For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0021] The utility model provides Figures 1-2 In an embodiment of the utility model, a lifting drive device applied to a treadmill comprises: a reduction motor 1 and two sets of lifting devices 3 arranged on both sides of the treadmill platform; a transmission connecting rod 2 is arranged between the reduction motor 1 and the two sets of lifting devices 3, and the reduction motor 1 drives the lifting devices 3 through the transmission connecting rod 2;

[0022] The lifting device 3 includes: a support column 31, a lifting screw 32, a driving gear 36 and a transmission gear 35;

[0023] The lifting screw 32 is vertically arranged upward and arranged in a perpendicular direction to the transmission connecting rod 2; a lifting nut 33 matching with the thread is arranged on the lifting screw 32, the lower end of the support column 31 is installed on the lifting nut 33, and the upper end of the support column 31 is fixedly connected to the treadmill platform;

[0024] The driving gear 36 is installed on the transmission connecting rod 2, and the transmission gear 35 is installed in the lifting screw 32. The driving gear 36 and the transmission gear 35 are vertically meshed to achieve the transmission cooperation between the lifting device 3 and the reduction motor 1;

[0025] When the reduction motor 1 drives the lifting device 3 to perform the lifting and lowering adjustment of the treadmill platform, the reduction motor 1 drives the transmission connecting rod 2 to work, and the effect of driving the lifting screw 32 to rotate is achieved through the cooperation between the driving gear 36 and the transmission gear 35. The rotation of the lifting screw 32 will drive the lifting nut 33 to slide up and down on the lifting screw 32, thereby achieving the effect of lifting and lowering the treadmill platform through the support column 31.

[0026] Preferably, the driving gear 36 and the transmission gear 35 adopt a spiral bevel gear structure, which has higher overall transmission efficiency, more stable transmission ratio, strong load-bearing capacity, and smooth transmission; it can achieve a silent and smooth adjustment effect during the treadmill height adjustment operation.

[0027] Furthermore, in order to improve the transmission stability between the lifting device 3 and the reduction motor 1, the lifting device 3 also includes: a protective shell 34, which encloses and protects the driving gear 36 and the transmission gear 35 to improve the connection stability between the driving gear 36 and the transmission gear 35.

[0028] Furthermore, a support bearing 37 for supporting the transmission connecting rod 2 is also provided in the protective shell 34 . The support bearing 37 is sleeved on the transmission connecting rod 2 to provide a supporting force for the end position of the transmission connecting rod 2 .

[0029] Furthermore, the reduction motor 1 uses a reduction motor 1 model with a built-in travel switch. When the reduction motor 1 drives the lifting device 3 to lift, the built-in travel switch in the reduction motor 1 can control the reduction motor 1 to stop when the lifting device 3 reaches a specified height position, thereby avoiding the lifting device 3 from overtravel.

[0030] Furthermore, the reduction motor 1 uses a reduction motor 1 model with a built-in variable resistor. When the reduction motor 1 drives the lifting device 3 to lift, the speed of the reduction motor 1 can be precisely controlled by the built-in variable resistor in the reduction motor 1, so that the height control of the treadmill platform can be more precise and detailed, which can maximize the overall user experience.

[0031] Furthermore, the reduction motor 1 uses a reduction motor 1 model with a built-in temperature control protection switch. When the reduction motor 1 drives the lifting device 3 to lift, it can play the role of overheat protection of the reduction motor 1, avoid the reduction motor 1 from being damaged due to overheating, and can effectively extend the service life of the overall lifting structure.

[0032] It should also be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, the elements defined by the statement "including a ..." do not exclude the presence of other identical elements in the process, method, article or device including the elements.
