Description

Technical Field

[0001] This utility model relates to the field of treadmill technology, and more specifically, to a treadmill with a one-button quick folding function. Background Technology

[0002] With the continuous improvement of living standards, people are paying more and more attention to physical exercise, and running is the simplest and most effective fitness method, making treadmills increasingly popular. Currently, most treadmills are not foldable. While some foldable treadmills are available on the market, they only allow for individual folding of the uprights or the instrument panel. Folding is achieved through simple manual pull pins, rotary knobs, or foot pedals, which are either cumbersome or strenuous, making them unfriendly to men or women with less strength. Existing foldable treadmills use sheet metal stamping and splicing, sheet metal snap-fit, or sheet metal with pull pin locking to achieve folding. Sheet metal stamping and welding result in significant deformation, making process control and dimensional measurement during production very difficult. Even minor dimensional changes at the folding position can be amplified due to the approximately one-meter distance between the folding point and the instrument panel's position, leading to inconsistencies in the wobbling of the left and right uprights. This often results in inconsistent production, with low batch production efficiency. Although die casting has been used to reduce the difficulty of dimensional control caused by sheet metal splicing and welding, the folding of the column and instrument still uses a linkage and eccentric mechanism to unlock the pin, and the direction of the pin is L-shaped with the column. This method has drawbacks such as complex structure, high cost, and difficulty in repair when failure occurs. Therefore, a treadmill with a one-button quick folding function is provided to solve the above problems. Utility Model Content

[0016] This utility model discloses a treadmill with a one-button quick-folding function. By pressing the unlocking component forcefully, the unlocking component causes the first pin to disengage from the engagement with the second limiting groove on the fixed seat, allowing the rotating seat to rotate relative to the fixed seat. This enables the control support assembly to fold relative to the upright. Simultaneously, the rotation of the rotating seat causes the pull rope to move, which in turn causes the second pin to disengage from the engagement with the first limiting groove on the running component. This allows the rotating component to rotate relative to the running component, enabling the upright to fold synchronously relative to the running component. This achieves the one-button quick-folding function of the treadmill, effectively solving the problem of the cumbersome and laborious folding process of existing treadmills.

Specifically, the lifting mechanism 114 includes a lifting drive device 1141 and a lifting frame 1142. The lifting drive device 1141 is disposed through the front cavity of the support body 1111 and is electrically connected to the circuit board 112. The lifting frame 1142 is movably disposed below the support body 1111 and is connected to the lifting drive device 1141. The lifting drive device 1141 drives the lifting frame 1142 to rotate relative to the support body 1111, thereby realizing the slope adjustment operation of the support mechanism 111. Preferably, the lifting drive device 1141 is an electric push rod.

[0034] Please see Figures 1-5As shown, in this embodiment, the control bracket assembly 13 includes a control bracket body 131 and a mobile phone holder 132. The control bracket body 131 can be rotatably folded and mounted on the column 12 via a folding unlocking component 14 and is electrically connected to the circuit board 112 via a communication connection line 15. The control bracket body 131 allows the user to easily grip it while simultaneously setting the functions of the running component 11. The mobile phone holder 132 is mounted on the control bracket body 131, allowing the user to easily place their mobile phone on the control bracket assembly 13.

Specifically, the control bracket body 131 uses existing technology, so its specific structure and working process will not be described in detail here, as long as it meets the requirements of this application.

[0035] Please see Figure 2 , Figure 3 , Figure 4 and Figure 6 As shown, in this embodiment, the folding unlocking assembly 14 includes a first unlocking mechanism 141, a second unlocking mechanism 142, and a pull rope 143.

The second unlocking mechanism 142 is located at the connection between the column 12 and the running assembly 11, enabling the column 12 to fold relative to the running assembly 11. The pull rope 143 is movably inserted through the column 12, with its two ends connected to the first unlocking mechanism 141 and the second unlocking mechanism 142, respectively. The first unlocking mechanism 141 synchronously drives the second unlocking mechanism 142 to move via the pull rope 143, thereby enabling the control support assembly 13 to rotate and fold relative to the column 12 while the column 12 also rotates and folds relative to the running assembly 11. Specifically, the pull rope 143 is a high-strength rope; preferably, the pull rope 143 is a steel cable.

