[0027] This utility model provides a battery clamp according to Embodiment 1. Please refer to [link to embodiment 1]. Figures 1 to 3 As shown, Figure 1 This is a schematic diagram of the structure of a battery clamp provided in an embodiment of the present invention. Figure 2 This is a schematic diagram of the structure of a soft-pack battery 7 in a battery clamp provided by an embodiment of this utility model. Figure 3 This is a schematic diagram of the structure of the middle clamping plate 2 of a battery clamping device according to an embodiment of the present invention. The battery clamping device provided in this embodiment includes a top clamping plate 1, a middle clamping plate 2, a bottom clamping plate 3, a fastener 4, a bushing 5, and a pressure sensor 6. The top clamping plate 1 has a first through hole 11, and the middle clamping plate 2 has a second through hole 21. The fastener 4 passes through the first through hole 11 and is threadedly connected to the bushing 5. The bushing 5 passes through the second through hole 21 and is fixedly connected to the bottom clamping plate 3, and the bushing 5 is slidably connected to the middle clamping plate 2. The pressure sensor 6 is disposed on the bottom clamping plate 3 and is in contact with the middle clamping plate 2. A clamping space 22 is formed between the top clamping plate 1 and the middle clamping plate 2, and the clamping space 22 is used to place a soft-pack battery 7.

[0028] The inside of the clamping space 22 has a space for accommodating the soft package battery 7, the soft package battery 7 can be placed in the inside of the clamping space 22, the middle layer of the clamping plate 2 provides support for the soft package battery 7 in the inside of the clamping space 22, the top layer of the clamping plate 1 and the middle layer of the clamping plate 2 can slide along the length extension direction of the shaft sleeve 5, after the fastener 4 is screwed with the shaft sleeve 5, the spacing between the middle layer of the clamping plate 2 and the top layer of the clamping plate 1 can be fine-tuned by rotating the fastener 4, that is, after the soft package battery 7 is placed on the middle layer of the clamping plate 2, the fastener 4 is rotated to press the top layer of the clamping plate 1 on the soft package battery 7 on the middle layer of the clamping plate 2, and the soft package battery 7 is pressed. When the soft package battery 7 is charged and discharged, the expansion force of the soft package battery 7 will push the middle layer of the clamping plate 2 along the length extension direction of the shaft sleeve 5 to continuously apply pressure to the pressure sensor 6 on the bottom layer of the clamping plate 3, and the pressure sensor 6 will collect the pressure data in real time. The top layer of the clamping plate 1, the middle layer of the clamping plate 2 and the bottom layer of the clamping plate 3 can be made of stainless steel.

[0029] In the embodiment, the fastener 4 is screwed with the shaft sleeve 5 through the first through hole 11 in the top layer of the clamping plate 1, the shaft sleeve 5 is fixedly connected with the bottom layer of the clamping plate 3 through the second through hole 21 in the middle layer of the clamping plate 2, and the shaft sleeve 5 is slidably connected with the middle layer of the clamping plate 2. The pressure sensor 6 is arranged on the bottom layer of the clamping plate 3, and the pressure sensor 6 is in contact with the middle layer of the clamping plate 2. The clamping space 22 is formed between the top layer of the clamping plate 1 and the middle layer of the clamping plate 2, and the soft package battery 7 can be placed in the inside of the clamping space 22. In this way, the fastener 4 adjusts the spacing between the top layer of the clamping plate 1 and the middle layer of the clamping plate 2 to control the size of the clamping space 22 to adapt to soft package batteries 7 of different sizes, and after the soft package battery 7 on the middle layer of the clamping plate 2 is pressed, the middle layer of the clamping plate 2 and the top layer of the clamping plate 1 will ensure that the soft package battery 7 is uniformly clamped. At the same time, the middle layer of the clamping plate 2 with the soft package battery 7 is in contact with the pressure sensor 6 on the bottom layer of the clamping plate 3, at which time the initial pressure value measured by the pressure sensor 6 is recorded in advance. Then the soft package battery 7 on the middle layer of the clamping plate 2 is charged and discharged, and the soft package battery 7 will generate pressure on the middle layer of the clamping plate 2 due to expansion during the charging and discharging process of the soft package battery 7. The pressure data is collected in real time by the pressure sensor 6, and then the clamping pressure is uniform during the test of the small soft package battery 7, and the real-time collection of the pressure data can be carried out at the same time. Thus, the technical effect of making the clamping pressure uniform during the test of the small soft package battery 7 and enabling the real-time collection of the pressure data at the same time is achieved.

