[0033] Reference Figures 1 to 5 , is an embodiment of a battery vibration test clamping tooling of the utility model, comprising a plurality of fixing blocks 1, a clamping assembly and a base 2, wherein the fixing block 1 is provided with a placement groove 101 whose shape is adapted to the battery 16 to be tested, the clamping assembly can fix a plurality of batteries 16 to be tested in the plurality of placement grooves 101 at the same time, and the fixing block 1 is detachably arranged in the base 2.

[0034] The number of fixing blocks 1 can be determined according to the number of batteries 16 that actually need to be tested, and the manufacturer of the battery 16 determines the specific size of the fixing block 1 according to the model of the battery 16 produced by the manufacturer. By providing a placement groove 101 that matches the battery 16 to be tested in the fixing block 1, no matter what the shape of the battery 16 is, it can be surrounded by the placement groove 101, and by cooperating with the clamping assembly, the battery 16 can be well fixed; at the same time, the clamping assembly can fix several batteries 16 to be tested in several placement grooves 101 at the same time, so that multiple batteries 16 can be tested at the same time; when it is necessary to test batteries 16 of different sizes, it is only necessary to replace the fixing block 1 with a placement groove that matches the battery 16 to be tested in the base 2.

[0035] The base 2 can integrate the fixed block 1, so that by connecting the base 2 to the vibration source, the effect of vibrating all the fixed blocks 1 at the same time can be achieved, which is convenient and quick; on the other hand, when it is necessary to test batteries 16 of different models and sizes, it is only necessary to remove the fixed block 1 from the base 2 and install other fixed blocks 1 corresponding to the size of the battery 16 to be tested on the base 2.

[0036] In this embodiment, the base 2 is provided with a plurality of slots 3 adapted to the fixing block 1 , and the fixing block 1 is placed in the slots 3 ; the slots 3 and the fixing block 1 are provided with limit assemblies for preventing the fixing block 1 from rotating in the slots 3 .

[0037] Specifically, refer to Figure 1 , Figure 3 and Figure 5 The base 2 is in the shape of a rectangular parallelepiped, and the number of the slots 3 corresponds to the number of the fixed blocks 1. The specific number can be set according to the actual situation. In this embodiment, ten slots 3 are provided on the top of the base 2, that is, there are ten fixed blocks 1. The ten slots 3 are arranged in two rows, and there are five rows on the base 2. The shape of the fixed block 1 can be rectangular parallelepiped, prism-shaped or cylindrical. In this embodiment, the slot 3 is preferably cylindrical, and the slot 3 is adapted to the shape of the fixed block 1. The slot 3 is also cylindrical. The slot 3 is vertically opened at the top of the base 2, and the fixed block 1 can be inserted into the slot 3 from the top of the base 2. Since the slot 3 and the fixed block 1 are both cylindrical, the fixed block 1 is easy to rotate in the slot 3. In order to ensure that the fixed block 1 remains relatively fixed in the slot 3, a limit assembly is provided on the slot 3 and the fixed block 1.

[0038] In this embodiment, the limiting assembly includes a limiting block 4 and a limiting groove 5; the limiting block 4 is arranged on the fixed block 1, the limiting groove 5 is arranged in the card slot 3 along the extension direction of the card slot 3, and the limiting block 4 is adaptively arranged in the limiting groove 5.

[0039] Specifically, refer to Figure 2 , Figure 3 and Figure 5The shapes of the limiting groove 5 and the limiting block 4 can be prism-shaped, cylindrical-shaped, etc. In this embodiment, the shapes of the limiting groove 5 and the limiting block 4 are rectangular parallelepiped, the limiting groove 5 is opened on the inner side wall of the card slot 3 along the extension direction of the card slot 3, and the limiting groove 5 passes through the top wall of the base 2, the limiting block 4 is arranged on the fixed block 1 along the length direction of the fixed block 1, and the axial length of the limiting block 4 and the fixed block 1 is equal, the limiting block 4 can be fixed on the fixed block 1 by welding, riveting, bolt connection, etc., and the one-piece molding method is selected in this embodiment. When the fixed block 1 is inserted into the card slot 3, the limiting block 4 needs to be aligned with the limiting groove 5, and then the fixed block 1 is inserted into the card slot 3 from top to bottom, and the bottom of the fixed block 1 is abutted against the bottom of the card slot 3, at this time, the limiting block 4 will be in a state of being embedded in the limiting groove 5, and the limiting block 4 only has the freedom to move upward, so it can prevent the fixed block 1 from rotating in the card slot 3.

