Specific embodiments

[0025] To make the objectives, technical solutions, and advantages of the embodiments of the present utility model clearer, the technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Apparently, the described embodiments are some, but not all, of the embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0026] As Figure 1 and Figure 2 shown, an automobile shock-absorption simulation device includes a shock-absorbing support plate 1, a main body vibration simulation component 2, a segmented vibration simulation component 3, and a bump climbing simulation component 4. The main body vibration simulation component 2 is disposed at the bottom of the shock-absorbing support plate 1. The segmented vibration simulation component 3 is detachably disposed on the top of the shock-absorbing support plate 1. The bump climbing simulation component 4 is oppositely disposed on both sides of the shock-absorbing support plate 1, and both bump climbing simulation components 4 on both sides are rotatably connected to the shock-absorbing support plate 1.

[0027] As Figure 3As shown, the main body vibration simulation component 2 includes a vibration support base 21, a vibration generator 22, a lifting vibration groove 23, a vibration support shaft 24, a lifting limit block 25, and a support spring 26. The middle part of the vibration support base 21 is in a groove shape. The vibration generator 22 is arranged in the groove of the vibration support base 21. An internal lifting vibration groove 23 is provided in the vibration generator 22. The vibration support shaft 24 is slidably arranged in the lifting vibration groove 23. The lifting limit block 25 is arranged at the lower end of the vibration support shaft 24. The support spring 26 is sleeved on the outer walls of the vibration generator 22 and the vibration support shaft 24. The support spring 26 is arranged between the bottom of the groove of the vibration support base 21 and the shock absorption support plate 1.

[0028] As Figure 4 As shown, the main body vibration simulation component 2 further includes an auxiliary vibration groove 27, an auxiliary vibration pillar 28, and an auxiliary vibration spring 29. A plurality of the auxiliary vibration grooves 27 are arranged on both side edges of the vibration support base 21. The auxiliary vibration grooves 27 are on the same side as the bump climbing simulation component 4. A plurality of the auxiliary vibration pillars 28 are slidably arranged in the plurality of the auxiliary vibration grooves 27 one by one. A plurality of the auxiliary vibration springs 29 are sleeved on the outer walls of the plurality of the auxiliary vibration pillars 28 one by one. The plurality of the auxiliary vibration springs 29 are arranged between the top of the side edge of the vibration support base 21 and the shock absorption support plate 1.

[0029] The vibration support shaft 24 slides up and down in the lifting vibration groove 23 inside the vibration generator 22. When moving upward, the lifting limit block 25 installed on the vibration support shaft 24 is used for limiting to prevent the vibration support shaft 24 from detaching from the vibration generator 22. Therefore, the vibration support shaft 24 forms a clamping structure with the vibration generator 22 through the lifting limit block 25, and the vibration support shaft 24 forms a lifting structure with the vibration support base 21 through the vibration generator 22. The vibration generator 22 inside the vibration support base 21 drives the vibration support shaft 24 to lift along the lifting vibration groove 23, thereby generating an effect of simulating vibration. Cooperating with the segmented vibration simulation component 3 at the top for simulation from all aspects, when the lifting limit block 25 on the outer wall of the vibration support shaft 24 slides in the lifting vibration groove 23, it also limits the sliding range of the vibration support shaft 24. The outside of the vibration generator 22 is elastically supported by the support spring 26, and the auxiliary vibration pillars 28 at the top of the side edge of the vibration support base 21 cooperate with the auxiliary vibration springs 29 for auxiliary support and simulating vibration. The auxiliary vibration pillars 28 lift along the auxiliary vibration grooves 27 to strengthen the simulation effect and improve the support effect, thereby extending the service life of the device.

[0030] The block vibration simulation component 3 includes an automotive test partition plate 31, block vibration springs 32, a block vibration support plate 33, and automotive side protection plates 34. The automotive test partition plate 31 is detachably arranged on the top of the shock absorption support plate 1. The block vibration support plate 33 is arranged on the top of the automotive test partition plate 31. The block vibration springs 32 are arranged between the automotive test partition plate 31 and the block vibration support plate 33. The automotive side protection plates 34 are oppositely arranged on both sides of the automotive test partition plate 31, and the automotive side protection plates 34 are arranged on the two adjacent sides to the bump climbing simulation component 4.

[0031] The block vibration simulation component 3 further includes snap-in mounting blocks 35 and mounting snap-in grooves 39. A plurality of the snap-in mounting blocks 35 are arranged at the bottom of the automotive test partition plate 31. The mounting snap-in grooves 39 are arranged at the top of the shock absorption support plate 1. The snap-in mounting blocks 35 and the mounting snap-in grooves 39 cooperate with each other to achieve detachable connection.

