Description

Technical Field

[0001] This utility model relates to a stationary bicycle, and more particularly to a stationary bicycle with a power generation function. Background Technology

[0002] A stationary bike is an indoor stationary fitness device that simulates outdoor cycling. Its main difference from a regular home exercise bike lies in its flywheel structure and resistance adjustment method, which can better simulate the real road feel and allow riders to perform various movements such as standing riding, climbing, and sprinting.

[0003] In order to improve the environmental friendliness of existing exercise bikes, a built-in generator is installed in the exercise bike. The mechanical energy generated by the user's pedaling can directly power the bike's electronic dashboard, sensors, Bluetooth module, etc. This means that the bike does not need to be plugged into a power outlet or have its batteries replaced, achieving "self-sufficiency". This greatly reflects the concept of environmental protection and sustainable development.

[0004] In most exercise bikes with generators, the generator is usually driven by a belt drive system. However, the drive belt can become loose over time, which compromises the reliability of the belt drive system. Furthermore, if the drive belt becomes loose, it will reduce the generator's efficiency and thus its power output. Utility Model Content

[0005] The technical problem to be solved by this utility model is to provide a dynamic bicycle with power generation function, which can avoid the problem of the transmission belt in the belt drive assembly becoming loose during operation.

[0006] The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows: a stationary bicycle with power generation function, including a stationary bicycle body, a generator assembly installed on the stationary bicycle body, and a belt drive assembly that drives the generator assembly. The stationary bicycle body is also provided with a belt tensioning mechanism, which is used to tighten the drive belt in the belt drive assembly. The belt tensioning mechanism includes a mounting plate installed on the stationary bicycle body; a telescopic device installed on the inner side wall of the mounting plate, with the telescopic end of the telescopic device facing the drive belt in the belt drive assembly; and a roller assembly installed on the telescopic end of the telescopic device, which is used to control the roller assembly to tighten the drive belt.

[0007] A further preferred embodiment of this utility model is as follows: the mounting plate is arranged in an n-shape, the mounting plate is inserted into the main body of the exercise bike, and at least two first screw holes are opened on the outer side wall of the mounting plate, each of the first screw holes is provided with a first bolt, and the mounting plate is detachably connected to the exercise bike through the first bolts.

[0008] A further preferred embodiment of this utility model is as follows: a connecting block is provided on the side walls of the left and right sides of the telescopic device, and each connecting block has at least two through holes. A second bolt is provided in each through hole. The side wall of the inner side of the mounting plate has the same number of second screw holes as the through holes. The second bolt passes through the through holes and is screwed into the second screw holes.

[0009] A further preferred embodiment of the present invention is as follows: the roller assembly includes a mounting frame connected to the telescopic end of the telescopic device, a roller for pressing the transmission belt is rotatably disposed in the mounting frame, and a limiting block is respectively disposed at the left and right ends of the bottom of the mounting frame, and the roller is located between the two limiting blocks when pressing the transmission belt.

[0010] A further preferred embodiment of this utility model is: each of the limiting blocks has an installation groove on its inner wall, and a guide roller is vertically and rotatably arranged in each of the installation grooves.

[0011] Compared with the prior art, the advantage of this utility model is that by setting a belt tensioning mechanism on the main body of the exercise bike, the belt tensioning mechanism can be used to tighten the transmission belt in the belt drive assembly. This can prevent the transmission belt from becoming loose when driving the generator assembly, thus ensuring the working efficiency of the generator assembly and thus ensuring the power generation of the generator.

[0015] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings. Those skilled in the art will appreciate that these descriptions are merely descriptive and exemplary and should not be construed as limiting the scope of protection of the present invention.

[0016] It should be noted that similar labels in the following figures indicate similar items; therefore, once an item is defined in one figure, it may not be further defined and explained in subsequent figures.

