Thus, the features defined with "first" and "second" may explicitly or implicitly include at least one of such features. In the description of the present invention, the meaning of "plurality" is at least two, such as two, three, etc., unless otherwise specifically and clearly defined.

[0043] In the present invention, unless otherwise clearly specified or defined, the terms "mounted", "connected", "coupled", "fixed", etc. shall be construed in a broad sense. For example, it may be a fixed connection, a detachable connection, or an integral one; it may be a mechanical connection or an electrical connection; it may be directly connected or indirectly connected through an intermediate medium, and it may be the communication inside two elements or the interaction relationship between two elements, unless otherwise clearly defined.

The terms "vertical", "horizontal", "up", "down", "left", "right" and similar expressions used herein are only for the purpose of illustration and do not represent the only implementation.

[0046] Referring to Figure 1 and Figure 2 , an embodiment of the present application provides a riding test bench 100. The riding test bench 100 includes a base 10, a rear support frame 20 and a fixing mechanism 30. The rear support frame 20 is swingably mounted on the base 10 around a first axis extending along a first direction X, and the rear support frame 20 is used to support the rear wheel 202 of the bicycle 200. The fixing mechanism 30 is connected to the rear support frame 20, and the fixing mechanism 30 is used to fix the bicycle 200 to the rear support frame 20. Here, it should be noted that the fixing mechanism 30 fixing the bicycle 200 to the rear support frame 20 means that the fixing mechanism 30 can keep the frame 204 of the bicycle 200 fixed to the rear support frame 20, while the rear wheel 202 of the bicycle 200 can rotate on the rear support frame 20, so as to facilitate the riding training of the rider.

[0047] Continuing to refer to Figure 2, the riding test bench 100 further includes a detection mechanism 40 and a driving mechanism 50. The detection mechanism 40 is used to obtain riding data, and the driving mechanism 50 is connected to the rear support frame 20. That is, when a rider rides a bicycle 200 fixed to the rear support frame 20, the detection mechanism 40 can obtain riding data. The driving mechanism 50 is used to drive the rear support frame 20 to swing relative to the base 10 around the first axis when the riding data meets the pedaling condition, so that the bicycle 200 sways left and right. That is, whether the driving mechanism 50 drives the rear support frame 20 to rotate relative to the base 10 is based on the riding data as a precondition. When the riding data meets the pedaling condition, the driving mechanism 50 will drive the rear support frame 20 to swing relative to the base 10, thereby driving the bicycle 200 supported on the rear support frame 20 to swing left and right synchronously.

[0048] It should be noted here that the left, right, front, rear, up, and down mentioned in the text are all based on the perspective of the rider when the rider rides a bicycle 200 supported on the rear support frame 20. The front and rear of the rider are the front and rear directions, the left and right of the rider are the left and right directions, and the up and down of the rider are the up and down directions.

[0049] Optionally, when the base 10 is supported on a plane, the first direction X is parallel or substantially parallel to the front and rear directions.

[0050] In the riding test bench 100 provided by the embodiment of the present application, the detection mechanism 40 obtains riding data, and the driving mechanism 50 is used to drive the rear support frame 20 to swing relative to the base 10 around the first axis when the riding data meets the pedaling condition, so that the bicycle 200 sways left and right, that is, to realize the pedaling action. In this way, it can more realistically simulate riding. Even for riders who cannot complete the pedaling action by themselves, they can also experience pedaling, improving the riding experience of the riders. And, the fixing mechanism 30 can fix the bicycle to the support frame 20, and the support frame 20 drives the bicycle 200 to swing relative to the base 10 around the first axis to realize the pedaling action, ensuring that the bicycle is firmly fixed during pedaling and improving the safety of pedaling.

[0051] In some embodiments, the riding test bench 100 further includes a controller (not shown in the figure), and both the detection mechanism 40 and the driving mechanism 50 are electrically connected to the controller. The controller can obtain the riding data detected by the detection mechanism 40 and control the action of the driving mechanism 50 according to the riding data. Specifically, when the controller determines that the riding data meets the pedaling action, it controls the driving mechanism 50 to act.

