Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of new energy battery detection, in particular to a new energy battery pack impact resistance detection device. BACKGROUND

[0002] In recent years, with the rapid growth of electric vehicles and hybrid electric vehicles, the safety and reliability of power batteries as core energy storage components are crucial. Before the battery is shipped, it must undergo strict impact resistance testing to ensure its structural integrity and performance stability under vehicle driving, collision or other extreme working conditions.

[0003] Currently, most battery impact testing devices on the market use fixed impact structures and can only apply impact loads to a single angle (such as the vertical direction) of the battery. However, in actual use, the battery may face impacts from different directions, such as vehicle collisions, bumpy roads or accidental drops, etc. The existing testing devices cannot simulate multi-angle impact environments, resulting in deviations between test results and actual application scenarios, making it difficult to comprehensively evaluate the impact resistance performance of the battery.

[0004] Therefore, it is urgent to develop a new battery pack impact resistance detection device that can achieve multi-angle and multi-directional impact testing to more realistically simulate the impact loads that the battery may receive in actual use, thereby improving the accuracy and reliability of the test and providing more comprehensive data support for battery safety design.

[0005] Patent document publication number CN216349471U discloses a battery multi-angle impact testing device, which includes a first vertical plate, a first reinforcing horizontal rod and a first reinforcing vertical rod are fixedly connected in the first vertical plate, a second vertical plate, a second reinforcing horizontal rod and a second reinforcing vertical rod are fixedly connected in the second vertical plate, and a bottom plate is fixedly connected with the bottom of the first vertical plate and the second vertical plate.

[0006] The test device can change the angle of the battery relative to the horizontal plane by adjusting the angle between the support plate and the bottom plate, thereby achieving impact test of the battery at different angles. In this way, the impact response of the battery under external force at different installation angles can be simulated. However, the current test device has certain limitations: although it can adjust the angle between the battery and the horizontal plane to simulate the impact force in the vertical direction, in actual application, the use environment of the battery is usually accompanied by impact force from the horizontal direction. Therefore, the existing test device fails to fully consider this horizontal impact force. During the force process of the battery, the horizontal impact may not only cause deformation of the battery shell, but also cause damage to the internal structure, such as contact problems of the battery electrode, damage to the separator, etc., which may occur in the actual use and transportation of the battery. In actual accident situations (such as vehicle falling or collision), the battery pack will usually experience a complex force trajectory. In addition to being subjected to horizontal impact, the deformation of the vehicle frame will also cause the battery to be subjected to vertical impact, and the vertical and horizontal impacts may overlap and act on the battery pack. This composite impact process cannot be fully simulated by a single direction of vertical or horizontal test. SUMMARY

DETAILED DESCRIPTION

[0035] In order to further understand the features, technical means and specific purposes and functions achieved by the present application, the present application will be described in further detail below in conjunction with the drawings and specific embodiments.

[0036] As shown in Figure 1 , Figure 2 and Figure 3 , a new energy battery pack 7 impact detection device, comprising a base 11 and a falling table 2 freely falling on the top of the base 11, also comprising a sliding table 3, an inclined table 4 and a transverse impact generator; the sliding table 3 is horizontally arranged on the top of the falling table 2, and the sliding table 3 can move relative to the falling table 2 along the horizontal direction; the inclined table 4 is arranged on the top of the sliding table 3 and is hinged thereto, the inclined table 4 can rotate around at least one horizontal axis to adjust the inclination angle, and can be inclined relative to the sliding table 3 along the vertical direction; the battery pack 7 is fixedly arranged on the top of the inclined table 4; the transverse impact generator comprises an impact executor 51 and an impact trigger 52, the impact executor 51 is arranged on the bottom of the sliding table 3 and extends downward through the falling table 2, the impact trigger 52 is arranged on the base 11 and located at the bottom of the falling table 2, when the falling table 2 freely falls to the preset position, the impact executor 51 collides with the impact trigger 52, and the sliding table 3 generates instantaneous impact relative to the falling table 2 along the horizontal direction; an inertial force sensor is arranged on the sliding table.

[0037] The top of the base 11 is provided with a stand column and a top table 12 arranged at the top end of the stand column, the top table 12 is provided with a roller 121, the top of the falling table 2 is provided with a gantry 21, one side of the base 11 is provided with a winch 13, the steel wire rope on the winch 13 extends upward, crosses over the roller 121, passes through the top table 12 and is connected with the gantry 21.

