Technical Field

[0001] This invention relates to a fitness equipment, and more particularly to an automatically folding fitness equipment. Background Technology

[0002] With the improvement of economic and technological levels, people's demands for quality of life are constantly increasing, and their attention to their health and body management is also rising. Therefore, various types of fitness equipment have emerged, among which integrated fitness equipment is more popular. However, because this type of fitness equipment usually includes a display screen and a base, its overall size is relatively large, requiring a lot of space, which leads to drawbacks such as difficulties in transportation, moving, and storage. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to provide an automatically folding fitness equipment, which aims to achieve a simple, reasonable and efficient product structure design, so as to facilitate the transportation, handling and storage of the product and reduce the limitations of the product's use.

[0004] To address this issue, the present invention provides an automatically folding fitness equipment, comprising: a motor drive assembly, a worm gear assembly, a triangular support, and a folding base. The folding base includes a first base and a second base. The second base is connected to one end of the first base via a hinge structure, and the other end of the first base is rotatably connected to the triangular support. The motor drive assembly and the worm gear assembly are disposed within the triangular support and connected to the first base. An auxiliary wheel is disposed on the outer side of the second base away from the first base. When the folding base is fully unfolded, the auxiliary wheel's ground clearance is greater than a preset ground clearance. During the folding process, the motor drive assembly controls the rope to tighten, and simultaneously, through the worm gear assembly... The worm gear assembly drives the first base to rotate and fold upwards. At this time, the second base, under the action of the hinge structure and the auxiliary wheel, follows the first base to fold until the second base and the first base are folded to one side of the triangular bracket. During the unfolding process, the motor drive assembly controls the rope to relax, and at the same time, the worm gear assembly drives the first base to rotate downwards and unfold. After the unfolding begins, the auxiliary wheel of the second base moves away from the first base in contact with the ground, so that the second base unfolds synchronously with the first base until the first base and the second base reach the fully unfolded state. At this time, the first base and the second base are on the same horizontal line.

[0005] A further improvement of the present invention is that the motor drive assembly includes a geared motor, a first guide wheel assembly, and a second guide wheel assembly. The first guide wheel assembly is symmetrically arranged on both sides of the output shaft of the geared motor, and the second guide wheel assembly is symmetrically arranged on one end of the geared motor near the first base. The bottom of the triangular bracket near the first base is provided with a cable outlet hole, and the position of the cable outlet hole corresponds to the position of the second guide wheel assembly. The rope is wound around the output shaft of the geared motor, extends from both sides and connects to the first guide wheel assembly, and then passes through the first guide wheel assembly, the second guide wheel assembly, and the cable outlet hole in sequence to connect to the first base.

[0006] A further improvement of the present invention is that the first guide wheel assembly and the second guide wheel assembly each include two adjacent and parallel guide wheels, and the rope is disposed between the two guide wheels; a protective cover is provided above the output shaft of the reduction motor.

[0007] A further improvement of the present invention is that the first base is provided with a rotating shaft connecting part on both sides of one end near the triangular bracket, and the first base is rotatably connected to the worm gear assembly through the rotating shaft and the rotating shaft connecting part.

[0008] A further improvement of the present invention is that an inlet hole is provided in the middle of one end of the first base near the triangular bracket, and the position of the inlet hole corresponds to the position of the outlet hole.

[0009] A further improvement of the present invention is that a plurality of third guide wheel assemblies are symmetrically arranged in the first base, and the rope passes through the outlet hole and the inlet hole in sequence and is connected to the third guide wheel assembly.

[0010] A further improvement of the present invention is that the positions of at least two of the third guide wheel assemblies correspond to the positions of the two wire inlets respectively; the positions of at least two of the third guide wheel assemblies are arranged on the inner side of the end of the first base near the second base, and are arranged next to the hinge structure.

[0011] A further improvement of the present invention is that one side of the third guide wheel assembly also includes a rope limiting member.

[0012] A further improvement of the present invention is that the preset ground clearance is 0.5 mm to 0.8 mm.

[0013] A further improvement of the present invention is that the triangular support is an isosceles triangular support, and the base angle of the isosceles triangular support is in the range of 71°~74°.

