Description

Technical Field

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

[0002] In modern society, cars have become an essential tool for daily travel, and their ownership continues to rise. At the same time, portable electronic devices such as mobile phones, tablets, and GPS navigators have become deeply integrated into people's lives, becoming an indispensable part. While these electronic devices are powerful, their battery life is often insufficient due to limitations in battery technology. Therefore, the demand for charging electronic devices in vehicles is growing, making car chargers increasingly important as key devices to meet this need.

[0003] A typical safe car charger consists of a housing, a protective mechanism, and a charging mechanism. The housing uses a sealed design to isolate external dust and moisture, while also fixing the position of internal components and providing physical protection for the overall structure. The protective top cover serves as the top protective structure of the housing, shielding the charging interface and internal components from direct impacts from external bumps and falling objects. The charging mechanism uses an internal transformer to convert the vehicle voltage into a standard voltage suitable for electronic devices, and then outputs a stable current through the interface to achieve efficient charging of devices such as mobile phones and tablets.

[0004] In existing technologies, some devices allow dust and debris from inside the vehicle to easily enter the interface during vehicle operation. Long-term accumulation can lead to poor contact, affecting charging efficiency and even causing charging malfunctions. Furthermore, when the car charger is not in use, external water droplets or liquids can easily splash into the interface, causing short circuits and other safety hazards. This can damage the charger itself and adversely affect the vehicle's electrical system. Moreover, most of these devices only provide basic charging functions and cannot meet the increasingly diverse needs of users. Therefore, a safer car charger is proposed to address these issues.

[0010] As a further description of the above technical solution:

[0011] The bottom of the supporting arc block is supported on the top outer side of the top plate, and the outside of the reset snap ring is supported on the outside of the connecting plate.

[0012] As a further description of the above technical solution:

[0013] The charging mechanism includes a controller, which is externally fixedly connected to the inside of the housing. A device frame is fixedly connected to the top of the controller. Two interfaces a are fixedly connected to the top outer side of the device frame, and two interfaces b are fixedly connected to the top outer side of the device frame. A rotating groove is fixedly connected to the top of the device frame.

[0014] As a further description of the above technical solution:

[0015] The mounting assembly includes a locking block, which is externally slidably connected to the inside of the housing. A return spring is sleeved inside the locking block. The housing has slots on both external sides. An elastic contact is slidably connected to the bottom of the housing. The return spring is externally supported inside the housing.

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

[0017] The outer sides of the plurality of locking teeth are respectively engaged with the inner sides of the plurality of tooth grooves, and the adjacent sides of the plurality of locking teeth are slidably connected inside the annular groove;

[0023] 1. In this utility model, multiple locking teeth engage with the toothed grooves on the outside of the locking ring, and the locking teeth slide in the annular groove on the outside of the locking ring, allowing the locking ring to rotate stably within the mounting ring and be positioned at a specific angle. The top plate rotates within the rotating groove on the top of the equipment frame via a rotating column, causing the locking ring to rotate. Simultaneously, the rubber layer moves with the top plate, covering interfaces a and b, protecting the interfaces from dust contamination. The cutting notch and the cone nail allow for cutting the seat belt using the cutting notch and breaking the car window glass using the cone nail, facilitating emergency escape. Thus, the vehicle charger achieves stable operation while also providing interface protection and emergency escape assistance, improving the safety, convenience, and multi-functionality of the product.

[0024] 2. In this utility model, the support base and the rotating base are rotatably connected, allowing the connecting plate to rotate and be pulled out flexibly. This, in turn, drives the support arc block to adjust its position to adapt to the state of the top plate. The support arc block contacts the outer side of the top of the top plate. When the connecting plate deflects, the reset spring will generate elastic force, which is transmitted to the top plate through the connecting plate. This can reliably support the top plate and ensure its positional stability during operation, thus solving the problem that the top plate is difficult to automatically reset after rotation or being pulled out and that the support stability is insufficient.

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.

