Description

Technical Field

[0001] The utility model relates to the technical field of battery testing, in particular to a solid-state battery testing mold. Background Art

[0002] Solid-state batteries are a type of battery technology. Unlike lithium-ion batteries and lithium-ion polymer batteries commonly used today, solid-state batteries are batteries that use solid electrodes and solid electrolytes. Since the scientific community believes that lithium-ion batteries have reached their limits, solid-state batteries have been seen in recent years as batteries that can inherit the status of lithium-ion batteries. Solid-state lithium battery technology uses glass compounds made of lithium and sodium as conductive materials to replace the electrolyte of previous lithium batteries, greatly improving the energy density of lithium batteries. The current solid-state battery pressure testing system simulates the structure and working principle of solid-state batteries, tests and studies the electrochemical performance of solid-state batteries with different electrolyte materials under different initial pressures, and records the pressure changes of the battery during the charging and discharging process in real time. The solid-state battery test mold is a mold dedicated to this system, which can simulate soft-pack batteries to test the performance of solid-state batteries before assembling soft-pack batteries.

[0003] A solid-state battery test mold (publication number: CN219456429U) is disclosed in a reference patent. Through the cooperation between the sliding push plate, the driving hinge groove, the upper driving rod, the lower driving rod and the driving mechanism, solid-state batteries of different sizes and the insulating battery sleeve can be limited in the center of the bottom plate. However, it drives two groups of driving rods and the sliding push plate to move through a single driving structure. It is easy for one group of moving push plates to clamp the battery, but the other group has not yet contacted the battery. If the driving mechanism continues to be driven to clamp the battery by the group that has not yet contacted the battery, the clamped group of moving push plates will continue to exert pressure on the battery, resulting in battery damage or equipment damage, affecting the use of the equipment.

[0004] Therefore, a solid-state battery test mold is proposed to solve the above-mentioned problems. Utility Model Content

[0011] The utility model has the following advantages: the utility model can effectively control multiple clamping mechanisms separately through the setting of multi-driving structures, thereby effectively avoiding the situation that traditional equipment drives two groups of driving rods and sliding push plates to move through a single driving structure, which may easily lead to one group of moving push plates having clamped the battery, but the other group has not yet contacted the battery. If the driving mechanism continues to be driven to clamp the battery by the group that has not yet contacted the battery, the clamped group of moving push plates will continue to exert pressure on the battery, thereby causing battery damage or equipment damage, affecting the use effect of the equipment. At the same time, by setting a protective pad and a buffer mechanism, it can effectively avoid the situation that rigid contact occurs between the clamping plate and the pressure plate and the battery, effectively avoid the situation that the battery is damaged and affects the test results, and effectively ensure the use effect of the equipment.

[0016] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0017] The utility model will be further described below in conjunction with the accompanying drawings.

[0018] Example

[0019] Please refer to Figure 1-3 The utility model discloses a solid-state battery testing mold, comprising a testing platform 1 and a placing frame 2. Both sides of the top of the testing platform 1 are fixedly connected with vertical plates 3, and a horizontal plate 4 is slidably connected between the two vertical plates 3. Both sides of the bottom of the horizontal plate 4 are slidably connected with an upper clamping plate 5. The middle part of the bottom of the horizontal plate 4 is fixedly connected with a mounting rod 6, and a buffer rod 7 is slidably connected to the bottom of the mounting rod 6. A pressing plate 8 is fixedly connected to the bottom of the buffer rod 7. The middle part of both sides of the testing platform 1 is slidably connected with a lower clamping plate 9. Through the separate structure setting, the upper clamping plate 5 and the lower clamping plate 9 can be effectively clamped and limited to the battery, effectively avoiding the traditional one driving structure driving two groups of driving rods and sliding push plates to move, which is easy to cause one group of mobile push plates to clamp the battery, but the other group has not yet contacted the battery. If the driving mechanism is continued to be driven to make the group that has not yet contacted the battery clamp the battery, the clamped group of mobile push plates will continue to apply pressure to the battery, thereby causing battery damage or equipment damage, affecting the use effect of the equipment.

