[0002] With the rapid development of my country's electric vehicle industry, the production and sales of electric vehicles are growing rapidly, and the electrical safety of electric vehicles has attracted more and more attention. The battery pack of electric vehicles is affected by external forces such as impact and extrusion, which causes the battery pack shell to deform, leading to internal thermal runaway and causing new energy vehicles to catch fire. It is very necessary to test the extreme anti-extrusion and anti-deformation capabilities of power batteries.

[0003] When an electric vehicle has an accident during driving, the speed and weight of the vehicle body are different, and the collision energy is also different. In order to simulate the impact performance of different speeds and masses on the power battery during the test, the test equipment needs to have the ability to adjust the speed and weight step by step to meet the verification requirements for product safety performance.

[0004] At present, the electric linear impact equipment used for power battery impact test is composed of electromagnetic launch system, launcher, guide moving frame, brake mechanism, etc. The existing equipment impact method is to fix the impact block on the guide moving frame, and the guide moving frame impacts the fixed sample along the linear guide rail. Because the distance of the linear guide rail is short and there is an upper limit requirement for the impact energy, excessive weight can easily cause deformation and damage of the linear guide rail and slider, and the guide rail and slider often need to be replaced, with high maintenance frequency, long cycle and high cost.

The lateral adjustment member 64 is used to drive the front end mounting plate 63 and the impactor 5 to move along the width direction of the mobile trolley 1. The height adjustment member 65 is used to allow the front end mounting plate 63 and the impactor 5 to move along the height direction of the mobile trolley 1. The setting of the mounting frame 61 makes it difficult to damage the trolley body 11 during the impact test.

[0040] Furthermore, there are multiple configuration plates 3 , and the multiple configuration plates 3 are arranged along the length direction of the moving trolley 1 .

[0041] The implementation details of this embodiment are described in detail below. The following content is only provided for easy understanding of the implementation details and is not necessary for implementing this solution.

[0042] Further, such as Figure 1 , Figure 2 , Figure 3As shown, the middle mounting plate 62 is provided with a transverse long slot 66 extending along the width direction of the mobile trolley 1, and the front mounting plate 63 has a transverse mounting hole 630. The transverse adjustment member 64 has a transverse adjustment section embedded in the transverse long slot 66, and a transverse positioning section 642 connected to the transverse adjustment section and extending to the front mounting plate 63. The transverse adjustment section is used to slide along the extension direction of the transverse long slot 66, and the transverse positioning section 642 is inserted into the transverse mounting hole 630 and fixed to the front mounting plate 63, and the transverse positioning section 642 will not move up, down, left, and right along the front mounting plate 63. The transverse positioning section 642 is inserted into the transverse mounting hole 630 to drive the front mounting plate 63 to move along the transverse long slot 66, so that the impactor 5 can be moved laterally to a suitable position. Adjust the transverse direction position of the middle mounting plate and fix it to the mounting frame.

[0043] Further, such as Figure 1 , Figure 2 , Figure 3 As shown, there are four transverse mounting holes 630 respectively opened at the four corner ends of the front mounting plate 63; the impactor 5 is located between the four transverse mounting holes. There are four transverse adjustment members 64 and four transverse long slots 66, and the transverse adjustment members 64 and the transverse long slots 66 are arranged one by one with the transverse mounting holes 630. Thus, the transverse mounting holes 630 can carry the impactor 5 to move stably transversely, and the transverse movement is to move in a direction perpendicular to the track, which is also the width direction of the mobile trolley 1.

[0044] In addition, if Figure 1 , Figure 2 , Figure 3 As shown, the front mounting plate 63 is provided with a height slot 67 extending in the height direction of the mobile trolley 1, and the middle mounting plate 62 has a height mounting hole 620. The height adjusting member 65 has a height adjusting section 651 embedded in the height slot 67, and a height positioning section 652 connected to the height adjusting section 651 and extending into the middle mounting plate 62. The height adjusting section 651 is used to slide along the extending direction of the height slot 67, and the height positioning section 652 is inserted into the height mounting hole 620 and fixed to the middle mounting plate 62, and the height positioning section 652 will not slide up and down or left and right along the middle mounting plate 62. The height positioning section 652 is inserted into the height mounting hole 620, and the front mounting plate 63 can slide up and down in the height direction, and the height adjusting section 651 is always embedded in the height slot 67, and is locked with the bottom of the height slot 67, and will not fall off from the height slot 67. The height position of the front mounting plate 63 is adjusted and fixedly connected to the middle mounting plate.

[0045] Furthermore, there are two height slots 67, which are arranged opposite to each other along the width direction of the mobile trolley 1, and the impactor 5 is arranged between the two height slots 67. There are two height adjustment members 65 and two height mounting holes 620, and the height adjustment members 65 and the height mounting holes 620 are arranged one-to-one with the height slots 67.

[0046] Further, such as Figure 1 , Figure 2 , Figure 3 As shown, a plurality of functional holes 21 are provided on the reinforcing plate 2, and the functional holes 21 are used to install counterweights and reduce weight. Thus, the reinforcing plate 2 is added to make the trolley body 11 more solid and prolong the service life, and the mobile trolley 1 will not be too heavy, and the equipment in this embodiment can also be used for small mass tests in large masses. In addition, the functional holes 21 are provided to control the mass required for the test. In large mass impact tests, accessories can be installed or reduced on the functional holes 21, or accessories can be installed or reduced on the configuration plate 3, or even the configuration plate 3 can be installed or reduced to adjust the mass of the mobile trolley 1. The mobile trolley 1 can have more mass types to meet different large mass test requirements.

