For those skilled in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0030] Based on the problem that the new energy battery test structure pointed out in the background technology is complex and cannot meet the test of batteries 9 of different lengths on the same device. The utility model provides a battery test adapter box, which aims to configure a guide rod 2 that can be moved and reset by a first elastic member 10 in the box body 1, and a test probe 3 and an adapter probe 4 configured at both ends of the guide rod 2, and multiple detachable box bodies 1 configured on the combination handle 6, so that when it is necessary to test batteries 9 of different lengths, it is only necessary to lift the combination handle 6 to take out the corresponding box body 1, and the battery 9 of different lengths can be tested, which is convenient to operate and simple in structure.

[0031] like Figures 1 to 6 As shown, the battery test adapter box of the utility model comprises: a box body 1, the box body 1 has a first end 101 and a second end 102 opposite to each other, and a guide rod 2 is slidably configured on the side of the box body 1; a test probe 3 and a transfer probe 4, the test probe 3 and the transfer probe 4 are respectively configured at the two ends of the guide rod 2, the test probe 3 is relatively located at the first end 101 of the box body 1, and the transfer probe 4 is relatively located at the second end 102 of the box body 1, and the test probe 3 and the transfer probe 4 are connected by a metal wire 5; a combined handle 6, the top of the combined handle 6 forms a handle portion, and the bottom forms an assembly portion, and the assembly portion is at least detachably installed with one set of box bodies 1.

[0032] See also Figures 2 to 5 The first end 101 and the second end 102 of the box body 1 are respectively formed with a receiving groove 105 for accommodating the test probe 3 and the adapter probe 4. The test probe 3 and the adapter probe 4 can slide in the receiving groove 105 at the first end 101 and the second end 102, and the receiving groove 105 is arranged in a U-shaped structure.

[0033] See also Figure 5 There are two guide rods 2, which are arranged from top to bottom. The guide rods 2 are limited on the box body 1 by the limit ring 7, so that when the test probe 3 and the transfer probe 4 move with the guide rod 2, they can only move in the direction from the first end 101 to the second end 102 of the box body 1. When the test probe 3 and the transfer probe 4 move, the metal wire 5 moves synchronously. It should be noted that the metal wire 5 is one of copper wire, silver wire and gold wire. The test probe 3 includes a current test probe and a voltage test probe, and the transfer probe 4 includes a current transfer probe and a voltage transfer probe.

[0034] See also Figure 1 , Figure 2 The assembly portion of the combination handle 6 is installed with 16 groups of box bodies 1. In other possible implementations, fewer box bodies 1 such as 10 groups or 5 groups may be installed, or more box bodies 1 such as 20 groups or 25 groups may be installed, without specific limitation.

[0035] See also Figure 1 The battery test adapter box of the utility model is used in conjunction with a test tray 8. The test tray 8 includes a first installation area 81 for placing a battery 9 and a second installation area 82 for placing an adapter box. When the battery 9 is placed in the first installation area 81 and the adapter box is placed in the second installation area 82, the box body 1 in the adapter box corresponds to the battery 9 one by one.

[0036] When testing batteries 9 of the same type but different lengths, there are two situations:

[0037] Case 1: The length of the battery 91 is the length defined by the first installation area 81 , and the length of the battery 92 is the cumulative length of the first installation area 81 and the second installation area 82 .

[0038] With respect to the problem in situation 1, when testing battery 91 and battery 92, it is only necessary to remove the adapter box corresponding to the battery 92 on the combination handle 6, and then connect the whole to the testing machine for testing.

[0039] Case 2: The length of battery 91 is the length limited by the first installation area 81, the length of battery 92 is the cumulative length of the first installation area 81 and the second installation area 82, the length of battery 93 is less than the length limited by the first installation area 81, and the length of battery 94 is greater than the length limited by the first installation area 81 but less than the cumulative length of the first installation area 81 and the second installation area 82.

[0040] In response to the problem in situation two, when testing batteries 91 to 94, the box body 1 corresponding to the battery 92 on the combination handle 6 is removed, and at the same time, the box body 1 corresponding to the battery 93 is controlled to extend toward the first installation area 81, and the box body 1 corresponding to the battery 94 is controlled to retract in the direction away from the first installation area 81, so as to match the lengths of batteries 91 to 94 and meet the testing of batteries 9 of different lengths by the same test tray 8, thereby improving the testing efficiency of the present application and improving the scope of application of the present application.

[0041] In one or more embodiments, a first elastic member 10 is sleeved on the guide rod 2. With the help of the elastic force of the first elastic member 10, when the adapter probe 4 and the test probe 3 are in a static position, the adapter probe 4 is located at the second end 102 of the box body 1, and the test probe 3 is located at the first end 101 of the box body 1.

[0042] See also Figures 2 to 5 The adapter probe 4 is connected to the end of the guide rod 2 through the adapter base 41, and the two ends of the first elastic member 10 are respectively installed on the limit ring 7 and the adapter base 41.

[0043] In the initial state, under the action of the first elastic member 10 , the test probe 3 is located at the first end 101 of the box body 1 , and the adapter probe 4 is located at the second end 102 of the box body 1 .

[0044] By pushing the guide rod 2 toward the first end 101 of the box body 1 to compress the first elastic member 10 and extend the test probe 3 out of the first end 101 of the box body 1, the battery 9 whose length is less than the length specified by the first installation area 81 can be tested; by pulling the guide rod 2 toward the second end 102 of the box body 1 to put the second elastic member 11 in a stretched state, the test probe 3 retreats to the inside of the first end 101, and the adapter probe 4 extends out of the second end 102 of the box body 1, the battery 9 whose length is greater than the length specified by the first installation area 81 but less than the cumulative length of the first installation area 81 and the second installation area 82 can be tested; by adding the first elastic member 10, after the performance test of the battery 9 is completed, the guide rod 2, the test probe 3 and the adapter probe 4 can be returned to their original positions, which is convenient for the next performance test of the battery 9 and has practicality.

