[0031] The following further describes the present utility model with reference to the accompanying drawings and specific embodiments.

[0032] Please refer to Figures 1-6 As shown, an integrated electric vehicle charging device includes:

[0033] A box body, which is composed of a bracket 1 and cover plates 2 detachably connected to the upper and lower sides of the bracket 1;

[0034] An electrical connector 3 is provided on the surface of the box body, and electrical components are provided inside. The electrical connector 3 is used for electrically connecting to the internal electrical components;

[0035] The bracket 1 forms a first accommodation cavity 1.2 and a second accommodation cavity 1.3 that are separated up and down through a spacer 1.1,

[0036] The electrical components include a PDU module 4 and a buck-boost module 5. The PDU module 4 is assembled in the first accommodation cavity 1.2, and the buck-boost module 5 is arranged in the second accommodation cavity 1.3.

[0037] After adopting the above structure, compared with the prior art, the integrated electric vehicle charging device of the present utility model has the following advantages: The bracket 1 forms a first accommodation cavity 1.2 and a second accommodation cavity 1.3 that are separated up and down through a spacer 1.1, and the PDU module 4 is assembled in the first accommodation cavity 1.2 to be responsible for power distribution and management;

[0038] The buck-boost module 5 is assembled in the second accommodation cavity 1.3 for voltage adjustment;

[0039] The electrical connector 3 can be electrically connected to the PDU module 4 and the buck-boost module 5;

[0040] The spacer 1.1 realizes the physical separation of the PDU module 4 and the buck-boost module 5, reduces the interference between them, and improves the operation reliability.

[0041] At the upper and lower parts of the bracket 1, the cover plates 2 can be respectively connected to cover the openings of the first accommodating cavity 1.2 and the second accommodating cavity 1.3, so as to form an integrated and relatively enclosed box structure, improve the safety performance, reduce the material contact, and extend the service life.

[0042] This device also has the characteristics of reasonable, compact structure layout, small space occupation, and is suitable for installation on cars with limited space. In addition, the detachable upper and lower cover plates 2 are convenient for maintaining and replacing internal components.

[0043] As an improvement of the utility model, the middle area at the bottom of the spacer 1.1 is recessed upward, so as to increase the accommodating space in the middle area of the second accommodating cavity 1.3.

[0044] The buck-boost module 5 includes a first main control component 5.1 and an inductor component 5.2 electrically connected to the first main control component 5.1. The first main control component 5.1 and the inductor component 5.2 are arranged in the middle area of the second accommodating cavity 1.3 in a front-back arrangement.

[0045] The middle area at the bottom of the spacer 1.1 is recessed upward, increasing the internal space in the middle area of the second accommodating cavity 1.3. Thus, it can accommodate the relatively large first main control component 5.1 and the inductor component 5.2. And the first main control component 5.1 and the inductor component 5.2 are arranged in a front-back arrangement, which is more reasonable in structure layout and has higher space utilization rate.

[0046] As an improvement of the utility model, the spacer 1.1 with the middle area recessed upward divides the first accommodating cavity 1.2 into a first chamber and a second chamber separated left and right.

[0047] The PDU module 4 includes a relay unit 4.1 and a fuse 4.2. The relay unit 4.1 is arranged in the first chamber, and the fuse 4.2 is arranged in the second chamber. The relay unit 4.1 is electrically connected to the insulating seat through a copper bar 6, and the copper bar 6 crosses the upward recessed part of the spacer 1.1.

[0048] The relay unit 4.1 and the fuse 4.2 have more wiring requirements respectively. Therefore, they are respectively assembled in the left and right separated first chamber and second chamber, which can isolate the two in the first accommodating cavity 1.2, avoid the interference between them, and improve the safety.

[0049] Only large current is transmitted between the relay unit 4.1 and the fuse 4.2 through the copper busbar 6, reducing connection complexity and failure points;

[0050] The structural layout is further optimized to make the maintenance and replacement of components more convenient, especially for the independent maintenance of the relay unit 4.1 and the fuse 4.2.

[0051] As an improvement of the present utility model, the step-up / step-down module 5 further includes a DCDC unit 5.3 disposed on the right side of the second accommodating cavity 1.3. After the above improvement, the compactness of the structural layout is further improved.

[0052] As an improvement of the present utility model, the spacer 1.1 is provided with a heat exchange flow channel 1.11 extending circuitously, and the bracket 1 is further provided with a liquid inlet 1.111 and a liquid outlet 1.112 communicating with the heat exchange flow channel 1.11. The heat exchange flow channel 1.11 is provided on the spacer 1.1, and the liquid inlet 1.111 and the liquid outlet 1.112 communicating with the heat exchange flow channel 1.11 are provided on the bracket 1. The heat dissipation medium enters through the liquid inlet 1.111, passes through the heat exchange flow channel 1.11, and finally discharges from the liquid outlet 1.112, which can take away the heat generated by the electrical components, improve the heat dissipation performance, and make the device operate stably and reliably with a long service life.

[0053] As an improvement of the present utility model, the bracket 1 and the spacer 1.1 are integrally formed. The bracket 1 and the spacer 1.1 are a whole, without splicing or welding points, ensuring the integrity and uniformity of the structure, which is beneficial to production and manufacturing.

[0054] As an improvement of the present utility model, mounting holes are provided on the peripheral side of the bracket 1, and the electrical connector 3 is assembled in the mounting holes. Mounting holes are provided on the peripheral side of the bracket 1, and the electrical connector 3 is directly assembled in the mounting holes of the bracket 1 to form an integral body with the bracket 1. The design of the mounting holes makes the installation and replacement process of the electrical connector 3 more simple and fast, and the mounting holes stably support the electrical connector 3, making it stable and reliable, which is beneficial to the assembly and disassembly of external plug-in components.

[0055] The above is only the preferred embodiment of the present utility model, and the protection scope of the present utility model is not limited to the above embodiments. All technical solutions falling within the idea of the present utility model belong to the protection scope of the present utility model. It should be noted that for those of ordinary skill in the art in this technical field, several improvements and retouches made without departing from the principle of the present utility model should also be regarded as the protection scope of the present utility model.
