[0023] In order to make the purpose and advantages of the present invention more clearly understood, the present invention is described in detail below with reference to the following embodiments. It should be understood that the following text is only used to describe one or several specific implementation methods of the present invention and does not strictly limit the scope of protection specifically claimed by the present invention.

[0024] like Figure 1 As shown, a bicycle frame front fork assembly load-bearing test device includes a support platform 1, a detection device 2 is provided in the middle of the support platform 1, a support frame 3 is provided on the support platform 1, and the support frame 3 is located above the detection device 2, a pressing device 4 is provided below the support frame 3, and the pressing device 4 is located between the support frame 3 and the detection device 2, and multiple groups of front fork assemblies 5 are provided between the pressing device 4 and the detection device 2;

[0025] The pressing device 4 includes a push rod 402, and a plurality of second pressure sensors 403 are arranged below the push rod 402;

[0026] The detection device 2 includes a first pressure sensor 202 , and a plurality of first sleeves 201 are arranged above the first pressure sensor 202 .

[0027] In this embodiment, when the load-bearing test of the bicycle front fork is started, multiple sets of front fork assemblies 5 are placed on the detection device 2, and the suspension fork barrels 504 are sequentially placed into the first sleeve 201. The control pressing device 4 is started, and the electric control telescopic rod 401 starts to work, causing the push rod 402 to move downward. The second pressure sensor 403 on the push rod 402 and the second sleeve 404 move together, so that the upper tube 501 enters the second sleeve 404. The push rod 402 continues to move downward. At this time, the second pressure sensor 403 is subjected to force. At the same time, due to the action of the force, the upper tube 501 is subjected to a force, causing the fork crown 502 to move downward. Due to the movement of the fork crown 502, the stroke tube 503 is subjected to a downward force, causing it to move downward, thereby causing the suspension fork barrel 504 to move downward. Due to the action of the force, the first pressure sensor 202 is subjected to pressure, and the pressure data at this time is calculated. By comparing the data of the first pressure sensor 202 and the second pressure sensor 403, the load-bearing condition of the front fork of the straight-line vehicle is analyzed, thereby completing a series of tasks.

[0028] like Figure 2As shown, the clamping device 4 includes an electrically controlled telescopic rod 401, which is fixedly connected to the support frame 3. The other end of the electrically controlled telescopic rod 401 is fixedly connected to a push rod 402. The push rod 402 is fixedly connected to multiple groups of second pressure sensors 403 below, and the second sleeve 404 is fixedly connected below the second pressure sensor 403.

[0029] In the above method, when the bicycle front fork is subjected to a load-bearing test, the control clamping device 4 is started, and the electrically controlled telescopic rod 401 starts working, causing the push rod 402 to move downward, and the second pressure sensor 403 and the second sleeve 404 on the push rod 402 move together, thereby causing the upper tube 501 in the front fork assembly 5 to enter the second sleeve 404.

[0030] like Figures 2 to 4 As shown, the front fork assembly 5 includes an upper tube 501 , a fork crown 502 is fixedly connected to the lower portion of the upper tube 501 , and travel tubes 503 are fixedly connected to both sides of the fork crown 502 , and the travel tube 503 is movably connected to a suspension fork barrel 504 .

[0031] In the above method, when the bicycle front fork is subjected to a load-bearing test, the clamping device 4 moves downward, and the upper tube 501 enters the second sleeve 404 in the clamping device 4 and continues to move. At this time, the upper tube 501 is subjected to force, causing the fork crown 502 to move downward. Due to the movement of the fork crown 502, the stroke tube 503 has a downward force, causing it to move downward, thereby causing the suspension fork barrel 504 to move downward. Due to the action of the force, the first pressure sensor 202 is subjected to pressure, thereby calculating the pressure data at this time.

[0032] like Figure 3 As shown, grooves are opened on the inner sides of both ends of the support frame 3, and the electric-controlled telescopic rod 401 is arranged above the grooves of the support frame 3.

[0033] In the above manner, the electrically controlled telescopic rod 401 is fixedly arranged above the groove of the support frame 3, so that the pressing device 4 can better press the front fork assembly 5 downward and greatly improve the service life of the electrically controlled telescopic rod 401.

[0034] like Figures 1 to 3 As shown, a groove is opened in the middle of the support platform 1, and the detection device 2 is arranged in the groove of the support platform 1.

[0035] In the above method, when the bicycle front fork is subjected to a load-bearing test, the control clamping device 4 is activated, driving the push rod 402 to move downward, so that the front fork assembly 5 is squeezed downward. At this time, the suspension fork barrel 504 in the front fork assembly 5 is squeezed downward in the first sleeve 201, so that the first pressure sensor 202 is subjected to pressure, and data analysis of the pressure is performed.

[0036] like Figure 2 and Figure 4 As shown, the second sleeve 404 in the pressing device 4 matches the upper tube 501 in the front fork assembly 5 and corresponds one to one, and the first sleeve 201 in the detection device 2 matches the suspension fork barrel 504 in the front fork assembly 5 and corresponds one to one.

[0037] In the above method, the second sleeve 404 corresponds to the upper tube 501 one-to-one, and the first sleeve 201 corresponds to the suspension fork barrel 504 one-to-one. This is so that when the worker places the front fork assembly 5, he can directly put the suspension fork barrel 504 into the corresponding first sleeve 201 and control the clamping device 4 to move downward. At this time, the second sleeve 404 directly covers the upper tube 501 and moves downward. This process does not require manual assistance.

[0038] The working principle of the utility model is as follows: multiple sets of front fork assemblies 5 are placed on the detection device 2, and the suspension fork barrels 504 are placed into the first sleeve 201 in turn. The control pressing device 4 is started, and the electronically controlled telescopic rod 401 starts to work, causing the push rod 402 to move downward. The second pressure sensor 403 and the second sleeve 404 on the push rod 402 move accordingly, so that the upper tube 501 enters the second sleeve 404, and the push rod 402 continues to move downward. At this time, the second pressure sensor 403 is acted upon by a force and starts to calculate data. At the same time, due to the action of the force, the upper tube 501 is acted upon, causing the fork crown 502 to move downward. Due to the movement of the fork crown 502, the stroke tube 503 has a downward force, causing it to move downward, thereby causing the suspension fork barrel 504 to move downward. Due to the action of the force, the first pressure sensor 202 is subjected to pressure, and the pressure data at this time is calculated. By comparing the data of the first pressure sensor 202 and the second pressure sensor 403, the load-bearing condition of the front fork of the straight-line vehicle is analyzed, thereby completing a series of tasks.

[0039] The above is only a preferred embodiment of the present invention. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of the present invention, and such improvements and modifications should also be considered within the scope of protection of the present invention. Structures, devices, and operating methods not specifically described and explained in this application shall be implemented in accordance with conventional means in the art unless otherwise specified or limited.
