[0027] In order to make the purpose, technical scheme and advantages of the present application more clear, the technical scheme of the present application will be described clearly and completely in combination with the drawings in the present application. Obviously, the described embodiments are some embodiments of the present application, not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor are within the scope of protection of the present application.

[0028] The present application provides a battery plug-in testing device, which will be described below in combination with Figures 1-5 The present application provides a battery plug-in testing device, which will be described below in combination with

[0029] The two limiting plates 100 are symmetrically arranged, and each limiting plate 100 is provided with a rotating shaft limiting hole 101 at its upper and lower ends. The battery plug-in mechanism 200 is arranged between the two limiting plates 100 and is movably connected with the rotating shaft limiting holes 101. The two regulating screws 300 are arranged to threadedly penetrate the two limiting plates 100, and the regulating screws 300 are located between the upper and lower rotating shaft limiting holes 101.

[0030] The battery plug-in mechanism 200 comprises a fixed block 201, a first connecting column 202, a first rotating shaft 203, a second rotating shaft 204, a second connecting column 205, and a suction cup 206. The first end of the first connecting column 202 is connected with the fixed block 201, and the second end is connected with the first rotating shaft 203. The two ends of the first rotating shaft 203 are respectively located in the two upper rotating shaft limiting holes 101. The first end of the second connecting column 205 is connected with the second rotating shaft 204, and the second end is connected with the suction cup 206. The two ends of the second rotating shaft 204 are respectively located in the two lower rotating shaft limiting holes 101.

[0031] As shown in Figure 2 , the cross section of the first rotating shaft 203 is circular, and the diameter of the first rotating shaft 203 gradually increases from its two ends to the middle part. The diameter of the two ends of the first rotating shaft 203 is smaller than that of the rotating shaft limiting hole 101, and the diameter of the middle part is larger than that of the rotating shaft limiting hole 101.

[0032] Further, the structure of the second rotating shaft 204 is consistent with that of the first rotating shaft 203.

[0033] Further, the first end of the first connecting column 202 is connected with the fixed block 201, the second end of the first connecting column 202 is connected with the first rotating shaft 203, and the first end of the second connecting column 205 is connected with the second rotating shaft 204 by metal welding. The suction cup 206 is a perforated suction cup, which is provided with perforations at the bottom and is adsorbed on the tail of the battery 500. The suction cup 206 is fixed by the adhesive tape 400 to prevent the suction cup 206 from being accidentally separated from the battery 500.

[0034] In this embodiment, as shown in Figure 3 , the second end of the second connecting column 205 is provided with a thread, and the second end of the second connecting column 205 extends into the suction cup 206 through the perforations of the suction cup 206. The connecting column located on both sides of the perforations is threadedly connected with a nut 207, and the diameter of the nut 207 is larger than that of the perforation to fix the suction cup 206 on the second connecting column 205. The rubber pad 208 is arranged between the nut 207 outside the suction cup 206 and the suction cup 206, and is sleeved on the second connecting column 205. The rubber pad 208 is soft and elastic, which can effectively buffer and disperse the pressure or impact force from the outside, and is conducive to preventing the external air from entering the inside of the suction cup 206 through the gap, thereby reducing the adsorption force of the suction cup 206.

[0035] When the battery plug test device is not started, under the restriction of the limiting plate 100 and the shaft limiting hole 101, the first connecting column 202 and the second connecting column 205 are in the same linear axial direction. When the seat charging plug test machine pulls the fixed block 201 in the vertical direction to simulate the battery plug experiment, the second connecting column 205 gradually deviates from the vertical direction.

[0036] Further, before the formal simulation starts, the test device needs to be debugged, that is, the adjusting screw 300 is twisted to make the first shaft 203 and the second shaft 204 stably connected with the shaft limiting hole 101 and flexibly rotate, and then the fixed block 201 is pulled up and down in the vertical direction to verify whether the battery 500 can be accurately reset. This process is manually operated. After the device is debugged, the formal experiment starts.

[0037] In this embodiment, as shown in Figures 4-5 When the seat charging plug test machine pulls the fixed block 201 in the vertical direction, under the adsorption of the suction cup 206, the battery 500 forms a certain angle θ with the horizontal plane, and the size of the angle θ changes with the movement distance of the fixed block. It is worth noting that the battery plug simulation experiment specifies that the movement distance of the fixed block 201 in the vertical direction pulled by the seat charging plug test machine is 10mm, and the rotation delay is 3s. When the seat charging plug test machine pulls the fixed block 201 in the vertical direction, the angle θ gradually increases. When the position of the fixed block 201 rises to 10mm in the vertical direction, the angle θ is maximum at this time, which makes the battery 500 unable to power the electronic device but does not completely separate from the battery installation slot of the electronic device (that is, the purpose of disassembling the battery is achieved at this time). When the time reaches 3s, the seat charging plug test machine pulls the fixed block 201 in the vertical direction, and the angle θ gradually decreases until the battery 500 is completely returned to the battery installation slot of the electronic device. At this time, the angle θ disappears, and the second connecting column 205 is in the same linear axial direction with the first connecting column 202.

[0038] Due to the influence of the gravity of the battery 500, the end of the second connecting column 205 connected with the suction cup 206 gradually deviates from the vertical direction and forms a certain angle γ with the vertical direction, which is used to compensate the influence of the deviation of the angle θ in the horizontal direction in the vertical direction, so that the physical center of the whole battery plug test device does not deviate. The change mode of the size of the angle γ is the same as that of the angle θ, and the angle γ changes synchronously with the angle θ during the movement of the fixed block 201. Therefore, at the same time, the size of the angle γ is equal to that of the angle θ.

[0039] In the embodiment, the battery plug-pull experiment also provides that the seat charging plug-pull testing machine pulls the fixed block 201 to move up and down in the vertical direction, so as to simulate that the number of times of battery plug-pull is adjustable between 3000 and 5000, the movement speed of the fixed block 201 is 1000 mm / min, and the test interval of each time is 2 s.

[0040] Finally, it should be noted that: the above embodiments are only used to illustrate the technical solutions of the present application, and not to limit them; although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that: it can still modify the technical solutions recorded in the foregoing embodiments, or make equivalent replacement for part of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present application.
