Description

Technical Field

[0001] The present invention relates to the technical field of automobile chassis compression test, and in particular to a new energy automobile chassis compression test device and a test method thereof. Background Art

[0002] During automobile design and production, new energy vehicles need to be subjected to chassis load testing. However, existing chassis load testing devices on the market usually apply pressure to the chassis as a whole, but it is difficult to test each position on the chassis individually, resulting in low accuracy of the load test and inability to obtain load capacity data for each part of the chassis.

[0003] In response to the above problems, Chinese utility model patent CN220625763U discloses a new energy vehicle chassis load testing device, which places the vehicle chassis on the top surface of the test platform, starts the longitudinal moving component and the lateral moving component to drive the pressure testing mechanism to move longitudinally and laterally to the specified position through the support plate, the first slide groove, the connecting plate and the slider, starts the fixing mechanism to clamp the fixed chassis, and starts the pressure testing mechanism to perform load testing at the specified test point on the vehicle chassis.

[0004] Although the above-mentioned new energy vehicle chassis load test device realizes load testing at designated test points on the vehicle chassis, some problems are still exposed in actual use. When the pressure plate is used to apply pressure to simulate the chassis compression resistance, once pressure is applied to a certain suspension on the chassis, the suspension will deform and shrink, causing the chassis to tilt. Since the pressure plate can only maintain a horizontal state, the pressure plate cannot fit tightly and evenly with the chassis after the chassis tilts. As a result, in subsequent compression tests, the distribution of pressure on the chassis will become uneven, which will eventually have a negative impact on the accuracy of the test. In addition, after the pressure plate is tilted, its contact surface with the chassis will be reduced accordingly, which will not only make it easier for the two to shift, but also this shift will also cause adverse interference to the test accuracy, thereby reducing the reliability and accuracy of the test device in actual applications.

[0005] Therefore, we propose a new energy vehicle chassis compression test device and a test method thereof to solve the above-mentioned problems. Summary of the invention

[0006] The purpose of the present invention is to provide a new energy vehicle chassis compression test device and a test method thereof, so as to solve the problem proposed in the above background technology that when the suspension on the chassis is subjected to a compression test, after pressure is applied to a suspension on the chassis, the suspension will produce a certain deformation, causing the suspension structure to shrink, while other suspension structures will shrink slightly or remain unchanged, which will cause the chassis to tilt to a certain extent. Since the pressure plate can only remain horizontal with the chassis, the pressure plate cannot fit tightly with the chassis after the chassis tilts. Subsequently, when the compression test is performed, the pressure applied to the chassis is not uniform, which will affect the accuracy of the test. Moreover, after the pressure plate is tilted, the contact surface is reduced, which makes it easy for the pressure plate and the chassis to shift, affecting the test accuracy.

[0022] Compared with the prior art, the beneficial effects of the present invention are as follows: the new energy vehicle chassis compression test device and the test method thereof are provided with a test assembly above the base, and then when the compression test is performed on the suspension part of the chassis, the pressing plate is tilted together with the chassis after the chassis is tilted, and the pressing plate is not easy to shift after the tilt, and the fixed position of the pressing plate will not change, thereby avoiding the displacement of the chassis and avoiding the uneven pressure on the pressing plate to affect the test accuracy, thereby improving the practicality; 1. When the chassis of new energy vehicles is subjected to compression test, the chassis is provided with four wheels, and the chassis can be moved to the top of the base, and then the position of the mounting plate is adjusted by the adjusting assembly. When each suspension on the chassis is subjected to compression test, the movable plate can be driven to move downward by extending the hydraulic cylinder. During the downward movement, the movable plate drives the guide rod to slide on the positioning block, and the movement of the movable plate is limited, so that the pressure plate contacts the chassis, and then pressure is applied to the chassis by the hydraulic cylinder. After one suspension on the chassis is subjected to pressure, the suspension will shrink, while the other three suspensions will shrink slightly or remain unchanged, which will drive the chassis to tilt to a certain extent. After the chassis tilts, the pressure plate can fit closely with the chassis, and the pressure plate rotates with the tilt of the chassis, so that the spherical part can be driven to rotate on the movable plate. After the spherical part rotates, the swing rod can be driven to rotate. Regardless of the rotation direction of the spherical part, one of the mounting rods can be driven to tilt upward, and then the movable plate can be pushed upward by the ball bearing, so that the movable plate slides on the support rod and compresses the telescopic spring, and the movable plate After moving up, the steel rope can be stretched by the rotating block to move up. If the pressure plate rotates left and right, the rotating block can rotate on the mounting block. If the pressure plate rotates forward and backward, the length of the steel rope changes, so that the steel rope can be wound or unwound on the rotating ring, and the steel rope can be pulled to rotate the rotating ring after moving, so that the rotating shaft rotates. Regardless of the rotation direction of the pressure plate, the rotating shaft can be driven to rotate, so that the cam can be driven to rotate, so that the cam pushes the connecting plate to move down, so that the rubber plate and the chassis are fitted, and after the cam rotates, a downward pressure is applied to the rubber plate, so that the rubber plate is deformed, and the metal sheet is deformed by pushing the connecting plate downward, so that a downward pressure perpendicular to the chassis can be provided on the inclined chassis, thereby increasing the friction between the pressure plate and the chassis, so that the pressure plate is not easy to move, and then when the compression test is performed on the suspension on the chassis, the pressure plate is tilted together after the chassis is tilted, and the pressure plate is not easy to shift after tilting, and the fixed position of the pressure plate will not change, so as to avoid displacement of the chassis and uneven pressure on the pressure plate to affect the test accuracy, thereby improving practicality; 2. When the chassis moves to the base, the center of the wheel is aligned with the two sets of rubber blocks, and then the electric push rod can be started to drive the positioning sleeve to move down, so that the bottom of the positioning sleeve fits with the top of the tire, and after fitting, the electric push rod can continue to extend, so that the movable frame can be driven to move up, and then the baffle can slide in the movable groove, and then the hand wheel can be turned to drive the screw to rotate, and after the screw rotates, the rubber block is driven to move and fit with the wheel axis, so that the wheel axis is clamped and positioned. When the chassis is subjected to a certain pressure test, it will compress the tire and cause the tire to deform to a certain extent. After the tire is deformed, the wheel axis will drop, and then the rubber block can be driven to move down, so that the movable frame moves down, so that the positioning sleeve can always cover the top of the tire, which can improve the fixing effect of the chassis and improve practicality; 3. When performing compression test on the suspension at different positions on the chassis, the first motor can be started to drive the transverse threaded rod to rotate. After the transverse threaded rod rotates, it can drive the movable seat on one side to move. After the movable seat moves, it drives the movable frame to move. During the movement, the movable frame drives the movable seat on the other side to slide on the limit rod, and limits the movement of the movable frame, so that the left and right positions of the test can be adjusted. After that, the second motor can be started to drive the longitudinal threaded rod to rotate, so that the movable seat can be driven to move. During the movement, the movable seat can slide on the positioning rod to position the movement of the movable seat, so that the front and rear positions of the test can be adjusted, thereby facilitating the staff to adjust the test position and improving practicality.

