Description
Technical Field
[0001] This invention relates to the field of charging pile technology, and in particular to a convenient charging module structure for charging piles. Background Technology
[0002] With the increasing popularity of new energy vehicles, the demand for convenient daily charging is growing. Charging modules are used in DC charging equipment, and their performance directly affects the overall performance of DC charging equipment. They are also related to charging safety and other issues. As a core component of DC charging equipment for new energy vehicles, their ease of use and safety are receiving more and more attention.
[0003] Currently, existing charging modules are mainly installed and removed manually. Due to the large number of terminal pins at the end of the module and its overall weight, a tight fit is usually used to ensure contact stability and reliability. This results in significant resistance during insertion and removal, making installation very strenuous for operators with limited strength. Special tools are also required to disassemble and tighten the screws, leading to poor efficiency and quality in maintenance. Therefore, a charging module structure that is simple in design, requires no additional tools, is convenient and labor-saving, safe and reliable, and easy to install and maintain has become an urgent technical problem to be solved. Summary of the Invention
[0004] In view of this, the purpose of this invention is to propose a convenient charging module structure for charging piles to solve the problem of laborious plugging and unplugging of heavy charging modules.
[0005] To achieve the above objectives, the present invention provides a convenient charging module structure for a charging pile, comprising: a charging module housing detachably mounted on a cabinet along a linear direction; a left handle assembly and a right handle assembly symmetrically arranged on the charging module housing; a locking bracket assembly adapted to the left handle assembly and the right handle assembly fixedly mounted on the charging module housing; and a stop pin adapted to the left handle assembly and the right handle assembly mounted on the cabinet. The stop pin, the charging module housing, the left handle assembly, the right handle assembly, and the locking bracket assembly are mutually locked and limited to each other with the cabinet.
[0006] Preferably, the cabinet is provided with a receiving space for accommodating the charging module housing. Guide rail grooves for guiding the insertion of the charging module housing are fixedly installed on both sides of the receiving space. Multiple plug-in terminals are fixedly installed on the bottom of the charging module housing. Multiple plug-in terminal blocks that are adapted to the multiple plug-in terminals are fixedly installed on the cabinet for electrical connection when the charging module housing is inserted into the position.
[0007] Preferably, slide rails are fixedly installed on both sides of the charging module housing, and the two slide rails are slidably adapted to the two guide rail grooves in the accommodating space. Guide structures for guiding the charging module housing into the cabinet guide rail grooves are opened at both ends of the bottom of the charging module housing. A rectangular hole for the left handle assembly and the right handle assembly to pass through is opened on one side of the top of the charging module housing.
[0008] Preferably, the locking bracket assembly includes: a locking bracket body fixedly installed at the top center of one side of the charging module housing; the top of the locking bracket body is integrally formed with a stop strip and a U-shaped bracket structure; both ends of the locking bracket body are vertically inserted with top pins; a first spring is fixedly installed between the top pin and the locking bracket body; a retaining ring is fixedly installed at the bottom end of the top pin through the limiting action of the retaining ring and the cooperation of the first spring to realize the up-and-down rebound action of the top pin.
[0009] Preferably, a positioning pin is fixedly inserted between the middle part of the locking bracket body and the charging module housing, and rivets are fixedly inserted between the two sides of the middle part of the locking bracket body and the charging module housing.
[0010] Preferably, the left handle assembly includes: a left handle rotatably mounted on one top end of the charging module housing, and a left handle slidably mounted in a square groove at one end of the left handle. The left handle is adapted to the stop bar and the U-shaped bracket structure for locking and limiting the left handle assembly after it is retracted. The right handle assembly includes: a right handle rotatably mounted on the other top end of one side of the charging module housing, and a right handle slidably mounted in a square groove at one end of the right handle. The right handle is adapted to the stop bar and the U-shaped bracket structure for locking and limiting the right handle assembly after it is retracted. Two top pins are respectively linked and adapted to the left handle and the right handle, and are used to lock and limit the left handle and the right handle when they are retracted. When pushed, the left and right handle assemblies are ejected. When the left and right handles are pushed away from each other, they disengage from the stop bar and U-shaped bracket structure. Under the action of the first spring, the top pin automatically ejects the left and right handle assemblies, causing them to pop out of the rectangular hole in the charging module housing to the operating position. When the left and right handle assemblies are pushed into the rectangular hole in the charging module housing, the slots of the left and right handles engage with the stop bar on the locking bracket assembly. At the same time, the hook-shaped structures on the left and right handles engage with the two stop pins respectively, thus locking and fixing the charging module housing to the cabinet.
