[0035] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0036] See also Figures 1 to 6 As shown, Figure 1 This is an overall structural diagram of the vibration device 10 provided in an embodiment of the present utility model. Figure 2 This is a schematic diagram of a usage scenario of the vibration device 10 provided in an embodiment of the present utility model. Figure 2 The figure shows the state where the vibration device 10 is clamping the battery module 20 to be tested. Figure 3 It is along Figure 2 Schematic diagram of the cross section along line AA. Figure 4 yes Figure 3 A partial enlarged view of area B in the middle. Figure 3 and Figure 4 The matching relationship between the card block 121 and the battery module 20 to be tested is shown together. Figure 5 It is along Figure 2 Schematic diagram of the cross section of the CC line, Figure 6 yes Figure 5 A partial enlarged view of the D area in the middle. Figure 5 and Figure 6 The assembly relationship between the connecting member 122, the clamping block 121 and the support 11 is jointly shown.

[0037] The embodiment of the present utility model provides a vibration device 10, which includes a support 11 and at least two groups of adjustment components 12. The support 11 is provided with a sliding groove 1111, and a clearance space 114 is formed on one side of the support 11. The support 11 is used to connect with the vibration equipment; the adjustment component 12 includes a clamping block 121 and a connecting member 122. The clamping block 121 is provided with a penetrating connecting hole 1211. The connecting member 122 is provided with the connecting hole 1211 and the sliding groove 1111 to connect the clamping block 121 and the support 11. One end of the connecting member 122 close to the support 11 is located in the clearance space 114, and the clamping block 121 is used to limit the battery.

[0038] Specifically, the two sides of the support 11 as shown in the figure are defined as the upper and lower parts of the support 11, the block 121 is stacked on the upper part of the support 11, and the clearance space 114 is formed below the support 11. The sliding grooves 1111 corresponding to the two connectors 122 can be parallel to each other, or can be configured according to the end face shape of the battery module 20 to be tested, so that the two blocks 121 can be close to each other to stably clamp the battery module 20 to be tested. The figure is only a schematic diagram of one embodiment. The connector 122 can be adjusted as needed to change the force between the connector 122, the block 121 and the support 11. When the connector 122 is in a locked state, the block 121 can slide relative to the support 11; when the connector 122 is in an adjusted state, the position of the block 121 and the support 11 is relatively fixed. The connector 122 can be the bolt and nut 1222 shown in the figure, or it can be a detachable connecting part commonly used in the field, such as a pin or a clamp.

[0039] In order to enable those skilled in the art to have a further understanding of this solution, the assembly process of the vibration device 10 and the battery module 20 to be tested will be explained in detail below, but it is worth noting that this does not impose any limitation on the technical solution of the present utility model. In this embodiment, when it is necessary to change the size of the clamped battery module 20, at least one of the connectors 122 is adjusted to the adjustment state, the sliding block 121 increases the distance between the two block 121 brackets, the battery module 20 to be measured is placed above the bracket and between the two blocks 121, the sliding block 121 makes the battery module 20 to be measured abut against the two blocks 121 at the same time, and then the connector 122 is adjusted to the locked state, the block 121 is relatively fixed to the bracket, the battery module 20 to be measured is clamped by the block 121, and the assembly is completed.

[0040] It should be noted that the vibration device 10 provided in this embodiment does not limit its method of fixing the battery module 20. The figure shows that two opposing clamping blocks 121 directly clamp the battery module 20 to be tested. In other embodiments, the battery module 20 can also be detachably connected to the clamping blocks 121. For example, some battery modules 20 are provided with fixed end plates or fixed ears at both ends. The clamping blocks 121 can be adjusted to a preset position, and then the workpiece can be fixed by using bolts or other fixing means to penetrate the fixed end plates or fixed ears, so that the battery module 20 is connected to the clamping blocks 121. In the above embodiment, corresponding fixing holes should be provided on the clamping blocks 121.

