Description

Technical Field

[0001] This utility model relates to the field of lifting motor technology, specifically a lifting motor for a treadmill with track cushioning. Background Technology

[0002] A lift motor is a type of motor used to drive the lifting and lowering of fitness equipment, primarily for functions such as incline adjustment on treadmills. The lift motor achieves the lifting and lowering action of the fitness equipment through the coordinated operation of the motor body, gearbox assembly, and lead screw.

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 there are upper and lower O-rings, which 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 lifting motor, and making the reciprocating motion of the lead screw smoother.

[0004] However, existing lifting motors are not easy to receive electrical signals from the track vibration sensor during use, making it difficult for the device to adjust the output torque in real time according to the sensor information. This causes the lift generated by the device to resonate with the force generated when the user lands, affecting the performance of the treadmill.

[0005] Therefore, in order to address the above problems, it is urgent to carry out innovative design based on the existing lifting motor. Utility Model Content

[0006] The purpose of this invention is to provide a lifting motor for a treadmill with a track cushioning system, in order to solve the problem mentioned in the background art that it is inconvenient to receive the electrical signals transmitted by the track vibration sensor during use, making it difficult for the device to adjust the output torque of the device in real time according to the sensor information, and causing the lift generated by the device to resonate with the force generated by the user's landing, thus affecting the performance of the treadmill.

[0010] The second support plate is installed in the middle of the lead screw, and a plane bearing is provided on the outer side of the second support plate. An O-ring is attached to the outer side of the plane bearing. An outer cylinder is provided on the upper side of the lead screw, and a third limiting rod passes through the outer side of the outer cylinder.

[0011] In one possible implementation, the motor controller and the positioning block are engaged relative to each other, and the positioning block is symmetrically arranged about the central axis of the motor controller.

[0012] In one possible implementation, both the planar bearing and the O-ring are arranged symmetrically about the central axis of the second support disk.

[0013] In one possible implementation, the linkage heat dissipation assembly includes a support frame mounted on the upper side of the motor shaft body, and a second limiting rod passes through the outer side of the support frame. A support block is provided on the inner side of the support frame, and an air intake fan blade is provided on the outer side of the support block.

[0014] The second limiting rod is threadedly connected to both the support frame and the motor body, and the second limiting rod is symmetrically arranged about the central axis of the support frame.

[0017] The locking block is engaged with the first support plate, and the locking block is threadedly connected to the drive rod.

[0018] In one possible implementation, the guide rod is slidably connected to the reducer body, and the longitudinal section of the guide rod has a "T" shaped structure.

[0019] In one possible implementation, the second drive disc is engaged with the first drive disc, and the first drive disc and drive rod are rotatably connected relative to the reducer body.

[0020] Compared with the prior art, the beneficial effects of this utility model are as follows: The lifting motor of this belt-cushioned treadmill can easily receive electrical signals from the belt vibration sensor during use, allowing the device to easily adjust its output torque in real time based on the sensor information. This enables the device to reduce lift in real time when the user lands, avoiding resonance and improving the treadmill's performance. Furthermore, an effective locking structure is incorporated within the device, allowing for easy locking of the motor shaft when the device is raised to a designated height, improving its stability and resulting in a better user experience. Specific details are as follows:

[0021] 1. The motor controller is fixed on the left side of the motor body by the positioning block and the motor body. The motor controller can capture and receive the electrical signals generated by the sensors inside the treadmill. The device can adjust the output torque of the motor body in real time according to the information transmitted by the sensor. When the operator runs and pedals on the treadmill, the device can reduce the lift in real time to avoid resonance caused by the interaction between the lift and the pedaling force. At the same time, the plane bearing and O-ring support and protect the second support plate, absorb the vibration generated during the rotation of the second support plate, and reduce the noise generated by the device operation.

[0022] 2. The second limiting rod, together with the motor body, fixes the support frame on the upper side of the motor shaft body, so that the motor shaft body can effectively push the support block to rotate inside the support frame during rotation. At this time, the rotating support block and the air intake fan can effectively draw the cold air outside the support frame into the interior of the support frame and blow it onto the upper surface of the motor body to cool down the high temperature generated by the motor body during operation. However, the high temperature inevitably affects the safety of the device.

[0023] 3. The micro drive motor, in conjunction with the second drive disc, pushes the drive rod and the first drive disc to rotate on the left side of the reducer body. This causes the drive rod to push the locking block connected to its upper side to move to the right along the guide rod and engage with the first support disc. This facilitates locking the first support disc when the device is raised to the designated position, reduces the energy consumption of the motor body, and improves the stability of the device.

[0030] 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.

