Description

Technical Field

[0001] This utility model relates to the field of treadmill technology, specifically to a shock-absorbing and noise-reducing adaptive lifting motor for treadmills. Background Technology

[0002] Modern fitness equipment such as treadmills typically use AC motors for their lifting drive mechanisms. These motors are reduced in speed by a gearbox, converting the high-speed, low-torque AC motor into the required low-speed, high-torque power output. A lead screw then converts this power output into a linear output. However, existing lifting motors tend to generate significant internal noise during operation, affecting the frequency of use of the equipment. Furthermore, the vigorous vibrations generated during treadmill use can also disrupt the motor's operation. Therefore, a shock-absorbing and noise-reducing adaptive lifting motor for treadmills has been designed.

[0003] A hoisting motor, authorized by announcement number CN208820611U, includes a motor body, a gearbox assembly, and a lead screw. The lower end of the motor body is mounted on the gearbox assembly, and the lead screw passes through the gearbox assembly. The gearbox assembly includes an upper gearbox shell and a lower gearbox shell that are matched vertically. Inside the gearbox assembly, there are upper O-rings, upper flat bearings, lead screw gears, lower flat bearings, and lower O-rings that contact each other sequentially from top to bottom. The upper surface of the upper O-ring contacts the inner surface of the upper gearbox shell, and the lower surface of the lower O-ring contacts the inner surface of the lower gearbox shell. The motor body drives the gearbox assembly to drive the lead screw to rise or fall. The advantage of this utility model is that because it has upper and lower O-rings that contact the inner surfaces of the upper and lower gearbox shells respectively, the upper and lower flat bearings inside the gearbox assembly will not wobble axially when the lead screw reciprocates up and down, reducing the vibration and noise of the hoisting motor and making the reciprocating motion of the lead screw smoother.

[0004] Based on existing solutions and actual production and processing, current adaptive lifting motors for treadmills still have some problems: First, lifting motors generate a lot of noise when used on treadmills, thus affecting the frequency of treadmill use. Second, lifting motors have many internal parts, which are prone to damage, thus requiring disassembly and repair. Finally, when used on a treadmill, the lifting motor is prone to vibration with the movement of people, which can damage the motor. Therefore, this utility model provides a shock-absorbing and noise-reducing adaptive lifting motor for treadmills to solve the above-mentioned problems. Utility Model Content

[0005] The purpose of this utility model is to provide a shock-absorbing and noise-reducing adaptive lifting motor for treadmills, in order to solve the problems mentioned in the background art, such as the excessive noise generated by lifting motors when used on treadmills, which affects the frequency of use of treadmills; secondly, the large number of internal parts of lifting motors, which are prone to damage and therefore require disassembly and repair; and finally, the vibration of lifting motors on treadmills with the movement of people, which can cause motor damage.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a shock-absorbing and noise-reducing adaptive lifting motor for a treadmill, comprising: a first protective shell for installation, and a second protective shell stably installed on the upper end of the first protective shell;

[0007] It also includes: the left and right ends of the second protective shell are provided with disassembly mechanisms, wherein the disassembly mechanism includes a first fixing bolt, a connecting rod, a first nut and a first spring, the outside of the first fixing bolt is connected to the connecting rod and the first nut, and the first nut is located at the left end of the connecting rod, and the lower right end of the connecting rod is provided with a first spring;

[0008] The second fixing bolt has a shock-absorbing mechanism at its rear end, which includes a second nut, a support frame, and a second spring. The second fixing bolt has a second nut and a support frame on its outer side, with the support frame located at the rear end of the second nut and a second spring in the middle of the support frame.

[0009] Preferably, a motor body is provided on the upper left side of the second protective shell, and a first gear is installed on the lower end of the motor body. The right end of the first gear is connected to the second gear in a meshing manner, and a third gear is provided on the lower end of the second gear.

[0010] Preferably, the right side of the third gear is connected to the fourth gear in an meshing manner, the right end of the fourth gear is connected to the fifth gear in an meshing manner, and the interior of the fifth gear is connected to the threaded rod in a threaded manner.

[0011] Preferably, the inner walls of both the first protective shell and the second protective shell are provided with diaphragm pads, and the first fixing bolt is fixedly installed at the left and right ends of the second protective shell, and the outer side of the first fixing bolt is connected to the first nut by means of threads.

[0012] Preferably, the lower end of the first fixing bolt forms a sliding structure inside the left and right ends of the first protective shell, and the outer side of the lower end of the first fixing bolt is in contact with the first spring.

[0013] Preferably, the outer side of the second fixing bolt is connected to the second nut by a thread, and the support frame forms a sliding structure on the outer side of the second nut.

[0014] Compared with the prior art, the beneficial effects of this utility model are: the shock-absorbing and noise-reducing adaptive lifting motor of the treadmill facilitates noise reduction inside the lifting motor, extends the usage frequency of the treadmill, facilitates disassembly and maintenance of the lifting motor, and facilitates shock absorption treatment of the lifting motor in use.

