Technical Field

[0001] The invention relates to the field of electric vehicle battery testers, and in particular to a blade battery tester of a push-pull switch plate and a battery tester assembly. Background Art

[0002] Energy has become a treasure that is sought after in today's fast-developing society. The proportional relationship between energy consumption and economic development has become a common sense engraved into everyone's subconscious. However, energy consumption has become even more precious with the explosive growth of my country's economy. According to the national budget, in the next 10 years, the growth rate of my country's automobiles has exceeded the amount of imported crude oil. If you want to maintain the profit point of the growth of the automobile manufacturing industry, you must innovate in energy, and the gasoline-based driving method must be reformed to adapt to the needs of the future market.

[0003] At the current level of science and technology in the world, batteries are the only driving method that can be widely used and has 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 more than ten hours makes electric vehicles only stay in the hands of urban office workers. Therefore, it can be said that if electric vehicles want to develop further revolutionary, electric vehicle batteries must be able to achieve a certain degree of breakthrough. In this environment, blade batteries came into being due to their unique charging and discharging performance and service life, and are deeply welcomed by the majority of electric vehicle manufacturers. However, each battery must undergo strict performance and safety tests before it leaves the factory and is installed on the vehicle. However, the series unit components of the existing battery tester that transmit signals are fixed in the bracket of the tester, making maintenance or replacement extremely inconvenient.

[0004] It is very meaningful to design a battery testing machine which is easy to maintain and overhaul. Summary of the invention

[0005] In order to overcome the deficiencies of the prior art, the present invention aims to facilitate the maintenance and repair of the machine by installing the series unit assembly on a push-pull switch plate.

[0006] The present invention is implemented by the following technical solutions: A blade battery testing machine for push-pull switching plates, comprising: two fixed frames arranged opposite to each other left and right, each of the fixed frames having a vertical surface, and the two vertical surfaces are arranged opposite to each other; a plurality of probes are arranged on the two vertical surfaces, two rows of probes are arranged on each vertical surface, and the number of probes in each row is equal; two support beams are located above the two fixed frames, and the horizontal projections of the two support beams are located between the horizontal projections of the two fixed frames; a switching plate is installed on the two support beams, and the switching plate slides relative to the support beams, and its sliding direction is consistent with the longitudinal length direction of the vertical surface; a plurality of series unit components and a plurality of fans located above the series unit components, and the plurality of series unit components and the plurality of fans are fixed on the switching plate and slide together with the switching plate; when the battery testing machine is in use, a battery is clamped between the two vertical surfaces, and the two ends of the battery respectively have two contacts, which are electrically connected to the two rows of probes on the two vertical surfaces respectively, and the series unit components transmit various performance indicators of the battery to be tested, and it is cooled by the fans.

[0007] Further, a plurality of pulleys are installed on the opposite side surfaces of the two support beams, and the switching plate is supported on the pulleys.

[0008] Further, the switching plate includes a support plate and two support blocks installed on the lower surface of the support plate. The support plate supports the series unit components and the fans. The two support blocks are U-shaped, and their lower surfaces are respectively supported on two rows of pulleys.

[0009] Further, positioning pieces are respectively extended outward from the two side surfaces of the support plate. When the switching plate slides completely into place, the two positioning pieces are respectively fixed to the two support beams by two screws.

[0010] Further, the switching plate is installed on a support assembly. The support assembly includes four vertical beams, a cross beam and two support beams. The opposite ends of the cross beam are installed on the two vertical beams, and one ends of the two cross beams are installed on the cross beam at the same time, and the other ends are respectively installed on the other two vertical beams.

[0011] Further, two stop pieces are installed on the surface of the cross beam and are located on the opposite sides of the switching plate to stop the left-right and upward displacement of the switching plate.

[0012] Further, the stop piece includes a first folding piece, a second folding piece vertically extending upward from the first folding piece, and a third folding piece horizontally extending from the second folding piece. The first folding piece is fixed to the cross beam, the second folding piece stops the switching plate from moving left or right, and the third folding piece is located above the switching plate to stop the switching plate from moving upward.

[0013] Further, the two vertical surfaces are located between two vertical beams supporting the cross beam, and the two vertical beams supporting the two support beams are located between the two vertical surfaces.

[0014] Further, a series unit component cover is installed on the upper surface of the switching plate, covering a plurality of the series unit components, and a plurality of the fans are installed on the upper surface of the series unit component cover.

