Abstract
Description
Technical Field
[0001] This utility model belongs to the field of new energy vehicle accessories, specifically relating to a vehicle power socket. Background Technology
[0002] With the rapid development of the automotive industry and the upgrading of consumer demand, automobiles have gradually evolved from simple means of transportation into multifunctional mobile spaces integrating travel, office work, and leisure. Users' power needs in and around the vehicle are becoming increasingly diversified, extending beyond traditional car chargers for small digital devices such as mobile phones and navigation systems to include medium- and high-power electrical appliances such as laptops, portable home appliances, outdoor camping equipment, and emergency tools. Especially in scenarios such as long-distance travel, outdoor camping, and mobile office work, users' demand for a continuous and stable AC power supply is becoming increasingly urgent. A car power socket is a socket located inside the vehicle that provides 220V AC power, allowing drivers and passengers to use small electrical devices such as laptops while also providing charging services.
[0003] However, with the widespread adoption of in-vehicle power outlets, their safety and reliability issues have become increasingly prominent. Existing products generally lack effective plug-in / plug-out protection mechanisms, exposing users to safety hazards such as electric arcs and sparks during live operation. In terms of electrical protection, there is currently an over-reliance on single protection modules, lacking multi-layered safety protection designs. Utility Model Content
[0004] The technical problem to be solved by this utility model is to provide a vehicle power socket with multiple safety protections.
[0005] To solve the above problems, the technical solution adopted by this utility model includes: a socket housing, a socket panel disposed at the upper end of the socket housing, and a set of springs disposed inside the socket housing. The upper end of the socket housing is provided with a first protective door and a second protective door that slide relative to each other. A first return spring is provided between the first protective door and the second protective door. A trigger rod is provided between the first protective door and the second protective door of the socket housing. The relative sliding of the first protective door and the second protective door drives the trigger rod to move downward. The socket housing is provided with a main control board connected to the lower end of the spring. The main control board is provided with a set of terminals that are electrically connected to the spring and a micro switch that cooperates with the trigger rod. A fuse and / or a temperature control switch are provided on the circuit between the terminal and the spring.
[0006] The trigger rod has a first inclined surface on both sides of the upper end and a second reset spring on both sides of the lower end. The first protective door and the second protective door have a second inclined surface that applies pressure to the first inclined surface.
[0007] The end of the first inclined surface is provided with a positioning step.
[0008] The trigger lever is equipped with guide rails on both sides.
[0009] The terminal block is provided with wiring terminals, and the socket housing is provided with wiring ports on one side.
[0010] The socket housing has a bottom cover, and a connector plug is provided on the bottom cover. The main control board has a connector socket that mates with the connector plug. The socket housing is provided with a light guide post, the upper end of which extends out of the socket panel and the lower end is close to the power indicator light on the main control board.
[0011] One side of the temperature control switch is attached to one of the springs.
[0012] The advantages of this multi-safety vehicle power socket are as follows: 1. It achieves dual protection of physical isolation and electrical connection / disconnection through the protective doors and micro switches, effectively preventing the risk of plugging and unplugging while the power is on; at the same time, the temperature control switch is tightly fitted with the socket to directly monitor the temperature of the electrical connection point, providing precise protection against slow temperature rise faults caused by increased contact resistance, continuous overload, etc., and the fuse is used to cut off instantaneous high current faults such as short circuits. The two together form a multi-faceted protection covering instantaneous and progressive faults; 2. The plug of the electrical equipment pushes the two safety doors to move towards the center, and the inclined surface of the safety doors applies pressure to the inclined surfaces on both sides of the trigger rod, causing the trigger rod to move downward, thereby triggering the micro switch very stably.
[0013] The present invention will be further described below with reference to the accompanying drawings. Attached Figure Description

Detailed Implementation
[0015] Reference Figure 1-7As shown, the multi-safety vehicle power socket of this utility model includes a socket housing 1, a socket panel 2 disposed on the upper end of the socket housing 1, and a set of springs 3 disposed inside the socket housing 1. The springs 3 consist of an L spring, an N spring, and a PE socket. The upper end of the socket housing 1 is provided with a first protective door 4 and a second protective door 5 that slide relative to each other, and a first return spring 6 is provided between the first protective door 4 and the second protective door 5. The socket housing 1 is provided with a trigger rod 7 between the first protective door 4 and the second protective door 5, and the trigger rod 7 moves downward by the relative sliding of the first protective door 4 and the second protective door 5. The socket housing 1 is provided with a main control board 8 connected to the lower end of the springs 3. The main control board 8 is provided with a set of terminal blocks 9 that are electrically connected to the springs 3 and a micro switch 10 that cooperates with the trigger rod 7. A fuse 11 and a temperature control switch 12 are provided on the circuit between the terminal block 9 and the springs 3. The temperature control switch 12 monitors the temperature of the electrical connection point in real time by tightly fitting the electrical socket. When the temperature at the monitoring point exceeds the preset safety threshold due to continuous high current operation or high ambient temperature, the temperature control switch will immediately and automatically cut off the circuit. The fuse provides overcurrent and short-circuit protection in the circuit; it will melt immediately upon detecting a short circuit or abnormally high current. Preferably, the upper end of the trigger lever 7 is provided with first inclined surfaces 13 on both sides, and the lower end of the trigger lever 7 is provided with second return springs 14 on both sides. The first protective door 4 and the second protective door 5 are provided with second inclined surfaces 15 that apply pressure to the first inclined surfaces 13. When the plug of the electrical device is inserted, it pushes the two safety doors to move towards the center, and the inclined surfaces of the safety doors apply pressure to the trigger levers on both sides of the trigger lever, causing the trigger lever to move downward, thereby triggering the micro switch very stably. The micro switch sends a power supply signal request to the vehicle power management system, and then the vehicle powers the socket, so that the socket is not energized when no electrical device is connected, thereby greatly improving safety.
[0016] Preferably, the end of the first inclined surface 13 is provided with a positioning step 16. When the trigger lever 7 is reset upward, the positioning step 16 is positioned on the socket housing 1 to perform a positioning function.
[0017] Preferably, guide rails 17 are provided on both sides of the trigger lever 7. Guide rail grooves adapted to the guide rails 17 are provided on the socket housing 1 to improve the stability of the trigger lever 7 sliding up and down.
[0018] Preferably, the terminal block 9 is provided with a terminal block 20, which is connected to the terminal block 9 by screws. A wiring port 21 is provided on one side of the socket housing 1 to facilitate connection to an input power source.
[0019] Preferably, the socket housing 1 has a lower housing cover 22 at its bottom, and a connector plug 23 is provided on the lower housing cover 22. The main control board 8 has a connector socket 24 that engages with the connector plug 23, so as to facilitate connection of the output power from below.
[0020] Preferably, the socket housing 1 is provided with a light guide post 25, the upper end of which extends out of the socket panel 2 and the lower end is close to the power indicator light 26 on the main control board 8. When power is applied, the power indicator light 26 lights up and is transmitted through the light guide post 25 for easy observation by the user.