[0014] Compared with existing technologies, the advantages of this invention are as follows: During the folding process, the motor drive assembly controls the rope to tighten, and simultaneously drives the first base to rotate upwards and fold through the worm gear assembly. At this time, the second base, under the action of the hinge structure and auxiliary wheel, follows the first base to fold until the second base and the first base are completely folded to one side of the triangular bracket. This allows for the folding of the first and second bases based on a single-stage drive, facilitating product transportation, handling, and storage, and reducing product usage limitations. Furthermore, during the unfolding process, the motor drive assembly controls the rope to loosen, and simultaneously drives the first base to rotate downwards and unfold through the worm gear assembly. After unfolding begins, the auxiliary wheel of the second base moves away from the first base, thus enabling the second base to unfold synchronously with the first base until both bases are fully unfolded, at which point they are on the same horizontal line. The structure of this invention is reasonable and efficient, the implementation process is simple and reliable, and the design is highly user-friendly. Attached Figure Description

[0025] The preferred embodiments of the present invention will now be described in further detail with reference to the accompanying drawings.

[0026] like Figures 1 to 7As shown, this embodiment provides an automatically folding fitness equipment, including: a motor drive assembly 1, a worm gear assembly 2, a triangular support 3, and a folding base. The folding base includes a first base 4 and a second base 5. The second base 5 is connected to one end of the first base 4 via a hinge structure 6, and the other end of the first base 4 is rotatably connected to the triangular support 3. The motor drive assembly 1 and the worm gear assembly 2 are disposed within the triangular support 3 and connected to the first base 4. An auxiliary wheel 7 is disposed on the outer side of the second base 5 away from the first base 4. When the folding base is fully unfolded, the height of the auxiliary wheel 7 off the ground is greater than a preset height of 0. During the folding process, the motor drive assembly 1 controls the rope to tighten, and simultaneously, through the worm gear assembly 2... The worm gear assembly 2 drives the first base 4 to rotate upward and fold. At this time, the second base 5, under the action of the hinge structure 6 and the auxiliary wheel 7, follows the first base 4 to fold until the second base 5 and the first base 4 are folded to one side of the triangular bracket 3. During the unfolding process, the motor drive assembly 1 controls the rope to relax, and at the same time, the worm gear assembly 2 drives the first base 4 to rotate downward and unfold. After the unfolding begins, the auxiliary wheel 7 of the second base 5 moves away from the first base 4 in contact with the ground, so that the second base 5 and the first base 4 unfold synchronously until the first base 4 and the second base 5 reach the fully unfolded state. At this time, the first base 4 and the second base 5 are on the same horizontal line.

[0027] It is worth noting that the folding base described in this embodiment includes a first base 4 and a second base 5 connected by the hinge structure 6, which allows the folding base to fold to one side of the triangular bracket 3, resulting in a smaller folded volume. Furthermore, even with two foldable bases (first base 4 and second base 5), this embodiment only requires a single-stage drive to achieve the automatic folding process. This single-stage drive refers to setting only the motor drive assembly 1 and the worm gear assembly 2 between the triangular bracket 3 and the first base 4, without needing a second-stage worm gear or other drive structure between the first base 4 and the second base 5 to drive the movement of the second base 5. This is one of the design challenges of this embodiment.

[0028] To achieve the single-stage drive described above in this embodiment, based on the worm gear assembly 2, a matching motor drive assembly 1, a triangular bracket 3, and an auxiliary wheel 7 are also designed. That is, through the specific structure of the motor drive assembly 1 and the structural details of the triangular bracket 3 and the auxiliary wheel 7, the overall technical solution can achieve single-stage drive for foldable and unfoldable control, while ensuring the product's stability and reliability. Specifically, when the folding base is fully unfolded, the auxiliary wheel 7 is at a preset ground clearance, which is greater than 0. In this state, there is a height difference between the auxiliary wheel 7 and the supporting ground of the first base 4 and the second base 5, and it does not directly contact the ground. Figure 2 As shown, this ensures the stability of the fitness equipment and prevents it from shifting. During the unfolding process, the motor drive assembly 1 controls the rope to relax, while the worm gear assembly 2 drives the first base 4 to rotate downwards and unfold. After unfolding begins, due to the triangular support 3, the second base 5 unfolds at a certain angle, causing the auxiliary wheel 7 to touch the ground. After the auxiliary wheel 7 of the second base 5 contacts the ground, it moves away from the first base 4, thus enabling the second base 5 and the first base 4 to unfold synchronously. These factors work together to achieve a clever single-stage drive. The structural design of this embodiment is reasonable and efficient, the implementation process is simple and reliable, and the degree of humanized design is high.

