Description

Technical Field

[0001] The present application relates to the technical field of treadmills, and in particular to a treadmill lifting mechanism and a treadmill. Background Art

[0002] In the field of modern health and fitness, walking machines, as an important fitness equipment, have been widely used. With people's pursuit of fitness effects and continuous improvement of sports experience, the functions of walking machines are also constantly improving and innovating. Traditional walking machines can only meet general running needs, such as changing the speed of the crawler on the walking machine to imitate the needs of different walking speeds, but cannot meet the changes in terrain and cannot simulate slope terrain.

[0003] Walking machines with slope adjustment are gradually appearing on the market. In the related technology, the walking machine adjusts the height of the table through the slope adjustment structure. The existing slope adjustment structure is arranged on the left and right sides of the rear of the table. The slope adjustment structure on each side includes a front bracket and a rear bracket. The rear end of the front bracket is hinged to the front end of the rear bracket through a hinge shaft. The hinge shaft is provided with a support roller. The front end of the front bracket is hinged to the table, and the rear end of the rear bracket is hinged to the lead screw nut. The lead screw nut is screwed to the lead screw driven by the motor, and the lead screw is fixed to the table with a bearing seat. It can be seen that the slope adjustment structure needs to set up two motors as the driving mechanism, which is relatively costly.

[0029] In the embodiments of this application, please refer to Figure 1-6As shown, the lifting mechanism of a walking machine and the walking machine mainly include: a support frame 1 and a lifting motor 2 installed on the support frame 1; a lifting part, including a support sleeve 3, a sliding member 4, a transmission assembly 5 and a screw rod 6, the sliding member 4 is threadedly connected to the screw rod 6, one end of the screw rod 6 is rotatably connected to the transmission assembly 5, a support sleeve 3 is installed on the transmission assembly 5, the support sleeve 3 is fixedly installed on the support frame 1, and at the same time, a connecting member 7 is installed on the inner wall of the bottom of the support sleeve 3, and the connecting member 7 is slidably matched with the sliding member 4; a transmission rod 8 is driven by the lifting motor 2, the transmission rod 8 is connected to the transmission assembly 5, and the transmission assembly 5 is used to transmit power to the screw rod 6, thereby driving the rotation of the screw rod 6, and the rotation of the screw rod 6 drives the sliding member 4 to move on the screw rod 6, and the height of the lifting part changes.

[0030] Some preferred / improved embodiments based on the above embodiments will be described below. Any one of the following embodiments may be selected, or multiple embodiments may be selected and combined.

[0031] like Figure 4-6 As shown, the transmission assembly 5 includes a housing 501, a first bevel gear 502, a second bevel gear 503 and a sleeve 504. The transmission rod 8 is polygonal, which facilitates the fixing of the reduction gear assembly 10 and the sleeve 504 on the transmission rod 8. The sleeve 504 is sleeved on the transmission rod 8. A bearing is installed on the sleeve 504. The transmission rod 8 is rotatably arranged in the housing 501 through the bearing. The transmission rod 8 and the sleeve 504 can rotate relative to the housing 501. The first bevel gear 502, the second bevel gear 503 and the sleeve 504 are all placed in the housing 501.

[0032] Furthermore, the first bevel gear 502 is installed on the sleeve 504, and the second bevel gear 503 is installed on the screw rod 6. The first bevel gear 502 and the second bevel gear 503 are meshed with each other. The rotation of the transmission rod 8 drives the sleeve 504 and the first bevel gear 502 on the sleeve 504 to rotate, the first bevel gear 502 drives the second bevel gear 503 meshed with it to rotate, and the second bevel gear 503 drives the screw rod 6 fixed thereto to rotate.

[0033] Furthermore, the screw rod 6 and the box body 501 are connected via a bearing, so that the screw rod 6 can rotate relatively to the box body 501 more smoothly.

[0034] like Figure 5As shown, the sliding member 4 includes a slider 401 and a sleeve 402. The slider 401 is threadedly connected to the screw rod 6, and the sleeve 402 is fixed on the slider 401. The sleeve 402 extends out of the support sleeve 3 and does not contact the screw rod 6. When the screw rod 6 rotates, the slider 401 moves under the action of the thread, driving the sliding member 4 to move up and down, thereby changing the height of the lifting part and realizing the lifting function. The sleeve 402 fixed on the slider 401 wraps most of the screw rod 6. The sleeve 402 is used for the connecting member 7 to slide thereon, thereby further limiting the support sleeve 3.

[0035] Furthermore, a gasket 9 is installed at the bottom end of the sliding sleeve 402 for supporting the sliding member 4 .

[0036] like Figure 2-3 As shown, there are two lifting parts, which are symmetrically installed on both sides of the support frame 1 and are respectively connected to the two ends of the transmission rod 8. The transmission rod 8 rotates and starts the two lifting parts to work at the same time.

[0037] Furthermore, a reduction gear assembly 10 is installed on the output end of the lifting motor 2, and the reduction gear assembly 10 is connected to the transmission rod 8, and is used to reduce the rotation speed transmitted to the transmission rod 8 so that the lifting speed of the lifting part is within a suitable range.

[0038] like Figure 6 As shown, the upper portion of the screw rod 6 has a polished rod section, and the polished rod section is used for rotational cooperation with the box body 501 .

[0039] like Figure 1 As shown, the utility model provides a walking machine, comprising the walking machine lifting structure described in any one of the first aspects.

[0040] When in use, the output of the lifting motor 2 reduces the output speed to the transmission rod 8 under the action of the reduction gear assembly 10. The transmission rod 8 is connected to the transmission assembly 5. Under the action of the first bevel gear 502 and the second bevel gear 503, the screw rod 6 is driven to rotate. The rotation of the screw rod 6 drives the sliding member 4 to move up and down, changing the height of the lifting part. The support sleeve 3 is lifted, thereby lifting the support frame 1 and achieving lifting. Similarly, it can also return to its original position.
