Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Example 1

[0022] Please see Figures 1-5 The present invention provides the following technical solution: a novel bone fracture assistive vehicle, including an assistive vehicle main frame 6, a rear wheel frame 7 provided on one side of the assistive vehicle main frame 6, a seat cushion 8 fixed on the upper end of the assistive vehicle main frame 6, a support frame 3 provided on the upper end of the side of the assistive vehicle main frame 6 away from the rear wheel frame 7, a pedal adjustment component 4 installed on one end surface of the assistive vehicle main frame 6, a front wheel frame 5 provided on the bottom end of the side of the assistive vehicle main frame 6 away from the rear wheel frame 7, a handlebar 1 provided on the upper end of the support frame 3, and a brake self-locking component 2 provided on one side of the handlebar 1.

[0023] Specifically, the pedal adjustment assembly 4 includes a pedal body 41, a mounting sleeve 42, a limiting device 43, a mounting rod 44, a positioning seat 45, a positioning nut 46, a mounting hole 47, and a fastening bolt 48. The main frame 6 of the electric bicycle has a mounting hole 47 inside one end, and a fastening bolt 48 is installed inside the mounting hole 47. One end of the fastening bolt 48 is connected to the positioning nut 46. The surface of the fastening bolt 48 is provided with a positioning seat 45. The mounting rod 44 is fixed to one side of the positioning seat 45. The mounting sleeve 42 is sleeved on the surface of the mounting rod 44. The pedal body 41 is provided on one side of the mounting sleeve 42. The surface of the mounting rod 44 is provided with a limiting device 43 corresponding to the mounting sleeve 42.

[0024] By adopting the above technical solution, when a fracture patient is moving while sitting on an assistive vehicle, a footrest body 41 can be installed according to the patient's needs to support and place their legs. First, the positioning seat 45 is placed against one side surface of the assistive vehicle's main frame 6. Then, the fastening bolt 48 is passed through the positioning seat 45 and the mounting hole 47, and the positioning nut 46 is tightened to fix the fastening bolt 48, ensuring the convenience and stability of the positioning seat 45 installation and improving the strength of the mounting rod 44.

[0025] Specifically, both the mounting rod 44 and the mounting sleeve 42 are hexagonal, the positioning seat 45 adopts a U-shaped frame, and the mounting rod 44 and the positioning seat 45 are fixed by brazing.

[0026] By adopting the above technical solution, the stability of the installation of the mounting sleeve 42 and the mounting rod 44 is ensured, and the installation strength is improved.

[0027] Specifically, the limiting device 43 includes a limiting spring 431, a telescopic rod 432, a top cover 433, a positioning post 434, a positioning hole 435, and a clamping plate 436. The upper end of the mounting rod 44 is provided with a top cover 433, and the telescopic rod 432 is symmetrically arranged inside the top cover 433. One end of the telescopic rod 432 is fixed with a clamping plate 436, and the surface of the telescopic rod 432 is provided with a limiting spring 431. The bottom end of the top cover 433 is fixed with a positioning post 434, and the interior of the mounting rod 44 is provided with a positioning hole 435 corresponding to the positioning post 434.

[0028] By adopting the above technical solution, the pedal body 41 is installed according to the position of the leg that the fracture patient needs to support. The mounting sleeve 42 is fitted onto the surface of the mounting rod 44. Then, the two sets of clamping plates 436 are pulled outward at the same time, which causes the limiting spring 431 to stretch. At the same time, the telescopic rod 432 is stretched under force, which aligns the positioning post 434 with the positioning hole 435 and moves the upper cover 433 down. When the positioning post 434 is inserted into the interior of the positioning hole 435, the clamping plate 436 is released. At this time, the limiting spring 431 returns to its original position, which causes the clamping plate 436 to clamp the surface of the mounting rod 44, ensuring the convenience and stability of the installation of the upper cover 433. At the same time, it can limit and block the mounting sleeve 42 to prevent it from falling off, thus ensuring the quality of use of the pedal body 41.

[0029] In this embodiment, when a fracture patient is moving while sitting on the assisted vehicle, the pedal body 41 can be installed according to the patient's needs to support and place their legs. First, the positioning seat 45 is placed against one side surface of the assisted vehicle main frame 6. Then, the fastening bolt 48 is passed through the positioning seat 45 and the mounting hole 47. Finally, the positioning nut 46 is tightened to fix the fastening bolt 48, ensuring the convenience and stability of the positioning seat 45 installation and improving the strength of the mounting rod 44.

[0030] Next, install the pedal body 41 according to the position of the leg that the fracture patient needs to support. Fit the mounting sleeve 42 onto the surface of the mounting rod 44. Then, pull the two sets of clamping plates 436 outward at the same time to stretch the limiting spring 431. At the same time, the telescopic rod 432 is stretched under force, aligning the positioning post 434 with the positioning hole 435 and moving the upper cover 433 down. When the positioning post 434 is inserted into the interior of the positioning hole 435, release the clamping plate 436. At this time, the limiting spring 431 resets and causes the clamping plate 436 to clamp the surface of the mounting rod 44, ensuring the convenience and stability of the installation of the upper cover 433. At the same time, it can limit and block the mounting sleeve 42 to prevent it from falling off, ensuring the quality of use of the pedal body 41.

[0031] Example 2

[0032] The difference between this embodiment and embodiment 1 is that, specifically, the brake self-locking assembly 2 includes a brake mounting base 21, a mounting shaft 22, a fixed torsion spring 23, a brake lever 24, a lever 25, an abutment block 26, a limit stop 27, and a connecting block 28. The brake mounting base 21 is provided on one side of the stem 1. The brake lever 24 is provided inside the brake mounting base 21. The mounting shaft 22 is mounted on one side of the brake lever 24. The fixed torsion spring 23 is provided on the surface of the mounting shaft 22. The lever 25 is provided on one side of the mounting shaft 22. The connecting block 28 is provided inside the lever 25. The abutment block 26 is fixed on one side of the connecting block 28. The limit stop 27 is provided inside the brake mounting base 21 corresponding to the abutment block 26.