[0011] Preferably, a pivot is inserted between the left handle and the charging module housing, and between the right handle and the charging module housing. The pivot is used to limit the rotation center of the left and right handles on the charging module housing. Two limiting pins are fixedly installed on the charging module housing. Both the left and right handles are provided with arc-shaped holes adapted to the limiting pins. Both the left and right handles are provided with central shaft holes for the pivot to pass through.
[0012] Preferably, pan head screws are threaded into the bottom of both the left and right handles, and the two pan head screws are slidably connected to the left and right handles respectively. A second spring is embedded in the inner groove between the left and right handles and in the inner groove between the right and right handles.
[0013] Preferably, both the left and right handles are provided with arc-shaped openings for hand gripping, and both the left and right handles are provided with hook-shaped structures at the middle of their opposite ends. The hook-shaped structures are adapted to the stop pins and are used to cooperate with the stop pins to form a lever effect to provide assistance when inserting or removing the charging module housing.
[0014] Preferably, the locking bracket assembly is made of sheet metal, and the guide structure is a rounded chamfer structure with a radius of 5mm-10mm, which is used to reduce the resistance when the charging module housing is inserted into the guide rail groove, and at the same time avoid hard contact wear between the guide rail groove and the slide rail.
[0015] The beneficial effects of this invention are: 1. The ingenious structure of this invention enables the charging module housing, left and right handle assemblies, locking bracket assembly and cabinet to mutually limit and lock together, achieving convenient insertion, removal and assembly without the need for additional screws and tools.
[0016] 2. The present invention adopts a simple transmission lever structure, which makes it easy to insert and remove large-capacity multi-pin modules. With the help of the locking bracket assembly and spring, users can operate the left and right handles simultaneously with both hands. Only a small amount of operating force is needed to pull out and insert the charging module shell, which effectively solves the problem of difficult insertion and removal of heavy charging modules. It is suitable for operation by various people and significantly improves the user's convenience and experience.
[0017] 3. The locking bracket body of the present invention utilizes the advantage of easy forming of sheet metal to realize the movement space of the handle locking tongue and the top pin with very little material. The left and right handle components can be stored in the rectangular hole of the charging module housing, with only the handle head exposed, ensuring the simplicity of the overall appearance of the module. At the same time, after pushing the handle, the top pin will automatically push out the handle, which can easily pull the handle out of the module. The overall structure is compact and practical.
[0018] 4. This invention uses an arc-shaped hole on the handle and a hook at the tail to control the running trajectory of the left and right handles. The structure is simple and achieves an effective large-ratio lever effect, which greatly reduces the force required to insert and remove large-capacity modules. At the same time, it strictly controls the movement trajectory of the handle to achieve accurate and safe arrival at the ideal position for module insertion and removal. The spring is a high-strength spring with strong fatigue resistance, which avoids failure after long-term use and further extends the service life of the module. Attached Figure Description

Terms such as "upper," "lower," "left," and "right" are used only to indicate relative positional relationships; when the absolute position of the described object changes, the relative positional relationship may also change accordingly.
[0024] like Figure 1 As shown, a convenient charging module structure for a charging pile includes: a charging module housing 1 detachably mounted on a cabinet 6 along a linear direction. The charging module housing 1 is the main load-bearing body and structural frame of the entire module. It is a roughly rectangular box-shaped structure, and its interior is used to house electronic components such as charging circuits (not shown in the figure). A left handle assembly 4 and a right handle assembly 3 are symmetrically arranged on the charging module housing 1. A locking bracket assembly 2 adapted to the left handle assembly 4 and the right handle assembly 3 is also fixedly mounted on the charging module housing 1. The locking bracket assembly 2 is made of sheet metal. A stop pin 5 adapted to the left handle assembly 4 and the right handle assembly 3 is also provided on the cabinet 6. The stop pin 5, the charging module housing 1, the left handle assembly 4, the right handle assembly 3, and the locking bracket assembly 2 are mutually locked and limited to the cabinet 6.
[0025] The structure is an independent, pluggable functional module, mainly used in DC charging pile equipment. Its core innovation lies in the fact that the charging module housing 1 integrates a force-saving lever mechanism, an automatic locking and pop-out mechanism, so that the charging module housing 1 can be plugged in and fixed to the cabinet 6 in a force-saving, reliable and convenient manner without any additional tools.
