Description

Technical Field

[0001] The utility model relates to the technical field of vehicle power supplies, and specifically relates to an automotive vehicle power supply charging and discharging system and a power adapter thereof. Background Technique

[0002] The vehicle external power supply system, as an innovation in modern automotive technology, has become an important tool for enhancing the outdoor endurance of vehicles. It not only provides a powerful mobile power solution for users far from cities and traditional power facilities, but also greatly enriches the users' outdoor experience by supporting the operation of various electronic devices. Whether it is for scientific research in remote areas, camping in the wild, or in case of emergency when temporary power is needed, the vehicle external power supply shows its indispensable role.

[0003] However, the complexity and unpredictability of the outdoor environment pose higher requirements for the stability and reliability of the vehicle external power supply. Under changing weather conditions, such as sudden rain or snow, the waterproof performance of the power supply system becomes crucial. Once rainwater seeps into the jacks, it may not only cause a short circuit, but also corrode the electronic components inside the power supply system, increasing the maintenance cost and usage risk. In addition, the common dust and sand in the outdoor environment also pose a threat to the power supply system that cannot be ignored. These tiny particles are easy to clog the jacks, affecting the stability of the electrical connection. Over time, they may also wear the jacks, reducing the reliability of the contact. In extreme cases, these particles may even cause a power failure, resulting in equipment damage and affecting the normal use of users.

[0004] In addition, some current connectors have certain protection capabilities. For example, a protective shell is installed at the connector, which is opened during use and closed when not in use. However, in some cases, not all the sockets on these connectors need to be used. Therefore, when using some of the sockets, opening the protective shell will cause the other sockets to lose protection, resulting in inconvenience in use.

[0005] Therefore, we propose an automotive vehicle power supply charging and discharging system and a power adapter thereof to solve the problems raised above.

[0006] The above information disclosed in this background technique is only used to increase the understanding of the background technique of the present invention. Therefore, it may include prior art that is not known to those of ordinary skill in the art. Content of the Utility Model

Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. It should be noted that the drawings are schematic and not drawn to scale. For the sake of clarity and convenience in the figure, the relative dimensions and proportions of the parts shown in the figure are exaggerated or reduced in size and illustrated. Any dimension is only exemplary and not limiting.

[0045] Embodiment 1:

[0046] Please refer to Figures 1 - 5 , an in-vehicle power charging and discharging system for an automobile and its power adapter, including: a discharging connector 1, a charging connector 2, and a power supply box 5. The discharging connector 1 is electrically connected to the power supply box 5 through a discharging wire 3, and the charging connector 2 is electrically connected to the power supply box 5 through a charging wire 4. The discharging connector 1 includes a housing 101. Insertion slots 102 are provided on both sides of the housing 101. The housing 101 is provided with a baffle 103 that is sized to match the insertion slots 102 and has an arc shape that matches the housing 101. The housing 101 and the baffle 103 are fixed by a connector 104. The housing 101 includes a cylindrical mounting shell 1011. The mounting shell 1011 is provided with a first insertion hole 1012 at the position of the insertion slot 102. The mounting shell 1011 is provided with a second insertion hole 1014 inside the baffle 103. The mounting shell 1011 is provided with arc-shaped grooves 1015 on both sides of the baffle 103. The baffle 103 is movably clamped in the arc-shaped grooves 1015. The connector 104 passes through the baffle 103 and is inserted into the second insertion hole 1014. The baffle 103 includes a first arc-shaped plate 1031. Arc-shaped rods 1032 are fixed on both sides of the first arc-shaped plate 1031. The arc-shaped rods 1032 are adapted to the arc-shaped grooves 1015 and are clamped in the arc-shaped grooves 1015. The connector 104 includes a second arc-shaped plate 1041. An insertion rod 1042 is fixed to the second arc-shaped plate 1041. The insertion rod 1042 passes through the first arc-shaped plate 1031 and is inserted into the second insertion hole 1014.

[0047] In use, in the initial state, the end of the insertion rod 1042 is inserted into the second insertion hole 1014. The insertion rod 1042 and the second insertion hole 1014 are mutually adapted. Therefore, there is a certain pressure between the insertion rod 1042 and the mounting shell 1011 to prevent it from coming out. The jack on the mounting shell 1011 is exposed, and the user can insert an external plug into the jack for use. When not in use, the insertion rod 1042 can be first pulled out, and it drives the baffle 103 to move to a suitable position, and then the insertion rod 1042 is inserted into the first insertion hole 1012 to protect the jack. The arc-shaped rod 1032 is closely connected to the arc-shaped groove of the mounting shell 1011 and has a certain sealing effect to prevent rain and snow from falling into it.

[0048] Embodiment 2:

[0049] Refer to Figure 6 , on the basis of Embodiment 1, a first magnet 1013 is provided in the first insertion hole 1012 and the second insertion hole 1014, and a second magnet 1043 is provided at the end of the insertion rod 1042. The first magnet 1013 and the second magnet 1043 have opposite magnetic polarities.

[0050] In this embodiment, the diameter of the insertion rod 1042 is slightly smaller than the diameters of the first insertion hole 1012 and the second insertion hole 1014. During use, fastening is achieved by the mutual attraction of the first magnet 1013 and the second magnet 1043, and the operation is more convenient.

[0051] Refer to Figure 7 , an on-vehicle power charging and discharging system for an automobile, including a power adapter for an on-vehicle power charging and discharging system of an automobile, as well as a storage battery 6, a bidirectional inverter 7, and a charge and discharge conversion circuit 8. The bidirectional inverter 7 is electrically connected to the storage battery 6, and the charge and discharge conversion circuit 8 is electrically connected to the bidirectional inverter 7. The bidirectional inverter 7 and the charge and discharge conversion circuit 8 are installed in the power box 5. The power box 5 and the storage battery 6 are both installed inside the on-vehicle power supply. The charging wire 4 and the discharging wire 3 both extend out of the on-vehicle power supply.

[0052] Working principle: When the storage battery 6 needs to discharge, the user inserts an external plug into one of the sockets on the mounting shell 1011. When not in use, first pull out the second arc-shaped plate 1041 outward so that its end leaves the second insertion hole 1014. Control the first arc-shaped plate 1031 to move through the second arc-shaped plate 1041 until the first arc-shaped plate 1031 covers the socket, and the first insertion hole 1012 is aligned with the insertion rod 1042, and then insert the insertion rod 1042 so that the second arc-shaped plate 1041 fits on the first arc-shaped plate 1031.
