Description

Technical Field

[0001] This utility model belongs to the field of whole vehicle vibration testing technology, and specifically relates to a whole vehicle vibration fatigue testing fixture. Background Technology

[0002] To test the reliability of a car under different road conditions over a long period of time, a vibration test is usually required. This involves placing the entire vehicle on a vibration test bench, where it vibrates continuously under the excitation of the test bench. The test aims to identify problems in the car's design and components.

[0003] Existing whole vehicle vibration fatigue tests typically involve placing the vehicle under test on a vibration table, where the vehicle vibrates continuously under the excitation of the vibration table, thereby completing the vibration fatigue test on the vehicle under test.

[0004] However, in existing whole-vehicle vibration fatigue tests, the stability of a vehicle is generally weak when the vehicle is subjected to vibration fatigue testing on a vibration table. Currently, the vehicle is usually parked on the test table and the front and rear wheel hubs are limited and fixed. However, during the vibration test, the vehicle is prone to shifting with the vibration of the vibration table, which can cause the front and rear wheel hubs to disengage from the limiting device. This reduces the stability of the vehicle during the vibration fatigue test. Since the top surface of the vibration table is far from the ground, there is a certain safety hazard when the front and rear wheel hubs of the vehicle disengage from the limiting device, which can also affect the accuracy of the whole-vehicle vibration fatigue test. Utility Model Content

[0005] In view of the problems in the related technologies, this utility model proposes a whole vehicle vibration fatigue test fixture to overcome the above-mentioned technical problems existing in the existing related technologies.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0007] This utility model relates to a vehicle vibration fatigue testing fixture, comprising a test bench, an inclined platform fixedly connected to the right side surface of the test bench, a vehicle body mounted on the test bench, four sliding grooves formed on the upper surface of the test bench, and a vibration mechanism fixedly installed in each of the four sliding grooves. The vibration mechanism is used to drive the vehicle body to perform a vibration fatigue test. A vibration table is slidably connected in the sliding grooves, and a clamping mechanism is provided on the vibration table to restrict the vehicle body from moving forward or backward during the vibration fatigue test. A limit mechanism is provided on the vibration table to restrict the vehicle body from moving left or right during the vibration fatigue test.

[0008] Furthermore, the vibration mechanism includes a vibration device, which is fixedly installed on the bottom wall of the corresponding sliding groove. The vibration end of the vibration device is fixedly connected to the lower surface of the vibration table, and the vehicle body is provided with four wheels.

[0009] Furthermore, the clamping mechanism includes an electric push rod, the vibration table is hollow inside, the electric push rod is fixedly connected to the inner wall of the vibration table, the telescopic end of the electric push rod is fixedly connected to a rack, the lower surface of the rack is fixedly connected to the bottom wall of the vibration table, and the upper surface of the vibration table has two limiting grooves communicating with its interior.

[0010] Furthermore, a bidirectional threaded rod is rotatably connected between the inner walls of the front and rear sides of the vibration table. A gear is fixedly sleeved on the outer surface of the bidirectional threaded rod. The positioning clamps are threaded on both opposite threads of the bidirectional threaded rod. The two positioning clamps are arranged in a mirror image. The lower surfaces of the two positioning clamps are slidably connected to the bottom wall of the vibration table.

[0011] Furthermore, the two positioning clamps are slidably connected to the two limiting grooves, the upper surfaces of the two positioning clamps extend beyond the upper surface of the vibration table, protective rubber blocks are fixedly connected to the outer surfaces of the adjacent sides of the two positioning clamps, the rack is meshed with the gear, and the wheel is located between the corresponding two positioning clamps.

[0012] Furthermore, the limiting mechanism includes a support groove, which is formed on the upper surface of the vibration table and communicates with the interior of the vibration table. A limiting slider is slidably connected in the support groove, and the limiting sliders on the left and right sides are mirror images of each other. Two positioning springs are fixedly connected to the bottom wall of the vibration table. The lower surface of the limiting slider extends into the vibration table, and the lower surface of the limiting slider is fixedly connected to the upper ends of the two positioning springs.

[0013] Furthermore, a connecting block is fixedly connected to the end of the rack away from the electric actuator. The lower surface of the connecting block is slidably connected to the bottom wall of the vibration table. A connecting groove is formed on the lower surface of the limiting slider. The connecting groove extends out of the left and right outer surfaces of the limiting slider. The connecting groove is adapted to the rack and is slidably connected to the slide rail groove. A slide rail groove is formed on the outer surface of the limiting slider away from the electric actuator. The slide rail groove extends out of the lower surface of the limiting slider. The top wall of the slide rail groove is inclined. The connecting block is slidably connected to the top wall of the slide rail groove.