[0038] The top of the base 11 is provided with a free-falling landing platform 2. The upper part of the landing platform 2 is provided with a vertical column and a top platform 12. The top platform 12 is equipped with a roller 121 to ensure the stability of the movement of the landing platform 2 and avoid irregular swinging or interference during the falling process.

[0039] The sliding platform 3 is horizontally arranged on the top of the landing platform 2 and can move relative to the landing platform 2 in the horizontal direction. The bottom of the sliding platform 3 is provided with a transverse impact generator, and the upper part of the sliding platform 3 is provided with an inclined platform 4. The inclined platform 4 is connected to the sliding platform 3 through a hinge and can rotate around at least one horizontal axis to adjust the inclination angle of the battery pack 7. This design allows the simulation of the falling of the battery pack 7 at various inclination angles to meet the needs of different battery pack 7 structures and external environments.

[0040] The battery pack 7 is fixed on the top of the inclined platform 4, and by adjusting the angle of the inclined platform 4, the simulation of different inclination angles can be realized. The fixing method of the battery pack 7 ensures its stability during the test and can accurately reflect the falling process in actual application.

[0041] The transverse impact generator is composed of an impact execution member 51 and an impact trigger member 52. The impact execution member 51 is installed at the bottom of the sliding platform 3, extends downward and penetrates the landing platform 2, while the impact trigger member 52 is installed on the base 11 at the bottom of the landing platform 2. When the landing platform 2 freely falls to the preset position, the impact execution member 51 collides with the impact trigger member 52, causing the sliding platform 3 to produce a transient impact relative to the landing platform 2 in the horizontal direction. This design effectively simulates the horizontal impact force that the battery pack 7 may encounter when it freely falls.

[0042] The steel wire rope on the winch 13 is connected across the roller 121, passes through the top platform 12 and is connected with the gantry 21, thereby accurately controlling the falling height and speed of the landing platform 2. This system not only improves the adjustability of the landing platform 2, but also ensures the safety and stability during the test.

[0043] As shown in Figure 3 , Figure 4 and Figure 5 , the impact execution member 51 includes an execution column 511 which is fixedly arranged on the bottom of the sliding platform 3 in the longitudinal direction and penetrates the landing platform 2; the impact trigger member 52 includes a trigger seat 521 which is arranged on the base 11 at the termination position of the free-falling trajectory of the landing platform 2, and the top end of the trigger seat 521 is provided with an inclined impact surface 5211; when the execution column 511 falls with the landing platform 2 to contact the inclined impact surface 5211, the inclined impact surface 5211 converts the vertical movement of the execution column 511 into the horizontal impact movement of the sliding platform 3.

[0044] The execution column 511 is fixedly arranged on the bottom of the sliding platform 3 in the longitudinal direction and penetrates the entire structure of the falling platform 2. The execution column 511 can stably contact the trigger during the falling process, thereby effectively transmitting the impact force. Through this design, the synergy between the sliding platform 3 and the falling platform 2 can generate a controllable horizontal impact force.

[0045] The trigger seat 521 is arranged on the base 11 and located at the termination position of the free-fall trajectory of the falling platform 2. In order to ensure that the trigger can accurately respond to the movement of the falling platform 2, the top end of the trigger seat 521 is provided with an inclined impact surface 5211. This inclined impact surface 5211 takes into account the relative position of the falling platform 2 and the sliding platform 3 in design, which can ensure that the change of the movement direction of the execution column 511 occurs smoothly and accurately when it contacts the impact surface.

[0046] When the falling platform 2 is in free-fall, the execution column 511 will move downward with the falling of the falling platform 2 and eventually contact the inclined impact surface 5211. When the execution column 511 contacts the inclined impact surface 5211, the impact surface will effectively convert the vertical movement of the execution column 511 into the horizontal impact movement of the sliding platform 3 through its angle design. This conversion process ensures the generation of horizontal impact force through precise angle adjustment and mechanical transmission.

[0047] Through the design of the inclined impact surface 5211, the impact execution member 51 can accurately convert the vertical impact force into a horizontal impact force. Traditional impact execution members 51 can usually only produce impact in the vertical direction, but this design breaks through this limitation, enabling the device to simulate the horizontal impact force that the battery pack 7 may encounter in the actual environment in multiple dimensions, thereby more comprehensively evaluating the impact resistance performance of the battery.

[0048] As shown in Figure 4 The trigger seat 521 is rotatably arranged on the base 11 around the axis direction of the execution column 511, and the trigger seat 521 is further provided with a positioning bolt 522 capable of being fixedly connected with the base 11. The base 11 is provided with a threaded hole 111 distributed circumferentially along the rotation axis of the trigger seat 521, and the positioning bolt 522 is capable of being threadedly connected with the threaded hole 111.

