Description

Technical Field

[0001] This application relates to vehicle chargers, and more particularly to cigarette lighter connection devices. Background Technology

[0002] Currently, many cars only come with a cigarette lighter socket and lack USB charging capabilities. This forces many car owners to draw power from the car's electrical system using the onboard charger and then power their phones and other devices via the charger's USB port. However, many cars have limited storage space and lack a dedicated place to store phones. Typically, a phone holder needs to be installed inside the car to secure the phone, and then a charging cable needs to be connected to the cigarette lighter socket. This charging method requires a car charger, charging cable, and phone holder, which is inconvenient. Summary of the Invention

[0003] The purpose of this application is to provide a practical and convenient cigarette lighter connection device.

[0004] In the first aspect, the cigarette lighter connection device provided in this application adopts the following technical solution: it includes a housing and an elastic metal sheet for connecting the negative electrode of the cigarette lighter and a conductive sheet for connecting the positive electrode of the cigarette lighter, both disposed on the housing. The housing includes an upper housing and a lower housing. Multiple elastic metal sheets are provided. The elastic metal sheets are arc-shaped. The upper and lower ends of the elastic metal sheets are fixed to the upper housing and the lower housing, respectively. The elastic metal sheets protrude radially from the housing. Multiple elastic metal sheets are arranged circumferentially to form a spherical cage. The diameter of the spherical cage is larger than the diameter of the housing. A movable sphere is provided inside the spherical cage. The diameter of the movable sphere is the same as the diameter of the spherical cage. A gap is provided between the movable sphere and the part of the elastic metal sheet protruding from the housing. A carrier is fixed to the movable sphere. The carrier is connected to the conductive sheet and the elastic metal sheet through a conductive structure. A wireless charging module and a mobile phone fixing structure are provided inside the carrier. A power output interface is provided on the side of the carrier.

[0005] By adopting the above technical solution, after the cigarette lighter connector is inserted into the cigarette lighter, the elastic metal sheet undergoes elastic deformation, allowing it to make tight contact with the inside of the cigarette lighter, thus ensuring a tight connection between the connector and the lighter. The cigarette lighter is connected to the carrier via a conductive structure. The carrier powers the mobile phone via a wireless charging module and secures the phone via a phone fixing structure. Because the ball cage formed by the elastic metal sheet firmly engages with the cigarette lighter after the connector is inserted, and simultaneously clamps the movable ball, the carrier's angle is fixed after adjustment. Therefore, in use, the cigarette lighter connector can be directly fixed to the carrier via the phone fixing structure after insertion into the car cigarette lighter, and the phone can be charged via the wireless charging module. This eliminates the need for a phone holder or charging cable in the car, making it convenient to use. A power output interface is also provided in the carrier, enabling multiple power supply methods.

[0006] This application is further configured such that: each end of the elastic metal sheet is provided with an insertion part, the upper shell and the lower shell are annular in shape, and annular slots are provided on the opposite surfaces of the upper shell and the lower shell, and the insertion parts at both ends of the elastic metal sheet are respectively inserted into the slots of the upper shell and the lower shell.

[0007] By adopting the above technical solution, the elastic metal sheet is fixed to the upper and lower shells through plug-in connection, which makes it convenient to insert the movable ball during assembly.

[0008] This application further specifies that: the movable sphere is provided with a cylindrical surface with a diameter smaller than the movable sphere, and in the initial state, the central axis corresponding to the cylindrical surface is consistent with the arrangement direction of the upper shell and the lower shell; there is a gap between the cylindrical surface and the inner wall of the sphere cage for the elastic metal sheet to deform.

[0009] By adopting the above technical solution, a cylindrical surface is designed on the movable sphere, so that an annular gap can be formed between the movable sphere and the ball cage. This allows the ball cage to be evenly stressed when it comes into contact with the inner wall of the cigarette lighter, thus achieving a better connection with the cigarette lighter.

[0010] This application further specifies that: the movable sphere is provided with a mounting hole at the position corresponding to the upper shell, and the mounting hole is provided with a thread; the carrier is provided with a connecting rod, which passes through the upper shell and is connected to the mounting hole by a thread.

[0011] By adopting the above technical solution, the carrier is connected to the movable ball through threads, which reduces the assembly difficulty, that is, the carrier is installed after the movable ball is installed; in addition, there are more diverse options for carrier selection, making the product form more flexible.

[0012] This application further specifies that: the conductive structure includes a conductive spring sheet disposed within the movable sphere, the spring sheet including a protrusion and an elastic part fixed to the inside of the sphere, a through hole provided on the cylindrical surface, the protrusion passing through the through hole and contacting the inner wall of the sphere cage.

