Description

Technical Field

[0001] This invention belongs to the technical field of treadmills, and in particular relates to an electric folding treadmill with lifting function and its operating method. Background Technology

[0002] Treadmills, as the most popular home aerobic fitness equipment, have become an important part of modern family fitness. With the increasing health awareness and the demand for efficient use of living space, home treadmills not only need to have good exercise performance and a comfortable running experience, but also need to save as much space as possible when not in use.

[0003] However, traditional treadmills generally suffer from large footprints and inconvenient storage. Existing foldable treadmills mostly use self-locking hydraulic rods for folding and locking, requiring manual operation for both folding and unfolding, which is not user-friendly for some female users. There are also some electric folding treadmills; some require a pin mechanism to switch between lifting and folding states; some use two lifting motors to achieve lifting and folding functions separately, resulting in complex programs, structures, and high costs; and some use a single lifting motor, with the motor push rod extending and retracting to achieve folding and lifting respectively, but due to structural limitations, the achievable lifting angle is only about 4 degrees, resulting in a shallow lifting incline. Therefore, we provide an electric folding treadmill with lifting function and its operating method to solve the above problems. Summary of the Invention

[0004] The purpose of this invention is to provide an electric folding treadmill with lifting function and its operation method. By using the lifting motor, lifting frame and folding linkage in combination, the drive system of the treadmill is simplified, the manufacturing cost is reduced, the electrical failure points are reduced, and the overall reliability of the machine is improved.

[0005] To solve the above-mentioned technical problems, the present invention is achieved through the following technical solution:

[0006] This invention relates to an electric folding treadmill with a lifting function, comprising a main frame, a running board mounted on the inner side of the main frame, a running belt mounted on the running board, rollers mounted on the inner side of the main frame to the left and right of the running board, and a drive motor mounted on the inner side of the main frame to the left of the running board, wherein the drive motor is connected to the adjacent rollers for transmission; a base frame is provided at the lower left of the main frame, and a handrail is fixed at the upper end of the base frame to the left of the main frame; a lifting and folding assembly is provided inside the base frame, the lifting and folding assembly including a lifting frame, folding linkages and a lifting motor; two sets of lifting frames are provided on the inner side of the base frame, and are arranged symmetrically front and back; two folding linkages are provided, and are respectively close to the side of the adjacent lifting frames, wherein the middle part of the folding linkage is bent upward and protruding; the lifting motor is located between the two sets of folding linkages and is used to control the lifting of the main frame.

[0007] The invention is further configured such that a second fixed beam is installed on the inner side of the base frame to the right of the lifting frame, and a first fixed beam is installed on the inner side of the base frame to the right of the second fixed beam, wherein the lifting motor is located between the first fixed beam and the second fixed beam.

[0008] The invention is further configured such that the tail end of the lifting motor is hinged to the second fixed beam, and a reinforcing beam located below the running belt is fixed inside the main beam to the right of the first fixed beam. A top fixing plate is fixed in the middle of the reinforcing beam, and the top fixing plate is hinged to the telescopic end of the lifting motor. The right end of the folding connecting rod is hinged to the first fixed beam.

[0009] The invention is further configured such that top connectors are fixed on the lower side wall of the main frame to the left of the reinforcing beam, corresponding to the position of the hoisting frame, and the two sets of top connectors are respectively hinged to the upper end of the corresponding hoisting frame.

[0010] The invention is further configured such that a crossbeam is fixed between the two sets of lifting frames located to the left of the second fixed beam, and the left ends of the folding connecting rods are all hinged to the crossbeam.

[0011] The invention is further configured such that the lower ends of both sets of lifting frames are rotatably connected to auxiliary wheels, and the right side of the lower side of the main frame is fixed with rollers.

[0012] The present invention also provides a method for operating an electric folding treadmill with a lifting function, which is operated according to the following steps:

[0013] S1: When the main frame is in a flat position, the operator can control the drive motor through the instrument panel, which can drive the running belt to move, so the operator can run.

[0014] S2: When it is necessary to control the slope of the main frame, the lifting motor can be controlled to gradually increase the slope of the treadmill, and the entire lifting frame will gradually stand up. When the lifting frame reaches the lifting limit, the slope of the main frame is 8°, and the lifting frame will maintain this posture.

[0015] S3: When the entire treadmill needs to be folded, the lifting motor continues to work via the dashboard control. The main frame will start to rotate around the hinge between the top connector and the lifting frame, thus lifting the roller on the right end of the main frame off the ground until the main frame is parallel to the lifting frame. At this time, the lifting motor reaches its maximum stroke, and the folding action is completed.

[0016] The present invention has the following beneficial effects: The present invention drives the lifting frame and the folding linkage with the same lifting motor. With the asymmetrical geometric structure of the upward bending protrusion in the middle of the folding linkage, the sequential action of "lifting first and then folding" is realized. The user only needs to operate the instrument panel to control the lifting motor to work continuously. The motor push rod first pushes the main frame to complete the incline lifting from 0° to 8°, and then automatically switches to the folding mode, so that the main frame flips upward with the top connector as the center until it is upright. This integrated linkage design does not require an additional motor or switching mechanism, which simplifies the drive system of the treadmill, reduces manufacturing costs, reduces electrical failure points, and improves the overall reliability of the machine.