Regardless of the rotation direction of the ball 207, one of the mounting rods 211 can be driven to tilt upward, and then the ball 212 can be pushed The movable plate 213 moves upward, so that the movable plate 213 slides on the support rod 214 and compresses the telescopic spring 215. After the movable plate 213 moves upward, the steel rope 219 can be stretched by the rotating block 218 to move upward. If the pressing plate 208 rotates left and right, the rotating block 218 can rotate on the mounting block 217. If the pressing plate 208 rotates forward and backward, the length of the steel rope 219 changes, so that the steel rope 219 can be wound or unwound on the rotating ring 222. After the steel rope 219 moves, the rotating ring 222 can be pulled to rotate, so that the rotating shaft 221 rotates. Regardless of the rotation direction of the pressing plate 208, the rotating shaft 221 can be driven to rotate, so that the cam 227 can be driven to rotate, so that the cam 227 pushes the connecting plate 224 downward, so that the rubber plate 230 is fitted with the chassis, and after the cam 227 rotates, a downward pressure is applied to the rubber plate 230, so that the rubber plate 230 is deformed, and the connecting plate 224 is pushed downward to drive the metal sheet 231 to deform, so that a downward pressure perpendicular to the chassis can be provided on the inclined chassis, thereby increasing the friction between the pressing plate 208 and the chassis, so that the pressing plate 208 is not easy to move; When the chassis moves to the base 1, the center of the wheel is aligned with the two groups of rubber blocks 307, and then the electric push rod 308 can be started to drive the positioning sleeve 309 to move downward, so that the bottom of the positioning sleeve 309 fits with the top of the tire, and after fitting, the electric push rod 308 can continue to extend, so that the movable frame 304 can be driven to move upward, so that the baffle 303 slides in the movable groove 302, and then the hand wheel 306 can be turned to drive the screw rod 305 to rotate, and after the screw 305 rotates, it drives the rubber block 307 to move and fit with the wheel axis, so that the wheel axis is clamped and positioned. When the chassis is subjected to a compression test, it will be compressed by a certain pressure, causing the tire to have a certain deformation. After the tire is deformed, the wheel axis will drop, and then the rubber block 307 can be driven to move downward, so that the movable frame 304 moves downward, so that the positioning sleeve 309 can always cover the wheel. The top of the tire can enhance the fixing effect of the chassis. When the suspension at different positions on the chassis is subjected to a compression test, the first motor 4021 can be started to drive the transverse threaded rod 402 to rotate. After the transverse threaded rod 402 rotates, it can drive the movable seat 403 on one side to move. After the movable seat 403 moves, it drives the movable frame 101 to move, and the movable frame 101 drives the movable seat 403 on the other side to slide on the limiting rod 4031 during the movement, and limits the movement of the movable frame 101, so that the left and right positions of the test can be adjusted. After that, the second motor 406 can be started to drive the longitudinal threaded rod 404 to rotate, so that the movable seat 405 can be driven to move. The movable seat 405 can slide on the positioning rod 407 during the movement, and the movement of the movable seat 405 is positioned, so that the front and rear positions of the test can be adjusted, thereby facilitating the staff to adjust the test position.

