Description

Technical Field

[0001] This application relates to the technical field of fitness equipment, and in particular to a stationary bike. Background Technology

[0002] As economic levels rise, people are paying more and more attention to their health. Due to the fast pace of life, most people choose to go to the gym or add fitness equipment to their homes. In addition to treadmills, exercise equipment such as stationary bikes, water bikes, and elliptical trainers are also very popular.

[0003] Indoor bicycles are similar to regular bicycles, including handlebars, a seat, a flywheel, and pedals. When riding an indoor bicycle, the rider holds the handlebars with both hands and pedals with both feet, but does not move like riding a regular bicycle. Exercise can be done in a small space. Indoor bicycles increase the exercise load by applying electromagnetic resistance to the rider (i.e., by adding magnets and a flywheel), thereby achieving the purpose of exercise.

[0004] People sweat a lot during exercise, especially when their hands are gripping the handlebars, which can become hot, sweaty, slippery, and sticky. Most indoor bike handlebars are made of metal, which makes them easy to slip when hands are wet. Some indoor bikes have rubber sleeves around the handlebars for anti-slip purposes, but these have poor heat dissipation and actually cause the exerciser's palms to sweat even more, requiring them to wipe away sweat constantly and affecting the exercise effect.

[0005] Regarding the aforementioned technologies, the inventors believe that there is a drawback in the poor heat dissipation of the handlebars of exercise bikes. Summary of the Invention

[0006] To improve the problem of poor heat dissipation of the handlebars of exercise bikes, this application provides an exercise bike.

[0007] This application provides a stationary bicycle, which adopts the following technical solution:

[0008] A stationary bicycle includes a frame, a seat, a flywheel, pedals for driving the flywheel to rotate, and handlebars symmetrically arranged on both sides of the frame. Each handlebar includes a first housing fixed to the frame and a second housing movably connected to the first housing. A fan is disposed inside the handlebar. A microswitch for controlling the opening and closing of the fan is disposed on the inner wall of the first housing. The second housing has a first ventilation opening and an actuating element is disposed on the second housing. When a person holds the handlebar, the second housing can be pressed close to the first housing, and the actuating element presses against the microswitch.

[0009] By adopting the above technical solution, when exercising, the user will grip the handles with both hands and place the second outer shell on the side of the palm. The user can then press the second outer shell against the first outer shell. The contact element inside the second outer shell will approach and press the micro switch. The micro switch can be electrically connected to the controller to start the fan. The fan blows air out through the first vent to cool and dissipate heat from the user's hand.

[0010] Optionally, the first housing is provided with an elastic element that drives the second housing away from the first housing.

[0011] By adopting the above technical solution, the first shell and the second shell are connected by an elastic element. When a person releases the handle, the second shell is driven by the elastic element to separate from the first shell, and the fan is in the off state. When a person holds the handle, the second shell is pressed close to the first shell, and the micro switch is pressed to turn on the fan.

[0012] Optionally, a limiting groove is provided on the upper part of the second housing, and a limiting part is provided inside the first housing to restrict the second housing from detaching from the first housing.

[0013] By adopting the above technical solution, the structure of the first shell and the second shell is more compact, which can improve the stability of the handle structure.

[0014] Optionally, a cover is connected to the end of the handle away from the frame, the cover has a second ventilation opening, and the fan is located inside the handle near the end of the cover.

[0015] By adopting the above technical solution, the fan blades can be installed with the back of the cover facing away. When the fan rotates, air is drawn in from the second vent and discharged from the first vent, thereby achieving the purpose of cooling the hands and making the fan more effective.

[0016] Optionally, the outer layer of the second outer shell is provided with a sweat-absorbing layer, and an avoidance opening is provided on the sweat-absorbing layer at the position corresponding to the first vent.

[0017] By adopting the above technical solution, the sweat-absorbing layer absorbs the sweat from the exerciser's palms while cooling down, and also reduces the possibility of hand slippage. In addition, the fan can speed up the drying speed of the sweat-absorbing layer.

