[0033] Refer to the appendix Figure 1 - appendix Figure 7 , a window installation structure for an automobile charging box, including a box body 1 and a pressing plate 2; a receiving cavity 10 for installing a control unit 3 is provided inside the box body 1, a storage cavity 100 is provided on the side wall of the receiving cavity 10, a notch 101 and a window 102 are respectively provided on both sides of the storage cavity 100, the notch 101 communicates with the receiving cavity 10, the window 102 communicates with the outside and corresponds to the display screen 30 of the control unit 3, and a plurality of struts 103 surrounding the window 102 are further provided on the top wall of the storage cavity 100; a transparent observation block 21 is provided on the pressing plate 2, a plurality of fixing blocks 22 are installed around the periphery of the observation block 21, and fastening bolts 23 are provided on all the fixing blocks 22; wherein, the pressing plate 2 can enter the storage cavity 100 through the notch 101, and when the bottom surface of the pressing plate 2 is closely attached to the top wall of the storage cavity 100, the observation block 21 is inserted into the window 102 to align with the display screen 30, the plurality of fixing blocks 22 are respectively abutted against the plurality of struts 103, and the fastening bolts 23 are threadedly connected to the struts 103 to lock the pressing plate 2 in the storage cavity 100.

[0034] Specifically, during use, the user can view the data information on the display screen 30 through the observation block 21, and then operate the control unit 3 of the charging box to adjust the output voltage / current to adapt to the user's own vehicle model.

[0035] Among them, since the observation block 21 is inserted into the window 102 and the fixing blocks 22 on the pressing plate 2 are fixed on the struts 103 through the fastening bolts 23, it is convenient to disassemble and assemble the pressing plate 2 and the observation block 21; at the same time, this installation method can make the bottom surface of the pressing plate 2 closely attached to the top wall of the storage cavity 100 to reduce the gap between the pressing plate 2 and the box body 1, ensure that the periphery of the observation block 21 has uniform supporting force, and when the box body 1 is impacted, the observation block 21 can evenly transfer the pressure to the pressing plate 2 and each strut 103 to prevent the observation block 21 from shaking due to the impact.

[0036] In summary, in the present utility model, a storage cavity 100 is designed on the side wall of the accommodating cavity 10 of the box body 1 for placing the pressing plate 2, so that the observation block 21 can be inserted into the window 102 and correspond to the display screen 30. By designing a fastening bolt 23 on the fixing block 22 on the peripheral side of the pressing plate 2 for threaded connection with the pillar 103 on the peripheral side of the window 102, it is not only convenient for the disassembly and assembly of the pressing plate 2 and the observation block 21, but also can make the force on the peripheral side of the pressing plate 2 uniform, thereby improving the impact resistance of the observation block 21.

[0037] Refer to the attached Figure 1 - attached Figure 7 , the pressing plate 2 has the same shape as the storage cavity 100, making the two perfectly adapted; this design ensures that when the pressing plate 2 is located in the storage cavity 100, it will not shift forward, backward, left, or right, further restricting the movement of the observation block 21 and improving the installation stability of the observation block 21.

[0038] Refer to the attached Figure 1 - attached Figure 7 , a sleeve hole 220 is provided on the fixing block 22. When the bottom surface of the pressing plate 2 is closely attached to the top wall of the storage cavity 100, the sleeve hole 220 sleeves the pillar 103; one end of the fastening bolt 23 abuts against the fixing block 22, and the other end of the fastening bolt 23 extends into the sleeve hole 220 and is threadedly connected to the pillar 103.

[0039] Specifically, the matching design of the sleeve hole 220 and the pillar 103 enables the pressing plate 2 to directly transfer the pressure to the pillar 103 through the fixing block 22 when the pressing plate 2 is under pressure, reducing the possibility of damage to the fastening bolt 23; at the same time, this design can also prevent the pressing plate 2 from shifting forward, backward, left, or right, further improving the installation stability of the pressing plate 2 and the observation block 21.

