[0033] In the present utility model, a positioning connection component is used to achieve accurate, rapid, and reliable installation of the bracket on the riding platform housing 10. By providing anti-fooling ribs 21 at the inner edge of the installation groove, the anti-fooling ribs 21 are used for anti-error positioning of the installation of the infrared sensor 20, enabling accurate and effective installation of the infrared sensor 20, such that the probe 23 of the infrared sensor 20 can just correspond to the transparent patch 31 on the cover plate 30. By providing the transparent patch 31, the infrared rays emitted by the probe 23 of the infrared sensor 20 can be effectively emitted, ensuring the effectiveness of the detection by the infrared detection component.

[0034] The edge of the riding platform housing 10 is circumferentially provided with a folded edge 11, and the folded edge 11 extends obliquely towards the direction of the crank pedaling assembly.

[0042] In this embodiment, the shape of the installation opening 12 is adapted to the shape of the first support plate 41. The projection of the installation opening 12 is a quadrilateral, including two parallel long sides and two non-parallel short sides. Through the above settings, an anti-fooling positioning function can be achieved, enabling the support to be installed in the installation opening 12 in only one orientation, and enabling the infrared detection component to be accurately installed in the installation opening 12.

[0043] In this embodiment, the four corners of the installation opening 12 are all rounded, and the four corners of the corresponding first support plate 41 are also all rounded, thereby facilitating the insertion and cooperation of the first support plate 41 in the installation opening 12.

[0044] In other preferred embodiments, the projections of the installation opening 12 and the first support plate 41 can also be rectangular, circular or other shapes, which are not specifically limited herein.

[0045] An installation plate 43 is connected to the inclined waist of the second support plate 42, and the installation plate 43 is arranged obliquely along the inclined waist of the second support plate 42.

[0046] As Figure 5 shown, the dotted line is parallel to the plane where the cover plate 30 is located (the plane where the cover plate 30 is located and the plane where the first support plate 41 is located). The included angle α between the installation plate 43 and the plane where the first support plate 41 is located and the included angle between the folding edge 11 and the riding platform housing 10 are complementary, which facilitates the installation and connection of the installation plate 43 on the folding edge 11.

[0048] During installation, the first support plate 41 can be inserted and fitted into the installation opening 12 from the inside of the folding edge 11, and the cover plate 20 is basically flush with the plane where the second installation opening 12 is located; the second support plate 42 and the installation plate 43 are located inside the folding edge 11 and do not extend out of the installation opening 12, and the installation plate 43 is installed and connected to the inside of the folding edge 11, so that the support is installed on the folding edge 11.

[0049] A positioning and connecting component is provided between the installation plate 43 and the folding edge 11. The positioning and connecting component includes a positioning hole 44 and a connecting hole 45 provided on the installation plate 43, and a positioning post 13 and a connecting post 14 provided on the inner side of the folding edge 11; the positioning post 13 is fitted in the positioning hole 44, and the connecting post 14 is fixedly connected to the connecting hole 45 by a screw, so that the installation plate 43 is connected to the folding edge 11, and further the support can be installed on the folding edge 11, which facilitates the installation and disassembly of the support.

[0050] In this embodiment, the number of the positioning posts 13 is two, and the two positioning posts 13 are respectively located at both ends of the mounting opening 12; the number of the connecting posts 14 is two, and the two connecting posts 14 are respectively located at both ends of the mounting opening 12.

[0051] In this embodiment, the positioning posts 13 protrude from the inner side surface of the folding edge 11. The positioning posts 13 can be cross-shaped protrusions, and the cross-shaped protrusions can produce slight extrusion deformation, which is convenient for realizing the positioning and insertion of the positioning posts 13 and the positioning holes 44; through the cooperation of the positioning posts 13 and the positioning holes 44, the installation of the bracket in the mounting opening 12 can be positioned, which is convenient for realizing the quick, accurate, firm and reliable installation of the bracket.