[0036] Please see Figure 6 and Figure 7As shown, in this embodiment, the first unlocking mechanism 141 includes a fixed base 1411, a rotating base 1412, a first pin 1413, an unlocking member 1414, and a first elastic member 1415; the fixed base 1411 is fixedly mounted on the upper end of the column 12; the rotating base 1412 is rotatably connected to the fixed base 1411 and fixedly connected to the control bracket assembly 13; the first pin 1413 is movably disposed through the rotating base 1412 and can be detachably engaged with the fixed base 1411; the unlocking member 1414 is drively connected to the first pin 1413.

When the first pin 1413 disengages from the fixed seat 1411, the control bracket assembly 13 can rotate and fold relative to the column 12. The first elastic element 1415 is disposed between the inner wall of the rotating seat 1412 and the first pin 1413. It provides a restoring force to the first pin 1413, so that the first pin 1413 returns to its initial position and engages with the fixed seat 1411.

[0037] Please see Figure 7 As shown, specifically, a pivot pin 14111 is provided on the fixed base 1411, and the rotating base 1412 is rotatably connected to the fixed base 1411 via the pivot pin 14111; the fixed base 1411 is also provided with a second limiting groove 14112, the position of the second limiting groove 14112 corresponding to the position of the first pin 1413, and the first pin 1413 can be detachably engaged in the second limiting groove 14112, thereby realizing the fixed connection between the control bracket assembly 13 and the column 12. Specifically, the first elastic element 1415 is a spring.

[0038] Please see Figure 6 and Figure 8As shown, in this embodiment, the second unlocking mechanism 142 includes a rotating member 1421, a guide seat 1422, a second pin 1423, and a second elastic member 1424. The rotating member 1421 is rotatably disposed in the rotating hole 11111 and fixedly connected to the column 12. The guide seat 1422 is disposed below the rotating member 1421 and fixedly disposed on the lower end of the column 12, and can rotate relative to the support mechanism 111. The second pin 1423 is movably disposed through the guide seat 1422 and can engage with the support mechanism 111. The first limiting groove 11112 engages with the second pin 1423. When the second pin 1423 engages with the first limiting groove 11112, the upright 12 is fixedly and vertically positioned on the side of the support mechanism 111. The second elastic element 1424 is positioned between the rotating element 1421 and the second pin 1423. It provides a restoring force to the second pin 1423, causing the second pin 1423 to return to its initial position and engage with the first limiting groove 11112, thereby fixing the upright 12 vertically on the side of the support mechanism 111. Specifically, a plane bearing 14211 is provided through the rotating component 1421, which facilitates the rotation of the rotating component 1421 relative to the support mechanism 111. A push rod 1425 is also connected to the rotating component 1421, and the other end of the push rod 1425 is fixedly connected to the running assembly 11, which facilitates the user to unfold the treadmill. A guide groove 14221 is provided through the guide seat 1422, and the second pin 1423 moves through the guide groove 14221 and can engage with the first limiting groove 11112. The second elastic element 1424 is a spring. A limiting notch 14231 is provided on the side of the second pin 1423, which can make limiting contact with the limiting block 11113. Through the cooperation of the two, the rotation of the second unlocking mechanism 142 is limited. Specifically, one end of the pull rope 143 is fixedly connected to the rotating seat 1412, and the other end is fixedly connected to the second pin 1423.

[0039] Please see Figure 4 and Figure 9 As shown, in this embodiment, the two ends of the communication connection line 15 are electrically connected to the circuit board 112 and the control bracket assembly 13, respectively, and extend into the control bracket assembly 13 through the rotating part 1421, the column 12, the fixed seat 1411, and the rotating seat 1412 in sequence.

[0040] It should be noted that the specific working process of the treadmill 10 with one-button quick-folding function of this utility model is as follows: When the treadmill 10 needs to be quickly folded, the user presses the two unlocking pieces 1414 with both hands at the same time. The unlocking pieces 1414 overcome the elastic force of the first elastic member 1415, causing the first pin 1413 to disengage from the locking connection with the fixed seat 1411. At the same time, the first elastic member 1415 is compressed, so that the rotating seat 1412 can rotate relative to the fixed seat 1411, thereby realizing the control of the support assembly 13 relative to the fixed seat 1411. The two uprights 12 are folded; the rotating seat 1412 rotates relative to the fixed seat 1411, while driving the pull rope 143 to move upward. The pull rope 143 drives the second pin 1423 to move upward against the elastic force of the second elastic element 1424, so that the second pin 1423 disengages from the engagement connection with the first limiting groove 11112, thereby enabling the rotating element 1421 to rotate relative to the support mechanism 111, realizing the synchronous folding operation of the two uprights 12 relative to the running assembly 11, thus completing the rapid folding operation of the treadmill 10.

[0041] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0042] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