[0026] like Figure 1 , Figure 6 and Figure 8 As shown, the cabinet 6 is provided with a receiving space for accommodating the charging module housing 1. Guide rail grooves 7 for guiding the insertion of the charging module housing 1 are fixedly installed on both sides of the receiving space. Multiple plug-in terminals 8 are fixedly installed on the bottom of the charging module housing 1. Multiple plug-in terminal blocks 9 that are adapted to the multiple plug-in terminals 8 are fixedly installed on the cabinet 6 for electrical connection when the charging module housing 1 is inserted into the position. The plug-in terminals 8 (such as multi-pin power and signal terminals) are installed at the bottom of the charging module housing 1. When the charging module housing 1 is fully pushed into the cabinet 6, the plug-in terminals 8 will accurately align with the plug-in terminal blocks 9 fixed on the cabinet 6 to realize the connection of power and signal.
[0027] like Figure 7 and Figure 8 As shown, slide rails 102 are fixedly installed on both sides of the charging module housing 1. The two slide rails 102 are slidably adapted to the two guide rail grooves 7 in the accommodating space. The bottom ends of the charging module housing 1 are provided with guide structures to guide the charging module housing 1 into the guide rail grooves 7. The guide structures are rounded chamfered structures with a radius of 5mm-10mm to reduce the resistance when the charging module housing 1 is inserted into the guide rail grooves 7, and at the same time avoid hard contact wear between the guide rail grooves 7 and the slide rails 102. A rectangular hole 103 is provided on one side of the top of the charging module housing 1 for the left handle assembly 4 and the right handle assembly 3 to pass through. The dimensions match the contours of the left handle assembly 4 and the right handle assembly 3, allowing for complete storage of the left handle assembly 4 and the right handle assembly 3 when not in operation, keeping the module's appearance flat and simple. A slide rail 102 is provided on each of the left and right sides of the charging module housing 1. These two slide rails 102 are key structures for connecting and guiding the charging module housing 1 to the cabinet 6 of the external charging pile. To facilitate insertion, the front end of each slide rail 102 is machined with a rounded chamfer to form a guiding structure. This rounded chamfer effectively guides the slide rail 102 to smoothly slide into the corresponding guide groove 7 inside the cabinet 6, avoiding jamming or wear caused by hard contact, and achieving quick and precise alignment and insertion.
[0028] like Figure 1 and Figure 2As shown, the locking bracket assembly 2 includes: a locking bracket body 201 fixedly installed at the top center of one side of the charging module housing 1; the top of the locking bracket body 201 is integrally formed with a stop strip 204 and a U-shaped bracket structure; both ends of the locking bracket body 201 are vertically inserted with top pins 205; a first spring 206 is fixedly installed between the top pins 205 and the locking bracket body 201; a retaining ring 207 is fixedly installed at the bottom end of the top pins 205, and the top pins 205 can rebound up and down through the limiting action of the retaining ring 207 and the cooperation of the first spring 206; a positioning pin 202 is fixedly inserted between the middle of the locking bracket body 201 and the charging module housing 1; rivets 203 are fixedly inserted between the two sides of the middle of the locking bracket body 201 and the charging module housing 1; the locking bracket assembly 2 is a locking and triggering mechanism integrated on the charging module housing 1, as shown in the figure. Figure 1 , Figure 2 As shown.
[0029] The main body of the locking bracket assembly 2 is a locking bracket body 201, which is integrally formed from a single sheet metal material through stamping and bending, resulting in a compact structure and high strength. The locking bracket body 201 is accurately fixed to the predetermined position on the charging module housing 1 by positioning pins 202 and rivets 203.
[0030] A stop bar 204 is formed by pressing upwards on the locking bracket body 201. The stop bar 204 is used to engage with the engaging parts (such as grooves or protrusions) on the left handle 401 and the right handle 301.
[0031] The top pin 205 is installed inside the locking bracket body 201 and can slide up and down along it. The ends of the two top pins 205 abut against the tail slopes or ends of the right handle 301 and the left handle 401, respectively. A first spring 206 is installed between the top pin 205 and the bottom of the locking bracket body 201 to provide an upward restoring force for the top pin 205. The bottom end of the top pin 205 is axially limited by a retaining spring 207 to prevent it from dislodging from the locking bracket body 201.
