Description

Technical Field

[0001] This utility model relates to the field of power supply technology, specifically to an outer frame structure for a power supply. Background Technology

[0002] Power supplies play a crucial role in electronic devices, their primary function being to provide the electrical energy required by these devices. Power supplies not only provide a basic power supply but also ensure that the voltage supplied to the devices is stable and reliable.

[0003] Power supply is a general concept; any device that can provide current can be called a power supply. A battery is a type of power supply. Electric vehicle batteries on the market have a port on the bottom. A port means that charging and discharging use the same interface. The battery can be placed in the matching space of the electric vehicle or the matching space of the power supply box, and the corresponding plug is inserted into the port to achieve discharging or charging connection. Because it is located at the bottom, it does not provide protection. During the charging process, the battery can be placed directly on the ground. If there is water or snow on the ground, the port will become damp and easily corroded and damaged. Utility Model Content

[0004] The purpose of this utility model is to provide a power supply frame structure that uses a shield to cover the lithium battery port, making it less likely for the inside of the lithium battery port to become damp, thereby improving the protection effect and solving the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a power supply frame structure, including a housing and a cover structure installed at the bottom of the housing, wherein the top and bottom of the housing are both open, and a cover structure is installed at both the top and bottom of the housing; the cover structure includes a trapezoidal block, a sliding rod, and a cover plate, the housing has two parallel cover plates, the adjacent side walls of the two cover plates overlap, and a sliding rod is fixedly connected to each adjacent side wall, the other end of the sliding rod slides through the side wall of the housing, and the other end is fixedly connected to the trapezoidal block, the housing has a placement groove at the position of the trapezoidal block, and a pad frame is fixedly installed on the housing above the cover plate.

[0006] Preferably, a retaining ring is fixedly sleeved on the outer side wall of the slide rod near the center position, and a spring is sleeved around the end of the slide rod near the housing, with the spring positioned between the retaining ring and the inner side wall of the housing.

[0007] Preferably, a baffle is fixedly fitted at the through end of the slide bar. The baffle matches the placement groove and can seal the outside of the placement groove, thereby preventing external ground gravel or soil from falling in and causing blockage of the placement groove. Over time, this can easily prevent the trapezoidal block from moving into the placement groove.

[0008] Preferably, rectangular notches are provided on the adjacent sidewalls of the two shields, and the two gaps are misaligned after contact, which increases the sealing and waterproofing effect.

[0009] Preferably, the sealing structure includes a cover plate, with matching cover plates at the top and bottom of the housing, matching screw holes on the side wall of the housing and the cover plate, and matching bolts inside the screw holes. A groove is provided at the center of the top cover plate, and a pull ring is fixedly connected to the groove. The pull ring is located inside the groove, reducing the space occupied by the pull ring directly outside the housing and reducing the overall space occupied. An insertion port is provided at the bottom cover plate position.

[0010] Preferably, a sealing frame is fixedly connected to the cover plate near the side wall of the housing, and frame-shaped grooves are provided on the top and bottom side walls of the housing, which increases the sealing performance of the cover plate during the closing process and plays a positioning role when the cover is closed.

[0011] Compared with the prior art, the beneficial effects of this utility model are: the cover shields the lithium battery port, so that if the staff accidentally places the casing on a damp ground, the inside of the lithium battery port will not easily become damp, thus improving the protection. The covering operation does not require manual operation, making the operation more convenient. In addition, the casing must be taken out from the matching volume, so the lithium battery port can be covered and protected at any time. Attached Figure Description

Detailed Implementation

[0018] 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.

[0019] Please see Figure 1 , Figure 2 , Figure 3 The diagram illustrates a power supply frame structure, including a housing 1 and a cover structure 3 installed at the bottom of the housing 1. The cover structure 3 includes a trapezoidal block 303, a sliding rod 305, and a cover plate 306. The housing 1 has two parallel cover plates 306, with adjacent sidewalls of the two cover plates 306 overlapping. Each adjacent sidewall is fixedly connected to a sliding rod 305. One end of the sliding rod 305 slides through the sidewall of the housing 1, and the other end is fixedly connected to the trapezoidal block 303. The housing 1 has placement slots 302 at the positions of the trapezoidal blocks 303. A pad frame 301 is fixedly installed above the cover plate 306 on the housing 1. The four outer sidewalls of the pad frame 301 can be fitted and fixedly connected to the inner side of the housing 1 to support the placement of the lithium battery and prevent the lithium battery from squeezing the related components of the cover structure 3 after placement. It should be noted that: the entire... A lithium battery can be installed inside the housing 1. The bottom of the lithium battery can be placed on the surface of the pad frame 301. The lithium battery port position matches the area of ​​the cover plate 306. During the entire lithium battery charging or charging process, the housing 1 is placed into the matching volume. The trapezoidal blocks 303 on both outer sides of the housing 1 are compressed, thereby causing the corresponding compression slide rod 305 to slide horizontally. The two cover plates 306 move in opposite directions, so that the cover plates 306 no longer block the lithium battery port position, allowing the corresponding plug to make contact, thus completing the charging or charging process. When the port position is not in use, the trapezoidal blocks 303 are pulled outwards from the housing 1, causing the cover plates 306 to block the lithium battery port position, preventing dust from falling into the port position, thus protecting the lithium battery port position.

