[0030] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below in conjunction with the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0031] See Figure 1 This utility model claims protection testing fixture, which is mainly used for testing the charge and discharge of cylindrical batteries, including a base 1, a baffle 2, a first adjusting component, a mounting part, a base support 6, and a second adjusting component.

[0032] The base 1 is equipped with a baffle 2. Specifically, the base 1 has an L-shaped cross-section. A first groove 10 is formed along the length of the horizontal plate of the base 1. The first groove 10 cooperates with a first slider 20 provided at the bottom of the baffle 2. The baffle 2 and the vertical plate of the base 1 are parallel to each other. The first groove 10 is preferably a square groove, and the first slider 20 is a square block adapted to the first groove 10. In actual production, the first groove 10 is not limited to a square groove; it can also be a dovetail groove or a U-shaped groove. However, it is necessary to ensure that the first slider 20 is adapted to the first groove 10.

[0033] The first adjusting component is configured to allow the adjusting baffle 2 to slide along the length of the base 1. Specifically, a first threaded hole 30 is opened on the side of the horizontal plate of the base 1 away from the vertical plate of the base 1. The first threaded hole 30 is connected to the first sliding groove 10. The first bolt 31 passes through the first threaded hole 30 and is rotatably engaged with the bottom side of the baffle 2. The first bolt 31 and the first threaded hole 30 constitute the first adjusting component.

[0034] It is worth noting that a distance needs to be reserved between the two ends of the first slide groove 10 and the horizontal plate of the base 1 to ensure that the first bolt 31 can engage with the horizontal plate of the base 1. Moreover, the axis of the first threaded hole 30 is parallel to the length of the first slide groove 10 to ensure that the adjustment direction of the first bolt 31 is consistent with the sliding direction of the baffle 2.

[0035] At this point, the baffle 2 and the base 1 enclose a space. The U-shaped cross-section of this space allows a cylindrical battery to be placed inside during actual use. Specifically, a base support 6 is provided on the horizontal plate of the base 1, and the top surface of the base support 6 is arc-shaped. The arc-shaped design can fit against the outer wall of the cylindrical battery, thus providing good support for the cylindrical battery even during adjustment.

[0036] Of course, in actual production, the top surface of the base 6 can be arc-shaped, but not limited to V-shaped. This not only makes it suitable for supporting most cylindrical batteries, but also reduces contact with the battery surface, achieving two goals at once.

[0037] An installation part is provided on the outer side of the space. The second adjusting member is configured to adjust the sliding of the installation part along the height direction. Specifically, the second adjusting member includes a second sliding groove, a second screw, and a second nut. The second sliding groove passes through the surface of the longitudinal plate of the base 1 and the surface of the baffle 2. The length of the second sliding groove is parallel to the height direction of the baffle 2. One end of the second screw passes through the second sliding groove to form the inner end of the second screw. The installation part is provided at the inner end of the second screw, and the outer end of the second screw is threadedly engaged with the second nut. Furthermore, a spring can be sleeved on the inner end of the second screw. The spring is preferably made of insulating material.

[0038] The mounting section is used to install the positive and negative probes, which are respectively located on the inner side of the longitudinal plate of base 1 and the inner side of the baffle 2. The second adjusting component on the longitudinal plate of base 1 is defined as the second left adjusting component. The second left adjusting component includes a second left sliding groove 50a, a second left screw 51a and a second left nut 52a. At this time, the longitudinal plate of base 1 passes through the second left sliding groove 50a. One end of the second left screw 51a passes through the second left sliding groove 50a to form the inner end of the second left screw 51a. The positive probe is installed at the inner end of the second left screw 51a. The outer end of the second left screw 51a is threadedly engaged with the second left nut 52a.

[0039] Similarly, the second adjusting component on the vertical plate of the base 1 is defined as the second right adjusting component. The second right adjusting component includes a second right sliding groove 50b, a second right screw 51b, and a second right nut 52b. At this time, the surface of the baffle 2 passes through the second right sliding groove 50b, one end of the second right screw 51b passes through the second right sliding groove 50b to form the inner end of the second right screw 51b, a negative probe is provided at the inner end of the second right screw 51b, and the outer end of the second right screw 51b is threadedly engaged with the second right nut 52b.

[0040] When in use, the second left screw 51a needs to be slid along the second left slide groove 50a until the positive electrode probe is aligned with the positive terminal of the cylindrical battery. The alignment of the negative electrode probe is the same, and will not be described again.

[0041] It is worth noting that both the base 1 and the baffle 2 are made of insulating material, which can effectively prevent current from passing through.

[0042] The process of using this testing fixture for charging and discharging tests of cylindrical batteries is as follows:

[0043] Place the cylindrical battery on the base 6 with the positive terminal facing the positive probe and the negative terminal facing the negative probe.

[0044] Twist the first bolt 31 so that the first bolt 31 engages with the first threaded hole 30, thereby driving the baffle 2 to slide along the first slide groove 10 until the positive electrode probe and the positive electrode of the cylindrical battery are on the same vertical line, and the negative electrode and the negative electrode probe are on the same vertical line.

[0045] Holding the second left screw 51a, slide it within the second left groove 50a. When the positive terminal of the cylindrical battery is aligned with the positive probe, screw the second left nut 52a onto the second left screw 51a. As the second left nut 52a is screwed on, the positive probe at the inner end of the second left screw 51a adheres to the positive terminal of the cylindrical battery, thus securing it. The second right screw 51b is handled similarly, and will not be described further.

[0046] It is worth noting that the adjustment process of the second adjustment component and the first adjustment component is mutually adaptive, and the order of adjustment is not important. The main purpose is to align the positive electrode of the cylindrical battery with the positive electrode probe, and the negative electrode of the cylindrical battery with the negative electrode probe.

[0047] The entire testing process does not require frequent soldering or plugging / unplugging, causing minimal damage to cylindrical batteries and probes. It can also adapt to batteries of different sizes, making it simple, practical, and highly applicable.

[0048] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