[0032] like Figure 1 , Figure 3 , Figure 4 , Figure 5 and Figure 8As shown, the left handle assembly 4 includes: a left handle 402 rotatably mounted on one top end of the charging module housing 1, and a left handle 401 slidably mounted in a square groove at one end of the left handle 402. The left handle 401 is adapted to the stop bar 204 and the U-shaped bracket structure for locking and limiting the left handle assembly 4 after it is retracted. The right handle assembly 3 includes: a right handle 302 rotatably mounted on the other top end of one side of the charging module housing 1, and a right handle 301 slidably mounted in a square groove at one end of the right handle 302. The right handle 301 is adapted to the stop bar 204 and the U-shaped bracket structure for locking and limiting the right handle assembly 3 after it is retracted; the two top pins 205 are respectively adapted to the left handle 401 and the right handle 301, and are used to push out the left handle assembly 4 and the right handle assembly 3 when the left handle 401 and the right handle 301 are pushed; wherein, when the left handle 401 and the right handle 301 are pushed and move away from each other, the left handle 401 and the right handle 301 disengage from the stop bar 204 and the U-shaped bracket structure, and the top pins 205 are activated by the first spring 206. The left and right handle assemblies 4 and 3 are automatically ejected, causing them to pop out of the rectangular hole 103 in the charging module housing 1 and into the operating position. When the left and right handle assemblies 4 and 3 are pushed into the rectangular hole 103 in the charging module housing 1, the slots of the left handle 401 and right handle 301 engage with the stop strip 204 on the locking bracket assembly 2. At the same time, the hook-shaped structures 501 on the left handle 402 and right handle 302 engage with the two stop pins 5 respectively, thus realizing the connection between the charging module housing 1 and the cabinet. The body 6 is locked in place. Both the left handle 402 and the right handle 302 have arc-shaped openings 504 for hand gripping. Hook-shaped structures 501 are provided at the center of the separated ends of both the left and right handles 402 and 302. These hook-shaped structures 501 are adapted to the stop pin 5 and work with the stop pin 5 to create a lever effect, providing assistance when inserting or removing the charging module housing 1. The left handle assembly 4 and the right handle assembly 3 are the core actuators for achieving effortless operation, and their structures are mirror-symmetrical. The following detailed description uses the left handle assembly 4 as an example; the right handle assembly 3 has the same structure.
[0033] like Figure 4 and Figure 5 As shown, the left handle assembly 4 mainly consists of two parts: the left handle 402 and the left grip 401. The left handle 402 is a lever arm with a specific profile. A square slot is provided at its upper part to accommodate the left grip 401. A central shaft hole 502 is provided in its middle part, through which a pivot 404 passes, rotatably hinges the entire left handle 402 to the charging module housing 1, allowing the left handle 402 to swing around the pivot 404. A large arc-shaped opening 504 is provided at its lower part for hand gripping, facilitating the operator's application of force.
[0034] Key Feature 1: Motion Trajectory Control: In addition to the arc-shaped opening 504, another precisely formed arc-shaped hole 503 is precisely formed on the left handlebar 402. The limiting pin 403 on the charging module housing 1 passes precisely through this arc-shaped hole 503. When the left handlebar 402 rotates around the pivot 404, the limiting pin 403 slides within the arc-shaped hole 503. The arc length and shape of the arc-shaped hole 503 strictly limit the maximum rotation angle of the left handlebar 402, thereby precisely controlling the handlebar's motion trajectory and ensuring that it safely and accurately reaches the predetermined operating position each time.
[0035] Key Feature Two: Effort-Saving Lever Structure: At the tail of the left handle 402, an inwardly curved hook-shaped structure 501 is machined. This hook-shaped structure 501 is the key to this invention. Figure 6 As shown, when the charging module housing 1 is inserted into the cabinet 6, the hook-shaped structure 501 will contact and engage with the stop pin 5 fixed on the cabinet 6. When the charging module housing 1 is pulled out, as the operator pulls the left handle 402 and the right handle 302 outward, the hook-shaped structure 501, with the stop pin 5 as the fulcrum, converts the weight of the charging module housing 1 and the insertion / removal resistance into torque. By utilizing the lever principle, the required manual operating force is greatly reduced.
[0036] The left handle 401 is slidably mounted in a square groove above the left handle 402. A pan head screw 405 is screwed into the bottom of the left handle 402, the head of which is larger than the opening at the bottom of the square groove, thus confining the left handle 401 within the square groove, allowing it to slide left and right along the groove without coming off upwards. A second spring 406 is provided in the mounting hole between the left handle 401 and the left handle 402. The two ends of the second spring 406 abut against the left handle 401 and the left handle 402 respectively, providing an elastic force for the left handle 401 to automatically return to its original position.
[0037] The right handle assembly 3 is constructed in exactly the same way as the left handle assembly 4, including the right handle 302, the right grip 301, and corresponding springs and other components, which will not be described in detail here.