[0052] Continue to refer to Figure 1 , the riding test bench 100 further includes a bearing seat 60 and a bearing. The bearing seat 60 is installed on the base 10, the bearing is installed on the bearing seat 60, and the rear support frame 20 is connected to the bearing. The rear support frame 20 is rotationally connected to the base 10 through the bearing around the first axis.

[0053] Optionally, in the first direction X, a bearing seat 60 is provided at both ends of the base 10, and both ends of the rear support frame 20 are respectively mounted on the two bearing seats 60 through bearings. In this way, the rear support frame 20 is rotationally connected to the base 10 through two bearings, which not only ensures the support effect of the rear support frame 20 on the rear wheel 202 of the bicycle 200, but also ensures the smooth performance when the rear support frame 20 rotates relative to the base 10.

[0054] In some embodiments, referring to Figure 3 , the rear support frame 20 includes a main body frame 21 and two extension arms 22. The two extension arms 22 are respectively connected to the tops of both ends of the main body frame 21 in the second direction Y, and the main body frame 21 is used to support the rear wheel 202 of the bicycle 200. There are two fixing mechanisms 30, and the two fixing mechanisms 30 are respectively connected to the two extension arms 22, and the two fixing mechanisms 30 are respectively fixedly connected to both ends of the frame 204 in the second direction Y. Among them, the first direction X and the second direction Y intersect. Specifically, the first direction X and the second direction Y are perpendicular. In some specific embodiments, the second direction Y is the above-mentioned left-right direction. Optionally, the rear support frame 20 is of a cradle type structure.

[0055] Further, referring to Figure 4 , the fixing mechanism 30 includes a sleeve 31, and the sleeve 31 is used to be inserted into the rear fork assembly 206 of the bicycle 200 to realize the fixed connection between the rear support frame 20 and the frame 204.

[0056] It can be imagined that in some other embodiments, the fixing mechanism 30 can also adopt other settings. For example, the fixing mechanism 30 is provided to include fixing screws, and the fixing screws pass through the rear support frame 20 and the frame 204 to realize the fixed connection between the frame 204 and the rear support frame 20. The specific setting of the fixing mechanism 30 is selected according to needs and is not limited herein.

[0057] In some embodiments, continuing to refer to Figure 4 , the riding test bench 100 further includes a damper 80, and the damper 80 is installed on the rear support frame 20. The damper 80 cooperates with the rear support frame 20 to support the rear wheel 202 of the bicycle 200. The damper 80 can apply different damping values to the rear wheel 202 of the bicycle 200 to achieve different training effects.

[0058] Further, the riding test bench 100 further includes a power meter, and the power meter is used to detect the pedal power and / or the chainring power as the input power, and the damper 80 is used to contact the rear wheel 202 to detect the output power of the bicycle 200. The controller calculates the ratio of the output power to the input power to obtain the transmission efficiency, and the transmission efficiency can be displayed on an external display, and the advantages and disadvantages of different bicycle performances can be compared through the transmission efficiency.

[0059] Optionally, the above power meter includes a pedal power meter for testing pedal power and a chainring power meter for testing chainring power. At this time, it is possible to simultaneously test the pedal power and the chainring power, and the transmission efficiency can be obtained by calculating the ratios of the output power to the pedal power and the output power to the chainring power, enabling a more comprehensive comparison of the performance of the bicycle.

[0060] Of course, in some other embodiments, the above power meter may also include only a pedal power meter or only a chainring power meter, which is not limited herein.

[0061] In some embodiments, referring to Figure 4 and Figure 5 , the detection mechanism 40 includes a first sensor 41 and two second sensors 42 both mounted on the rear support frame 20. The first sensor 41 is used to detect the rotational speed of the rear wheel 202 of the bicycle 200, and one second sensor 42 is used to detect the left foot of the rider and / or the left pedal of the bicycle 200, and the other second sensor 42 is used to detect the right foot of the rider and / or the right pedal of the bicycle 200.