[0032] As Figure 5 shown, the block vibration simulation component 3 further includes ball contraction grooves 36, ball limiting springs 37, and snap-in balls 38. A plurality of the ball contraction grooves 36 are arranged on the snap-in mounting blocks 35. One end of each of a plurality of the ball limiting springs 37 is respectively arranged at the bottom of a corresponding one of the plurality of ball contraction grooves 36 one by one. A plurality of the snap-in balls 38 are respectively arranged at the other end of a corresponding one of the plurality of ball limiting springs 37 one by one. The ball limiting springs 37 and the snap-in balls 38 are telescopic within the ball contraction grooves 36.

[0033] The block vibration support plate 33 and the automotive test partition plate 31 form an elastic structure through the block vibration springs 32. The block vibration springs 32 are composed of springs with different sizes and various elasticities unevenly distributed, simulating the situation when an automobile enters a pitted and uneven ground. The automotive test partition plate 31 and the mounting snap-in grooves 39 form a snap-in structure through the snap-in mounting blocks 35. The block vibration support plate 33 on the automotive test partition plate 31 vibrates in cooperation with the block vibration springs 32 at the bottom, so as to achieve shock absorption simulation when vibrations occur in different areas. And through the automotive side protection plates 34 on both sides, it is prevented that the automobile accidentally slides off. When subsequent maintenance and replacement are required, the automotive test partition plate 31 is pulled out along the mounting snap-in grooves 39 through the snap-in mounting blocks 35 at the bottom, so that the snap-in balls 38 on both sides of the snap-in mounting blocks 35 contract into the ball contraction grooves 36, pressing the ball limiting springs 37 to disengage from the snap-in connection with the mounting snap-in grooves 39, thereby facilitating disassembly and repair.

[0034] The bump climbing simulation component 4 includes an automotive climbing plate 41 and bump simulation patterns 42. The automotive climbing plate 41 is rotatably connected to the side of the shock absorption support plate 1. The bump simulation patterns 42 are arranged on the top surface of the automotive climbing plate 41.

[0035] The bump climbing simulation component 4 further includes a climbing board adjusting rotating shaft 43 and a rotating fixed rotating groove 44. The climbing board adjusting rotating shaft 43 is arranged on the side edge of the vehicle climbing board 41 close to the shock absorption support plate 1, and the rotating fixed rotating groove 44 is arranged on the side edge of the shock absorption support plate 1 close to the vehicle climbing board 41. The climbing board adjusting rotating shaft 43 and the rotating fixed rotating groove 44 cooperate with each other to achieve a rotating connection.

[0036] Working principle: First, the vehicle climbs upward through the bump climbing simulation component 4. When driving to the bump simulation pattern 42 on the vehicle climbing board 41, the bump situation of the vehicle during operation is simulated through the bump simulation pattern 42. And since the vehicle presses down on the vehicle climbing board 41 due to gravity, the shock absorption support plate 1 as a whole moves downward due to the main body vibration simulation component 2. As the vehicle climbs higher, the distance from the main body vibration simulation component 2 is closer and the gravity it bears is greater. The shock absorption support plate 1 and the connected vehicle climbing board 41 will move downward under the action of gravity, and the angle between the shock absorption support plate 1 and the connected vehicle climbing board 41 changes continuously. The climbing board adjusting rotating shaft 43 on the side of the vehicle climbing board 41 rotates along the rotating fixed rotating groove 44, so as to cooperate with the shock absorption support plate 1 and the vehicle climbing board 41 to adjust the angle to adapt to the climbing situation. After the vehicle moves onto the segmented vibration simulation component 3, the segmented vibration support plate 33 on the vehicle test partition plate 31 vibrates in cooperation with the segmented vibration spring 32 at the bottom, so as to achieve the shock absorption detection when vibrations occur in different areas. And through the vehicle side protection plates 34 on both sides, it is prevented that the vehicle accidentally slips. When subsequent maintenance and replacement are required, the vehicle test partition plate 31 is pulled out along the installation engagement groove 39 through the engagement installation block 35 at the bottom, so that the engagement beads 38 on both sides of the engagement installation block 35 contract into the bead contraction groove 36, pressing the bead limit spring 37 to disengage from the engagement with the installation engagement groove 39, thus facilitating disassembly and repair.

[0037] Secondly, for the main body vibration simulation component 2 at the bottom of the shock absorption support plate 1, the vibration generator 22 inside the vibration support base 21 drives the vibration support shaft 24 to move up and down along the lifting vibration groove 23, so as to produce the effect of simulating vibration, and cooperate with the segmented vibration simulation component 3 on the top to simulate from all aspects. When the lifting limit block 25 on the outer wall of the vibration support shaft 24 slides in the lifting vibration groove 23, it also limits the sliding range of the vibration support shaft 24. The outside of the vibration generator 22 is elastically supported by the support spring 26, and the auxiliary vibration support column 28 on the top of the vibration support base 21 cooperates with the auxiliary vibration spring 29 to assist in supporting and simulating vibration. The auxiliary vibration support column 28 moves up and down along the auxiliary vibration groove 27 to strengthen the simulation effect and improve the support effect, thereby extending the service life of the device.

[0038] The material of the vibration support base 21 is foam aluminum alloy.