[0038] like Figure 3 and Figure 8As shown, a pivot 404 is inserted between the left handle 402 and the charging module housing 1, and between the right handle 302 and the charging module housing 1. The pivot 404 is used to limit the rotation center of the left handle 402 and the right handle 302 on the charging module housing 1. Two limiting pins 403 are fixedly installed on the charging module housing 1. Both the left handle 402 and the right handle 302 have arc-shaped holes 503 adapted to the limiting pins 403. Both the left handle 402 and the right handle 302 have central shaft holes 502 for the pivot 404 to pass through. Pan head screws 405 are threaded into the bottom of the left handle 401 and the bottom of the right handle 301. The two pan head screws 405 are slidably connected to the left handle 402 and the right handle 302 respectively. A second spring 406 is embedded in the inner groove between the left handle 401 and the left handle 402, and in the inner groove between the right handle 301 and the right handle 302.
[0039] The working principle and operation process of this invention are as follows: a) The module retrieval process: Initial state (locked and stored state): as follows Figure 7 As shown, the charging module housing 1 is installed inside the cabinet 6. The left handle assembly 4 and the right handle assembly 3 are completely retracted into the rectangular hole 103 of the charging module housing 1, with only the heads of the left handle 401 and the right handle 301 exposed. At this time, the left handle 401 and the right handle 301 are in the outward position under the action of their respective second springs 406, and their engaging parts engage with the stop strip 204 on the locking bracket assembly 2, locking the left handle assembly 4 and the right handle assembly 3 in the retracted position. At the same time, the hook-shaped structure 501 of the left handle assembly 4 and the right handle assembly 3 also engages with the stop pin 5, locking the charging module housing 1 in the cabinet 6.
[0040] Unlocking and ejection: The operator uses both thumbs to simultaneously push the exposed left handle 401 and right handle 301 inwards. The left handle 401 and right handle 301 slide inwards, first disengaging their locking parts from the stop bar 204, releasing the internal lock. As the left handle 401 and right handle 301 continue to move inwards, their tail slopes push the top pin 205 downwards, overcoming the elastic force of the first spring 206.
[0041] Preparation: After the top pin 205 is pressed down a certain distance, the contact relationship between its end and the left handle 402 and the right handle 302 changes. Under the strong restoring force of the first spring 206, the top pin 205 quickly rebounds upward, impacting and pushing the left handle assembly 4 and the right handle assembly 3, causing them to rotate outward around the pivot 404, thereby automatically popping out from the rectangular hole 103. Figure 1 The prepared operation position is shown.
[0042] Effortless Pull-out: The operator holds the arc-shaped openings 504 on the left handle assembly 4 and the right handle assembly 3 with both hands and applies outward pulling force. At this time, the hook-shaped structures 501 at the tail of the left handle assembly 4 and the right handle assembly 3 form a force-saving lever with the stop pin 5 as the fulcrum. Only a small force is needed to smoothly pull the heavy charging module housing 1 out of the guide rail groove 7 until the plug-in terminal 8 separates from the plug-in terminal base 9.
[0043] b) Module insertion and locking process: Alignment and Insertion: Hold the pop-out left handle assembly 4 and right handle assembly 3 with both hands, align the plug-in terminal 8 at the bottom of the charging module housing 1 with the plug-in terminal block 9 on the cabinet 6, and at the same time align the slide rails 102 on both sides of the charging module housing 1 with the guide rail groove 7. With the help of the rounded chamfer at the end of the slide rail 102, push the charging module housing 1 smoothly into the cabinet 6.
[0044] Push-in locking: When the charging module housing 1 is nearly fully inserted, the hook-shaped structures 501 of the left handle assembly 4 and the right handle assembly 3 will contact and pass over the stop pin 5. Continue pushing the charging module housing 1 inward, and then press the left handle assembly 4 and the right handle assembly 3 towards the charging module housing 1 by hand, so that they rotate back into the rectangular hole 103. During this process, the left handle 401 and the right handle 301 will be briefly squeezed in when they contact the stop bar 204. After the left handle assembly 4 and the right handle assembly 3 are fully retracted, their engaging parts will spring back under the action of the second spring 406, locking with the stop bar 204 with a "click". At the same time, the hook-shaped structures 501 of the left handle assembly 4 and the right handle assembly 3 will also re-engage with the stop pin 5.
[0045] Fixing complete: At this point, the charging module housing 1 is firmly and reliably fixed inside the cabinet 6 through a double locking mechanism of internal (left handle 401, right handle 301-stop bar 204) and external (hook structure 501-stop pin 5), effectively preventing accidental loosening due to vibration or accidental contact.
[0046] In summary, this invention, through its ingeniously integrated mechanical structure, perfectly solves the technical problems of difficult insertion and removal and inconvenient operation of heavy-duty charging modules. The entire solution is compact, reliable in operation, and requires no additional tools, greatly improving user experience and equipment maintenance efficiency.
