Description

Technical Field

[0001] This utility model belongs to the field of treadmill technology, and in particular relates to a lightweight treadmill. Background Technology

[0002] Currently, the treadmill frame and drive unit are all installed in a single housing, requiring the entire treadmill to be repaired in case of a malfunction. Similarly, upgrading the drive unit necessitates disassembling the entire treadmill. This leads to difficulties in maintenance and restricts the ability to easily upgrade the hardware system.

[0003] Therefore, some modular treadmills have emerged on the market to address the aforementioned issues. For example, Chinese invention patent CN119303271A, entitled "A Modular Treadmill," discloses a modular treadmill. It includes a frame and a drive unit. The frame comprises a frame, a first roller, a second roller, and a running belt; the running belt forms a closed loop around the first and second rollers. The drive unit includes an electronic control module, a drive assembly, a transmission assembly, and a support. When the drive assembly is actuated, the transmission assembly can be driven to rotate. The first roller is provided with a component to be driven that matches the transmission assembly. When the component to be driven is driven by the transmission assembly, the second roller is driven to rotate around a rotation axis in the lateral direction, causing the running belt to circulate around the first and second rollers. A first connecting assembly and a second connecting assembly connect the transmission assembly and the component to be driven.

[0004] However, in the aforementioned patented products, the electronic control module, drive components, and transmission components are mainly fixedly installed by brackets to form a drive device. The method of installing the drive device on one side of the frame and first installing each component by brackets is difficult in the installation process, and the stability of these components after installation is poor. In addition, the assembled treadmill body is too bulky. Utility Model Content

[0005] The purpose of this utility model is to provide a lightweight treadmill to solve the technical problems of existing modular treadmills, such as the difficulty in installing components, the poor stability of the connection between the assembled components and the support frame, and the overall bulkiness of the assembled treadmill.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a lightweight treadmill, including a main frame unit and a head frame unit equipped with a drive module, wherein a connecting unit is provided on the head frame unit, the connecting unit is a metal part, and a limiting position matching the connecting unit is provided on the main frame unit, wherein the main frame unit and the head frame unit are connected into one unit through the cooperation of the connecting unit and the limiting position.

[0023] like Figure 1-8As shown: A lightweight treadmill includes a main frame unit 1 and a head frame unit 2 equipped with a drive module. The head frame unit 2 is provided with a connecting unit 3, which is a metal part to increase the stability of the connection between the head frame unit 2 and the main frame unit 1. The connecting unit 3 can be made of steel, aluminum, iron or other single metals or alloys. The main frame unit 1 is provided with a limiting point that matches the connecting unit 3. In this embodiment, the limiting point is located on both sides of the main frame unit 1 and corresponds to the connecting unit 3 to fix the connecting unit 3. The main frame unit 1 and the head frame unit 2 are connected into one unit through the cooperation of the connecting unit 3 and the limiting point. As one option, it can be configured as a detachable connection. The head frame unit 2 is used to drive the module, and the detachable connection makes it easy to replace the drive module and achieve quick disassembly and assembly, which is convenient for maintenance and replacement.

[0024] The head frame unit 2 is made of non-metallic materials. In this embodiment, the head frame unit 2 is made of plastic or other lightweight non-metallic materials, which can effectively reduce the weight of the head frame unit 2, thereby reducing the overall weight of the treadmill and making the treadmill less bulky. At the same time, it is easier to assemble the head frame unit 2. The head frame unit 2 has an internal cavity for accommodating the drive module. By setting the internal cavity, the drive module can be fixed inside by the preset storage of each component, so that the various components inside can be effectively placed and not scattered.

[0025] like Figure 6-8 As shown: The connecting unit 3 includes plug-in parts 301 fixedly installed on both sides of the head frame unit 2 and a middle stop bar 302 connected between the plug-in parts 301 on both sides. The two ends of the middle stop bar 302 and the plug-in parts 301 on both sides are integrally formed by welding to increase the connection strength. When the connecting unit 3 is plugged into the main frame unit 1, the middle stop bar 302 can abut against one side of the main frame unit 1 to control the insertion depth of the connecting unit 3 and play a limiting role.

