Description

Technical Field

[0001] The utility model relates to the technical field of vehicle chargers, in particular to a universal vehicle charger for front and rear rows of a vehicle. Background Art

[0002] With the development of the automobile industry, on-board chargers are widely used, showing the characteristics of versatility, portability and fashion. On-board chargers refer to on-board chargers that are conventionally powered by car batteries. They are widely used in the field of lithium battery charging of various portable and handheld devices. On-board chargers must consider both the actual needs of lithium battery charging and the harsh environment of car batteries. Therefore, the power management IC selected for the car charging solution must meet the following requirements at the same time: high voltage resistance, high efficiency, high reliability, and low frequency switching power supply chip.

[0003] The car charger is an accessory designed to facilitate car owners to charge digital products anytime and anywhere with the car charging power supply. This type of product generally has overload protection, short circuit protection, high voltage input protection, high temperature protection, and four safety protection functions to ensure safe use. The car charger generally has overload protection, short circuit protection, high voltage input protection, high temperature protection, and four safety protection functions to ensure that you can use it safely.

[0004] At present, when using the car charger, it is usually necessary to insert the car charger into the cigarette lighter or the USB interface, and then the car charger can be charged, so that the data cable is inserted into the USB interface on the outer surface of the car charger for use.

[0005] However, when using the car charger, since the cigarette lighter is generally located at the top of the central armrest of the car, the car charger is located in the middle of the front row of the car. Therefore, the location of the car charger is not convenient for the passengers in the back seat of the car to charge, which affects the use of the car charger in the back seat of the car. Utility Model Content

[0006] Based on this, the purpose of the utility model is to provide a universal car charger for the front and rear rows of a car to solve the technical problem that during the use of the car charger, since the cigarette lighter is generally located at the top of the central armrest of the car, the car charger is located in the middle of the front row of the car, so the location of the car charger is not convenient for the passengers in the back row of the car to charge, which affects the use of the car charger in the back row of the car.

[0007] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a universal on-board charger for the front and rear rows of a car, comprising a connector, a plug is provided on the bottom plate of the connector, and a plurality of second sockets are provided on the top of the connector, a group of symmetrical slide grooves are provided on one side of the connector, a slider matching the slide groove is slidably connected in the slide groove, one end of the slider is fixedly connected to a connecting block, and a cavity is provided in the connecting block, a rotating shaft is rotatably connected in the cavity, one end of the data cable is connected to the outer surface of the rotating shaft, and the other end of the data cable is connected to one end of the first socket, the first socket movably passes through one side of the cavity and extends to the outside, and the rotating shaft and the cavity are connected by a coil spring.

[0008] By adopting the above technical solution, when the rear passengers of the car use the car charger, they can first insert the plug at the bottom of the connecting block into the cigarette lighter, and then adjust the position of the slider in the slide groove so that the connecting block can be close to both sides of the central armrest of the car, and then pull the first socket exposed outside the cavity, so that the first socket drives the data cable to move toward the rear row, which is conducive to the first socket being closer to the rear row of the car, making it easier for the rear passengers to charge their electronic devices, thereby improving the use of the car charger by the rear passengers.

[0009] The utility model is further configured that a thread groove is provided on the top of the slide groove, and a bolt whose size and position match the thread groove is threadedly connected in the thread groove, and the bottom of the bolt is fixedly connected to the top of the slide block.

[0010] By adopting the above technical solution, through the setting of the thread groove and the bolt, when the bolt slides in the thread groove, the slider can be synchronously driven by the bolt to move in the slide groove, and the bolt is turned after moving to the appropriate position, so the position of the slider can be fixed by extrusion, so that the connecting block can be adjusted according to the actual width of the central armrest, so that it can be located on both sides of the central armrest, so that the on-board charger can be better used.

[0011] The utility model is further configured that one side of the sliding block is fixedly connected with an elastic block.

[0012] By adopting the above technical solution, an elastic block is fixedly connected to one side of the slider, which is beneficial to increase the friction between the slider and the slide groove through the elastic block, so that the slider is not easy to slide in the slide groove, so the position of the slider is better fixed, thereby increasing its stability in use.

[0013] The utility model is further configured that the connecting member is internally threadedly connected with a pair of threaded rods, the bottom of each threaded rod is rotatably connected with a support block, and the top of each threaded rod is fixedly connected with a torsion block.

[0014] By adopting the above technical solution, after the plug at the bottom of the connector is inserted into the cigarette lighter, the twist block can be twisted at the top of the connector to drive the threaded rod to rotate, so that the support block moves downward until it contacts the top of the center armrest. This is beneficial for increasing the stability of the connector through the support block, and avoiding the connector being suspended due to the cigarette lighter being higher than the center armrest, which affects the use of the connector.

[0015] The utility model is further configured that a rubber layer is provided at the bottom of the support block, and an anti-slip layer is provided on the outer surface of the twist block.

[0016] By adopting the above technical solution, by providing a support layer at the bottom of the support block, it is beneficial to increase the friction between the support block and the central armrest, so as to better support the connecting parts. At the same time, the provision of an anti-slip layer on the outer surface of the twist block facilitates the rotation of the threaded rod by better twisting the twist block, thereby adjusting the position of the support block.

[0017] The utility model is further configured such that the outer surface of the first socket is fixedly connected to a limiting plate.

[0018] By adopting the above technical solution, by providing a limiting plate on the outer surface of the first socket, the limiting plate can prevent the first socket from being completely received into the cavity. Therefore, when the first socket is used, the first socket exposed outside the connecting block can be pulled to facilitate use by the rear passengers.

[0019] In summary, the utility model mainly has the following beneficial effects:

[0020] The utility model inserts the plug at the bottom of the connecting piece into the cigarette lighter, so that the connecting piece is connected to the power supply, and then the slider slides in the slide groove, so that the distance between a group of connecting blocks can be adjusted, so that it can better conform to the width of the central armrest of the car, and it is convenient for the connecting blocks to be close to both sides of the central armrest. At the same time, when the rear personnel use the car charger, they can pull the first socket on one side of the connecting block, so that the first socket drives the data line to move, which is beneficial to adjust the position of the first socket to make it close to the rear passengers of the car, so that the rear passengers can use the car charger for charging, thereby improving the use of the car charger by the rear passengers of the car.
