However, when other models of charging modules are needed, the different dimensions of each module necessitate a redesign of the charger casing. This results in low compatibility between chargers and other charging modules, and high development costs for manufacturers. For charging station operators, if chargers are incompatible with multiple charging modules, users will face compatibility issues, reducing the user experience. Utility Model Content

[0004] This utility model provides a quick-change slot for the charging module of a commercial vehicle charger to solve the problem of low compatibility of commercial vehicle chargers with various models of charging modules.

[0005] To address the aforementioned issues, this utility model provides a quick-change slot for a charging module in a commercial vehicle charger. This quick-change slot is used to install a charging module and includes a partition plate, several guide plates on one side of the partition plate, a left upright plate vertically mounted on the left side of the partition plate, a right upright plate vertically mounted on the right side of the partition plate, a fixing plate vertically mounted in front of the partition plate, a grid plate perpendicular to the rear of the partition plate, and a tail plug fixed to the upper right of the grid plate. Through this solution, the modular frame design of the partition plate, left and right upright plates, and grid plate can accommodate charging modules of different sizes and interfaces, supports flexible adjustment of spacing and limits, guide plates guide precise installation, and the open frame structure facilitates disassembly and assembly, reducing operation time.

[0006] According to one embodiment of the present invention, the aforementioned spacer plate is provided with a plurality of rectangular slots. The slots work together with the guide plate to ensure accurate alignment when the charging module is inserted, thereby reducing interface wear or poor contact caused by installation misalignment.

[0007] According to one embodiment of the present invention, the slot is located on the right side of the guide plate, allowing the operator to insert and remove the module in a single direction along the right side without frequently adjusting their position, thus reducing the complexity of operation in a confined space.

[0008] According to one embodiment of the present invention, the charging module is provided with adjustable wedge blocks at both the top and bottom.

[0009] According to one embodiment of the present invention, the upper part of the wedge block is a double trapezoidal inclined surface. When the charging module is inserted into the quick-change slot, the trapezoidal wedge block can be adjusted up and down according to the space size of the slot, thereby adapting to the size differences of different models of charging modules and improving the compatibility of the quick-change slot with different models of charging modules.

[0010] According to one embodiment of the present invention, a plurality of springs are fixed to the bottom of the wedge-shaped block.

[0011] According to one embodiment of the present invention, the partition plate, left upright plate, right upright plate and grid plate are all fixedly installed by bolts. The above solution facilitates the disassembly and replacement of each component. When a component is damaged, it can be repaired or replaced in a timely manner, thus reducing maintenance costs.

[0012] According to one embodiment of the present invention, the top and bottom ends of the front facade of the charging module are provided with threaded mounting holes. Through the above solution, screws and other connecting parts for installing and fixing the charging module are provided, which further enhances the stability of the charging module in the quick-change slot and ensures the safety and reliability of the charging process.

[0013] According to one embodiment of the present invention, the periphery of the spacer plate at the top and bottom of the quick-change slot is bent. This solution increases the strength and rigidity of the spacer plate, prevents deformation of the spacer plate during use, and thus ensures the overall structural stability of the quick-change slot.

[0014] According to one embodiment of the present invention, the grid plate is provided with fixing corner pieces at the two opposite corners at the bottom. Through the above solution, the grid plate is firmly fixed in the corresponding position of the charger, preventing the grid plate from shaking or shifting, and ensuring the connection stability between the charging module and components such as the tail plug.

[0015] The technical advantages of this application are as follows:

[0016] 1. The quick-change slot for the charging module of a commercial vehicle charger provided in this application is a sheet metal bending part. Different series of chargers can be adapted to different models of charging modules by adjusting the height of the upright plate and the gap of the guide plate, so as to realize the serialized application of chargers.

[0017] 2. The charging module is guided into the slot by a guide plate and then locked in place by screws, making it convenient and reliable.

[0018] 3. The grid plate is equipped with a charging module connector. After the charging module is inserted in the correct orientation, it can be slid directly into the connector and then the screws can be tightened for a secure installation. If inserted in the wrong orientation, the wedge-shaped block of the charging module will not be able to slide into the bottom of the slot, thus eliminating the possibility of misinstallation. To remove the charging module, simply unscrew the fixing screws and pull the charging module outward to detach it from the slot.

[0019] 4. This quick-change slot allows the charging module to be neatly installed inside the charger. Labels can be affixed to the corresponding positions, making the appearance aesthetically pleasing and easy to manage and distinguish. Attached Figure Description

[0026] The following will be combined with the appendix Figures 1-3 The embodiments of the technical solution of this application are described in detail below. The following embodiments are only used to illustrate the technical solution of this application more clearly, and are therefore only examples and should not be used to limit the scope of protection of this application.

