Description

Technical Field

[0001] The present invention relates to the technical field of fitness equipment, and in particular to a treadmill. Background Art

[0002] Running has become a project suitable for all people. When the outdoor weather is bad and one doesn't want to interrupt the fitness plan, the treadmill has become a popular way of running and fitness. The treadmill is an essential fitness equipment in many gyms and also a necessary magic weapon for running and fitness in many families.

[0003] Existing treadmills generally have a flat exercise mode and a climbing exercise mode. For the climbing exercise mode, it is generally achieved by a lifting structure that raises the front end of the treadmill. For the lifting structure, as in the existing publicly disclosed patent documents CN218248322U and CN219941696U, it includes a rotatable support foot. When the support foot is retracted or folded, it is used for the flat exercise mode, and when the support foot is unfolded, the front end of the treadmill is lifted and the running platform is inclined for the climbing exercise mode.

[0004] Taking the picture in the existing publicly disclosed patent document CN307898688S as an example, the front end of the treadmill generally has an outer housing, which is used to accommodate various components including the drive structure and components. This outer housing is usually higher than the running platform of the treadmill.

[0005] In the climbing mode, the user's running intensity is higher. Correspondingly, the user's position on the running platform of the treadmill is extremely likely to be more forward. Due to the existence of the outer housing with a relatively high height at the front end of the treadmill, in the climbing mode, the user is extremely likely to kick the outer housing, which not only easily damages the outer housing, but also easily affects the user's running rhythm. In severe cases, it will cause the user to trip when retracting the leg, posing a safety hazard. The lifting structure with a rotatable support foot cannot solve the above technical problems, so the applicant makes improvements. Summary of the Invention

[0006] The present invention provides a treadmill in view of the deficiencies in the prior art.

[0007] To solve the above technical problems, the present invention is solved by the following technical solutions: A treadmill, comprising A main frame of the treadmill, with a driving roller rotatably configured at its front end and a driven roller rotatably configured at its rear end, and a running belt is sleeved on the driving roller and the driven roller; A head frame of the treadmill, which is rotatably connected to the front end of the main frame of the treadmill, has a first position for keeping the running platform of the treadmill in a horizontal state and a second position for keeping the running platform of the treadmill in an inclined state, and a driving unit fixedly installed on the head frame of the treadmill and drivingly connected to the driving roller; and A positioning unit, which is configured on the head frame of the treadmill and / or the main frame of the treadmill, for positioning the head frame of the treadmill; A treadmill head shell is assembled on the head frame of the treadmill.

[0008] In the above technical solution, preferably, the driving unit is a motor, and the driving unit is drivingly connected to the driving roller through a belt or a chain.

[0009] In the above technical solution, preferably, a plurality of support wheels are arranged at the front end of the head frame of the treadmill.

[0010] In the above technical solution, preferably, the rotation connection point of the driving roller and the head frame of the treadmill is concentric.

[0011] In the above technical solution, preferably, the distance range between the rotation center line of the driving roller and the rotation center line of the head frame of the treadmill is 0 - 25 mm.

[0012] In the above technical solution, preferably, the front end of the main frame of the treadmill includes a threaded hole, a bolt is threadedly connected to the threaded hole, a bushing is arranged on the bolt, and the head frame of the treadmill is rotatably connected to the bushing.

[0013] In the above technical solution, preferably, a first hole is formed in the head frame of the treadmill, and a positioning pin is arranged at the first hole; A plurality of second holes matching the positioning pin are formed in the main frame of the treadmill, and the arrangement position of the second holes corresponds to the movement path of the first hole; When the inner end of the positioning pin is inserted into the corresponding second hole, the head frame of the treadmill is positioned.

[0014] In the above technical solution, preferably, a first positioning shaft and a second positioning shaft for limiting the rotation range of the head frame of the treadmill are fixed at the front end of the main frame of the treadmill.

[0015] In the above technical solution, preferably, the head frame of the treadmill includes a front rod and two support rods arranged at both ends of the front rod, and the two support rods are respectively rotatably connected to both sides of the front end of the main frame of the treadmill.

[0016] In the above technical solution, preferably, the end of the support rod facing the main frame of the treadmill is arc-shaped; When the head frame of the treadmill is in the first position, the first positioning shaft is located above the support rod, and the second positioning shaft abuts against the arc-shaped end of the support rod or is located on the side of the arc-shaped end of the support rod.

[0017] The beneficial effects of the present invention are: The front part of the treadmill of the present invention can be flipped as a whole. When it is flipped, it can drive the front housing of the treadmill to flip synchronously, so that the front housing of the treadmill can avoid the front and rear movement range of the user's feet when running, preventing the user from kicking the front housing of the treadmill when running. And because the user will not kick the front housing of the treadmill, the movable range of the user on the running belt becomes larger; Compared with the flip-up support feet, the flip-up length of this application is longer, so that the front end of the treadmill can be lifted higher, and the adjustable slope range of the treadmill is larger; After the front part of the treadmill is flipped down as a whole, it forms a "panoramic running belt" effect in terms of visual effect, making the whole more beautiful.

