It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

[0032] like Figure 1As shown, this embodiment provides a handlebar grip connection strength testing device for detecting the connection strength between the grip 200 fitted on the handlebar 100 and the handlebar 100. The handlebar grip connection strength testing device includes a pull-out mechanism 1, an environmental test chamber 2, and a water immersion mechanism. The pull-out mechanism 1 includes a handlebar clamp 11, a grip 200 clamp 12, and a pull-out assembly 13. The handlebar clamp 11 is used to hold the handlebar 100, the grip 200 clamp is used to fix it to the grip 200, and the pull-out assembly 13 can be connected to the grip 200 clamp 12 to apply a pulling force away from the handlebar 100 to the grip 200. The environmental test chamber 2 is used to house the pull-out mechanism 1 and the handlebar 100 fitted with the grip 200. The environmental test chamber 2 can adjust its internal temperature and the rate of temperature change. The water immersion mechanism is located inside the environmental test chamber 2 to place the handlebar 100 and the grip 200 in a water immersion environment.

[0033] During testing, the handlebar 100 with the handlebar grip 200 attached is first clamped onto the handlebar clamp 11, and the pulling assembly 13 is connected to the handlebar grip 200 via the handlebar grip clamp 12. Then, the connected handlebar 100, handlebar grip 200, and pulling mechanism 1 are placed in an environmental test chamber 2, and the immersion mechanism is activated to place the handlebar 100 and handlebar grip 200 in a water immersion environment. The temperature and rate of temperature change within the environmental test chamber 2 are adjusted to simulate a temperature change environment. Simultaneously with the temperature change, a pulling force away from the handlebar 100 is applied to the handlebar grip 200 via the pulling assembly 13, and the test is performed. Whether the grip 200 shifts relative to the handlebar 100 can determine whether the connection strength between the handlebar 100 and the grip 200 is up to standard under temperature changes and immersion conditions, which helps ensure riding safety. Furthermore, by testing the connection strength between the handlebar 100 and the grip 200 using the aforementioned testing device, and comparing the connection strength between the grip 200 and the handlebar 100 with variables such as material, structure, temperature, and temperature change rate, it is possible to develop grips 200 and handlebar 100 with higher connection strength for different usage scenarios, which helps to promote industry progress.

[0034] Continue as Figure 1 As shown, specifically, the immersion mechanism includes a nozzle 3, which sprays water onto the handlebars 100 and grips 200 to simulate the application scenario where rainwater may seep into the gap between the handlebars 100 and grips 200 during outdoor rainy weather. Testers can adjust the water spray volume according to experimental needs to test the connection strength between the handlebars 100 and grips 200 under extreme weather conditions, meeting various testing requirements. Furthermore, the handlebar / grip connection strength testing device also includes a water pump 4 and a water tank 5. The inlet of the water pump 4 is connected to the water tank 5, and the outlet is connected to the nozzle 3, used to control the water spray from the nozzle 3.

[0035] In this embodiment, the water pump 4 and the water storage tank 5 are located outside the environmental test chamber 2, and are connected to the nozzle 3 via pipes passing through the chamber wall of the environmental test chamber 2, thereby reducing the space occupied inside the environmental test chamber 2 and reducing the impact on the temperature inside the environmental test chamber 2. In other embodiments, the water pump 4 and the water storage tank 5 can also be located inside the environmental test chamber 2, and the environmental test chamber 2 is also equipped with a circulation mechanism to recover the water sprayed from the nozzle 3 into the water storage tank 5, thereby achieving recycling and reducing heat transfer between the environmental test chamber 2 and the outside environment.

[0036] In this embodiment, the handlebar 100 can be clamped on the handlebar clamp 11 in a vertical direction, and the end of the handlebar 100 covered with the handlebar sleeve 200 faces downward. The pulling assembly 13 includes a first driving member 131, a lifting platform 132 and a load 133. The lifting platform 132 is used to carry the load 133. The load 133 can be connected to the handlebar sleeve clamp 12. The lifting platform 132 is located at the output end of the first driving member 131. The first driving member 131 can drive the lifting platform 132 to rise or fall. During testing, the load 133 is first connected to the handlebar grip 200 via the grip clamp 12. The lifting platform 132 is then raised by the first drive component 131 to bear the load 133, thus relieving the handlebar grip 200 of the weight of the load 133. When a pulling force needs to be applied to the handlebar grip 200, the first drive component 131 lowers the lifting platform 132, separating it from the load 133, allowing the handlebar grip 200 to bear the weight of the load 133. This pulling assembly 13 can pull the handlebar grip 200 and handlebar 100 within the environmental test chamber 2, offering advantages such as simple structure, stable operation, and low cost. The first drive component 131 may include, but is not limited to, a pneumatic cylinder, an electric cylinder, or a hydraulic cylinder, etc., and is not limited here.

