Description

Technical Field

[0001] The present application relates to the technical field of bicycle training wheel testing equipment, and in particular to a bicycle training wheel testing stand. Background Art

[0002] Bicycle training wheels are an integral part of the bicycle structure. In order to ensure that the bicycle can run smoothly and safely during riding, the quality inspection of the training wheels is particularly important.

[0003] At present, the traditional training wheel testing method mainly relies on manual visual inspection, which is to conduct an appearance inspection of the training wheel by observing its shape and whether there are bulges on the surface to judge its quality.

[0004] However, the visual inspection method is not only inefficient, but the test results are also greatly affected by human factors. In addition, it is not easy to detect the lateral stability problems of the training wheels through visual inspection, making it difficult to ensure the reliability of the test data.

[0005] In the above-mentioned related technologies, there is a defect that the reliability of the lateral stability test of the bicycle training wheels is not high. Utility Model Content

[0006] In order to improve the problem of low reliability in lateral stability testing of bicycle training wheels, the present application provides a bicycle training wheel test stand.

[0007] The bicycle training wheel test stand provided in this application adopts the following technical solutions:

[0008] A bicycle training wheel test stand comprises: a support mechanism, which supports the training wheel; a drive mechanism, which is connected to the support mechanism and is used to drive the training wheel to rotate; a first testing mechanism, which comprises two testing components, each of which comprises a rotating shaft and a first limiting member, the rotating shaft being connected to the support mechanism, a first end of the first limiting member being rotatably connected to the rotating shaft, an axis of the rotating shaft extending vertically, a second end of the first limiting member being used to abut against a side surface of the training wheel, two testing components being respectively arranged on either side of the training wheel, so that the two first limiting members respectively abut against the two sides of the training wheel; and a measuring mechanism, which is used to measure the horizontal distance between the second ends of the two first limiting members.

[0009] By adopting the above technical solution, the support mechanism can keep the training wheel stable during the test, avoiding lateral shaking or deviation caused by external factors; the driving mechanism is used to drive the training wheel to rotate, thereby simulating the motion state in an actual use environment and improving the authenticity and reliability of the test; the two test components of the first testing mechanism are respectively arranged on both sides of the training wheel, the rotating shaft is connected to the support mechanism, the first end of the first limiter is rotatably connected to the rotating shaft, and the second end of the first limiter abuts the side of the training wheel, so that the training wheel can pass between the two first limiters when rotating; because the first limiter abuts the side of the training wheel, when a bulge appears on the side of the training wheel, it will push the second end of the first limiter to rotate about the rotating shaft, thereby changing the distance between the second ends of the two first limiters. The measuring mechanism can accurately measure the horizontal spacing between the second ends of the two first limiters, thereby providing accurate and reliable test data, and then evaluating the degree of lateral deformation of the training wheel, thereby improving the reliability of the test of bicycle training wheels.

[0010] Optionally, the rotating shaft is a damping rotating shaft.

[0011] By adopting the above technical solution, the damping shaft can reduce the freedom of movement of the first limit member, so that the first limit member can stably abut the side of the auxiliary wheel according to the width of the auxiliary wheel; and, in the case where there is a protrusion on the side of the auxiliary wheel, the damping shaft can prevent the second end of the first limit member from moving arbitrarily after rotation, thereby improving the measurement accuracy of the measuring mechanism and further enhancing the reliability of the test.

[0012] Optionally, arc structures are provided at both the upper and lower ends of the first limiting member.

[0013] By adopting the above technical solution, the arc structures provided at the upper and lower ends of the first limiter can effectively reduce the risk of the auxiliary wheel getting stuck when the protrusion contacts the first limiter when the auxiliary wheel rotates, thereby improving the reliability of the auxiliary wheel rotation during the test.

[0015] By adopting the above technical solution, the auxiliary wheel can always abut against one side of the second limit member during the rotation process; when a protrusion appears on the outer circumference of the auxiliary wheel, the protrusion will push the second limit member to slide on the supporting member, so that the second limit member is away from the auxiliary wheel, thereby enabling the testing of the outer circumference of the auxiliary wheel; at the same time, the supporting member is arranged below the horizontal plane where the center of the auxiliary wheel is located, which helps to reduce the risk of interference between the supporting member and the auxiliary wheel.

[0016] Optionally, a spherical surface is provided on a side of the second limiting member close to the auxiliary wheel, and the spherical surface protrudes toward the side close to the auxiliary wheel.