[0027] Reference Figure 1-3This utility model provides a quick-change slot for a charging module of a commercial vehicle charger. In this embodiment, the quick-change slot is used to install a charging module 1000. The quick-change slot includes a partition plate 1. Six parallel guide plates 4 are provided on the upper or lower side of the partition plate 1. The guide plates 4 are made of high-strength spring steel and have an anti-rust coating. A left upright plate 2 is vertically fixed to the left side of the partition plate 1, a right upright plate 7 is vertically fixed to the right side, a fixed plate 3 is vertically installed in front, and a grid plate 8 is vertically installed in the rear. A tail plug 9 is fixed to the upper right part of the grid plate 8. The tail plug 9 adopts an aviation plug design to ensure reliable electrical connection.

[0028] The partition plate 1 has 6 sets of rectangular slots 5, which are located to the right of the guide plate 4. The slot width is adapted to the wedge blocks 10001 on the charging modules 1000 of different specifications. The charging module 1000 has a set of adjustable wedge blocks 10001 and a groove to accommodate the contraction of the wedge blocks 10001 on both the upper and lower sides. The upper part of the wedge block 10001 is a double trapezoidal slope, and the two sides form inclined surfaces. Two springs 10002 are fixedly installed at the bottom. The other end of the spring 10002 is fixedly installed in the groove. By designing different spring stiffness and trapezoidal angle, it can adapt to the size of various wedge blocks 10001.

[0029] When the charging module 1000 is inserted into the quick-change slot, the inner wall of the spacer 1 contacts the inclined surface of the wedge block 10001. The spacer 1 applies a lateral force to the wedge block 10001, compressing the spring 10002 and causing the wedge block 10001 to contract vertically downwards. As the wedge block 10001 gradually contacts the slot 5, the pressure of the spacer 1 gradually decreases. Due to the rebound force of the spring 10002, the wedge block 10001 is adjusted upwards and pushed into the slot, forming a friction locking effect to prevent loosening. When the charging module 1000 is pulled out of the quick-change slot, the inclined surface on the other side of the trapezoidal wedge block 10001 is pressed by the spacer 1, causing the wedge block 10001 to retract back into the groove, thus allowing the charging module 1000 to be easily pulled out.

[0030] The partition plate 1, left upright plate 2, right upright plate 7, and grid plate 8 are all fixedly installed using M6 bolts. The bolt holes are equipped with anti-loosening adhesive. This bolt-fixing method facilitates the disassembly and replacement of partition plate 1 or grid plate 8. When these components are damaged, they can be repaired or replaced promptly, reducing maintenance costs. The charging module 1000 has two threaded mounting holes at the top and bottom of its front facade, which are secured to the fixing plate 3 with screws. These threaded mounting holes are used to install screws and other connecting parts to fix the charging module 1000, further enhancing the stability of the charging module 1000 within the quick-change slot and ensuring a safe and reliable charging process.

[0031] The partition plates 1 located at the top and bottom of the quick-change slot have inwardly bent edges. This bent design increases the strength and rigidity of the partition plates 1, preventing deformation of the outer partition plates 1 during use and ensuring the overall structural stability of the quick-change slot. L-shaped fixing brackets 6 are located at the two opposite corners of the bottom of the grid plate 8. These fixing brackets 6 secure the quick-change slot to the charger, preventing it from shaking or shifting and ensuring the connection stability between the charging module 1000 and components such as the tail plug 9.

[0032] The partition plate 1 is made of aluminum-zinc coated steel sheet and has screw holes at its connections with the left upright plate 2, right upright plate 7, and grid plate 8. The right upright plate 7 and left upright plate 2 are also made of aluminum-zinc coated steel sheet, with bent edges on all four sides to increase support strength, and have screw holes at their connections with other plates. The fixing plate 3 is made of aluminum-zinc coated steel sheet and has screw holes for fixing the charging module 1000 and for fixing it to the charger housing. The grid plate 8 is made of aluminum-zinc coated steel sheet and has ventilation holes; the tail plug 9 is fixedly installed on the grid plate 8 in a predetermined direction. The fixing corner piece 6 is made of aluminum-zinc coated steel sheet and has screw holes for locking it to the charger housing.

[0033] Working principle:

[0034] Secure the partition plate 1 vertically to the right upright plate 7, and then secure the left upright plate 2 vertically to the left side of the partition plate 1. Install the fixing plate 3 in front of the partition plate 1 and secure it to both the right upright plate 7 and the left upright plate 2. Fix the tail plug 9 to the upper right of the grid plate 8 in the correct direction. Secure the grid plate 8 to the rear of the partition plate 1. Install the fixing corner piece 6 at the lower part of the grid plate 8. After the quick-change slot is assembled, it is locked to the charger housing by the screw holes on the fixing plate 3 and the fixing corner piece 6. Finally, slide the charging module 1000 into the quick-change slot along the guide piece 4 on the partition plate 1. Slide the wedge block 10001 into the slot 5. Insert the tail plug 9 into the rear of the charging module 1000 in the correct direction to complete the installation.