[0014] This utility model has the following beneficial effects:

[0015] 1. This utility model can simultaneously drive the clamping mechanism and the limiting mechanism to restrict the vehicle body by activating the electric actuator, ensuring the stability and safety of the vehicle body during the vibration fatigue test, avoiding displacement or deviation during the vibration fatigue test, ensuring the accuracy of the whole vehicle vibration fatigue test, and being more energy-efficient and efficient, thereby increasing the practicality and flexibility of the whole vehicle vibration fatigue test fixture.

[0016] 2. This utility model restricts the sliding blocks to slide out of the upper surface of the vibration table through the support groove until the upper surface of the restricting blocks contacts the outer surface of the wheels. The four restricting blocks cooperate to restrict the four wheels, thereby restricting the vehicle body and preventing it from moving in the left and right directions during the vibration fatigue test.

[0017] 3. This utility model uses two protective rubber blocks to move relative to each other, causing the two protective rubber blocks to contact the front and rear sides of the wheel, thereby clamping the wheel and preventing it from moving back and forth during the vibration fatigue test. This ensures the stability of the vehicle body during the test and guarantees the safety of the whole vehicle during the vibration fatigue test.

[0018] 4. By using rubber as the protective rubber block, this utility model can prevent the positioning clamp from scratching the wheel hub during the whole vehicle vibration fatigue test, thereby ensuring the practicality of the whole vehicle vibration fatigue test fixture.

[0019] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0030] The technical solutions of the utility model embodiments will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the utility model, and not all embodiments. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the utility model.

[0031] In the description of this utility model, it should be understood that the terms "opening", "upper", "lower", "top", "middle", "inner", etc., which indicate orientation or positional relationship, are only for the convenience of describing the utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the utility model.

[0032] Please see Figures 1-7 As shown, this utility model is a vehicle vibration fatigue test fixture, including a test bench 1. An inclined platform 2 is fixedly connected to the right surface of the test bench 1. A vehicle body 17 is arranged on the test bench 1. Four sliding grooves 3 are opened on the upper surface of the test bench 1. A vibration mechanism is fixedly installed in each of the four sliding grooves 3. The vibration mechanism is used to drive the vehicle body 17 to perform a vibration fatigue test. A vibration table 4 is slidably connected in the sliding grooves 3. A clamping mechanism is provided on the vibration table 4. The clamping mechanism is used to restrict the vehicle body 17 from moving back and forth during the vibration fatigue test. A limit mechanism is provided on the vibration table 4. The limit mechanism is used to restrict the vehicle body 17 from moving left and right during the vibration fatigue test.

[0033] In use, the vehicle body 17 is placed on the test bench 1 via the tilting platform 2, so that the four wheels 18 are located on the four vibration tables 4. At this time, the clamping mechanism is activated, which restricts the front and rear sides of the wheels 18, preventing the wheels 18 from moving forward or backward. Simultaneously, the clamping mechanism also drives the four limiting mechanisms to operate. The four limiting mechanisms work together to restrict the four wheels 18, preventing them from moving left or right. In summary, the clamping mechanism and the limiting mechanisms work together to restrict the vehicle body 17, preventing it from moving forward, backward, left, or right. The vibration mechanism can then drive the vehicle body 17 to undergo vibration fatigue testing.

[0034] In one embodiment, the vibration mechanism includes a vibration device 19, which is fixedly installed on the bottom wall of the corresponding sliding groove 3. The vibration end of the vibration device 19 is fixedly connected to the lower surface of the vibration table 4, and four wheels 18 are provided on the vehicle body 17.

[0035] Furthermore, in specific applications, when the vibration device 19 is activated, it drives the vibration table 4 to slide up and down within the sliding groove 3, thereby synchronously driving the vehicle body 17 located on the vibration table 4 to vibrate up and down, thus conducting vibration fatigue tests on the entire vehicle. The vibration device 19 includes a hydraulic pump station, high-pressure oil pipes, servo valves, actuator cylinders, actuator cylinder controllers, road spectrum collectors, power batteries, power battery simulators, acceleration sensors, temperature sensors, vehicle controllers, main control computers, strain gauges, and data acquisition systems. The vibration device 19, vehicle body 17, and wheels 18 are existing technologies in the publicly disclosed patent: CN201420038405.X, "A Vehicle Vibration Testing System for Electric Vehicles," which will not be elaborated upon here.

