Description

Technical Field

[0001] The utility model belongs to the technical field of treadmills, and in particular relates to a treadmill braking device. Background Art

[0002] The treadmill is a common fitness equipment in homes and gyms. It is the simplest type of home fitness equipment today and the best choice for home fitness equipment.

[0003] In the prior art, a treadmill frame is generally provided with a plurality of wheels, which are rotatably connected to the frame, and a brake mechanism for locking the wheels is also provided on the frame. However, the brake mechanism in the prior art only locks one wheel, resulting in poor locking performance of the brake mechanism of the treadmill, posing a safety hazard. Utility Model Content

[0004] The utility model provides a treadmill brake device, aiming to solve the problems of poor locking performance and potential safety hazards of the brake mechanism of the treadmill in the prior art.

[0005] In order to solve the above technical problems, the technical solution adopted by the utility model is:

[0006] A treadmill brake device comprises a frame and a wheel rotatably connected to the frame;

[0007] The frame is also provided with a brake assembly for locking the wheels;

[0008] The brake assembly includes a brake pad and a driving mechanism for driving the brake pad to lock or release the wheel;

[0009] There are at least two brake pads, each of which corresponds to one wheel, and a linkage device is provided between two adjacent brake pads to simultaneously lock or release the wheels.

[0010] A further improved solution: the brake pad is rotatably connected to the frame, a rotating shaft is provided on the frame, and one end of the brake pad is rotatably connected to the rotating shaft.

[0011] Based on the above technical solution: the brake pad is rotatably connected to the frame, the brake pad and the frame are easy to assemble, and when driving the brake pad to loosen or lock the wheel, it is only necessary to rotate the brake pad by a certain angle, and the brake pad does not need to move in a straight line, thereby simplifying the structure of the driving mechanism.

[0012] A further improved solution: an elastic member for pulling the brake pad to release the wheel is further provided between the frame and the brake pad.

[0013] Based on the above technical solution: an elastic member for pulling the brake pad to loosen the wheel is also provided between the frame and the brake pad, and the elastic member is used to separate the brake pad from the wheel, thereby realizing the function of loosening the wheel.

[0014] A further improved solution: the elastic member is a spring, one end of the spring is fixed to the frame, and the other end of the spring is fixed to an end of the brake pad away from the rotating shaft.

[0015] Based on the above technical solution: the elastic member is a spring, the spring has a simple structure and low use cost, so that the elastic member has a low use cost.

[0016] A further improved solution: the linkage device is a linkage rod.

[0017] Based on the above technical solution: the linkage device is a linkage rod, which connects two brake pads together. When one brake pad moves, the other brake pad also moves under the action of the linkage rod. One driving mechanism can drive multiple brake pads, reducing the number of driving mechanisms.

[0018] A further improved solution: the brake pad is rotatably connected to the linkage rod, and the linkage rod is arranged at an end of the brake pad away from the rotating shaft.

[0019] Based on the above technical solution: the brake pad is rotatably connected to the linkage rod. Since the movement of the brake pad is to swing within a certain angle, the brake pad is rotatably connected to the linkage rod. There will be no interference between the brake pad and the linkage rod, which improves the stability of the linkage during operation.

[0020] A further improved solution: the cross-section of the linkage rod is in a polygonal shape.

[0021] Based on the above technical solution: the cross-sectional shape of the linkage rod is a polygon, the cross-sectional shape of the linkage rod is a polygon, the linkage rod has a higher bending strength, and the linkage rod is not easy to bend.

[0022] A further improved solution: the driving mechanism includes a screw rod arranged on the frame, the brake pad includes a sheet body in contact with the wheel and a frame body arranged on the sheet body, and a contact plate in contact with the screw rod is arranged at one end of the frame body away from the sheet body.

[0023] Based on the above technical solution: the driving mechanism includes a screw rod arranged on the frame, and the screw rod drives the plate body to rotate through the frame body, thereby using the entire brake pad to rotate within a certain angle. The screw rod has a self-locking property and will not loosen automatically after the screw rod is rotated, so that the driving mechanism does not need to be provided with an independent locking mechanism, thereby simplifying the structure of the driving mechanism.

[0024] A further improved solution: a spherical head is provided at one end of the screw rod that contacts the contact plate, and the spherical head is in point contact with the contact plate.

