[0034] This application provides a discharge testing fixture. It should be noted that the discharge testing fixture in this application can be used for discharge testing of various devices under test (DUTs). DUTs generally have a battery, and the discharge testing fixture is used to test the charge level of the DUT, facilitating the determination of the number of times the DUT can be used.

[0035] It should be noted that the type of battery is not limited in this embodiment. For example, the battery can be a zinc-manganese dry cell battery, an alkaline zinc-manganese battery, a lithium battery, etc.

[0036] The discharge testing fixture 100 provided in this embodiment can detect the number of discharges of the test piece 200.

[0037] Based on this, refer to Figure 1 This application also provides a discharge testing fixture 100, including a mounting base 1, a clamping assembly 2, a discharge assembly 3, and a power display assembly 4.

[0038] Reference Figure 1 and Figure 2 To better illustrate the discharge test fixture 100 provided in this application embodiment, the clamping component 2 is disposed on the mounting base 1 for fixing the test piece 200. During the discharge test, the tester does not need to manually support the test piece 200 and can perform other work, reducing the labor cost of discharge testing.

[0039] Reference Figure 1 and Figure 2 The discharge assembly 3 includes an electrical connector 31 and a discharge component 32. Both the electrical connector 31 and the discharge component 32 are mounted on the mounting base 1. The electrical connector 31 is electrically connected to both the device under test 200 and the discharge component 32. The electrical connector 31 enables the electrical connection between the device under test 200 and the discharge component 32. When the discharge component 32 is working, it consumes the power of the device under test 200 to achieve the discharge of the device under test 200.

[0040] Reference Figure 1 and Figure 2 The power display component 4 is mounted on the mounting base 1 and is electrically connected to the electrical connector 31. It is used to display the power of the device under test 200. The discharge amount of the device under test 200 can be seen intuitively, and the initial power of the device under test 200 can be read before the test, avoiding repeated testing of the same device under test 200.

[0041] Furthermore, in this embodiment, the type of discharge element 32 is not limited, as long as it can achieve the discharge of the device under test 200. For example, the discharge element 32 can be a motor.

[0042] The device under test 200 is equipped with a battery 201, and the discharge device 32 is used to release the charge of the battery 201.

[0043] In this embodiment, the device under test 200 is a Bluetooth key battery 201, and the power display component 4 is an electronic display screen.

[0044] According to the discharge testing fixture 100 of this application, the device under test 200 can be fixed by setting the clamping component 2. During the discharge testing process, the tester does not need to manually support the device under test 200, and can perform other tasks, reducing the labor cost of discharge testing. At the same time, the power display component 4 is electrically connected to the electrical connector 31 to display the power of the device under test 200. The initial power of the device under test 200 can be read before testing, avoiding repeated testing of the same device under test 200.

[0045] In this application, the wiring harness connecting the electrical connector 31 to the power display component 4 and the discharge component 32 can be located inside or outside the mounting base 1 to achieve electrical connection between the electrical connector 31 and the power display component 4 and the discharge component 32.

[0046] In some embodiments of this application, reference is made to Figure 1 and Figure 2 The mounting base 1 is provided with a clearance hole 11, which is along the thickness direction of the mounting base 1 (e.g., Figure 1 The second direction shown penetrates through the mounting base 1, and the test piece 200 is disposed within the clearance hole 11, so that when the discharge test fixture 100 is working, the test piece 200 is disposed within the clearance hole 11, which can reduce the overall volume of the discharge test fixture 100. The two end faces in the thickness direction of the mounting base 1 are the first end face 12 and the second end face 13, respectively. The clamping assembly 2 is disposed in the width direction of the mounting base 1 (e.g., the second direction shown). Figure 2 The two ends of the third direction shown are used to fix the test piece 200.

[0047] Furthermore, in some embodiments of this application, reference is made to... Figure 2 and Figure 4 Electrical connector 31 is located along the length of mounting base 1 (e.g., Figure 1 At one end of the first direction shown, the electrical connector 31 includes a connecting component 311 and a connecting pin 312. The connecting component 311 is connected to the end of the mounting base 1 near the first end face 12. The connecting pin 312 is located on the side of the mounting base 1 opposite to the second end face 13, thus connecting the connecting pin 312 to the mounting base 1. One end of the connecting pin 312 along its length is connected to the connecting component 311, and the other end extends into the clearance hole 11 for electrical connection with the device under test 200. It can be understood that the device under test 200 is located in the clearance hole 11, and the connecting pin 312 extends deep into the clearance hole 11, which facilitates the electrical connection between the device under test 200 and the connecting pin 312, and further facilitates the electrical connection between the device under test 200 and the discharge component 32 and the power display component 4.

[0048] In some embodiments of this application, reference is made to Figure 1 and Figure 4 The connecting pin 312 includes a first elastic element 3121 and a pin 3122. The first elastic element 3121 extends along the length direction of the mounting base 1. One end of the first elastic element 3121 in the length direction is connected to the connecting component 311, and the other end is located on the side of the clearance hole 11 opposite to the second end face 13. The pin 3122 extends along the thickness direction of the mounting base 1. The pin 3122 is connected to the end of the first elastic element 3121 opposite to the connecting component 311 and extends into the clearance hole 11 for electrical connection with the test piece 200.

[0049] It is understandable that the first elastic element 3121 has a certain elasticity. When the connecting pin 312 is electrically connected to the test piece 200, the first elastic element 3121 can easily adapt to test pieces 200 of different sizes, increasing the compatibility of the discharge test fixture 100.

