Description

Technical Field

[0001] This utility model relates to the field of charging pile technology, specifically a charging pile structure based on modular assembly. Background Technology

[0002] Charging stations are infrastructure that provides power to electric vehicles. They transmit power from the grid to the vehicle's battery through a charging interface to support vehicle operation. However, existing charging stations are designed as an integrated unit, making them inconvenient to maintain.

[0003] To overcome the aforementioned shortcomings, a Chinese patent (publication number: CN219821234U) discloses a modular, easy-to-maintain charging pile. This pile includes an internal housing with a door that can open or close the housing. An AC input module is detachably housed within the housing; a charging module is detachably housed within the housing and connected to the AC input module; a DC output module is detachably housed within the housing and connected to the charging module; a control module is detachably housed within the housing and connected to the charging module; a metering module is detachably housed within the housing and connected to the DC output module; and a human-machine interface module is detachably housed within the housing and connected to the metering module. By detachably housing the AC input module, charging module, DC output module, control module, metering module, and human-machine interface module within the housing, the charging pile can be easily repaired and maintained in case of malfunction, reducing the difficulty of repair and maintenance.

[0004] While existing technologies can overcome the shortcomings mentioned above, other problems still exist in their operation: due to their maintenance requirements, existing charging piles use modular design of their internal electronic components to facilitate the maintenance of individual modules, but the overall fixed installation of the charging pile's electronic components is still difficult to disassemble. Utility Model Content

[0005] The purpose of this utility model is to provide a charging pile structure based on modular assembly, so as to solve the problem in the above-mentioned background technology that the existing charging piles facilitate the maintenance of individual modules by modular design of their internal electronic components, but the overall fixed installation of the charging pile electronic components is still difficult to disassemble.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a charging pile structure based on modular assembly, including a cabinet, wherein an installation ring is fixedly connected to the bottom of the cabinet, and a fixing ring is installed at the bottom of the installation ring;

[0007] The top side of the fixing ring is provided with four equally spaced arc-shaped mounting holes, and the bottom side of the outer side of the mounting ring is provided with four equally spaced mounting holes. The mounting ring and the fixing ring are connected to each other by bolts passing through the mounting holes and the arc-shaped mounting holes.

[0008] The cabinet is slidably connected to a mounting frame structure, which consists of a fixing plate and a mounting rod.

[0009] Preferably, the mounting rods are fixedly connected to the four corners of the inner side of the fixing plate, and two parallel mounting brackets are fixedly connected between every two mounting rods. The fixing plate is provided with an embedded handle in the middle.

[0010] Preferably, a pulley assembly is fixedly connected to the outer side of the end of the mounting rod away from the fixing plate. The pulley assembly consists of two pulleys rotatably connected to the end of the mounting rod, and a guide groove is formed between the pulleys and the mounting rod.

[0011] Preferably, the fixing plate is slidably connected to the middle of the top and bottom of the fixing plate, and the cabinet has a threaded hole aligned with the two hand-tightening bolts on the rear side. The hand-tightening bolts pass through the top and bottom of the fixing plate and are threaded into the threaded hole.

[0012] Preferably, symmetrically distributed guide rods are fixedly connected to the upper and lower ends of the cabinet, and the guide rods are slidably connected to the guide grooves of the pulley group. An interactive panel is installed on the upper front side of the cabinet.

[0013] Preferably, a mounting base and a terminal block are fixedly connected to both sides of the cabinet, a cable is fixedly connected to the outer end of the terminal block, and a charging gun that is snapped into the mounting base is fixedly connected to the end of the cable.

[0014] Preferably, the cabinet has air intake holes at both the top and bottom of both sides, and exhaust holes at equal intervals on both sides of the cabinet. Inside the cabinet, air intake fans aligned with the air intake holes are fixedly connected to both the top and bottom of the cabinet.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] This modular assembly-based charging pile structure achieves flexible adjustment of the installation angle through the arc-shaped hole design of the mounting ring and the fixing ring. After the fixing ring is pre-embedded, the mounting ring can compensate for the position deviation of the ground foundation by rotation. Its three-point rigid fixing design ensures stability, which is consistent with the advantages of modular design mentioned in the search results, such as reducing installation time and improving flexibility.

[0017] The guide rod pulley system and the hand-tightening bolt locking structure allow the entire mounting frame to be pulled out for maintenance. The modular electronic components are electrically connected through quick-connect terminals, eliminating the need to disconnect wires one by one during maintenance.

[0018] The upper and lower air intakes form a dual-path flow of cold air, which passes through the gap between the upper and lower modules and then converges and is discharged, forming a vertical and horizontal composite airflow path. This improves the heat dissipation efficiency compared to the traditional single-path airflow. The combination of the double-layer air intake fan and the central heat dissipation channel can still maintain smooth airflow even in scenarios with densely packed electronic components. At the same time, the exhaust vents are distributed on both sides of the cabinet to prevent hot air from flowing back. Attached Figure Description

Detailed Implementation

[0026] 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.

