Description
Technical Field
The invention relates to the technical field of body-building training equipment, in particular to a detachable platform type bicycle exercise training device.
Background
At present, the public body building exercise is many, but most projects need to have certain physical stamina, such as running, badminton and the like, and some are very boring, such as walking and the like, only riding has a wide public foundation, the physical stamina is not hurt, the knee is not hurt, the physical stamina requirement is not very high, and people can ride according to own conditions.
The key of the problems is that at present, no proper place exists for riding, no off-road experience exists for riding in cities, the riding is basically plane, the riding is very unsafe, people and vehicles on many road sections are mixed, and continuous riding cannot be performed at all; in addition, the northern climate makes riding impossible in winter, so that riding lovers need to pause when entering winter.
The data show that riding for 10 km at 15 km per hour consumes 2 km of jogging calories, but many people cannot run for 2 km at all, and riding for 10 km can be completed easily, so that riding is the sports item most suitable for mass body building.
Only the bicycle simulation trainer is adopted, so that the user can exercise the bicycle in spring, summer, autumn and winter whenever and wherever possible.
Generally, two different types of bicycle trainers are known and commonly used. The first class of exercise machines (also known as turbo-trainers) is a piece of equipment that enables a bicycle to be ridden while the bicycle remains stationary. Such exercise machines typically include a frame, a clamp that securely holds the bicycle, a roller that presses upward against the rear wheel of the bicycle, and a mechanism that provides resistance as the pedals are turned. These trainers are categorized by how the unit provides resistance to the wind, magnetic, fluid, centrifugal, and utility trainers. In all of these first class trainers, the bicycle is fixedly mounted to the trainer and remains completely stationary during training. Typically, the trainer is fixedly mounted to the rear axle of the bicycle. A completely different type of bicycle trainer is the so-called bicycle roller, which is not attached to the bicycle frame unlike other types of bicycle trainers. These bicycle rollers generally comprise three cylinders, drums or rollers, two for the rear wheel and one for the front wheel, on top of which the bicycle is riding. The belt may connect one of the rear rollers to the front roller, causing the front wheel of the bicycle to rotate while pedaling. During training, the rider must balance himself/herself on the rollers.
Each type of bicycle trainer has certain advantages and disadvantages. Riding on a stationary bicycle trainer never provides the feel of riding a bicycle in practice, as the bicycle remains completely stationary. However, in practice during riding a bicycle, the pedaling action is usually compensated for by slightly tilting the bicycle with respect to the vertical, in particular during full speed. When the bicycle rollers do not allow such tilting movement, balancing the bicycle without leaving the rollers is a considerable challenge for the rider and requires more balancing and attention than the bicycle trainer.
US2009/0075785A1 describes another type of sports bicycle trainer which is suitable for use with a sports bicycle. The trainer includes a base and a frame having spaced apart ends adapted to engage and support a bicycle. The pivot assembly is coupled to the central portion of the frame and the base. The pivot assembly allows movement between the frame and the base and includes a biasing mechanism that resists tilting of the frame relative to the base. The frame is supported only by the pivot assembly. The frame of the bicycle trainer is mounted to the rear axle of the bicycle by means of a coupling.
This mounting of the rear axle to the bicycle trainer is disadvantageous because the biasing force against the tilting of the frame relative to the base is transferred to the bicycle via the rear wheels, which are free to move under actual riding conditions. Furthermore, because a majority of the weight of the bicycle and rider is carried by the frame (via the coupling) rather than the rollers, the tilting movement feel of the bicycle on the bicycle trainer is less natural than riding a bicycle on a road. In particular, because the rollers do not directly support the weight of the bicycle and the user, the tires of the rear wheels may slip during acceleration and thus the bicycle may not generate the same power output as a bicycle that can be implemented on a road.

Working principle of detachable platform type bicycle exercise trainer:
1. for example, the mountain bike is used for exercise training, the mountain bike with 24-speed, 27-speed, 30-speed, 26-inch and 27-inch hubs in different sizes can be adapted to the training machine, tire air is firstly discharged during installation, front and rear wheels are put into a tire fixer and then inflated, and a fastening screw rod is adjusted, so that the friction force between the mountain bike and a rubber driving ball 33 is close to the friction force of the mountain bike running on a gentle asphalt road surface.
The mountain bike support bar 11 is of a universal joint structure, can provide fixed support force for mountain bike, has no space for supporting and linking at the bottom of part of brands of mountain bike, and can be linked by using screws.
Another function of the mountain bike support bar 11 is to provide a variable angle for the mountain bike to go up and down a slope and also to provide a left and right deviation of the center when the mountain bike is turned, so that the rider can feel a real riding feeling.
2. VR vision 9, alternatively referred to as VR glasses or VR helmets, provides two videos for the rider, one being a game video and the other being a riding video recorded in the rider's primary field of view.