[0047] In addition, if Figure 1 , Figure 2 , Figure 3 As shown, the middle mounting plate 62 is connected to the mounting frame 61 by fixing bolts 68 to fix the middle mounting plate 62 to the mounting frame 61. The mounting frame 61 is welded to the trolley body 11 to make the mobile trolley 1 more secure. The top surface of the front end of the trolley body 11 has a top eave 14 extending toward the direction of the sample to be tested, and the bottom surface of the front end of the trolley body 11 has a bottom eave 15 extending toward the direction of the sample to be tested; the top eave 14 and the bottom eave 15 are spaced apart to form a mounting cavity 13 for accommodating the mounting frame 61. This makes the mobile trolley 1 stronger and more secure, the front end of the trolley body 11 is not easily damaged, and the impactor 5 is more stable during the collision.

[0048] In addition, if Figure 1 , Figure 2 , Figure 3 As shown, the middle mounting plate 62 is located outside the mounting cavity 13 and conflicts with the top eaves 14 and the bottom eaves 15. This makes the mobile trolley 1 stronger, and in the impact test, the impactor 5 can also impact stably without causing inaccurate testing due to excessive impact force and displacement of the impactor 5.

[0049] Further, such as Figure 4 , Figure 5As shown, the mobile trolley 1 has a length support beam 16 and a width support beam 17 arranged on the bottom surface of the trolley body 11.

The width support beam 17 extends along the width direction of the mobile trolley 1, and the two ends of the length support beam 16 are respectively connected to the side of the trolley body 11 and the length support beam 16. The front guide wheel 12 and the rear guide wheel 12 have the same structure, and one is taken as an example. Each guide wheel 12 includes: a wheel frame 121 connecting the width support beam 17 and the trolley body 11, a wheel axle 122 connected to the wheel frame 121, and a wheel body 123 connected to the wheel axle 122. The arrangement of the length support beam 16 and the width support beam 17 makes the mobile trolley 1 stronger and more solid, and is not easily damaged in the impact test, thereby extending the service life.

[0050] like Figure 4 , Figure 5 As shown, each wheel frame 121 is convex toward the top surface of the trolley body 11 to form an arch, and the wheel frame 121 has an arched belly middle section 1210. The wheel frame 121 is at least partially widened from the end side toward the belly middle section 1210, and the wheel axle 122 is connected to the belly middle section 1210. In other words, the width of the belly middle section 1210 is relatively large, and the width of the belly middle section 1210 is the dimension of the belly middle section 1210 extending toward the trolley body 11. By setting the arched structure of the wheel frame 121 and cooperating with the width support beam 17, the wheel frame 121 is more solid and has greater strength, which prevents the mobile trolley 1 from tilting or turning up during the collision, and then the impact force is large when descending, causing the wheel frame 121 to break. In addition, each guide wheel 12 is independently arranged, and the wheel axle 122 is not shared with each other, which further strengthens the strength of the guide wheel 12 and is easy to install.

[0051] In addition, if Figure 4 , Figure 5 As shown, each wheel frame 121 has a pair of support plates 1211 relatively spaced apart along the width direction of the mobile trolley 1, and a pair of connecting plates 1212 relatively spaced apart along the length direction of the mobile trolley 1, the connecting plates 1212 connecting the pair of support plates 1211, and the pair of connecting plates 1212 are respectively fixedly connected to the trolley body 11 and the width support beam 17. The wheel axle 122 connects the pair of support plates 1211, and the wheel body 123 is located between the pair of support plates 1211.

[0052] Further, such as Figure 4 , Figure 5 As shown, a support protrusion 18 is provided on the width support beam 17 , and the support protrusion 18 is connected to the connecting plate 1212 .

[0053] Further, such as Figure 4 , Figure 5As shown, each support plate 1211 is convex toward the top surface of the trolley body 11 to form an arch, and the support plate 1211 has an arched belly middle section 1210. The belly middle section 1210 is arranged opposite to the end surface of the wheel body 123, and the axis of the wheel axle 122 is collinear with the midline of the length direction of the support plate 1211.

[0054] Further, such as Figure 4 , Figure 5 As shown, the top 1213 of the abdominal middle section 1210 is lower than the top 1230 of the wheel body 123. The ratio of the distance between the top 1213 of the abdominal middle section 1210 and the top 1230 of the wheel body 123 to the distance between the top 1213 of the abdominal middle section 1210 and the axis of the wheel body 123 is 2:3-4:5.

[0055] Further, such as Figure 4 , Figure 5 As shown, the support plate 1211 has a pair of connecting sections 1214 connected to the middle section 1210 of the abdomen, and the middle section 1210 of the abdomen is respectively located between the pair of connecting sections 1214. The connecting plate 1212 is connected to the connecting section 1214, and the portion where the connecting section 1214 is connected to the connecting plate 1212 gradually bulges from the end to the middle section 1210 of the abdomen in a direction away from the trolley body 11, further increasing the strength.

[0056] In addition, if Figure 4 , Figure 5 As shown, each wheel frame 121 is connected to a different width support beam 17, and a pair of guide wheels 12 located at the front side of the trolley body 11 are separated by a length support beam 16, and a pair of guide wheels 12 located at the rear side of the trolley body 11 are separated by a length support beam 16. The wheel frame 121 located at the front side of the trolley body 11 is connected to the front end of the trolley body 11, and the wheel frame 121 located at the rear side of the trolley body 11 is connected to the rear end of the trolley body 11.