[0049] In order to further enhance the flexibility and diversity of the test device, an adjustable trigger seat 521 is designed, so that the inclined impact surface 5211 of the trigger seat 521 can be directed in any direction, thereby generating a horizontal impact force in different directions.

[0050] The trigger seat 521 is arranged on the base 11 and can rotate around the axis direction of the execution column 511. The rotation capability of the trigger seat 521 enables the inclined impact surface 5211 to flexibly adjust its orientation, thereby realizing multi-angle generation of horizontal direction impact force. By rotating the trigger seat 521, the test personnel can accurately control the sliding table 3 to exert impact force in different directions to meet the diversified impact scenarios that different types of battery packs 7 may encounter in actual use.

[0051] In order to ensure that the trigger seat 521 maintains a stable and accurate position during adjustment, a positioning bolt 522 is arranged on the trigger seat 521. The positioning bolt 522 can be threadedly connected with the threaded hole 111 on the base 11, thereby locking the trigger seat 521 at the required rotation angle. The design of the positioning bolt 522 enables the trigger seat 521 to be firmly fixed on the base 11, avoiding unnecessary movement or deviation during impact testing.

[0052] A plurality of threaded holes 111 are arranged on the base 11 in a circumferential direction along the rotation axis of the trigger seat 521, and the threaded holes 111 are designed to provide multiple adjustment positions for the positioning bolt 522. By adjusting the combination of the positioning bolt 522 and the threaded hole 111, the trigger seat 521 can be accurately positioned at the required angle.

[0053] As shown in Figure 5 The bottom end of the execution column 511 is also provided with a rolling ball 512 rotatably connected thereto, and the execution column 511 is in rolling fit with the inclined impact surface 5211 through the rolling ball 512.

[0054] The bottom end of the execution column 511 is equipped with a rolling ball 512 structure rotatably connected thereto. This rolling ball 512 can freely rotate and forms a rolling contact mode with the inclined impact surface 5211, rather than a sliding contact. This design greatly reduces the resistance between the contact surfaces by converting friction into rolling friction. The friction coefficient of rolling friction is significantly reduced compared to sliding friction, so that the execution column 511 can move more smoothly during cooperation with the trigger seat 521.

[0055] As shown in Figure 5 The falling table 2 is provided with a guide opening 22 larger in diameter than the impact execution member 51, and the guide opening 22 is provided with a sliding groove 221 extending in the horizontal direction. The impact execution member 51 is provided with a positioning ring 513, and the outer contour of the positioning ring 513 extends into the sliding groove 221 and has a diameter smaller than that of the sliding groove 221.

[0056] On the falling platform 2, a guide opening 22 with a diameter larger than that of the impact execution member 51 is arranged, which is designed to provide sufficient horizontal displacement gap for the impact execution member 51, so as to ensure that the impact positioning ring 513 can freely and smoothly displace horizontally when entering the sliding groove 221, without being constrained to be stuck or deviated.

[0057] The impact execution member 51 is provided with a positioning ring 513, the outer contour of which extends into the sliding groove 221 and cooperates with the sliding groove 221. The positioning ring 513 is designed to ensure the accurate positioning and stability of the impact execution member 51 during sliding. Through the close cooperation with the sliding groove 221, the positioning ring 513 effectively prevents the deviation and shaking of the impact execution member 51 during sliding, and ensures that it always moves along the predetermined trajectory.

[0058] The contact surface between the positioning ring 513 and the sliding groove 221 is provided with a ball 5131 to reduce the friction between the positioning ring 513 and the sliding groove 221.

[0059] Referring to Figure 11 As another embodiment of the present application, the bottom end of the impact execution member 51 can be provided with an inclined surface structure. The inclined surface and the inclined impact surface 5211 of the trigger seat 521 form a complementary cooperation, and when they contact, a stable surface contact state is achieved. During the continuous movement of the impact execution member 51 in the vertical direction, the vertical displacement component can be converted into a horizontal thrust through the interaction of the inclined surfaces, thereby providing a horizontal impact for the impact execution member 51. Figure 6 and Figure 7 As shown in

