Embodiment approach 1

[0021] This embodiment provides a lead-carbon battery oil-resistant plastic casing strength detection device and its detection method, such as figure 1 As shown, the detection device is mainly composed of a base 1, two compression rods 2 and two tension rods 3, the base 1 is opened above, and the left and right sides are two detection side walls 101 oppositely arranged, and the two detection side walls 101 are parallel to each other and are perpendicular to the bottom surface of the base 1, the difference between the distance w1 between the two detection side walls 101 and the width w2 of the plastic case 8 of the battery to be tested is greater than 10 mm; The lower part of each detection side wall 101 symmetrically penetrates through the detection side wall 101 and is located inside the base 1, and the two compression rods 2 are respectively screwed to the two detection side walls 101. In practical applications, the compression rods 2 are usually screw rods. The compression ...

Embodiment approach 2

[0032] This embodiment is a further improvement of Embodiment 1. The main improvement is that in Embodiment 1, the tension block 5 is fixed on the tension end of the tension rod 3. When the plastic case 8 of the battery to be tested is placed on the base 1, since the tension block 5 cannot rotate, it is not easy to just place the two opposite side walls 801 of the plastic case 8 of the battery to be tested between the compression end of the corresponding compression rod 2 and the tension block 5 . However, in this embodiment, the tension block 5 is arranged to be rotatably connected with the tightening end of the tension rod 3, so that when the plastic case 8 of the battery to be tested is placed in the base 1, it is convenient to rotate the tension block 5 Place the two opposite side walls 801 of the plastic case 8 of the battery to be tested between the pressing end of the corresponding pressing rod 2 and the tension block 5 .

[0033] Apart from this, this embodiment is compl...

Embodiment approach 3

[0035] This embodiment is a further improvement of Embodiment 1. The main improvement is that in Embodiment 1, since the tension rod 3 is a screw rod, the two tension rods 3 are screwed to the two detection side walls 101, so that The detection device can only be used for one size of the plastic battery case 8 to be tested. When the size of the plastic case 8 of the battery to be tested becomes smaller or larger, a detection device matching the size needs to be replaced, and the detection cost is relatively high. However, the detection device in this embodiment can be adapted to detect the strength and oil resistance of the plastic case 8 of the battery to be tested in different sizes.

[0036] Specifically, in the lead-carbon battery oil-resistant plastic casing strength detection device in this embodiment, a long strip-shaped through-hole structure adjustment groove 102 is also provided on the two detection side walls 101, such as image 3 , the two adjustment grooves 102 ar...

Abstract

The invention relates to the field of storage battery plastic shell detection and discloses a lead carbon battery oil-resistant plastic shell strength detecting device and method. Pressing ends of twopressing rods (2) symmetrically pass through lower parts of two opposite detection side walls (101) of a base (1) and extend into the base, an adjustment end is located outside the base, the adjustment ends of the two pressing rods are respectively and fixedly provided with two pressing adjustment handles (4), the two pressing rods are respectively connected to two detection sides through threads, tensioning ends of two tensioning rods (3) symmetrically pass through the upper parts of the two detection sides and extend into the base, an adjustment end is located outside the base, the tensioning ends of the two tensioning rods are respectively provided with two tensioning blocks (5) and the adjustment ends of the two tensioning rods are respectively and fixedly provided with two tension adjusting handles (9). The device can simply measure the strength of a battery plastic shell to be detected and ensure the accuracy of the detection.

Description

technical field [0001] The invention relates to the field of testing battery plastic cases, in particular to a strength testing device and a testing method for an oil-resistant plastic case of a lead-carbon battery. Background technique [0002] The battery is an important part of the electric vehicle, but the assembly process of the electric vehicle manufacturer often causes the plastic case of the battery to break. Commonly, the overpressure of the fasteners causes damage to the plastic case, or the contact with oily solvents, such as brake fluid, easily causes the plastic case to break. rupture. Therefore, plastic case manufacturers optimize and upgrade the material properties to improve the strength and oil resistance of the plastic case, and the probability of the plastic case breaking during use of the upgraded plastic case is greatly reduced. Due to changes in the strength and oil resistance of the upgraded shell, conventional sampling testing standards and methods c...
