Description

Technical Field

[0001] This utility model relates to the field of charging pile technology, specifically to a low-speed electric vehicle charging pile with high protection performance. Background Technology

[0002] Electric vehicle charging stations are power stations for electric vehicles, similar in function to gas pumps at gas stations. Each charging station is equipped with a charging plug, and can charge various models of electric vehicles according to different voltage levels.

[0003] Currently, various low-speed electric vehicle charging piles exist on the market. For example, a charging pile with Chinese patent number CN208760455U includes two main parts: a housing and a control device. The housing comprises a housing body and a panel. The panel and housing body are assembled using an insert-and-fasten method, which is convenient and compact. The screw holes are located on the mounting base plate of the housing body, inside the housing. This allows the housing to be fixed to the corresponding mounting structure with screws during installation, without the screws being exposed, resulting in an aesthetically pleasing appearance and eliminating the need for mounting ears with screw holes on the outside of the housing. While the structure is simplified, this technical solution still has some shortcomings. For example, the electronic panel lacks adequate protection. Although the control device and the housing are assembled using an insert-and-buckle method, which allows for quick assembly, some parts are prone to aging, potentially leading to insecure mounting and equipment falling and being damaged. Furthermore, since charging stations are electrical devices, they should not come into contact with water. This design relies solely on the top cover as a rain shield, which is insufficient. Rainwater or other water-based substances can still come into contact with the interior, causing equipment malfunctions or damage. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a low-speed electric vehicle charging pile with high protective performance. It has the advantages of superior fixing performance and stronger protection performance, and solves the problems of water dripping into the charging pile from the cover and easy aging of fastening parts.

[0005] To achieve the above-mentioned superior fixation performance and stronger protection performance, this utility model provides the following technical solution: a low-speed electric vehicle charging pile with high protection performance, including an equipment box and a charging control device. Mounting plates are fixedly installed on both the left and right sides of the equipment box, and fixing mechanisms are provided inside the two mounting plates. The charging control device is movably installed inside the equipment box.

[0006] The fixing mechanism includes a clamping tube, which is fixedly installed inside the mounting plate. A positioning plate is fixedly installed inside the clamping tube. A locking pin is fixedly connected to the inner wall of the positioning plate, passing through the inside of the clamping tube and extending into the equipment box. A movable plate is fixedly connected to the outer end of the locking pin, which is located inside the clamping tube. A spring is fixedly installed on the opposite side of the movable plate and the positioning plate. A pull ring is fixedly installed on the end of the locking pin away from the equipment box.

[0007] Furthermore, a connecting block is fixedly installed inside the charging control device, and a limiting rod is fixedly installed at the bottom of the connecting block. The outer end of the limiting rod is engaged with one end of the locking pin that extends into the equipment box.

[0008] Furthermore, a fixing box is threadedly connected to the top of the equipment box, an upper baffle is fixedly installed on the front side of the fixing box, two partitions are fixedly installed at the bottom of the upper baffle, and two mounting brackets are fixedly installed on the front side of the equipment box, with the tops of the two mounting brackets movably connected to the bottoms of the two partitions.

[0009] Furthermore, a load-bearing plate is fixedly installed at the bottom of the equipment box, a limit post is fixedly installed at the top of the load-bearing plate, and a locking hole adapted to the limit post is opened at the bottom of the charging control device.

[0010] Furthermore, two T-shaped limiting plates are fixedly installed inside the equipment box, and two limiting slide plates are fixedly installed outside the charging control device. Each of the two limiting slide plates has a groove that matches the T-shaped limiting plates.

[0011] Furthermore, the inner wall of the equipment box is provided with heat dissipation holes and mounting holes.

[0012] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0013] 1. This low-speed electric vehicle charging pile with high protection performance has a fixing mechanism. When installing the charging control device, pulling the pull rings on both sides causes the locking pin to retract into the locking tube. When it retracts to a certain extent, the charging control device is inserted through the hole at the top of the equipment box. When the bottom of the charging control device contacts the load-bearing plate, releasing the pull rings will cause the locking pin to lock into the charging control device through the elasticity of the internal spring. At the same time, the limit rod inside the charging control device will also limit the locking pin, resulting in better fixing effect. In addition, if the equipment malfunctions and needs maintenance, this mechanism can quickly help the staff to install and disassemble, and the operation is also relatively simple.

[0014] 2. This low-speed electric vehicle charging pile with high protection performance is equipped with an equipment box, a fixing box, an upper baffle, a partition, and a mounting bracket. The upper baffle, partition, and mounting bracket can protect the equipment box from rain and other factors to a greater extent. At the same time, the equipment box can protect the internal charging control device from physical factors. These structures can protect the internal charging control device to the greatest extent, making the entire equipment safer. Attached Figure Description

[0022] 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.

[0023] Please see Figure 1-6In this embodiment, a low-speed electric vehicle charging pile with high protection performance includes an equipment box 1 and a charging control device 4. Mounting plates 2 are fixedly installed on both the left and right sides of the equipment box 1. Fixing mechanisms 3 are provided inside the two mounting plates 2. The charging control device 4 is movably installed inside the equipment box 1.

