[0036] like Figure 1As shown, this embodiment provides a handlebar grip connection strength detection device for detecting the connection strength between a grip cover 200 mounted on a handlebar 100 and the handlebar 100, wherein the handlebar grip connection strength detection device comprises a pulling mechanism 1, an environmental test chamber 2 and an immersion mechanism, the pulling mechanism 1 comprises a handlebar clamp 11, a grip cover clamp 12 and a pulling assembly 13, the handlebar clamp 11 is used to clamp the handlebar 100, the grip cover clamp 12 is used to be fixedly connected to the grip cover 200, the pulling assembly 13 can be connected to the grip cover clamp 12, and is used to apply a pulling force away from the handlebar 100 to the grip cover 200; the environmental test chamber 2 is used to accommodate the pulling mechanism 1 and the handlebar 100 mounted with the grip cover 200, and the environmental test chamber 2 can adjust its internal temperature and the temperature change rate; the immersion mechanism is arranged in the environmental test chamber 2, and is used to make the handlebar 100 and the grip cover 200 in a water-immersed environment.

[0037] During the test, the handlebar 100 with the grip cover 200 is first clamped on the handlebar clamp 11, and the pulling assembly 13 is connected to the grip cover 200 through the grip cover clamp 12. Then, the connected handlebar 100, the grip cover 200 and the pulling mechanism 1 are placed in the environmental test box 2, and the immersion mechanism is started to put the handlebar 100 and the grip cover 200 in a water-immersed environment. The temperature and the temperature change rate in the environmental test box 2 are adjusted to simulate a temperature change environment. When the ambient temperature changes, a pulling force is applied to the grip cover 200 away from the handlebar 100 through the pulling assembly 13, and the test is performed. Whether the grip cover 200 is displaced relative to the handlebar 100 can determine whether the connection strength between the handlebar 100 and the grip cover 200 is qualified under temperature changes and water immersion environments, which is beneficial to ensuring riding safety; and the connection strength between the handlebar 100 and the grip cover 200 is detected by the above-mentioned detection device, and the connection strength between the handlebar 100 and the handlebar 100 is compared with the material, structure, temperature and temperature change rate as variables, which can also help develop grip covers 200 and handlebars 100 with higher connection strength for different usage scenarios, which is helpful to promote industry progress.

[0038] Continue as Figure 1 As shown, specifically, the immersion mechanism includes a nozzle 3, which is used to spray water to the handlebar 100 and the grip cover 200 to simulate the application scenario that the gap between the handlebar 100 and the grip cover 200 may be immersed in rainwater in outdoor rainy weather. The tester can adjust the water spraying amount according to the test requirements to detect the connection strength between the handlebar 100 and the grip cover 200 in extreme weather, which can meet various test requirements. Furthermore, the handlebar grip cover connection strength detection device also includes a water pump 4 and a water reservoir 5. The water inlet end of the water pump 4 is connected to the water reservoir 5, and the water outlet end is connected to the nozzle 3, which is used to control the nozzle 3 to spray water.

[0039] In this embodiment, the water pump 4 and the water reservoir 5 are arranged outside the environmental test box 2, and are connected to the nozzle 3 through a pipeline passing through the box wall of the environmental test box 2, so as to reduce the occupation of the space in the environmental test box 2 and reduce the impact on the temperature in the environmental test box 2. In other embodiments, the water pump 4 and the water reservoir 5 can also be arranged in the environmental test box 2, and the environmental test box 2 is further provided with a circulation mechanism for recycling the water sprayed by the nozzle 3 into the water reservoir 5 to achieve recycling and reduce the heat transfer between the environmental test box 2 and the outside world.