[0018] Optionally, the elastic element is an elastic metal sheet, one side of which is connected to the end of the first housing near the second housing. The inner wall of the second housing is provided with a stop. When the second housing is away from the first housing, the surface of the metal sheet is in contact with the inner wall of the second housing and the side away from the first housing abuts against the stop. When the second housing is close to the first housing, the metal sheet is compressed and deformed, forming a cavity between it and the inner wall of the second housing.

[0019] By adopting the above technical solution, when a person releases the handle, the second outer shell is driven by the metal plate to separate from the first outer shell. The metal plate extends to fit against the inner wall of the second outer shell, and the first vent is blocked, reducing the possibility of dust and water entering the handle, extending the service life of the internal electrical components, and facilitating the cleaning of the handle after long-term use. When a person grips the handle, the second outer shell is pressed close to the first outer shell, and the metal plate is squeezed to form a cavity between itself and the inner wall of the second outer shell. The fan located at the end cap position can send air out through the cavity from the first vent.

[0020] Optionally, a bulge is provided on the inner wall of the second housing along the length of the handle, and the metal sheet has a recess in the middle that matches the bulge.

[0021] By adopting the above technical solution, through the bulge and the recess provided on the metal sheet, when the second outer shell approaches and squeezes the metal sheet, the metal sheet can stably extend and deform along the shape of the recess.

[0022] Optionally, a flexible sealing film is provided on the surface of the metal sheet facing the second housing.

[0023] By adopting the above technical solution, when the metal sheet is attached to the inner wall of the second outer shell, the sealing film can further play a role in preventing dust and water.

[0024] In summary, this application includes at least one of the following beneficial effects:

[0025] 1. The fan blows air out through the first vent to cool and dissipate heat from the exerciser's hands, reducing sweat production and improving exercise comfort;

[0026] 2. The movable second shell is placed on the side that is gripped in the palm. When the hand presses the second shell against the first shell, the contact element inside the second shell approaches and presses the micro switch. In this way, the micro switch only sends a signal to the controller to start the fan when there is movement, which ensures comfort and saves energy.

[0027] 3. When a person releases the handle, the metal plate extends to fit against the inner wall of the second housing, blocking the first vent, reducing the possibility of dust and water entering the handle, extending the service life of the internal electrical components, and facilitating cleaning of the handle after long-term use.

Detailed Implementation

[0034] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0035] Reference Figure 1 This application discloses a stationary bike, including a frame and a seat, a flywheel, pedals for driving the flywheel to rotate, and handlebars 1 symmetrically arranged on both sides of the frame. When riding the stationary bike, the exerciser holds the handlebars with both hands and pedals with both feet to rotate the bike.

[0036] Reference Figure 2 A fan 4 is installed inside the handlebar 1. A cover 7 is connected to the end of the handlebar 1 away from the frame. A first ventilation port 31 is opened on the surface of the handlebar 1, and a second ventilation port 71 is opened on the cover 7. The fan 4 is installed inside the handlebar 1 near the cover 7. The fan blades of the fan 4 can be installed with their backs to the cover 7. When the fan 4 rotates, air is drawn in from the second ventilation port 71 and discharged from the first ventilation port 31, thereby achieving the purpose of cooling the hand. The fan 4 has a better effect.

[0037] To ensure comfort during exercise while also being more energy-efficient, refer to Figure 2 and Figure 3The handle 1 includes a first housing 2 fixed to the frame and a second housing 3 movably connected to the first housing 2. A first vent 31 is formed on the second housing 3. A microswitch 5 controlling the opening and closing of the fan 4 is provided on the inner wall of the first housing 2. An actuating element 6 is provided on the first housing 2. When the exerciser grips the handle 1 with both hands, the second housing 3 can be positioned on the palm side. When the person grips the handle 1, it can drive the second housing 3 closer to the first housing 2, and the actuating element 6 presses against the microswitch 5. The microswitch 5 is electrically connected to a controller. When the microswitch 5 is pressed, it transmits a signal to the controller, which then starts the fan 4. In other embodiments, a battery can be installed on the first housing 2, and the microswitch 5 is electrically connected to the battery. When the actuating element 6 presses against the microswitch 5, the fan 4 is connected to the power supply and begins to work.