[0050] In some embodiments of this application, reference is made to Figure 1 and Figure 4 The mounting base 1 has a mounting groove 14 near the clearance hole 11. The mounting groove 14 has a first opening 141 on the first end face 12 and a second opening 142 on the peripheral wall of the clearance hole 11. The first opening 141 is spaced apart from the clearance hole 11, and the second opening 142 is spaced apart from the first end face 12. The connecting assembly 311 includes a connecting stud 3111 and a fastening nut 3112. The connecting assembly 311 extends along the thickness direction of the mounting base 1. At least a portion of the connecting stud 3111 is located in the mounting groove 14. There are two fastening nuts 3112. The fastening nuts 3112 are sleeved on the connecting stud 3111. One of the two fastening nuts 3112 abuts against the first end face 12 and is connected to the connecting pin 312. The other is located in the mounting groove 14 and abuts against the side wall of the mounting groove 14 near the first end face 12.

[0051] Understandably, when the discharge test fixture 100 is assembled, after the connecting stud 3111 and the fastening nut 3112 with the connecting pin 312 are engaged, the lower end of the connecting stud 3111 extends into the mounting groove 14 from the first opening 141. The other fastening nut 3112 enters the mounting groove 14 from the second opening 142 and engages with the connecting stud 3111 from the lower end. The lower end of the fastening nut 3112 with the connecting pin 312 abuts against the first end face 12, and the other fastening nut 3112 abuts against the side wall of the mounting groove 14 near the first end face 12. The two fastening nuts 3112 together limit the connecting stud 3111, thereby achieving reliable connection between the electrical connector 31 and the mounting base 1.

[0052] Furthermore, in this embodiment, the type of fastening nut 3112 is not limited, as long as it can achieve the limiting connection of the stud 3111. For example, the fastening nut 3112 can be a square-headed nut.

[0053] In some embodiments of this application, reference is made to Figure 1 and Figure 2 The clearance hole 11 has mounting holes 111 at both ends in the width direction. There are two clamping components 2, which are respectively inserted into the two mounting holes 111. It can be understood that the clamping components 2 can clamp the test piece 200 on both sides in the width direction of the mounting base 1, so that the position of the test piece 200 is more reliable. During the discharge test, the tester does not need to manually support the test piece 200, and the tester can perform other tasks, reducing the labor cost of discharge testing.

[0054] In some embodiments of this application, reference is made to Figures 1-3 The clamping assembly 2 includes a clamping member 21 and a second elastic member. At least a portion of the clamping member 21 passes through the mounting hole 111 for clamping the test piece 200. The two second elastic members are used to drive the two clamping members 21 to move toward each other. The clamping member 21 and the second elastic member together limit the test piece 200, making the position of the test piece 200 more reliable.

[0055] Furthermore, referring to Figures 1-3 In some embodiments of this application, the clamping member 21 includes a pin body 211, a connecting part 212, and a fastening part 213. The pin body 211 passes through the mounting hole 111. The connecting part 212 is detachably provided at one end of the insertion clearance hole 11 of the pin body 211 for connecting with the test piece 200. The fastening part 213 is detachably provided at one end of the pin body 211 away from the clearance hole 11. The fastening part 213 abuts against the side wall of the mounting base 1 in the width direction.

[0056] It is understandable that the pin body 211 passes through the mounting hole 111, and the connecting part 212, after being connected to the pin body 211, passes outward from the clearance hole 11 into the mounting hole 111. The fastening part 213 abuts against the wall surface in the width direction of the mounting base 1. The two second elastic members are used to drive the two connecting parts 212 to move towards each other. The two clamping components 2 together limit the test piece 200, making the position of the test piece 200 relatively simple and reliable.

[0057] Furthermore, in this embodiment, the type of fastening part 213 is not limited, as long as it can realize the limiting pin body 211. For example, the fastening part 213 can be a square-headed nut.

[0058] In some embodiments of this application, reference is made to Figures 1-3The end of the connecting part 212 away from the fastening part 213 is provided with a receiving groove 2121. At least a part of the test piece 200 is provided in the receiving groove 2121. The inner wall of the receiving groove 2121 can abut against the test piece 200, thereby increasing the limit of the connecting part 212 on the test piece 200.

[0059] In some embodiments of this application, reference is made to Figure 1 and Figure 2 The mounting base 1 is provided with a limiting groove 15, and the discharge component 32 is located in the limiting groove 15. The limiting groove 15 can limit the discharge component 32 and increase the reliability of the position of the limiting component.

[0060] In this application, reference is made to Figure 5 When the discharge test fixture 100 is used for testing, the test piece 200 is inserted into the clearance hole 11. The clamping assembly fixes the test piece 200 on both sides of the mounting base 1 in the thickness direction, and the fastening part 213 is tightened onto the pin body 211. The electrical connector 31 is adjusted to connect the pin 3122 to the test piece 200. The discharge device 32 is activated and begins to work, consuming the power of the test piece 200. The power display component 4 can display the power of the test piece 200 in real time. When the power of the test piece 200 is consumed to the target value, the pin 3122 in the electrical connector 31 is disconnected from the test piece 200, the test piece 200 is removed, and the discharge test ends.

[0061] The sequence numbers of the embodiments in this application are for descriptive purposes only and do not represent the superiority or inferiority of the embodiments. The above are merely preferred embodiments of this application and do not limit the patent scope of this application. Any equivalent structural or procedural transformations made based on the content of this application's specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this application.
