Description

Technical Field

[0001] The present invention relates to the field of vehicle facilities, and particularly to a vehicle USB charger. Background Art

[0002] A vehicle is a non-railborne vehicle driven by power and having 4 or more wheels, mainly used for carrying people or goods. Among them, the vehicle USB charger is widely used due to its convenient charging and other characteristics. In the existing vehicle USB charger, during long-term use, the USB connector of the charging cable and the USB interface on the USB charger are prone to looseness, resulting in poor contact between the USB connector of the charging cable and the USB interface on the USB charger under the influence of vehicle driving bumps, seriously affecting the stability during charging. At the same time, when not charging, the charging port of the charging cable often falls to the bottom of the vehicle and is accidentally stepped on and damaged by people getting on and off the vehicle, and the protection performance of the charging cable is poor. Summary of the Invention

[0003] The purpose of the present invention is to solve the deficiencies in the background art and propose a vehicle USB charger.

[0004] To achieve the above purpose, the technical solution adopted by the present invention is: a vehicle USB charger, including a charger body and a charger connector connected to the lower end of the charger body. One side edge of the upper end surface of the charger body extends with a connecting rod, and the other side edge of the upper end surface of the charger body extends with a support rod. The upper end of the connecting rod is rotatably installed with a protection plate, and the protection plate is fixed to the support rod by magnetism. A limiting member extends on the upper end surface of the protection plate, a wire-dragging cross bar is installed on the outer side of the support rod, a wire-fixing member is installed on the outer side of the wire-dragging cross bar, and a wire-pressing member extends in the middle of the upper end surface of the charger body.

[0005] Preferably, a plurality of groups of USB interfaces are arranged in a linear array in the middle of the upper end surface of the charger body. A connection hole is formed through the upper end surface of the wire-dragging cross bar, and the outer surface of the support rod is fixed inside the connection hole. The limiting member includes a plurality of groups of limiting frames extending in a linear array on the upper end surface of the protection plate. The shape of the limiting frame is concave, and first rubber pads extend from the front and rear end faces of the limiting frame.

[0006] Preferably, a groove body is inlaid at the upper end of the connecting rod. A connecting convex block extends from one side edge of the lower end surface of the protection plate, and the connecting convex block is located inside the groove body. Bearing bodies are inlaid through the front end faces of the groove body and the connecting convex block.

[0007] Preferably, a fixing post extends from the other edge of the lower end surface of the protection plate. A lower magnet is coaxially embedded at the upper end of the support rod, and an upper magnet is coaxially embedded at the lower end of the fixing post. The lower magnet is adsorbed to the upper magnet, and the fixing post is located on the side of the connecting bump.

[0008] Preferably, the wire fixing member includes a plurality of fixing rings fixedly installed on the outer side of the wire dragging cross bar. A wire fixing clamping ring is embedded on the upper end surface of the fixing ring. Two wire guiding plates are symmetrically and obliquely embedded at the upper end of the wire fixing clamping ring. The wire guiding plates are integrally formed with the wire fixing clamping ring. A second rubber pad is arranged on the upper end surface of the wire guiding plates. A rubber ring is arranged inside the wire fixing clamping ring, and the rubber ring is integrally formed with the second rubber pad.

[0009] Preferably, the wire pressing member includes a seat plate extending from the rear edge of the upper end surface of the charger body. A pulling column is elastically installed through the front end surface of the seat plate in a fitting manner. A connecting seat is embedded at the front end of the pulling column. A guiding column is embedded through the edge of the front end surface of the connecting seat, and a pressing and fixing frame is installed on the side surface of the guiding column.

[0010] Preferably, a connecting column extends from the side surface of the pressing and fixing frame, and the end of the connecting column is fixedly connected to the outer surface of the guiding column. A bearing frame extends from the rear of the USB interface on the upper end surface of the charger body. The pressing and fixing frame penetrates through the front end surface of the bearing frame in a fitting manner. A guiding ring extends from the side surface of the bearing frame, and the outer surface of the guiding column fits into the inner outer surface of the guiding ring. The connecting column is located behind the guiding ring at the same horizontal line.