Detailed implementation manner

[0027] Next, in combination with the accompanying drawings and the detailed implementation manner, the embodiments of the present invention will be further described.

[0028] As Figure 1 and 2 shown, the blade battery testing machine assembly 100 of the push-pull switching board of the present invention 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 such a setting, the blade battery 200 testing assembly with the liquid receiving box 3 can test multiple groups of blade batteries 200 simultaneously in a limited storage space, improving the use efficiency of the battery 200 testing assembly.

[0029] As Figures 2 to 7 shown, the blade battery testing machine 101 of the push-pull switching board includes two fixing frames 1 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. Two rows of the probes 2 are provided 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, so that each probe 2 can make full use of the test at the same time, increasing the use efficiency of the blade battery testing machine 101 of the push-pull switching board.

[0030] A liquid receiving box 3 is installed on one of the two vertical surfaces 11, and the liquid receiving box 3 is located between two rows of the probes 2 on the 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 tester is in use, a battery 200 is clamped between the two 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. The two contacts at the upper ends of both ends of the battery 200 respectively face the openings 31 of the two liquid receiving boxes 3. With such a setting, when the battery 200 is unqualified and leaks liquid, 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 and causing the blade battery tester 101 of the push-pull switching board to stop or be damaged. 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 tester 101 of the push-pull switching board.

[0031] 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 the 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.

[0032] To facilitate the heat dissipation of the probe 2, a plurality of fans 5 are located above the probe 2 and arranged in a row. In this embodiment, a more ingenious design is that each of the vertical surfaces 11 is provided with a row of the fans 5, and the fans 5 are inclined upward, which better exerts the heat dissipation efficiency of the fans 5 and ensures the normal operation of the probe 2 and the accuracy of the test. In this embodiment, the blade battery testing machine 101 of the push-pull switching board 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.

[0033] The blade battery testing machine 101 of the push-pull switching board further includes a support assembly 6. The support assembly 6 includes four vertical beams 61, one cross beam 62 and two support beams 63. The opposite ends of the cross beam 62 are installed on two of the vertical beams 61. One ends of the two cross beams 62 are simultaneously installed on the cross beam 62, and the other ends are respectively installed on the other two vertical beams 61. The two vertical surfaces 11 are located between the two vertical beams 61 supporting the cross beam 62, and the two vertical beams 61 supporting the two support beams 63 are located between the two vertical surfaces 11, so as to ensure that the battery 200 can pass through the two vertical beams 61 from one direction, facilitating the installation of the battery 200. A switching board 8 is installed on the two support beams 63, and the switching board 8 slides relative to the support beams 63, and its sliding direction is consistent with the longitudinal length direction of the vertical surface 11. Specifically, a plurality of pulleys 7 are installed on the opposite side surfaces of the two support beams 63. The switching board 8 includes a support plate 81 and two support blocks 82 installed on the lower surface of the support plate 81. The two support blocks 82 are in a U shape, and their lower surfaces are respectively supported on two rows of the pulleys 7, so that the switching board 8 can slide along the pulleys 7 in the length direction of the support blocks 82.

[0034] In addition, two stop pieces 64 are installed on the surface of the cross beam 62 and located on the 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 vertically extending upward from the first folding piece 641, and a third folding piece 643 horizontally extending 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 - 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 the two 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.

[0035] A series unit component cover 83 is installed on the upper surface of the switching plate 8, and a plurality of series unit components 84 are installed on the upper surface of the switching plate 8 and 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 the two 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. 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 plate 8, it is convenient for the inspection and maintenance of the series unit components 84.

[0036] Preferably, a fixing plate 9 is located below the probes 2 in the lower row and is disposed between the two vertical surfaces 11; a plurality of chip components 10 are disposed on the upper surface of the fixing plate 9, facing the battery 200. When the battery 200 tester is in use, a battery 200 is clamped between the two 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. The chips are located below the battery 200 to scan the flow condition of liquid ions in the battery 200, calculate the magnetic field intensity distribution condition of the battery 200, and further judge the liquid injection condition of the battery 200. Further, the plurality of 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 probe 2 is greater than the distance between the chip component 10 and the probe 2, so as to better balance 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.

[0037] In this embodiment, the chip component 10 (TMR chip) uses a magnetic field sensor that adopts the latest magnetic induction scanning technology, and 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 simple.

[0038] 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.
