DETAILED DESCRIPTION Example

[0023] Please refer to Figure 1 and Figure 2 This embodiment provides a running shoe testing machine base 1 and a running shoe testing machine. The running shoe testing machine includes the base 1, a support frame 2, a lifting rod 3, a foot model 5, and a drive device 4. The base 1 is placed on the ground to support the other components of the running shoe testing machine. The support frame 2 is mounted on the base 1, and the lifting rod 3 is vertically mounted on the support frame 2 and can move up and down. The foot model 5 is disposed at the bottom of the lifting rod 3. The drive device 4 is used to drive the lifting rod 3 upward to a preset position. Under the action of gravity, the lifting rod 3 drops the foot model onto the base 1, thereby simulating the process of a runner's foot landing.

[0024] The base 1 comprises a base 133, a lifting structure 13, and a seat plate 136. The base 133 is a frame structure welded from profiles, with two strip-shaped mounting plates 137 positioned in the center. The lifting structure 13 is fixedly mounted on the mounting plates of the base 133, and the seat plate 136 is horizontally mounted on the lifting structure 13. The lifting structure 13 can move up and down with the seat plate 136, thereby adjusting the landing height of the foot model 5.

[0025] Specifically, the lifting structure 13 utilizes four identical worm-gear lifters 131. Each lifter 131 comprises a housing 1311, a drive shaft 1312, and a lifting shaft 1313. The housing 1311 is bolted to a mounting plate, with the drive shaft positioned horizontally and the lifting shaft positioned vertically. When the drive shaft rotates, it drives the lifting shaft up and down. The four lifters 131 are divided into two groups, each with its drive shaft connected by a connecting shaft. The connecting shafts are each equipped with pulleys, and the two connecting shafts are connected by a timing belt, enabling the drive shafts of the four lifters 131 to rotate synchronously and the lifting shafts of the four lifters 131 to rise and fall synchronously. A crank handle is also provided at the end of the drive shaft, which can be turned to adjust the height of the seat plate. In other embodiments, a drive motor may also be provided, connected to one of the drive shafts. Alternatively, in other embodiments, the lifters 131 may employ other structures.

[0026] A plurality of support seats are provided at the bottom of the seat body, and the support seats include a support plate and a threaded rod. The upper part of the threaded rod passes through the seat body and is fastened by two upper and lower screws; the lower part of the threaded rod is connected to the support plate.

[0027] The support frame 2 includes two vertical rods 21 and a connecting rod 22, and the upper ends of the two vertical rods 21 are fixedly connected by the connecting rod 22. Mounting seats 134 are respectively provided on both sides of the upper part of the base body, and the bottoms of the two vertical rods 21 are respectively connected to the two mounting seats.

[0028] The driving device 4 includes a mounting frame 42 and two telescopic rods 41, wherein the mounting frame 42 is an inverted U-shaped structure, and the bottom of the mounting frame 42 is connected to the upper part of the two vertical rods 21; the upper ends of the two telescopic rods 41 are connected to the upper part of the mounting frame 42, and the lower ends are provided with electromagnets 411.

[0029] The lifting rod 3 is vertically mounted below the drive unit 4. Vertical guide rods 23 are mounted on either side of the lifting rod 3, fixedly connected to the support frame 2. The lifting rod 3 is slidably connected to the guide rods 23 via linear bearings 24. A counterweight support plate is mounted on the lifting rod 3, which is equipped with multiple counterweights 31. Two armatures 32 are also located above the lifting rod 3, positioned below two electromagnets 411. When the telescopic rod 41 extends, the electromagnets 411 move downward to the position of the armatures 32. At this point, the electromagnets 411 are energized, attracting the armatures 32. At this point, when the telescopic rod 41 retracts upward, it pulls the lifting rod 3 and the counterweight upward. Once the lifting rod 3 reaches the preset position, the electromagnets 411 are de-energized, causing the counterweight and the lifting rod 3 to fall freely under the force of gravity, simulating the process of a falling leg.

[0030] Furthermore, the bottom of the support frame 2 is hinged to the base 1, so that the angle of the support frame 2 relative to the base 1 can be adjusted. Specifically, the bottoms of the two vertical rods 21 of the support frame 2 are connected to the base 1 through bearings. In addition, a flip plate 12 is provided at the end of the base 1; the flip plate 12 is a strip plate 71, which extends along the width direction of the base 1 and is rotatably connected to the base 1 through a horizontal axis. A push rod structure 9 is provided on the flip plate 12, one end of the push rod structure 9 is connected to the support frame 2, and the other end is connected to the flip plate 12; the push rod structure 9 can adopt a worm gear lifter.

[0031] In addition, the lower part of the mounting frame 42 of the driving device 4 and the upper part of the vertical rod 21 of the support frame 2 are also hinged through a rotating shaft; an adjusting rod is set at the end of the rotating shaft, and the angle of the mounting frame 42 can be adjusted by rotating the adjusting rod; after adjusting to the preset angle, the adjusting rod is fixed to the support frame 2.

[0032] Furthermore, the lifting rod 3 is fitted with a circular connecting plate, which is equipped with multiple connecting rods 22. These connecting rods 22 surround the lifting rod 3 and are arranged vertically. The connecting rods 22 can move up and down and be fixed in a preset position. The foot model 5 is connected to the lower end of the lifting rod 3 via a ball joint. The upper end of the foot model 5 is equipped with multiple connecting parts, which surround the lifting rod 3. These connecting parts correspond one-to-one with the multiple connecting rods 22 and are connected by tension springs.

[0033] By adjusting the position of the connecting rod 22 , the preload force of the tension spring can be adjusted, thereby simulating the running state of runners with different muscle strengths.

[0034] The entire running shoe testing machine also includes a controller. Multiple sensors are installed on the foot model 5 and the lifting rod 3 to measure the foot model 5's bottom contact angle, maximum rearfoot angle, peak angular velocity, and impact force. The controller is connected to each sensor to collect sensor data.

[0035] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Those skilled in the art will readily appreciate that the present invention is susceptible to various modifications and variations. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
