Furthermore, the present invention also relates to a battery testing cabinet including the simple jig for testing cylindrical batteries. Background Art

[0002] When developing battery cell products and analyzing competitive products, it is usually necessary to conduct cycle, rate, low temperature, high temperature and other tests. The number of test battery samples and test types are very large. Especially in the testing of cylindrical battery cells, a pin-type battery test cabinet is generally used for testing. During the specific operation, the battery test cabinet needs to be adjusted according to the height of the battery to be tested, the spacing between the batteries required for the test, etc. When using the existing battery test cabinet to test several batteries, the operator is often required to place each battery into the battery test cabinet one by one. The battery loading efficiency is low, especially when conducting high and low temperature tests. Due to the long battery loading time, the first battery and the last battery have inconsistent standing time under high and low temperature conditions. At the same time, the battery test cabinet is open for a long time. After the battery is loaded, the temperature inside the battery test cabinet is greatly different from the set temperature. It takes a long time to heat up or cool down, resulting in a shortened battery test cabinet life, energy waste, and increased costs.

[0003] In summary, how to improve the efficiency of the upper battery is an urgent problem to be solved by those skilled in the art. Utility Model Content

[0033] like Figure 1 and Figure 2 As shown, several first fixing parts 5 are provided on the first jig body 1 in the horizontal direction. Similarly, several second fixing parts 6 are provided on the second jig body 2 in the horizontal direction. In coordination, the left end of the first jig body 1 and the left end of the second jig body 2 are connected by a connecting member 3, so that they can be opened and closed. The right end of the first jig body 1 and the right end of the second jig body 2 can be fixedly connected or opened by a locking member 4 to achieve locking or unlocking.

[0034] In use, the locking piece 4 is opened to achieve unlocking, the other of the first jig body 1 and the second jig body 2 is pushed to make the two open, the jig is placed on the table top, a plurality of cylindrical batteries are placed one by one in the corresponding first fixing part 5 on the first jig body 1, the second jig body 2 is pushed to make the first jig body 1 and the second jig body 2 in a closed state, the right end of the first jig body 1 and the right end of the second jig body 2 are fixedly connected through the locking piece 4, so as to achieve locking and make the first jig body 1 and the second jig body 2 unable to be opened at will, at this time, the opposite first fixing part 5 and the second fixing part 6 can clamp the cylindrical battery placed in the first fixing part 5, and the operation of the lower battery is opposite to the above process. In this way, the jig can fix a plurality of cylindrical batteries at the same time, greatly simplifying the operation steps of the upper battery, effectively improving the efficiency of the upper battery, and the time spent for the battery test cabinet using the jig to do the rate test is 1 / 6 of the time required for the same test of the related technology, the time spent for the battery test cabinet using the jig to do the low-temperature discharge is much lower than the time required for the same test of the related technology, and the temperature difference between the first battery temperature and the last battery temperature is 1 / 4 of the temperature difference when the same test is performed by the related technology, effectively improving the consistency of the cylindrical battery under high and low temperature test conditions, and being beneficial to reducing the labor cost.

[0035] It should be noted that in use, the cylindrical battery can also be placed in the second fixing part 6 of the second jig body 2 first, and the operation process is the same as the above-mentioned operation process of placing the cylindrical battery in the first fixing part 5 first.

[0036] It should be further noted that the types, numbers and distribution modes of the first fixing part 5 and the second fixing part 6 are not limited, for example, the first fixing part 5 and the second fixing part 6 can adopt rectangular grooves or trapezoidal grooves, and the first fixing part 5 and the second fixing part 6 can be the same or different, as long as the cylindrical battery can be placed in the corresponding first fixing part 5 or second fixing part 6 and positioned; a plurality of first fixing parts 5 and a plurality of second fixing parts 6 can be arranged in a matrix or in a ring, as long as a plurality of cylindrical batteries can be placed in the corresponding first fixing part 5 or second fixing part 6 to clamp the corresponding cylindrical battery through the opposite first fixing part 5 and second fixing part 6.

[0037] On the basis of the above-mentioned embodiments, the tail end of the first fixing part 5 and the tail end of the second fixing part 6 are connected to the corresponding first jig body 1 and second jig body 2, and the head end has a limiting groove for clamping the cylindrical battery; a plurality of first fixing parts 5 are slidably arranged on the first jig body 1 to adjust the spacing between the plurality of first fixing parts 5; a plurality of second fixing parts 6 are slidably arranged on the second jig body 2 to adjust the spacing between the plurality of second fixing parts 6.

[0038] As Figure 2As shown, in this embodiment, the first fixing portion 5 is independent of the first fixture body 1, and the head end of the first fixing portion 5 has a limiting groove such as a rectangular groove or a trapezoidal groove, so that the cylindrical battery can be placed in the limiting groove to achieve positioning of the cylindrical battery, and a guide structure is provided on the first fixture body 1. The guide structure can adopt a slide groove or include two rows of limiting rods, etc., to slide with the tail end of the first fixing portion 5, and the first fixing portion 5 can be slid as needed to move it to different positions of the first fixture body 1 to achieve adjustment of the spacing between several first fixing portions 5.

[0039] Similarly, the second fixing part 6 is independent of the second fixture body 2, and the head end of the second fixing part 6 has a limiting groove such as a rectangular groove or a trapezoidal groove, so that the cylindrical battery can be placed in the limiting groove to realize the positioning of the cylindrical battery, and a guiding structure is provided on the second fixture body 2. The guiding structure can adopt a slide groove or include two rows of limiting rods, etc., to slide with the tail end of the second fixing part 6. The second fixing part 6 can be slid as needed to move it to different positions of the second fixture body 2 to realize the adjustment of the spacing between several second fixing parts 6.

[0040] With such a configuration, the fixture is conducive to meeting different testing requirements.

[0041] On the basis of the above embodiment, the inner wall of the limiting groove has an elastic layer, and the elastic layer can be made of a rubber gasket or a cotton sheet, etc. Such a setting is conducive to clamping the cylindrical battery and preventing the cylindrical battery from slipping.

[0042] On the basis of the above embodiment, the first fixture body 1 and the second fixture body 2 are arranged to be openable and closable with the X direction as the axis, and the limiting grooves of the first fixing part 5 and the limiting grooves of the second fixing part 6 both extend along the X direction.

Correspondingly, the limiting groove of the first fixing part 5 and the limiting groove of the second fixing part 6 both extend along the X direction, so that several cylindrical batteries extending along the X direction can be clamped between the corresponding first fixing part 5 and the second fixing part 6. Such an arrangement is conducive to reducing the volume of the fixture.

[0044] Of course, in other specific embodiments, the limiting groove of the first fixing portion 5 and the limiting groove of the second fixing portion 6 may also extend in a direction perpendicular to the X direction.