[0013] By adopting the above technical solution, the conductive spring contacts the inner wall of the ball cage. During the rotation of the moving ball, the protrusion of the spring can always maintain contact with the inner wall of the ball cage to ensure that both are energized. The elasticity provided by the elastic part further increases the tightness of the connection between the cigarette lighter connection device and the cigarette lighter, making the connection between the two more reliable.

[0014] This application further specifies that the conductive structure includes a conductive rod that can be telescopically disposed in the movable sphere, one end of the conductive rod passing through the movable sphere at a position corresponding to the lower shell, and a spring is disposed in the movable sphere to push the conductive rod to one side of the lower shell; the conductive sheet can move along the axial direction of the lower shell, and the end of the conductive rod that passes through the movable sphere abuts against the conductive sheet.

[0015] By adopting the above technical solution, the spring and connecting rod inside the movable ball provide elastic force for the conductive sheet to return to its original position. The cigarette lighter connector can be inserted deeper into the cigarette lighter. Under the action of the spring and the conductive rod, even if the cigarette lighter connector undergoes a slight outward displacement, the conductive sheet can still maintain contact with the positive electrode of the cigarette lighter. At the same time, when the movable ball swings, the position of the conductive rod on the conductive sheet will shift. Through the action of the spring, the conductive rod can always maintain contact with the conductive sheet, achieving a good conductivity effect.

[0016] This application further specifies that: the conductive structure also includes a conductive contact and a conductive ring disposed at the end of the connecting rod, the conductive ring being coaxially disposed with the connecting rod, the conductive contact being located in the inner ring of the conductive ring, and both the conductive ring and the conductive contact being connected to pins, the pins passing through the connecting rod and electrically connected to the PCB board inside the carrier; a negative conductive part and a positive conductive part are disposed at the bottom of the mounting hole, the negative conductive part being electrically connected to the spring contact, and the positive conductive part being conductive to the conductive rod; the positions of the positive conductive part and the conductive contact are matched, and the positions of the negative conductive part and the conductive ring are matched, and when the connecting rod is rotated to the bottom through the thread, the conductive ring is conductive to the negative conductive part, and the conductive contact is conductive to the positive conductive part.

[0017] By adopting the above technical solution, after the carrier is screwed into the mounting hole through the connecting rod, the conductive ring at the end of the connecting rod can be connected to the negative conductive part, and the conductive contact at the end of the connecting rod can be connected to the positive conductive part. As long as the connecting rod is screwed to the bottom of the mounting hole, the positive and negative electrodes can be connected, and the PCB board can be powered on.

[0018] This application further specifies that: a limiting part is provided at the end of the conductive rod, one end of the spring abuts against the limiting part, and the other end of the spring abuts against the positive conductive part.

[0019] By adopting the above technical solution, the positive conductive part and the conductive rod are connected by a spring, and at the same time, both the positive and negative conductive parts can move along the axis of the movable ball. Under the action of the spring, the positive conductive part can make better contact with the conductive contact and maintain good conductivity.

[0020] This application further specifies that the mobile phone fixing structure is a magnetic module disposed on the carrier.

[0021] By adopting the above technical solution and using a magnetic module to attach and fix the mobile phone, the shape and structure of the carrier can be made simpler and more compact, and the cigarette lighter connection device can be adapted to more vehicle environments.

[0022] Compared with the prior art, this application has the following advantages: after the mobile phone is fixed on the carrier, it can stably support and fix the mobile phone. The carrier attracts the mobile phone through the magnetic module and wirelessly charges the mobile phone through the wireless charging module. At the same time, the power output module on the carrier can supply power to other devices through the charging cable, making it more convenient to use and more diversified in power supply scenarios.

[0023] The cigarette lighter connection device has a compact overall structure. The elastic metal sheet can not only conduct current, but also hold the movable ball tightly, making the angle of the carrier adjustable. After the carrier angle is adjusted, it can also limit the further swing of the carrier. Attached Figure Description

[0028] The following is in conjunction with the appendix Figure 1 -Appendix Figure 3 This application will be described in further detail below.