[0017] By adopting the above technical solution, a spherical surface is provided on the side of the second limit member close to the auxiliary wheel, which can effectively reduce the friction when the second limit member contacts the auxiliary wheel, thereby improving the smoothness and accuracy of the test process; at the same time, the spherical surface design can also reduce the risk of the rotating auxiliary wheel getting stuck with the upper or lower end of the second limit member when contacting the second limit member, thereby ensuring the reliable conduct of the test.

[0018] Optionally, the second testing mechanism includes an adjustment assembly, which includes an adjustment bracket, a lead screw and a nut. The support mechanism is provided with a sliding hole, the bearing member is slidably connected to the sliding hole, the adjustment bracket is connected to the support mechanism, one end of the lead screw is rotatably connected to the adjustment bracket, and the other end of the lead screw is rotatably connected to the support mechanism. The nut is threadedly connected to the lead screw, the nut and the adjustment bracket are slidably matched, and the bearing member is connected to the nut, so that the bearing member moves horizontally with the nut.

[0019] By adopting the above technical solution, the setting of the adjustment component enables the carrier to move horizontally in the sliding hole, and the carrier is connected to the nut, so that the rotation of the screw can drive the nut to move linearly, thereby enabling the carrier to move horizontally, thereby achieving precise adjustment of the position of the second test mechanism, ensuring that the second limit member can contact the auxiliary wheel, and improving the reliability of the test results.

[0020] Optionally, the driving mechanism is arranged above the auxiliary wheel, and the driving mechanism includes a belt member and a driving assembly. The driving assembly is connected to the supporting mechanism, the belt member is transmission-connected to the driving assembly, and the lower side of the belt member is used to drive the auxiliary wheel to rotate.

[0021] By adopting the above technical solution, the driving mechanism is arranged above the auxiliary wheel, which can effectively utilize the space and avoid interference with other components; the driving component of the driving mechanism drives the belt member to rotate, and the lower side of the belt member drives the auxiliary wheel to rotate through friction, which can make the auxiliary wheel rotate smoothly and improve the reliability of the test.

[0022] Optionally, the drive assembly includes a drive motor and two pulleys, the drive motor and the pulleys are both connected to the support mechanism, the output end of the drive motor is connected to the pulleys for transmission, the belt member is wrapped around the outer circumference of the two pulleys, and the drive motor drives the belt member to rotate through the pulleys, so that the belt member can drive the auxiliary wheel to rotate.

[0023] By adopting the above technical solution, the combination of the drive motor and the pulley can achieve efficient and stable power transmission, ensuring that the belt member smoothly drives the auxiliary wheel to rotate, thereby improving the power transmission efficiency and stability of the test frame; at the same time, the drive motor drives the belt member to rotate through the pulley, making the rotation of the auxiliary wheel more stable, reducing test errors caused by unstable power transmission, and improving the accuracy of test results.

[0024] Optionally, the support mechanism includes a support plate and two telescopic parts, the fixed end of the telescopic part is connected to the support plate, the telescopic end of the telescopic part is telescopic in the vertical direction, the telescopic end of the telescopic part is used to set up the central axis of the auxiliary wheel, and the two telescopic parts are respectively arranged on both sides of the auxiliary wheel, so that the auxiliary wheel can rotate around the central axis.

[0025] By adopting the above technical solution, the support plate provides reliable support for the telescopic parts. The two telescopic parts are respectively arranged on both sides of the auxiliary wheel, which helps to improve the support stability of the central axis of the auxiliary wheel; the vertical extension and retraction of the telescopic parts can facilitate the replacement and height adjustment of the auxiliary wheel, thereby improving the convenience of testing.

[0026] Optionally, the supporting mechanism includes a supporting member, which is provided at the telescopic end of the telescopic member, and is used to support the central axis so that the central axis can rotate on the supporting member.

[0027] By adopting the above technical solution, the supporting member in the support mechanism can stably support the central axis of the auxiliary wheel, so that the auxiliary wheel can rotate smoothly during the test, reducing the test error caused by the instability of the central axis; at the same time, the design of the supporting member enables the central axis of the auxiliary wheel to rotate freely on the supporting member, thereby improving the accuracy and reliability of the test.

[0036] The following is combined with Figure 1 and attached Figure 2 The present application will be further described in detail. In this embodiment, unless otherwise specified, the terms "connected", "connected" and "fixed" are understood in a broad sense, including fixed connection, detachable connection, connection to form an integral structure, mechanical connection, electrical connection, direct connection, indirect connection through an intermediary, internal connection and interaction between two elements, and can be understood based on the specific circumstances.