[0030] As an implementation, the number of the shaft sleeves 5 can be four, the number of the fasteners 4 can be four, the number of the first through holes 11 can be four, the number of the second through holes 21 can be four, the four fasteners 4 and the four shaft sleeves 5 are respectively arranged one by one, the fastener 4 is screwed with the corresponding shaft sleeve 5 after penetrating the corresponding first through hole 11, and the shaft sleeve 5 is fixedly connected with the bottom layer 3 after penetrating the corresponding second through hole 21. When the soft package battery 7 is placed in the clamping space 22 formed by the middle layer 2 and the top layer 1, the clamping pressure can be uniformly applied to the soft package battery 7 by adjusting the tightness of the four fasteners 4. Due to the uniform distribution of the four shaft sleeves 5 and the fasteners 4, the clamping force is uniformly distributed on the surface of the soft package battery 7, avoiding the situation that the local pressure is too large or too small. At the same time, by adjusting the tightness of the four fasteners 4, the distance between the top layer 1 and the middle layer 2 can be accurately controlled, so as to adapt to soft package batteries 7 of different sizes.

[0031] In some embodiments, the four shaft sleeves 5 are equally spaced and parallel to each other, and the shaft sleeves 5 are perpendicular to the middle layer 2. Due to the equal spacing and parallel distribution of the shaft sleeves 5, the distance between the top layer 1 and the middle layer 2 is more uniform when adjusted, which can improve the uniformity of the clamping force. At the same time, the overall rigidity and stability of the battery clamp are improved, so that a stable clamping effect can be maintained during long-term use.

[0032] In some embodiments, the middle layer 2 is rectangular, and the four second through holes 21 are respectively arranged in the four corner regions 23 of the middle layer 2. The corner region 23 of the middle layer 2 refers to the region near the corner of the middle layer 2. When the middle layer 2 is a square, the corner region 23 of the middle layer 2 refers to the region near the right angle of the middle layer 2. Due to the rectangular shape of the middle layer 2 and the location of the four second through holes 21 in the corner regions 23, the middle layer 2 can more evenly distribute the clamping force when clamping the soft package battery 7. At the same time, the anti-deformation ability of the middle layer 2 is improved, so that a stable clamping effect and good service life can be maintained during long-term use.

[0033] In some embodiments, the soft package battery 7 is placed in the central region 24 of the middle layer 2, and the central region 24 of the middle layer 2 refers to the geometric center position of the middle layer 2. When the middle layer 2 is a square, the central region 24 of the middle layer 2 refers to the center position of the middle layer 2. Due to the placement of the soft package battery 7 in the central region 24 of the middle layer 2, the soft package battery 7 can more evenly receive the clamping force from the top layer 1 and the middle layer 2 during clamping. At the same time, it avoids that the soft package battery 7 receives excessive pressure from the edge region during clamping, which is beneficial to improve the service life and safety of the soft package battery 7.

[0034] In some embodiments, the battery clamping device provided by the first embodiment of the present application further comprises a silica gel non-slip pad 8, the silica gel non-slip pad 8 is arranged on the middle layer clamping plate 2, and the soft package battery 7 is placed on the silica gel non-slip pad 8. The silica gel non-slip pad 8 can increase the friction of the soft package battery 7, so that the soft package battery 7 is prevented from being displaced or falling during the movement of the battery clamping device. The silica gel non-slip pad 8 also makes the soft package battery 7 more stable during clamping, and is not easy to slide or displace. Meanwhile, the silica gel non-slip pad 8 also has a certain buffering effect, and can reduce the impact and vibration of the soft package battery 7 during clamping. In addition, the wear resistance and corrosion resistance of the silica gel non-slip pad 8 also prolong the service life of the battery clamping device.

[0035] In some embodiments, a plurality of convex points can be arranged on the middle layer clamping plate 2, and the convex points protrude from the middle layer clamping plate 2 towards the top layer clamping plate 1. Those skilled in the art will understand that the specific structure of the convex points in the battery clamping device provided by the first embodiment of the present application is not limited, as long as the soft package battery 7 is placed behind the plurality of convex points, the friction between the soft package battery 7 and the middle layer clamping plate 2 can be increased, and the soft package battery 7 is prevented from being displaced or falling during the movement of the battery clamping device. When the soft package battery 7 is placed in the clamping space 22 between the top layer clamping plate 1 and the middle layer clamping plate 2, the middle layer clamping plate 2 can be moved towards the top layer clamping plate 1 by adjusting the fastener 4, so as to clamp the soft package battery 7. At this time, since the plurality of convex points are arranged on the middle layer clamping plate 2, the convex points will be in contact with the surface of the soft package battery 7, and will play a role in dispersing the clamping force. Meanwhile, the arrangement of the convex points can also increase the friction between the middle layer clamping plate 2 and the soft package battery 7, so as to prevent the soft package battery 7 from sliding or displacing during clamping. During the charging and discharging process of the soft package battery 7, the pressure generated by the expansion of the battery will be transmitted to the middle layer clamping plate 2 through the convex points, and then be collected by the pressure sensor 6 in real time. The plurality of convex points can be uniformly distributed, so that the clamping pressure is more uniform, which is conducive to improving the accuracy and reliability of the test.

