[0034] The following reference Figures 1 to 6 This application describes a vibration testing apparatus according to some embodiments.

[0035] See Figures 1 to 6 As shown, an embodiment of this application provides a vibration testing device, including: a vibration testing table 1, a pressing component 2, a first fastening component 3, and a positioning component 4; wherein, the vibration testing table 1 is used to place the object to be tested. It should be noted that the object to be tested can be a battery pack 7, and this will be used as an example in the following description. Of course, this vibration testing device is not limited to the vibration testing of battery pack 7, but can also be used in the vibration testing of other products. That is to say, the object to be tested can also be other products, etc., depending on the actual needs.

[0036] The pressing member 2 is used to press onto the object to be tested, such as the battery pack 7, and the first fastening member 3 is used to fix the pressing member 2 to the vibration test table 1 so that the object to be tested, such as the battery pack 7, is positioned in the first preset direction a.

[0038] As can be seen from the structure described above, this application provides a vibration testing device, the general process of which is as follows: First, the battery pack 7 to be tested is placed on the vibration testing table 1. Then, the positioning component 4 is used to position the object to be tested. Finally, the pressing component 2 is used to press the battery pack 7 and fix it to the vibration testing table 1. Finally, the vibration testing table 1 is started to begin the test. It should be noted that the above steps are only an example and can be adjusted according to actual needs.

[0039] As can be seen, this application designs a set of battery pack vibration testing fixtures to simulate the vibration environment that the battery pack may encounter during transportation or actual use, in order to verify the structural stability and performance reliability of the battery pack. Moreover, in this application, positioning component 4 is used to position the battery pack 7 in the horizontal direction, and pressing component 2 is used to position the battery pack 7 in the vertical direction, thereby constraining the battery pack 7 so that the battery pack 7 will not fly off the test stand during the vibration test, ensuring the normal conduct of the test and the accuracy of the test results.

[0040] Furthermore, preferably, the battery pack 7 has a cuboid structure, and a positioning member 4 is provided at each of the four corners of the battery pack 7, which further improves the positioning effect. Of course, it is not limited to this, and other structures can also be used, such as: providing positioning members 4 only at two opposite corners of the battery pack 7, or providing positioning members 4 on opposite sides of the battery pack 7, or providing positioning members 4 on all four sides of the battery pack 7.

[0041] Further, preferably, the first preset direction a is a vertical direction, such as the height direction of the battery pack 7; the second preset direction b is an X direction in the horizontal plane, such as the length direction of the battery pack 7; the second preset direction b is an X direction in the horizontal plane, such as the width direction of the battery pack 7.

[0042] In this embodiment, preferably, as follows: Figures 1 to 3 As shown, the positioning component 4 and the vibration test bench 1 are detachably connected via the second fastening component 5.

[0043] As can be seen from the structure described above, the positioning component 4 and the vibration test bench 1 are connected in a detachable manner, which facilitates installation.

[0044] Furthermore, preferably, the second fastening member 5 is a screw or bolt. Of course, it is not limited to this and can be designed according to actual needs.

[0045] It should be noted that the connection between the positioning component 4 and the vibration test bench 1 is not limited to this. The two can also use snap-fit ​​or other connection methods, depending on the actual needs.

[0046] In this embodiment, preferably, as follows: Figure 4 As shown, the vibration test bench 1 has a plurality of first mounting holes 11, and the plurality of first mounting holes 11 are arranged in a row along the second preset direction b and the third preset direction.

[0047] Further, preferably, such as Figures 1 to 3 As shown, the positioning member 4 has a second mounting hole 43, and the second fastening member 5 is installed in the second mounting hole 43 and one of the first mounting holes 11 in sequence to fix the positioning member 4 to the vibration test bench 1.

[0048] As can be seen from the structure described above, multiple first mounting holes 11 arranged in an array are provided on the vibration test bench 1, which facilitates the selection of appropriate positions for the aforementioned positioning components 4 according to actual needs, making assembly easier, and can accommodate the installation of multiple positioning components 4.

[0049] Furthermore, preferably, the aforementioned first mounting hole 11 can be a threaded round hole, and the aforementioned second mounting hole 43 can be a round hole with a smooth inner wall, or a threaded round hole, etc., depending on actual needs.

[0050] In this embodiment, preferably, as follows: Figures 1 to 3 , Figure 4 As shown, the positioning component 4 is L-shaped.

[0051] As can be seen from the structure described above, the first extension 41 of the L-shaped positioning member 4 extends along the second preset direction b, and the second extension 42 of the L-shaped positioning member 4 extends along the third preset direction. The second extension 42 and the third extension abut against the two perpendicularly arranged sides of the battery pack 7. The second extension 42 is used to limit the battery pack 7 in the third preset direction, and the third extension is used to limit the battery pack 7 in the second preset direction b. Based on this, the four positioning members 4 cooperate to achieve complete positioning of the battery pack 7 in the second preset direction b and the third preset direction, which can further enhance the realism of the simulation.

[0052] Furthermore, preferably, the number of second fastening members 5 can be multiple, and when the positioning member 4 is an L-shaped structure, the second fastening members 5 are provided on both sides and near the top corner to improve the fastening effect. Of course, it is not limited to this, and multiple positions of the second fastening members 5 can be set according to actual needs. In addition, the number of second fastening members 5 is not limited to multiple, and can also be one, etc.