[0052] In this embodiment, the connecting posts 14 protrude from the inner side surface of the folding edge 11. The connecting posts 14 can be cylindrical protrusions. A through hole with an open top is arranged in the connecting posts 14, and the through hole is arranged along the axial direction of the connecting posts 14. The connecting posts 14 correspond to the connecting holes 45, and a self-tapping screw is connected to the through hole of the connecting posts 14, so that the mounting plate 43 can be firmly connected to the connecting posts 14.

[0053] The installation groove includes a first installation groove 46 and a second installation groove 47. Specifically, a first installation groove 46 with an open top is arranged on the first mounting plate 41, and a second installation groove 47 is arranged through the bottom of the first installation groove 46; a PCB board 22 is installed in the first installation groove 46, the infrared sensor 20 is attached to the PCB board 22, and the infrared sensor 20 is inserted into the second installation groove 47.

[0054] In this embodiment, the first installation groove 46 is adapted to the shape of the first mounting plate 41, and the projection of the first installation groove 46 is also quadrilateral; the second installation groove 47 is integrally rectangular, and an anti-fooling rib 21 is arranged at the inner edge of one corner of the second installation groove 47.

[0055] By arranging the anti-fooling rib 21 in the second installation groove 47, the installation of the infrared sensor 20 can be positioned and anti-fooled, so that the infrared sensor 20 can only be installed in the second installation groove 47 in the orientation defined by the anti-fooling rib 21, which can enable the infrared sensor 20 to be quickly and accurately installed in the second installation groove 47, and can enable the probe on the infrared sensor 20 to just correspond to the transparent patch 31, so that the transparent patch 31 can avoid the probe on the infrared sensor 20, and the infrared rays emitted by the probe on the infrared sensor 20 can be effectively emitted to detect the crank, improving the effectiveness of detection.

[0056] The first installation groove 46 has an open top, and the cover plate 30 covers the open top of the first installation groove 46.

[0057] In this embodiment, the projection shape of the cover plate 30 is quadrilateral, and the cover plate 30 is adapted to the first support plate 41 and the first installation groove 46.

[0058] A stepped through hole 32 is provided inside the cover plate 30, and a stepped portion 33 is provided on the transparent patch 31, so that the transparent patch 31 can be adapted to the stepped through hole 32, enabling the transparent patch 31 to be conveniently, quickly, stably and reliably installed on the cover plate 30.

[0059] The transparent patch 31 can be adhesively fixed inside the cover plate 30 or fixed inside the cover plate 30 by other means, which is not specifically limited herein.

[0060] In this embodiment, the projection of the transparent patch 31 is circular. In other preferred embodiments, the transparent patch 31 can also be rectangular or of other shapes, which is not specifically limited herein.

[0061] An avoidance groove 34 is provided inside the cover plate 30. The avoidance groove 34 is adapted to the first installation groove 46, and the transparent patch 31 is arranged in the avoidance groove 34. By providing the avoidance groove 34, the distance between the transparent patch 31 and the infrared sensor 20 can be adjusted, preventing the transparent patch 31 from hindering the installation of the infrared sensor 20, enabling the transparent patch 31 to correspond to the probe 23 and having a certain distance therebetween, which can ensure the detection accuracy of the infrared sensor 20.

[0062] The distance between the transparent patch 31 and the probe 23 can be less than or equal to 0.5 mm. For example, it can be 0.5 mm, 0.45 mm, or 0.4 mm.

[0063] As Figure 11 shown, it is a front view of a partial structure of the trainer. The crank 100 is connected to the rotating shaft 101, and the rotation trajectory curve 102 of the crank 100 is circular. The infrared rays emitted by the infrared sensor 20 irradiate within the range defined by the rotation trajectory curve 102, enabling the detection of the crank 100.

[0064] The angle β1 is the included angle between the two extreme positions where the infrared rays can detect the crank 100. Beyond the range defined by the angle β1, the infrared rays cannot irradiate the crank 100. β1 does not exceed 130°. Preferably, β1 is 40° - 130°.

[0065] The angle β2 is the included angle between the two extreme positions where the infrared rays detect the rotating shaft 101. To ensure that the infrared rays can effectively detect the crank 100, the infrared rays should not irradiate within the range defined by the angle β2. The minimum value of β2 is 8°. Preferably, β1 is 8° - 30°.
