Detailed Implementation

[0028] The following description is intended to disclose the present invention so that those skilled in the art can implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art.

[0029] like Figure 1-10 As shown in the figure, this application discloses a single-pulley running board motor mounting structure with a large-size mounting cavity, which is installed on the side of the walking machine near the front roller 200 to provide driving force to the front roller 200. The walking machine includes a support frame 100, which is a rectangular frame including two parallel support tubes 110. Multiple support bars 120 are arranged along the length of the support tubes 110. The two ends of the support bars 120 are fixedly connected to the support tubes 110 on the corresponding sides to improve the support strength of the support frame. A connecting part 1100 is provided on the upper surface of the support tubes 110.

[0030] A front roller 200 is installed at the front end of the support frame 100, and a motor 600 connected to and providing driving force is provided on one side of the front roller 200. A rear roller 300 parallel to the front roller 200 is installed at the rear end of the support frame 100. The running belt 400 is connected to the front roller 200 and the rear roller 300. The rotation of the front roller 200 and the rear roller 300 drives the running belt 400 to drive in one direction. The running belt 400 is a long, hollow ring, and the running plate 500 is set inside the hollow ring. The running belt 400 wraps around the support frame 100, forming a motion contact plane on the upper side of the support frame 100. The output shaft of the motor 600 is connected to the front roller 200, driving the front roller 200 to rotate. The front roller 200 drives the running belt 400 to move upward on the motion contact plane.

[0031] In this embodiment, the lengths of the support tubes 110 on both sides are inconsistent. There is a gap between the front end face of one side's support tube 110 and the front roller 200, serving as a space to accommodate the motor mounting housing 700. The motor mounting housing 700 is installed within this gap and welded to the support tube 110 on that side. This not only makes the overall structure more compact and reduces the overall volume, but also shortens the motion transmission distance and improves transmission efficiency.

[0032] Specifically, the motor mounting housing 700 has an elongated mounting cavity 710 with an open top for housing the motor 600. The motor 600 is fixedly mounted within this cavity. The volume of the cavity 710 is larger than the volume of the motor 600, facilitating the complete accommodating of the motor 600. The output shaft of the motor 600 is located on the side away from the running plate 400 and penetrates the first sidewall 720 of the motor mounting housing 700 on the corresponding side. A pulley 800 is coaxially connected to the front roller 200 and is also located within the mounting cavity 710. The pulley 800 is connected to the output shaft of the motor 600 via a belt 810. One end of the front roller 200 penetrates the first sidewall 720 of the motor mounting housing. The motor 600 is miniaturized and can be flexibly installed within the mounting cavity 710 of the motor mounting housing without requiring additional space for the motor, effectively saving space.

[0033] In this embodiment, the bottom 730 of the motor mounting housing 700 is provided with a first slot 731 corresponding to the position of the pulley 800 and a second slot 732 corresponding to the position of the motor 600, which facilitates heat dissipation during operation, avoids heat accumulation affecting performance, and improves service life.

[0034] The motor mounting housing 700 also has a second side wall 740 opposite to the first side wall 720. The second side wall 740 has an upward-opening arc-shaped groove that extends through the upper surface of the second side wall 740, so that the front roller 200 can pass through one side wall.

[0035] In this embodiment, the running plate 500 has an opening 510 on the end face of the side near the motor mounting housing 700, which is close to the motor 600, to provide space for the installation of the motor mounting housing 700. The opening 510 is located on the end face, which makes it easier to control the size of the opening 510, reducing the occurrence of excessively large cutting sizes and thus reducing waste of sheet material.

[0036] The top of the second sidewall 740 of the motor mounting housing has a horizontal bend 741, which fits against the bottom surface of the running plate 500 and is fixed to the running plate 500 with screws. Because the motor mounting housing 700 is relatively wide, its stability is affected by only being fixedly connected to the end face of the shorter support tube 110, especially during the operation of the motor 600, which can easily cause vibration. Therefore, adding a connection point improves the installation stability of the motor mounting housing 700.

[0037] In this embodiment, the support tube 110 is a square hollow tube, which ensures strength while reducing its own weight, thereby reducing the weight of the whole machine.

[0038] In this embodiment of the application, a protective cover 1000 is connected to the rear end of the support tube 110.

[0039] In this embodiment, each support tube 110 has at least one pad 900 on its underside for anti-slip and sound insulation. Preferably, the pad 900 is positioned slightly rearward of the support tube 110. The pad 900 has a slight elasticity and can be made of rubber, silicone, or PVC to better provide shock absorption and cushioning performance. To further improve the anti-friction properties of the pad 900, micro-protruding particles are formed on the bottom of the pad 900 to enhance its friction with the ground.

[0040] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