[0037] In this application, unless otherwise expressly specified and limited, a first feature being "above" or "below" a second feature may include the first and second features being in direct contact, or the first and second features being in contact not directly but through another feature between them. Moreover, in the description of this embodiment, the terms "above", "below", "right", and other orientations or positional relationships are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on this application. Unless otherwise specified, orientation words such as "inside" and "outside" used in this application refer to the outlines of the corresponding components themselves.

[0038] like Figure 1As shown, an embodiment of the present application discloses a bicycle training wheel test stand (hereinafter referred to as a “test stand”), which includes a support mechanism 1, a drive mechanism 2, a first test mechanism 3 and a measuring mechanism.

[0039] Support mechanism 1 supports auxiliary wheels 100, ensuring stability during testing and preventing lateral movement or deviation due to external factors. Drive mechanism 2 is connected to support mechanism 1 and is used to rotate auxiliary wheels 100, thereby simulating the motion conditions found in actual use and improving the authenticity and reliability of the test.

[0040] like Figure 1 and Figure 2 As shown, the first testing mechanism 3 includes two testing assemblies, each comprising a rotating shaft 31 and a first stopper 32. The rotating shaft 31 is connected to the support mechanism 1, and its axis extends vertically. The first end of the first stopper 32 is rotatably connected to the rotating shaft 31, and the second end of the first stopper 32 is used to abut the side of the auxiliary wheel 100. The two testing assemblies are respectively arranged on either side of the auxiliary wheel 100, so that the two first stoppers 32 abut the two sides of the auxiliary wheel 100, allowing the auxiliary wheel 100 to pass between the two first stoppers 32 during rotation. The width of the auxiliary wheel 100 can be determined by the horizontal distance between the second ends of the two first stoppers 32. By measuring whether the width of the auxiliary wheel 100 has changed, the lateral stability data of the auxiliary wheel 100 can be obtained.

[0041] The measuring mechanism is used to measure the horizontal spacing between the second ends of the two first stoppers 32. Because the first stoppers 32 abut the side of the training wheel 100, a bulge on the side of the training wheel 100 pushes the second ends of the first stoppers 32 to rotate horizontally about the rotation axis 31, thereby changing the horizontal distance between the second ends of the two first stoppers 32. The measuring mechanism can accurately measure the horizontal spacing between the second ends of the two first stoppers 32 before and after the training wheel 100 rotates, thereby providing accurate and reliable test data, thereby assessing the degree of lateral deformation of the training wheel 100 and improving the reliability of testing of bicycle training wheels 100. The measuring mechanism can be a ruler.

[0042] like Figure 1 and Figure 2As shown, optionally, the support mechanism 1 includes a support plate 12 and two telescopic parts 13. The support plate 12 serves as a base for the test stand, the fixed end of the telescopic part 13 is connected to the support plate 12, and the telescopic end of the telescopic part 13 telescopes in the vertical direction. The telescopic end of the telescopic part 13 is used to set up the central axis 110 of the auxiliary wheel 100, and the two telescopic parts 13 are respectively arranged on both sides of the auxiliary wheel 100, so that the auxiliary wheel 100 can rotate around the central axis 110. The support plate 12 provides reliable support for the telescopic part 13, and the two telescopic parts 13 are respectively arranged on both sides of the auxiliary wheel 100, which helps to improve the support stability of the central axis 110 of the auxiliary wheel 100. The vertical extension and retraction of the telescopic part 13 can facilitate the replacement and height adjustment of the auxiliary wheel 100, thereby improving the convenience of testing.

[0043] Optionally, the support mechanism 1 includes a supporting member 14. The supporting member 14 is disposed at the telescopic end of the telescopic member 13 and is used to support the central axis 110 so that the central axis 110 can rotate on the supporting member 14. The supporting member 14 in the support mechanism 1 can stably support the central axis 110 of the auxiliary wheel 100, allowing the auxiliary wheel 100 to rotate smoothly during the test, thereby reducing test errors caused by the instability of the central axis 110. At the same time, the design of the supporting member 14 allows the central axis 110 of the auxiliary wheel 100 to rotate freely on the supporting member 14, thereby improving the accuracy and reliability of the test. The support member 14 may have a U-shaped groove structure to reliably support the central axis 110 of the auxiliary wheel 100. The support member 14 may also include a bearing and a bearing seat. The bearing seat is located at the telescopic end of the telescopic member 13, and the bearing is sleeved around the outer periphery of the central axis 110 of the auxiliary wheel 100. The bearing and the bearing seat cooperate to reduce the rotational resistance of the auxiliary wheel 100. The support member 14 may also have other structures that can support the central axis 110 and enable the central axis 110 to rotate relative to the support member 14. The spacing between the two telescopic members 13 is set as needed, and the horizontal length of the support member 14 along the axis of the central axis 110 is set as needed to enable the central axis 110 to be supported on the support member 14.

