DETAILED DESCRIPTION
[0022] In order to better understand the utility model, the content of the utility model is further illustrated below in combination with examples, but the content of the utility model is not limited to the following examples.
[0023] like Figure 1 As shown, a DC charger that uses multiple charging modules has a charging pile 1 with an internal storage cavity 102. The charging module 4 can be securely placed in the storage cavity 102 and precisely connected to the docking seat 101 set on the inner wall of the storage cavity 102 in the depth direction, thereby laying a solid foundation for the stable and efficient transmission of electrical energy.
[0024] An ingeniously designed support component 7 is installed within the storage cavity 102. This support component 7 fits snugly with multiple guide components 5, forming an organic whole. Each guide component 5 is connected to a charging module, and they work together in concert. Figure 1 As shown, with the strong assistance of the guide member 5, the carrier member 7 can easily separate multiple charging modules from their corresponding docking seats 101. In this way, the multiple charging modules, with the cooperation of the bottom surface of the storage cavity 102, can be accurately and horizontally positioned at a lower position. This eliminates the need for laborious lifting operations or cumbersome procedures when inspecting, maintaining, or replacing the charging modules, greatly improving the convenience of the work. Meanwhile, as... Figure 4 As shown, the carrier 7 can also help multiple charging modules to be quickly connected to the corresponding docking seat 101 at the same time, enabling staff to quickly and conveniently achieve electrical connection between the charging module 4 and the charging pile 1, which significantly improves work efficiency.
[0025] like Figure 1 and Figure 4 As shown, from a structural perspective, the support component 7 includes a central column 701 firmly fixed within the storage cavity 102, providing a solid and reliable support foundation for other components. The central column 701 is rotatably connected to a flip plate 702, which has a specially designed placement slot 703. This ingenious design provides just the right space for placing the charging module 4. Multiple translation frames 704 are neatly arranged on the two side walls of the placement slot 703, with two sets of translation frames 704 corresponding one-to-one, forming a rigorous and orderly layout. Between the corresponding two translation frames 704, a driving component is installed, which includes a snap-fit cylinder 501 for connecting to the charging module 4. Rotating columns 502 are firmly mounted on both sides of the snap-fit cylinder 501. These rotating columns 502 play a crucial connecting and transmission role in the entire structural system, serving as an important hub for the coordinated operation of all components.
[0026] like Figure 1As shown, when the charging module 4 needs to be inspected and maintained, the operator only needs to gently pull the flip plate 702 to flip it. At this time, driven by the flip plate 702, and with the help of the pulling action of the translation frame 704 on the rotating column 502, the locking cylinder 501 and the charging module 4 locked inside the locking cylinder 501 can be smoothly pulled out together. Subsequently, the flip plate 702 is stably placed horizontally with the support of the bottom surface of the storage cavity 102, and the multiple charging modules 4 are also arranged horizontally in sequence, presenting themselves to the operator in an orderly manner. This unique design allows the operator to clearly observe and conveniently operate each charging module 4, greatly facilitating the smooth progress of inspection and maintenance work. Figure 4 As shown, it is particularly worth mentioning that the inner wall of the card holder 501 adopts a horn-shaped design, with the narrow opening of the horn facing the storage cavity 102. The horn-shaped design is not only aesthetically pleasing, but more importantly, it can effectively reduce the difficulty for operators to insert or pull out the charging module 4, and adapt to the slight deformation of the surface of the charging module 4 so that the charging module 4 is firmly locked together with the card holder 501, thereby making the positioning, connection or replacement process of the charging module 4 easier and faster.
[0027] like Figure 1 and Figure 2 As shown, there is a rotating post 502 on each side of the snap-fit cylinder 501. They pass through two corresponding translation frames 704 and are firmly fixedly connected to the guide block 503. These guide blocks 503 play a crucial role in the installation and positioning of the charging module 4. After completing the inspection, maintenance, or replacement of the charging module 4, the operator can push the flip plate 702 to reset it. At this time, the guide block 503 can precisely engage with the guide rails 504 fixed on both sides of the storage cavity 102 in the width direction. The guide rail 504 consists of two parts: an entry part 5041 and a docking part 5042. The entry part 5041 adopts an arc track design with the central post 701 as the center to ensure that the guide block 503 enters the entry part 5041 stably and smoothly under the drive of the flip plate 702, and smoothly transitions into the docking part 5042 as the flip plate 702 continues to flip. The docking part 5042 is a horizontally set track that precisely corresponds to the docking seat 101. It effectively assists the charging module 4 in accurately aligning with the docking seat 101, making full preparations for subsequent installation and electrical connection operations. When the guide block 503 enters the guide rail 504, it will slide flexibly within the translation frame 704, so that the interface on the charging module 4 set in the snap-fit cylinder 501 is precisely aligned with the docking seat 101. This greatly facilitates the subsequent connection of the charging module 4 with the docking seat 101 and the completion of the electrical connection process.
