[0050] Embodiment 1

[0051] The embodiment of the present application provides a battery test fixture,Figure 1 is a schematic perspective view of a battery test fixture provided by an embodiment of the present application. As Figure 1 shown, the fixture includes: a fixing frame 1, test probes 2, a probe fixing plate 3, and a fixture assembly 4. The battery under test 5 is placed in the battery accommodation space provided within the fixing frame 1 of the fixture. The fixing frame 1 includes a bottom plate 11, side plates 13 on both sides, and a sliding assembly 16 fixed to the side plates 13.

[0052] In the embodiment of the present application, the fixture is used to stably hold the battery under test and press the test probes against the electrode posts of the battery. Specifically, the probe fixing plate 3 moves with the test probes 2 and applies a pre-tightening force to press against the electrode posts of the battery, facilitating the power-on test.

[0053] In the embodiment of the present application, the bottom plate 11 serves as the base of the fixing frame 1 and combines with the two side plates 13 to form a basic frame for accommodating the battery. In a possible implementation, the fixing frame 1 further includes a rear baffle 15 adapted to support the battery accommodation space and a fixture fixing plate 18 disposed on the same plane as the rear baffle 15. The fixture assembly 4 is then fixed to the fixing frame 1 through the fixture fixing plate 18. The rear baffle 15 is used to reinforce the entire fixing frame 1 and enhance the supporting force of the fixing frame for the clamped battery.

[0054] Optionally, the bottom plate 11, side plates 13, rear baffle 15, and fixture fixing plate 18 in the fixing frame 1 are made of wooden boards of insulating wood material.

[0055] Figure 2 is a schematic perspective view of another battery test fixture provided by an embodiment of the present application. As Figure 2 shown, the fixture includes a fixing frame 1, test probes 2, a probe fixing plate 3, and a fixture assembly 4; the fixing frame 1 further includes a bottom plate 11, side plates 13, a sliding mechanism 16, a rear baffle 15, and a fixture fixing plate 18.

[0056] In the embodiment of the present application, the probe fixing plate 3 serves as a connecting member between the fixture assembly 4 and the test probes 2, and can transmit the pushing and pulling force on the fixture assembly 4 to the pushing and pulling force on the test probes 2.

[0057] Among them, the test probes 2 are fixed on the first side of the probe fixing plate 3; the movable end of the fixture assembly 4 is connected to the second side of the probe fixing plate 3. Exemplarily, when the fixture is placed vertically, with the bottom plate 11 on the ground and the side plates 13 perpendicular to the ground, the probe fixing plate 3 is placed parallel to the bottom plate 11 between the two side plates 13. The first side of the probe fixing plate 3 refers to the lower side, and the second side refers to the upper side. Specifically, for a probe fixing plate 3 placed horizontally parallel to the ground, the test probes 2 are fixed on its lower side, and the movable end of the fixture assembly 4 is fixed on its upper side.

[0058] Among them, both ends of the probe fixing plate 3 are respectively connected to the sliding components 16 on the two side plates 13. The sliding components 16 in this fixture are used to ensure stable support and guidance during the up-and-down pushing and pulling process, preventing the probe fixing plate 3 and the test probe 2 from shifting or shaking during the up-and-down movement.

[0059] In the embodiment of the present application, during the pushing and pulling process of the fixture assembly 4, the fixture assembly 4 is affected by the thrust or pull from the operator, as well as loads such as its own gravity. The sliding components 16 are used to bear these loads and transfer them to the fixed part (fixed frame 1) of the fixture or the foundation, ensuring that the fixture can still maintain stable performance when bearing the loads.

[0060] Among them, by pushing and pulling the movable end of the fixture assembly 4, the probe fixing plate 3 slides relative to the bottom plate 11 along the two sliding components 16 on both sides, driving the test probe 2 installed on the probe fixing plate 3 to press against or disengage from the electrode posts of the battery placed on the bottom plate 11.

[0061] Based on this, when the movable end of the fixture assembly 4 is pushed and pulled up and down, it will synchronously drive the probe fixing plate 3 to slide up and down, so as to synchronously drive the test probe 2 on the lower side to press and disengage.

[0062] It should be noted that the so-called electrode posts of the battery in the present application actually refer to the cell electrode posts of the cell inside the battery. The cell electrode posts are components of the cell, which are directly connected to the positive and negative electrodes of the cell and connect the cell to the external circuit. In some embodiments, the cell part of the battery can also be directly clamped and detected, that is, the battery 5 can be replaced by a certain cell to be tested.

