The base is assembled into one piece by metal tubing. Secondly, as in the publicly disclosed patent document CN223208905U, a double-layer running board treadmill has a base that is basically the same as that in the publicly disclosed patent document CN216497260U. It is also assembled into one piece by metal tubing. The difference is that it has multiple connectors on the inner walls of the left and right side tubes of the base. The running board is placed on the connectors and then fixed to the connectors by fasteners. The running board is supported by multiple connectors.

[0004] The two common assembly methods mentioned above not only involve complicated assembly processes and high assembly costs, but also result in relatively heavy overall weight of the base tubes and common running boards, leading to higher transportation costs. Utility Model Content

[0038] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments: See Figures 1-22 A modular treadmill includes a main frame of the treadmill assembled from multiple modularly designed components. Specifically, the main frame of the treadmill includes a front support unit 1 and a running board unit 2. In this form, the front support unit 1 and the front end of the running board unit 2 cooperate with each other. The front roller 91 is installed on the front support unit 1, and the rear end of the running board unit 2 has an installation position 98 for installing the rear roller 92.

[0039] Specifically, the running board unit 2 includes a main body 21 serving as the running surface and pedals arranged on the left and right sides of the main body 21: a left pedal 22 and a right pedal 23. In one embodiment, the left pedal 22, the main body 21, and the right pedal 23 are assembled or integrally formed. For integral forming, an extruder can be used to form the running board unit 2 with one or more hollow internal parts. To improve the support strength of the running board unit 2, it can be further formed to include transverse and / or longitudinal and / or diagonally arranged ribs 24. See [reference needed] for details. Figure 21 , Figure 22 As shown.

[0040] For the rear end of the running board body 2, such as Figure 1 , Figure 7 As shown, the mounting positions are formed by extending from the rear end of the left pedal 22 and the rear end of the right pedal 23. One end of the rear roller 92 is mounted at the mounting position at the rear end of the left pedal 22, and the other end is mounted at the mounting position at the rear end of the right pedal 23. The center mounting shaft of the rear roller 92 can then be positioned by bolts.

[0041] In this embodiment, the front support unit 1 and the running board unit 2 that constitute the whole are relatively independent modules. As for constituting the whole, it can be understood that each unit is made into an integral module during the manufacturing process, such as module A (front support unit) and module B (running board unit). In the assembly process, module A and module B are assembled into one and fixed as the main support of the treadmill.

[0042] As one embodiment, the front support unit 1, which constitutes the whole, is composed of a front left support arm 11, a front right support arm 12, and a front connecting arm 13 that connects to the front left support arm 11 and the front right support arm 12 at both ends. The three are assembled into one piece or formed as one piece. After the front support unit 1 and the running board unit 2 are assembled, a closed loop is formed at the front support unit 1 to ensure the overall strength.

[0043] In another implementation, the front support unit 1 is a treadmill head shell, such as... Figure 15-17 As shown, the treadmill head shell is a single upper shell 14 or a single lower shell 15, or an upper shell 14 and a lower shell 15 assembled together. In this form, there is no metal tube base, and the whole is made of lighter plastic material, resulting in a lighter overall weight.

[0044] In this configuration, the front end of the running board unit 2 includes several first grooves 25, and the treadmill head shell includes mounting heads 16 that are inserted into the first grooves 25. After the mounting heads 16 are inserted into the first grooves 25, the two are fixed by fasteners or locked by a snap-fit ​​structure.

[0045] The mounting head 16 is preferably formed on the lower housing 15. The lower housing 15 is used to install the front roller 91. After assembling the lower housing 15 with the running plate unit 2, other components, including motors and controllers, can be installed, and then the upper housing 14 can be closed.

[0046] To further enhance the overall strength, a crossbar 93 (limiting member) can be installed on the front support unit 1 to provide reinforcement. The two ends of the crossbar 93 on the front support unit 1 are connected to the front left support arm 11 and the front right support arm 12.

[0047] The crossbar 93 can be positioned between the front roller 91 and the running plate unit 2. Alternatively, a receiving groove 94 adapted to the crossbar 93 can be opened on the front end face of the running plate unit 2.