[0062] When the first sensor 41 detects that the rotational speed of the rear wheel 202 is greater than a preset threshold and the second sensor 42 detects the left foot and / or the left pedal, the driving mechanism 50 drives the rear support frame 20 to swing leftward relative to the base 10; when the first sensor 41 detects that the rotational speed of the rear wheel 202 is greater than a preset threshold and the second sensor 42 detects the right foot and / or the right pedal, the driving mechanism 50 drives the rear support frame 20 to swing rightward relative to the base 10. That is, the condition for rocking the bicycle to the left is that the rotational speed of the rear wheel 202 is greater than a preset threshold and the left foot is exerting force. The condition for rocking the bicycle to the right is that the rotational speed of the rear wheel 202 is greater than a preset threshold and the right foot is exerting force.

[0063] With the above settings, the first sensor 41 detects the rotational speed of the rear wheel 202. When the rotational speed of the rear wheel 202 is greater than a preset threshold, it proves that the rider is riding the bicycle 200 at a relatively high speed and is suitable for rocking the bicycle. When the left second sensor 42 detects the left foot and / or the left pedal, it proves that the rider's left foot is exerting force, and then the bicycle can be rocked to the left. At this time, the controller controls the driving mechanism 50 to drive the rear support frame 20 to rotate leftward about the first axis relative to the base 10, causing the bicycle 200 to swing leftward. When the right second sensor 42 detects the right foot and / or the right pedal, it proves that the rider's right foot is exerting force, and then the bicycle can be rocked to the right. At this time, the controller controls the driving mechanism 50 to drive the rear support frame 20 to rotate rightward about the first axis relative to the base 10, causing the bicycle 200 to swing rightward.

[0064] It can be conceived that in some other embodiments, the detection mechanism 40 can also be arranged in other ways, as long as it has the function of detecting riding data, which is not limited herein.

[0065] In some embodiments, referring to Figure 6 , the drive mechanism 50 includes a drive member 51, a lead screw 52, and a nut assembly 53. The lead screw 52 and the drive member 51 are both mounted on the base 10. The lead screw 52 is connected to the drive member 51. The nut assembly 53 is screwed onto the lead screw 52 and is movably connected to the rear support frame 20. The drive member 51 drives the lead screw 52 to rotate about a second axis extending along the second direction Y, so as to drive the nut assembly 53 to move along the second direction Y, and further drive the rear support frame 20 to swing about the first axis.

[0066] With the above arrangement, when the controller determines that the riding data meets the condition for rocking the bike, the controller controls the drive member 51 to act. The drive member 51 drives the lead screw 52 to rotate about the second axis, and the nut assembly 53 moves along the second direction Y. Since the nut assembly 53 is movably connected to the rear support frame 20, when the nut assembly 53 moves along the second direction Y, it can drive the rear support frame 20 to swing about the first axis, thereby driving the bicycle 200 to rock.

[0067] Furthermore, the drive mechanism 50 further includes a transmission assembly 54, and the transmission assembly 54 is disposed between the drive member 51 and the lead screw 52. Optionally, the transmission assembly 54 includes a pulley and a transmission belt. One pulley is connected to the drive member 51, the other pulley is connected to the lead screw 52, and the transmission belt is sleeved outside the two pulleys. The drive member 51 drives the pulley connected thereto to rotate, the transmission belt moves, and drives the lead screw 52 to rotate through the other pulley. Of course, in some other embodiments, the transmission assembly 54 of the drive mechanism 50 may also be omitted, or the transmission assembly 54 may also be arranged in other ways, such as gear transmission, etc.

