Description

Technical Field

[0001] This utility model relates to the field of power supply technology, and in particular to a low-temperature resistant automotive starting power supply. Background Technology

[0002] A car jump starter, also known as a car emergency jump starter, is a portable power supply that integrates power supply and charging functions, developed for car enthusiasts and business people. Its key feature is that it can start a car when the battery is dead or for other reasons. It also combines an air pump with emergency power, outdoor lighting, and other functions, and can charge mobile phones, tablets, and other digital devices anytime, anywhere. It typically uses lithium-ion batteries as its energy storage unit. Compared to mobile phone power banks, car jump starters have a larger capacity and are more convenient and faster to use. According to announcement number CN219677422U, a low-temperature car jump starter is disclosed, belonging to the field of jump starter technology. A low-temperature automotive starting power supply includes a power supply housing, a battery pack fixedly connected inside the housing, and a heating element electrically connected to the battery pack fixedly installed inside the housing. It also includes a bladder fixedly installed inside the housing, the bladder being filled with helium gas; and a heat-insulating block fixedly connected inside the housing, with multiple sets of irregularly distributed pores. This invention, by fixing the bladder inside the housing, allows the helium gas to expand during heating, causing the bladder to expand and envelop the battery pack housing. This reduces or prevents the battery pack from shaking or colliding with other objects, thus reducing damage and extending its lifespan. The bladder also helps to lock in temperature, slowing down the temperature drop and preventing the heating element from being activated repeatedly in a short period, increasing battery power consumption and extending operating time. However, this technology still has some drawbacks. For example, existing power supplies have exposed interfaces, which are prone to accumulating impurities after prolonged use, rendering them unusable. Improvements are needed. Utility Model Content

The fixing plate 15 further secures the cover plate 13 to the side of the power supply body 1, thus protecting the interface 9. This prevents the interface 9 from being directly exposed and accumulating impurities after prolonged use, which could render it unusable. (Support pad) 2. The limiting grooves A29 are evenly distributed at the four corners of the bottom of the power supply body 1. The conductive sheets 3 are symmetrically distributed at the left and right ends of the top of the power supply body 1.

[0026] Example 2

[0027] Please see Figure 1-3 6. A storage box 20 is installed on the surface of the power supply body 1. The top of the storage box 20 has a storage slot 21. A soft plug 22 is installed inside the storage slot 21. A protective plate 23 is installed on the top of the soft plug 22. A protective cover 24 is installed on the surface of the conductive sheet 3. A protective groove 25 is opened inside the protective cover 24. An outer plate 26 is installed at the bottom of the protective cover 24. A gasket 27 is installed on the inner wall of the outer plate 26, providing an additional protective layer to prevent dust, moisture and other external factors from damaging the inside of the power supply. The design of the protective cover 24 and the protective groove 25 on the surface of the conductive sheet 3 further protects the conductive sheet 3 from physical damage and environmental influences. The outer plate 26... The inner wall is fitted with a retainer 27, which increases the stability and reliability of the connection, while reducing wear and extending the service life. The soft plug 22 is slidably connected to the storage box 20 through the storage groove 21, the protective plate 23 is slidably connected to the storage box 20, the cover 24 is slidably connected to the conductive sheet 3 through the protective groove 25, and the retainer 27 is slidably connected to the conductive sheet 3 to adapt to different usage scenarios. The design of these sliding connections increases the flexibility and convenience of use, while ensuring the stability and reliability of the connection.

[0028] Working principle: When using, first pull the handle 7 upwards, causing it to rotate inside the fixed block 4 via the rotating rod 6 and rotating groove 5, and then rotate out of the insulation shell 28 through the storage groove 31. Once the handle 7 is completely perpendicular to the top of the power supply body 1, place the power supply body 1 in the desired position, ensuring the support pad 2 inside the limiting groove A29 firmly supports it. Then, squeeze the handle 19 and rotate it, causing the threaded rod 18 to rotate backwards inside the protrusion 16 via the threaded groove 17. Once the threaded rod 18 has completely rotated out of the protrusion 16 through the threaded groove 17 and rotated out through the slot 11... After inserting the cover into block 10, pinch the pull block 14 and pull it to the side, causing the cover plate 13 to rotate upward on the side of the power supply body 1 via the hinge 12. Once the cover plate 13 is fully opened via the hinge 12, and the protrusion 16 is fully opened via the fixing plate 15, the wiring is then fixed to the side of the power supply body 1 via the interface 9 and the groove 8. When the vehicle power supply is low, pinch the cover 24 and pull it upward, causing the cover 24 to slide upward on the surface of the conductive sheet 3 via the protective groove 25. The outer plate 26 also causes the pad 27 to slide upward. Once the cover 24 has completely slid out of the surface of the conductive sheet 3 via the protective groove 25... After the outer plate 26 drives the pad 27 to slide completely out of the surface of the conductive sheet 3, the wires can be connected to the conductive sheet 3 and the vehicle power supply respectively. After use, the wires can be placed inside the storage box 20 through the storage slot 21. Then, pinch the protective plate 23 and press the soft plug 22 down to align it with the storage slot 21, so that the soft plug 22 slides completely into the storage box 20 through the storage slot 21 and the protective plate 23 is attached to the top of the storage box 20. Finally, pinch the pull block 14 and press it against the power body 1, so that the cover plate 13 is completely attached to the side of the power body 1 through the hinge 12. Then, align the threaded rod 18 with the threaded rod. The screw 18 is rotated through the groove 17 and the handle 19 is rotated so that the screw rod 18 is completely rotated into the inside of the protrusion 16 through the screw groove 17, and then rotated into the inside of the side block 10 through the slot 11. This allows the screw rod 18 to firmly fix the cover plate 13 to the side of the power supply body 1 through the fixing plate 15, thereby protecting the interface 9. In the face of low temperature environment, the heat insulation shell 28 can effectively protect the power supply body 1 and avoid the situation that the power supply body 1 will not perform well due to low temperature environment. Since the heat insulation shell 28 is fixed to the surface of the side block 10 through the limiting groove B30, it can prevent low temperature from drifting into the inside of the power supply body 1 through the gap.
