Description

Technical Field

[0001] This utility model relates to the field of vehicle charger technology, and in particular to a vehicle dual USB charger. Background Technology

[0002] A dual USB car charger is a device specifically designed for use in vehicles. It draws power from the car's cigarette lighter socket or a 12V power outlet, allowing two electronic devices to be charged simultaneously. It typically features two USB ports, enabling the connection and charging of two devices at the same time, such as smartphones, tablets, GPS devices, and Bluetooth headsets.

[0003] Most existing dual USB car chargers do not have anti-loosening features. This means that during driving, the USB connector may become loose at the connection point between the USB connector and the car charger due to vehicle vibration or sudden dragging, resulting in poor contact or even the USB connector detaching from the charger, causing charging interruption and reducing the charging efficiency of the dual USB car charger.

[0004] Therefore, it is necessary to provide a vehicle-mounted dual USB charger to solve the above-mentioned technical problems. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a dual USB in-vehicle charger.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a vehicle-mounted dual USB charger, including a charging base, two hollow strips fixedly connected to the top of the charging base, two openings on both sides of each hollow strip, limit rods fixedly connected to both sides of the inner wall of each hollow strip, a pushing component provided on the outer surface of each limit rod, a clamping frame provided on one side of the pushing component, a telescopic component one provided on one side of the inner wall of the clamping frame, a rubber plate provided on one side of the telescopic component one, a telescopic component two provided at the bottom of the inner wall of the clamping frame, a rubber block provided at the bottom of the telescopic component two, an inclined surface provided on the side of the rubber block away from the rubber plate, a protective component provided inside the clamping frame, two USB ports provided on the top of the charging base, and a vehicle-mounted interface provided at the bottom of the charging base.

[0007] By setting up a push component and cooperating with two limit rods, the back-and-forth clamping frames can be moved away from each other. After the USB connector is inserted into the USB port, the push component can be released and the rubber plate and rubber block can be used to limit and clamp the outside and top of the USB connector using telescopic component one and telescopic component two, so as to prevent the USB connector from becoming loose.

[0008] As a further description of the above technical solution:

[0009] The pushing assembly includes a pushing bar slidably connected to the outer surface of the limiting rod, and two springs are fixedly connected to the surface of the pushing bar.

[0010] By setting spring one, the elastic force of spring one can be used to bring the two clamping frames closer together after the push bar is released.

[0011] As a further description of the above technical solution:

[0012] Both ends of the push bar have two opposing openings, and the end of the push bar near the USB interface is fixedly connected to the back of the clamping frame.

[0013] As a further description of the above technical solution:

[0014] The telescopic component includes a limiting post and a spring. One end of the limiting post and one side of the spring are fixedly connected to the back of the rubber plate.

[0015] By setting spring two and limit post one, when the rubber plate comes into contact with the outside of the USB connector, the rubber plate squeezes spring two and pushes limit post one to move outward. At this time, the elastic force of spring two can make the rubber plate fit tightly against the outside of the USB connector.

[0016] As a further description of the above technical solution:

[0017] One end of the second spring is fixedly connected to one side of the inner wall of the clamping frame.

[0018] As a further description of the above technical solution:

[0019] The telescopic component two includes a limiting post two and two springs three. The bottom ends of the limiting post two and the bottom ends of the springs three are fixedly connected to the top of the rubber block.

[0020] By setting spring three and limit post two, when the rubber block contacts the top of the USB connector, the rubber block squeezes spring three and pushes limit post two outward. At this time, the elastic force of spring three can make the rubber block fit tightly against the top of the USB connector.

[0021] As a further description of the above technical solution:

[0022] The top end of the spring is fixedly connected to the top of the inner wall of the clamping frame.

[0023] As a further description of the above technical solution:

[0024] The protective component includes a sealing strip and two sealing rings. The sealing strip is embedded in one side of the clamping frame, and the two sealing rings are respectively fixedly connected to the top and one side of the inner wall of the clamping frame.

[0025] By setting a sealing strip and two sealing rings, external dust and moisture can be prevented from entering the interior of the clamping frame through the gap between the two clamping frames and the gap between the connection between the first and second limiting posts and the clamping frame after the two clamping frames are attached to each other.

[0026] This utility model has the following beneficial effects:

[0027] 1. Compared with existing technologies, this vehicle-mounted dual USB charger, through the combined use of a port, limiting rod, pushing component, clamping frame, telescopic component one, rubber plate, telescopic component two, rubber block, and inclined surface, can clamp and limit the external and top of the USB connector, preventing the USB connector from becoming loose due to vehicle vibration or dragging, preventing poor contact or USB connector detachment, ensuring uninterrupted charging, and improving the charging efficiency of the vehicle-mounted dual USB charger.

[0028] 2. Compared with existing technologies, this vehicle dual USB charger, through the combined use of structures such as limiting rods, pushing components, clamping frames and protective components, can seal and protect the two USB ports without using the vehicle dual USB charger, preventing dust, moisture and other external debris from entering the ports, preventing damage to the ports, and improving the service life of the USB ports and the vehicle charger.

