[0035] The following is a clear and complete description of the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0036] like Figures 1 to 9 As shown, the present invention provides a multifunctional foldable treadmill with both running and rowing functions. It can be folded and stowed when not in use, reducing space requirements. Specifically, it includes a base 200, which serves as the exercise area for running and is configured to be foldable along its length. The base 200 includes a pedestal and a running belt. The base may also be provided with a drive mechanism for rotating the running belt. A control panel is provided at the top of the armrest mechanism 100 for adjusting the speed and displaying the treadmill status.

[0037] The utility model discloses a folding treadmill structure, which comprises a first support structure 110, a second support structure 120, a column 130, a sliding seat 140 and a pull handle assembly. The first support structure 110 is rotatably arranged on the base 200, so that the folding treadmill structure 100 can be rotated towards the base 200. The column 130 is slidably arranged on the first support structure 110. When the rowing function is used, the position of the column 130 is adjusted to adjust the front and back positions of the sliding seat 140, so as to meet the fitness needs of people of different heights. When folding and storing, the column 130 is slid towards the first support structure 110, which can effectively reduce the space occupation. The second support structure 120 is rotatably arranged at the end of the column 130 away from the first support structure 110, and has a supporting state and a folding state. Specifically, when the second support structure 120 is rotated away from the column 130 to abut on the ground or the base 200, it is in the supporting state. When the second support structure 120 is rotated towards the column 130 to be folded on the column 130, it is in the folding state. The sliding seat 140 is slidably arranged on the column 130 along the length direction of the column 130, and the sliding seat 140 is located at the side of the column 130 away from the base 200. The column 130 is slidably arranged on the first support structure 110, and the sliding seat 140 is slidably arranged on the column 130, which effectively increases the front and back position adjustment stroke of the sliding seat 140 relative to the first support structure 110.

[0038] When the rowing function is used, the first support structure 110 is rotated towards the base 200 until the side wall thereof abuts on the ground or the base 200. At this time, the column 130 is located above the base 200, and the central axis of the column 130 along the length direction and the central axis of the base 200 along the length direction are parallel. After the user slides the column 130 away from the first support structure 110 to a position suitable for his height, the second support structure 120 is rotated to be in the supporting state. At this time, the second support structure 120 and the first support structure 110 jointly provide support for the column 130. In the utility model, preferably, the second support structure 120 abuts on the ground when it is in the supporting state. In order to further reduce the space occupation of the treadmill, the base 200 needs to be folded before the rowing function is used. In this way, when the rowing function is used, the space occupation of the treadmill along the length direction of the base 200 can be reduced, and the support provided by the first support structure 110 and the second support structure 120 for the column 130 is also more stable.

[0039] When the treadmill is not used, the treadmill can be folded. First, the base 200 is folded along the length direction. Then, the second support structure 120 is rotated to the folding state towards the column 130, and the column 130 is slid to the folding state towards the first support structure 110. Finally, the first support structure 110 is rotated to the state that the side wall thereof abuts against the ground or the base 200, so that the folding of the treadmill is completed, the space occupied by the treadmill is reduced, and the folding is convenient and fast. When the running function is needed, the handrail structure 100 is only rotated to unfold away from the base 200, and then the base 200 is unfolded. When the running function is used, the second support structure 120 remains in the folding position.

[0040] As shown in Figure 2 and Figure 7 , in some embodiments, the second support structure 120 is in the support state, and the end thereof abutting against the ground or the base 200 is provided with an antiskid layer 125, so as to increase the friction between the second support structure 120 and the ground or the base 200, improve the stability when the rowing function is used, and avoid that the column 130 slides along with the sliding seat 140 when the user simulates the rowing function. The antiskid layer 125 can be made of soft plastic, and an antiskid groove can be further provided on the contact surface of the antiskid layer 125 in contact with the ground.

[0041] As shown in Figures 1 to 5 and Figure 9 , in some embodiments, the column 130 is provided with a first accommodating groove 131, and the second support structure 120 can be rotated into the first accommodating groove 131. When the second support structure 120 is in the folding state, it is folded in the first accommodating groove 131.

[0042] The column 130 is slidably arranged on the first support structure 110 through a structure such as a pulley sliding rail or a sliding rail block. In the utility model, preferably, the first accommodating groove 131 is arranged on the side wall of the column 130 close to the base 200, and the first sliding groove 133 and the second sliding groove 134 are arranged on the side wall of the column 130 close to the base 200 along the length direction thereof. The first sliding groove 133 and the second sliding groove 134 both extend to the ends of the column 130 along the length direction thereof and are respectively arranged on the two sides of the accommodating groove. The first support structure 110 is provided with a pulley matched with the first sliding groove 133 and the second sliding groove 134. It should be noted that the first sliding groove 133 and the second sliding groove 134 can be arranged on the surface of the column 130 close to the base 200, or can be arranged on the two side walls of the column 130 along the width direction of the base 200 or on the side wall of the column 130 away from the base 200. The arrangement position of the pulley is matched with the position of the sliding groove, and the sliding function thereof can be realized.

