[0002] Nowadays, the application scope of car charger plugs on vehicles has been expanded. They can not only be connected to cigarette lighters, but also to USB ports, etc., to meet different power needs. The diversification of usage scenarios has also brought about many problems, and new solutions are urgently needed for efficient protection of car charger port discharge.

[0003] The existing protection for car charger plugs is limited to overcurrent protection. When the car charger plug discharges and overheats, the protection action cannot be performed, and the shell may even be burned. In actual applications, the product shell needs to have a higher temperature resistance level. In addition, after the protection is triggered, the car charger plug needs to be replaced before it can continue to be used, further increasing the cost of use.

[0004] Another solution is to use NTC (thermistor) for temperature sampling and use the control module to control the on and off of the discharge circuit for protection. This method requires the control circuit to transmit and process temperature information at multiple levels, which is more complex and less efficient. Summary of the invention

[0008] Therefore, by setting the switch component in series with the car charger plug and electrically connecting the temperature collector to the switch component, the temperature collector can collect the temperature at the hot spot of the car charger plug, and the switch component can be selectively opened and closed according to the temperature collected by the temperature collector, so as to control the discharge of the car charger plug. Such a setting can not only simplify the structure of the vehicle charger plug assembly, but also make the over-temperature protection of the vehicle charger plug assembly easy to implement without the need to additionally set up a controller to control the discharge of the car charger plug, and can also improve the efficiency of the over-temperature protection of the vehicle charger plug assembly.

[0024] The embodiments of the present utility model are described in detail below. The embodiments described with reference to the accompanying drawings are exemplary. The embodiments of the present utility model are described in detail below.

[0025] Reference below Figure 1 A vehicle charger plug assembly 100 for a vehicle according to an embodiment of the present invention is described. The vehicle charger plug assembly 100 for a vehicle can be applied to a vehicle.

[0026] Combination Figure 1 As shown, the vehicle charger plug assembly 100 of the vehicle according to the utility model can mainly include: a vehicle charger plug 10, a switch component 20 and a temperature collector 30, wherein the switch component 20 is arranged in series with the vehicle charger plug 10, the switch component 20 is selectively opened and closed to control the vehicle charger plug 10 to selectively discharge, and the temperature collector 30 is used to be arranged at the hot spot of the vehicle charger plug 10, and the temperature collector 30 is electrically connected to the switch component 20.

[0027] Specifically, the switch element 20 is connected in series with the car charger plug 10. When the switch element 20 is closed, the car charger plug 10 forms a stable discharge circuit, so that the user can normally use the car charger plug 10 to charge related electrical appliances and light a cigarette. When the switch element 20 is opened, the discharge circuit of the car charger plug 10 is disconnected. At this time, the car charger plug 10 is in a state where it cannot work normally, thereby ensuring the safety of the car charger plug 10.

[0028] Furthermore, the temperature collector 30 is electrically connected to the switch component 20, and the temperature collector 30 is set at the hot spot of the car charger plug 10. The temperature collector 30 can collect the temperature at the hot spot of the car charger plug 10, and transmit the temperature signal to the switch component 20 to control the opening and closing of the switch component 20. When the temperature at the hot spot of the car charger plug 10 collected by the temperature collector 30 is less than a preset value, the temperature collector 30 controls the switch component 20 to be continuously in a closed state, so that the discharge circuit of the car charger plug 10 is continuously in a stable state, thereby ensuring that the car charger plug 10 can work normally.

[0029] When the temperature at the hot spot of the vehicle charger plug 10 collected by the temperature collector 30 is greater than or equal to the preset value, the temperature collector 30 controls the switch 20 to be in the open state. At this time, the temperature of the vehicle charger plug 10 is relatively high. If it continues to work normally, the outer shell will be burned, and even the personal safety of the driver and passengers inside the vehicle will be threatened. Therefore, the switch 20 in the open state can disconnect the discharge circuit of the vehicle charger plug 10, so that the vehicle charger plug 10 will not continue to heat up. Such a setting can not only ensure the stability and reliability of the over-temperature protection of the vehicle charger plug 10, but also make the structure of the vehicle charger plug assembly 100 simpler, and can improve the efficiency of the over-current protection of the vehicle charger plug assembly 100. In addition, this can also reduce the volume of the vehicle charger plug assembly 100, and can make the vehicle charger plug assembly 100 lighter.