3. Taking video as an example, the working principle of the simulator is described:
the person of riding uses the VR helmet, and the starting point that video broadcast got into the horizontal segment begins to ride, and when riding the starting point of ascending section, VR gave the ascending signal, and central processing unit 8 starts elevating platform lift actuating mechanism after receiving the signal, because is analog video, the slope at this point can design in advance, if this slope is 30 degrees, elevating platform lift actuating mechanism begins work, and the workstation front end rises, forms 30 degrees angles with the horizontal line, and the person of riding can feel the degree of difficulty of ascending.
At this time, since the front wheel of the mountain bike is lifted, the rider can obviously feel that the center is shifted backward, at this time, the rider can adjust the speed using the transmission, the speed sensor on the rear wheel senses the speed change and sends a signal to the central processor, and the central processor controls the tire holder to increase or decrease the friction.
After entering the top point of the video simulation slope section and being the starting point of the second section flat road, the VR equipment gives out a signal, and the central processing unit controls the lifting platform to lift the driving mechanism, so that the front wheel is lowered to the horizontal plane, and a rider rides horizontally; after entering the video simulation second section flat road end point and being the starting point of the downhill section, assuming that the downhill slope of the point D is 25 degrees, VR equipment sends out signals, and the central processing unit controls the lifting driving mechanism of the lifting platform to lift the rear wheels so that the rear wheels form an angle of 25 degrees with the horizontal plane, and meanwhile, the tire fixer reduces friction force, so that a rider can feel relaxed when the rider descends.
E, entering the point E, and enabling the servo motor to work so as to enable the rear wheel to be lowered to the horizontal plane.
4. The video simulation can be added into a curve, when the video display of a rider is about to enter the curve, as shown in the above diagram, the rider can make a handle right after entering a first turning point, the gravity center is cheaper left, the riding experience is more real, the rider returns to the positive direction to go straight after entering the first turning end point, the rider enters a second turning start point to make a handle left after entering the second turning end point, and the rider returns to the positive direction after entering the second turning end point.
In the curve section, the air blowing port can respectively convey tastes of the two scenes according to grasslands and forests, so that riding is more nearly real.
5. According to different body-building requirements, videos with different time and different difficulty can be manufactured respectively, and a rider can select scene videos with different time and different difficulty to train according to physical ability; the simulation video with certain difficulty can be manufactured, and particularly the mountain bike cross-country obstacle is reflected to stimulate the mountain bike riding. Such video is generally mainly video shot from a main view angle, each node is set in the video in advance, and a program is programmed so that a central computer can adjust according to the nodes.
6. The simulated video is produced, the background is changed along with the change of the depth of field through the collocation of different scenes, but the road surface is always right in front, and the rider can feel by himself. The mountain bike can be ridden, particularly a bumpy road surface, and a servo motor and a driving belt can be added, so that the mountain bike can generate a real bumpy feeling on the simulator.
7. The mountain bike support bar 11 can be linked with the mountain bike by using a universal joint, however, the mountain bike needs to be welded with a connecting point, if so, the mountain bike is not easy to replace after being installed, and therefore, the soft-tailed mountain bike and the hard-tailed mountain bike can be respectively manufactured into simulators; the catcher can be welded at the top end of the connecting rod, and the mountain bike frame is fastened by the catcher, so that the mountain bike can be replaced at any time, and one simulator can use different kinds of mountain bike and even road racing bike.
Rubber balls in the front wheel fixer are added with a servo motor, one rubber ball of the front wheel is directly connected with the motor and driven by the motor to rotate, so long as the motor is ridden, a speed sensor of the rear wheel sends out a signal, a central control processor controls the motor to work, the front wheel starts to rotate, riding is stopped, the speed sensor sends out a prohibition signal, and the central control processor controls the motor to stop rotating.
When the simulator simulates an ascending and descending slope, because of gravity, the simulator can generate the feeling of difficulty in climbing and easiness in descending slope in actual riding, but the simulator cannot display the feeling, so that the friction force is properly increased and reduced for the rear wheel driving wheel to achieve the feeling of ascending and descending slope.
One end of the wheel fixing rubber driving ball fastening screw rod is connected with a servo motor, the central processing unit controls the servo motor to start working when ascending, and the servo motor drives the screw rod to enable the clamping piece to push the driving ball to shrink towards the tire direction, so that friction resistance is increased, and climbing difficulty is improved; when the tire is in a downhill slope, the servo motor works reversely to drive the screw rod to move outwards, the rubber ball is pulled by the clamping piece to be contacted and separated with the tire, and at the moment, the tire is not stressed any more, so that the downhill slope feel is generated.
At this time, another advantage shows that the original derailleur of mountain bike can use, especially when going up and down the slope, the person of riding often reaches the effect that reduces the burden of riding through the transformation speed, and increase this small-size servo motor and lead screw for the effect that the speed change of riding really has realized the reduction reality and experienced, gives the different speed of central computer through the speed sensor after the speed change, and central computer control servo motor and hydraulic stem give different pressure (resistance) feedback, and the person of riding can increase through the resistance rapidly and reduce and experience the speed change effect.
The foregoing is merely a preferred embodiment of the present invention, and it should be noted that it will be apparent to those skilled in the art that several modifications and variations can be made without departing from the technical principle of the present invention, and these modifications and variations should also be regarded as the scope of the invention.