[0040] Refer to the attached Figure 1 - attached Figure 7 , a plurality of avoidance openings 104 are connected to the side wall of the storage cavity 100. The plurality of avoidance openings 104 are designed corresponding to the plurality of pillars 103 one by one. When the sleeve hole 220 sleeves the pillar 103, the fixing block 22 is inserted into the avoidance opening 104.

[0041] Specifically, the plurality of avoidance openings 104 enable the fixing block 22 to enter the storage cavity 100 and be supported by the side wall of the storage cavity 100, so that the pressure received by the pressing plate 2 can be directly transferred to the box body 1, further improving the impact resistance of the pressing plate 2 and the observation block 21.

[0042] Refer to the attached Figure 1 - attached Figure 7 , an annular clamping groove 10c surrounding the window 102 is further provided on the top wall of the storage cavity 100, and an annular clamping block 2c is provided on the bottom surface of the pressing plate 2. When the bottom surface of the pressing plate 2 is closely attached to the top wall of the storage cavity 100, the annular clamping block 2c is inserted into the annular clamping groove 10c.

[0043] Specifically, the cooperation between the annular clamping block 2c and the annular clamping groove 10c can serve as the first layer of protection for the box body 1, initially eliminating the gap between the bottom surface of the pressing plate 2 and the top wall of the storage cavity 100, having a certain waterproof and dustproof effect, and preventing water from entering the box body 1 through the window 102.

[0044] Refer to the appendix Figure 1 - appendix Figure 7 Moreover, an annular sealing ring 10f surrounding the window 102 is also provided on the top wall of the storage cavity 100. When the bottom surface of the pressing plate 2 closely adheres to the top wall of the storage cavity 100, the bottom surface of the pressing plate 2 presses the annular sealing ring 10f, causing the annular sealing ring 10f to undergo adaptive deformation.

[0045] Specifically, the design of the annular sealing ring 10f can serve as the second layer of protection for the box body 1, further eliminating the gap between the bottom surface of the pressing plate 2 and the top wall of the storage cavity 100, having a better waterproof and dustproof effect, and comprehensively preventing dust and water from entering the box body 1 through the window 102.

[0046] Refer to the appendix Figure 1 - appendix Figure 7 Both the box body 1 and the pressing plate 2 are made of hard materials, and the pressing plate 2 and the observation block 21 are integrally formed.

[0047] Specifically, after charging is completed, the charging box is usually directly placed on the ground by the user, making it vulnerable to being run over by a car. Therefore, making the charging box of hard material can improve its compressive resistance and reduce the possibility of the charging box cracking; while the integral formation of the pressing plate 2 and the observation block 21 is convenient for mold manufacturing on the one hand and can improve the impact resistance of the pressing plate 2 and the observation block 21 on the other hand, preventing them from cracking due to being run over.

[0048] Among them, there are various types of hard materials, such as polyethylene, polypropylene, polyvinyl chloride, polytetrafluoroethylene, 3ET, ABS, plexiglass, etc. Among them, 3ET, ABS, plexiglass, etc. also belong to transparent materials and can be used as the preparation materials for the pressing plate 2 and the observation block 21.

[0049] Refer to the appendix Figure 1 - appendix Figure 7 The box body 1 includes a bottom shell 11 and a top cover 12. The top cover 12 is detachably covered on the bottom shell 11 and encloses to form an accommodation cavity 10. The storage cavity 100 is arranged on the top cover 12; the cooperative design of the bottom shell 11 and the top cover 12 enables the accommodation cavity 10 to be opened, facilitating the disassembly, assembly, and maintenance of the control unit 3 and the pressing plate 2.

[0050] Refer to the appendix Figure 1 - appendix Figure 7, it is observed that the outer wall of the observation block 21 and the outer wall of the top cover 12 are on the same arc surface. This design can make the surface of the box body 1 smooth. On the one hand, it can improve the holding feel and overall aesthetics. On the other hand, it can prevent the observation block 21 from protruding from the window 102 and bumping the user.

[0051] It should also be noted that although the embodiments of the present application have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present application.