[0033] Reference Figure 1 , Figure 2 and Figure 5 The present invention provides an embodiment of a safe vehicle charger, comprising a housing 1, which serves as the basic frame of the entire vehicle charger and plays a role in accommodating, fixing and protecting all internal components. A friction ring 2 is fixedly connected to the top outer side of the housing 1, which increases the friction force when holding or operating the top of the charger. A mounting ring 3 is fixedly connected to the top of the housing 1, which provides a fixed mounting position and is a key component connecting the housing 1 and the multi-functional mechanism 6. Multiple connecting mechanisms 4 are provided on the top of the friction ring 2. A charging mechanism 5 is provided inside the housing 1, and a multi-functional mechanism 6 is provided outside the mounting ring 3.

[0034] The multi-functional mechanism 6 includes multiple locking teeth 61, which engage with the grooves 63 on the locking ring 62 to position the locking ring 62 at different rotation angles and restrict its free rotation. The multiple locking teeth 61 are externally fixedly connected to the interior of the mounting ring 3. The locking ring 62 is slidably connected to adjacent sides of the locking teeth 61. The locking ring 62 connects the mounting ring 3 and the top plate 65, enabling the rotation of the top plate 65 and achieving positioning through engagement with the locking teeth 61. The locking ring 62 has multiple grooves 63 on its exterior, which engage with the locking teeth 61 to provide locking points for positioning the locking ring 62, allowing it to be fixed at a specific angle. The locking ring 62 also has an annular groove 64 on its exterior, providing a sliding track for the locking teeth 61 to ensure smooth rotation of the locking ring 62 and to guide and limit the locking teeth 61. The top of the locking ring 62... A top plate 65 is fixedly connected. The top plate 65 serves as the operating and functional platform of the multi-functional mechanism 6, supporting the cutting opening 68 and the conical nail 69. At the same time, the position can be adjusted by rotating the locking ring 62. The top of the top plate 65 is fixedly connected to the cutting opening 68, which is used to cut the seat belt in an emergency. The top of the cutting opening 68 is fixedly connected to the conical nail 69, which is used to break the car window glass in an emergency. The bottom of the top plate 65 is fixedly connected to the rotating column 66, which cooperates with the rotating groove 55 in the charging mechanism 5 to provide a rotation axis for the rotation of the top plate 65 and the locking ring 62. The bottom of the top plate 65 is fixedly connected to the rubber layer 67. When the top plate 65 covers the interface a and the interface b, the rubber layer 67 plays a role in sealing, dustproofing and buffering, protecting the interface from damage. The mounting components 7 are slidably connected to both sides of the inside of the housing 1.

[0035] Mounting component 7 includes a locking block 71, which secures and fixes the housing 1 to prevent loosening or falling off during use. The outer side of the locking block 71 is slidably connected to the inside of the housing 1. A return spring 72 is fitted inside the locking block 71, providing elastic restoring force so that the locking block 71 can automatically pop out and remain in the locked position. The outer sides of the housing 1 are provided with locking slots 73, which provide locking positions. The bottom of the housing 1 is slidably connected with an elastic contact 74, which enables electrical connection between the charger and the car cigarette lighter interface to ensure stable power transmission. The outer side of the return spring 72 is supported inside the housing 1. The outer sides of multiple locking teeth 61 are respectively locked inside multiple tooth grooves 63. The adjacent sides of multiple locking teeth 61 are slidably connected inside the annular groove 64. The outer side of the locking ring 62 is rotatably connected inside the mounting ring 3. The bottom outer side of the top plate 65 is supported on the top of the mounting ring 3.

