[0033] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention, but this does not constitute a limitation on the scope of protection of the present invention.

[0034] In this invention, for clarity, the following description is provided: The observer faces the attached... Figure 1In this observation, the left side of the observer is designated as front, the right side as rear, the front of the observer as right, the rear of the observer as left, the top of the observer as up, and the bottom of the observer as down. It should be noted that the terms "front end," "rear end," "left side," "right side," "middle," "above," and "below" used in this document indicate orientations or positional relationships based on the accompanying drawings. These are merely for the purpose of clearly describing the invention and do not indicate or imply that the structures or components referred to must have a specific orientation or be constructed in a specific orientation; therefore, they should not be construed as limitations on the invention. Furthermore, the terms "first," "second," "third," and "fourth" are used only for the purpose of clarity or simplification of description and should not be construed as indicating or implying relative importance or quantity.

[0035] See Figures 1 to 9 This embodiment provides a special testing machine for shock absorber vehicles, including a frame 1. The frame 1 is provided with a front platform 101, a middle platform 102 and a rear platform 103 arranged from front to back. The height of the front platform 101 is higher than the height of the rear platform 103, and the height of the middle platform 102 is lower than the height of the rear platform 103.

[0036] The front platform 101 is equipped with a head tube test channel 2, the left bottom bracket test channel 3 and the right bottom bracket test channel 4 are respectively provided on the left and right sides of the middle platform 102, and the seat tube test channel 5 and the disc brake test channel 6 are respectively provided on the front and rear sides of the rear platform 103.

[0037] The head tube test channel 2 includes a first servo cylinder 201 and a guide rail 202 extending back and forth. A first movable plate 203 is provided on the guide rail 202. The first drive rod 2011 of the first servo cylinder 201 can drive the first movable plate 203 to slide back and forth along the guide rail 202. A rotating support frame 2031 is provided on the first movable plate 203. The rotating support frame 2031 is movably connected to one end of the simulated shock-absorbing bicycle front fork rotating rod 204. In actual application: First, the simulated shock-absorbing bicycle front fork rotating rod 204 is inserted into the head tube 9 of the shock-absorbing bicycle frame 8 and fixed. The specific fixing method can be selected according to the actual situation, thereby achieving support for the front end of the shock-absorbing bicycle frame. Then, the first movable plate slides back and forth along the guide rail 202 under the drive of the first servo cylinder. The force generated by the sliding of the first movable plate will be transmitted to the head tube through the simulated shock-absorbing bicycle front fork rotating rod 204, thereby realizing the work of testing the strength of the head tube.

[0038] The left five-way test channel 3 includes a second servo cylinder 301, and the top of the second servo cylinder 301 is provided with a second drive rod 3011. The right five-way test channel 4 includes a third servo cylinder 401, and the top of the third servo cylinder 401 is provided with a third drive rod 4011. The tops of the second drive rod 3011 and the tops of the third drive rod 4011 are respectively connected and fixed to the left and right ends of the five-way fixing rod 7.

[0039] The seat tube test channel 5 includes a fourth servo cylinder 501. The top of the fourth servo cylinder 501 is provided with a fourth drive rod 5011, and the top of the fourth drive rod 5011 is provided with a vertical rod 502. The fourth drive rod 5011 of the fourth servo cylinder 501 can drive the vertical rod 502 to move in the vertical direction. The vertical rod 502 is provided with a mounting hole 5021. In actual use: the vertical rod is installed in the U-shaped groove 16 of the horizontal plate 15 on the seat tube 12, and the mounting hole of the vertical rod is connected and fixed to the fixing holes 17 on both sides of the U-shaped groove 16 by a pin. Thus, under the drive of the fourth servo cylinder 501, the vertical rod continuously drives the horizontal plate to swing up and down, thereby simulating the actual use scenario and realizing the accurate testing of the seat tube strength.

[0040] The disc brake test channel 6 includes a fifth servo cylinder 601 and a vertically extending fixed rod 602. The top of the fixed rod 602 has a horizontal rod 603 extending left and right. The horizontal rod 603 is rotatably connected to a rotating wheel 604. A connecting block 605 is provided on the front edge of the rotating wheel 604. The fifth drive rod 6011 of the fifth servo cylinder 601 can drive the rotating wheel 604 to rotate around the horizontal rod 603. In practical application: the connecting block is fixedly connected to the disc brake mounted on the disc brake seat 20 of the suspension frame 8. Driven by the fifth servo cylinder 601, the rotating wheel rotates around the horizontal rod 603, thereby driving the movement of the connecting block, ultimately achieving a strength test on the disc brake seat of the suspension frame. Furthermore, both ends of the horizontal rod are fixedly fitted with the connecting holes 18 at the rear end of the suspension frame's vertical fork 13 and horizontal fork 14 to fix and support the rear end of the suspension frame.