[0037] like Figure 2 As shown, in another optional embodiment, the immersion mechanism includes a water tank 6 and a drive assembly 7. The water tank 6 is filled with water and has an opening for the handlebars 100 and handlebar grips 200 to pass through. The drive assembly 7 is used to drive the water tank 6 closer to or further away from the handlebars 100 and handlebar grips 200. After the handlebars 100 and handlebar grips 200 are placed in the environmental test chamber 2, the drive assembly 7 first drives the water tank 6 closer to the handlebars 100 and handlebar grips 200, allowing them to enter the water tank 6 through the opening and immerse themselves for a certain period of time. Then, the drive assembly 7 drives the water tank 6 away from the handlebars 100 and handlebar grips 200 and performs a connection strength test, which can also simulate the application scenario of the handlebars 100 and handlebar grips 200 being immersed in water.

[0038] Furthermore, the pulling mechanism 1 also includes a base plate 14, and the handlebar clamp 11 includes a support portion 111 and a gripper 112 disposed on the support portion 111. The gripper 112 is used to clamp the handlebar 100. The support portion 111 is erected on the base plate 14, and the pulling assembly 13 is mounted on the base plate 14. When the handlebar 100 is clamped by the gripper 112, the handlebar sleeve 200 can be opposite to the pulling assembly 13. The support portion 111 is erected on the base plate 14, so that the gripper 112 has a certain height to facilitate clamping the handlebar 100. By setting the handlebar clamp 11 and the pulling assembly 13 on the base plate 14, the pulling mechanism 1 can be made compact and stable.

[0039] Continue as Figure 2 As shown, in another optional embodiment, the pulling mechanism 1 includes a second drive member 134. The handlebar grip clamp 12 can be connected to the output end of the second drive member 134. The second drive member 134 can apply a pulling force to the handlebar 100 in a direction away from the handlebar 100 through the handlebar grip clamp 12. The second drive member 134 can adjust the magnitude of the pulling force. When it is necessary to change the magnitude of the pulling force, there is no need for the operator to replace the load 133, which is beneficial to improving the automation level of the handlebar grip connection strength detection device.

[0040] In addition, the grip 200 is provided with a snap-fit ​​part 210, and the grip clamp 12 is sleeved on the handlebar 100 and can abut against the snap-fit ​​part 210 along the axial direction of the handlebar 100 to achieve a fixed connection between the grip clamp 12 and the grip 200, thereby avoiding a clamping force along the radial direction of the grip 200 between the grip clamp 12 and the grip 200, which is beneficial to ensuring the accuracy of the test results.

[0041] Current testing standards are typically qualitative, determining the connection strength of the grip 200 by observing whether it undergoes relative displacement with the handlebar 100. To facilitate the development of handlebars 100 and grip 200 with better connection strength, the handlebar grip connection strength testing device also includes a displacement detection component. This component detects the displacement of the grip 200 relative to the handlebar 100. Researchers can apply a tensile force sufficient to cause relative displacement between the handlebar 100 and grip 200, and use the displacement detection component to measure the relative displacement value. This allows for quantitative analysis of the connection strength between the grip 200 and handlebar 100 at different temperatures and rates of temperature change, and with different materials or structures. This helps in further developing grips 200 and handlebar 100 with higher connection strength for different usage scenarios.

[0042] The displacement detection components include, but are not limited to, displacement sensors, photoelectric sensors, or direct measurement by a ruler, etc., and are not limited here.

[0043] The following are the operating steps for the handlebar grip connection strength testing device:

[0044] S1: Clamp the handlebar 100 with the grip 200 sleeved thereon to the handlebar fixture 11, and connect the pulling component 13 to the grip 200 through the grip fixture 12.

