Description

Technical Field

[0001] This utility model relates to the field of fitness equipment technology, and in particular to a braking device for fitness equipment and fitness equipment with the braking device. Background Technology

[0002] Indoor cycling bikes are widely popular as an indoor fitness device that simulates cycling. They not only specifically target leg muscles but also effectively engage the hip, waist, back, and arm muscles, significantly improving cardiovascular function. Their structure is similar to a regular bicycle, including handlebars, seat, pedals, and wheels, all securely connected. To simulate a realistic cycling experience, indoor cycling bikes typically feature resistance devices at the front wheel, commonly inertia wheels or magnetic control wheels.

[0003] However, when exercise ends or emergency braking is required, the inertia of the resistance wheels may cause the user's legs to continue moving, thus posing a risk of injury. In addition, in some scenarios (such as temporarily locking the resistance wheels to prevent accidental activation), it is necessary for the bicycle to remain in a braking state.

[0004] Currently, most indoor cycling bikes on the market use lever mechanisms for braking: the brake cable connects to one end of the lever, and the other end uses a friction resistance wheel to achieve braking. However, this design has drawbacks: First, complete stopping in a short time often requires considerable force, making the braking process relatively time-consuming. More inconveniently, due to the generally lack of a self-locking function, users must continuously apply force to the brake mechanism to maintain braking, which undoubtedly reduces ease of use and comfort. Second, prolonged friction braking can easily lead to accelerated localized wear of the brake pads, thus affecting braking performance and lifespan. Therefore, these shortcomings of existing braking systems urgently need improvement to enhance the safety and user experience of indoor cycling bikes. Utility Model Content

[0006] This utility model is achieved using the following solution:

[0007] This utility model proposes a braking device for fitness equipment, which is used in fitness equipment with a resistance wheel. The braking device includes a fixing member, a swing arm, a connecting rod, and an operating rod. The fixing member is hinged to a first end of the swing arm and a first end of the operating rod. The second end of the swing arm is hinged to a first end of the connecting rod, and the second end of the connecting rod is hinged to the middle of the operating rod, thereby forming a four-bar linkage between the fixing member, the swing arm, the connecting rod, and the operating rod. The swing arm has a first side facing the resistance wheel, and a brake pad is provided on the first side. The second end of the operating rod can be operated to move the brake pad toward the resistance wheel, and the brake pad is used to contact and compress the surface of the resistance wheel.

[0008] In one embodiment, the operating lever includes a first lever portion and a second lever portion, which are connected at an angle to form a protrusion at the connection; the swing arm has a second side portion opposite to the first side portion, and the second side portion is recessed with a limiting recess; the protrusion portion can abut against and cooperate with the limiting recess, and the four-bar linkage correspondingly forms a self-locking mechanism.

[0028] To further illustrate the various embodiments, the present invention provides accompanying drawings. These drawings are part of the disclosure of the present invention and are mainly used to illustrate the embodiments, and can be used in conjunction with the relevant descriptions in the specification to explain the operating principles of the embodiments. With reference to these drawings, those skilled in the art should be able to understand other possible implementations and the advantages of the present invention. Components in the drawings are not drawn to scale, and similar component symbols are generally used to represent similar components.

[0029] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments.

[0030] like Figures 1-8 As shown, this embodiment provides a fitness equipment 1, specifically a stationary bike. The fitness equipment 1 includes a main frame 10, which serves as the mounting base for other components. A foot pedal assembly 20 is pivotally mounted on the main frame 10. The foot pedal assembly 20 has a pivot shaft 21, and is pivotally mounted to the main frame 10 via the pivot shaft 21. A drive wheel 30 is coaxially connected to the pivot shaft 21. The drive wheel 30 is driven by a resistance wheel 40. In this embodiment, the drive wheel 30 is specifically a pulley, and is driven by a belt 31 to the resistance wheel 40. The resistance wheel 40 can be a magnetically controlled wheel or an inertia wheel, etc. Both the drive wheel 30 and the resistance wheel 40 are pivotally mounted on the main frame 10. The main frame 10 is equipped with armrests 70 and a seat cushion 60. The main frame 10 is covered with a shell 80, which encloses components such as the transmission wheel 30, the resistance wheel 40, and the brake device 50, thus providing protection for the user.

[0031] A braking device 50 is also installed on the main frame 10. The braking device 50 can act on the resistance wheel 40 to stop the resistance wheel 40. The braking device 50 includes a fixing member 51, a swing arm 52, a connecting rod 54, and an operating lever 55. The fixing member 51 is fixedly connected to the main frame 10. The swing arm 52 and the operating lever 55 are hinged to the fixing member 51. The first end 521 of the swing arm 52 is hinged to the fixing member 51 through a first hinge point C, and the first end 551 of the operating lever 55 is hinged to the fixing member 51 through a second hinge point D. The first hinge point C and the second hinge point D are correspondingly spaced on the fixing member 51.