[0040] In this embodiment, the fixing block 1 is provided with a placement opening 102 connected to the placement groove 101, and the battery 16 to be tested passes through the placement opening 102 and enters the placement groove 101; the clamping assembly includes a pressing plate 6 and a first connecting rod 7, the pressing plate 6 is located above the placement opening 102, one end of the first connecting rod 7 is movably connected to the pressing plate 6, and the other end is connected to the base 2.

[0041] Specifically, the placement groove 101 is opened in the fixing block 1 along the axis of the fixing block 1, and the placement groove 101 passes through the top of the fixing block 1, thereby forming a placement opening 102. In this way, the placement opening 102 is also adapted to the shape of the battery to be tested 16, so that the gap between the placement opening 102 and the battery to be tested 16 can be reduced as much as possible. The number of the first connecting rods 7 is any number greater than one. In this embodiment, there are eight first connecting rods 7, and the eight first connecting rods 7 are symmetrically arranged on the base 2 in groups of four with the longitudinal midline of the base 2 as the symmetry axis, and the first connecting rods 7 are located outside the slot 3. The pressing plate 6 is located above the base 2, and the first connecting rod 7 passes through the pressing plate 6, so that the pressing plate 6 can move up and down along the first connecting rod 7. In order to achieve this effect, in this embodiment, the first connecting rod 7 is a screw rod, and the first connecting rod 7 passes through the base 2 from the bottom of the base 2 and is connected to the pressing plate 6. A nut is also provided on the first connecting rod 7, and the nut is located at the top of the pressing plate 6. When in use, the battery 16 to be tested is first placed in the placement groove 101, and then the pressing plate 6 is moved downward to abut against the top of the battery 16, and then the nut is screwed to tighten the pressing plate 6. At the top of the battery 16, the battery 16 to be tested is pressed tightly into the placement groove 101 of the fixing block 1. Since the placement groove 101 is adapted to the shape of the battery 16 to be tested, the surrounding side and the bottom of the battery 16 are all covered in the placement groove 101, that is, the placement groove 101 satisfies the fixation of the battery 16 in the X and Y directions, and the pressing plate 6 presses the battery 16 tightly, so that the battery 16 is tightly against the bottom of the placement groove 101, which satisfies the fixation of the battery 16 in the Z direction, so that the battery 16 to be tested is well fixed. When it is necessary to fix another batch of batteries 16 of different heights, the position of the pressing plate 6 on the first connecting rod 7 can be adjusted to ensure that the pressing plate 6 can be pressed on the top of the battery 16. If the height of the battery 16 is too large, the first connecting rod 7 can be replaced with a longer one to ensure that the pressing plate 6 can be pressed on the top of the battery 16.

[0042] In another embodiment, the first connecting rod 7 can also be a smooth rod, and the first connecting rod 7 is provided with a plurality of positioning holes 111 along its length direction, and the pressure plate 6 is penetrated with a spring pull-out pin at a position close to the first connecting rod 7. When the pressure plate 6 moves to an appropriate position, the spring pull-out pin will be inserted into the positioning hole 111 to realize the positioning of the pressure plate 6.