[0041] Function: The platform has left and right bottom bracket test channels on its left and right sides, respectively. The left bottom bracket test channel includes a second servo cylinder with a second drive rod at its top. The right bottom bracket test channel includes a third servo cylinder with a third drive rod at its top. The tops of the second and third drive rods are connected and fixed to the left and right ends of the bottom bracket fixing rod, respectively. Therefore, when testing the bottom bracket of a shock absorber frame, after passing the bottom bracket fixing rod through the bottom bracket, the strength of the bottom bracket can be tested using the left and right bottom bracket test channels. There are three types of strength tests available for the shock absorber bottom bracket test channels (including the left and right bottom bracket test channels). Situations: (1) Single-cylinder (unidirectional) test: This refers to only one of the servo cylinders in the second servo cylinder of the left five-way test channel and the third servo cylinder of the right five-way test channel driving up and down, while the other servo cylinder does not drive. This test is required by the customer. (2) Double-cylinder test in the same direction: This refers to the second servo cylinder of the left five-way test channel and the third servo cylinder of the right five-way test channel driving up and down simultaneously. This test is required by the customer. (3) Asynchronous test of double-cylinder test: This refers to one of the servo cylinders in the second servo cylinder of the left five-way test channel and the third servo cylinder of the right five-way test channel driving down, while the other servo cylinder drives up. This test is required by the customer. Therefore, this invention can test five items at once, namely three items tested by the head tube test channel, seat tube test channel, and disc brake test channel, and two items tested by the left five-way test channel and the right five-way test channel (that is, the left and rear sides of the five-way can be tested separately), which greatly improves work efficiency and can also realize single-item strength test, which can better meet the diverse test strength requirements of customers.

[0042] The first part, which will introduce the left five-way test channel and the right five-way test channel in detail below:

[0043] Specifically, the top of the second drive rod 3011 is provided with a second load cell 302, and the top of the second load cell 302 is provided with a first connector 303. The first connector 303 has a first mounting hole 3031 extending from left to right in the middle. The top of the third drive rod 4011 is provided with a third load cell 402, and the top of the third load cell 402 is provided with a second connector 403. The second connector 403 has a second mounting hole 4031 extending from left to right in the middle. The first mounting hole 3031 and the second mounting hole 4031 can be respectively fitted and fixed to the left and right ends of the bottom bracket fixing rod 7. Function: The first connector and the second connector facilitate the connection between the second drive rod and the bottom bracket fixing rod.

[0044] Specifically, the intermediate platform 102 is provided with a first slide groove 1021 extending left and right, and the left five-way test channel 3 and the right five-way test channel 4 are provided on the first slide groove 1021; the left five-way test channel 3 also includes a second moving plate 304, and a second servo electric cylinder 301 is provided on the second moving plate 304. The second moving plate 304 and the first slide groove 1021 can be slidably engaged and locked in a left and right manner; the right five-way test channel 4 also includes a third moving plate 404, and a third servo electric cylinder 401 is provided on the third moving plate 404. The third moving plate 404 and the first slide groove 1021 can be slidably engaged and locked in a left and right manner. Function: The second moving plate 304 and the first slide groove 1021 can slide left and right and lock together, and the third moving plate 404 and the first slide groove 1021 can slide left and right together. This allows the two moving plates (i.e., the second moving plate and the third moving plate) to move away from or closer to each other. When the second moving plate and the third moving plate slide left and right, the first connector and the second connector will also slide left and right on the bottom bracket fixing rod with the same amplitude. The purpose of this is to facilitate the connection of the first connector and the second connector to the bottom bracket fixing rod at the appropriate position for testing.

