Description

Technical Field

[0001] The utility model relates to the technical field of resistance regulators, in particular to a vehicle-mounted optocoupler high-precision resistance regulator. Background Technique

[0002] With the improvement of people's living standards and the popularization of the national fitness campaign, more and more people use fitness equipment to exercise. There are a wide variety of fitness equipment on the market with different functions. Fitness bikes have received more and more attention because they can adjust the intensity during exercise to achieve the fitness effect.

[0003] In the prior art, a bicycle fitness device usually includes a bicycle rear wheel support frame and a resistance device. The friction wheel in the resistance device contacts the bicycle rear wheel to provide resistance to the bicycle rear wheel, so that the rider can obtain a riding resistance similar to that on the road surface when riding indoors, so as to achieve the purpose of riding indoors. However, most of the resistance adjustment methods of fitness bikes use wool felt to friction the inertia wheel of the bike as the movement resistance, and the guide rod structure adjusts the pressure between the wool felt and the large wheel to adjust the resistance of the bike. When using this method to adjust the resistance, the size of the resistance is unstable and the resistance cannot be accurately adjusted. As a result, when people simulate riding, the resistance is sometimes large and sometimes small, and an effective exercise effect cannot be achieved, and the resistance adjustment effect is poor. Therefore, a new type of vehicle-mounted optocoupler high-precision resistance regulator is needed. Summary of the Utility Model

[0004] The utility model mainly provides a vehicle-mounted optocoupler high-precision resistance regulator that is convenient for accurately adjusting the resistance and avoiding unstable resistance size.

[0005] To achieve the above object, the utility model adopts the following technical scheme: A vehicle-mounted optocoupler high-precision resistance regulator includes a first mounting plate and a metal wheel. A plurality of fixing rods are fixedly connected to the front surface of the first mounting plate at equal intervals. The front end surfaces of the plurality of fixing rods are fixedly connected with a second mounting plate. A threaded rod is rotatably connected between the inner surfaces of the first mounting plate and the second mounting plate. A threaded sleeve is threadedly rotated on the outer surface of the threaded rod. An installation disc is fixedly connected to the outer surface of the threaded sleeve. A friction block is arranged on the front surface of the installation disc. A motor is fixedly connected to the rear surface of the second mounting plate. The output end of the motor rotatably penetrates through the rear surface of the second mounting plate. The output end of the motor is fixedly connected with a driving gear. A driven gear is fixedly connected to the outer surface of the driving gear.

[0006] Compared with the prior art, the advantages and positive effects of the utility model are as follows.

[0007] 1. In the present utility model, the driving gear is rotated by a motor. When the driving gear meshes with the driven gear, under the action of the gear transmission ratio, the driven gear drives the threaded rod to rotate slowly, causing the mounting plate to move slowly towards the metal wheel along the two guide rods. The arc-shaped friction block fixedly arranged on the front surface of the mounting plate protrudes slightly and gradually rubs against the metal gear, playing a role in increasing the resistance. The speed sensor detects the rotation speed of the metal wheel and cooperates with the opto-relay to control the start and stop of the motor. The mounting plate stays stably on the surface of the threaded rod, enabling the friction block to continuously rub against the metal wheel, avoiding sudden changes in resistance when a person simulates cycling, which affects the exercise effect of the person, and improving the adjustment effect of the vehicle-mounted opto-coupled high-precision resistance regulator.

[0008] 2. In the present utility model, a protective case is fixedly arranged on the front surface of the second mounting plate. The inner side of the protective case is hollow and is located outside the driving gear and the driven gear, preventing people from accidentally touching the rotating gears and causing personal injuries. At the same time, it prevents external impurities from adhering between the gears, playing a protective role and improving the protection effect of the vehicle-mounted opto-coupled high-precision resistance regulator.

It should be noted that, without conflict, the embodiments of the present application and the features in the embodiments can be combined with each other.

[0015] Please refer toFigures 1-4 , the present utility model provides a technical solution: a vehicle-mounted optocoupler type high-precision resistance regulator, including a first mounting plate 1 and a metal wheel 15. A plurality of fixing rods 5 are fixedly connected to the front surface of the first mounting plate 1 at equal intervals. The front end surfaces of the plurality of fixing rods 5 are fixedly connected with a second mounting plate 7. A threaded rod 4 is rotatably connected between the inner walls of the first mounting plate 1 and the second mounting plate 7. A threaded sleeve 17 is threadedly rotatably connected to the outer surface of the threaded rod 4. An installation disc 2 is fixedly connected to the outer surface of the threaded sleeve 17. A friction block 3 is arranged on the front surface of the installation disc 2. A motor 8 is fixedly connected to the rear surface of the second mounting plate 7. The output end of the motor 8 rotatably penetrates through the rear surface of the second mounting plate 7. The output end of the motor 8 is fixedly connected with a driving gear 9. A driven gear 10 is fixedly connected to the outer surface of the driving gear 9.

