Description

Technical Field

[0001] This utility model relates to the technical field of charging piles, and in particular to a short-circuit detection mechanism for DC charging pile output. Background Technology

[0002] A charging station is a device that provides electrical energy to electric vehicles, enabling them to store enough electricity to support their operation. Charging stations can be divided into AC charging stations and DC charging stations. AC charging stations convert AC power to DC power through an onboard charger, resulting in a slower charging speed, suitable for home or office use. DC charging stations, on the other hand, directly provide DC power, resulting in a faster charging speed, suitable for quickly replenishing power during long-distance travel. Because DC charging stations charge faster, they are more prone to circuit breaks than AC charging stations. Using a short-circuited DC charging station can damage the car battery. Therefore, it is necessary to test the circuit of the charging station before charging. Hence, a DC charging station output short-circuit detection mechanism is particularly needed.

[0003] However, most existing DC charging pile output short circuit detection mechanisms do not have a detection structure, so a short circuit tester is needed to test the circuit. However, when using the tester, it cannot be fixed quickly and may shake during testing, causing the connection between the tester and the charging head to become loose, which will affect the accuracy of the test. Utility Model Content

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. 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 protection scope of the present utility model.

[0020] Please see Figure 1-4 This utility model provides a technical solution: a DC charging pile output short circuit detection mechanism, including a DC charging pile 1, a detection mechanism 2 is provided at one end of the DC charging pile 1, and a moving mechanism 3 is provided at the lower end of the DC charging pile 1.

[0021] The testing mechanism 2 includes a connecting cable 201, a charging head 202, a mounting bracket 203, a mounting plate 204, a receiving slot 205, a spring 206, a locking block 207, a connecting rod 208, a mounting block 209, a slot 210, and a short-circuit detector 211. A connecting cable 201 is provided on one side of the DC charging pile 1, and a charging head 202 is fixedly installed at one end of the connecting cable 201. A mounting bracket 203 is fixedly installed on one side of the DC charging pile 1, and a short-circuit detector 211 is also fixedly installed on one side of the DC charging pile 1. Mounting plate 204 has an inner wall with a receiving groove 205. A spring 206 is fixedly installed inside the receiving groove 205. One end of the spring 206 is fixedly connected to a locking block 207. A connecting rod 208 is fixedly connected to one side of the locking block 207. One end of the mounting plate 204 is connected to a mounting block 209. A slot 210 is formed on one side of the mounting block 209. A short circuit detector 211 is fixedly connected to one side of the mounting block 209. A charging cable 201 is used for connection. The arrangement of the head 202, placement bracket 203, mounting plate 204, receiving groove 205, spring 206, locking block 207, connecting rod 208, mounting block 209, slot 210, and short-circuit detector 211 is as follows: When testing the circuit, the mounting block 209 is placed into the mounting plate 204. At this time, the locking block 207 will enter the slot 210, and under the pushing force of the spring 206, the locking block 207 will be fixed in the slot 210. At this time, the mounting block 209 will be fixed to the mounting plate 204. In step 4, the short circuit detector 211 is fixed on the mounting plate 204, ensuring stability during testing. The connection between the charging head 202 and the short circuit detector 211 will not loosen, resulting in more accurate test results. To remove the short circuit detector 211, pull the connecting rod 208. The connecting rod 208 can pull the locking block 207 out of the locking slot 210, allowing the mounting block 209 to leave the mounting plate 204, and the short circuit detector 211 can be quickly removed.

[0022] Furthermore, the dimensions of the card block 207 and the card slot 210 are matched. The card block 207 and the mounting block 209 form a locking structure through the card slot 210. With the setting of the card block 207 and the card slot 210, when the card block 207 is fixed in the card slot 210, the mounting block 209 will be fixed in the mounting plate 204, and the short circuit detector 211 will also be fixed on the mounting plate 204.