[0027] Example 1: Please refer to Figure 1 - Figure 4This utility model provides the following technical solution: a charging pile structure based on modular assembly, including a cabinet 1, a mounting ring 2 fixedly connected to the bottom of the cabinet 1, and a fixing ring 3 installed at the bottom of the mounting ring 2; the top side of the fixing ring 3 is provided with four equally spaced arc-shaped mounting holes, and the bottom side of the outer side of the mounting ring 2 is provided with four equally spaced mounting holes; the mounting ring 2 and the fixing ring 3 are connected to each other by bolts passing through the mounting holes and the arc-shaped mounting holes; a mounting frame structure is slidably connected to the rear side of the cabinet 1, the mounting frame structure is composed of a fixing plate 4 and mounting rods 5; the mounting rods 5 are fixedly connected to the four corners of the inner side of the fixing plate 4, and two parallel mounting brackets 6 are fixedly connected between every two mounting rods 5. The fixed plate 4 has an embedded handle 7 in the middle; the outer side of the mounting rod 5 away from the fixed plate 4 is fixedly connected to a pulley group 8, which consists of two pulleys rotatably connected to the end of the mounting rod 5, and a guide groove is formed between the pulleys and the mounting rod 5; the fixed plate 4 has a hand-tightening bolt 9 slidably connected to the middle of the top and bottom; the cabinet 1 has a threaded hole 10 aligned with the two hand-tightening bolts 9 on the rear side, and the hand-tightening bolt 9 passes through the top and bottom of the fixed plate 4 and is threaded into the threaded hole 10; the cabinet 1 has symmetrically distributed guide rods 11 fixedly connected to the upper and lower ends, and the guide rods 11 are slidably connected in the guide groove of the pulley group 8; the cabinet 1 has an interactive panel 12 installed on the upper front side.

[0028] The bottom of the cabinet 1 adopts a combined connection structure of mounting ring 2 and fixing ring 3. The four arc-shaped mounting holes on the top of the fixing ring 3 are connected to the positioning holes of the mounting ring 2 by bolts to form an adjustable connection. The arc-shaped hole design allows the mounting ring 2 to be rotated and adjusted at a certain angle relative to the fixing ring 3, effectively compensating for the position deviation of the pre-embedded foundation on the ground. After the fixing ring 3 is fixed by the ground pouring, the operator can make a fine adjustment of the angle by rotating the mounting ring 2, and then achieve three-point rigid fixation by through bolts, which not only ensures the installation stability but also improves the adaptability of on-site construction.

[0029] The guide rod 11 set on the rear side of the cabinet 1 forms a sliding engagement system with the pulley group 8 of the mounting frame structure. The four pulley groups 8, each consisting of double pulleys, are respectively embedded in the end of the mounting rod 5, forming a three-point contact sliding with the longitudinally arranged guide rod 11. When the charging module needs to be installed, the operator holds the embedded handle 7 and pushes the mounting frame structure smoothly into the cabinet 1 along the guide rod 11 until the fixing plate 4 is completely attached to the rear wall of the cabinet. At this time, the hand-tightening bolts 9 at the top and bottom of the fixing plate 4 automatically align with the threaded holes 10 on the rear side of the cabinet 1. The mechanical locking between the electrical cabinet and the frame structure can be completed by manually tightening them.

[0030] The electronic components mounted on the mounting bracket 6 are arranged in a double-row vertical layout, which facilitates maintenance of the electronic components on the mounting bracket 6 when the mounting frame structure is removed. At the same time, all electronic components inside the cabinet 1 are interconnected through ribbon cables, so that the connection of each electronic component is not affected when the mounting frame structure moves. Modular expansion is achieved through standardized mounting brackets 6. The spacing between each set of mounting brackets 6 is designed to be standard and compatible with charging modules of different brands. The quick-connect terminals between the mounting brackets 6 automatically complete the electrical connection. During maintenance, simply loosen the hand-tightening bolts 9, and the entire mounting frame structure can be smoothly pulled out of the cabinet 1 along the guide rod 11.

[0031] Example 2: Based on Example 1, please refer to... Figure 5 and Figure 6 The following structure was also disclosed: mounting bases 13 and wiring terminals 14 are fixedly connected to both sides of the cabinet 1, a cable 15 is fixedly connected to the outer end of the wiring terminal 14, and a charging gun 16 that is snapped into the mounting base 13 is fixedly connected to the end of the cable 15; air intake holes 17 are provided at the top and bottom of both sides of the cabinet 1, and exhaust holes 18 are provided at equal intervals on both sides of the cabinet 1; and air intake fans 19 aligned with the air intake holes 17 are fixedly connected to the top and bottom of the cabinet 1.

[0032] The air intake holes 17 at the top and bottom of both sides of the cabinet 1 form a forced convection with the double-layered air intake fans 19 inside. The electronic components mounted on the mounting bracket 6 are arranged in a double-row vertical layout, forming a central heat dissipation channel. When the air intake fan 19 is started, the external cold air enters from the top and bottom air intake holes 17 in two directions. The upper airflow passes through the module gaps of the upper mounting bracket 6, and the lower airflow flows through the lower mounting module. The two airflows converge in the middle of the cabinet 1 and are discharged through the exhaust holes 18 on both sides. The heat dissipation efficiency is improved through the combined vertical and horizontal airflow path.