[0041] The advantage of this design is that, in the existing vibration device 10, the end of the connecting member 122 close to the support 11 will protrude from the surface of the support 11, which means that when the support 11 is placed on a flat table, the connecting member 122 will lift up the vibration device 10, making it impossible for the support 11 to be stably connected to the table. Although the parts of the existing vibration measurement equipment used to place the vibration device 10 are mostly hollow frames, the above defects do not affect the placement of the vibration device 10, but such a structure still limits the application scenarios of the vibration device 10. A clearance space 114 is formed under the support 11 of the vibration device 10 provided in this embodiment, and the end of the connecting member 122 close to the support 11 is hidden in the clearance space 114. When the support 11 is placed on a flat table, the connecting member 122 does not come into contact with the flat table, and the connecting member 122 and the block 121 can still be freely adjusted relative to the support 11, which expands the application scenarios of the vibration device 10.

[0042] Optionally, the support 11 includes a first bottom plate 111, a second bottom plate 112 and a third bottom plate 113, the second bottom plate 112 is arranged at both ends of the first bottom plate 111, the second bottom plate 112 and the first bottom plate 111 are surrounded to form a clearance space 114, the first bottom plate 111 is provided with a sliding groove 1111, and the third bottom plate 113 is used to connect with the vibration equipment.

[0043] A specific implementation is that the third base plate 113 is parallel to the first base plate 111, and the lower surfaces of the two third base plates 113 shown in the figure are flush, and a plurality of penetrating fixing holes are arranged at intervals on the third base plate 113, and the fixing holes are used to fix to the vibration equipment. Obviously, without setting the fixing holes, the third base plate 113 can also be welded to the vibration device 10 or fixed using a clamp.

[0044] This embodiment provides a specific structure of a support 11, wherein the first base plate 111 is used to support the adjustment component 12, the third base plate 113 is used to be fixed to the vibration device, and the second base plate 112 connects the first base plate 111 and the third base plate 113 while forming a clearance space 114 with the first base plate 111. The above structure is simple to process, and mass production can be achieved by welding sheets, extrusion molding or stamping.

[0045] See also Figure 7 , Figure 7 It is a structural schematic diagram of the vibration device provided by an embodiment of the utility model from another perspective.

[0046] Furthermore, the support 11 also includes a reinforcing rib 115, and the reinforcing rib 115 includes a first reinforcing rib 1151 and a second reinforcing rib 1152 arranged in the clearance space 114. The first reinforcing rib 1151 spans the first bottom plate 111 and is connected to the second bottom plate 112. The second reinforcing rib 1152 is arranged on the first bottom plate 111 and is connected to the first reinforcing rib 1151.

[0047] The provision of the reinforcing ribs 115 enhances the structural strength of the support 11. Specifically, the first reinforcing ribs 1151 fix the relative positional relationship between the first base plate 111 and the second base plate 112, reducing the risk of collapse of the support 11 during vibration. The second reinforcing ribs 1152 reinforce both ends of the first base plate 111 to prevent curling of the first base plate 111 under long-term cyclic stress.

[0048] Optionally, a side of the block 121 away from the clearance space 114 is provided with an avoidance groove 1212 , the avoidance groove 1212 surrounds the connecting hole 1211 , and one end of the connecting member 122 is accommodated in the avoidance groove 1212 .

[0049] See also Figure 4 , Figure 4 A configuration of the avoidance groove 1212 is shown. Because the end of the connector 122 closest to the block 121 is accommodated in the avoidance groove 1212, and the upper surface of the block 121 has no protruding structure, when clamping a special-shaped battery module 20 with a protrusion above, for example, when the battery module 20 is provided with end caps at both ends and the end caps are located in the upper half of the end surfaces of the battery module 20, the block 121 of this embodiment can avoid the connector 122 from interfering with the battery module 20, resulting in unstable fixation. In addition, some battery modules 20 directly connected to the block 121 usually abut against the upper surface of the block 121. The block 121 of this embodiment is also more suitable for such application scenarios.

[0050] See also Figure 8 As shown, Figure 8 It is a schematic diagram of the cooperation between the sleeve 123 and the connecting piece 122.

[0051] Optionally, the connecting member 122 includes a screw 1221 and a nut 1222, the screw 1221 passes through the connecting hole 1211 and the sliding groove 1111, and the nut 1222 and the screw 1221 are connected and accommodated in the clearance space 114; the adjustment component 12 also includes a sleeve 123 sleeved on the outer periphery of the screw 1221, and the sleeve 123 is assembled in the connecting hole 1211 and the sliding groove 1111.