[0053] It should be noted that the positioning component 4 is not limited to an L-shaped structure; it can also be other shapes, such as an X-shape, etc., depending on the actual needs.

[0054] In this embodiment, preferably, as follows: Figure 1 and Figure 5 As shown, the positioning member 4 is provided with a first positioning protrusion 44 along the second preset direction b and toward the object to be detected, such as the battery pack 7. That is, the first positioning protrusion 44 is provided on the first extension 41, and the first positioning protrusion 44 is used to abut against the side of the object to be detected, such as the battery pack 7.

[0055] The positioning member 4 has a second positioning protrusion 45 that is provided along a third preset direction and toward the object to be detected, such as the battery pack 7. That is, the second positioning protrusion 45 is provided on the second extension 42 and is used to abut against the side of the object to be detected, such as the battery pack 7.

[0056] As can be seen from the structure described above, a clearance cavity is formed between the first positioning protrusion 44, the second positioning protrusion 45, the first extension 41, and the second extension 42, which can avoid the structure at the top corner of the battery pack 7 and prevent interference. Moreover, by setting the positioning protrusion, it is easier to abut and cooperate with different positions on the battery pack 7, making it more adaptable.

[0057] Furthermore, preferably, the aforementioned first positioning protrusion 44, second positioning protrusion 45, first extension 41, and second extension 42 are an integral structure. However, this is not the only possibility; they can also be separate structures, assembled later by welding or bolts, depending on actual needs. It should be noted that the structure is not limited to simultaneously providing the first positioning protrusion 44 and the second positioning protrusion 45. Alternatively, depending on actual needs, only the first positioning protrusion 44 or only the second positioning protrusion 45 may be provided, or neither the first positioning protrusion 44 nor the second positioning protrusion 45 may be provided.

[0058] In this embodiment, preferably, as follows: Figure 3 and Figure 6As shown, the pressing member 2 extends along a third preset direction, and the pressing member 2 forms a plurality of first through holes 21 arranged sequentially at intervals along the third preset direction. The vibration test table 1 forms a plurality of second through holes arranged sequentially at intervals along a second preset direction b, and the first fastening member 3 is detachably installed in the first through holes 21 and the second through holes.

[0059] As can be seen from the structure described above, the pressing component 2 and the vibration test bench 1 are detachably connected by the first fastening component 3, which facilitates installation and disassembly, improves the convenience of operation, and the position of the pressing component 2 can be adjusted according to the actual height of the battery pack 7 to be tested to meet different usage requirements.

[0060] Furthermore, preferably, the first fastening member 3 is a combination structure of a screw and a nut. Of course, it is not limited to this and can be selected according to actual needs.

[0061] Furthermore, preferably, the second through hole and the aforementioned first mounting hole 11 are the same hole, so there is no need to open a second through hole separately, and only the existing first mounting hole 11 is used, which improves the efficiency of device processing and manufacturing.

[0062] In this embodiment, preferably, as follows: Figures 1 to 3 As shown, there are multiple pressing components 2, and the multiple pressing components 2 are arranged sequentially at intervals along the second preset direction b.

[0063] As can be seen from the structure described above, multiple pressing components 2 are sequentially pressed onto the top of the battery pack 7 along the second preset direction b, increasing the pressing area and making the battery pack 7 relatively stable. This can accurately simulate the actual transportation or use environment of the battery pack 7 and avoid test errors caused by insecure fixing.

[0064] It should be noted that the extension direction of the pressing member 2, the arrangement direction of the plurality of first through holes 21 thereon, and the arrangement direction of the plurality of pressing members 2 are not limited to the above. They can also be selected according to actual needs. For example, the pressing member 2 can extend along the second preset direction b, and the pressing member 2 can form a plurality of first through holes 21 arranged sequentially and spaced along the second preset direction b. On this basis, the plurality of pressing members 2 can be arranged sequentially and spaced along the third preset direction, etc.

[0065] In this embodiment, preferably, as follows: Figures 1 to 3 As shown, the pressure member 2 is a hollow beam structure, which meets the strength requirements without damaging the battery. Of course, it is not limited to this; other structures can also be used for the pressure member 2, such as a flat plate structure or a solid beam, etc.

[0066] In this embodiment, preferably, as follows: Figure 6As shown, a first protective member 6 is provided on the side of the pressing member 2 that is close to the object to be tested, such as the battery pack 7, to protect the object to be tested, such as the battery pack 7.

[0067] Furthermore, preferably, the first protective component 6 is foam.

[0068] In this embodiment, preferably, as follows: Figure 6 As shown, a second protective member is provided on the side of the positioning member 4 that is close to the object to be detected, such as the battery pack 7, to protect the object to be detected, such as the battery pack 7.

[0069] Furthermore, preferably, the second protective component is foam.

[0070] In summary, the vibration testing device provided in this application has the following structure and advantages:

[0071] This device uses a combination of positioning component 4 and pressing component 2 to ensure the stability of battery pack 7 during vibration, avoid test errors caused by insecure fixing, and is reusable to ensure the consistency of vibration simulation environment for different batches of battery pack 7, and can effectively reduce test costs.

[0072] It is evident that this vibration testing device, through a stable fixing method and combined with the simulated vibration of the vibration test bench 1, can effectively evaluate the performance of the battery pack 7 under vibration environment, providing an important basis for the design and improvement of the battery pack 7.

[0073] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them.