[0029] A cigarette lighter connection device, as shown in the reference Figure 1 , Figure 2 The device includes an upper housing 1 and a lower housing 2, which are joined together to form the outer shell of the cigarette lighter connection device. Multiple elastic metal sheets 31 are disposed between the upper housing 1 and the lower housing 2, forming a spherical cage 3. Each end of the elastic metal sheet 31 has a plug-in portion 311. The upper housing 1 and the lower housing 2 are annular in shape. Each of the opposing surfaces of the upper housing 1 and the lower housing 2 has a spherical surface 12 and annularly arranged slots 11. The spherical surface 12 matches the outer contour of the elastic metal sheet 31. The slots 11 are used to engage with the plug-in portions 311 of the elastic metal sheet 31. When the plug-in portions 311 at both ends of the elastic metal sheet 31 are inserted into the slots 11 of the upper housing 1 and the lower housing 2, the elastic metal sheet 31 can be fixed to the upper housing 1 and the lower housing 2. The outer diameter of the ball cage 3 formed by the elastic metal sheet 31 is larger than the inner diameter of the cigarette lighter. After the elastic metal sheet 31 is fixed with the upper housing 1 and the lower housing 2, the elastic metal sheet 31 has a radially protruding part relative to the upper housing 1 and the lower housing 2. After the cigarette lighter connecting device is inserted into the cigarette lighter, it is deformed by the elastic metal sheet 31 pressing against the inner wall (negative electrode) of the cigarette lighter, so that the cigarette lighter connecting device can be better inserted into the cigarette lighter.

[0030] Reference Figure 2 , Figure 3 The ball cage 3 contains a movable sphere 4, the outer diameter of which is the same as the inner diameter of the ball cage 3. The ball cage 3 achieves its overall shape through the spherical surfaces 12 on the upper shell 1 and lower shell 2, allowing the ball cage 3 to effectively confine the movable sphere 4 within it, enabling the movable sphere 4 to swing 360° within the ball cage 3. The movable sphere 4 has a cylindrical surface 49 with a diameter smaller than that of the movable sphere 4. In its initial state (e.g.) Figure 2In the state shown, the central axis corresponding to the cylindrical surface 49 is aligned with the arrangement direction of the upper shell 1 and the lower shell 2, so that when the cigarette lighter connecting device is inserted into the cigarette lighter, there is an annular gap between the cylindrical surface 49 and the inner wall of the ball cage 3 for the elastic metal sheet 31 to deform. The movable ball 4 is provided with a conductive spring sheet 41. This embodiment describes one of the spring sheets 41. The spring sheet 41 includes a U-shaped or V-shaped protrusion 411 and an elastic part 412 fixed inside the movable ball 4. The cylindrical surface 49 is provided with a through hole 42. The protrusion 411 passes through the through hole 42 and abuts against the inner wall of the ball cage 3 to achieve conductivity. The elastic part 412 can apply an elastic force to the protrusion 411 toward the inner wall of the ball cage 3, so that the protrusion 411 and the inner wall of the ball cage 3 maintain good contact, and achieve conductivity between the spring sheet 41 and the negative electrode of the cigarette lighter. The movable ball 4 can be provided with multiple spring sheets 41. The more spring sheets there are, the better the conductivity.

[0031] Reference Figure 2 , Figure 3 The movable sphere 4 has a coaxially arranged and through telescopic hole 43 and a mounting hole 48 at its center. The central axis of the telescopic hole 43 is coaxial with the central axis of the cylindrical surface 49. One end of the telescopic hole 43 passes through the side of the lower shell 2 corresponding to the movable sphere 4. A retractable conductive rod 44 is provided inside the telescopic hole 43. One end of the conductive rod 44 extends through the telescopic hole 43 and out of the movable ball 4. The other end of the conductive rod 44 is provided with a limiting part 441. The diameter of the limiting part 441 is larger than that of the rod body, which is used to limit the maximum length of the conductive rod 44 that extends out of the movable ball 4. A spring 45 is provided inside the telescopic hole 43 to push the conductive rod 44 into the lower housing 2. The lower housing 2 is provided with a conductive plate 21 that can move along the axis of the lower housing 2. The surface of the conductive plate 21 corresponding to the conductive rod 44 can be spherical. When the movable ball 4 deflects, under the action of the spring 45, the extension and retraction of the conductive rod 44 ensures that the conductive rod 44 can always maintain contact with the conductive plate 21 to ensure good conductivity. In this embodiment, the surface of the conductive plate 21 facing away from the conductive rod 44 is also set as spherical to facilitate better contact with the positive electrode of the cigarette lighter and realize the conduction of current.

