[0002] With the development of the times, cars have entered ordinary families, bringing great convenience to people's travel, but they will also encounter many problems. For example, the car cannot start in certain special circumstances, which will cause great trouble to users. To solve this problem, the car will be equipped with an emergency starting power supply. Traditional cars generally use batteries to start the engine. When the engine starts, the battery is charged through its own power generation system. Under normal circumstances, the battery power can be balanced, but due to reasons such as aging of the car battery, insufficient charging, long-term storage or cold weather, the battery power will be insufficient and the generator will not start normally, affecting the normal use of the vehicle. At present, emergency starting power supplies have appeared on the market, mainly lead-acid batteries and lithium batteries, but both have the problem of self-consumption of electricity. After being stored for a period of time, they will lose power. If the power cannot be replenished in time, they will not be able to be used when an emergency is needed.

[0003] With the continuous development of automobile technology, automobile emergency starting power supply is an important part of vehicle auxiliary equipment, and its performance and reliability directly affect the safety and user experience of the car.

[0041] Embodiment 1

[0042] refer to Figure 1-10As shown, a car emergency starting power supply with waterproof and dustproof functions includes a shell 2, the shell includes an upper cover 201 and a lower cover 202, the end face of the upper cover 201 is provided with a clamping groove 3, the clamping groove 3 is provided with a cover body sealing ring 4, the end face of the lower cover 202 is provided with a protrusion 5, the upper cover 201 and the lower cover 202 are assembled and installed, the protrusion 5 of the lower cover 202 is inserted into the clamping groove 3 of the upper cover, a control mainboard 1 is installed in the shell 2, the control mainboard 1 is provided with a charging terminal 8, an output terminal 20 and a super capacitor 19 as an energy storage element, two port openings 6 are provided on the shell 2, the charging terminal 8 on the control mainboard 1 is installed in one of the port openings 6, the output terminal 20 is installed in the other port opening, one port opening is arranged on the front side of the shell, and the other port opening is arranged on the back side of the shell, that is, the two port openings are not arranged on the same side. The card groove 3 of the upper cover 201 is formed by two spaced side walls inside and outside. The card groove 3 is arranged around the end face of the upper cover 201 and can be disconnected in the middle to facilitate the assembly of other parts. The cover body sealing ring 4 is embedded in the card groove 3, and then the protrusion 5 of the lower cover 202 is inserted into the card groove 3 and abuts against the cover body sealing ring 4. The upper cover 201 and the lower cover 202 are installed in a snap-fit ​​manner. After the protrusion 5 of the lower cover 202 is inserted into the card groove 3 of the upper cover 201, it is equivalent to forming a middle retaining wall structure between the splicing end faces of the upper cover and the lower cover. There is also an upward protrusion between the splicing gap between the end faces of the upper cover and the lower cover. If water vapor and dust penetrate from the splicing gap, they will also be blocked by the protrusion. Even if they penetrate along the protrusion, they can be effectively blocked by the cover body sealing ring. Therefore, the sealing performance of the shell can be effectively improved by the cover body sealing ring, thereby playing a waterproof and dustproof protective role for the control motherboard and various electronic components inside the shell.

[0043] For the control motherboard 1, a PCBA motherboard with integrated charging and discharging functions is selected, on which various necessary electronic components are integrated. The specific model of the motherboard is not specifically limited here. It can realize the charging and discharging functions and the size meets the assembly requirements.

[0044] By using supercapacitors 19, supercapacitors with high energy density, high power density and long cycle life are used as energy storage elements. These capacitors can provide sufficient starting current in a short time to ensure smooth start of the car, can charge and discharge quickly, and have long life and good low temperature performance.

[0045] In order to further improve the sealing performance, the surface of the control mainboard 1 can be coated with a waterproof coating, and the surface of the supercapacitor is also coated with a waterproof coating, and other electronic components on the control mainboard that can be coated are also provided with a waterproof coating to achieve a stronger dustproof and waterproof effect. The waterproof coating can be a parylene nano coating or other nano waterproof materials, such as polyxylene C or polyxylene N. During preparation, a nano conjunctiva similar to the "lotus leaf effect" can be formed on the PCBA circuit board by vapor deposition, which effectively protects the working ability of electronic components in humid, underwater extreme environments, and enhances the moisture-proof and dust-proof capabilities of electronic components.

[0046] In addition, EPDM foam 12 is attached to the inner bottom surface of the lower cover 202, so that the super capacitor 19 does not directly contact the inner bottom surface of the lower cover 202, but is separated by the EPDM foam. In extreme cases, even if the lower cover is immersed in water, water will first be blocked by EPDM, and then further improve the sealing and waterproof properties.

[0047] During installation, the control mainboard 1 is locked and fixed to the upper cover 201 by screws, and the super capacitor 19 extends downward into the lower cover 202, thereby completing the installation of the control mainboard.

