Description

Technical Field

[0001] This utility model relates to the field of vehicle frame fork testing technology, and in particular to a vehicle frame fork testing device. Background Technology

[0002] With the increasing popularity of electric tricycles, their safety and durability are receiving more and more attention from consumers. As an important component of electric tricycles, the front fork of the frame not only bears the weight of the front of the vehicle, but also directly affects the vehicle's handling, stability and comfort. Its strength and rigidity are directly related to whether the vehicle can effectively cope with road vibrations, bumps and the load when turning during driving, thus affecting the overall driving safety and durability.

[0003] Application No. 202023256959.1 discloses an impact resistance tester for electric vehicle frame front fork assemblies, including a base plate. A pad is fixed at the middle of the upper surface of the base plate, and upright plates are symmetrically fixed at both ends of the upper surface of the base plate. A top plate is connected to the top of the upright plates. A first fixed pulley is installed on the lower surface of the top plate, and a second fixed pulley is installed on the upper end of the side wall of the upright plates. The test device designed by this utility model has a simple structure and is easy to operate. It can be operated by a single person. During the test, the front fork assembly to be tested is placed on the pad, and then the steel wire rope is pulled to raise the connecting plate. After it rises to a higher position, the hand is released, and the connecting plate falls freely. The impact hammer strikes the front fork assembly, and its impact resistance performance can be judged by observing the condition of the front fork assembly. The test speed is fast and meets the needs of impact resistance testing of large batches of frame front fork assemblies.

[0004] The above-mentioned solution has shortcomings in its use. It does not fix the front fork of the frame. When the impact hammer hits the front fork of the frame, it may cause the front fork to tilt or shift. Since the front fork of the frame usually bears vertical forces during actual use, most of these forces act along the vertical axis of the front fork of the frame. When the front fork is not fixed, the external impact force may cause the direction of the force to deviate, resulting in uneven force on the front fork. This uneven force state will cause the force distribution of the front fork of the frame to be inconsistent with normal use, thus affecting the results of the impact test. Therefore, we provide a frame front fork testing device. Utility Model Content

[0005] This invention provides a frame front fork testing device to solve the technical problems existing in the background art.

[0006] The purpose and effect of this utility model, a bicycle frame front fork testing device, are achieved by the following specific technical means: A bicycle frame front fork testing device, comprising a frame:

[0017] Beneficial effects:

[0018] 1. Through the cooperation of the fixed component and the test component, the fixed component can stably clamp and support the frame fork, ensuring that the frame fork remains stable during the impact test. When the test component applies an impact to the frame fork, the fixed component can prevent the fork from shifting, tilting, or deforming irregularly during the force application, thus ensuring that the fork can withstand the vertical impact force from the test component in the expected direction. The direction and magnitude of this force are consistent with the force encountered by the fork under actual use, thereby ensuring the results of the impact test. The shielding component can shield both sides of the frame to prevent debris from the impact test from accidentally injuring the staff.

[0019] 2.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0028] First Embodiment

[0029] As attached Figure 1 Appendix Figure 2 Appendix Figure 3 With appendix Figure 4 As shown: A frame fork testing device includes a frame 1, with support legs 5 fixedly connected to the four corners of the frame 1. The support legs 5 can support the frame 1 to ensure that the frame 1 remains stable when the frame fork is subjected to an impact test.

[0030] The fixing component 2, located at the bottom of the interior of the frame 1, includes a carrier plate 201 mounted on the inner wall of the frame 1, a set of through slots 202 formed on the upper surface of the carrier plate 201, and a clamping structure mounted on the carrier plate 201 for fixing the frame fork. The clamping mechanism of the fixing component 2 includes two arc-shaped plates 203 fixedly connected to the upper surface of the carrier plate 201 and two electric push rods 204 mounted on the bottom surface of the carrier plate 201. The bottom ends of the two electric push rods 204 are fixedly connected to a lifting plate 205. Push-pull plates 206 are hinged to both ends of the lifting plate 205. L-shaped plates 207 are hinged to the ends of the two push-pull plates 206 that are far apart from each other. The top of the shaped plate 207 is through the through groove 202 and fixedly connected to the clamping plate 208. The arc plate 203 can fix one side of the frame fork. Then, the electric push rod 204 is activated to extend, the lifting plate 205 will descend and pull one end of the push-pull plate 206 to descend. At the same time, the other end of the push-pull plate 206 will pull the L-shaped plate 207. The L-shaped plate 207 will push the clamping plate 208 to move, thereby forming a clamping and fixing of the frame fork. This ensures that the frame fork can withstand the vertical impact force from the test component 3 in the expected direction. The direction and magnitude of this force are consistent with the force encountered by the fork under actual use, thus ensuring the results of the impact test.