[0052] On the one hand, the sleeve 123 can play a limiting role. When the screw 1221 and the nut 1222 are against the two ends of the sleeve 123, the resistance to further tightening is greatly increased. Moreover, because the sleeve 123 is small in size and regular in shape, the sleeve 123 can be selected with a material that is much stronger than the support 11 and the block 121. The setting of the sleeve 123 avoids structural damage caused by over-tightening of the screw 1221; on the other hand, the sleeve 123 separates the screw 1221 from the support 11, avoiding wear caused by relative sliding between the threaded section of the screw 1221 and the side wall of the sliding groove 1111, thereby extending the service life of the screw 1221.

[0053] See also Figure 9 As shown, Figure 9 It is a schematic diagram of the cooperation between the spring 124 and the connecting member 122.

[0054] In another embodiment of the present invention, the connecting member 122 includes a screw 1221 and a nut 1222. The screw 1221 passes through the connecting hole 1211 and the sliding groove 1111. The nut 1222 and the screw 1221 are connected and accommodated in the clearance space 114. The adjustment assembly 12 also includes a spring 124 sleeved on the outside of the connecting member 122. The spring 124 is assembled in the connecting hole 1211 and the sliding groove 1111, and the spring 124 elastically supports the nut 1222. Specifically, the length of the spring 124 in its natural state is greater than the sum of the thickness of the support 11 and the thickness of the block 121. The length of the spring 124 in its compressed state is less than the sum of the thickness of the support 11 and the thickness of the block 121.

[0055] When the connector 122 is adjusted to the locked state, the spring 124 pushes the nut 1222 away from the screw 1221, increasing the force between the threads of the nut 1222 and the screw 1221, preventing the connector 122 from accidentally loosening when the battery module 20 is subjected to a vibration test.

[0056] See also Figure 10 As shown, Figure 10 This is a schematic diagram of the cooperation between the card block 121 and the battery in one embodiment of the present invention.

[0057] In another embodiment of the present invention, the clamping block 121 is provided with a plurality of step-like structures, and the step-like structures on one clamping block 121 face the step-like structures on another clamping block 121 , and the step-like structures are used to limit the battery.

[0058] In this embodiment, without adjusting the connector 122 and changing the positional relationship between the clamping block 121 and the support 11, a variety of spacing relationships exist between the two clamping blocks 121, allowing for adaptability to various assembly requirements. Compared to implementations that adapt the size of the battery module 20 to be measured by simply moving the clamping block 121, this embodiment requires less frequent adjustment of the clamping block 121. This allows for more stable fixation of the connector 122 each time without compromising operational efficiency, reducing the likelihood of connector 122 failure due to vibration during testing.

[0059] It should be noted that in order to better play the effect of the step-like structure, the block 121 can be adjusted according to the general experience in this field. For example, in the technical solution of two blocks 121 clamping the battery module 20, elastic pads are provided on the step surfaces opposite to each other of the two blocks 121, or elastic washers are provided between the block 121 and the connector 122, so that the battery module 20 can be more easily inserted between the blocks 121; or, fixing holes are provided above each step, so that the battery module 20 can be fixed to the block 121 using bolts or the like after being placed above the step. Of course, even if the block 121 is not improved, the battery module 20 can be clamped between the two blocks 121 if the gap between the blocks 121 is properly adjusted, and this does not limit the scope of protection of the present utility model.

[0060] See also Figure 11 As shown, Figure 11 It is a structural diagram of a vibration device 10 provided in another embodiment of the present invention.

[0061] In one embodiment of the present invention, the support 11 is further provided with a plurality of first locking holes 1112, and the plurality of first locking holes 1112 are arranged at intervals in the extension direction of the sliding groove 1111; the adjustment assembly 12 also includes a locking piece 125, and a penetrating second locking hole 1213 is provided on the block 121, and the locking piece 125 passes through the second locking hole 1213 and is inserted into one of the first locking holes 1112.

[0062] Considering that the vibration test will apply high-frequency dynamic stress to the overall structure, this places a high demand on the friction fixation between the block 121 and the support 11. Continuing to increase the pressure of the locking member 125 on the block 121 and the support 11 will increase the difficulty of assembly and may lead to the risk of structural damage. In this embodiment, when it is necessary to fix the relative position of the block 121 and the support 11, in addition to the locking effect of the connecting member 122, the locking member 125 is passed through the first locking hole 1112 on the support 11 and the second locking hole 1213 on the block 121. When the block 121 tends to slip relative to the support 11, the locking member 125 abuts against the hole wall of the first locking hole 1112 and the hole wall of the second locking hole 1213. Before the locking member 125 is damaged, the block 121 and the support 11 are always relatively stationary.