[0016] As Figures 1-4 shown, the metal wheel 15 is located between the first mounting plate 1 and the second mounting plate 7. The metal wheel 15 and the friction block 3 are arranged in a matching manner. When the metal wheel 15 rotates between the first mounting plate 1 and the second mounting plate 7, when the friction block 3 moves forward, it will gradually rub the rear surface of the metal wheel 15 to increase the resistance.

[0017] As Figures 1-4 shown, a mounting block 12 is fixedly connected to the front surface of the second mounting plate 7. An optocoupler relay 13 is arranged on the front surface of the mounting block 12. By fixedly connecting the mounting block 12 to the front surface of the second mounting plate 7, the optocoupler relay 13 is fixedly arranged on the front surface of the mounting block 12 for use.

[0018] As Figures 1-4 shown, a speed sensor 14 is arranged on the inner surface of the second mounting plate 7. The speed sensor 14 and the metal wheel 15 are arranged in a matching manner, which is convenient for detecting the speed of the rotating metal wheel 15 through the speed sensor 14.

[0019] As Figures 2-3 shown, the threaded rod 4 rotatably penetrates through the front surface of the second mounting plate 7 and extends forward. The rear end surface of the driven gear 10 is fixedly connected to the front end surface of the threaded rod 4, which is convenient for the threaded rod 4 to extend forward and be fixedly connected to the rear end surface of the driven gear 10.

[0020] As Figures 1-3 shown, guide rods 6 are symmetrically fixedly connected to the opposite surfaces of the first mounting plate 1 and the second mounting plate 7. Sliding sleeves 16 are symmetrically fixedly connected to the inner surface of the installation disc 2. The sliding sleeves 16 and the guide rods 6 are arranged in a matching manner, which is convenient for guiding when the installation disc 2 moves by sliding the two sliding sleeves 16 on the outer surfaces of the two guide rods 6.

[0021] As Figures 1-2As shown in the figure, a protective case 11 is fixedly connected to the front surface of the second mounting plate 7. The driving gear 9 and the driven gear 10 are located inside the protective case 11. By fixedly arranging the protective case 11 on the front surface of the second mounting plate 7, it is convenient to protect the driving gear 9 and the driven gear 10, preventing personnel from accidentally touching the rotating gears and causing injuries.

[0022] Usage method and working principle of this device: When adjusting the resistance of the exercise bike, the first mounting plate 1 and the second mounting plate 7 are connected to each other through multiple fixing rods 5 and are fixedly installed near the metal wheel 15 of the exercise bike. After receiving the adjustment instruction, the opto-coupler relay 13 controls the start and stop of the motor 8. The output end of the motor 8 drives the driving gear 9 to rotate forward. The outer surface of the driving gear 9 meshes with and drives the driven gear 10, so that during the slow rotation of the driven gear 10, the threaded rod 4 rotates between the inner walls of the first mounting plate 1 and the second mounting plate 7. The mounting disc 2 will slide forward along the outer surfaces of the two guide rods 6 under the action of the threaded rotation connection between the threaded sleeve 17 and the threaded rod 4. The two sliding sleeves 16 fit and slide on the outer surfaces of the two guide rods 6, playing a role of guiding and limiting. The friction block 3 arranged on the front surface of the mounting disc 2 will gradually contact the surface of the metal wheel 15. The friction block 3 is made of wear-resistant material and will gradually increase the rotation resistance of the metal wheel 15 during the contact process. The speed sensor 14 arranged on the inner surface of the mounting block 12 detects the rotation speed of the rotating metal wheel 15, sends the data to the controller for calculation, and enables it to control the motor 8 to adjust the speed through the opto-coupler relay 13 to achieve high-precision adjustment. When a person uses the exercise bike, in the case of increasing resistance, it can accelerate the consumption of their own fat and exercise muscles, playing a role in fitness. The front surface of the second mounting plate 7 is fixedly provided with a protective case 11, the inside of which is hollow and is located outside the driving gear 9 and the driven gear 10, preventing personnel from accidentally touching the rotating gears and causing personal injuries. At the same time, it prevents external impurities from adhering between the gears, playing a protective role and improving the protection effect of the opto-coupler type high-precision resistance regulator for vehicles.