[0024] The present invention will be further described in detail below in conjunction with the drawings and specific embodiments: Refer to Figures 1-6 , a treadmill, including a treadmill main frame 1 and a treadmill head frame 2 rotatably connected to the treadmill main frame 1. That is, in this application, the existing common treadmill frame is divided into two parts: the treadmill main frame 1 and the treadmill head frame 2. The treadmill head frame 2 is used as a lifting structure, and the front end of the treadmill is lifted by flipping the treadmill head frame 2, so that the running belt of the treadmill is inclined for uphill exercise.

[0025] In this embodiment, a driving roller 11 is rotatably arranged at the front end of the treadmill main frame 1, and a driven roller is rotatably arranged at the rear end. The running belt 12 is sleeved on the driving roller 11 and the driven roller. This design is the same as the existing design. In fact, the arrangement positions of the driving roller, the driven roller and the running belt in the existing treadmill are the same as or similar to those in this application. After the design improvement of this application, for users, the running-related effects will not be reduced at all.

[0026] The power of the driving roller 11 is provided by the driving unit 3 fixed to the head frame 2 of the treadmill. The driving unit 3 moves synchronously with the flipping of the head frame 2 of the treadmill. For the transmission mode between the driving unit 3 and the driving roller 11, it can be achieved by means of a belt 31 or a chain. As an option, the driving unit 3 can be a motor.

[0027] When the head frame 2 of the treadmill flips, the driving unit 3 flips accordingly, while the driving roller 11 needs to rotate continuously to provide the power required for the running belt to move. Therefore, preferably, the rotation connection points of the driving roller 11 and the head frame 2 of the treadmill are concentrically designed. Thus, no matter how the driving unit 3 flips, the power required by the driving roller 11 can always be stably provided.

[0028] Since the belt or the chain has a certain tension and a certain controllable elongation range, especially for the belt, as an option, the rotation connection points of the driving roller 11 and the head frame 1 of the treadmill can be non - concentric, but the deviation should not be too large. In this embodiment, the distance range between the rotation center line of the driving roller 11 and the rotation center line of the head frame 2 of the treadmill is between 0 - 25 mm.

[0029] In addition to installing the driving unit 3, the front part of the treadmill can also be used to install other components, such as a display screen, a speaker, a controller, various circuits, etc. The installation positions and installation methods of various components are not considered in this application and can refer to the existing design. The same as the existing design, a treadmill head shell 7 is also installed on the head frame 2 of the treadmill. The treadmill head shell 7 also flips with the flipping of the head frame 2 of the treadmill. In the climbing mode, after the treadmill head shell 7 flips, it provides more sufficient movable space for the user, and the user will not be affected by the treadmill head shell when running to the front end position of the running belt 12, which is something that the existing treadmill cannot achieve.

[0030] The treadmill head shell 7 includes an upper shell 71 and a lower shell 72 that are assembled and cooperated with each other. Components such as the head frame 2 of the treadmill and the driving unit 3 are included within the treadmill head shell 7.

[0031] The state after the head frame 2 of the treadmill flips is as Figure 4 shown. For the treadmill head shell 7, it only needs not to be interfered by other parts of the treadmill when flipping with the head frame 2 of the treadmill. As an option, one end of the treadmill head shell 7 close to the main frame 1 of the treadmill is arc - shaped, and for the convenience of understanding, it is named the arc - shaped end 73, so that it will not be interfered by other parts of the treadmill when rotating with the head frame 2 of the treadmill.

[0032] As an option, an arc-shaped baffle 74 is fixed on the main frame 1 of the treadmill, which is matched with the arc-shaped end 73 of the head shell 7 of the treadmill, so that when the treadmill is in a horizontal state, the integrity and coordination of the treadmill are better.

[0033] As an option, one end of the upper shell 71 close to the main frame 1 of the treadmill has a stop bar 75, and the stop bar 75 is perpendicular or tends to be perpendicular to its top wall, and is used to block the components located in the head shell 7 of the treadmill after the head frame 2 of the treadmill is flipped, such as Figure 6 As shown, after the stop bar 75 is provided, from the perspective of the user's line of sight during exercise, the components inside the head shell of the treadmill cannot be seen.

[0034] As is well known, when a user runs, there should be no obstructive components within the range of the front and rear movements of their feet. The front shell of the existing treadmill restricts the user to only move within a certain range of the running belt. After the design improvement of this application, with the same size of the running belt, it can provide a more sufficient range of movement for the user, which is equivalent to lengthening the length of the running belt, and this is the additional effect achieved at the same cost.

[0035] Compared with the flip-up support feet, the flip of the head frame of the treadmill greatly increases the length of the "rotating arm". The longer the length of the "rotating arm", the higher the height that can be lifted, and the more slope modes can be selected by the user, and the support effect remains after lifting.

[0036] As can be seen from the attached drawings of the specification of this application, after the front part of the treadmill is turned down as a whole, from the perspective of a user standing on the treadmill, the front part of the treadmill is hidden under the running platform of the treadmill, which forms a "panoramic running platform" effect in terms of visual effect, bringing a visual effect similar to that of a full-screen mobile phone and a panoramic sunroof, and the overall appearance is more beautiful, such as Figure 6 shown.