[0063] Furthermore, to facilitate assembly of the locking member 125, the first locking holes 1112 on the support 11 should be arranged in a one-to-one correspondence with the dimensions of the multiple battery modules 20 to be tested, so that when the locking member 125 passes through the first locking hole 1112 and the second locking hole 1213, the battery module 20 is securely secured. Alternatively, the first locking hole 1112 can be replaced with a first locking groove, with the first locking groove extending parallel to the sliding direction of the clamping block 121. In this embodiment, the locking effect of the locking member 125 is weakened, and assembly of the locking member 125 is accordingly easier. When the clamping block 121 loses its securement and slides outward, the sliding distance of the clamping block 121 is limited by the length of the first locking groove. Considering that the movement of the clamping block 121 is generally accompanied by the expansion of the battery module 20, in practice, when the locking member 125 slides along the first locking groove until the clamping block 121 is re-locked, there is still a certain probability that the expanded battery module 20 will be secured between the clamping block 121. In this case, the locking member 125 still performs the function of a safety lock.

[0064] See also Figure 12 As shown, Figure 12 It is a top view of a vibration device provided by another embodiment of the present utility model.

[0065] Optionally, the sliding groove 1111 includes a first sliding groove 11111 and a second sliding groove 11112 , and the extending directions of the first sliding groove 11111 and the second sliding groove 11112 are perpendicular.

[0066] Specifically, the vibration device 10 includes four sets of adjustment assemblies 12, two of which are slidably connected to the first sliding slot 11111, and the remaining two are slidably connected to the second sliding slot 11112. The two sets of adjustment assemblies 12 engaged with the first sliding slot 11111 clamp the battery module 20 along its length, while the two sets of adjustment assemblies 12 engaged with the second sliding slot 11112 clamp the battery module 20 along its width. In this way, the battery module 20 is restrained in more dimensions, making the assembly of the battery module 20 more stable.

[0067] To achieve the above-mentioned purpose, the present invention provides a solution: a testing device, which includes a vibration device and any one of the above-mentioned vibration devices 10, wherein the vibration device 10 is connected to the vibration device.

[0068] During use of the test equipment provided in this embodiment, the vibration device can always remain fixed to the vibration device 10. When testing battery modules 20 of different sizes, only the adjustment component 12 needs to be adjusted to adapt, without having to disassemble and replace the vibration device 10. On the one hand, the test equipment no longer needs to be equipped with a series of different types of vibration devices 10, reducing the idle rate of the equipment. On the other hand, because the vibration device 10 does not need to be frequently disassembled, a more stable connection method can be adopted between the vibration device 10 and the vibration equipment, thereby improving the accuracy of the test data.

[0069] The advantage of this design is that the connecting piece 122 of the vibration device 10 is accommodated in the clearance space 114, and even if the mating surface of the vibration equipment is a flat table surface, it does not hinder the installation of the vibration device 10. Therefore, in the selection of vibration equipment, this solution has more flexible matching space.

[0070] It should be noted that all directional indications in the embodiments of the present invention (such as up, down, left, right, front, back, etc.) are only used to explain the relative position relationship and movement status of the various components in a certain specific posture. If the specific posture changes, the directional indication will also change accordingly.

[0071] It should also be noted that when an element is referred to as being "fixed to" or "disposed on" another element, it may be directly on the other element or there may be an intervening element. When an element is referred to as being "connected to" another element, it may be directly connected to the other element or indirectly connected to the other element through an intervening element.

[0072] In addition, the descriptions of "first," "second," etc. in this utility model are for descriptive purposes only and should not be understood as indicating or implying their relative importance or implicitly indicating the number of the technical features indicated. Therefore, the features defined as "first" or "second" may explicitly or implicitly include at least one of such features. In addition, the technical solutions between the various embodiments can be combined with each other, but this must be based on the fact that they can be implemented by ordinary technicians in this field. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by this utility model.
