove 202c, causing the moving block 303d to move inward, thereby moving the U-shaped rod 303e, causing the first wedge block 201e to push the second wedge block 304c, causing the pin 304a to move downward, thereby inserting the pin 304a into the socket 304b, preventing the L-shaped plate from sliding between the guide groove 301d, and ensuring the stability of the step body 105 when unfolded. When disassembly is required, simply move the lever 306b so that the outer end of the T-shaped plate 302c can move onto the arc surface 305d of the bearing block 305a, thereby facilitating the reset of the step body 105.

[0050] In summary, when the step body 105 is unfolded, the L-shaped plate can move automatically and support the step body 105. When the T-shaped plate 302c is detached from the bearing block 305a, the L-shaped plate can be automatically locked to prevent the L-shaped plate from loosening, resulting in a better support effect and ensuring the stability of the step body 105 during use.

[0051] Example 3

[0052] Reference Figure 13 This is the third embodiment of the present invention. Unlike the previous embodiment, this embodiment provides a flipping component 401, which solves the problem of how to automatically open the extension frame 401c when the step body 105 is opened. It includes an inner groove 401a disposed on the step body 105, a support shaft 401b disposed on the inner groove 401a, and an extension frame 401c disposed on the support shaft 401b. The limiting component 402 includes a limiting rod 402a disposed on the T-shaped plate 302c, and a limiting opening 402b disposed on the extension frame 401c.

[0053] Specifically, the support shaft 401b is rotatably connected to the inner wall of the inner groove 401a, the extension frame 401c is fixedly connected to the support shaft 401b, the limiting rod 402a is fixedly connected to the T-shaped plate 302c, the limiting rod 402a passes through the first support groove 302b and is slidably connected to the step body 105, and the limiting port 402b is set on the extension frame 401c and is directly opposite to the limiting rod 402a.

[0054] When in use, when the T-shaped plate 302c abuts against the inclined surface 305b of the bearing block 305a, the T-shaped plate 302c moves, and the second spring 302d is compressed. When the T-shaped plate 302c moves, it can drive the limiting rod 402a to move inward and disengage from the limiting port 402b. At this time, the extension frame 401c lacks a limit. Under the action of gravity, the extension frame 401c automatically opens. After the extension frame 401c opens, it abuts against the inside of the inner groove 401a to ensure stability when a person steps on it.

[0055] In summary, when the step body 105 rotates, it can also contact the limit of the extension frame 401c, causing the extension frame 401c to open automatically without the need for subsequent opening, making it more convenient to use. In addition, the extension frame 401c is supported by the inner groove 401a, ensuring stability when stepping.