[0030] Furthermore, with such a configuration, the vehicle charger plug assembly 100 of the vehicle will not affect the structure of the vehicle charger plug 10 during the over-temperature protection process. When the temperature drop of the vehicle charger plug 10 is less than the preset value and the discharge fault is eliminated, the switch component 20 is closed again, and the vehicle charger plug 10 can continue to be used without replacing the vehicle charger plug 10. The service life of the vehicle charger plug 10 can be improved, which not only facilitates the user's use, but also reduces the user's cost of using the vehicle, thereby improving the user's use experience.

[0031] Furthermore, with such a configuration, the switch element 20 can directly control the discharge and disconnection of the vehicle charger plug 10 by opening and closing, without the need to additionally set up a controller to control the vehicle charger plug 10. This can not only make the structure of the vehicle charger plug assembly 100 simpler, but also further improve the efficiency of over-temperature protection of the vehicle charger plug 10.

[0032] Therefore, by setting the switch component 20 in series with the vehicle charger plug 10, and electrically connecting the temperature collector 30 to the switch component 20, the temperature collector 30 can collect the temperature at the hot spot of the vehicle charger plug 10, and the switch component 20 can be selectively opened and closed according to the temperature collected by the temperature collector 30, so as to control the discharge of the vehicle charger plug 10. Such a setting can not only simplify the structure of the vehicle charger plug assembly 100 of the vehicle, but also make the over-temperature protection of the vehicle charger plug assembly 100 easy to implement without the need to additionally set up a controller to control the discharge of the vehicle charger plug 10, and can also improve the efficiency of the over-temperature protection of the vehicle charger plug assembly 100.

[0033] In some embodiments of the present invention, the temperature collector 30 is a heat conductor. The temperature collector 30 is set as a heat conductor. The heat conductor can directly transfer the heat at the hot spot of the car charger plug 10 to the switch element 20, so that the switch element 20 is selectively opened and closed according to the temperature of the heat transferred by heat conduction. This not only makes the structure of the temperature collector 30 and the principle of collecting temperature simpler and more direct, but also can further improve the efficiency of collecting temperature by the temperature collector 30 and control the opening and closing of the switch element 20, so as to further optimize the structural design of the car charger plug 10 of the vehicle.

[0034] In some embodiments of the utility model, the heat conductor is a metal heat conductor. Setting the heat conductor as a metal heat conductor can not only ensure the structural strength and reliability of the heat conductor, but also make the heat collection efficiency of the heat conductor at the hot spot of the car charger plug 10 higher, thereby further improving the thermal conductivity of the heat conductor, and further improving the efficiency of the switch component 20 in controlling the discharge circuit of the car charger plug 10 to be turned on or off.

[0035] In some specific embodiments of the present invention, the metal heat conductor includes at least one of a nickel heat conductor, a copper heat conductor, an aluminum heat conductor, and a tungsten heat conductor. Specifically, according to the use environment, process requirements, and production costs of the vehicle charger plug 10, the metal heat conductor can be set to at least one of a nickel heat conductor, a copper heat conductor, an aluminum heat conductor, and a tungsten heat conductor, which can not only make the metal heat conductor applicable to different environments, but also improve the applicability of the metal heat conductor, and also facilitate the production and manufacturing of the vehicle charger plug assembly 100.

[0036] In some embodiments of the utility model, the switch component 20 may mainly include two switch pieces, and the two switch pieces may be selectively moved away from or close to each other to realize the opening and closing of the switch component 20. Specifically, the two switch pieces are set to be selectively moved away from or close to each other. When the temperature collected by the temperature collector 30 is greater than the preset value, the two switch pieces are moved away from each other, so that the switch component 20 is opened, and then the discharge circuit of the vehicle charger plug 10 is disconnected; when the temperature collected by the temperature collector 30 is less than the preset value, the two switch pieces are close to each other, so that the switch component 20 is closed, so that the discharge circuit of the vehicle charger plug 10 is turned on. This can not only further simplify the structural design of the switch component 20, but also make the opening and closing of the switch component 20 simpler and more direct, and can improve the opening and closing efficiency of the switch component 20.