[0035] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0036] Reference Figure 1-4 This utility model provides a dual-USB car charger: It includes a charging base 1, with two hollow strips 2 fixedly connected to the top of the charging base 1. Two openings 3 are provided on both sides of each hollow strip 2. Limiting rods 4 are fixedly connected to both sides of the inner wall of each hollow strip 2. A pushing component is provided on the outer surface of the limiting rods 4. A clamping frame 5 is provided on one side of the pushing component. A telescopic component one is provided on one side of the inner wall of the clamping frame 5. A rubber plate 6 is provided on one side of the telescopic component one. A telescopic component two is provided at the bottom of the inner wall of the clamping frame 5. A rubber block 7 is provided at the bottom of the telescopic component two. An inclined surface 8 is provided on the side of the rubber block 7 away from the rubber plate 6. A protective component is provided inside the clamping frame 5. Two USB ports are provided on the top of the charging base 1. The bottom of the charging base 1 has a vehicle interface 10 and two ports 3 symmetrically arranged around the center of the hollow strip 2. The rubber block 7 is located in front of the rubber plate 6 and above the center of the rubber plate 6. The protective component is used to prevent external dust and moisture from entering the charger through the USB interface 9 and causing damage to the charger. By setting the push component and cooperating with the two limit rods 4, the back and forth clamping frames 5 can be moved away from each other. After the USB connector is inserted into the USB interface 9, the push component is released and the first and second telescopic components are used to limit and clamp the outside and top of the USB connector, preventing the USB connector from becoming loose.

[0037] The pushing assembly includes a pushing strip 11 that is slidably connected to the outer surface of the limiting rod 4. Two springs 12 are fixedly connected to the surface of the pushing strip 11. Both ends of the pushing strip 11 pass through two opposing through-holes 3. The end of the pushing strip 11 near the USB interface 9 is fixedly connected to the back of the clamping frame 5. One end of each of the two springs 12 is fixedly connected to one side of the inner wall of the hollow strip 2. By setting the springs 12, after the pushing strip 11 is released, the elastic force of the springs 12 can be used to bring the two clamping frames 5 closer to each other.

[0038] The telescopic assembly includes a limiting post 13 and a spring 14. One end of the limiting post 13 and one side of the spring 14 are fixedly connected to the back of the rubber plate 6. One end of the spring 14 is fixedly connected to one side of the inner wall of the clamping frame 5. The spring 14 is located outside the limiting post 13, and one end of the limiting post 13 slides through to the outside of the clamping frame 5. By setting the spring 14 and the limiting post 13, when the rubber plate 6 contacts the outside of the USB connector, the rubber plate 6 squeezes the spring 14 and pushes the limiting post 13 outward. At this time, the elastic force of the spring 14 can make the rubber plate 6 fit tightly against the outside of the USB connector.

[0039] The telescopic component two includes a limiting post two 15 and two springs three 16. The bottom ends of the limiting post two 15 and the springs three 16 are fixedly connected to the top of the rubber block 7. The top ends of the springs are fixedly connected to the top of the inner wall of the clamping frame 5. The two springs three 16 are symmetrical about the center of the limiting post two 15, and the top ends of the limiting post two 15 slide through to the top of the clamping frame 5. By setting the springs three 16 and the limiting post two 15, when the rubber block 7 contacts the top of the USB connector, the rubber block 7 squeezes the springs three 16 and pushes the limiting post two 15 outward. At this time, the elastic force of the springs three 16 can make the rubber block 7 fit tightly against the top of the USB connector.

[0040] The protective assembly includes a sealing strip 18 and two sealing rings 17. The sealing strip 18 is embedded in one side of the clamping frame 5, and the two sealing rings 17 are fixedly connected to the top and one side of the inner wall of the clamping frame 5, respectively. The two sealing rings 17 are located at the connection between the first limiting post 13 and the second limiting post 15 and the clamping frame 5, respectively. The sealing strip 18 is U-shaped and extends to the surface of one side of the clamping frame 5. By setting the sealing strip 18 and the two sealing rings 17, after the two clamping frames 5 are fitted together, external dust and moisture can be prevented from entering the interior of the clamping frame 5 through the gap between the two clamping frames 5 and the gap between the first limiting post 13 and the second limiting post 15 and the clamping frame 5.

[0041] Working principle: In use, first pull the two push bars 11 outwards, causing them to move the two clamping frames 5 away from each other and compress the spring 12 until the USB interface 9 is fully exposed. Then insert the USB connector into the USB interface 9. Afterwards, release the two push bars 11, and under the elastic force of the two springs 12, the two clamping frames 5 will move closer together until the outside of the USB connector enters the interior of the clamping frame 5. At this point, the spring 12 will continue to move the clamping frame 5. However, as the clamping frame 5 moves, the outside of the USB connector will first contact the rubber block 7. When the inclined plane 8 contacts, the USB connector will push the rubber block 7 upward and squeeze the spring 16 until it no longer contacts the inclined plane 8. At this time, the elastic force of the spring 16 will push the rubber block 7 to fit against the top of the USB connector, thereby limiting and clamping the top of the USB connector. Then the USB connector will contact the rubber plate 6, causing the rubber plate 6 to squeeze the spring 14 and drive the limiting post 13 to move outward. At this time, the elastic force of the spring 14 will push the rubber plate 6 to fit tightly against the outside of the USB connector, thereby limiting and clamping the outside of the USB connector.

[0042] When it is necessary to seal and protect the two USB ports 9, first pull the two push bars 11 outward to move the two clamping frames 5 away from each other and squeeze the spring 12. Then release the two push bars 11 and under the elastic force of the two springs 12, make the two clamping frames 5 come closer to each other. At this time, since there is no USB connector to block it, several springs 12 will push the two clamping frames 5 to stick together, thus forming a closed space. With the use of sealing ring 17 and sealing strip 18, dust and moisture can be prevented from entering the clamping frame 5.

[0043] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