9. A method for testing a new energy vehicle chassis compression test device, using a new energy vehicle chassis compression test device as described in any one of claims 1 to 8, characterized in that: The test method steps are as follows: Step 1: When the new energy vehicle chassis is subjected to a compression test, the chassis is provided with four wheels, and the chassis can be moved to the top of the base (1). Then, the position of the mounting plate (201) is adjusted by the adjusting component (4). When each suspension on the chassis is subjected to a compression test, the hydraulic cylinder (203) is extended to drive the movable plate (204) to move downward. During the downward movement, the movable plate (204) drives the guide rod (205) to slide on the positioning block (206), and the movement of the movable plate (204) is limited, so that the pressure plate (208) contacts the chassis. Then, pressure is applied to the chassis by the hydraulic cylinder (203). After a suspension on the chassis is subjected to pressure, the suspension will shrink, while the other three suspensions will slightly contract. The pressure plate (208) can be tightly fitted with the chassis after the chassis is tilted, and the pressure plate (208) can rotate together with the tilt of the chassis, so that the spherical member (207) can be driven to rotate on the movable plate (204). After the spherical member (207) rotates, the swing rod (210) can be driven to rotate. Regardless of the rotation direction of the spherical member (207), one of the mounting rods (211) can be driven to tilt upward, and the moving plate (213) can be pushed upward by the ball bearing (212), so that the moving plate (213) slides on the support rod (214) and compresses the telescopic spring (215). After the moving plate (213) moves upward, the rotating block (2 18) The steel rope (219) is stretched to move upward. If the pressing plate (208) is rotated left and right, the rotating block (218) can be rotated on the mounting block (217). If the pressing plate (208) is rotated forward and backward, the length of the steel rope (219) changes, so that the steel rope (219) can be wound or unwound on the rotating ring (222). After the steel rope (219) moves, the rotating ring (222) can be pulled to rotate, so that the rotating shaft (221) rotates. Regardless of the rotation direction of the pressing plate (208), the rotating shaft (221) can be driven to rotate, so that the cam (227) can be driven to rotate, so that the cam (227) pushes the connecting plate (224) to move downward, so that the rubber plate (230) is fitted with the chassis. After the cam (227) rotates, it applies downward pressure to the rubber plate (230), causing the rubber plate (230) to deform, and pushes the connecting plate (224) downward to drive the metal plate (231) to deform, so that downward pressure perpendicular to the chassis can be provided on the inclined chassis, thereby increasing the friction between the pressing plate (208) and the chassis, making it difficult for the pressing plate (208) to move. When the pressure resistance test is performed on the suspension part of the chassis, the pressing plate (208) is tilted together with the chassis after the chassis tilts, and the pressing plate (208) is not easy to shift after the tilting, so that the fixed position of the pressing plate (208) will not change, thereby avoiding displacement of the chassis, avoiding uneven pressure on the pressing plate (208) to affect the test accuracy, and improving practicality. Step 2: When the chassis moves onto the base (1), the center of the wheel is aligned with the two sets of rubber blocks (307), and then the electric push rod (308) can be started to drive the positioning sleeve (309) to move downward, so that the bottom of the positioning sleeve (309) fits with the top of the tire, and after the fit, the electric push rod (308) can continue to extend, so that the moving frame (304) can be driven to move upward, thereby making the baffle (303) slide in the movable groove (302), and then the hand wheel (306) can be turned to drive the screw rod (305) The screw rod (305) rotates, and after the screw rod (305) rotates, the rubber block (307) is driven to move and fit with the wheel axis, so that the wheel axis is clamped and positioned. When the chassis is subjected to a compression test, the tire is compressed by a certain pressure, so that the tire is deformed to a certain extent. After the tire is deformed, the wheel axis will drop, and then the rubber block (307) can be driven to move downward, so that the moving frame (304) moves downward, so that the positioning sleeve (309) can always cover the top of the tire, which can improve the fixing effect of the chassis and improve the practicality. Step 3: When performing a compression test on the suspension at different positions on the chassis, the first motor (4021) can be started to drive the transverse threaded rod (402) to rotate. After the transverse threaded rod (402) rotates, it can drive the movable seat (403) on one side to move. After the movable seat (403) moves, it drives the movable frame (101) to move. During the movement, the movable frame (101) drives the movable seat (403) on the other side to slide on the limit rod (4031) to limit the movement of the movable frame (101), so that the left and right positions of the test can be adjusted. After that, the second motor (406) can be started to drive the longitudinal threaded rod (404) to rotate, so that the movable seat (405) can be driven to move. During the movement, the movable seat (405) can slide on the positioning rod (407) to position the movement of the movable seat (405), so that the front and rear positions of the test can be adjusted, thereby facilitating the staff to adjust the test position and improving practicality.