[0037] In some embodiments of the utility model, both switch sheets are metal sheets, and the two metal sheets selectively move away from each other or move close to each other. Specifically, the two switch components 20 are both set as metal sheets. When the temperature collector 30 collects the temperature and transmits it to the two metal sheets, the two metal sheets are heated to generate internal stress, and quickly move away from each other, disconnecting the contacts, so as to prevent the discharge circuit of the car charger plug 10 from continuing to work and continuously generating high temperature to damage the shell of the car charger plug 10. When the circuit fault is eliminated, the temperature of the two metal sheets drops to the preset value, and the two metal sheets automatically move close to each other and fit together, returning to the normal working state, so that the discharge circuit of the car charger plug 10 is continuously turned on. This can further simplify the structural design of the switch component 20, and can further improve the stability and reliability of the switch component 20 when it is opened and closed.

[0038] In some embodiments of the present invention, the temperature collector 30 is arranged in contact with the switch component 20, and the heat at the hot spot of the vehicle charger plug 10 collected by the temperature collector 30 will be directly transferred to the switch component 20, which can improve the efficiency of heat transfer between the temperature collector 30 and the switch component 20, thereby improving the timeliness and reliability of the over-temperature protection of the vehicle charger plug 10 of the vehicle.

[0039] In other embodiments of the present invention, a heat-conducting medium is provided between the temperature collector 30 and the switch component 20. After collecting the heat of the vehicle charger plug 10, the temperature collector 30 transfers the heat to the heat-conducting medium, and then transfers the heat to the switch component 20 through the heat-conducting medium, thereby controlling the opening and closing of the switch component 20. In this way, the temperature collector 30 can transfer the heat to the switch component 20 more evenly, thereby making the opening and closing of the switch component 20 more stable and reliable, which can further optimize the structural design of the vehicle charger plug 10.

[0040] Combination Figure 1 As shown, the vehicle charger plug assembly 100 of the vehicle may also mainly include a current collector 40, and the current collector 40 is electrically connected to the switch element 20. Specifically, the current collector 40 can collect the current in the discharge circuit of the vehicle charger plug 10, and selectively control the switch element 20 to open and close according to the size of the collected current, thereby controlling the on and off of the discharge circuit of the vehicle charger plug 10. When the current collected by the current collector 40 is less than a preset value, the switch element 20 is in a closed state, and the discharge circuit of the vehicle charger plug 10 is continuously in a conducting state. When the current collected by the current collector 40 is greater than a preset value, the switch element 20 is in an open state, thereby disconnecting the discharge circuit of the vehicle charger plug 10, so that overcurrent protection of the vehicle charger plug 10 can be achieved, and the safety and reliability of the vehicle charger plug 10 can be further improved.

[0041] Combination Figure 1As shown, the current collector 40 is arranged in parallel with the temperature collector 30. Specifically, the current collector 40 and the temperature collector 30 are arranged in parallel, and when one of the conditions that the current collected by the current collector 40 is greater than a preset value and the temperature collected by the temperature collector 30 is greater than a preset value is met, the switch element 20 can be opened, so that the discharge circuit of the vehicle charger plug 10 is disconnected, which can not only ensure the reliability of the vehicle charger plug 10 in overcurrent protection and overtemperature protection, but also share a switch element 20, which can simplify the structural design of the vehicle charger plug 10, thereby improving the structural reliability of the vehicle charger plug 10.

[0042] The vehicle according to the embodiment of the utility model includes: the vehicle charger plug assembly 100 of the above-mentioned vehicle. The vehicle charger plug assembly 100 of the above-mentioned vehicle is arranged in the vehicle, which can not only make the structure of the vehicle simpler, but also improve the safety and reliability of the vehicle.