[0048] In addition to its reinforcing function, the crossbar 93 also serves as a limit. When assembling the front support unit 1, the user only needs to push the front support unit 1 until the crossbar 93 contacts the running plate unit 2. At this point, the installation is complete, and then the front support unit 1 can be locked.

[0049] Of course, other types of limiting components that serve as limiting elements can also be set at the front end of the running board unit 2 to facilitate the installation of the front support unit 1.

[0050] However, after the crossbar 93 is installed on the front support unit 1, it isolates the front roller 91, affecting the normal installation of the running belt. Therefore, in this configuration, if... Figure 18-20 As shown, a notch 96 is provided at any part in front of the front roller 91 on the front support unit 1 for the running belt 95 to pass through. The front end of the ring-shaped running belt 95 passes through the notch 96 and enters the accommodating space formed by the front support unit 1 and the front roller 91. Since there is no other part blocking the rear roller 92, the running belt 95 can be directly fitted onto the rear roller 92.

[0051] Furthermore, a notch connector 97 is also fitted at the notch 96 so that after the running belt 95 is installed, the notch connector 97 can be installed at the notch 96 so that its two ends are connected to the two ends of the notch 96 respectively, thereby ensuring the strength at that point. Of course, the style of the notch connector 97 can be designed to fit the notch 96 and fill the notch 96 after installation.

[0052] The connection between the notch connector 97 and the corresponding part of the front bracket unit 1 can be achieved by fastener locking or other methods.

[0053] There are multiple ways to assemble the front support unit 1 and the running board unit 2. This embodiment lists the following four assembly methods: For the first type of coordination, such as Figure 1-4 As shown: The running board unit 2 is divided into a main body 21 located in the middle and a left pedal 22 and a right pedal 23 located on both sides. The front end of the left pedal 22 and the front end of the right pedal 23 each have a first groove 25. The first groove 25 can be formed simultaneously during the extrusion molding of the running board unit 2, and the inlet and outlet of the first groove 25 are formed on the front end face of the left pedal 22 and the front end face of the right pedal 23.

[0054] The front left support arm 11 and the front right support arm 12 of the front support unit 1 correspond to the first groove 25 of the left pedal 22 and the first groove 25 of the right pedal 23, respectively. During assembly, the front left support arm 11 and the front right support arm 12 are inserted into the corresponding first groove 25. As one embodiment, the shape and size of the front left support arm 11 are adapted to the shape and size of the first groove 25 on the left pedal 22, and the shape and size of the front right support arm 12 are adapted to the shape and size of the first groove 25 on the right pedal 23.

[0055] After the front support unit 1 and the running board unit 2 are assembled, they need to be fixed. There are several ways to fix them. For example, several through holes 27 that communicate with the first groove 25 are opened at the front end of the left pedal 22 and the right pedal 23. Correspondingly, corresponding bolt holes 17 are also opened on the front left support arm 11 and the front right support arm 12. Fasteners are passed through the through holes 27 and locked with the bolt holes 17, thereby fixing the front support unit 1 to the front end of the running board unit 2.

[0056] The number and location of the through holes 27 and bolt holes 17 can be selected according to actual needs, such as... Figure 1 and Figure 2 The method shown is one of the options.

[0057] For the reverse design of the first type of fit, such as Figure 5-6 As shown: It is the opposite of the first type of connection mentioned above. The first type of connection involves inserting the support arm of the front support unit 1 into the running board unit 2, while the reverse design of the first type of connection involves inserting the front end of the running board unit 2 into the front support unit 1.

[0058] Specifically, corresponding slots 18 are provided on the front left support arm 11 and the front right support arm 12 of the front support unit 1. The front end of the left pedal 22 and the front end of the right pedal 23 are respectively provided with protrusions 28 inserted into the corresponding slots 18. As one option, the protrusions 28 are specifically provided on the front end surface of the left pedal 22 and the front end surface of the right pedal 23.

[0059] In other words, the specific structural form of the reverse design of the first type of fit can refer to the first type of fit, such as the fit of shape and size, the selection of fixing method, etc.

[0060] For the second type of coordination, such as Figure 7-9 As shown: The front left support arm 11 and the front right support arm 12 of the front support unit 1 are respectively provided with fixing plates 4. As one option, the fixing plates 4 are L-shaped. One side of the fixing plate 4 on the front left support arm 11 is fixed to the inner side wall of the front left support arm 11, and one side of the fixing plate 4 on the front right support arm 12 is fixed to the front right support arm 12. The fixing method can be welding, fastener fixing or integral molding, etc. The other side of the L-shaped fixing plate 4 is provided with a first hole 41.