[0032] Reference Figure 2 , Figure 3The mounting hole 48 is threaded and used to fix the carrier 5. In this embodiment, the carrier 5 is provided with a connecting rod 51, the end of which is threaded. The carrier 5 is fixed to the mounting hole 48 by the connecting rod 51 through the thread. A conductive contact 511 and a conductive ring 512 are respectively provided at the end of the connecting rod 51. The conductive ring 512 is coaxially arranged with the connecting rod 51. The conductive contact 511 is located at the center of the end of the connecting rod 51, that is, the conductive contact 511 is located in the inner ring of the conductive ring 512. The inner diameter of the conductive ring 512 is larger than that of the conductive contact 511, so that the conductive contact 511 and the conductive ring 512 do not contact each other. Both the conductive ring 512 and the conductive contact 511 are connected to pins 513. The pins 513 pass through the connecting rod 51 and connect to the PCB board 52 inside the carrier 5. The bottom of the mounting hole 48 is provided with a negative conductive part 47 and a positive conductive part 46. The negative conductive part 47 is electrically connected to the spring contact 41 via a wire 413, realizing the conduction between the negative conductive part 47 and the spring contact 41. The positive conductive part 46 is connected to the conductive rod 44 by a spring 45. The positive conductive part 46 is located at the center of the bottom of the mounting hole 48, so that the position of the positive conductive part 46 matches the position of the conductive contact 511, and the positive conductive part 46 can slide along the central axis of the mounting hole 48. The elastic force of the spring 45 makes the positive conductive part 46 protrude from the bottom of the mounting hole 48. When there is no external force, the top of the positive conductive part 46 is higher than the negative conductive part 47. The position of the negative conductive part 47 matches the conductive ring 512. The negative conductive part 47 can be a point or a ring. When the connecting rod 51 is rotated to the bottom through the thread, the conductive ring 512 contacts and conducts with the negative conductive part 47, and the conductive contact 511 contacts and conducts with the positive conductive part 46, thus finally realizing the connection between the PCB board 52 in the carrier 5 and the cigarette lighter.

[0033] Reference Figure 2 , Figure 3 The PCB board 52 of the carrier 5 is provided with a power output interface 55, which converts the 12V voltage from the cigarette lighter into a suitable voltage for output. In this application, the power output interface 55 is USB-C, and the specific number can be set on the PCB board 52 according to requirements. A structure for clamping a mobile phone can be installed on the carrier 5, so that the mobile phone can be directly fixed on the carrier 5. Since the movable ball 4 fixing the carrier 5 can rotate relative to the ball cage 3, the angle of the clamped mobile phone can be adjusted. As a preferred embodiment of this application, a magnetic module 53 and a wireless charging module 54 are provided in the carrier 5, for example, using the same structure as the MagSafe charger, to realize wireless charging of specific mobile phone models or mobile phones with magnetic modules 53.

[0034] The implementation principle of this embodiment is as follows: After the cigarette lighter connecting device is inserted into the cigarette lighter, since the diameter of the ball cage 3 formed by the elastic metal sheet 31 is larger than the diameter of the cigarette lighter, the elastic metal sheet 31 undergoes elastic deformation after being fully inserted into the cigarette lighter, so that the elastic metal sheet 31 makes tight contact with the inner wall of the cigarette lighter, and the cigarette lighter connecting device is tightly connected to the cigarette lighter. The negative terminal of the cigarette lighter sequentially conducts through the elastic metal sheet 31, the spring sheet 41, the wire 413, the negative conductive part 47, and the conductive ring 512, and finally conducts through the PCB board 52 in the carrier 5; the conductive sheet 21 of the lower shell 2 contacts the positive terminal at the bottom of the cigarette lighter, and the positive terminal of the cigarette lighter sequentially conducts through the conductive sheet 21, the conductive rod 44, the positive conductive sheet 21, and the conductive contact 511, and finally conducts through the PCB board 52 in the carrier 5, so as to realize the power supply to the PCB board 52. The PCB board 52 can realize the power supply to the power output interface 55 and the wireless charging module 54.

[0035] Because the ball cage 3 formed by the elastic metal sheet 31 allows the movable ball 4 to move relative to each other within the ball cage 3, the deformation of the elastic metal sheet 31 after the cigarette lighter connection device is inserted into the cigarette lighter allows the ball cage 3 to provide a stronger clamping force to the movable ball 4, enabling the movable ball 4 to obtain a stronger frictional force. Thus, after the mobile phone is fixed on the carrier 5, it can stably support the mobile phone. The carrier 5 uses the magnetic module 53 to attract the mobile phone and uses the wireless charging module 54 to wirelessly charge the mobile phone. At the same time, the power output module on the carrier 5 can supply power to other devices through the charging cable.

[0036] The cigarette lighter connection device has a compact overall structure. The elastic metal sheet 31 can not only conduct current, but also hold the movable ball 4 tightly, making the angle of the carrier 5 adjustable. After the angle of the carrier 5 is adjusted, it can limit the swing of the carrier 5.

[0037] The embodiments described in this specific implementation are preferred embodiments of this application and are not intended to limit the scope of protection of this application. Identical components are represented by the same reference numerals. Therefore, all equivalent changes made to the structure, shape, and principle of this application should be covered within the scope of protection of this application.