[0031] Please see Figure 1-5 This utility model provides a technical solution: a lifting motor for a treadmill with track cushioning, comprising a reducer body 1, a motor body 2, a first limiting rod 3, a positioning block 4, a motor controller 5, a support frame 6, a second limiting rod 7, a support block 8, an air intake fan blade 9, a motor shaft body 10, a first support plate 11, a locking block 12, a guide rod 13, a drive rod 14, a first drive plate 15, a second drive plate 16, a micro drive motor 17, a second support plate 18, a plane bearing 19, an O-ring 20, a lead screw 21, an outer cylinder 22, and a third limiting rod 23.

[0032] Specifically, such as Figure 1 , Figure 2 and Figure 3As shown, before using the device, the motor body 2 is installed on the left side of the reducer body 1. At this time, the first limiting rod 3 is rotated so that the first limiting rod 3 rotating downward can effectively fix the motor body 2 on the left side of the reducer body 1. At this time, the motor body 2 is started, so that the motor body 2 drives the first support plate 11 connected to its lower side to rotate inside the reducer body 1. At this time, the reducer body 1 decelerates the high-speed rotational force generated by the motor body 2, converting the high-speed rotation into a low-speed, high-torque output. At this time, the gear set set inside the reducer body 1 pushes the second support plate 18 to rotate at low speed on the right side of the reducer body 1. This causes the second support plate 18 to drive the lead screw 21 passing through it to rotate and displace inside the outer cylinder 22 and the third limiting rod 23. The plane bearings 19 set on the upper and lower sides of the second support plate 18 support and guide the rotation of the second support plate 18, making the second support plate 18 more stable in pushing the lead screw 21 to rotate on the right side of the reducer body 1, reducing the axial shaking generated by the second support plate 18 and the lead screw 21 during rotation.

[0033] Meanwhile, the O-ring 20 on the outer side of the planar bearing 19 fills the gap between the second support plate 18 and the reducer body 1, so that the O-ring 20 can buffer the vibration generated by the operation of the planar bearing 19 and the second support plate 18, and reduce the noise generated by the collision between the second support plate 18 and the reducer body 1. At the same time, the motor controller 5 is installed on the inner side of the positioning block 4. At this time, due to the snap-fit ​​connection structure between the positioning block 4 and the motor controller 5, the positioning block 4 can effectively fix the motor controller 5 on the left side of the motor body 2. At this time, the motor controller 5 captures and receives the electrical signals generated by the sensors inside the treadmill, so that the device can easily adjust the output torque of the motor body 2 in real time according to the information transmitted by the sensors. This makes it easier for the operator to reduce the lift in real time when running and stepping on the treadmill to avoid resonance caused by the interaction between the lift and the stepping force, thus improving the performance of the device.

[0034] Specifically, such as Figure 3 , Figure 4 and Figure 5As shown, before using the device, the support frame 6 is installed on the upper side of the motor body 2. The second limiting rod 7, which passes through the outer side of the rotating support frame 6, is then connected to the support frame 6 and the motor body 2 via a threaded connection. The downward rotation of the second limiting rod 7 effectively connects the support frame 6 and the motor body 2 together. Furthermore, the engaging connection between the support block 8 and the motor shaft body 10 ensures a stable connection between the support block 8 inside the support frame 6 and the motor shaft body 10 on the upper side of the motor body 2. During operation, the motor body 2 drives the motor shaft body 10 on its upper side. The motor body 2 rotates on its upper side. Due to the rotating connection structure between the support block 8 and the support frame 6, the motor shaft body 10 can effectively push the support block 8 connected to its upper side to rotate inside the support frame 6 during the rotation process. At this time, the support block 8 drives the air intake fan blade 9 connected to its outer side to rotate inside the support frame 6, so that the air intake fan blade 9 draws the cold air outside the support frame 6 into the support frame 6 and blows it onto the upper surface of the motor body 2 to cool down the high temperature generated by the operation of the motor body 2. This prevents the high temperature generated by the motor body 2 during the process from affecting the safety of the use of the motor body 2 and improves the stability of the device.

[0035] Simultaneously, during the use of the device, by activating the micro drive motor 17 located on the left side of the reducer body 1, the micro drive motor 17 drives the second drive disk 16 connected to its lower side to rotate on the left side of the reducer body 1. Due to the meshing connection structure between the second drive disk 16 and the first drive disk 15, the second drive disk 16 can effectively push the first drive disk 15 and the drive rod 14 to rotate on the left side of the reducer body 1 during rotation. Due to the threaded connection structure between the drive rod 14 and the locking block 12, the drive rod 14 can stably push the locking block 12 connected to its upper side during rotation. 2. When the device moves to the right, the sliding connection between the guide rod 13 and the reducer body 1 ensures that the locking block 12 is guided and limited by the guide rod 13 during the rightward movement. This prevents the locking block 12 from shifting position when driven to the right by the drive rod 14. At this time, the engaging connection between the locking block 12 and the first support plate 11 allows the rightward-moving locking block 12 to effectively lock the first support plate 11. This prevents the motor body 2 from maintaining a certain torque input when the device is raised to the specified height, thus improving the stability of the device while reducing energy consumption.
