[0002] Energy has become a highly sought-after treasure in today's rapidly developing society. The positive relationship between energy consumption and economic development has become common sense engraved in everyone's subconscious. However, with the explosive growth of China's economy, energy consumption has become particularly scarce. According to the national budget, within the next 10 years, the growth rate of China's automobiles has exceeded the amount of imported crude oil. If we want to maintain the profit points of the growth of the automobile manufacturing industry, we must innovate in energy. The driving method using gasoline as energy must be reformed to meet the needs of the future market.

[0003] At the current level of world science and technology, the battery is the only driving method that can be widely used and has extremely strong applicability. There have been many successful cases at home and abroad to prove the feasibility of electric vehicles. However, the technical bottleneck for the popularization of electric vehicles is the charging time. The charging time of a dozen or so hours makes electric vehicles only in the hands of urban office workers. Therefore, it can be said that for electric vehicles to achieve further revolutionary development, the electric vehicle battery must be able to achieve a certain degree of breakthrough. In this context, the blade battery has emerged due to its unique charge and discharge performance and service life, and is deeply welcomed by the majority of electric vehicle manufacturers. However, before each battery leaves the factory and is installed in a vehicle, it must first undergo strict performance and safety tests. However, when the existing battery testing machine tests defective and leaking batteries, it is extremely easy to be contaminated by the electromagnetic liquid. At this time, the machine must be stopped for cleaning to avoid accidents. Therefore, the efficiency of the existing battery testing machine is greatly affected by the problem of leaking defective batteries, and there are certain safety hazards.

[0004] It is of great practical significance to design a battery testing machine that can avoid being contaminated by battery liquid. Summary of the Invention

[0005] In order to overcome the deficiencies of the prior art, the purpose of the present invention is to install a liquid receiving tray below the battery contact facing the probe to receive the leaked liquid of defective batteries, so as to achieve the purpose of avoiding contamination of the machine by battery liquid.

[0007] Further, the liquid receiving box has a main body portion and two fixing pieces extending outward from both ends of the main body portion, and two screws respectively pass through the two fixing pieces to fix the liquid receiving box on the vertical surface.

[0008] Further, the two screws on each vertical surface are not located between the two rows of probes.

[0009] Further, the main body portion has a front end face and a rear end face arranged opposite to each other and a bottom surface connecting the front end face and the rear end face, and the front end face and the rear end face are in a T shape.

[0010] Further, the liquid receiving box does not contact the vertical surface.

[0011] Further, the distance from the fixing piece to the front end face is equal to the distance from it to the rear end face.

[0012] Further, a plurality of fans are located above the probes and are arranged in a row.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0026] Next, in combination with the drawings and specific embodiments, the embodiments of the present invention will be further described.

[0027] Such as Figure 1 and Figure 2As shown in the figure, the blade battery testing machine assembly 100 with a liquid receiving box has an external bracket 102 and a plurality of testing machines stacked and fixedly stored in the vertical direction. Each testing machine can test a group of blade batteries 200. With this setting, the blade battery 200 testing assembly with the liquid receiving box 3 can test multiple groups of blade batteries 200 simultaneously within a limited storage space, improving the usage efficiency of the battery 200 testing assembly.

[0028] As Figures 2 to 7 shown in the figure, the blade battery testing machine 101 with a liquid receiving box includes two fixing frames 1, which are fixed to the external bracket 102, and the two fixing frames 1 are arranged opposite to each other left and right. Each fixing frame 1 has a vertical surface 11, and the two vertical surfaces 11 are arranged opposite to each other. A plurality of probes 2 are arranged on the two vertical surfaces 11. There are two rows of the probes 2 on each vertical surface 11, and the number of the probes 2 in each row is equal. In this embodiment, the number of the probes 2 in each row is equal, which enables each probe 2 to make full use of the test at the same time, increasing the usage efficiency of the blade battery testing machine 101 with a liquid receiving box.