[0044] like Figure 1 and Figure 2 As shown, optionally, the drive mechanism 2 is arranged above the auxiliary wheel 100, which can effectively utilize space and avoid interference with other components. The drive mechanism 2 includes a belt member 21 and a drive assembly 22. The drive assembly 22 is connected to the support mechanism 1. The belt member 21 is connected to the drive assembly 22 through transmission. The lower side of the belt member 21 is used to drive the auxiliary wheel 100 to rotate. The drive assembly 22 of the drive mechanism 2 drives the belt member 21 to rotate. The lower side of the belt member 21 drives the auxiliary wheel 100 to rotate through friction, which can make the auxiliary wheel 100 rotate smoothly and improve the reliability of the test. The telescopic member 13 can be a structure that can achieve telescopic movement, such as a cylinder, a hydraulic cylinder, or an electric telescopic rod.

[0045] like Figure 1 and Figure 2 As shown, optionally, the drive assembly 22 includes a drive motor 221 and two pulleys 222. The drive motor 221 is connected to the support mechanism 1, and the pulleys 222 are rotatably connected to the support mechanism 1. The output end of the drive motor 221 is connected to the pulleys 222, and the belt member 21 is wound around the outer circumference of the two pulleys 222. The drive motor 221 can drive the belt member 21 to rotate through the pulleys 222, so that the belt member 21 can drive the auxiliary wheel 100 to rotate. The combination of the drive motor 221 and the pulleys 222 can achieve efficient and stable power transmission, ensuring that the belt member 21 can smoothly drive the auxiliary wheel 100 to rotate, thereby improving the power transmission efficiency and stability of the test stand. At the same time, the drive motor 221 drives the belt member 21 to rotate through the pulleys 222, making the rotation of the auxiliary wheel 100 more stable, reducing test errors caused by unstable power transmission, and improving the accuracy of the test results. The setting of the drive mechanism 2 enables the auxiliary wheel 100 to be driven to rotate, simulating the dynamic conditions in actual use, improving the authenticity and reliability of the test, and reducing the limitations of traditional static test methods.

[0046] Optionally, the rotating shaft 31 is a damping rotating shaft. This damping rotating shaft reduces the freedom of movement of the first stopper 32, allowing the first stopper 32 to stably abut the side of the auxiliary wheel 100 according to the width of the auxiliary wheel 100. Furthermore, if there is a protrusion on the side of the auxiliary wheel 100, the damping rotating shaft prevents the second end of the first stopper 32 from moving freely after rotation, thereby improving the measurement accuracy of the measuring mechanism and, in turn, the reliability of the test. The damping rotating shaft 31 can be selected from an existing structure based on actual conditions to meet the needs of use, so that the first stopper 32 only rotates when subjected to external force.

[0047] like Figure 1 and Figure 2 As shown, optionally, arc structures 321 are provided at both the upper and lower ends of the first limit member 32, which effectively reduces the risk of the auxiliary wheel 100 getting stuck when the protrusion on the side of the auxiliary wheel 100 contacts the first limit member 32 when the auxiliary wheel 100 rotates, thereby improving the reliability of the rotation of the auxiliary wheel 100 during the test.

[0048] Optionally, the test stand also includes a second test mechanism 4, so that the auxiliary wheel 100 can be horizontally mounted between the first test mechanism 3 and the second test mechanism 4. The second test mechanism 4 includes a bearing member 41 and a second limiting member 42. One end of the bearing member 41 is connected to the support mechanism 1, and the bearing member 41 is arranged below the horizontal plane where the center of the auxiliary wheel 100 is located. The bearing member 41 and the outer peripheral surface of the auxiliary wheel 100 are arranged horizontally at intervals, which helps to reduce the risk of interference between the bearing member 41 and the auxiliary wheel 100. The second limiting member 42 is slidably connected to the bearing member 41, and the side of the second limiting member 42 close to the auxiliary wheel 100 is used to abut the auxiliary wheel 100, so that the auxiliary wheel 100 can push the second limiting member 42 to slide on the bearing member 41. The auxiliary wheel 100 can always abut against one side of the second limit member 42 during the rotation process; when a protrusion appears on the outer circumference of the auxiliary wheel 100, the protrusion will push the second limit member 42 to slide on the supporting member 41, causing the second limit member 42 to move away from the auxiliary wheel 100, so that the relative position of the second limit member 42 and the supporting member 41 can be changed to determine whether there is a protrusion on the outer circumference of the auxiliary wheel 100, thereby realizing the test of the outer circumference of the auxiliary wheel 100.