[0011] Preferably, an adapter plate is embedded at the rear end of the pulling column. A pull ring extends from the middle of the rear end surface of the adapter plate, and the adapter plate is integrally formed with the pull ring. A circular hole is penetrated through the front end surface of the seat plate, and the pulling column fits into the inside of the circular hole. A spring body is wound around the outer side of the pulling column, and the spring body is located between the rear end surface of the connecting seat and the front end surface of the seat plate. A limiting through hole is penetrated through the front end surface of the bearing frame, and the outer surface of the pressing and fixing frame fits into the inner outer surface of the limiting through hole.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] 1. By means of the arranged wire pressing member, the connecting plate can be pulled to drive the guide post to slide in the guide ring. At the same time, the pressing and fixing frame slides in the limiting through hole on the bearing frame, so that the pressing and fixing frame moves away from directly above the USB interface. Subsequently, the USB connector of the charging cable is inserted into the USB interface, and the connecting plate is released. Then, the pressing and fixing frame resets under the pushing action of the spring body and presses on the USB connector of the charging cable to tightly press the USB connector of the charging cable in the USB interface, so as to avoid the looseness between the USB connector of the charging cable and the USB interface during long-term use and the poor contact between the USB connector of the charging cable and the USB interface under the influence of vehicle driving bumps, thereby improving its charging stability.

[0014] 2. By means of the arranged wire fixing member, when not charging, the wire at the charging port of the charging cable can be placed between two groups of wire plates and pressed downward. At this time, the second rubber pad deforms, enabling the wire to enter the wire fixing snap ring under the guidance of the two groups of wire plates. Meanwhile, the rubber ring deforms under the action of the wire and generates a reaction force to clamp and fix the wire, so that the charging port of the charging cable can be suspended and fixed on the towing cross bar, avoiding the phenomenon that the charging port of the charging cable drops and is damaged by being stepped on, thereby improving the protection performance of the charging cable.

[0015] 3. By means of the arranged limiting member, when charging, an object to be charged such as a power bank can be placed between multiple groups of limiting frames for placement, enabling the object to be charged to be placed above the charger body. This can effectively reduce the space occupied in the vehicle during charging and improve its practicality. Moreover, under the protection of the protective plate, it can avoid the phenomenon that the wiring part is damaged by being impacted by external objects after the USB connector of the charging cable is inserted into the USB interface, further improving the protection of the charging cable. And when plugging and unplugging the USB connector of the charging cable, the lower magnet and the upper magnet adsorbed together can be separated, enabling the protective plate to flip and move away from directly above the charger body, facilitating the plugging and unplugging operation of the charging cable.

Specific embodiments

[0022] The following description is used to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments in the following description are only examples, and those skilled in the art can think of other obvious variations.

[0023] As Figures 1 - 5 shown, a USB charger for a vehicle includes a charger body 1 and a charger connector 29 connected to the lower end of the charger body 1. A connecting rod 2 extends from one side edge of the upper end surface of the charger body 1, and a support rod 3 extends from the other side edge of the upper end surface of the charger body 1. A protection plate 4 is rotatably installed at the upper end of the connecting rod 2, and the protection plate 4 is fixed to the support rod 3 by magnetism. A limiting member extends from the upper end surface of the protection plate 4. A wire-dragging cross bar 5 is installed outside the support rod 3, and a wire-fixing member is installed outside the wire-dragging cross bar 5. A wire-pressing member extends from the middle of the upper end surface of the charger body 1. The charger connector 29 can connect the charger body 1 to the power source on the vehicle. Since the charger body 1 and the charger connector 29 connected to the lower end of the charger body 1 are prior arts, and connecting the charger body 1 to the power source on the vehicle is a common connection method in life, so no more details will be given here. The wire-dragging cross bar 5 plays a bearing role, and the connecting rod 2 plays a role in connecting the protection plate 4.

