Description

Technical Field

[0001] The utility model relates to the technical field of chargers, in particular to a vehicle charger which is easy to plug and unplug. Background Art

[0002] With the rapid advancement of technology and the widespread popularity of mobile smart devices, car chargers have evolved into an indispensable part of modern car interiors. They effectively use the vehicle's power supply to charge a variety of electronic devices such as smartphones and tablets, greatly enriching and facilitating the travel experience of drivers and passengers. Traditional car charging solutions generally rely on connecting the charger to the vehicle's cigarette lighter interface. Although this configuration greatly promoted the popularity of car charging in the early days, it gradually revealed some inconveniences in actual applications, especially the frequent plug-in and unplug operations.

[0003] For a long time, the unplugging operation of most car chargers relies on directly manually grabbing the charger body. This method is not only cumbersome to operate, but also easily increases the physical wear between the charger and the vehicle's cigarette lighter interface. It may also cause damage to the charger due to improper use of external force. In some cases, it is even difficult to unplug smoothly, which greatly affects the smoothness of the user experience. In addition, many car models nowadays tend to be precise and compact in interior layout, and the space around the cigarette lighter is often restricted by other on-board equipment or design elements, further aggravating the complexity of the charger plug-in and unplug operation, making this basic demand even more difficult.

[0004] On a deeper level, in order to coordinate with the aesthetic design trend of the car interior, the design of the car charger tends to be extremely compact. Its length and the height protruding from the cigarette lighter socket are carefully reduced to maintain the neatness and visual harmony in the car. However, such a design also brings new challenges: the reduced size greatly compresses the effective gripping area when the user directly pulls out the charger by hand without special auxiliary tools, which increases the difficulty of successfully pulling out the charger from the narrow cigarette lighter hole, thereby reducing the user experience. Utility Model Content

[0005] The problem solved by the utility model is that in order to cater to the overall aesthetic design of the vehicle interior environment, the vehicle charger is usually designed to be relatively compact, and its length and the part protruding from the cigarette lighter socket are intentionally reduced. Although this is conducive to maintaining the cleanliness and harmony of the vehicle interior, it also brings challenges: the reduced size makes it difficult to exert force when directly pulling out the charger by hand without using auxiliary tools due to the limited gripping area, which in turn increases the difficulty of smoothly pulling it out from the cigarette lighter.

[0006] In order to solve the above problems, the utility model provides a pluggable vehicle charger, comprising a shell, a main board and a rebound assembly; the main board and the rebound assembly are respectively arranged in the shell, and the rebound assembly comprises a support tube, a sliding unit and a positioning plate; the outer cylindrical surface of the support tube is fixedly connected to the inner wall of the shell, the sliding unit is slidably arranged in the support tube, and the two ends of the positioning plate are respectively slidably connected to the sliding unit and rotatably connected to the side of the support tube; the sliding unit comprises a slider, a connecting rod and a finger ring; the slider is slidably connected to the shell, and the two ends of the connecting rod are respectively fixedly connected to the top of the slider and rotatably connected to the finger ring.

[0007] Preferably, the sliding block comprises a block body, a first supporting column and a guide groove; the guide groove is provided on a side surface of the block body, and one end of the first supporting column is fixedly connected to the bottom of the block body.

[0008] Preferably, a connecting hole is provided at one end of the connecting rod.

[0009] Preferably, the finger ring is rotatably connected to the connecting hole.

[0010] Preferably, the support tube includes a tube body, a second support column, a positioning baffle and a rebound spring; the two positioning baffles are respectively arranged on both sides of the opening of the tube body, one end of the second support column is arranged at the bottom of the tube body, and the two ends of the rebound spring are respectively mounted on one end of the first support column and the second support column.

[0011] Preferably, the positioning plate includes a connecting plate, a first connecting column, a second connecting column and a bearing; the two ends of the connecting plate are respectively fixedly connected to one end of the first connecting column and the second connecting column, the bearing is sleeved on the other end of the first connecting column, and the bearing is slidably arranged in the guide groove.

[0012] Preferably, the mainboard includes a USB socket, a circuit board, a positive electrode pin and a negative electrode spring; the circuit board is arranged in the shell, the two ends of the circuit board are respectively fixedly connected to the USB socket and the positive electrode pin, the other end of the positive electrode pin passes through one end of the shell, the negative electrode spring is fixedly connected to the circuit board, and the two ends of the negative electrode spring respectively pass through the two sides of the shell.