[0043] As the column 130 slides toward the first support structure 110, the second support structure 120 is retracted into the first receiving slot 131. When the first receiving slot 131 slides to the position of the pulley, it does not affect the continued sliding of the pulley, allowing the column 130 to continue sliding toward the first support structure 110. Therefore, the column 130 can be slid until it is completely above the first support structure 110, reducing the space occupied by the treadmill when it is folded.

[0044] In this embodiment, the first receiving groove 131 can also be positioned on the side wall of the column 130 away from the base 200. In this case, the second support structure 120 can be rotatably positioned at the end of the column 130 away from the first support structure 110. Specifically, a rotation shaft 132 is provided at the end of the column 130, and the second support structure 120 is rotatably positioned on the rotation shaft 132. The rotation angle around the rotation shaft 132 is preset to be greater than 180°, allowing the second support structure 120 to rotate until it abuts the base 200 or the ground. It is understood that the first receiving groove 131 is a groove-shaped structure provided on the side wall of the column 130. It can be configured to pass through or not pass through the column 130 along its depth direction, and can accommodate the second support structure 120 to achieve a storage function.

[0045] like Figures 1 to 7 and Figure 9 As shown, in some embodiments, the multifunctional foldable treadmill is further provided with a limiting structure to limit the position of the second support structure 120 when it is in the supporting state, so that the relative position between the second support structure 120 and the column 130 cannot change, allowing the second support structure 120 to provide stable support for the column 130. The limiting structure can be a limiting block, a limiting rod, a limiting pin, or other structure that can achieve its limiting function.

[0046] Specifically, the first receiving slot 131 is disposed on a side of the column 130 near the base 200. When the second support structure 120 is retracted into the first receiving slot 131, its longitudinal central axis is parallel to the longitudinal central axis of the column 130. Preferably, the maximum rotation angle of the second support structure 120 away from the first receiving slot 131 is preset to 100°-130°. This configuration allows the sidewalls of the second support structure 120 and the edge of the opening of the first receiving slot 131 to jointly form a limiting structure. For example, a rotation axis 132 is disposed at either end of the first receiving slot 131 along the longitudinal direction of the column 130. The first support structure 110 is rotatably mounted on the rotation axis 132 and can rotate about the rotation axis 132. The rotation angle of the second support structure 120 from the retracted state to the supporting state is set to between 100°-130°. The specific rotation angle can be set to any angle between 100°-130°, such as 100°, 110°, 120°, or 130°. When the second supporting structure 120 rotates to the supporting position, the side wall of the second supporting structure 120 that is away from the first receiving groove 131 in the retracted state abuts against the edge of the end opening of the first receiving groove 131 .

[0047] When in use, the user sits on the slide 140, and the first support structure 110 and the second support structure 120 jointly provide support force to the column 130 to support the user's body. Because the rotation angle of the second support structure 120 is greater than 90°, the second support structure 120 maintains a movement trend of continuing to rotate away from the first accommodating groove 131 under the action of the user's body weight, and cannot rotate further due to the restriction of the opening edge of the side wall of the first accommodating groove 131. The structure is simple and highly practical.

[0048] Preferably, in this embodiment, the second support structure 120 includes a support leg 121 and a connecting protrusion. The connecting protrusion is fixedly mounted at the top of the bracket and is further provided with a through-hole. A rotating shaft 132 is disposed within the first receiving slot 131 at the end away from the first support structure 110. The rotating shaft 132 extends through the through-hole, and the through-hole and the rotating shaft 132 are loosely fitted, allowing the second support structure 120 to rotate about the rotating shaft 132. It is understood that the connecting protrusion can also be fixedly connected to the rotating shaft 132, and the rotating shaft 132 can rotate relative to the column 130 along its circumference, without changing the position of the rotating shaft 132 during rotation. The limiting structure includes a step 123 formed between the connecting protrusion and the support leg 121. Specifically, the radius of the connecting protrusion is smaller than the outer diameter of the support leg 121. When the second support structure 120 is in the supporting state, the step 123 abuts the surface of the column 130. The steps 123 may be distributed along the circumference of the connecting protrusion, or may be provided on a side of the second supporting structure 120 away from the first receiving groove 131 and located between the connecting protrusion and the supporting leg 121 .

[0049] It can be understood that the connecting protrusion can also be two connecting lugs 122 arranged at the top of the support leg 121, the two connecting lugs 122 are symmetrically arranged, and through holes are arranged on both connecting lugs 122, and the two through holes are arranged opposite to each other, so that the rotating shaft 132 can pass through the two through holes at the same time, thereby realizing the rotational connection between the second support structure 120 and the rotating shaft 132.