[0036] Reference Figure 1 , Figure 3 and Figure 4The connecting mechanism 4 includes a support base 41, which provides an installation position for the rotating base 42, the reset spring 44, etc. The bottom of the support base 41 is fixedly connected to the top of the mounting ring 3. The rotating base 42 is rotatably connected to the outside of the support base 41. The rotating base 42 connects the support base 41 and the connecting plate 43, realizing the rotation function of the connecting plate 43. The connecting plate 43 is fixedly connected to the outside of the rotating base 42. The connecting plate 43 transmits force and connects the rotation of the rotating base 42 with the support arc block 45 and the reset spring 44, realizing the support and reset of the top plate 65. Force transmission: A reset spring 44 is sleeved on the outside of the support base 41. The reset spring 44 provides a reset elastic force to the connecting plate 43. When the top plate 65 rotates, a restoring force can be applied to the top plate 65 through the connecting plate 43 to help the top plate 65 return to its initial position. Supporting arc blocks 45 are fixedly connected to adjacent sides of the connecting plate 43. The supporting arc blocks 45 contact the outer top of the top plate 65 and provide support for the top plate 65. The bottom of the supporting arc blocks 45 is supported on the outer top of the top plate 65, and the outside of the reset spring 44 is supported on the outside of the connecting plate 43.

[0037] Reference Figures 1 to 3 The charging mechanism 5 includes a controller 51, which processes the input vehicle power supply and regulates parameters such as charging voltage and current to ensure a safe and stable charging process. The controller 51 is externally and fixedly connected to the inside of the housing 1. A device frame 52 is fixedly connected to the top of the controller 51. The device frame 52 provides mounting positions for interfaces a, b, and slots 55, integrating these components into a single charging interface module. Two interfaces a53 are fixedly connected to the top outer side of the device frame 52. Interface a53 provides a charging interface type for connecting corresponding charging equipment to achieve power transfer. The device frame 52 has two fixed interfaces b54 on its top outer side. Interface b54 provides another type of charging interface, which is used in conjunction with interface a to increase the types of interfaces of the charger and adapt to the charging needs of more devices. The top of the device frame 52 has a fixed rotating groove 55, which cooperates with the rotating post 66 to provide a rotating track for the rotating post 66, ensuring that the rotating post 66 rotates smoothly, thereby ensuring the stable rotation of the top plate 65 and the snap ring 62. The external rotating connection of the rotating post 66 is rotatably connected to the inside of the rotating groove 55. The bottom of the rubber layer 67 is supported on the top of interface a53 and the bottom of the rubber layer 67 is supported on the top of interface b54.

[0038] Working principle: When in use, first insert the elastic contact 74 at the bottom of the housing 1 into the car cigarette lighter interface. The locking blocks 71 on both sides inside the housing 1 are locked into the corresponding positions under the action of the return spring 72, and the housing 1 is fixed in conjunction with the locking groove 73. The friction ring 2 on the outer side of the top of the housing 1 is easy to grip and operate. The mounting ring 3 on the top provides the mounting base for the multi-functional mechanism 6. Multiple locking teeth 61 are fixed inside the mounting ring 3 and engage with the tooth groove 63 on the outside of the locking ring 62. The ring groove 64 on the outside of the locking ring 62 allows the locking teeth 61 to slide. The top plate 65 rotates in the rotating groove 55 on the top of the equipment frame 52 through the rotating column 66, which drives the locking ring 62 to rotate in the mounting ring 3. The rubber layer 67 moves with the top plate 65, covering or exposing the interface a and interface b on the equipment frame 52.

[0039] In the connecting mechanism 4, the support base 41 is fixed on the top of the mounting ring 3, and the rotating base 42 rotates outside the support base 41, driving the connecting plate 43 and the supporting arc block 45 to move. The supporting arc block 45 supports the top plate 65, and the reset snap ring 44 outside the support base 41 deforms and stores force when the connecting plate 43 rotates.

[0040] During charging, the elastic contact 74 introduces the vehicle power into the controller 51 inside the housing 1. After processing the electrical energy, the controller 51 outputs it through interface a and interface b to charge external devices. In an emergency, the top plate 65 is rotated to position the cutting notch 68 or the cone nail 69 in a suitable position. The cutting notch 68 is used to cut the seat belt, and the cone nail 69 is used to break the window glass. At this time, the engagement of the locking teeth 61 and the groove 63 ensures the stability of the top plate 65.

[0041] 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.