[0013] Compared with the prior art, the utility model uses the synergistic effect of the sliding unit, the support tube, the positioning plate and the connecting rod in the rebound assembly; when the user needs to unplug the charger, he lightly presses the top of the connecting rod, and this action starts the dynamic process of the rebound assembly: the connecting rod slides down and drives the slider to slide down synchronously. At this time, the guide groove on the slider guides the upper end of the positioning plate to slide along the specific track of the guide groove, so that most of the connecting rod can be hidden inside;

[0014] When the user releases the pressure, the compressed rebound spring releases energy, pushing the slider and the connecting rod to rebound upward. The rise of the connecting rod not only reveals itself, but also drives the position of the finger ring to rise, providing the user with an easy-to-grasp protrusion, thereby easily pulling out the charger.

[0015] In this way, not only the problem of small car chargers being difficult to unplug directly by hand is solved without increasing the external size, but also the smoothness and convenience of the entire operation process is ensured; through the conversion of the internal structure of the rebound component, the gripping area during unplugging is effectively expanded, so that even in the compact in-car environment, the user can complete the plugging and unplugging operation effortlessly, avoiding the difficulty of unplugging due to the limited direct gripping area, and ensuring the comfort and efficiency of the operation.

[0016] Ultimately, the mechanical linkage structural design of the rebound component, material selection, and mainboard circuit management were used to solve the removal problem caused by the miniaturized design. This not only maintains the compactness and beauty of the car charger, but also greatly improves the convenience and safety of operation, providing users with a high-quality charging solution that is both aesthetically pleasing and practical in the car environment, solving the problem of inconvenience in removal caused by size reduction in the past, and achieving a perfect balance between aesthetics and functionality.

It should be understood that the numbers used in this way can be interchanged where appropriate, so that the embodiments of the utility model described herein can be implemented in an order other than those illustrated or described herein.

[0024] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "set", "install", "connect", and "connect" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0025] In the description of this specification, the description with reference to the terms "embodiment", "one embodiment" and "one implementation" etc. means that the specific features, structures, materials or characteristics described in conjunction with the embodiment or implementation are included in at least one embodiment or implementation of the utility model. In this specification, the schematic representation of the above terms does not necessarily refer to the same embodiment or implementation. Moreover, the specific features, structures, materials or characteristics described can be combined in any one or more embodiments or implementations in a suitable manner.

[0026] To solve the above problems, Figure 1 As shown, the embodiment of the utility model provides a pluggable vehicle charger, comprising a housing 1, a main board and a rebound component 2; the main board and the rebound component 2 are respectively arranged in the housing 1, as shown in FIG. Figure 2 As shown, the rebound assembly 2 includes a support tube 3, a sliding unit 4 and a positioning plate 5; the outer cylindrical surface of the support tube 3 is fixedly connected to the inner wall of the outer shell 1, the sliding unit 4 is slidably arranged in the support tube 3, and the two ends of the positioning plate 5 are respectively slidably connected to the sliding unit 4 and rotatably connected to the side of the support tube 3; the sliding unit 4 includes a slider 6, a connecting rod 7 and a finger ring 8; the slider 6 is slidably connected to the outer shell 1, and the two ends of the connecting rod 7 are respectively fixedly connected to the top of the slider 6 and rotatably connected to the finger ring 8.

[0027] It should be noted that the housing 1 is used to support the mainboard and the rebound component 2. The circuit board in the mainboard is connected to the vehicle's cigarette lighter through the positive ejector pin and the negative spring clip to facilitate the transmission of the vehicle's electrical energy to the USB socket. The rebound component 2 is used to press the top of the connecting rod 7 when the vehicle charger needs to be unplugged to make the connecting rod 7 slide down. The sliding movement of the connecting rod 7 drives the slider 6 to slide down. When the slider 6 slides down, the upper end of the positioning plate 5 slides out under the guidance of the guide groove 11 on the slider 6. At this time, the hand releases the pressing of the connecting rod 7, and the compressed rebound spring releases the elastic force to push the slider 6 to slide up. The sliding movement of the slider 6 drives the connecting rod 7 rises, the connecting rod 7 rises and drives the finger ring 8 to rise. At this time, the upper end of the positioning plate 5 enters the bottom of the guide groove 11, and the connecting rod 7 rises and drives the finger ring 8 to rise, so that the hand can pull through the finger ring 8 to drive the vehicle charger to be smoothly pulled out, thereby greatly improving the convenience of use and user experience; the user only needs to simply press and release, and the charger can be easily pulled out by pulling the finger ring 8, without having to fumble around or worry about damaging the cigarette lighter socket. Especially in the case of limited space in the cockpit and inconvenient operation, this design is particularly important to ensure smooth and quick use.

[0028] Secondly, it perfectly solves the problem of balancing the aesthetics and functionality of miniaturized on-board chargers. As the interior design of vehicles tends to be simple and integrated, on-board chargers must be compact to fit into the vehicle environment, but this often limits the convenience of pulling out by hand. The introduction of this rebound component 2 overcomes the difficulty of pulling out through the internal structure without increasing the external size, maintaining the miniature appearance of the product without sacrificing practicality, thus ensuring the dual optimization of the product in terms of aesthetics and functionality, and ultimately achieving a more comfortable and convenient on-board charging experience for users.