[0015] 1. The device is equipped with a first protective shell, a second protective shell, and a diaphragm. When noise reduction is required inside the lifting motor, the motor body drives the second gear to rotate via the first gear. The second gear then drives the third gear to rotate synchronously. The third gear meshes with the fourth gear, and the fourth gear meshes with the fifth gear. Therefore, the third gear drives the fifth gear to rotate via the fourth gear. The fifth gear is threadedly connected to a threaded rod, thus the fifth gear drives the threaded rod to move up and down. The noise generated by the meshing is reduced by the diaphragm inside the first and second protective shells, which helps to reduce noise inside the lifting motor and extend the usage frequency of the treadmill.

[0016] 2. The device is equipped with a first fixing bolt, a connecting rod, and a first spring. When it is necessary to disassemble and repair the inside of the hoisting motor, the first nut connected to the outside of the first fixing bolt is loosened and removed. Then, the connecting rod is pinched and slid to the left and right sides, so that the lower end of the connecting rod compresses the first spring and retracts. The upper end of the connecting rod is then removed from the outside of the first fixing bolt. At this time, the second protective shell can be removed from the upper end of the first protective shell, which facilitates the disassembly and repair of the hoisting motor.

[0017] 3. It is equipped with a second fixing bolt, a support frame, and a second spring. When vibration damping is required when using the lifting motor, first rotate the second nut and move it along the path of the second fixing bolt. This causes the second nut to drive the support frame to compress the second spring along the path of the second fixing bolt, thereby adjusting the vibration damping device. This allows the lifting motor installed on the treadmill to reduce vibration and facilitates vibration damping treatment of the lifting motor in use. Attached Figure Description

Detailed Implementation

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. 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.

[0025] Please see Figures 1-5 This utility model provides a technical solution: a shock-absorbing and noise-reducing adaptive lifting motor for treadmills, comprising a first protective shell 1, a second protective shell 2, a motor body 3, a first gear 4, a second gear 5, a third gear 6, a fourth gear 7, a fifth gear 8, a threaded rod 9, a diaphragm pad 10, a first fixing bolt 11, a connecting rod 12, a first nut 13, a first spring 14, a second fixing bolt 15, a second nut 16, a support frame 17, a second spring 18, and a connecting bolt 19.

[0026] When using a shock-absorbing and noise-reducing treadmill with an adaptive lifting motor, such as the one with... Figure 1 Appendix Figure 2 Appendix Figure 3 and attached Figure 5As shown, the inner walls of the first protective shell 1 and the second protective shell 2 are both provided with diaphragm pads 10. The outer side of the second fixing bolt 15 is connected to the second nut 16 by a thread. The support frame 17 forms a sliding structure on the outer side of the second nut 16. Since the inner walls of the first protective shell 1 and the second protective shell 2 are provided with diaphragm pads 10, the diaphragm pads 10 block the noise generated by the internal parts of the first protective shell 1 when they are in operation, so that the internal noise of the lifting motor is reduced, and the user's experience of using the treadmill is improved. Since the lifting motor is mainly limited to the position where the support frame 17 needs to be used by the connecting bolt 19, the treadmill will vibrate when it is in use. In order to avoid affecting the use of the lifting motor, the second nut 16 is rotated to move along the path of the second fixing bolt 15, so that the second nut 16 drives the support frame 17 to squeeze the second spring 18 along the path of the second fixing bolt 15, adjusting the internal elasticity of the second spring 18, thereby reducing the vibration frequency of the lifting motor. This is the adaptive lifting motor usage mode of the shock-absorbing and noise-reducing treadmill.

[0027] When disassembling and repairing the hoist motor, for example, attaching... Figure 1 Appendix Figure 3 and attached Figure 4As shown, a motor body 3 is located on the upper left side of the second protective shell 2. A first gear 4 is installed on the lower end of the motor body 3. The right end of the first gear 4 is connected to the second gear 5 in a meshing manner. A third gear 6 is located on the lower end of the second gear 5. The right side of the third gear 6 is connected to the fourth gear 7 in a meshing manner. The right end of the fourth gear 7 is connected to the fifth gear 8 in a meshing manner. The interior of the fifth gear 8 is connected to the threaded rod 9 in a threaded manner. A first fixing bolt 11 is fixedly installed on both the left and right ends of the second protective shell 2. The outer side of the first fixing bolt 11 is connected to the first nut 13 in a threaded manner. The lower end of the first fixing bolt 11 forms a sliding structure inside both the left and right ends of the first protective shell 1. The outer side of the lower end of the first fixing bolt 11 is in a contact state with the first spring 14. When the motor body 3 drives the second gear 5 through the first gear 4... The second gear 5 rotates, and the third gear 6 rotates synchronously. The third gear 6 meshes with the fourth gear 7, and the fourth gear 7 meshes with the fifth gear 8. Therefore, the third gear 6 drives the fifth gear 8 to rotate through the fourth gear 7. The interior of the fifth gear 8 is threadedly connected to the threaded rod 9. Thus, the fifth gear 8 drives the threaded rod 9 to move up and down. The internal parts are prone to damage due to prolonged movement. Therefore, the first nut 13 connected to the outside of the first fixing bolt 11 is loosened and removed. Then, the connecting rod 12 is pinched and slid to the left and right sides, so that the lower end of the connecting rod 12 compresses the first spring 14 and the upper end of the connecting rod 12 is detached from the outside of the first fixing bolt 11. The second protective shell 2 can then be removed from the upper end of the first protective shell 1 to check the damage to the internal parts and carry out repairs. This is the disassembly and repair method of the Yangsheng motor.