[0068] In some embodiments, referring to Figure 6 and Figure 7 , a kidney-shaped hole 90 extending along the third direction Z is provided on one of the rear support frame 20 and the nut assembly 53, and the other is movably disposed in the kidney-shaped hole 90 along the third direction Z. Among them, the first direction X, the second direction Y, and the third direction Z intersect pairwise. Specifically, the first direction X, the second direction Y, and the third direction Z are perpendicular to each other pairwise. Optionally, the third direction Z is the up-down direction.

[0069] With the above arrangement, when the lead screw 52 drives the nut assembly 53 to move along the second direction Y, due to the provision of the kidney-shaped hole 90, the nut assembly 53 also moves relative to the rear support frame 20 along the third direction Z. In this way, when the nut assembly 53 moves along the second direction Y, a force can be applied to the rear support frame 20, causing the rear support frame 20 to swing about the first axis.

[0070] The above drive member 51 can be selected as a motor or a cylinder, etc.

[0071] It is conceivable that in some other embodiments, the specific arrangement of the driving mechanism 50 is not limited herein, as long as it can drive the rear support frame 20 to swing around the first axis.

[0072] In some embodiments, with continued reference to Figure 3 and Figure 4 , the riding test bench 100 further includes a front support frame 110. The front support frame 110 is connected to the base 10 and is used to support the front wheel 201 of the bicycle 200. In this way, when the bicycle 200 is placed on the riding test bench 100, the rear wheel 202 and the front wheel 201 of the bicycle 200 are respectively supported by the rear support frame 20 and the front support frame 110, so as to ensure a better riding training effect.

[0073] Furthermore, the front support frame 110 includes a chassis 101 and a support platform 102. The chassis 101 is connected to the base 10, and the support platform 102 is arranged on the chassis 101 to support the front wheel 201 of the bicycle 200. Such an arrangement facilitates the connection between the front support frame 110 and the base 10 and at the same time facilitates the support of the front wheel 201 of the bicycle 200.

[0074] Even further, the support platform 102 is rotatably arranged on the chassis 101 around a third axis extending along the third direction Z. Since the handlebar assembly 203 of the bicycle 200 is connected to the front fork assembly 205, and the front fork assembly 205 is used to mount the front wheel 201. When the handlebar assembly 203 is rotated, the front wheel 201 will be driven to rotate through the front fork assembly 205. By setting the support platform 102 to be able to rotate around the third axis, when the front wheel 201 rotates driven by the handlebar assembly 203, the support platform 102 can rotate synchronously, ensuring a better riding effect.

[0075] Optionally, a limiting groove 1021 is provided on the support platform 102, and the front wheel 201 is limited to the limiting groove 1021. In this way, when the front wheel 201 rotates, since the front wheel 201 is limited to the limiting groove 1021, the support platform 102 can be driven to rotate synchronously.

[0076] In some embodiments, the support platform 102 is arranged on the chassis 101 with adjustable position along the first direction X. In this way, it is convenient to adjust the distance between the support platform 102 and the rear support frame 20 to adapt to bicycles 200 of different models.

[0077] Optionally, with continued reference to Figure 3, the chassis 101 includes a sliding rod 1011 extending along the first direction X. The support platform 102 is provided with a chute, and the sliding rod 1011 is received in the chute. The support platform 102 slides relative to the sliding rod 1011 along the first direction X through the chute to adjust the position of the support platform 102 on the chassis 101. The front support frame 110 further includes a fixing member. After the position of the support platform 102 is adjusted, the fixing member fixes the support platform 102 on the sliding rod 1011.

[0078] It is conceivable that in some other embodiments, other ways may also be adopted to adjust the position of the support platform 102 along the first direction X relative to the chassis 101, which is not limited herein.

[0079] The technical features of the above-described embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope described in this specification.

[0080] The above-described embodiments only represent several implementation manners of the present invention. The description is relatively specific and detailed, but it should not be construed as a limitation on the scope of the invention patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several modifications and improvements can still be made, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention patent shall be subject to the appended claims.