[0050] like Figure 6 Figure 9 As shown, in some embodiments, the second support structure 120 is provided with a handle for pulling the second support structure 120 out of the first receiving slot 131. It should be understood that the handle is a structure that is easy for the user to grasp with the hand, making it easier for the user to pull the second support structure 120 out of the first receiving slot 131. For example, a groove-shaped structure or a grip structure is provided on the second support structure 120. In this embodiment, the second support structure 120 is provided with a mounting slot, and the handle is a crossbar 124 fixedly mounted in the mounting slot. When the second support structure 120 is in the retracted state, the crossbar 124 is pulled outward from the first receiving slot to rotate the second support structure 120 outward to the supporting state. This structure is simple and easy to use. It should also be understood that a motor can also be provided on the column 130 to drive the second support structure 120 to rotate, thereby achieving automatic expansion and contraction of the second support structure 120.

[0051] like Figures 1 to 3 and Figure 8As shown, in some embodiments, the first support structure 110 comprises a support frame, the support frame comprises a first frame 112, a second frame 113, a third frame 114 and a fourth frame 115, the first frame 112 and the second frame 113 are oppositely arranged, the third frame 114 and the fourth frame 115 are oppositely arranged, the first frame 112, the second frame 113, the third frame 114 and the fourth frame 115 jointly form a second accommodating groove 116, when the second support structure 120 is in the supporting state, the first frame 112, the second frame 113, the third frame 114 and the fourth frame 115 all abut the ground, and the support stability is strong when the rowing function is used. In order to further reduce the volume of the treadmill after folding, the size and shape of the second accommodating groove 116 are matched with the size and shape of the folded base 200, when the rowing function is used or the treadmill needs to be folded and stored, the treadmill base 200 is folded first, and the supporting structure 100 is rotated to the support frame abutting the ground, at this time, the folded base 200 is located in the second accommodating groove 116. It can be understood that in the present application, the external shape of the base 200 after folding is rectangular, therefore the shape of the second accommodating groove 116 is also rectangular, and the size of the second accommodating groove 116 is slightly larger than the size of the external shape of the base 200, so as to be matched with the base 200 and reduce the volume after folding, but setting the second accommodating groove 116 as other shapes can also achieve the present application, only the size of the second accommodating groove 116 needs to be set so that the size of the second accommodating groove 116 can accommodate the folded base 200.

[0052] As shown in Figures 1 to 3 and Figure 9 As shown in the present embodiment, the first support structure 110 further comprises a connecting seat 111, one end of the connecting seat 111 is fixedly arranged on the support frame, and the stand column 130 is slidably arranged on the end of the connecting seat 111 away from the support frame. When the folded base 200 is located in the second accommodating groove 116, the end of the connecting seat 111 away from the support frame is higher than the height of the folded base 200, so that the stand column 130 can slide to above the base 200 in the direction close to the first support structure 110, thereby reducing the volume of the treadmill after folding. Specifically, the support frame has opposite first and second ends, the first end of the support frame is rotatably arranged on the base 200 to realize the rotating function of the supporting structure 100 and realize the function switching and folding function of the multifunctional treadmill; the connecting seat 111 is fixedly arranged on the second end to prolong the adjusting stroke of the front and rear positions of the sliding seat 140.

[0053] In this embodiment, the length of the column 130 is further set to be less than or equal to the length of the first support structure 110 along the length direction of the base 200. After the treadmill is folded, the column 130 slides toward the first support structure 110 to above the folded base 200, and both ends of the column 130 do not protrude outside the first support structure 110 along its length direction, further reducing the space occupied by the treadmill after folding.

[0054] like Figures 1 to 3 and Figure 9 As shown, in some embodiments, the handle assembly is fixedly arranged on the end of the first support structure 110 away from the column 130, including a handle 150 and a resistance structure. The resistance structure includes a traction component 160 and a motor. The traction component 160 is wound around the output end of the motor, and the other end is fixedly connected to the handle 150. By adjusting the power of the motor, the resistance of the resistance structure can be infinitely adjusted, which is convenient and quick to use. It is understandable that the resistance structure can also adopt an elastic band, an internal magnetic flywheel group, a one-way hub brushless motor or a servo motor, etc.; its setting position can be set on the armrest mechanism 100 or on the base 200. Its actual setting position can be set according to the type of resistance structure adopted, as long as it can provide resistance to the handle 150.

[0055] The above further describes the present invention with the help of specific embodiments, but it should be understood that the specific description here should not be construed as limiting the essence and scope of the present invention. Various modifications made to the above embodiments by ordinary technicians in this field after reading this specification are all within the scope of protection of the present invention.