[0033] By adopting the above technical solution, when braking the electric bicycle, the user presses the brake lever 24 to make it rotate. At the same time, the mounting shaft 22 inside the mounting base moves with the brake lever 24. At this time, the fixed torsion spring 23 abutting against the surface of the connecting block 28 performs a reset operation, and the abutting block 26 is misaligned with the limit block 27. At this time, the fixed torsion spring 23 will push the connecting block 28 and the toggle block 25 on its surface to rotate along the mounting shaft 22. When the toggle block 25 rotates along the mounting shaft 22, it will drive the abutting block 26 to swing, thereby locking the abutting block 26 on one side of the limit block 27 to complete the self-locking of the brake lever 24, so that the brake lever 24 no longer automatically resets, improving the stability of the equipment and preventing slippage.

[0034] When the equipment needs to be reused, press the brake lever 24 while rotating the lever 25 along the mounting shaft 22. The rotation of the lever 25 causes the connecting block 28 to abut against one side of the fixed torsion spring 23, thus tightening it. At the same time, the abutting block 26 on one side of the connecting block 28 can be pulled out from one side of the limit block 27. While keeping the lever 25 pressed, release the brake lever 24 to reset the brake lever 24, so that the equipment can continue to move and improve the use of the equipment.

[0035] Specifically, the surface of the brake lever 24 is provided with a mounting base corresponding to the mounting shaft 22, and the bottom end of the mounting base is provided with a slot corresponding to the bottom of the fixed torsion spring 23.

[0036] By adopting the above technical solution, the mounting shaft 22 is installed stably, ensuring that it can move simultaneously with the brake lever 24.

[0037] In this embodiment, when braking the electric bicycle, the user presses the brake lever 24 to rotate it. At the same time, the mounting shaft 22 inside the mounting base moves with the brake lever 24. At this time, the fixed torsion spring 23 abutting against the surface of the connecting block 28 performs a reset operation, and the abutting block 26 is misaligned with the limit block 27. At this time, the fixed torsion spring 23 pushes the connecting block 28 and the toggle block 25 on its surface to rotate along the mounting shaft 22. When the toggle block 25 rotates along the mounting shaft 22, it will drive the abutting block 26 to swing, thereby locking the abutting block 26 on one side of the limit block 27 to complete the self-locking of the brake lever 24, so that the brake lever 24 no longer automatically resets, improving the stability of the equipment and preventing slippage.

[0038] When the equipment needs to be reused, press the brake lever 24 while rotating the lever 25 along the mounting shaft 22. The rotation of the lever 25 causes the connecting block 28 to abut against one side of the fixed torsion spring 23, thus tightening it. At the same time, the abutting block 26 on one side of the connecting block 28 can be pulled out from one side of the limit block 27. While keeping the lever 25 pressed, release the brake lever 24 to reset the brake lever 24, so that the equipment can continue to move and improve the use of the equipment.

[0039] The working principle and usage process of this utility model: When this utility model is in use, when a fracture patient is moving on the assistive vehicle, the pedal body 41 can be installed according to the needs of the fracture patient to support and place their legs. First, the positioning seat 45 is placed against one side surface of the assistive vehicle main frame 6. Then, the fastening bolt 48 is passed through the positioning seat 45 and the mounting hole 47. Then, the positioning nut 46 is tightened to fix the fastening bolt 48, ensuring the convenience and stability of the installation of the positioning seat 45 and improving the strength of the mounting rod 44.

[0040] Next, install the pedal body 41 according to the position of the leg that the fracture patient needs to support. Fit the mounting sleeve 42 onto the surface of the mounting rod 44. Then, pull the two sets of clamping plates 436 outward at the same time to stretch the limiting spring 431. At the same time, the telescopic rod 432 is stretched under force, aligning the positioning post 434 with the positioning hole 435 and moving the upper cover 433 down. When the positioning post 434 is inserted into the interior of the positioning hole 435, release the clamping plate 436. At this time, the limiting spring 431 resets and causes the clamping plate 436 to clamp the surface of the mounting rod 44, ensuring the convenience and stability of the installation of the upper cover 433. At the same time, it can limit and block the mounting sleeve 42 to prevent it from falling off, ensuring the quality of use of the pedal body 41.

[0041] When braking the electric bicycle, the user presses the brake lever 24 to rotate it. At the same time, the mounting shaft 22 inside the mounting base moves with the brake lever 24. At this time, the fixed torsion spring 23 abutting against the surface of the connecting block 28 performs a reset operation, and the abutting block 26 is misaligned with the limit block 27. At this time, the fixed torsion spring 23 pushes the connecting block 28 and the toggle block 25 on its surface to rotate along the mounting shaft 22. When the toggle block 25 rotates along the mounting shaft 22, it will drive the abutting block 26 to swing, thereby locking the abutting block 26 on one side of the limit block 27 to complete the self-locking of the brake lever 24, so that the brake lever 24 no longer automatically resets, improving the stability of the equipment and preventing slippage.

[0042] When the equipment needs to be reused, press the brake lever 24 while rotating the lever 25 along the mounting shaft 22. The rotation of the lever 25 causes the connecting block 28 to abut against one side of the fixed torsion spring 23, thus tightening it. At the same time, the abutting block 26 on one side of the connecting block 28 can be pulled out from one side of the limit block 27. While keeping the lever 25 pressed, release the brake lever 24 to reset the brake lever 24, so that the equipment can continue to move and improve the use of the equipment.