[0036] In some embodiments, the projection of the pressure sensor 6 along the length extension direction of the shaft sleeve 5 on the middle layer clamping plate 2 is located on the middle layer clamping plate 2, so that the pressure sensor 6 can always be in contact with the middle layer clamping plate 2. During the working process of the battery clamping device, when the soft package battery 7 is clamped, the pressure generated by the expansion of the soft package battery 7 during the charging and discharging process will be transmitted to the pressure sensor 6 through the middle layer clamping plate 2. The pressure sensor 6 can accurately measure the pressure change of the middle layer clamping plate 2. Since the pressure sensor 6 can collect data in real time, the expansion of the soft package battery 7 can be monitored in real time, which provides strong support for the research and development and production of batteries.

[0037] In some embodiments, the fastener 4 comprises a screw rod and a limiting head, the screw rod is screwed with the shaft sleeve 5 after penetrating through the first through hole 11, and the limiting head is connected with the screw rod, and the top clamping plate 1 is located between the limiting head and the shaft sleeve 5. Those skilled in the art can understand that the specific structure of the limiting head in the battery clamping device provided in the embodiment one of the utility model is not limited, as long as the screw rod is screwed with the shaft sleeve 5 after penetrating through the first through hole 11, and the limiting head can drive the top clamping plate 1 to move towards the direction of approaching the middle clamping plate 2 when the screw rod rotates. In the working process of the battery clamping device, the spacing between the top clamping plate 1 and the middle clamping plate 2 can be controlled by adjusting the rotation degree of the screw rod, so as to realize the clamping of the soft package battery 7. The limiting head can limit the movement range of the top clamping plate 1, prevent the top clamping plate 1 from moving excessively or being damaged during clamping, not only can improve the stability and durability of the battery clamping device, but also can ensure that the soft package battery 7 can be clamped uniformly and stably during clamping. At the same time, the limiting head can conveniently control the size of the clamping force, and the screw rod is driven to rotate by rotating the limiting head, which is helpful to improve the accuracy and reliability of the test.

The utility model embodiment two provides a battery clamping system, which comprises the above-mentioned battery clamping device, and further comprises a charging device 9 and a PC end 91, the charging device 9 is connected with the pressure sensor 6 and the soft package battery 7 respectively, the pressure sensor 6 is powered through the charging device 9, and the soft package battery 7 can be charged and discharged through the charging device 9, and the pole lug of the soft package battery 7 can be extended from between the two adjacent shaft sleeves 5 and electrically connected with the charging device 9. After the PC end 91 is connected with the pressure sensor 6, the PC end 91 can receive the pressure data collected by the pressure sensor 6 in real time, and the pressure data is analyzed and processed through the PC end 91.

[0040] The utility model provides a battery clamping system, through fastener 4 passes through the first through hole 11 of top layer clamping plate 1 and the threaded connection of shaft sleeve 5, shaft sleeve 5 passes through the fixed connection of second through hole 21 of middle layer clamping plate 2 and bottom layer clamping plate 3, and shaft sleeve 5 and middle layer clamping plate 2 sliding connection. Pressure sensor 6 sets up in bottom layer clamping plate 3, and pressure sensor 6 and middle layer clamping plate 2 mutual contact. Formed with the clamping space 22 between top layer clamping plate 1 and middle layer clamping plate 2, and soft package battery 7 can be placed in the inside of clamping space 22. Fastener 4 adjusts the spacing between top layer clamping plate 1 and middle layer clamping plate 2, controls the size of clamping space 22, to adapt to the soft package battery 7 of different size, and after the compression of the soft package battery 7 of being located in middle layer clamping plate 2, middle layer clamping plate 2 and top layer clamping plate 1 will ensure that the soft package battery 7 is applied to the clamping pressure. The middle layer clamping plate 2 of placing soft package battery 7 and the pressure sensor 6 on bottom layer clamping plate 3 contact each other, at this time, the initial pressure value measured by pressure sensor 6 is recorded in advance.