[0026] like Figure 6-8 As shown: The head frame unit 2 has mounting positions 201 on both sides for fixing the connector 301. The mounting positions 201 protrude from the bottom surface of the head frame unit 2, so that when the connector 301 is installed on it, its upper surface can be flush with the upper surface of the head frame unit 2 to facilitate the assembly of the head frame unit 2. The connector 301 is fixedly installed in the mounting position 201 by screw connection. When assembling the connector 301, first set the connector 301 on the mounting position 201, so that the threaded hole on its bottom surface corresponds to the through hole on the mounting position 201. Then, bolts are inserted under the head frame unit 2, so that they extend through the through hole into the threaded hole and are fixed. Generally, the bottom of the connector 301 has at least two sets of threaded holes for bolt tightening.

[0027] like Figure 3-6 As shown: One end of the connector 301 extends towards the main frame unit 1 to the outside of the head frame unit 2. The length that the connector 301 can extend is related to the depth of the limiting slot 100. Extending it out is beneficial for faster connection of the main frame unit 1 and the head frame unit 2.

[0028] like Figure 5-6 As shown: The limiting points are limiting slots 100 opened on both sides of the main frame unit 1. The shape of the limiting slots 100 matches the plug-in parts 301. The head frame unit 2 is installed on one side of the main frame unit 1 through the plug-in parts 301 and the limiting slots 100. During assembly, the head frame unit 2 is first inserted into the corresponding limiting slots 100 through the plug-in parts 301 on both sides. The plug-in parts 301 are square tubes, and the corresponding limiting slots 100 are directional slots. Then, the head frame unit 2 is pushed to make the plug-in parts 301 extend into the limiting slots 100 until the middle stop bar 302 abuts against one side of the main frame unit 1 to limit the plug-in parts 301. At this time, the plug-in parts 301 are installed in place. Afterwards, the corresponding connecting holes on the sides of the main frame unit 1 and the plug-in parts 301 can be used to complete the bolt positioning to increase the connection strength between the two.

[0029] like Figure 6-8 As shown: The bottom of the head frame unit 2 is integrally formed with a support leg 202. The support leg 202 protrudes from the bottom surface of the head frame unit 2. The support leg 202 is provided to better support the treadmill. The support legs 202 are respectively arranged on both sides of the head frame unit 2. At the same time, an anti-slip pad is provided under the support leg 202.

[0030] like Figure 1-3 As shown: The drive module includes a drive motor 4 and a front roller 5 that is connected to the drive motor 4 in a transmission. The drive motor 4 is fixedly installed in the inner cavity of the head frame unit 2. The front roller 5 is rotatably installed in the head frame unit 2. The front roller 5 is provided with a pulley, which is connected to the transmission end installed on the drive end of the drive motor 4 through a synchronous belt.

[0031] like Figure 4 or Figure 8 As shown: The output shaft of the drive motor 4 is connected to a bearing housing 401, and a bearing is fitted inside the bearing housing 401. The bearing housing 401 is set to facilitate the drive of the drive motor 4. A fixing groove 303 for accommodating the bearing housing 401 is opened on one side of the connector 301. A limiting bolt 304 for fixing the bearing housing 401 is provided above the fixing groove 303. A frame is formed on the top of the fixing groove 303. The limiting bolt 304 is mounted on the frame and can move up and down. By rotating the limiting bolt 304, the bearing housing 401 can be tightened or loosened to achieve the fixed and limited position of the bearing housing 401.

[0032] like Figure 1-3 As shown: The main frame unit 1 includes a running platform 101 and a rear roller unit 102 installed on one side of the running platform 101. The running platform 101 is an integrally molded structure with a grid-like interior to increase strength. The two sides of the running platform 101 are support parts, and the limiting slots 100 are opened on the support parts. A running belt 103 is tensioned between the front roller 5 and the rear roller unit 102, and the running belt 103 forms an annular belt arranged along the running platform 101 around the front roller 5 and the rear roller unit 102. The rear roller unit 102 includes a rear roller and mounting seats arranged on both sides of the rear roller. The rear roller is detachably installed on the end of the running platform 101 away from the head frame unit 2 through the mounting seats, and is fixed and limited by bolt assembly to realize the multi-modality of the treadmill.

[0033] In summary, by setting up a head frame unit 2 with an inner cavity, the technical problems of existing modular treadmills, such as the difficulty in installing the drive module and the poor stability of the connection between the assembled components and the support, are solved. At the same time, the head frame unit 2, made of non-metallic parts, reduces the weight of the treadmill, and the connection unit 3, made of metallic parts, improves the stability of the connection, thereby solving the technical problem of the large overall weight of existing modular treadmills, which makes them too bulky.