[0026] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0027] Please see Figures 1 to 6 This invention relates to an electric folding treadmill with a lifting function, comprising a main frame 1, a running board 103 mounted on the inner side of the main frame 1, a running belt 101 sleeved on the running board 103, rollers 105 mounted on the inner side of the main frame 1 to the left and right of the running board 103, and a drive motor 104 mounted on the inner side of the main frame 1 to the left of the running board 103, wherein the drive motor 104 is connected to the adjacent rollers 105 for transmission; a base frame 2 is provided at the lower left of the main frame 1, and the upper end of the base frame 2 located to the left of the main frame 1 is fixed. The frame 3 is fixed, and the base frame 2 is equipped with a lifting and folding assembly. The lifting and folding assembly includes a lifting frame 4, a folding link 5, and a lifting motor 6. Two sets of lifting frames 4 are set inside the base frame 2 and are arranged symmetrically front and back. Two folding links 5 are set and are located close to the sides of the adjacent lifting frames 4. The middle part of the folding link 5 is bent and protruded upward. The lifting motor 6 is located between the two sets of folding links 5 and is used to control the lifting of the main frame 1.

[0028] The treadmill operates in three phases:

[0029] Phase 1: The entire treadmill is initially in a horizontal position;

[0030] Second stage: Lifting. At this time, the lifting motor 6 is controlled to work. The push rod at the telescopic end of the lifting motor 6 extends, thereby controlling the left end of the main frame 1 to gradually lift upward, so that the incline of the treadmill gradually increases. Since the folding link 5 is hinged to the crossbeam 401 on the lifting frame 4, the entire lifting frame 4 will gradually stand up. When the lifting frame 4 reaches the lifting limit, the incline of the main frame 1 is 8°. At this time, the lifting frame 4 is still in an inclined state, and there is still a mutually restrictive force relationship between the lifting frame 4 and the folding link 5. The roller 102 at the lower end of the lifting frame 4 can no longer slide to the right, and the lifting frame 4 maintains this posture.

[0031] The third stage is folding. An instrument panel for controlling the drive motor 104 and the lifting motor 6 can be installed on the support frame 3. The lifting motor 6 continues to work through the control panel. Since the lifting frame 4 and the folding linkage 5 are in a fixed state of mutual constraint, the main frame 1 will start to rotate around the hinge between the top connector 108 and the lifting frame 4. As a result, the roller 102 on the right end of the main frame 1 will be lifted off the ground until the main frame 1 is parallel to the lifting frame 4. At this time, the mutual constraint between the lifting frame 4 and the folding linkage 5 is released, and the telescopic end of the lifting motor 6 can continue to work. The main frame 1 will rotate together with the lifting frame 4 until the main frame 1 is parallel to the support frame 3 and the tilt angle is the same. At this time, the lifting motor 6 reaches its maximum stroke, and the folding action is completed.

[0032] Example 1, according to Figure 2 and Figure 3 It can be seen that a second fixed beam 202 is installed on the inner side of the base frame 2 to the right of the lifting frame 4, and a first fixed beam 201 is installed on the inner side of the base frame 2 to the right of the second fixed beam 202. The lifting motor 6 is located between the first fixed beam 201 and the second fixed beam 202. The tail of the lifting motor 6 is hinged to the second fixed beam 202. A reinforcing beam 106 is fixed on the inner side of the main beam to the right of the first fixed beam 201, located below the running belt 101. A top fixing plate 107 is fixed in the middle of the reinforcing beam 106. The top fixing plate 107 is hinged to the telescopic end of the lifting motor 6. Top connecting parts 108 are fixed on the lower side wall of the main frame 1 to the left of the reinforcing beam 106, corresponding to the position of the lifting frame 4. The two sets of top connecting parts 108 are respectively hinged to the upper end of the corresponding lifting frame 4. The right end of the folding connecting rod 5 is hinged to the first fixed beam 201.

[0033] In this embodiment, a reinforcing beam 106 is welded to the inner side of the main frame 1 below the running belt 101, which greatly improves the bending resistance of the bottom of the main frame 1. The frame will not be twisted or deformed during the lifting and pushing process. The upper end of the lifting frame 4 is hinged to the top connector 108. This hinge point is the only rotation fulcrum in the entire lifting and folding process. The entire hinge structure is stress-distributed, and the weld is less likely to crack during long-term climbing and lifting.

[0034] Example 2, based on Example 1, according to Figure 1 and Figure 2 It can be seen that a crossbeam 401 is fixed between the two sets of lifting frames 4 located to the left of the fixed beam 202. The left end of the folding connecting rod 5 is hinged to the crossbeam 401. The lower ends of the two sets of lifting frames 4 are rotatably connected to auxiliary wheels 402. Rollers 102 are fixed on the right side of the lower side of the main frame 1.

[0035] In this embodiment, when the treadmill is placed horizontally, the auxiliary wheel 402 and the roller 102 on the right end of the main frame 1 simultaneously contact the ground, forming a four-point stable support for the entire machine.

[0036] Example 3: The present invention also provides an operating method for an electric folding treadmill with a lifting function, which is operated according to the following steps:

[0037] S1: When the main frame 1 is in a flat position, the operator can control the drive motor 104 through the instrument panel, which can drive the running belt 101 to move, so the operator can run.

[0038] S2: When it is necessary to control the slope of the main frame 1, the lifting motor 6 can be controlled to work, so that the slope of the treadmill gradually increases, and the lifting frame 4 will gradually stand up. When the lifting frame 4 reaches the lifting limit, the slope of the main frame 1 is 8°, and the lifting frame 4 will maintain this posture.

[0039] S3: When the entire treadmill needs to be folded, the lifting motor 6 is controlled by the dashboard to continue working. The main frame 1 will start to rotate around the hinge between the top connector 108 and the lifting frame 4. As a result, the roller 102 on the right end of the main frame 1 will be lifted off the ground until the main frame 1 is parallel to the lifting frame 4. At this time, the lifting motor 6 reaches its maximum stroke and the folding action is completed.