[0043] In this embodiment, the bottom of the fixing block 1 is further provided with a first opening 103 which is in communication with the placement groove 101. In order to prevent the battery 16 from passing through the first opening 103, the area of ​​the first opening 103 is smaller than the cross section of the battery 16. When the battery 16 is placed in the placement groove 101, since the placement groove 101 is adapted to the shape of the battery 16, there is very little air in the placement groove 101 at this time, so that the air pressure in the placement groove 101 is low and it is difficult to take out the battery 16. Therefore, by providing the first opening 103 at the bottom of the placement groove 101, even if there is a battery 16 in the placement groove 101, the air pressure in the placement groove 101 is balanced with the outside, so that it is easy to take out the battery 16. On the other hand, a plurality of second openings 201 corresponding to the card slots 3 are also provided at the bottom of the base 2. Since the shapes of the card slots 3 and the fixing block 1 are also adapted, the fixing block 1 is difficult to be taken out of the card slots 3 due to the above reasons. However, the existence of the second openings 201 balances the air pressure in the card slots 3 with the air pressure outside, so that the fixing block 1 can be taken out of the card slots 3 more conveniently. At the same time, in order to ensure that the first opening 103 can communicate with the outside world without being blocked by the base 2, the first opening 103 is communicated with the second opening 201.

[0044] In this embodiment, the clamping assembly also includes a stabilizing plate 8 and a second connecting rod 9, the stabilizing plate 8 is located below the pressing plate 6, and the stabilizing plate 8 is located above the placement opening 102; one end of the second connecting rod 9 is movably connected to the stabilizing plate 8, and the other end is connected to the base 2; a stabilizing opening 801 corresponding to the placement opening 102 is provided at the bottom of the stabilizing plate 8, and the stabilizing opening 801 is adapted to the shape of the battery 16 to be tested.

[0045] Specifically, there are five stabilizing plates 8, and both ends of each stabilizing plate 8 in the length direction are provided with stabilizing openings 801 adapted to the top of the battery 16, so that each stabilizing plate 8 can be mounted on the top of the same row of batteries 16. The stabilizing opening 801 runs through the stabilizing plate 8, and the stabilizing opening 801 is set in a step shape, so that the top of the battery 16 does not pass through the stabilizing opening 801, and the positive electrode of the battery 16 can pass through the stabilizing opening 801, thereby preventing the positive electrode protrusion of the battery 16 from being crushed. By setting the stabilizing opening 801, the stability of the battery 16 when it is fixed can be further increased, and the battery 16 can be prevented from shaking during the vibration test. The second connecting rod 9 is a hexagon socket bolt, and the second connecting rod 9 passes through the stabilizing plate 8 and is threadedly connected to the base 2. The head of the second connecting rod 9 is located at the top of the stabilizing plate 8. When the second connecting rod 9 is turned, the head of the second connecting rod 9 presses the stabilizing plate 8 to move toward the base 2, thereby achieving the effect of pressing the battery 16. When fixing the battery 16, firstly screw the second connecting rod 9 so that the stabilizing plate 8 presses the battery 16, and then screw the nut on the first connecting rod 7 so that the pressing plate 6 presses the stabilizing plate 8, thereby further improving the pressing effect.

[0046] In this embodiment, the base 2 is provided with a pressing device 10 , and the pressing device 10 is used to press the battery to be tested 16 against the side wall of the placement groove 101 .

[0047] Due to the limitation of the production process, even batteries 16 of the same model may have slight differences in size, which may result in some batteries 16 not being able to fully fit into the seating groove 101. Therefore, by providing a fastener 10, even if there is a gap between the battery 16 and the seating groove 101, the battery 16 can be pressed against the side wall of the seating groove 101 by the fastener 10, thereby achieving a good fixing effect.

[0048] Specifically, the abutment 10 is arranged between two batteries 16 in the same row, so there are five abutments 10 in this embodiment. In this embodiment, the abutment 10 is a commercially available OK clamp, and the two movable clamping blocks of the abutment 10 are set to a shape that matches the shape of the battery 16. In order to enable the abutment 10 to contact the battery 16, a clearance groove is formed in the portion of the fixed block 1 facing the abutment 10, and at the same time, a clearance groove with a structure similar to the clearance groove of the fixed block 1 is also set at the corresponding position of the base 2, so that a part of the side wall of the battery 16 is exposed, so that the abutment 10 can be pressed against the side wall of the battery 16, and the battery 16 is pressed against the side wall of the placement groove 101.