[0048] The charging terminal 8 on the control mainboard 1 can have two or more different types of interfaces at the same time, such as a USB interface, a DC charging interface, and a Type-C interface, to meet the use requirements. The port window involves both the upper cover and the lower cover, wherein most of the space of the port window is located in the upper cover, and a small part of the space is located in the lower cover, and the corresponding areas of the upper cover and the lower cover are hollowed out.

[0049] Embodiment 2

[0050] refer to Figure 1-10 As shown, for the two port openings 6 on the housing 2, if they are directly exposed, external water vapor and dust can easily enter the charging terminal, thereby damaging the charging terminal. Therefore, in order to achieve waterproof and dustproof, and protect the charging terminal 8 and the output terminal 20, a sealing silicone plug 7 is installed in the two port openings 6, and the sealing silicone plug 7 completely covers the port opening 6. When charging is not needed, the sealing silicone plug is installed to prevent external water vapor and dust from entering the housing from the port opening. When charging is needed, the sealing silicone plug can be opened.

[0051] An avoidance groove 9 is provided on one side of the port window 6, and a protrusion 10 is provided on one side of the sealing silicone plug 7. After the sealing silicone plug 7 is installed in the port window 6, the protrusion 10 is clamped in the avoidance groove 9, and there is a gap 11 between the protrusion 10 and the avoidance groove 9. The gap 11 is usually about 0.5 cm. By setting the avoidance groove 9 and reserving the gap 11, when opening the sealing silicone plug 7, a finger or other small tool can be inserted into the gap, and then the sealing silicone plug can be easily pulled open, reducing the difficulty of opening.

[0052] In addition, reference Fig.11 and 12 As shown, a raised plug-in 21 is provided on the inner side of the sealing silicone plug 7, and a barb 24 is provided on the raised plug-in. A limiting plate 22 is provided in the port window 6, and a socket 23 is provided on the limiting plate 22. After the sealing silicone plug 7 is installed in the port window 6, the raised plug-in 21 is inserted into the socket 23, and the barb 24 is inserted from the outside of the socket and enters the inner side of the socket 23. The barb 24 is arranged in the rear position of the raised plug-in 21, so that the barb 24 on the raised plug-in 21 has a certain movable space, that is, when the sealing silicone plug 7 is completely clamped and installed in the port window 6, the barb 24 is located at a deeper position inside the socket 23, and the barb 24 does not contact the inner side of the socket 23, leaving movable space. When the sealing silicone plug 7 is opened, the protruding plug 21 is pulled outward for a distance until the barb 24 abuts against the inner side of the insertion hole 23. At this time, the sealing silicone plug 7 is blocked. When no large outward pulling force is applied to the sealing silicone plug 7, the sealing silicone plug 7 will not fall off completely, but will be in a hanging state, thereby avoiding the problem of placing the sealing silicone plug aside and being easily missed when opening.

[0053] The raised plug-in and the protruding portion are integrally formed on the sealing silicone plug and are integrally processed and formed.

[0054] Embodiment 3

[0055] refer to Figure 1-10 As shown, in order to improve safety during the charging and discharging process, a temperature sensor is provided around the supercapacitor, and the temperature sensor is connected to the control mainboard. The temperature sensor can be installed with the lower cover or the upper cover through a bracket. The temperature sensor is used to detect the temperature of the supercapacitor in real time, and accurate monitoring is achieved by presetting the temperature. By setting the control application on the control mainboard, the temperature of the supercapacitor is monitored and controlled in real time to ensure normal operation in high and low temperature environments.

[0056] The input end of the super capacitor is connected to an overcurrent protection module, and the output end of the super capacitor is connected to an overvoltage protection module, which are integrated on the control main board. When the current and voltage are too large, they can be disconnected in time to ensure that the super capacitor will not be damaged under abnormal circumstances.

[0057] The upper cover 201 is provided with a display opening 13, and a display screen 14 is provided inside the display opening. The display screen is connected to the control mainboard. A display screen cover plate 16 can be installed at the display opening 13 to protect the display screen. A fixing block 15 can also be provided inside to fix the display screen. Operation buttons can also be provided to be displayed on the upper cover. The surface of the upper cover is provided with a PC mask, and a display portion facing the display screen is provided on the PC mask. The display screen can be used to set the display of relevant parameters, such as the current power and charging parameters, and the PC mask, in addition to playing a protective role, can also be waterproof and dustproof. For better assembly, a sunken groove cavity can be provided on the upper end face of the upper cover, and then the PC film can be installed in the groove cavity. After assembly, it remains flush with the upper end face of the upper cover, and the structure is more compact.

[0058] In addition, a non-slip foot pad is provided on the bottom surface of the lower cover, so that the shell is not easily displaced when placed, thus achieving a stabilizing effect.

[0059] The utility model plays an effective role in waterproofing and dustproofing through various sealing settings. Among them, the cover sealing ring in the upper cover can form the first seal inside the shell, the sealing silicone plug is used as a seal for the separate port window, the waterproof coating on the surface of the control motherboard and the super capacitor can form the second seal, and the EDPM foam can be sealed again, so as to have multiple seals.