[0020] Please see Figure 1 , Figure 2 and Figure 3A retaining ring 308 is fixedly sleeved on the outer wall of the slide rod 305 near the center position. A spring 304 is wrapped around one end of the slide rod 305 near the housing 1. The spring 304 is located between the retaining ring 308 and the inner wall of the housing 1. It should be noted that by using the spring 304, there is no need to manually pull the trapezoidal block 303. The housing 1 is placed into the matching volume. By squeezing the trapezoidal block 303, the slide rod 305 is displaced, which can compress the spring 304. When the entire housing 1 is taken out from the matching volume, the spring 304 rebounds and covers the lithium battery port with the cover plate 306. If the staff accidentally places the housing 1 on a damp ground, it is less likely to cause the lithium battery port to become damp, thus improving the protection. The covering operation does not require manual operation, making the operation more convenient. The housing 1 is always taken out from the matching volume, and the lithium battery port can be covered for protection at any time.

[0021] See Figure 2 The sliding rod 305 is also fixedly fitted with a baffle 307 at its through end. The baffle 307 matches the placement groove 302. The placement groove 302 is for the trapezoidal block 303 to move into. When the trapezoidal block 303 moves out of the side of the placement groove 302, the outer side of the placement groove 302 is open. The baffle 307 can close the outer side of the placement groove 302, thereby preventing external ground gravel or soil from falling in and causing the placement groove 302 to be blocked. Over time, this can easily prevent the trapezoidal block 303 from moving into the placement groove 302.

[0022] See Figure 3 The two shields 306 have rectangular notches 309 on their adjacent sidewalls, which makes the contact position of the shields 307 misaligned. After contact, the two gaps are misaligned, which increases the sealing and waterproofing effect.

[0023] See Figure 4 The top and bottom of the housing 1 are both open, and a cover structure 2 is installed on both the top and bottom of the housing 1. The cover structure 2 includes a cover plate 202. The top and bottom of the housing 1 are provided with matching cover plates 202. The side wall of the housing 1 and the cover plate 202 are provided with matching screw holes 207. Matching bolts 205 are provided inside the screw holes 207. The center of the top cover plate 202 is provided with a groove 203. A pull ring 204 is fixedly connected to the groove 203. The bottom cover plate 202 is provided with an insertion port 208 at the position of the cover plate 306. It should be noted that the pull ring 204 is set inside the groove 203, which reduces the space occupied by the pull ring 204 directly on the outside of the housing 1 and reduces the overall space occupied.

[0024] See Figure 5A sealing frame 206 is fixedly connected to the cover plate 202 near the side wall of the housing 1. The top and bottom side walls of the housing 1 are provided with frame-shaped grooves 201. It should be noted that the sealing frame 206 is set inside the frame-shaped grooves 201, which increases the sealing performance of the cover plate 202 during the closing process and plays a positioning role when the cover is closed. This ensures that the side wall of the housing 1 and the cover plate 202 are provided with matching screw holes 207, which makes it less likely to produce misaligned holes and thus reduce the complexity of installation.

[0025] Working principle: When the housing 1 is placed into the charging box for energy storage or the shared bicycle base for power supply, it is placed into the matching space. By squeezing the trapezoidal block 303, the slide bar 305 is displaced, which compresses the spring 304. When the entire housing 1 is removed from the matching volume, the spring 304 rebounds and the cover plate 306 blocks the lithium battery port. This causes the slide bar 305 to slide horizontally, and the two cover plates 306 move in opposite directions, so that the cover plates 306 are no longer blocking the lithium battery port, allowing the corresponding plug to make contact, thereby completing the power supply or energy storage. When the entire housing 1 is removed from the matching volume, the spring 304 rebounds and the cover plate 306 blocks the lithium battery port.