[0045] S2: Place the pulling mechanism 1 and the handlebar 100 with the grip 200 sleeved thereon into the environmental test chamber 2, and control the immersion mechanism to make the handlebar 100 and the grip 200 in an immersion environment.

[0046] S3: When the temperature in the environmental test chamber 2 is x1, control the pulling component 13 to apply a pulling force b1 away from the handlebar 100 to the grip 200.

[0047] S4: Keep the pulling force b1, and control the temperature of the environmental test chamber 2 to reach x2 at a temperature change rate a1, and detect whether the grip 200 generates displacement relative to the handlebar 100.

[0048] Among them, the specific values of a1, x1, x2, and b1 can all be adjusted according to the test requirements. By using the above-mentioned device for detecting the connection strength between the handlebar and the grip, the connection strength between the handlebar 100 and the grip 200 under temperature change and immersion environment can be detected, which is beneficial to ensuring riding safety.

[0049] For the low-temperature application scenario, the method for detecting the connection strength between the handlebar and the grip in this embodiment can perform low-temperature detection on the handlebar 100 and the grip 200. Specifically, x1 < 0°C < x2, and before step S3, first control the immersion mechanism to stop immersing the grip 200 and the handlebar 100, and control the temperature of the environmental test chamber 2 to decrease to x3 and then increase to x1, where x3 < x1, so as to avoid damage to the immersion mechanism caused by water freezing at too low temperature, and avoid the immersion mechanism freezing together with the handlebar 100 and the grip 200. By first reducing the temperature in the environmental test chamber 2 to x3 to pre-cool the environment in the test chamber and then increasing it to x1, the time required for the environmental test chamber 2 to reach the test temperature can be shortened, the test efficiency can be improved, and the temperature distribution in the environmental test chamber 2 can be made more uniform, which is beneficial to improving the accuracy of the test conditions.

[0050] For the high-temperature application scenario, the method for detecting the connection strength between the handlebar and the grip in this embodiment can perform high-temperature detection on the handlebar 100 and the grip 200. Specifically, x1 > x2 > 0°C. Before step S3, control the temperature of the environmental test chamber 2 to increase to x4 and then decrease to x1, where x4 > x1. By first increasing the temperature in the environmental test chamber 2 to x4 to pre-heat the environment in the test chamber and then decreasing it to x1, the time required for the environmental test chamber 2 to reach the test temperature can be shortened, the test efficiency can be improved, and the temperature distribution in the environmental test chamber 2 can be made more uniform, which is beneficial to improving the accuracy of the test conditions.

[0051] It is easy to understand that the environmental test chamber 2 has a control console. The test personnel can set the required temperature inside the environmental test chamber 2 through the control console, and thus control the temperature environment inside the environmental test chamber 2. Its specific structure is existing technology and will not be described in detail here.

[0052] Furthermore, a1≥3℃ / min can meet the testing requirements for the connection strength between handlebar 100 and handlebar grip 200 in general application scenarios.

[0053] Specifically, in this embodiment, when conducting low-temperature testing, the temperature inside the environmental test chamber 2 is first set to decrease to -6°C, and then increased to -5°C. When the temperature inside the environmental test chamber 2 reaches -5°C, a pulling force of 70N is applied to the handlebar sleeve 200 away from the handlebar 100 through the pulling component 13. Then, the temperature is increased to 5°C at a temperature change rate of 0.33°C / min, which can meet the testing requirements of the current national standard "GB14746-2006 Safety Requirements for Children's Bicycles".

[0054] During high-temperature testing, the temperature inside the environmental test chamber 2 is first raised to 60℃, then lowered to 40℃. When the temperature inside the environmental test chamber 2 reaches 40℃, a tensile force of 100N is applied to the handlebar grip 200 away from the handlebar 100 via the pull assembly 13. The temperature is then increased to 5℃ at a rate of 0.33℃ / min. Since current national standards do not provide testing standards for the connection strength between the bicycle and the handlebar grip 200 under high-temperature conditions, setting the tensile force to 100N ensures a safety margin and further guarantees riding safety.

[0055] Optionally, the values ​​of x1, x2, x3, x4, a1, and b1 can be set adaptively according to specific application scenarios and detection requirements, and are not limited here.

[0056] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
