[0026] The preferred embodiments of the present application will be further described in detail below with reference to the accompanying drawings.

[0027] As shown in Figures 1 to 7, this embodiment provides an automatically folding fitness equipment, including: a motor drive assembly 1, a worm gear assembly 2, a triangular bracket 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 through a hinge structure 6, and the other end of the first base 4 is rotatably connected to the triangular bracket 3; the motor drive assembly 1 and the worm gear assembly 2 are arranged in the triangular bracket 3 and connected to the first base 4; an auxiliary wheel 7 is provided on the outer side of the end of the second base 5 away from the first base 4. When the folding base is fully unfolded, the auxiliary wheel 7 is at a preset ground clearance height greater than 0; during the folding process, the motor drive assembly 1 controls the rope to be tightened, At the same time, the worm gear assembly 2 drives the first base 4 to rotate and fold upward. 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 in turn; during the unfolding process, the motor drive assembly 1 controls the rope to relax, and at the same time drives the first base 4 to rotate and unfold downward through the worm gear assembly 2. After the unfolding begins, the auxiliary wheel 7 of the second base 5 contacts the ground and moves away from the first base 4, thereby making the second base 5 and the first base 4 unfold synchronously until the first base 4 and the second base 5 reach a fully unfolded state. At this time, the first base 4 and the second base 5 are on the same horizontal line.

[0028] It is worth noting that the folding base of this embodiment includes a first base 4 and a second base 5 connected by a hinge structure 6, so that the folding base can be folded to one side of the triangular bracket 3 so that the volume after folding is smaller; on this basis, even if two foldable bases, the first base 4 and the second base 5, are included, this embodiment only needs a single-stage drive to realize the automatic folding process; the single-stage drive means that only the motor drive component 1 and the worm gear component 2 are set between the triangular bracket 3 and the first base 4, and there is no need to set a second-stage worm gear or other driving 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 difficulties of this embodiment.

[0029] In order to realize the above-mentioned single-stage drive of this embodiment, this embodiment is further designed with a matching motor drive assembly 1, a triangular bracket 3 and an auxiliary wheel 7 on the basis of the worm gear assembly 2. That is to say, 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 realize the foldable and unfolding control of the single-stage drive and ensure the stability and reliability of the product. When the folding base is fully unfolded, the height of the auxiliary wheel 7 from the ground is a preset height above zero, which is greater than zero. That is, 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 the auxiliary wheel 7 does not directly contact the ground, as shown in Figure 2, to ensure the stability of the fitness equipment at this time and prevent it from shifting. During the unfolding process, the motor drive assembly 1 controls the rope to loosen, and at the same time drives the first base 4 to rotate downward and unfold through the worm gear assembly 2. After the second base 5 begins to unfold, due to the setting of the triangular bracket 3, the second base 5 will unfold at a certain angle so that the auxiliary wheel 7 touches the ground. After the auxiliary wheel 7 of the second base 5 contacts the ground, it moves away from the first base 4, thereby allowing the second base 5 to unfold synchronously with the first base 4. These factors work together to achieve an ingenious 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.

[0030] It's also worth noting that the preset height of the auxiliary wheels 7 in this embodiment is not necessarily higher, as a higher height will affect the smooth deployment of the second base 5. Preferably, the preset height in this embodiment is 0.5 mm to 0.8 mm. The triangular bracket 3 preferably utilizes an isosceles triangle bracket, with a base angle ranging from 71° to 74°. This specific range of values ​​employed in this embodiment is not arbitrary, nor is it based on a single design. Instead, it is optimized for the coordinated operation of the overall structure, ensuring smooth single-stage actuation and deployment of the fitness equipment while also making the overall structure more stable and reliable.

[0031] As shown in Figures 3 and 4, the motor drive assembly 1 of this embodiment includes a reduction 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 reduction motor 101, and the second guide wheel assembly 103 is symmetrically arranged at one end of the reduction motor 101 close to the first base 4. A wire outlet hole 301 is provided at the bottom of the side of the triangular bracket 3 close to the first base 4, and the position of the wire outlet hole 301 corresponds to the position of the second guide wheel assembly 103; the rope is wound around the output shaft of the reduction motor 101, and the number of reduction motors 101 is preferably two. The two reduction electrodes 101 are arranged in parallel, and their output shafts are arranged at one end close to the first base 4; the rope extends from the output shafts of the reduction motors 101 on both sides and is connected 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 wire outlet hole 301 in sequence to be connected to the first base 4, thereby realizing the rope outlet and control.

[0032] Preferably, the first guide wheel assembly 102 and the second guide wheel assembly 103 of this embodiment each include two adjacent and parallel guide wheels, and the rope is passed through and arranged between the two guide wheels, thereby ensuring that the rope is not misplaced and has good directionality; a protective cover 104 is provided above the output shaft of the reduction motor 101, and 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.

[0033] In this embodiment, the first base 4 is provided with a rotating shaft connecting part 402 on both sides of one end close to 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 to drive the rotation of the first base 4.

[0034] As shown in Figures 5 to 7 , in conjunction with the triangular bracket 3, the first base 4 of this embodiment is provided with a wire entry hole 401 in the middle of one end near the triangular bracket 3. The positions of the wire entry holes 401 correspond to the positions of the wire exit holes 301. A plurality of third guide wheel assemblies 403 are symmetrically arranged within the first base 4. Ropes pass through the wire exit holes 301 and the wire entry holes 401 in sequence and are connected to the third guide wheel assemblies 403. The positions of at least two third guide wheel assemblies 403 correspond to the positions of the two wire entry holes 401, respectively, to facilitate wire entry. At least two third guide wheel assemblies 403 are located on the inner side of one end of the first base 4 near the second base 5, and are located next to the hinge structure 6 to ensure more reliable structural forces acting near the hinge structure 6. Preferably, as shown in Figure 7, different from the structure of the first guide wheel assembly 102 and the second guide wheel assembly 103, one side of the third guide wheel assembly 403 of this embodiment also includes a rope limiter 404, and the rope passes through the space between the third guide wheel assembly 403 and the rope limiter 404, thereby preventing the rope from being misplaced through the rope limiter 404 and providing a fixed direction guiding effect through the third guide wheel assembly 403.

[0035] The above content is a further detailed description of the present application in conjunction with specific preferred embodiments, and the specific implementation of the present application cannot be considered to be limited to these descriptions. For ordinary technicians in the technical field to which the present application belongs, several simple deductions or substitutions can be made without departing from the concept of the present application, and all of them should be considered to fall within the scope of protection of the present application.