[0029] It is also worth noting that the preset ground clearance of the auxiliary wheel 7 in this embodiment is not necessarily better the higher it is, as too high a height will affect the smoothness of the unfolding of the second base 5. Preferably, the preset ground clearance in this embodiment is 0.5 mm to 0.8 mm, and the triangular support 3 is preferably an isosceles triangular support with a base angle range of 71° to 74°. This specific range of values ​​is not arbitrarily designed, nor is it designed based on a single structure. Rather, it is a targeted optimization for the coordinated work of the overall structure, so as to better ensure the smoothness of the single-stage drive and unfolding process of the fitness equipment, while making the overall structure more stable and reliable.

[0030] like Figure 3 and Figure 4As shown, the motor drive assembly 1 in this embodiment includes a geared motor 101, a first guide wheel assembly 102, and a second guide wheel assembly 103. The first guide wheel assembly 102 is symmetrically arranged on both sides of the output shaft of the geared motor 101, and the second guide wheel assembly 103 is symmetrically arranged at one end of the geared motor 101 near the first base 4. The bottom of the triangular bracket 3 near the first base 4 is provided with a cable outlet hole 301, and the position of the cable outlet hole 301 corresponds to the position of the second guide wheel assembly 103. A rope is wound around the output shaft of the geared motor 101. Preferably, there are two geared motors 101, and the two geared electrodes 101 are arranged side by side, with their output shafts located at one end near the first base 4. The rope extends from the output shafts of the two geared motors 101 and connects to the first guide wheel assembly 102, and then passes through the first guide wheel assembly 102, the second guide wheel assembly 103, and the cable outlet hole 301 in sequence to connect to the first base 4, thereby realizing the cable outlet and control.

[0031] Preferably, in this embodiment, both the first guide wheel assembly 102 and the second guide wheel assembly 103 include two adjacent and parallel guide wheels. The rope is inserted between these two guide wheels, thereby ensuring that the rope is not misaligned and that good directionality is maintained. A protective cover 104 is provided above the output shaft of the reduction motor 101. The shape of the protective cover 104 matches the shape of the output shaft of the reduction motor 101, thereby effectively protecting the reduction electrode 101 and effectively preventing problems such as entanglement between the rope and other structures.

[0032] In this embodiment, the first base 4 is provided with a rotating shaft connecting part 402 on both sides near the end of the triangular bracket 3. The first base 4 is rotatably connected to the worm gear assembly 2 through the rotating shaft and the rotating shaft connecting part 402. The rotating shaft passes through the worm gear assembly 2 and is connected to the rotating shaft connecting part 402 so as to drive the rotation of the first base 4.

[0033] like Figures 5 to 7As shown, in this embodiment, the first base 4, in conjunction with the triangular bracket 3, has a cable inlet hole 401 at the middle of one end near the triangular bracket 3. The positions of the cable inlet hole 401 correspond to the positions of the cable outlet hole 301. A plurality of third guide wheel assemblies 403 are symmetrically arranged within the first base 4. The rope passes sequentially through the cable outlet hole 301 and the cable inlet hole 401 and connects to the third guide wheel assemblies 403. At least two of the third guide wheel assemblies 403 are positioned corresponding to the positions of two cable inlet holes 401 to facilitate cable entry. At least two of the third guide wheel assemblies 403 are located on the inner side of the first base 4 near the second base 5 and are positioned next to the hinge structure 6 to ensure more reliable structural force application next to the hinge structure 6. Preferably, as... Figure 7 As shown, unlike the structure of the first guide wheel assembly 102 and the second guide wheel assembly 103, the third guide wheel assembly 403 in this embodiment also includes a rope limiting member 404 on one side. The rope passes through the space between the third guide wheel assembly 403 and the rope limiting member 404, thereby preventing the rope from being misaligned by the rope limiting member 404 and providing a fixed-direction guiding effect by the third guide wheel assembly 403.

[0034] The above description, in conjunction with specific preferred embodiments, provides a further detailed explanation of the present invention. It should not be construed that the specific implementation of the present invention is limited to these descriptions. For those skilled in the art, various simple deductions or substitutions can be made without departing from the concept of the present invention, and all such modifications and substitutions should be considered within the scope of protection of the present invention.