[0060] When the sliding platform 3 is displaced relative to the falling platform 2 in the horizontal direction, the elastic restoring mechanism 6 needs to be overcome. The elastic restoring mechanism 6 is provided between the sliding platform 3 and the falling platform 2. When the sliding platform 3 is displaced in the horizontal direction during the impact test, the elastic resistance provided by the mechanism needs to be overcome to complete the impact action. After the impact is completed and the falling platform 2 is reset, the sliding platform 3 is automatically reset to the initial position under the action of the elastic restoring mechanism 6, ready for the next test. Figure 6 、 Figure 7 and Figure 8As shown, the falling platform 2 is provided with mounting ports 23 distributed around the sliding platform 3, and the elastic return mechanism 6 is arranged around the sliding platform 3. The elastic return mechanism 6 includes guide columns 61, clamping blocks 62, and elastic elements 63. The guide columns 61 are arranged in the longitudinal direction on the sliding platform 3. The clamping blocks 62 are arranged in close proximity to each other in the mounting ports 23. The top ends of the opposite sides of the two clamping blocks 62 are provided with inclined grooves 631 that combine to form a V-shaped groove, and the circumferential surface of the guide column 61 is in sliding cooperation with the two inclined grooves 631. The elastic elements 63 are arranged between the clamping blocks 62 and the mounting ports 23, and the two clamping blocks 62 elastically clamp the guide column 61.

[0061] When the sliding platform 3 moves relative to the falling platform 2, it will displace in the horizontal direction. At this time, the elastic return mechanism 6 plays a role and provides elastic force to resist the displacement of the sliding platform 3. Regardless of the direction in which the sliding platform 3 moves, the elastic return mechanism 6 always generates an opposite elastic force, ensuring that the sliding platform 3 can eventually return to the initial position.

[0062] The inertial force sensor can record the acceleration changes of the battery pack during the impact process in real time. By analyzing these acceleration data, the influence of the reaction force generated by the elastic return mechanism on the overall impact force can be identified, so that dynamic correction can be performed to obtain the true impact force acting situation.

[0063] The elastic return mechanism 6 includes elastic elements 63 such as springs, guide columns 61, and clamping blocks 62. When the sliding platform 3 displaces, the elastic elements 63 are compressed or stretched, storing potential elastic energy.

[0064] Through the cooperation of the guide columns 61 and the clamping blocks 62, the elastic elements 63 generate stable and adjustable reaction force during the resetting process, controlling the process of resetting the sliding platform 3. The guide columns 61 extend in the longitudinal direction and cooperate with the inclined grooves 631 of the clamping blocks 62 to guide the movement of the sliding platform 3, ensuring the accurate execution of the resetting action.

[0065] As shown in Figure 9 and Figure 10 The mounting ports 23 are provided with positioning rods 231 extending in the direction of close proximity of the two clamping blocks 62, and the clamping blocks 62 are provided with positioning holes in sliding cooperation with the positioning rods 231. The elastic elements 63 are arranged on the positioning rods 231.

[0066] In the mounting ports 23 of the sliding platform 3, positioning rods 231 extending in the direction of close proximity of the two clamping blocks 62 are arranged. The function of this positioning rod 231 is to ensure the relative position stability of the clamping blocks 62 during the resetting process. The combination of the positioning rod 231 and the clamping blocks 62 provides precise guidance, ensuring that the clamping blocks 62 slide along the correct path, thereby making the entire resetting process more stable and without deviation.

[0067] The clamping block 62 is provided with a positioning hole that cooperates with the positioning rod 231, and the positioning hole is in sliding cooperation with the positioning rod 231. During the resetting process, when the sliding table 3 is displaced, the clamping block 62 will slide along the positioning rod 231 accordingly, ensuring that the clamping block 62 always moves in the correct direction during the sliding process, thereby effectively guiding the sliding table 3 to reset to the original position.

[0068] As shown in Figure 9 and Figure 10 , the tilting table 4 includes a transverse adjustment table 41 and a longitudinal adjustment table 42; the bottom center of the transverse adjustment table 41 is provided with a transverse shaft 411, which is rotatably arranged on the top of the sliding table 3; the bottom center of the longitudinal adjustment table 42 is provided with a longitudinal shaft 421, which is rotatably arranged on the top of the transverse adjustment table 41, and the battery pack 7 is arranged at the top end of the longitudinal adjustment table 42.

[0069] The bottom center of the transverse adjustment table 41 is provided with a transverse shaft 411, which is rotatably arranged on the top of the sliding table 3. The function of the transverse adjustment table 41 is to allow the tilting table 4 to be adjusted in the horizontal direction, changing the transverse angle of the battery pack 7.

