Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.
[0022] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.
[0023] This application discloses the structure of a compatible open-circuit voltage testing device. (Refer to...) Figures 1-4 A structure for a compatible open-circuit voltage testing device includes a testing platform 1. Four support legs 3 are fixedly connected to the bottom of the testing platform 1. Two L-shaped connecting rods 7 are fixedly connected to the top of the testing platform 1. A support plate 18 is fixedly connected to one side of each L-shaped connecting rod 7. A battery voltage detector 10 is fixedly mounted on the top of the support plate 18. Testing pens 16 are electrically connected to both sides of the battery voltage detector 10. First electric telescopic rods 11 are provided on both sides of the support plate 18. A second electric telescopic rod 9 is provided on one side of the battery voltage detector 10. A feeding mechanism 2 is provided at the bottom of the testing platform 1.
[0024] The feeding mechanism 2 includes a base 201, with reinforcing blocks 5 fixedly connected to both sides of the base 201. The opposite sides of the two reinforcing blocks 5 are fixedly connected to the opposite sides of the two support legs 3. A hydraulic cylinder 206 is fixedly installed on the inner wall of the base 201, and a lifting plate 207 is fixedly connected to the telescopic end of the hydraulic cylinder 206.
[0025] Reference Figure 4 The top of the base 201 is fixedly connected to a limiting plate 204. There are two limiting plates 204, and each limiting plate 204 has an installation groove 13 on its inner wall. The inner cavity of the installation groove 13 is rotatably connected to a first roller 205 via bearings. There are several first rollers 205. The inner wall of the base 201 is rotatably connected to a second roller 208 via bearings. There are several second rollers 208. Two fixing plates 203 are fixedly connected to one side of the base 201. A third roller 202 is rotatably connected between opposite sides of plate 203 via bearings. There are several third rollers 202. By setting a limiting plate 204, the mounting groove 13 and the first roller 205 work together to increase the stability and smoothness of the battery when moving, and to prevent the battery from shifting or getting stuck when moving. By setting a second roller 208 and the third roller 202 work together to make the battery move more smoothly and reduce the friction generated when the battery moves.
[0026] Reference Figure 1 , Figure 2 and Figure 3 The inner wall of the testing platform 1 is provided with an auxiliary groove 17, which is used in conjunction with the lifting plate 207. A protective shell 6 is movably connected to the top of the testing platform 1. A protective glass 14 is fixedly installed on one side of the protective shell 6. One side of the protective shell 6 is fixedly connected to the telescopic end of the first electric telescopic rod 11. By setting the auxiliary groove 17, space can be provided for the movement of the lifting plate 207, so that the lifting plate 207 can lift the battery to the testing position. By setting the protective shell 6 and the protective glass 14, the safety of the battery during testing can be increased, and dangerous situations can be avoided during the testing of the battery, thereby increasing the safety of the testing personnel.
[0027] Reference Figure 1 The top of the protective shell 6 has a through slot 12. There are two through slots 12. The through slots 12 are used in conjunction with the test pen 16. By setting the through slots 12, the test pen 16 can pass through the protective shell 6 to test the battery, so as to avoid the protective shell 6 affecting the test pen 16's test of the battery.
[0028] Reference Figure 1 and Figure 2A first mounting block 15 is fixedly connected to the surface of the first electric telescopic pole 11. The side of the first mounting block 15 closest to the support plate 18 is fixedly connected to the support plate 18. By setting the first mounting block 15, the stability and firmness of the first electric telescopic pole 11 during use can be increased, and the first electric telescopic pole 11 can be prevented from moving during use.
[0029] Reference Figure 1 and Figure 2 A second mounting block 8 is fixedly connected to the surface of the second electric telescopic pole 9. The side of the second mounting block 8 closest to the battery voltage detector 10 is fixedly connected to the battery voltage detector 10. By setting the second mounting block 8, the stability and firmness of the second electric telescopic pole 9 during use can be increased, and the movement of the second electric telescopic pole 9 during use can be prevented.
[0030] Reference Figure 1 , Figure 2 and Figure 3 The bottom of the base 201 is fixedly connected with two support blocks 4. By setting the support blocks 4, the stability and firmness of the base 201 during use can be increased, and the base 201 can be prevented from being affected by external forces during use and thus from malfunctioning.
[0031] Working Principle: To test the open-circuit voltage of a battery, the battery is first transported to the base 201 via the third roller 202 and the second roller 208. The testing personnel then move the battery, causing it to contact the first roller 205. Guided by the first roller 205 and the limiting plate 204, the battery enters the lifting plate 207. At this point, the testing personnel activate the hydraulic cylinder 206 via an external power supply and switch. The extension and retraction end of the hydraulic cylinder 206 raises the lifting plate 207, which in turn raises the battery. When the lifting plate 207 reaches the position of the auxiliary slot 17, the battery is in the test position. The testing personnel then connect the external power supply... The second electric telescopic rod 9 is activated by a switch. The telescopic end of the second electric telescopic rod 9 moves the protective shell 6, causing it to descend. Once the protective shell 6 is lowered to a suitable position, it covers the battery, increasing battery safety during testing. Then, the testing personnel simultaneously activate the first electric telescopic rod 11 via an external power supply and switch. The telescopic end of the first electric telescopic rod 11 lowers the testing pen 16, bringing it into contact with the battery terminals. The open-circuit voltage of the battery is then input through the testing pen 16, and read by the battery voltage detector 10, thus completing the open-circuit voltage test of the battery.
[0032] It is worth noting that the battery voltage detector 10 is a device used to measure the battery voltage. It belongs to the category of battery testing instruments. It is responsible for collecting the battery voltage signal. Through two conductive pens, the two conductive pens are connected to the positive and negative terminals of the battery tabs respectively. The collected analog voltage signal is converted into a digital signal by an analog-to-digital converter. The voltage condition is judged by observing the digital signal for subsequent processing.
[0033] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