[0029] A liquid receiving box 3 is installed on one of the two vertical surfaces 11, and the liquid receiving box 3 is located between the two rows of the probes 2 on this vertical surface 11. Each liquid receiving box 3 has an opening 31, and the opening 31 faces the upper row of the probes 2. When the battery 200 testing machine is in use, a battery 200 is clamped between the two vertical surfaces 11. The two ends of the battery 200 respectively have two contacts, which are electrically connected to the two rows of probes 2 on the two vertical surfaces 11, and the two contacts at the upper ends of the two ends of the battery 200 respectively face the openings 31 of the two liquid receiving boxes 3. With this setting, when the battery 200 leaks liquid due to being unqualified, the battery liquid can flow into the liquid receiving box 3 through the opening 31, preventing the battery liquid from contaminating the probes 2 or other electronic components, resulting in the shutdown or damage of the blade battery testing machine 101 with a liquid receiving box; on the other hand, since the battery liquid is centrally collected in the liquid receiving box 3, it also facilitates the cleaning and wiping of the blade battery testing machine 101 with a liquid receiving box.

[0030] Specifically, the liquid receiving box 3 has a main body portion 32 and two fixing pieces 33 extending outward from both ends of the main body portion 32. Two screws 4 respectively pass through the two fixing pieces 33 to fix the liquid receiving box 3 on the vertical surface 11, thus ensuring the integrity of the cavity of the liquid receiving box 3 and enabling the liquid receiving box 3 to be stably fixed on the fixing frame 1. Further, the two screws 4 on each vertical surface 11 are not located between two rows of the probes 2 to prevent the screws 4 from interfering with the cooperation between the battery 200 and the probes 2; the main body portion 32 has a front end face 321 and a rear end face 322 arranged oppositely and a bottom face 323 connecting the front end face 321 and the rear end face 322, and the front end face 321 and the rear end face 322 are in a T shape, which can ensure that the opening 31 is as large as possible to facilitate containing the leaked battery liquid and can also hide the screws 4 in the liquid receiving box 3. In addition, the liquid receiving box 3 does not contact the vertical surface 11 to prevent the battery liquid in the liquid receiving box 3 from contaminating the vertical surface 11; the distance from the fixing piece 33 to the front end face 321 is equal to the distance from the fixing piece 33 to the rear end face 322, ensuring the structural stability of the entire liquid receiving box 3.

[0031] To facilitate the heat dissipation of the probes 2, a plurality of fans 5 are located above the probes 2 and are arranged in a row. In this embodiment, a more ingenious design is that each vertical surface 11 is provided with a row of the fans 5, and the fans 5 are arranged in an upward inclined manner, which better exerts the heat dissipation efficiency of the fans 5 and ensures the normal operation of the probes 2 and the accuracy of the test. In this embodiment, the blade battery testing machine 101 with a liquid receiving box is a relatively advanced blade battery 200 used in new energy vehicles at present. One battery 200 is respectively connected to only four probes 2, and its four contacts are respectively distributed at both ends of the battery 200, with two contacts at each end, which are respectively electrically connected to one probe 2 in the upper row and one probe 2 in the lower row on two vertical surfaces 11.

[0032] The blade battery testing machine 101 with a liquid receiving box further includes a support assembly 6. The support assembly 6 includes four vertical beams 61, one cross beam 62 and two support beams 63. Opposite ends of the cross beam 62 are mounted on two of the vertical beams 61. One ends of the two cross beams 62 are simultaneously mounted on the cross beam 62, and the other ends are respectively mounted on the other two vertical beams 61. The two vertical planes 11 are located between the two vertical beams 61 that support the cross beam 62, and the two vertical beams 61 that support the two support beams 63 are located between the two vertical planes 11. In this way, it is ensured that the battery 200 can pass through the two vertical beams 61 from one direction, facilitating the installation of the battery 200. A switching plate 8 is mounted on the two support beams 63, and the switching plate 8 slides relative to the support beams 63, and its sliding direction is consistent with the longitudinal length direction of the vertical plane 11. Specifically, a plurality of pulleys 7 are mounted on opposite side surfaces of the two support beams 63. The switching plate 8 includes a support plate 81 and two support blocks 82 mounted on the lower surface of the support plate 81. The two support blocks 82 are U-shaped, and their lower surfaces are respectively supported on two rows of the pulleys 7, so that the switching plate 8 can slide along the pulleys 7 in the length direction of the support blocks 82.