[0032] The second end 522 of the rocker arm 52 is hinged to the first end of the connecting rod 54 via the third hinge point E. The second end of the connecting rod 54 is hinged to the middle of the operating rod 55 via the fourth hinge point F, thus forming a four-bar linkage between the fixing member 51, the rocker arm 52, the connecting rod 54, and the operating rod 55. The rocker arm 52 has a first side 523 opposite to the resistance wheel 40, and the first side 523 is provided with a brake pad 53. The brake pad 53 can be made of a flexible material, such as brake leather, thereby improving the braking effect on the resistance wheel 40. Figure 4As shown, by pushing or pulling the second end 552 of the operating lever 55 along the N direction, the operating lever 55 rotates around the second hinge point D. The rotation of the operating lever 55 drives the swing arm 52 to swing along the M direction via the connecting rod 54. The first side 523 of the swing arm 52 approaches the surface of the resistance wheel 40, causing the brake pad 53 to move towards the resistance wheel 40. The brake pad 53 contacts and presses against the surface of the resistance wheel 40, achieving a braking effect. The brake pad 53 achieves a braking effect on the resistance wheel 40 through the linkage of the four-bar linkage mechanism. The four-bar linkage mechanism can save effort and make operation more convenient.

[0033] like Figure 5 As shown, when the second end 552 of the operating lever 55 moves continuously in the N direction, and the second hinge point D, the fourth hinge point F and the third hinge point E are on the same straight line, the swing arm 52 swings to the limit position in the M direction, and the braking force of the brake pad 53 on the resistance wheel 40 reaches the maximum, which can achieve the fastest braking stop.

[0034] Reference Figures 2-7 In this embodiment, the operating lever 55 includes a first lever portion 553 and a second lever portion 554, which are connected at an angle, for example, in an L-shape, thereby forming a protrusion 556 at the connection. The swing arm 52 has a second side surface 524 opposite to the first side surface 523, and the second side surface 524 is recessed with a limiting recess 525. When the second end 552 of the operating lever 55 moves continuously in the N direction, and the second hinge point D, the fourth hinge point F, and the third hinge point E are aligned on the same straight line, the second end 552 of the operating lever 55 can continue to move a short distance in the N direction, so that the protrusion 556 abuts against the limiting recess 525, and the four-bar linkage correspondingly forms a self-locking mechanism. Without the need to continuously apply external force to the braking mechanism, the brake pad 53 can form a continuous braking effect on the resistance wheel 40, making operation more effortless and improving the user experience.

[0035] In this embodiment, the second end 552 of the operating lever 55 is connected to a brake cable 12. The brake cable 12 is used to pull the second end 552 of the operating lever 55, causing it to move in the N direction. The second end 552 of the operating lever 55 has a brake cable mounting part 555 provided by bending, which is used to connect one end of the brake cable 12. The brake cable 12 is slidably disposed in the sliding sleeve 13, which is mounted on the brake sliding sleeve mounting seat 11. The brake sliding sleeve mounting seat 11 is fixedly mounted on the main frame 10. The brake cable 12 is connected to a remote control mechanism, which can pull the brake cable 12, thereby facilitating the operation of the braking device 50.

[0036] In this embodiment, the brake pad 53 is disposed opposite to the outer peripheral surface of the resistance wheel 40, allowing the brake pad 53 to directly act on the outer peripheral surface of the resistance wheel 40, thus resulting in a better braking effect. In other embodiments, the brake pad 53 may act directly on the side of the resistance wheel 40, however, the braking effect of this method is slightly inferior to that of the brake pad 53 acting directly on the outer peripheral surface of the resistance wheel 40.

[0037] In this embodiment, the brake pad 53 is connected within the region between the first hinge point C and the third hinge point E of the rocker arm 52. In other embodiments, the brake pad may be connected outside the region between the first hinge point C and the third hinge point E of the rocker arm 52; for example, the brake pad may be connected to a portion of the rocker arm 52 extending outward from the second end 522 beyond the third hinge point E. This method can increase the travel of the brake pad, but reduces the braking force exerted by the brake pad on the resistance wheel 40. In this embodiment, the brake pad 53 is connected within the region between the first hinge point C and the third hinge point E of the rocker arm 52, resulting in a greater braking force on the resistance wheel 40, better braking effect, and further effort-saving effect.

[0038] The second end 552 of the operating lever 55 can be connected to a reset mechanism. The reset mechanism can reset the four-bar linkage, causing the brake pad 53 to disengage from the resistance wheel 40. The reset mechanism is, for example, a reset spring (not shown). The reset spring is connected between the brake sleeve mounting base 11 and the brake cable mounting part 555. The elastic force of the reset spring causes the second end 552 of the operating lever 55 to move in the opposite direction to the N direction. The structure is simple, the operation is convenient, and it can achieve automatic reset.

[0039] Although the present invention has been specifically shown and described in conjunction with preferred embodiments, those skilled in the art should understand that various changes in form and detail may be made to the present invention without departing from the spirit and scope of the present invention as defined in the appended claims, and all such changes shall be within the scope of protection of the present invention.