[0045] Specifically, the top front and rear sides of the second moving plate 304 are respectively provided with first support blocks 3041, and the first support blocks 3041 on the front and rear sides are respectively connected and fixed to the front and rear ends of the first rotating shaft 3042. The bottom of the second servo electric cylinder 301 is provided with a first rotating plate 3012, and the first rotating plate 3012 is rotatably engaged with the first rotating shaft 3042. The top front and rear sides of the third moving plate 404 are respectively provided with second support blocks 4041, and the second support blocks 4041 on the front and rear sides are respectively connected and fixed to the front and rear ends of the second rotating shaft 4042. The bottom of the third servo electric cylinder 401 is provided with a second rotating plate 4012, and the second rotating plate 4012 is rotatably engaged with the second rotating shaft 4042. Function: By rotating the first rotating plate 3012 and the first rotating shaft 3042 in a coordinated manner, and by rotating the second rotating plate 4012 and the second rotating shaft 4042 in a coordinated manner, the second and third servo electric cylinders can swing left and right around the first and second rotating shafts. This swinging motion facilitates the connection of the first and second connectors to the bottom bracket fixing rod and allows for more vivid simulation testing. During testing, the second and third moving plates are locked in place and will not slide left or right, so the first and second connectors will also not slide left or right. Sliding is only required when installing the frame. The first and second rotating shafts are provided to facilitate frame installation and simulation testing.

[0046] The second part, which will describe the head tube test channel in detail below:

[0047] Specifically, the first servo cylinder 201 is located in front of the guide rail 202. A first drive rod 2011 is located at the rear end of the first servo cylinder 201, and a first load cell 2012 is located at the rear end of the first drive rod 2011. The rear end of the first load cell 2012 is detachably connected to the front end of the first moving plate 203. The first moving plate 203 and the guide rail 202 can slide and lock in a forward-backward engagement. A rotating support frame 2031 has a rotating groove 2032, and the left and right side walls of one end of the simulated shock absorber front fork rotating rod 204 are rotatably connected to the left and right side walls of the rotating groove 2032, respectively. Function: The first moving plate 203 and the guide rail 202 can slide and lock in a forward-backward engagement. When sliding in a forward-backward engagement, the head tube strength can be tested; when locked, interference between the head tube testing channel and other testing channels can be avoided.

[0048] Part Three, which follows, will introduce the seat tube test channel in detail:

[0049] Specifically, the top of the fourth drive rod 5011 is provided with a fourth load cell 5012, and the top of the fourth load cell 5012 is connected and fixed to the bottom of the vertical rod 502; the vertical rod 502 is provided with a number of mounting holes 5021 distributed sequentially in the vertical direction. Function: Since the vertical rod is provided with a number of mounting holes distributed sequentially in the vertical direction, it can adapt to different sizes of frames by matching different mounting holes with the fixing holes 17, thereby improving adaptability.

[0050] Part Four, the following section will introduce the disc brake test channel in detail:

[0051] Specifically, the lower edge of the rotating wheel 604 is provided with a downwardly extending swing rod 606. The fifth servo electric cylinder 601 is located behind the fixed rod 602. The front end of the fifth servo electric cylinder 601 is provided with a fifth drive rod 6011. The front end of the fifth drive rod 6011 is provided with a fifth load cell 6012. The front end of the fifth load cell 6012 is provided with a connecting part 6013. The connecting part 6013 is provided with a movable groove 6014 that is open on the front, upper and lower sides. The movable groove 6014 is provided with a third rotating shaft that extends in the left and right directions. The bottom end of the swing rod 606 is provided with a shaft hole that extends axially in the left and right directions. The shaft hole is movably connected to the third rotating shaft. There is a gap between the shaft hole and the third rotating shaft. There is a gap between the swing rod 606 and the rear side wall of the movable groove 6014, so that the back-and-forth movement of the fifth drive rod 6011 can drive the swing rod 606 to swing up and down. Function: Driven by the fifth servo cylinder, the swing arm swings up and down under force, thereby performing a strength test on the disc brake mount of the suspension frame. Since the movement amplitude required for the disc brake mount strength test is small, the swing amplitude required for the swing arm is also small. Therefore, setting a gap between the shaft hole and the third rotating shaft can meet the swing arm's swing requirements.

[0052] Specifically, the two ends of the horizontal rod 603 pass through the left and right sides of the fixed rod 602, respectively. The rotating wheel 604 is located on the left or right side of the fixed rod 602. The horizontal rod 603 is configured as a sleeve, and its two ends are threadedly connected to quick-release screws. Function: When the horizontal rod 603 is configured as a sleeve, the quick-release screws can be used to engage with the two ends of the sleeve, thereby locking the rear end of the shock absorber frame.

[0053] Specifically, the front side of the top of the rear platform 103 is provided with a second slide groove 1031 extending forward and backward, and the rear side of the top of the rear platform 103 is provided with a third slide groove 1032 extending left and right.

A fourth servo electric cylinder 501 and a fixing rod 602 are provided on the fourth moving plate 1033. A fifth moving plate 1034 is provided on the third slide groove 1032.