[0061] The running board unit 2 is divided into a main body 21 located in the middle and a left pedal 22 and a right pedal 23 located on both sides. The front end face of the left pedal 22 and the front end face of the right pedal 23 are respectively provided with a second hole 42 corresponding to the first hole 41. When the front left support arm 11 is aligned with the front end face of the left pedal 22 or inserted into the first groove 25 of the front end face of the left pedal 22, and when the front right support arm 12 is aligned with the front end face of the right pedal 23 or inserted into the first groove 25 of the front end face of the right pedal 23, the first hole 41 and the second hole 42 are aligned. Then, the fastener is passed through the first hole 41 and then connected with the second hole 42 to fix the front support unit 1 on the running board unit 2. If the second hole 42 is a threaded hole, it is threaded to engage with the fastener.

[0062] For the third type of coordination, such as Figure 11-15 As shown: Similar to the second type of fit, the third type of fit also has fixing plates 4 on the front left arm 11 and the front right arm 12 of the front support unit 1. The difference is that in the second type of fit, the fixing plates 4 are arranged on the inner side wall of the front left arm 11 and the front right arm 12, while in the third type of fit, the fixing plates 4 are arranged on the upper side wall, lower side wall and outer side wall of the front left arm 11 and the front right arm 12.

[0063] Adaptably, the shape of the fixing piece 4 in this form is also somewhat different, specifically based on the height difference between the corresponding side wall of the front left support arm 11 and the corresponding side wall of the left pedal 22, and based on the height difference between the corresponding side wall of the front right support arm 12 and the corresponding side wall of the right pedal 23.

[0064] In this type of assembly, the fixing piece 4 also has two parts. One part is fixed on the front left support arm 11 or the front right support arm 12. The fixing method can be welding, fastener fixing or integral molding, etc. The other part is fixed on the left pedal 22 or the right pedal 23 and has a first hole 41.

[0065] The two parts of the fixing piece 4 are connected by a bending transition section, as detailed in the reference. Figures 12-14 As shown in the diagram, one option is to manufacture the fixing piece 4 by means of stamping or forming.

[0066] The running board unit 2 is divided into a main body 21 located in the middle and left pedals 22 and right pedals 23 located on both sides. The left pedals 22 and right pedals 23 are each provided with a second hole 42 corresponding to the first hole 41. The specific location of the second hole 42 depends on the installation position of the fixing piece 4 on the front left support arm 11 and the front right support arm 12. Figure 12 As shown, the fixing piece 4 is installed on the upper side wall of the front left support arm 11 and the front right support arm 12, and the second hole 42 is opened on the upper side wall of the left pedal 22 and the right pedal 23; Figure 13 As shown, the fixing piece 4 is installed on the outer side wall of the front left support arm 11 and the front right support arm 12, and the second hole 42 is opened on the outer side wall of the left pedal 22 and the right pedal 23; Figure 14 As shown, the fixing piece 4 is installed on the lower side wall of the front left support arm 11 and the front right support arm 12, and the second hole 42 is opened on the lower side wall of the left pedal 22 and the right pedal 23.

[0067] When the front left support arm 11 is aligned with the front end face of the left pedal 22 or inserted into the first groove 25 of the front end face of the left pedal 22, and when the front right support arm 12 is aligned with the front end face of the right pedal 23 or inserted into the first groove 25 of the front end face of the right pedal 23, the first hole 41 and the second hole 42 are aligned. Then, the fastener is passed through the first hole 41 and connected with the second hole 42 to fix the front support unit 1 on the running plate unit 2. If the second hole 42 is a threaded hole, it is threaded to engage with the fastener.

[0068] For other assembly methods, such as the front support unit 1 being glued to the running board unit 2, as shown in the figure, after assembling the front support unit 1 and the running board unit 2 (such as plug-in assembly) and installing the running belt 95, the front roller 91 and the rear roller 92 are fixed in position. The tension of the running belt 95 can tighten the front support unit 1 and prevent it from detaching from the running board unit 2.

[0069] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