[0040] In this embodiment, the handlebar 100 can be clamped on the handlebar clamp 11 in the vertical direction, and one end of the handlebar 100 provided with the grip cover 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 grip cover clamp 12. The lifting platform 132 is arranged 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 the test, the load 133 is first connected to the handle cover 200 through the handle cover fixture 12, and the lifting platform 132 is driven to rise by the first driving member 131 to carry the load 133, so that the handle cover 200 is not affected by the gravity of the load 133. When it is necessary to apply a pulling force to the handle cover 200, the first driving member 131 drives the lifting platform 132 to descend, so that the lifting platform 132 and the load 133 are separated, so that the handle cover 200 bears the gravity of the load 133. The above-mentioned pulling assembly 13 can pull the handle cover 200 and the handlebar 100 in the environmental test box 2, and has the advantages of simple structure, stable operation and low cost. Among them, the first driving member 131 includes but is not limited to a cylinder, an electric cylinder or a hydraulic cylinder, etc., which are not limited here.

[0041] like Figure 2 As shown, in another optional embodiment, the immersion mechanism includes a water tank 6 and a driving assembly 7. The water tank 6 contains water, and an opening is provided on the water tank 6 for the handlebar 100 and the grip cover 200 to pass through. The driving assembly 7 is used to drive the water tank 6 to approach or move away from the handlebar 100 and the grip cover 200. After the handlebar 100 and the grip cover 200 are placed in the environmental test chamber 2, the driving assembly 7 first drives the water tank 6 to approach the handlebar 100 and the grip cover 200, so that the handlebar 100 and the grip cover 200 enter the water tank 6 through the opening and soak for a certain period of time; then the driving assembly 7 drives the water tank 6 away from the handlebar 100 and the grip cover 200, and performs a connection strength test, which can also simulate the application scenario of the handlebar 100 and the grip cover 200 being immersed in water.

[0042] Furthermore, the pulling mechanism 1 also includes a base plate 14, the handlebar clamp 11 includes a support portion 111 and a clamping jaw 112 arranged on the support portion 111, the clamping jaw 112 is used to clamp the handlebar 100, the support portion 111 is vertically arranged on the base plate 14, the pulling assembly 13 is installed on the base plate 14, when the handlebar 100 is clamped by the clamping jaw 112, the handle cover 200 can be opposite to the pulling assembly 13, the support portion 111 is vertically arranged on the base plate 14, so that the clamping jaw 112 has a certain height, so as to clamp the handlebar 100, by arranging the handlebar clamp 11 and the pulling assembly 13 on the base plate 14, the pulling mechanism 1 can be compact and stable.

[0043] Continue as Figure 2 As shown, in another optional embodiment, the pulling mechanism 1 includes a second driving member 134, the handle cover clamp 12 can be connected to the output end of the second driving member 134, the second driving member 134 can apply a pulling force in a direction away from the handlebar 100 to the handlebar 100 through the handle cover clamp 12, and the second driving member 134 can adjust the pulling force. When the pulling force needs to be changed, there is no need for the staff to replace the load 133, which is beneficial to improving the degree of automation of the handlebar cover connection strength detection device.

[0044] In addition, a clamping portion 210 is provided on the handlebar 200, and the handlebar clamp 12 is mounted on the handlebar 100 and can abut against the clamping portion 210 along the axial direction of the handlebar 100 to achieve a fixed connection between the handlebar clamp 12 and the handlebar 200, avoiding the existence of a clamping force between the handlebar clamp 12 and the handlebar 200 along the radial direction of the handlebar 200, which is beneficial to ensure the accuracy of the detection result.

[0045] The current testing standards are usually qualitative tests, which determine whether the connection strength is qualified by observing whether the grip cover 200 has a relative displacement with the handlebar 100. In order to facilitate the development of handlebars 100 and grip cover 200 with better connection strength, the handlebar grip cover connection strength detection device also includes a displacement detection member, which is used to detect the displacement of the grip cover 200 relative to the handlebar 100. Researchers can use a pulling force sufficient to cause the handlebar 100 and grip cover 200 to have a relative displacement, and detect the value of the relative displacement through the displacement detection member, thereby quantitatively analyzing the connection strength between the grip cover 200 and the handlebar 100 of different temperatures and temperature change rates, and different materials or structures, which is helpful to further develop grip covers 200 and handlebars 100 with higher connection strength for different usage scenarios.