[0024] In the middle of the upper end face of the charger body 1, there are multiple groups of USB interfaces 30 arranged in a linear array. A connection hole 32 is penetrated and opened on the upper end face of the wire-dragging cross bar 5. The outer surface of the support rod 3 is fixed inside the connection hole 32. The limiting member includes multiple groups of limiting frames 6 extending in a linear array on the upper end face of the protection plate 4. The shape of the limiting frame 6 is concave. One-piece rubber pads 7 extend from the front and rear end faces of the limiting frame 6. Through the provided USB interfaces 30, the charging cable can be connected to the charger body 1. The connection hole 32 can limit the support rod 3 to fix the support rod 3 and the wire-dragging cross bar 5 together. The protection plate 4 plays a role in bearing and can block foreign objects at the same time. After the USB connector of the charging cable is inserted into the USB interface 30, the wiring part will not be damaged by being impacted by foreign objects. When charging, after placing the object to be charged, such as a power bank, between multiple groups of limiting frames 6, the one-piece rubber pads 7 will deform under the action of the object to be charged and generate a reaction force to clamp and fix the object to be charged, so as to improve the fixing force on the object to be charged.

[0025] A groove body 20 is inlaid at the upper end of the connecting rod 2. A connecting convex block 21 extends from one side edge of the lower end face of the protection plate 4. The connecting convex block 21 is located inside the groove body 20. Bearing bodies 22 are penetrated and inlaid on the front end faces of the groove body 20 and the connecting convex block 21. Through the provided groove body 20, the connecting convex block 21 can be limited. The connecting convex block 21 plays a connecting role. The bearing bodies 22 can rotatably connect the groove body 20 and the connecting convex block 21 together, so that the protection plate 4 can be stably turned over.

[0026] A fixing column 27 extends from the other side edge of the lower end face of the protection plate 4. A lower magnet 26 is coaxially inlaid at the upper end of the support rod 3. An upper magnet 28 is coaxially inlaid at the lower end of the fixing column 27. The lower magnet 26 and the upper magnet 28 are adsorbed to each other. The fixing column 27 is located on the side of the connecting convex block 21. Through the provided fixing column 27, the upper magnet 28 can be fixed. The upper magnet 28 and the lower magnet 26 are adsorbed to each other, which can fix the protection plate 4 so that the protection plate 4 can be fixed on the support rod 3, and the support rod 3 can support the protection plate 4.

[0027] The wire fixing member includes multiple groups of fixing rings 8 fixedly installed on the outer side of the wire towing cross bar 5. A wire fixing clamping ring 23 is inlaid on the upper end surface of the fixing ring 8. Two groups of wire guiding plates 24 are symmetrically and obliquely inlaid at the upper end part of the wire fixing clamping ring 23. The wire guiding plates 24 are integrally formed with the wire fixing clamping ring 23. A second rubber pad 25 is arranged on the upper end surface of the wire guiding plates 24. A rubber ring 33 is arranged inside the wire fixing clamping ring 23. The rubber ring 33 is integrally formed with the second rubber pad 25. The fixing ring 8 can fix the wire fixing clamping ring 23 and the wire towing cross bar 5 together. The wire fixing clamping ring 23 functions to fix the wires at the charging port of the charging wire. The wire guiding plates 24 can guide the wires at the charging port of the charging wire so that the wires at the charging port of the charging wire can enter the wire fixing clamping ring 23. The second rubber pad 25 can deform when the wires at the charging port of the charging wire are placed between the two groups of wire guiding plates 24 and pressed downwards, so as to ensure that the wires at the charging port of the charging wire can smoothly pass between the two groups of wire guiding plates 24. The rubber ring 33 will deform under the action of the wires after the wires enter the wire fixing clamping ring 23 and generate a reaction force to clamp and fix the wires.

[0028] The wire pressing member includes a seat plate 9 extending at the rear edge of the upper end surface of the charger body 1. A pulling column 10 is elastically installed through the front end surface of the seat plate 9 in a fitting manner. A connecting seat 14 is inlaid at the front end part of the pulling column 10. A guiding column 19 is inlaid through the edge of the front end surface of the connecting seat 14. A pressing and fixing frame 16 is installed on the side surface of the guiding column 19. The seat plate 9 can carry the pulling column 10. The pulling column 10 can pull the connecting seat 14. The connecting seat 14 can connect the guiding column 19.