[0038] The specific connection method between the first outer shell 2 and the second outer shell 3 is as follows: Figure 2 The first outer shell 2 is provided with an elastic element that drives the second outer shell 3 away from the first outer shell 2. A limiting groove 21 is formed on the first outer shell 2, which can be located on the inner or outer wall of the first outer shell 2. The second outer shell 3 is provided with a limiting part 32 that restricts the second outer shell 3 from detaching from the first outer shell 2. The elastic element can be a spring, rubber pad, metal, or other elastic material. When a person releases the handle 1, the second outer shell 3 is driven away from the first outer shell 2 by the elastic element, and the fan 4 is in the off state. When a person grips the handle 1, the second outer shell 3 is pressed closer to the first outer shell 2, triggering the microswitch 5 to turn on the fan 4.

[0039] Furthermore, refer to Figure 2 The outer layer of the second outer shell 3 is provided with a sweat-absorbing layer 8. An avoidance opening 81 is provided on the sweat-absorbing layer 8 at the position corresponding to the first ventilation opening 31. The sweat-absorbing layer 8 can be a sponge layer or cotton cloth with water absorption properties. While cooling down, the sweat-absorbing layer 8 absorbs the sweat from the exerciser's palms and can also reduce the possibility of hand slippage. In addition, the fan 4 can also speed up the drying speed of the sweat-absorbing layer 8.

[0040] In a preferred embodiment, the elastic element is an elastic metal sheet 9, which can be two, left and right. A stop 33 along the length of the handle 1 is provided in the middle of the inner wall of the second outer shell 3. One side of the metal sheet 9 is connected to the end of the first outer shell 2 near the second outer shell 3, and the other side abuts against the stop 33. A bulge 34 is provided on the inner wall of the second outer shell 3 along the length of the handle 1. A recess 91 matching the bulge 34 is provided in the middle of the metal sheet 9. A flexible sealing film 10 for dust and water protection is provided on the surface of the metal sheet 9 facing the second outer shell 3. Optionally, but not limited to, a sealing gasket can be provided between the contact surfaces of the first outer shell 2 and the second outer shell 3. A sealing sheet can also be provided between the end cap and the handle 1. The sealing sheet has a through hole consistent with the second vent 71. The end cap and the handle 1 are rotatably connected. When the handle 1 needs to be cleaned, the end cap can be rotated to misalign the through hole with the second vent, thereby sealing the end cap.

[0041] Reference Figure 4 and Figure 5 When a person releases the handle 1, the second outer shell 3 is driven by the metal sheet 9 to separate from the first outer shell 2. The metal sheet 9 extends to fit against the inner wall of the second outer shell 3, blocking the first vent 31, reducing the possibility of dust and water entering the handle 1, extending the service life of the internal electrical components, and facilitating cleaning of the handle 1 after long-term use. When a person grips the handle 1, the second outer shell 3 is pressed close to the first outer shell 2, and the metal sheet 9 is squeezed to form a cavity between itself and the inner wall of the second outer shell 3. The fan 4, located at the end cap, can send air out through the cavity from the first vent 31. Furthermore, through the cooperation of the bulge 34 and the recess 91, when the second outer shell 3 and the first outer shell 2 approach and compress the metal sheet 9, the metal sheet 9 can stably extend and deform along the shape of the recess 91.

[0042] The implementation principle of a stationary bike according to an embodiment of this application is as follows:

[0043] When a user rides a stationary bike, they hold the handlebars with both hands and pedal with both feet. The sweat-absorbing layer 8 absorbs sweat from the palms. The second outer shell 3 is pressed close to the first outer shell 2. The trigger 6 presses the micro switch 5 to start the fan 4, and the metal plate 9 is squeezed to form a cavity between itself and the inner wall of the second outer shell 3. When the fan 4 rotates, it draws air in from the second vent 71 and exhausts it through the cavity to the first vent 31, thereby cooling the hands and drying the sweat-absorbing layer 8. When the user releases the handlebars 1, the second outer shell 3 is driven by the metal plate 9 to separate from the first outer shell 2. The micro switch 5 is turned off, turning off the fan 4. The metal plate 9 extends to fit against the inner wall of the second outer shell 3, blocking the first vent 31. This reduces the possibility of dust and water entering the handlebars 1, extends the service life of the internal electrical components, and facilitates cleaning of the handlebars 1 after long-term use.

[0044] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