[0036] In one embodiment, the upper clamping mechanism includes an electric push rod 5, the vibration table 4 is hollow inside, the electric push rod 5 is fixedly connected to the inner wall of the vibration table 4, the telescopic end of the electric push rod 5 is fixedly connected to a rack 6, the lower surface of the rack 6 is fixedly connected to the bottom wall of the vibration table 4, and the upper surface of the vibration table 4 has two limiting grooves 13 that communicate with its interior.

[0037] A bidirectional threaded rod 7 is rotatably connected between the inner walls of the front and rear sides of the vibration table 4. A gear 8 is fixedly sleeved on the outer surface of the bidirectional threaded rod 7. The positioning clamp 9 is threadedly sleeved at the two opposite threads of the bidirectional threaded rod 7. The two positioning clamps 9 are arranged in a mirror image. The lower surfaces of the two positioning clamps 9 are slidably connected to the bottom wall of the vibration table 4.

[0038] The two positioning clamps 9 are slidably connected to the two limiting grooves 13. The upper surfaces of the two positioning clamps 9 extend out of the upper surface of the vibration table 4. Protective rubber blocks 10 are fixedly connected to the outer surfaces of the two adjacent sides of the two positioning clamps 9. The rack 6 is meshed with the gear 8. The wheel 18 is located between the corresponding two positioning clamps 9.

[0039] In addition, in specific applications, the vehicle body 17 is placed on the test bench 1 via the tilting platform 2, so that the four wheels 18 are located on the four vibration tables 4, and the two positioning clamps 9 are located on the front and rear sides of the corresponding wheels 18. At this time, the electric push rod 5 is activated, which drives the corresponding rack 6 to move left and right. During the left and right movement of the rack 6, it meshes with the gear 8, thereby synchronously driving the gear 8 and the double-threaded rod 7 to rotate. The rotation of the double-threaded rod 7 synchronously drives the corresponding two positioning clamps 9 to move in opposite or opposite directions. When the two positioning clamps 9 move relative to each other, they synchronously drive the two protective rubber blocks 10 to move relative to each other, thereby driving the two protective rubber blocks 10 to contact the front and rear sides of the wheels 18, thus clamping the wheels 18 and preventing them from moving in the front and rear directions during the vibration fatigue test. This ensures the stability of the vehicle body 17 during the test and thus guarantees the safety of the whole vehicle during the vibration fatigue test.

[0040] In one embodiment, for the upper limit mechanism, the limiting mechanism includes a support groove 20, which is formed on the upper surface of the vibration table 4 and communicates with the interior of the vibration table 4. A limiting slider 12 is slidably connected in the support groove 20, and the limiting sliders 12 on the left and right sides are mirror images of each other. Two positioning springs 11 are fixedly connected to the bottom wall of the vibration table 4. The lower surface of the limiting slider 12 extends into the vibration table 4, and the lower surface of the limiting slider 12 is fixedly connected to the upper ends of the two positioning springs 11.

[0041] A connecting block 14 is fixedly connected to one end of the rack 6 away from the electric push rod 5. The lower surface of the connecting block 14 is slidably connected to the bottom wall of the vibration table 4. A connecting groove 15 is provided on the lower surface of the limiting slider 12. The connecting groove 15 extends out of the left and right outer surfaces of the limiting slider 12. The connecting groove 15 is adapted to the rack 6. The connecting groove 15 is slidably connected to the slide rail groove 16. A slide rail groove 16 is provided on the outer surface of the limiting slider 12 away from the electric push rod 5. The slide rail groove 16 extends out of the lower surface of the limiting slider 12. The top wall of the slide rail groove 16 is inclined. The connecting block 14 is slidably connected to the top wall of the slide rail groove 16.

[0042] Furthermore, in specific applications, when the rack 6 moves left and right, it synchronously drives the connecting block 14 to move left and right. When the connecting block 14 moves towards the limiting slider 12, the connecting block 14 slides into the slide rail groove 16 and slides into the top wall of the slide rail groove 16. Because the top wall of the slide rail groove 16 is an inclined surface, when the connecting block 14 moves towards the limiting slider 12, the connecting block 14 drives the limiting slider 12 to move upward. During this process, the positioning spring 11 is simultaneously stretched and deformed. During this process, the limiting slider 12 is also simultaneously slid out of the upper surface of the vibration table 4 through the support groove 20 until the upper surface of the limiting slider 12 contacts the outer surface of the wheel 18. The four limiting sliders 12 cooperate to limit the four wheels 18, thereby limiting the vehicle body 17 and preventing it from moving left and right during the vibration fatigue test. This ensures the stability of the vehicle body 17 during the test and further guarantees the safety of the whole vehicle during the vibration fatigue test.