[0029] A connecting column 17 extends from the side surface of the pressing and fixing frame 16. The end of the connecting column 17 is fixedly connected to the outer surface of the guiding column 19. A bearing frame 15 extends behind the USB interface 30 on the upper end surface of the charger body 1. The pressing and fixing frame 16 passes through the front end surface of the bearing frame 15 in a fitting manner. A guiding ring 18 extends from the side surface of the bearing frame 15. The outer surface of the guiding column 19 fits on the inner outer surface of the guiding ring 18. The connecting column 17 is located behind the guiding ring 18 at the same horizontal line. The connecting column 17 can fix the guiding column 19 and the pressing and fixing frame 16 together. The pressing and fixing frame 16 can tightly fix the USB connector of the charging wire. The bearing frame 15 can improve the pressing force of the pressing and fixing frame 16. The guiding ring 18 can limit the guiding column 19. The cooperation between the guiding column 19 and the guiding ring 18 can ensure that the pressing and fixing frame 16 moves in a straight line when moving.

[0030] The rear end of the pulling column 10 is inlaid with an adapter plate 11. In the middle of the rear end face of the adapter plate 11, a pull ring 12 extends. The adapter plate 11 and the pull ring 12 are integrally formed. A round hole is penetratingly opened on the front end face of the seat plate 9. The pulling column 10 fits inside the round hole. A spring body 13 is wound around the outer side of the pulling column 10. The spring body 13 is located between the rear end face of the connecting seat 14 and the front end face of the seat plate 9. A limiting through hole 31 is penetratingly opened on the front end face of the bearing frame 15. The outer surface of the pressing and fixing frame 16 fits on the inner outer surface of the limiting through hole 31. By providing the adapter plate 11, the pulling column 10 can be connected. The pull ring 12 can facilitate the grasping of the adapter plate 11. The round hole can limit the pulling column 10. The spring body 13 can push the connecting seat 14, and then push the guiding column 19, so that the pressing and fixing frame 16 connected to the guiding column 19 can be reset to tightly fix the USB connector of the charging cable. The limiting through hole 31 plays a role in limiting the pressing and fixing frame 16.

[0031] During use, the user pulls the adapter plate 11 to drive the guiding column 19 to slide in the guiding ring 18. At the same time, the pressing and fixing frame 16 slides in the limiting through hole 31 on the bearing frame 15, so that the pressing and fixing frame 16 is separated from directly above the USB interface 30. Then the user inserts the USB connector of the charging cable into the USB interface 30 and releases the adapter plate 11, so that the pressing and fixing frame 16 is reset under the pushing action of the spring body 13 and presses on the USB connector of the charging cable to tightly press the USB connector of the charging cable in the USB interface 30. Then insert the charging port of the charging cable into the object to be charged for charging. When charging, place the object to be charged, such as a power bank, between multiple groups of limiting frames 6. At this time, the first rubber pad 7 on the limiting frame 6 deforms under the action of the object to be charged and generates a reaction force to clamp and fix the object to be charged, so as to place the object to be charged. The object to be charged can be placed above the charger body 1, which can effectively save the space in the vehicle occupied during charging. And during charging, under the protection of the protection plate 4, it can be avoided that after the USB connector of the charging cable is inserted into the USB interface 30, its wiring part is hit by an external object and damaged. After charging is completed, the user can place the wire at the charging port of the charging cable between two wire plates 24 and press down. At this time, the second rubber pad 25 deforms, so that the wire enters the wire fixing clamp ring 23 under the guidance of the two wire plates 24. At the same time, the rubber ring 33 deforms under the action of the wire and generates a reaction force to clamp and fix the wire, so that the charging port of the charging cable can be suspended and fixed on the wire towing cross bar 5, avoiding the phenomenon that the charging port of the charging cable drops and is damaged by being stepped on.