[0029] In one embodiment of the present invention, Figure 3 As shown, the slider 6 includes a block body, a first support column 10 and a guide groove 11; the guide groove 11 is opened on the side of the block body, and one end of the first support column 10 is fixedly connected to the bottom of the block body.

[0030] It should be noted that the top of the block body is fixedly connected to the bottom of the connecting rod 7, so that when the block body slides down, the connecting rod 7 can be brought down with it, so as to achieve the effect of hiding the connecting rod 7 in the support tube 3. One end of the first support column 10 is fixedly connected to the bottom of the block body. The first support column 10 is used to connect the rebound spring to ensure that during the sliding movement of the block body, pressure can be effectively applied to the rebound spring to achieve energy compression storage. The guide groove 11 opened on the block body can guide the upper end sliding trajectory of the positioning plate 5, so that when the upper end of the positioning plate 5 enters the middle and upper groove of the guide groove 11, the connecting rod 7 can be hidden in the support tube 3. When the lower end of the positioning plate 5 enters the middle and lower groove of the guide groove 11, the block body can be released to rise under the thrust of the rebound spring, so as to achieve the effect of protruding the connecting rod 7, so as to facilitate the removal of the vehicle charger through the finger ring 8 on the connecting rod 7.

[0031] The guide groove 11 structure opened on the block body can ensure the sliding track of the upper end of the positioning plate 5, and promote its smooth transition to the upper area of ​​the guide groove 11, so that the connecting rod 7 enters the support tube 3. Conversely, when the upper end of the positioning plate 5 migrates to the lower area of ​​the guide groove 11, the rebound spring uses the elastic force to push the block body upward to move it upward. This process is simultaneously accompanied by more parts of the connecting rod 7 revealing the outer shell 1. The finger ring 8 configured on the top is designed for users to hold it easily, so that the car charger can be easily unplugged.

[0032] In an embodiment of the present invention, a connecting hole is formed at one end of the connecting rod 7 .

[0033] It should be noted that a connecting hole is provided at one end of the connecting rod 7, which is used to connect with the finger ring 8 and facilitate the flipping of the finger ring 8, so that the height of the finger ring 8 can be lowered after flipping when not in use. The material of the finger ring 8 is metal, and it can also be made of cloth or plastic.

[0034] A connecting hole is specially provided at one end of the connecting rod 7 so as to form a stable connection with the finger ring 8, thereby ensuring stability and durability during operation; more importantly, the connecting hole also promotes the flexible flipping of the finger ring 8, so that the finger ring 8 can be folded and folded when not in use, effectively reducing the overall vertical space occupancy, conforming to the demand for efficient use of space in a vehicle environment; the material of the finger ring 8 can be metal, which ensures reliability in long-term use with its tough and durable properties. At the same time, alternative materials such as cloth or plastic can also be selected to meet the diverse preferences of different users for touch and aesthetics.

[0035] The flip design of Ring 8 further solves the storage problem, reduces the visual interference and physical occupancy of the interior space of the cab, and takes into account the flexibility and diversity of material selection, further broadening the product's scope of application and personalized customization potential, thereby enhancing the user experience.

[0036] In one embodiment of the present invention, the finger ring 8 is rotatably connected to the connecting hole.

[0037] It should be noted that the finger ring 8 is tightly combined with the connecting hole via a rotating connection mechanism, thereby giving the finger ring 8 the ability to rotate freely; in this way, not only the flexibility and comfort of the finger ring 8 during operation are enhanced, but also by allowing the finger ring 8 to rotate to a lateral position when not in use, the space occupancy is minimized, greatly improving the compactness of the device and the cleanliness of the vehicle interior environment; the rotating connection method ensures the firm fixation of the finger ring 8, while making it easy for users to easily adjust the posture of the finger ring 8 according to actual needs, without hindering the smoothness of the plug-in and unplug operations, thereby enhancing the product's ease of use and humanized design.

[0038] In one embodiment of the utility model, the support tube 3 includes a tube body, a second support column, a positioning baffle and a rebound spring; the two positioning baffles are respectively arranged on both sides of the opening of the tube body, one end of the second support column is arranged at the bottom of the tube body, and the two ends of the rebound spring are respectively mounted on one end of the first support column 10 and the second support column.