[0033] In addition, two stop pieces 64 are mounted on the surface of the cross beam 62 and are located on opposite sides of the switching plate 8 to stop the left-right and upward displacement of the switching plate 8. Specifically, the stop piece 64 includes a first folding piece 641, a second folding piece 642 extending vertically upward from the first folding piece 641, and a third folding piece 643 extending horizontally from the second folding piece 642. The first folding piece 641 is fixed to the cross beam 62. The second folding piece 642 stops the left or right displacement of the switching plate 8, and the third folding piece 643 is located above the switching plate 8 to stop the upward displacement of the switching plate 8. Positioning pieces 85 extend outward from both side surfaces of the support plate 81. When the switching plate 8 slides completely into place, the two positioning pieces 85 are respectively fixed to the two support beams 63 by two screws.

[0034] A series unit component cover 83 is installed on the upper surface of the switching board 8. A plurality of series unit components 84 are installed on the upper surface of the switching board 8 and are covered within the series unit component cover 83. A plurality of the fans 5 are installed on the upper surface of the series unit component cover 83. When the battery 200 tester is in use, a battery 200 is clamped between two of the vertical surfaces 11. Two contacts are respectively provided at both ends of the battery 200 and are electrically connected to two rows of probes 2 on the two vertical surfaces 11 respectively. The series unit component 84 transmits various performance indicators of the battery 200 to be tested, and dissipates heat through the fan 5. By installing a plurality of the series unit components 84 on the push-pullable switching board 8, it is convenient for the maintenance and repair of the series unit component 84.

[0035] Preferably, a fixing plate 9 is located below the probes 2 in the lower row and is arranged between the two vertical surfaces 11. A plurality of chip components 10 are arranged on the upper surface of the fixing plate 9 and face the battery 200. When the battery 200 tester is in use, a battery 200 is clamped between two of the vertical surfaces 11. Two contacts are respectively provided at both ends of the battery 200 and are electrically connected to two rows of probes 2 on the two vertical surfaces 11 respectively. The chips are located below the battery 200 to scan the flow condition of liquid ions in the battery 200 and calculate the magnetic field intensity distribution condition of the battery 200, thereby judging the liquid injection condition of the battery 200. Further, a plurality of the chips are arranged in an array on the fixing plate 9, and all the chips are located directly below the battery 200 to ensure that the chip component 10 can accurately scan the required magnetic field change information of the battery 200. In addition, the chip includes a signal processor and a magnetic induction sensor. The magnetic field condition inside the electromagnetic is scanned by the magnetic induction sensor and transmitted to the signal processor, and the signal processor converts and calculates the liquid distribution condition inside the battery 200. The distance between the fan 5 and the probes 2 is greater than the distance between the chip component 10 and the probes 2, which better balances the heat dissipation effect and the distance from the battery 200 required for the accuracy of the chip component 10 to scan the magnetic field information.

[0036] In this embodiment, the chip component 10 (TMR chip) uses a magnetic field sensor that adopts the latest magnetic induction scanning technology, which has advantages such as high sensitivity, temperature stability, anti-interference, miniaturization, integration, intelligence, and low power consumption. Specifically, it generates corresponding data according to the magnetic field intensity generated by the flow direction of the two poles of the battery 200 to judge the quality of the liquid uniformity in the battery 200, which is intuitive and concise.

[0037] The above embodiments are only the preferred embodiments of the present invention and cannot be used to limit the scope of protection of the present invention. Any non-substantial changes and substitutions made by those skilled in the art based on the present invention belong to the scope of protection required by the present invention.