[0043] In addition, in specific applications, by activating the electric push rod 5, the clamping mechanism and the limiting mechanism can be driven simultaneously to restrict the vehicle body 17, ensuring the stability and safety of the vehicle body 17 during the vibration fatigue test, avoiding displacement or deviation during the vibration fatigue test, ensuring the accuracy of the whole vehicle vibration fatigue test, and being more energy-efficient and efficient, thereby increasing the practicality and flexibility of the whole vehicle vibration fatigue test fixture.

[0044] In addition, in specific applications, the protective rubber block 10 is made of rubber, which can prevent the positioning clamp 9 from scratching the wheel hub of the wheel 18 when the vehicle body 17 is subjected to whole vehicle vibration fatigue test, thereby ensuring the practicality of the whole vehicle vibration fatigue test fixture.

[0045] In summary, by means of the above-mentioned technical solution of this utility model, when the vibration device 19 is started, the vibration device 19 drives the vibration table 4 to slide up and down in the sliding groove 3, thereby synchronously driving the vehicle body 17 located on the vibration table 4 to vibrate up and down, thereby conducting a vibration fatigue test on the whole vehicle. When the electric push rod 5 is started, the electric push rod 5 drives the corresponding rack 6 to move left and right. During the left and right movement of the rack 6, it meshes with the gear 8, thereby synchronously driving the gear 8 and the double-threaded rod 7 to rotate. The rotation of the double-threaded rod 7 synchronously drives the two corresponding positioning clamps 9 to move in opposite or opposite directions. When the two positioning clamps 9 move relative to each other, they synchronously drive the two protective rubber blocks 10 to move relative to each other, thereby making the two protective rubber blocks 10 contact the front and rear sides of the wheel 18, thereby clamping the wheel 18. The rack 6 then moves... When the vehicle moves left and right, it synchronously drives the connecting block 14 to move left and right. When the connecting block 14 moves towards the limiting slider 12, the connecting block 14 slides into the slide rail groove 16 and slides to the top wall of the slide rail groove 16. Because the top wall of the slide rail groove 16 is an inclined surface, when the connecting block 14 moves towards the limiting slider 12, the connecting block 14 drives the limiting slider 12 to move upward. During this process, the positioning spring 11 is stretched and deformed. During this process, the limiting slider 12 is also driven to slide out of the upper surface of the vibration table 4 through the support groove 20 until the upper surface of the limiting slider 12 contacts the outer surface of the wheel 18. The four limiting sliders 12 cooperate to limit the four wheels 18, thereby limiting the vehicle body 17 and preventing it from moving left and right during the vibration fatigue test.

[0046] Through the above technical solution, 1. by activating the electric push rod 5, the clamping mechanism and the limiting mechanism can be driven simultaneously to restrict the vehicle body 17, ensuring the stability and safety of the vehicle body 17 during the vibration fatigue test, avoiding displacement or deviation during the vibration fatigue test, ensuring the accuracy of the whole vehicle vibration fatigue test, and being more energy-efficient and efficient, thereby increasing the practicality and flexibility of the whole vehicle vibration fatigue test fixture.

[0047] 2. The limiting slider 12 slides out of the upper surface of the vibration table 4 through the support groove 20 until the upper surface of the limiting slider 12 contacts the outer surface of the wheel 18. The four limiting sliders 12 cooperate with each other to limit the four wheels 18, thereby limiting the vehicle body 17 so that it will not move in the left and right directions during the vibration fatigue test.

[0048] 3. By moving the two protective rubber blocks 10 relative to each other, the two protective rubber blocks 10 come into contact with the front and rear sides of the wheel 18, thereby clamping the wheel 18 so that it will not move in the front and rear direction during the vibration fatigue test, ensuring the stability of the vehicle body 17 during the test, and thus ensuring the safety of the whole vehicle during the vibration fatigue test.

[0049] 4. By using rubber to protect the rubber block 10, the positioning clamp 9 can be prevented from scratching the wheel hub of the wheel 18 during the whole vehicle vibration fatigue test, thus ensuring the practicality of the whole vehicle vibration fatigue test fixture.