[0049] like Figure 1 and Figure 2 As shown, the second stopper 42 can optionally be provided with a spherical surface 421 on the side closest to the auxiliary wheel 100. This spherical surface 421 protrudes toward the side closest to the auxiliary wheel 100, thereby reducing friction when the second stopper 42 contacts the auxiliary wheel 100 and improving smoothness and accuracy during testing. Furthermore, the spherical surface 421 design also reduces the risk of the rotating auxiliary wheel 100 becoming stuck with the upper or lower end of the second stopper 42 when contacting it, ensuring reliable testing.

[0050] like Figure 1 and Figure 2As shown, optionally, the second testing mechanism 4 includes an adjustment assembly 43, which is arranged below the supporting member 41. The adjustment assembly 43 includes an adjustment bracket 431, a lead screw 432 and a nut 433. The support mechanism 1 includes a support side plate 15, a sliding hole 11 is opened on the support side plate 15, and the sliding hole 11 horizontally passes through the support side plate 15, and the supporting member 41 is slidably connected to the sliding hole 11. The adjustment bracket 431 is connected to the support mechanism 1, one end of the lead screw 432 is rotatably connected to the adjustment bracket 431, and the other end of the lead screw 432 is rotatably connected to the support mechanism 1, and the nut 433 is screwed to the lead screw 432. The nut 433 slides with the adjustment bracket 431 to limit the rotation of the nut 433. The support member 41 is connected to the nut 433, allowing the support member 41 to move horizontally and linearly along the screw 432 with the nut 433, thereby enabling the support member 41 to move toward or away from the auxiliary wheel 100, facilitating contact between the spherical surface 421 above the support member 41 and the outer circumference of the auxiliary wheel 100. A handle 434 can be provided at the end of the screw 432 away from the auxiliary wheel 100. The handle 434 is located on the side of the support side plate 15 away from the auxiliary wheel 100. The screw 432 can be rotated manually by turning the handle 434. The configuration of the adjustment assembly 43 enables the support member 41 to move horizontally within the slide hole 11. The support member 41 is connected to the nut 433, so that rotation of the screw 432 drives linear movement of the nut 433, thereby enabling horizontal movement of the support member 41, achieving precise adjustment of the position of the second testing mechanism 4, ensuring that the second limit member 42 can contact and abut the auxiliary wheel 100, and improving the reliability of the test results. The first limiting member 32 , the second limiting member 42 and the supporting member 41 may all be plate-shaped structures; the supporting member 41 is provided with a sliding groove, and the lower end of the second limiting member 42 is provided with a slider, which is slidably connected to the sliding groove.

[0051] When testing the auxiliary wheel 100, this test stand can test the same auxiliary wheel 100 multiple times, with the initial circumferential position of the auxiliary wheel 100 being different before each test. This means that the initial contact positions of the first stopper 32 and the second stopper 42 on the auxiliary wheel 100 are different, reducing the risk of a protrusion at the initial contact position affecting the test structure. The test stand in this embodiment is used to test auxiliary wheels 100 of fixed sizes from the same batch. In other embodiments, the vertical heights of the first and second test mechanisms 3 and 4, as well as the dimensions and positions of their respective components, can be adjusted to allow testing of auxiliary wheels 100 of varying diameters, as required. It is understood that the test stand also includes the necessary structures for connection, support, drive, positioning, limiting, and control functions to ensure proper operation. Parameters such as the shape, size, material, and number of components of the test stand can be determined as needed to achieve the corresponding functions.

[0052] The working principle of a bicycle training wheel test stand according to the embodiment of the present application is as follows: a driving mechanism 2 drives the training wheel 100 to rotate, simulating the motion state under actual use conditions. Two test assemblies of a first testing mechanism 3 are respectively arranged on either side of the training wheel 100. The rotating shaft 31 of the test assembly is connected to the support mechanism 1. The first end of a first stopper 32 is rotatably connected to the rotating shaft 31, and the second end of the first stopper 32 abuts the side of the training wheel 100, so that the training wheel 100 can pass between the two first stoppers 32 during rotation. When a bulge appears on the side of the training wheel 100, it pushes the second end of the first stopper 32 to rotate horizontally about the rotating shaft 31, causing the distance between the second ends of the two first stoppers 32 to change. Before and after the training wheel 100 rotates, a measuring mechanism measures the horizontal distance between the second ends of the two first stoppers 32. The difference in the measured data on both sides is used to determine the degree of deformation of the side surface of the training wheel 100. This improves the reliability of the lateral stability test of the bicycle training wheel 100 through mechanical structure measurement.

[0053] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