[0020] Among them, each vertical plate 3 is fixedly connected to a driving motor 11 at the bottom of the inner wall, and each driving motor 11 output end is fixedly connected to a No. 1 screw 12, and the top of each No. 1 screw 12 is rotatably connected to the top of the inner wall of the corresponding vertical plate 3, and the middle of each No. 1 screw 12 is threadedly connected to a No. 1 slider 13, and the two No. 1 sliders 13 pass through the corresponding vertical plate 3 side wall slide grooves and are fixedly connected to the end of the cross plate 4. The driving motor 11 drives the No. 1 screw 12 to rotate, so that the No. 1 slider 13 drives the cross plate 4 and the mounting parts thereon to move downward, thereby causing the pressure plate 8 to press the battery, and at the same time, the upper clamping plate 5 is moved to a suitable height to clamp the battery.

[0021] Among them, a protective pad 10 is provided on one side of the two upper clamps 5 and the lower clamps 9 close to each other, and each protective pad 10 is fixedly connected to the corresponding upper clamp 5 and the lower clamp 9. The protective pad 10 effectively provides protection when the upper clamp 5 and the lower clamp 9 clamp the battery, avoiding rigid contact between the upper clamp 5 and the lower clamp 9 and the battery.

[0022] Among them, a double-headed motor No. 1 is fixedly connected to the middle of the inner wall of the horizontal plate 4, and a No. 2 screw 15 is fixedly connected to both ends of the No. 1 double-headed motor 14. A No. 2 slider 16 is threadedly connected to the middle of each No. 2 screw 15. The bottom end of each No. 2 slider 16 passes through the bottom slide groove of the horizontal plate 4 and is fixedly connected to the corresponding upper clamping plate 5. Starting the No. 1 double-headed motor 14 drives the two No. 2 screws 15 to rotate, and then the two No. 2 sliders 16 drive the corresponding upper clamping plate 5 to move.

[0023] Among them, the top end of the buffer rod 7 passes through the mounting rod 6 and is fixedly connected with a transmission plate 20. The transmission plate 20 is slidably connected to the inner wall of the mounting rod 6. The top of the transmission plate 20 is fixedly connected with a spring 21. The top of the spring 21 is fixedly connected to the top of the inner wall of the mounting rod 6. Through the buffering of the transmission plate 20 and the spring 21, the rigid contact between the pressure plate 8 and the battery is effectively avoided, ensuring the softness of the contact, avoiding damage to the battery and affecting the test results.

[0024] Among them, a No. 2 double-headed motor 17 is fixedly connected to the middle part of the inner wall of the testing table 1, and a No. 3 screw 18 is fixedly connected to both ends of the No. 2 double-headed motor 17. A No. 3 slider 19 is threadedly connected to the middle part of each No. 3 screw 18. The top of each No. 3 slider 19 passes through the upper slide groove of the testing table 1 and is fixedly connected to the bottom of the corresponding lower clamping plate 9. By starting the No. 2 double-headed motor 17, the two No. 3 screws 18 are driven to rotate, and then the two No. 3 sliders 19 drive the corresponding lower clamping plate 9 to clamp the battery.

[0025] Specifically, when the utility model is used, the battery is placed on the placement rack 2, and then the No. 2 double-headed motor 17 is started to drive the two No. 3 screws 18 to rotate, so that the two No. 3 sliders 19 drive the corresponding lower clamping plate 9 to clamp the battery, and the driving motor 11 is started to drive the No. 1 screw 12 to rotate, so that the No. 1 slider 13 drives the cross plate 4 and the mounting parts thereon to move downward, so that the pressing plate 8 presses the battery tightly, and the rigid contact between the pressing plate 8 and the battery is effectively avoided through the buffering of the transmission plate 20 and the spring 21, ensuring the soft contact, avoiding damage to the battery and affecting the test results, and starting the No. 1 screw 12 to rotate. The double-headed motor 14 drives the two No. 2 screws 15 to rotate, and then the two No. 2 sliders 16 drive the corresponding upper clamping plates 5 to move to clamp the battery, effectively avoiding the traditional situation where one driving structure drives two groups of driving rods and sliding push plates to move, which may easily lead to one group of moving push plates having clamped the battery, but the other group has not yet contacted the battery. If the driving mechanism continues to be driven to clamp the battery by the group that has not yet contacted the battery, the clamped group of moving push plates will continue to exert pressure on the battery, resulting in battery damage or equipment damage, affecting the use of the equipment.

[0026] The above are only preferred implementations of the present invention. It should be pointed out that, for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