[0063] The present application proposes a battery test fixture with a compact overall structure, which uses a probe fixing plate to connect the push-pull type fixture assembly and the test probe, uses a sliding component to realize the up-and-down sliding of the probe, and uses a push-pull type fixture to easily push and pull to tighten and loosen the battery. Through the push-pull pre-tightening method, the test stability and work efficiency are improved, the safety hazard of debris caused by frequent screwing is avoided, and the test efficiency is effectively improved.

[0064] Embodiment 2

On the plate body 34 of the probe fixing plate 3, there are provided sliding bushings 31, probe holes 32, and fixture holes 33.

[0066] In the embodiment of the present application, the sliding structure 16 includes a sliding rod. The sliding rod can be a sliding rod without threads on its surface, or a sliding lead screw. Specifically, a sliding rod without threads is suitable for simple linear motion and situations with relatively small loads. The sliding lead screw realizes the conversion from rotational motion to linear motion through the convex lead screw inside it and the mating thread bushing. When the lead screw rotates, the mating thread bushing will generate a linear displacement, thereby realizing the up and down pushing and pulling actions of the fixture. Compared with other sliding rods, using a sliding lead screw can ensure that the fixture has a stable motion trajectory during the pushing and pulling process, without lateral deviation, enabling the test probe to press more accurately onto the position where the electrode post is located.

[0067] In the embodiment of the present application, the fixing member 17 is used to fix both ends of the sliding rod to the side plates 13. The fixing member 13 is, for example, an element such as a screw nut, a buckle, a hook, a T-shaped fixing member, or a right-angle fixing member that can fix both ends of a straight rod to a wooden board.

[0068] In the embodiment of the present application, a plurality of holes are provided on the probe fixing plate 3 for fixing corresponding components on both sides. Specifically, the provided holes include: probe holes 32 and fixture holes 33.

Exemplarily, the battery test fixture is placed vertically, with the bottom plate 11 on the ground and the side plates 13 perpendicular to the ground. Then the probe fixing plate 3 is placed parallel to the bottom plate 11 between the two side plates 13. The first side of the probe fixing plate 3 refers to the lower side, and the second side refers to the upper side.

[0070] In the embodiment of the present application, each sliding rod passes through the probe hole 32 on its own side and is sleeved within the corresponding sliding bushing 31 on that side. The sliding bushings 31 on both sides of the probe fixing plate 3 move on the sliding lead screw fixed on the side, overall improving the smoothness and stability of the movement of the test probe 2. Specifically, the sliding bushing 31 and the sliding lead screw are coaxially installed.

[0071] Optionally, the sliding bushing 31 is welded to both sides of the probe fixing plate 3 to facilitate the reciprocating movement of the sliding lead screw.

[0072] Optionally, at least one end of the sliding rod is sleeved with an elastic buffer kit, and the elastic buffer kit is adapted to reduce the acting force on the fixing member 17 during the up and down sliding of the probe fixing plate 3 along the sliding rod. The elastic buffer kit can be, for example, a spring kit, a damping kit, a rubber or polyurethane buffer kit, etc., and the present application is not limited thereto.

[0073] In the embodiment of the present application, the fixture assembly 4 is fixed to the fixing frame 1 through the fixture fixing plate 18, and the movable end of the fixture assembly 4 is fixed through the fixture hole 33 provided in the middle of the probe fixing plate 3.

[0074] In the embodiment of the present application, the test probe 2 includes: a probe bushing 21, a probe fixing member 22, and a probe head 23.

[0075] Wherein, the probe head 23 is adapted to contact the electrode post on the first side. The probe fixing member 22 is adapted to lock the test probe 2 to the first side of the probe fixing plate 3. The probe bushing 21 is adapted to cooperate with the probe fixing member 22 on the second side of the probe fixing plate 3 to fix the test probe 2 in the probe hole 32. Specifically, the probe head 23 can be locked to the probe fixing plate 3 through the probe fixing member 22 by using screws, and fixed with the probe bushing 21 on the other side.

[0076] Figure 4 is a schematic diagram of installing a probe provided by the embodiment of the present application, as Figure 4 shown, a fixture hole 33 is provided at the center of the probe fixing plate 3, and a pair of probe holes 32 are symmetrically arranged on both sides with the fixture hole as the center; sliding bushings 31 are provided on both sides of the probe fixing plate 3 where the sliding lead screw is installed; the test probe 2 includes several parts such as a probe head 23, a probe fixing member 22, and a probe bushing 21.

[0077] In the embodiment of the present application, the fixture assembly 4 includes: a clamping device and a movable end, and the clamping device is adapted to clamp the movable end and push and pull the movable end in a direction perpendicular to the plane where the bottom plate 11 is located. Exemplarily, the movable end is a connecting rod, one end of the connecting rod can be fixed to the clamping device by means of bolts, pins, welding, etc., and the other end can be fixed to the probe fixing plate 18 by means of mortise and tenon, screws, press-fitting, etc. Optionally, the clamping device is provided with a wrench, and the probe fixing plate can be quickly pushed up and down by pushing and pulling the wrench.

