Detailed implementation manners
[0018] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.
[0019] Please refer to Figures 1-3 , the present invention discloses a vehicle-mounted inverter provided with a leakage protection structure, including a housing 1. The left and right side surfaces of the housing 1 are open structures. A cooling mechanism 2 is arranged on the upper surface of the housing 1. A first sealing box 4 is installed on the right side surface of the housing 1 through a first locking bolt 3. A second sealing box 6 is installed on the left side surface of the housing 1 through a second locking bolt 5. A buffer mechanism 7 is installed on the side surfaces of the first sealing box 4 and the second sealing box 6 facing each other. An inverter assembly 8 and a leakage protector 9 are installed on the buffer mechanism 7. The inverter assembly 8 is composed of a circuit board and various components and has no shell. A connecting wire 10 is embedded in the left side wall of the first sealing box 4, and the connecting wire 10 is electrically connected to the leakage protector 9. A wire winding disc 11 is arranged on the left inner wall of the first sealing box 4. A first sealing mechanism 12 is arranged on the right side surface of the first sealing box 4. A plug-in panel 13 is embedded in the right side wall of the second sealing box 6, and the plug-in panel 13 is electrically connected to the inverter assembly 8. A second sealing mechanism 14 is arranged on the left side surface of the second sealing box 6.
[0020] Specifically, the cooling mechanism 2 includes an installation box 201, a semiconductor refrigerator 202, and a temperature control switch 203. The installation box 201 is embedded in the upper side wall of the housing 1. The upper surface of the installation box 201 is an open structure. The semiconductor refrigerator 202 is embedded in the lower side wall of the installation box 201. The temperature control switch 203 is arranged on the lower surface of the installation box 201.
[0021] In this implementation scheme, the mounting box 201 is used to mount the semiconductor refrigeration device 202 on the upper side wall of the housing 1. The temperature control switch 203 is used to detect the temperature inside the housing 1. When the temperature inside the housing 1 is greater than the set value, the semiconductor refrigeration device 202 is turned on. The lower surface of the semiconductor refrigeration device 202 cools the inside of the housing 1, and the heat dissipation fins on the upper surface of the semiconductor refrigeration device 202 exchange heat with the heat dissipation fan.
[0022] Specifically, the buffer mechanism 7 includes a third locking bolt 701, a spring-damper shock absorber 702, and a mounting bracket 703. Spring-damper shock absorbers 702 are installed at the four corners of the left side surface of the first sealing box 4 and the right side surface of the second sealing box 6 through the third locking bolts 701, and a mounting bracket 703 is fixedly installed between the left and right spring-damper shock absorbers 702.
[0023] In this implementation scheme, the third locking bolts 701 connect and fix the left and right spring-damper shock absorbers 702 to the first sealing box 4 and the second sealing box 6, so that the left and right spring-damper shock absorbers 702 increase the buffer and shock absorption functions of the mounting bracket 703, that is, increase the buffer and shock absorption functions of the inverter assembly 8 and the leakage protector 9.
[0024] Specifically, the cross-section of the mounting bracket 703 is a U-shaped structure, and rectangular openings 15 are provided on the left and right side walls of the mounting bracket 703.
[0025] In this implementation scheme, the rectangular openings 15 on the mounting bracket 703 do not affect the cooling and the installation of the standard wires.
[0026] Specifically, the first sealing mechanism 12 includes a sealing cover 121, a lock 122, and a long slot 123. The sealing cover 121 is hingedly installed on the right side surface of the rear side wall of the first sealing box 4. The sealing cover 121 is locked and fixed to the front side wall of the first sealing box 4 through the lock 122, and a long slot 123 is provided on the lower surface of the sealing cover 121.
[0027] In this implementation scheme, the lock 122 enables the sealing cover 121 to seal the right side surface of the first sealing box 4, and the long slot 123 allows the wires to pass through.
[0028] Specifically, the second sealing mechanism 14 has the same structure as the first sealing mechanism 12.
[0029] In this implementation scheme, the second sealing mechanism 14 can seal the left side surface of the second sealing box 6.
[0030] In use, open the latch 122 in the first sealing mechanism 12 to open the sealing cover 121, remove the connecting wire 10 from the wire reel 11, and extend the connecting wire 10 through the long slot 123. Then, lock and fix the sealing cover 121 to the first sealing box 4 through the latch 122. Similarly, open the second sealing mechanism 14, insert the plug into the plug-in panel 13, and then close the second sealing mechanism 14 to protect the plug-in panel 13. Also, the cable of the plug also extends through the long slot 123 in the second sealing mechanism 14 to block the plug, making it not easy for the plug to loosen or fall off. Connect and fix the left and right spring-damper shock absorbers 702 to the first sealing box 4 and the second sealing box 6 through the third locking bolt 701 in the buffer mechanism 7, so as to enhance the buffer and shock absorption function of the mounting bracket 703 by the left and right spring-damper shock absorbers 702, that is, enhance the buffer and shock absorption function of the inverter assembly 8 and the leakage protector 9, making the inverter assembly 8 and the leakage protector 9 not easy to be damaged by vibration. Then, the temperature control switch 203 in the cooling mechanism 2 is used to detect the temperature inside the housing 1. When the temperature inside the housing 1 is greater than the set value, the semiconductor refrigerator 202 is turned on, and the lower surface of the semiconductor refrigerator 202 cools the inside of the housing 1. The leakage protector 9 enhances the leakage protection function of this vehicle-mounted inverter. After use, the connecting wire 10 can be stored, not easily leaking and being damaged, and the plug-in panel 13 is not easily contaminated by dust and rainwater.
[0031] In summary, this vehicle-mounted inverter with a leakage protection structure enhances the leakage protection function of this vehicle-mounted inverter, can cool down under a sealed state with better cooling effect, is not easy for dust and rainwater to enter, enhances the buffer and shock absorption function of the inverter assembly 8 and the leakage protector 9, is not easily damaged by vibration, meanwhile enhances the storage function of the connecting guide, enhances the protection function of the plug-in panel 13, makes the plug not easy to loosen or fall off, and is more conducive to use.