[0025] Based on the above technical solution: the spherical shape is in point contact with the contact plate, the spherical head and the contact plate have a smaller contact area, and the contact plate is not easy to wear.

[0026] A further improved solution: the frame is provided with an axis hole which cooperates with the rotating shaft.

[0027] Based on the above technical solution: the frame is provided with an axis hole matched with the rotating shaft, so that the frame and the rotating shaft are easy to assemble.

[0028] The beneficial effects of the utility model are:

[0029] The utility model provides at least two brake pads, each of which corresponds to one wheel, and a linkage is provided between two adjacent brake pads to lock or release the wheels at the same time. The driving mechanism can drive multiple brake pads to move at the same time, so that multiple brake pads can lock multiple wheels, so that the braking mechanism has better braking performance, improves the stability of the treadmill braking device, and improves the safety performance of the treadmill braking device.

The rotating shaft 34 can be an integrated structure with the frame 1, the rotating shaft 34 can also be welded to the frame 1, and the rotating shaft 34 can also be fixed to the frame 1 by threads.

[0044] A rolling bearing may be provided between the brake pad 31 and the rotating shaft 34 to allow the brake pad 31 to rotate flexibly relative to the rotating shaft 34 .

[0045] refer to Figures 1 to 4 , wherein: an elastic member 35 for pulling the brake pad 31 to release the wheel 2 is also provided between the frame 1 and the brake pad 31 .

[0046] The elastic member 35 is a spring, one end of which is fixed to the frame 1 , and the other end of which is fixed to an end of the brake pad 31 away from the rotating shaft 34 .

[0047] One end of the spring can be hung on the frame 1, and the other end of the spring can be hung on the brake pad 31. Both the frame 1 and the brake pad 31 can be provided with hanging holes for hanging the spring.

[0048] Wherein: the linkage device 33 is a linkage rod.

[0049] The brake pad 31 is rotatably connected to the linkage rod, and the linkage rod is disposed at one end of the brake pad 31 away from the rotating shaft 34 .

[0050] A shaft body may be arranged on the linkage rod, a hole body matching with the shaft body may be arranged on the brake pad 31, and a limit head may be arranged on the shaft body through a thread to prevent the brake pad 31 from being separated from the shaft body.

[0051] Wherein: the cross-sectional shape of the linkage rod is a polygon. The linkage rod with a polygonal cross-sectional shape has a higher bending strength, and the linkage rod is not easy to bend during long-term use. The linkage rod can also be replaced by other structures, for example, the linkage rod can be a hollow tube.

[0052] Specifically, the driving mechanism 32 includes a screw rod 36 disposed on the frame 1, the brake pad 31 includes a sheet body 37 in contact with the wheel 2 and a frame body 38 disposed on the sheet body 37, and a contact plate 39 in contact with the screw rod 36 is disposed at one end of the frame body 38 away from the sheet body 37.

[0057] The working principle of this embodiment:

[0058] During normal use, the spring pulls the brake pad 31 to separate from the wheel 2, and the brake pad 31 is not in contact with the wheel 2, and the wheel 2 can rotate.

[0059] When braking is required, the screw 36 is rotated, and the ball shape on the screw 36 contacts the contact plate 39, and the movement of the screw 36 drives the contact plate 39 to rotate. The rotation of the contact plate 39 drives the entire brake pad 31 to rotate, and the brake pad 31 overcomes the force of the spring during the rotation process.

[0060] When one of the brake pads 31 rotates, the other brake pads 31 are driven to rotate through the linkage rod, so that multiple brake pads 31 can lock multiple wheels 2.

[0061] When braking is not needed, the screw rod 36 is rotated in the opposite direction, and the spring drives the brake pad 31 to rotate in the opposite direction, so that the plate body 37 of the brake pad 31 is out of contact with the wheel 2 to release the wheel 2.

[0062] The present utility model is not limited to the above optional implementation modes. Under the premise of not conflicting with each other, the various schemes can be combined arbitrarily. Anyone can derive other forms of products under the inspiration of the present utility model. However, no matter what changes are made in their shapes or structures, all technical schemes that fall within the scope defined by the claims of the present utility model fall within the protection scope of the present utility model.