[0049] This embodiment also provides a battery vibration test device, including a vibrator and the above-mentioned battery vibration test clamping tool, and the battery vibration test clamping tool is connected to the vibration output end of the vibrator.

[0050] Specifically, refer to Figure 6 The battery vibration test device includes a substrate 11, a plurality of battery vibration test fixtures are arranged on the top of the substrate 11, and the bottom of the substrate 11 is connected to the output end of the vibrator. The substrate 11 is mounted on the output end of the vibrator (not shown in the figure), so that the entire substrate 11 is driven to vibrate by the vibrator, and then the plurality of battery vibration test fixtures on the substrate 11 can be driven to perform vibration testing together, so as to achieve the effect of performing vibration testing on a large number of batteries 16.

[0051] In order to perform vibration test on the battery 16 from multiple directions, it is necessary that the battery vibration test clamping tool can be fixed on the substrate 11 in multiple postures. Therefore, in this embodiment, a fixing plate 12 is also included; the fixing plate 12 is provided with a plurality of first mounting holes 121 and a second mounting hole 122, the battery vibration test clamping tool is provided with a plurality of third mounting holes 13, and the substrate 11 is provided with a plurality of positioning holes 111; the fixing plate 12 and the battery vibration test clamping tool are connected by fasteners passing through the second mounting hole 122 and the third mounting hole 13; the fixing plate 12 and the substrate 11 are connected by fasteners passing through the first mounting hole 121 and the positioning hole 111.

[0052] Specifically, refer to Figure 6 The fixing plate 12 is formed by bending a rectangular plate 90 degrees along the width direction. The third mounting holes 13 are provided on two opposite side walls in the length direction of the base 2. Each base 2 is connected to two fixing plates 12. The two fixing plates 12 sandwich the base 2 in the middle, thereby stably fixing the base 2 on the substrate 11. There are multiple third mounting holes 13 on each side wall of the base 2, and multiple second mounting holes 122 on the fixing plate 12. In this way, even if the base 2 is rotated and changes its posture, some of the second mounting holes 122 can correspond to the third mounting holes 13, so that the base 2 can still be connected to the fixing plate 12. For example, Figure 6 In the figure, the battery vibration test fixture of part A is in the state of performing a Z-axis vibration test of the battery 16, and the battery vibration test fixture of part B is in the state of performing an X-axis vibration test of the battery 16. The substrate 11 is covered with positioning holes 111, so that the fixing plate 12 can be installed at any position of the substrate 11, and the battery vibration test fixture can be installed at any position of the substrate 11, which is also convenient for changing the posture of the battery vibration test fixture. In this embodiment, the fastener is a bolt.

[0053] In this embodiment, in order to further improve the stability of the battery vibration test fixture installed on the substrate 11, refer to Figure 6 , a third connecting rod 14 and a pressure column 15 are also provided. Each battery vibration test clamping tool corresponds to two third connecting rods 14, and the third connecting rod 14 is arranged on the side of each fixed plate 12 away from the base 2. Each battery vibration test clamping tool corresponds to a pressure column 15, and each pressure column 15 is provided with two slots along its own length direction, and a third connecting rod 14 is passed through each slot, and the pressure column 15 is located above the battery vibration test clamping tool. The third connecting rod 14 is a screw rod, and the third connecting rod 14 is inserted into the positioning hole 111 of the substrate 11. A nut is also passed through the third connecting rod 14 through threaded cooperation, and the nut is located above the pressure column 15. By screwing the nut, the nut presses the pressure column 15 against the battery vibration test clamping tool, thereby achieving the effect of pressing the battery vibration test clamping tool on the substrate 11.