[0023] Furthermore, the locking block 207 forms a telescopic structure with the mounting plate 204 via the spring 206. With the spring 206, the locking block 207 will be pushed into the locking groove 210 under the thrust of the spring 206, thereby fixing the mounting block 209.

[0024] Furthermore, the moving mechanism 3 includes a moving base 301, a sliding groove 302, a connecting groove 303, a slider 304, a screw 305, a nut 306, a caster wheel 307, a fixing frame 308, and bolts 309. The moving base 301 is fixedly installed at the lower end of the DC charging pile 1. The moving base 301 has a sliding groove 302 inside, and a connecting groove 303 is opened on one side surface of the moving base 301. A slider 304 is arranged inside the sliding groove 302. A screw 305 is welded to one side surface of the slider 304. A nut 306 is threaded to one end of the screw 305. A caster wheel 307 is fixedly connected to one side surface of the slider 304. The moving mechanism 3 connects to the moving base 301, the sliding groove 302, the connecting groove 303, and the slider 304. 4. The screw 305, nut 306, caster wheel 307, fixing bracket 308, and bolt 309 are configured so that when the DC charging pile 1 needs to be moved and transported, the nut 306 is loosened, allowing the slider 304 to slide down in the slide groove 302. At this time, the caster wheel 307 is moved to the outside of the moving seat 301. Then, the nut 306 is tightened to fix it. In this way, the moving seat 301 can move the DC charging pile 1. After moving to the designated position, the nut 306 is loosened again, allowing the slider 304 to move into the moving seat 301 with the caster wheel 307. At this time, the fixing bracket 308 can be fixed to the ground with the bolt 309, and the moving seat 301 and the DC charging pile 1 are also fixed to the ground.

[0025] Furthermore, a fixing bracket 308 is fixedly installed on both sides of the mobile base 301. A bolt 309 is provided at one end of the fixing bracket 308. By setting the bolt 309, the fixing bracket 308 can be fixed to the ground, and the mobile base 301 and the DC charging pile 1 are also fixed to the ground.

[0026] Furthermore, the slider 304 forms a sliding structure with the movable seat 301 through the sliding groove 302, and the screw 305 forms a sliding structure with the movable seat 301 through the connecting groove 303. With the setting of the sliding groove 302 and the slider 304, when the slider 304 slides in the sliding groove 302, the caster wheel 307 will move in and out of the movable seat 301.

[0027] Furthermore, one end of the screw 305 passes through the connecting groove 303 and is threadedly connected to the nut 306. Through the setting of the screw 305 and the nut 306, the position of the slider 304 can be fixed, and the position of the universal wheel 307 is also fixed.

[0028] Working principle: When testing the circuit, the mounting block 209 is placed into the mounting plate 204. At this time, the locking block 207 will enter the slot 210, and under the push of the spring 206, the locking block 207 will be fixed in the slot 210. The mounting block 209 will then be fixed in the mounting plate 204, thus fixing the short-circuit detector 211 to the mounting plate 204. This ensures the short-circuit detector 211 is stable during testing, preventing loosening at the connection between the charging head 202 and the short-circuit detector 211, resulting in more accurate test results. To remove the short-circuit detector 211, pull the connecting rod 208. The connecting rod 208 will pull the locking block 207 out of the slot 210, allowing the mounting block 209 to leave the mounting plate 204. 4. The short circuit detector 211 is quickly removed. When the DC charging pile 1 needs to be moved and transported, loosen the nut 306 and let the slider 304 slide down in the slide groove 302. At this time, the universal wheel 307 is moved to the outside of the moving seat 301. Then tighten the nut 306 to fix it. In this way, the moving seat 301 can move the DC charging pile 1. After moving to the designated position, loosen the nut 306 again and let the slider 304 move into the moving seat 301 with the universal wheel 307. At this time, the fixing frame 308 can be fixed to the ground with the bolt 309. The moving seat 301 and the DC charging pile 1 are then fixed to the ground. The model of the short circuit detector 211 is XL-942.