[0045] In one or more embodiments, the test probe 3 is mounted on the first end 101 of the guide rod 2 via a test base 31 , and the test probe 3 is relatively movably disposed on the test base 31 via a second elastic member 11 .

[0046] See also Figure 5 In the initial state, under the action of the second elastic member 11, the test probe 3 extends relatively out of the test base 31. In this way, the test probe 3 can achieve elastic contact with the battery 9, reducing the damage of the test probe 3 to the battery 9, while extending the possibility of damage to the test probe 3 and extending the service life of the test probe 3.

[0047] In one or more embodiments, the guide rod 2 and the test probe 3 and the adapter probe 4 slide forward and backward in the straight line direction from the first end 101 to the second end 102 of the box body 1 by a distance of 0-15 mm.

[0048] See also Figure 5 The guide rod 2 and the test probe 3 and the adapter probe 4 slide synchronously relative to the box body 1, that is, the test probe 3 extends out of the first end 101 of the box body 1 by 0-15mm, and the adapter probe 4 extends out of the second end 102 of the box body 1 by 0-15mm.

[0049] When the test probe 3 needs to extend from the first end 101 of the box body 1 by 0-15mm, it is to detect the battery 9 whose length is less than the length specified by the first installation area 81; when the adapter probe 4 extends from the second end 102 of the box body 1 by 0-15mm, the corresponding distance of the test probe 3 returning to the receiving groove 105 of the box body 1 is 0-15mm, and at this time, the battery 9 whose length is greater than the length specified by the first installation area 81 but less than the cumulative length of the first installation area 81 and the second installation area 82 can be tested, and 0-15mm is the variable for testing batteries 9 of different lengths in this application. In this way, the application can adapt to batteries 9 of different lengths and improve the efficiency of battery 9 detection.

[0050] In one or more embodiments, the second end 102 of the box body 1 is configured with a driving device for pushing the guide rod 2 to move forward and backward in a straight line direction from the first end 101 to the second end 102 of the box body 1 .

[0051] The driving device is not shown in the drawings, and the driving device may be a driving cylinder. The driving end of the driving device is not fixedly connected to the adapter base 41, and the driving end of the driving device is detachably connected to the adapter base 41 so that the adapter probe can extend out of the second end 102 of the box body 1.

[0052] When it is necessary to push the test probe out of the first end 101 of the box body 1 to detect a battery 9 whose length is shorter than that specified by the first installation area 81, the extended shaft end of the driving cylinder is controlled to abut against the adapter base 41; when the length of the battery 9 to be detected is longer than the length specified by the first installation area 81 but shorter than the cumulative length of the first installation area 81 and the second installation area 82, there is no need to drive the cylinder to work, and the test probe only needs to be pressed against the side of the battery 9 to put the first elastic member 10 in a stretched state. The structure is simple and the operation is convenient.

[0053] It should be noted that in other possible implementations, the driving device may be omitted.

[0054] In one or more embodiments, the first elastic member 10 is a spring or elastic steel.

[0055] In one or more embodiments, the box body 1 is connected to the combined handle 6 by bolts.

[0056] See also Figure 2 The combination handle 6 is made of hard plastic, and each combination handle 6 is equipped with 16 sets of box bodies 1. The box body 1 is connected to the combination handle 6 by bolts, so that the box body 1 can be quickly installed or removed from the combination handle 6, which has a certain convenience.

[0057] In one or more embodiments, a side panel 12 for shielding the test probe 3 , the transfer probe 4 and the guide rod 2 is disposed on the side of the box body 1 .

[0058] See also Figures 4 to 6 The two ends of the side panel 12 have accommodating grooves 105 that are consistent with the two ends of the box body 1. The side panel 12 and the box body 1 form a complete structure for placing the guide rod 2, the test probe 3 and the adapter probe 4. The side panel 12 can reduce the risk of damage to the copper wire connecting the test probe 3 and the adapter probe 4, thereby extending the service life of the adapter box.

[0059] See also Figure 5A through-going snap-in window 103 is provided on the upper portion of the box body 1, a flange 104 is formed in the snap-in window 103, a buckle 121 is formed on the surface of the side panel 12 corresponding to the snap-in window 103, the buckle 121 can extend into the snap-in window 103 and buckle on the flange 104, in addition, the side panel 12 is connected to the box body 1 at the lower position of the guide rod 2 by bolts; the way in which the side panel 12 is connected to the box body 1 by the buckle 121 and the bolts can improve the connection efficiency between the two while ensuring the connection strength between the side panel 12 and the box body 1.

[0060] In one or more embodiments, the box body 1 and the side plate 12 are both made of hard plastic. Through this arrangement, the overall weight of the adapter box can be reduced, making it easier for staff to take the adapter box, thereby improving the convenience of use of the present application.

[0061] In one or more embodiments, the total thickness of the box body 1 and the side panels 12 is 20-30 mm, the length of the box body 1 is 260-280 mm, and the width of the box body 1 is 110 mm-130 mm. In a specific embodiment, the total thickness of the box body 1 and the side panels 12 is 26 mm, the length of the box body 1 is 275 mm, and the width of the box body 1 is 120 mm.