[0037] For the convenience of supporting the head frame 2 of the treadmill, in this embodiment, a number of support wheels 21 are arranged at the front end of the head frame 2 of the treadmill. As an option, a support wheel 21 can be installed on each side of the front end of the head frame 2 of the treadmill.

[0038] In this embodiment, the head frame 2 of the treadmill includes a front rod 22 and two support rods 23 arranged at both ends of the front rod 22. The two support rods 23 are respectively rotatably connected to both sides of the front end of the main frame 1 of the treadmill. The front rod 22 and the two support rods 23 can be integrally formed, welded or fixedly connected into one body through fasteners. The support wheel 21 and the drive unit 3 can be fixedly installed on the front rod 22. Among them, the support wheel 21 is installed at the bottom of the front rod 22, and the drive unit 3 is installed on the inner side wall of the front rod 22. The space between the inner side wall of the front rod 22 and the running belt 12 can also be used to accommodate other components.

[0039] such asFigure 3 As shown, the front end of the treadmill main frame 1 includes a threaded hole 41. A bolt 42 is threadedly connected to the threaded hole 41. A bushing 43 is sleeved on the bolt 42. The support rod 23 is rotatably connected to the bushing 43 to form a rotational fit between the treadmill head frame 2 and the treadmill main frame 1.

[0040] To make the overall structure more compact, the front end of the treadmill main frame 1 can be a metal plate. As an option, a component 44 with internal threads is fixed on the outer wall of the front end of the treadmill main frame 1. The threaded hole 41 is opened on this component. The bolt 42 is threadedly connected to the component 44. The design of this component meets the installation requirements of the driving roller 11 and the treadmill head frame 2 when they are concentrically designed. At the same time, it can also be used as a gasket function, enabling a certain gap to be left between the support rod 23 and the treadmill main frame 1 to avoid frictional damage between the two during flipping.

[0041] After the treadmill head frame 2 is flipped to a suitable position, it needs to be positioned to keep the treadmill stable at the required angle. In this embodiment, a first hole 51 is opened on the treadmill head frame 2. A positioning pin 52 is arranged at the first hole 51. A number of second holes 53 that cooperate with the positioning pin 52 are opened on the treadmill main frame 1. When the treadmill head frame 2 needs to be flipped, the inner end of the positioning pin 52 is separated from the second hole 53; when the treadmill head frame 2 needs to be positioned, the inner end of the positioning pin 52 is inserted into the corresponding second hole 53.

[0042] For the first hole 51 and the positioning pin 52, the two can be movably connected or in a threaded fit form. In the form of movable connection, the positioning pin 52 is operated in a push-pull manner; in the form of threaded fit, the positioning pin 52 is operated by rotation.

[0043] Since the treadmill slope is determined by the flipping angle of the treadmill head frame 2, and when the user needs to position the treadmill head frame 2 at the required angle, corresponding second holes 53 are required to cooperate with the positioning pin 52. Therefore, the position setting of the multiple second holes 53 has certain requirements. In this embodiment, the setting position of the second hole 53 corresponds to the movement path of the first hole 51, that is, the first hole 51 makes an arc movement as the treadmill head frame 2 flips. It takes the rotation connection point of the support rod 23 as the center of the circle. The second holes 53 are arranged within the orthographic projection range of the movement path of the first hole 51 so that when the treadmill head frame 2 flips to a suitable position, there is a corresponding second hole 53 for the positioning pin to be inserted.

[0044] The number of the second holes 53 can be set according to actual needs. For example, if three are set, the treadmill head frame 2 correspondingly has three positions that can be locked, providing three modes with different intensities.

[0045] The cooperation of the positioning pin 52, the first hole 51, and the second hole 53 forms a positioning unit required for positioning the treadmill head frame 2.

[0046] In this embodiment, a first positioning shaft 61 and a second positioning shaft 62 for limiting the rotation range of the treadmill head frame 2 are fixed at the front end of the treadmill main frame 1. Among them, the first positioning shaft 61 is used to limit the upward turning range of the treadmill head frame 2, and the second positioning shaft 62 is used to limit the downward turning range of the treadmill head frame 2, so that users can quickly and accurately know that the treadmill head frame has been turned to the maximum range.

[0047] As an option, the end of the support rod 23 facing the treadmill main frame 1 is arc-shaped to prevent interference between the support rod 23 and the second positioning shaft 62 when the support rod 23 rotates.

[0048] When the treadmill running platform is in a horizontal state, the treadmill head frame 2 is in the first position. At this time, the first positioning shaft 61 is located above the support rod 23, and the second positioning shaft 62 abuts against the arc-shaped end of the support rod 23 or is located on the side of the arc-shaped end of the support rod 23; when the treadmill running platform is in an inclined state, the treadmill head frame 2 is in the second position, that is, all inclined states of the treadmill running platform are considered as the second position of the treadmill head frame.

[0049] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