[0039] It should be noted that the cylinder body structure is specially designed to provide a stable linear sliding support platform for the slider 6, ensuring the smoothness and accuracy of the sliding process; one end of the rebound spring is sleeved on the second support column, which enhances the stability of the rebound spring when it is compressed or releases the elastic force, effectively avoiding unnecessary displacement of the rebound spring under the action of downward pressure, and ensuring the stable operation of the spring energy storage and release mechanism. On this basis, two positioning baffles are arranged on both sides of the opening of the cylinder body to form a precise limit for the slider 6, fundamentally preventing the slider 6 from accidentally falling out during the sliding process, and significantly enhancing the safety and durability of the device;

[0040] As a core component, the rebound spring not only absorbs and stores the energy during the downward pressure, but also responds instantly when the external pressure is released, releasing the accumulated elastic potential energy and pushing the slider 6 to slide up to its original position. This not only ensures instant feedback and continuity of operation, but also improves the user's convenience when plugging and unplugging the car charger.

[0041] Ultimately, through the stable support of the cylinder body, the precise positioning of the second support column, the double insurance of the positioning baffle and the efficient design of the rebound spring, we have built an efficient, stable, easy-to-operate, safe and reliable internal mechanical working system for the on-board charger, thereby improving the overall performance and user experience of the product.

[0042] In one embodiment of the present invention, Figure 4As shown, the positioning plate 5 includes a connecting plate 12, a first connecting column 13, a second connecting column 14 and a bearing 15; the two ends of the connecting plate 12 are fixedly connected to one end of the first connecting column 13 and the second connecting column 14 respectively, and the bearing 15 is sleeved on the other end of the first connecting column 13, and the bearing 15 is slidably set in the guide groove.

[0043] It should be noted that the two ends of the connecting plate 12 are closely connected to the first connecting column 13 and the second connecting column 14 through fixed connection, wherein the second connecting column 14 realizes a flexible rotation connection with the side of the cylinder body, thus giving the upper part of the connecting plate 12 a stable rotation fulcrum during the displacement process, ensuring the stability and durability of dynamic operation. In addition, the bearing 15 is sleeved on the first connecting column 13, thereby improving the sliding performance inside the guide groove 11, reducing friction resistance, and improving the smoothness and efficiency of the displacement process;

[0044] Thereby, the dynamic stability and operational smoothness of the internal structure of the vehicle charger are enhanced. Through the cooperation between the connecting plate 12 and the connecting column and the application of the bearing 15, the dual optimization of the rotating connection of the cylinder body and the bearing 15 effectively solves the problems of jamming and wear that may be encountered, providing users with a smoother and lower-noise use experience.

[0045] In one embodiment of the utility model, the mainboard includes a USB socket, a circuit board, a positive electrode ejector pin and a negative electrode spring; the circuit board is arranged in the shell 1, and the two ends of the circuit board are respectively fixedly connected to the USB socket and the positive electrode ejector pin, and the other end of the positive electrode ejector pin passes through one end of the shell 1, and the negative electrode spring is fixedly connected to the circuit board, and the two ends of the negative electrode spring respectively pass through the two sides of the shell 1.

[0046] It should be noted that the circuit board can automatically adjust the output current according to the needs of the connected device. In order to prevent overcurrent from damaging the device or the on-board charger itself, the circuit board is embedded with current limiting and overload protection circuits. When the current is detected to be abnormally high, the protection mechanism will quickly start to reduce or cut off the current output to ensure safety. During the driving of the vehicle, the battery voltage may fluctuate. The voltage stabilization circuit in the circuit board will maintain the stability of the output voltage. Even when the voltage fluctuates, it can ensure that a constant current is provided to the charging device to avoid damage to the device caused by unstable voltage. When the current output is high, the circuit board will also monitor the temperature during the charging process, and use control strategies to dissipate heat or reduce current to prevent overheating, which helps to extend the service life of the on-board charger and charging equipment.

[0047] The positive electrode ejector pin and the negative electrode spring piece are conveniently connected to the inside of the cigarette lighter so that the electric energy of the car can be transmitted to the circuit board. The positive electrode ejector pin and the negative electrode spring piece are respectively made of copper.

[0048] The positive pin and negative spring are designed to seamlessly connect with the internal structure of the car cigarette lighter, ensuring efficient and stable transmission of vehicle power to the circuit board, laying a solid foundation for the power supply of the on-board charger; copper is specially selected as the raw material for the positive pin and negative spring, making full use of the excellent electrical conductivity and good elastic properties of copper, which not only significantly enhances the reliability and durability of electrical contact, but also optimizes the smoothness of current flow, effectively reduces resistance loss and heat generation, thereby ensuring the efficiency and safety of the charging process;

[0049] Ultimately, the core conduction mechanism of the on-board charger is enhanced, ensuring the stability and durability of the connection with the car's cigarette lighter.

[0050] It should be noted that the above-described implementation methods of the utility model do not constitute a limitation on the protection scope of the utility model. Any modification, equivalent replacement and improvement made within the spirit and principle of the utility model shall be included in the protection scope of the claims of the utility model.