[0046] The displacement detection element includes, but is not limited to, a displacement sensor, a photoelectric sensor, or direct measurement by a ruler, etc., which is not limited here.

[0047] This embodiment also provides a method for detecting the connection strength of a handlebar grip, which uses the handlebar grip connection strength detection device of any of the above embodiments and can detect the connection strength between the handlebar 100 and the grip 200 under temperature changes and immersion environments. The method includes the following steps:

[0048] S1: Clamp the handlebar 100 with the grip 200 sleeved thereon in the handlebar fixture 11, and connect the pulling component 13 to the grip 200 through the grip fixture 12.

[0049] 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.

[0050] S3: Control the pulling component 13 to apply a pulling force b1 away from the handlebar 100 to the grip 200 when the temperature in the environmental test chamber 2 is temperature x1.

[0051] S4: Keep the pulling force b1, and control the temperature of the environmental test chamber 2 to reach temperature x2 at a temperature change rate a1, and detect whether the grip 200 has a displacement relative to the handlebar 100.

[0052] Among them, the specific values of a1, x1, x2, and b1 can all be adjusted according to test requirements. By using the above handlebar grip connection strength detection device, the connection strength between the handlebar 100 and the grip 200 under temperature changes and immersion environments can be detected, which is beneficial to ensuring riding safety.

[0053] For low-temperature application scenarios, the handlebar grip connection strength detection method of 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 due to water freezing at too low a 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.

[0054] In order to target high-temperature application scenarios, the handlebar grip connection strength detection method of this embodiment can perform high-temperature detection on the handlebar 100 and the grip 200. Specifically, x1>x2>0°C. Before step S3, the temperature of the environmental test box 2 is controlled to increase to x4 and then decrease to x1, wherein x4>x1. By first increasing the temperature in the environmental test box 2 to x4, preheating the environment in the test box, and then decreasing it to x1, the time required for the environmental test box 2 to reach the test temperature can be shortened, the test efficiency can be improved, and the temperature distribution in the environmental test box 2 can be made more uniform, which is conducive to improving the accuracy of the test conditions.

[0055] It is easy to understand that the environmental test box 2 has a control console, and the test personnel can control the temperature environment in the environmental test box 2 by setting the required temperature inside the environmental test box 2 through the control console. Its specific structure belongs to the existing technology and will not be described in detail here.

[0056] Furthermore, a1≥3°C / min, which can meet the detection requirements of the connection strength between the handlebar 100 and the grip cover 200 in general application scenarios.

[0057] Specifically, in this embodiment, when performing low-temperature testing, the temperature in the environmental test box 2 is first set to be lowered to -6°C and then raised to -5°C. When the temperature in the environmental test box 2 reaches -5°C, a pulling force of 70N is applied to the handlebar 200 away from the handlebar 100 through the pulling assembly 13, and then the temperature is raised 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".

[0058] When performing high temperature testing, the temperature in the environmental test chamber 2 is first set to rise to 60°C, then lowered to 40°C. When the temperature in the environmental test chamber 2 reaches 40°C, a pulling force of 100N is applied to the grip cover 200 away from the handlebar 100 through the pulling assembly 13, and then the temperature is raised to 5°C at a temperature change rate of 0.33°C / min. Since the current national standard does not provide a testing standard for the connection strength between the handlebar and the grip cover 200 in a high temperature environment, by setting the pulling force to 100N, a safety margin can be guaranteed, further ensuring riding safety.

[0059] Optionally, according to specific application scenarios and detection requirements, the values ​​of x1, x2, x3, x4, a1 and b1 can be adaptively set and are not limited here.

[0060] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the embodiments of the present invention. For those skilled in the art, various obvious changes, readjustments and substitutions can be made without departing from the protection scope of the present invention. It is not necessary and impossible to list all the embodiments here. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the claims of the present invention.