[0070] When the transverse adjustment table 41 is rotated by the transverse shaft 411, the sliding table 3 can be rotated and adjusted in the horizontal direction, thereby changing the inclination angle of the battery pack 7. This design supports the rotation of the shaft, making the adjustment process smooth and accurate.

[0071] The bottom center of the longitudinal adjustment table 42 is provided with a longitudinal shaft 421, which is rotatably arranged on the top of the transverse adjustment table 41. This design allows the longitudinal adjustment table 42 to vertically adjust the longitudinal angle of the sliding table 3, thereby adjusting the inclination angle of the battery pack 7 and moving the components of the device up and down.

[0072] The rotation of the longitudinal adjustment table 42 allows the system to achieve fine adjustment in the vertical direction, improving the adjustment range and flexibility of the device. By controlling the rotation of the longitudinal shaft 421, the longitudinal adjustment table 42 can adjust the height of the battery pack 7 to meet different angle requirements.

[0073] The battery pack 7 is arranged at the top end of the longitudinal adjustment table 42, so the battery pack 7 will move up and down with the rotation of the longitudinal adjustment table 42. This allows the battery pack 7 to flexibly adjust the angle according to the needs, whether it is to adapt to different working environments or to carry out more effective testing.

[0074] Through the joint adjustment of the transverse and longitudinal adjustment tables, the angle of the battery pack 7 can be adjusted in both directions at the same time, achieving more accurate and multi-angle adjustment.

[0075] AsFigure 9 and Figure 10 As shown, the two sides of the lateral adjustment platform 41 in the tilting direction are provided with lower abutting columns 43 threadedly connected thereto, the bottom ends of the lower abutting columns 43 abutting against the top end of the sliding platform 3; the two sides of the lateral adjustment platform 41 along the longitudinal adjustment platform 42 in the tilting direction are provided with upper abutting columns 44 threadedly connected thereto, the top ends of the upper abutting columns 44 abutting against the side of the longitudinal adjustment platform 42.

[0076] The lower abutting columns 43 are located on both sides of the lateral adjustment platform 41 and are threadedly connected thereto. The bottom ends of these lower abutting columns 43 are in contact with the top end of the sliding platform 3, forming a stable contact surface.

[0077] When the lower abutting columns 43 are rotated, due to their threaded connection characteristics, the vertical position of the columns will change, causing a height difference on both sides of the lateral adjustment platform 41. This change causes a height difference in the tilting direction of the lateral adjustment platform 41, thereby adjusting its lateral angle.

[0078] By precisely adjusting the height difference of the lower abutting columns 43, the precise tilting of the lateral adjustment platform 41 can be achieved, adapting to different angle requirements.

[0079] The upper abutting columns 44 are located on both sides of the longitudinal adjustment platform 42 and are connected to the lateral adjustment platform 41 through threaded connection. The top ends of the upper abutting columns 44 are in contact with the side of the longitudinal adjustment platform 42, forming a support point.

[0080] When the upper abutting columns 44 are rotated, due to their connection with the lateral adjustment platform 41, the adjustment will cause a height difference on both sides of the longitudinal adjustment platform 42. This height difference will cause the longitudinal adjustment platform 42 to tilt in the longitudinal direction.

[0081] Adjusting the height difference of the upper abutting columns 44 allows the tilting angle of the longitudinal adjustment platform 42 to be precisely adjusted, thereby affecting the overall vertical angle of the battery pack 7.

[0082] The adjustment of the lateral adjustment platform 41 and the longitudinal adjustment platform 42 is independent, but they are coordinated through the cooperation of the lower abutting columns 43 and the upper abutting columns 44. By adjusting the lateral angle of the lateral adjustment platform 41 and the longitudinal angle of the longitudinal adjustment platform 42 respectively, the attitude of the battery pack 7 can be precisely controlled.

[0083] When the lower abutting columns 43 adjust the lateral angle, the height change on both sides of the lateral adjustment platform 41 will affect the lateral balance of the battery pack 7; when the upper abutting columns 44 adjust the longitudinal angle, the tilting of the longitudinal adjustment platform 42 also affects the longitudinal balance of the system.

[0084] This hierarchical adjustment design ensures that the system can achieve precise adjustment in multiple directions, meeting the needs of various angle changes.

[0085] The above embodiments only express one or several embodiments of the present application, the description is more specific and detailed, but it cannot be understood as the limitation of the protection scope of the present application. It should be pointed out that for ordinary skilled in the art, without departing from the concept of the present application, a number of modifications and improvements can be made, which belong to the protection scope of the present application. Therefore, the protection scope of the present application should be subject to the appended claims.