[0031] Each push-pull plate 206 has a stabilizing groove 209 on its upper surface. A stabilizing plate 210 is slidably connected to the inner wall of each stabilizing groove 209. The top of each stabilizing plate 210 is connected to the bottom surface of the carrier plate 201, and the bottom of each carrier plate 201 is connected to the upper surface of the bottom of the frame 1. By using the cooperation of the stabilizing groove 209 and the stabilizing plate 210, the push-pull plate 206 can be stabilized, preventing the push-pull plate 206 from deflecting when subjected to force, and avoiding the situation where the push-pull plate 206 is twisted and broken with the lifting plate 205 or the L-shaped plate 207.

[0032] Each L-shaped plate 207 has a T-shaped plate 211 fixedly connected to its front and back sides. Each T-shaped plate 211 has a set of auxiliary wheels 212 mounted on its upper surface. Each auxiliary wheel 212 is in contact with the bottom surface of the carrier plate 201. The cooperation between the T-shaped plate 211 and the auxiliary wheel 212 can stabilize the L-shaped plate 207 and prevent it from tilting when subjected to force.

[0033] Two frames 213 are fixedly connected to the two clamping plates 208 on their opposite sides. Each frame 213 has a slidably connected plate 214 on its inner wall. The bottom end of each plate 214 is connected to the upper surface of the carrier plate 201. The cooperation between the frame 213 and the plate 214 can support the clamping plate 208, thereby ensuring the smooth movement of the clamping plate 208.

[0035] As attached Figure 1 With appendix Figure 5 As shown: Test component 3 is set inside the top of the frame 1 for impact testing of the frame fork. Test component 3 includes an impact cylinder 301 embedded in the top of the frame 1. An impact plate 302 is installed on the telescopic end of the impact cylinder 301. When the impact cylinder 301 is working, it will push the impact plate 302 down, and the impact plate 302 will then conduct an impact test on the frame fork.

[0036] Third Embodiment

[0037] As attached Figure 1 With appendix Figure 5 As shown: A shielding component 4 is installed on the front and back of the frame 1 to shield and protect the staff. The shielding component 4 includes a set of through slots 401 on both sides of the frame 1. Hydraulic push rods 402 are installed on both sides of the frame 1. Each hydraulic push rod 402 has a connecting plate 403 installed at its telescopic end. The front end and the rear end of the two connecting plates 403 are respectively fixedly connected to a baffle 404. The baffle 404 is slidably connected to the through slot 401. When the hydraulic push rods 402 retract, the connecting plates 403 will pull the baffle 404 down. The baffle 404 will then be positioned in front of and behind the front fork of the frame, thereby preventing the fragments from flying and injuring the staff during the test.

[0038] Working principle: When in use, place the front fork of the frame on the outside of the two arc-shaped plates 203, then activate the electric push rod 204 to extend. The electric push rod 204 will push the lifting plate 205 down, and at the same time, one end of the push-pull plate 206 will descend, while the other end of the push-pull plate 206 will pull the L-shaped plate 207 to move. The L-shaped plate 207 will then push the clamping plate 208 closer to the arc-shaped plate 203, thereby clamping and fixing the front fork of the frame. Then, activate the impact cylinder 301 to extend and allow the impact plate 302 to conduct an impact test on the front fork of the frame, ensuring that the front fork of the frame can withstand vertical forces and guaranteeing the results of the impact test.