[0078] In a possible implementation manner, the clamping device can also be replaced with other push-pull type fixtures that can achieve quick push-pull operations.

[0079] In the embodiment of the present application, the process of pressing the battery cell by the fixture assembly 4 in the battery test fixture includes: when the tensioning clamp is tightened, the probe fixing plate 3 is pushed by the movable end along the sliding assemblies 16 on both sides towards the direction close to the bottom plate 11, so that the test probes 2 installed on the probe fixing plate 3 press the electrode posts of the battery placed on the bottom plate 11.

[0080] In the embodiment of the present application, the process of loosening the battery cell by the fixture assembly 4 in the battery test fixture includes: when the tensioning clamp is loosened, the probe fixing plate 3 is pulled by the movable end along the sliding assemblies 16 on both sides towards the direction away from the bottom plate 11, so that the test probes 2 installed on the probe fixing plate 3 are separated from the electrode posts of the battery placed on the bottom plate 11.

[0081] In the embodiment of the present application, the lower stop bar 12 of the fixing frame 1 is arranged between the two side plates 13 on the upper side of the bottom plate 11. The lower stop bar 12 is suitable for supporting and strengthening the battery accommodation space in the fixing frame 1.

[0082] In the embodiment of the present application, at least two guide bars 14 of the fixing frame 1 are symmetrically fixed to the two side plates 11 respectively. The at least two guide bars 14 are suitable for strengthening the battery accommodation space and guiding the placement direction of the battery. Optionally, 2 guide bars 14 are provided on each of the left and right sides.

[0083] The lower stop bar and the rear baffle can facilitate the positioning of the battery cell, and two guide bars on each side can meet the guiding and positioning requirements on the left and right sides of the battery cell.

[0084] In a possible implementation manner, the edge of the lower stop bar 12 in contact with the battery is processed into an inclined surface that inclines at a first preset angle relative to the horizontal plane towards the inside of the fixing frame 1; the edge of any guide bar 14 in contact with the battery is processed into an inclined surface that inclines at a second preset angle towards the inside of the fixing frame 1; based on this, when the battery contacts the edge of the lower stop bar 12, the battery inclines towards the inside of the fixing frame under the action of gravity, and falls into the battery accommodation space in the fixing frame 1 under the guidance of the direction of the guide bar 14.

[0085] Figure 5 is a top view of a battery test fixture provided by an embodiment of the present application, as Figure 5 shown, the bottom plate 11 included in the fixing frame 1 is provided with a lower stop bar 12, guide bars 14 are provided on both sides of the side plate 13, the contact surface of the guide bar 14 facing outwards is cut into an inclined surface, and the contact surface of the lower stop bar 12 facing upwards is also cut into an inclined surface.

[0086] Optionally, the height of the lower stop bar is designed to be 1 cm - 2 cm. Based on this, during the process of placing the battery cell, only need to tilt and lift it moderately, and then gently push it to accurately place the battery cell to the specified position in cooperation with the guide bar 14.

[0087] Figure 6 It is a schematic diagram of the alignment of an electric core provided by an embodiment of the present application. As Figure 6 shown, Figure 6 In part (a), it shows the state where the electric core 5 is placed in the battery test fixture at a certain angle. The lower stop bar on the bottom plate and the guiding bars on both sides can play a role to align the electric core. Figure 6 In part (b), it shows the state where the placement of the electric core is completed. At this time, by pulling the fixture assembly 4, the probe fixing plate 3 slides downward through the sliding assembly 2, which can drive the test probe 2 to press downward against the electric core 5, so that the probe head 23 contacts and presses against the electrode post 51 of the electric core 5, and the clamping of the electric core to be tested can be completed.

[0088] By chamfering the lower stop bar and the guiding bars, the efficiency of the alignment of the electric core can be improved, making the use of the fixture more labor-saving and further enhancing the operation convenience.

[0089] Among them, the rear baffle 15 of the fixing frame 1 is suitable for supporting the battery accommodation space. The bottom plate 11, the side plates 13, the rear baffle 15 and the fixture fixing plate 18 constitute the overall frame part of the fixing frame 1. Optionally, according to the size of the battery / electric core to be tested, the size and combination mode of the bottom plate 11, the side plates 13, the rear baffle 15 and the fixture fixing plate 18 can be adjusted to adjust the size of the battery accommodation space of the entire fixture.