[0017] This embodiment mainly describes the structure of a stationary bicycle with power generation function, as follows: like Figures 1-6 As shown, a stationary bicycle with power generation function includes a stationary bicycle body 1, a generator assembly 2 installed on the stationary bicycle body 1, and a belt drive assembly 3 that drives the generator assembly 2. A belt tensioning mechanism 4 is also provided on the stationary bicycle body 1. The belt tensioning mechanism 4 is used to tighten the drive belt in the belt drive assembly 3. In this way, the belt tensioning mechanism 4 can prevent the drive belt from becoming loose when driving the generator assembly 2, thus ensuring the working efficiency of the generator assembly 2 and thus ensuring the power generation of the generator. The belt tensioning mechanism 4 includes a mounting plate 41 installed on the main body 1 of the exercise bike. A telescopic device 42 (such as an electric telescopic rod or a hydraulic telescopic device) is provided on the inner side wall of the mounting plate 41. The telescopic end of the telescopic device 42 faces the transmission belt in the belt drive assembly 3. A roller assembly 43 is provided at the telescopic end of the telescopic device 42. When the telescopic device 42 extends, it can control the roller assembly 43 to press the transmission belt. When the transmission belt is working, it can drive the roller assembly 43 to rotate. This can reduce the wear on the transmission belt when pressing it, thereby ensuring the service life of the transmission belt. The setting of the telescopic device 42 can control the pressing effect of the roller assembly 43 on the transmission belt according to the different slack of the transmission belt, thus improving the practicality of the belt tensioning mechanism 4.

[0018] Furthermore, to facilitate the installation of the belt tensioning mechanism 4 onto the main body of the exercise bike, the mounting plate 41 is arranged in an n-shape. This allows the mounting plate 41 to be inserted into the main body 1 of the exercise bike. To ensure the stability of the mounting plate 41 when installed on the main body 1, at least two first screw holes 411 are provided on the outer side wall of the mounting plate 41. A first bolt 47 is provided in each of the first screw holes 411. When the first bolt 47 is tightened, it passes through the first screw hole 411 and presses against the main body 1 of the exercise bike, thus ensuring the stability of the mounting plate 41 when installed on the main body 1. Since the connection between the mounting plate 41 and the main body 1 is achieved through the cooperation of the first bolt 47 and the first screw hole 411, removing the first bolt 47 from the first screw hole 411 allows the mounting plate 41 to be removed from the main body 1, facilitating the disassembly of the belt tensioning mechanism 4.

[0019] Furthermore, to facilitate the assembly and disassembly of the telescopic device 42, a connecting block 45 is provided on the side walls of the left and right sides of the telescopic device 42, and each connecting block 45 has at least two through holes 451, with a second bolt 46 installed in each through hole 451. At the same time, the same number of second screw holes 412 as the through holes 451 are provided on the inner side wall of the mounting plate 41. The second bolts 46 can be screwed into the second screw holes 412 after passing through the through holes 451. Thus, when disassembling the telescopic device 42, it is only necessary to unscrew the second bolts 46 from the second screw holes 412. When installing the telescopic device 42, first align the through holes 451 on the connecting block 45 with the second screw holes 412 on the mounting plate 41, then insert the second bolts 46 into the through holes 451, and screw the second bolts 46 through the through holes 451 into the second screw holes 412. This facilitates the assembly and disassembly of the telescopic device 42.

[0020] Furthermore, the roller assembly 43 includes a mounting bracket 431 connected to the telescopic end of the telescopic device 42, and a roller 432 for pressing the transmission belt is rotatably disposed in the mounting bracket 431. At the same time, a limiting block 44 is respectively provided at the left and right ends of the bottom of the mounting bracket 431. Thus, when the roller 432 presses the transmission belt, it is located between the two limiting blocks 44, which can prevent the transmission belt from detaching from the roller 432, thereby improving the reliability of the belt tensioning mechanism 4.

[0021] Furthermore, in order to reduce the wear of the transmission belt when it passes between the two limit blocks 44, a mounting groove 441 is provided on the inner wall of each limit block 44. At the same time, a guide roller 442 is vertically and rotatably installed in each mounting groove 441. In this way, when the transmission belt passes between the two limit blocks 44, it can drive the guide roller 442 to rotate, thereby reducing the wear of the transmission belt when it passes between the two limit blocks 44.