[0024] The fixing mechanism 3 includes a clamping tube 301. The clamping tube 301 is fixedly installed inside the mounting plate 2. A positioning plate 302 is fixedly installed inside the clamping tube 301. A locking pin 304, which passes through the inside of the clamping tube 301 and extends into the equipment box 1, is fixedly connected to the inner wall of the positioning plate 302. A movable plate 303 is fixedly connected to one end of the locking pin 304 located inside the clamping tube 301. A spring 305 is fixedly installed on the opposite side of the movable plate 303 and the positioning plate 302. A pull ring 306 is fixedly installed on the end of the locking pin 304 away from the equipment box 1. When the charging control device 4 is installed, pulling the pull rings 306 on both sides causes the locking pin 304 to retract into the clamping tube 301, thus providing charging control. Device 4 has sufficient space for placement. A connecting block 401 is fixedly installed inside the charging control device 4. A limit rod 402 is fixedly installed at the bottom of the connecting block 401. The outer end of the limit rod 402 is engaged with the end of the locking pin 304 that extends into the equipment box 1. After the charging control device 4 is placed, the pull ring 306 is released, and the locking pin 304 will be engaged into the charging control device 4 by the elasticity of the internal spring 305. At the same time, the limit rod 402 inside the charging control device 4 will also limit the locking pin 304, resulting in a better fixing effect. In addition, if the equipment malfunctions and needs to be repaired, this mechanism can quickly help the staff to load and unload the equipment, and the operation is also relatively simple.

[0025] In the implementation of the case, the top of the equipment box 1 is threadedly connected to the fixing box 5. The connection between the equipment box 1 and the fixing box 5 is located on the mounting plates on the left and right sides of the equipment box 1. The top of the equipment box 1 is open. Two holes are reserved on the rear side of the fixing box 5 to facilitate the connection between the fixing box 5 and the equipment box 1. The front side of the fixing box 5 is fixedly installed with an upper baffle 6. The bottom of the upper baffle 6 is fixedly installed with two partitions 7. The front side of the equipment box 1 is fixedly installed with two mounting brackets 8. The top of the two mounting brackets 8 is movably connected to the bottom of the two partitions 7. The upper baffle 6, partitions 7 and mounting brackets 8 can protect the equipment box 1 from rain and other factors to a greater extent.

[0026] In the implementation of the case, a load-bearing plate 101 is fixedly installed on the bottom of the equipment box 1, and a limiting post 102 is fixedly installed on the top of the load-bearing plate 101. The bottom of the charging control device 4 is provided with a locking hole that matches the limiting post 102. When the charging control device 4 is placed, the limiting post 102 can be inserted into the bottom of the charging control device 4 to make it more stable.

[0027] In the implementation of the case, two T-shaped limiting plates 103 are fixedly installed inside the equipment box 1, and two limiting slide plates 403 are fixedly installed outside the charging control device 4. Both limiting slide plates 403 are provided with sliding grooves that are compatible with the T-shaped limiting plates 103. When the charging control device 4 is placed, the T-shaped limiting plates 103 and the sliding grooves can provide stability for the equipment and provide guidance for the installation of the charging control device 4, thus preventing displacement during installation.

[0028] In the implementation of the case, the inner wall of the equipment box 1 is provided with heat dissipation holes 104 and mounting holes 105. The heat dissipation holes 104 can help the charging control device 4 dissipate heat, and the reserved mounting holes 105 are mainly used for the installation and fixation of the entire equipment.

[0029] When implementing this procedure, please follow these steps:

[0030] 1) First, fix the equipment box 1 to the wall or pole surface through the mounting holes 105;

[0031] 2) Then separate the equipment box 1 from the fixing box 5, exposing the opening at the top of the equipment box 1;

[0032] 3) Then insert the charging control device 4 through the opening at the top of the equipment box 1, and at the same time adjust the fixing mechanisms 3 on the left and right sides and the T-shaped limiting plate 103 inside the equipment box 1.

[0033] 4) Finally, after installing the charging control device 4, align the two partitions 7 with the two mounting brackets 8, snap them together, and then install the fixing box 5.

[0034] In summary, this low-speed electric vehicle charging pile with high protection performance, through the setting of the fixing mechanism 3, when installing the charging control device 4, by pulling the pull rings 306 on both sides, the locking pin 304 is retracted into the locking tube 301. When it is retracted to a certain extent, the charging control device 4 is inserted through the hole at the top of the equipment box 1. When the bottom of the charging control device 4 contacts the load-bearing plate 101, the pull rings 306 are released, and the locking pin 304 will be locked into the charging control device 4 by the elasticity of the internal spring 305. At the same time, the limiting rod 402 inside the charging control device 4 will also limit the locking pin 304, resulting in a better fixing effect. In addition, if the equipment malfunctions and needs to be repaired, this mechanism can quickly help the staff to install and disassemble, and the operation is also relatively simple. It solves the problem of the control device and the housing using a snap-fit ​​assembly method in the previous technical solution. Although it can achieve quick assembly, some parts are prone to aging, which may lead to the equipment not being securely fixed and thus causing the equipment to fall and be damaged.

[0035] Furthermore, by setting up the equipment box 1, fixing box 5, upper baffle 6, partition 7, and mounting bracket 8, the upper baffle 6, partition 7, and mounting bracket 8 can protect the equipment box 1 from rain and other factors to a greater extent. At the same time, the equipment box 1 can protect the internal charging control device 4 from physical factors. These structures can protect the internal charging control device 4 to the greatest extent, making the entire equipment safer. This solves the problem that charging piles are all electrical equipment, especially in contact with water. The current design only relies on the upper cover as a rain shield, which is not very protective. Rainwater or other water-like substances can still come into contact with the interior, which can lead to equipment failure or damage.