[0028] To further enhance the stability and reliability of the charging module 4 connection, a top-pressure slider 706 is slidably installed within the translation frame 704. The top-pressure slider 706 adopts an I-shaped design, a clever design that effectively ensures its stability when sliding within the translation frame 704, preventing wobbling or misalignment. A top-pressure spring 705 is installed between the top-pressure slider 706 and the inner wall of the translation frame 704 on the side away from the storage cavity 102, tightly connecting the two. When the guide block 503 adjusts the charging module 4 to the corresponding position with the docking seat 101 via the rotating column 502 and the locking cylinder 501, the top-pressure spring 705 fully utilizes its elasticity to forcefully push the charging module 4 to electrically connect with the docking seat 101, ensuring a tight and stable connection. Meanwhile, when the flip plate 702 flips to place multiple charging modules 4 horizontally in sequence for easy inspection, the top pressure spring 705 can also provide good buffering for the charging modules 4, effectively reducing the probability of damage to the charging modules 4 due to collision or vibration, thereby significantly extending the service life of the charging modules 4.
[0029] like Figure 1 and Figure 4 As shown, a positioning element 3 is fixedly installed at the top interior of the storage cavity 102 in the depth direction. This positioning element 3 consists of two connecting plates 303 fixed to the inner wall of the storage cavity 102, each with a C-shaped engaging portion 302. This engaging portion 302 can tightly engage with the engaging post 304 located at the end of the flip plate 702 opposite to the central post 701. When the charging module 4 docks with the docking seat 101, the positioning element 3 precisely assists in positioning the flip plate 702, thereby accurately locking the position of the charging module 4 and ensuring accurate connection between the charging module 4 and the docking seat 101. In order to enable the snap-fit pin 304 to enter the snap-fit part 302 more smoothly and be firmly positioned, the connecting plate 303 is specially designed with a chamfer 301 at the notch of the snap-fit part 302. The ingenious design of the chamfer 301 can effectively guide the snap-fit pin 304 to enter the snap-fit part 302 smoothly, greatly improving the efficiency and accuracy of positioning.
[0030] like Figure 1 As shown, a reinforcement member 6 is also provided between the storage cavity 102 and the flip plate 702, the main function of which is to help maintain the horizontal state of the flip plate 702. The reinforcement member 6 includes a reinforcement platform 603 fixedly installed on the inner wall of the storage cavity 102 in the width direction and a support column 601 on the flip plate 702. The end of the support column 601 is tightly connected to the reinforcement platform 603 of the through groove by a support rope 602. When the flip plate 702 is in a horizontal state, the reinforcement member 6 can significantly enhance the structural stability of the flip plate 702, effectively preventing it from shaking or tilting, thereby creating a more stable and reliable environment for the inspection, maintenance and installation of the charging module 4.
[0031] like Figure 1 and Figure 3 As shown, a protective door 2 is rotatably connected to the outer edge of the storage cavity 102 via a hinge. The protective door 2 is equipped with a lock, which can be used to seal the storage cavity 102 as needed, effectively preventing the charging module 4 from being lost; it can also be easily opened to expose the interior of the storage cavity 102. Meanwhile, ventilation holes are specially provided on the protective door 2, a design that ensures the charging module 4 is always in a well-ventilated environment, effectively reducing the probability of a decrease in operating speed due to overheating of the charging module 4. Additionally, a push handle 8 is provided on the side of the flip plate 702 away from the storage cavity 102. This push handle 8 is located at the center of the flip plate 702, making it convenient for operators to grip and easily drive the flip plate 702 to flip or place, greatly improving operational convenience.
[0032] The specific embodiments of this utility model have been described above. It should be understood that this utility model is not limited to the specific embodiments described above, and those skilled in the art can make various modifications or variations within the scope of the claims, which do not affect the substantive content of this utility model.
