[0024] See Figures 1 to 3 An embodiment of the present invention provides a cigarette lighter connection device for electrically connecting to a vehicle-mounted cigarette lighter. The cigarette lighter connection device includes a rubber-coated structure 1, through which a positive electrode structure 2 and a negative electrode structure 3 are led out; wherein the rubber-coated structure 1 forms an assembly space; the positive electrode structure 2 is passed through the rubber-coated structure 1, partially accommodated in the assembly space and partially protruding from the outside of the rubber-coated structure 1, and the positive electrode structure 2 is used to electrically connect to the positive electrode of the vehicle-mounted cigarette lighter; the negative electrode structure 3 is connected to the rubber-coated structure 1 and protrudes from the outside of the rubber-coated structure 1, and the negative electrode structure 3 is used to electrically connect to the negative electrode of the vehicle-mounted cigarette lighter; and the positive electrode structure 2 and the negative electrode structure 3 are arranged at intervals.

[0025] In an embodiment of the present invention, the positive electrode structure 2 is passed through the rubber-coated structure 1, with a portion of the positive electrode structure 2 located within the assembly space of the rubber-coated structure 1 and a portion protruding from the outside of the rubber-coated structure 1. Therefore, the positive electrode structure 2 and the rubber-coated structure 1 can be assembled and connected, and the portion of the positive electrode structure 2 protruding from the outside of the rubber-coated structure 1 can be used to electrically connect to the positive electrode of the vehicle cigarette lighter. The negative electrode structure 3 is connected to the rubber-coated structure 1 and protrudes from the outside of the rubber-coated structure 1. Therefore, the negative electrode structure 3 can be electrically connected to the negative electrode of the vehicle cigarette lighter. In this embodiment of the present invention, the positive electrode structure 2 and the negative electrode structure 3 are led out through the rubber-coated structure 1, so that the cigarette lighter connection device can be used to electrically connect to the vehicle cigarette lighter, and the positive electrode structure 2 and the negative electrode structure 3 can be assembled and connected to the rubber-coated structure 1 and the negative electrode structure 3 can be assembled and connected to the rubber-coated structure 1. Compared with the technical solution in the related art of assembling the positive electrode structure 2 and the negative electrode structure 3 through two shells, the embodiment of the present invention can improve the structural assembly stability and enhance the user experience.

[0026] Further, in some embodiments, the positive electrode structure 2 extends along the axial direction of the encapsulation structure 1, and the positive electrode structure 2 includes an electrically connecting bump 21 protruding outward from the encapsulation structure 1, which is used for electrically connecting with the positive electrode of the vehicle-mounted cigarette lighter; the negative electrode structure 3 includes an electrically connecting ring arranged around the outer circumferential side of the encapsulation structure 1 and protruding outward from the encapsulation structure 1, which is used for electrically connecting with the negative electrode of the vehicle-mounted cigarette lighter.

[0027] Specifically, the encapsulation structure 1 is provided with a through hole passing through in the axial direction, and the positive electrode structure 2 can be arranged in the through hole. The positive electrode structure 2 includes a main body portion and the electrically connecting bump 21 connected with each other, wherein the main body portion is located in the assembly space, and the electrically connecting bump 21 is located outside the assembly space and protrudes outward from the outer surface of the encapsulation structure 1. Therefore, when the cigarette lighter connecting device is connected with the vehicle-mounted cigarette lighter, the electrically connecting bump 21 of the positive electrode structure 2 can be used for directly electrically contacting the positive electrode of the vehicle-mounted cigarette lighter. In addition, a recess is arranged on the outer circumferential side of the encapsulation structure 1, and the electrically connecting ring is located in the recess and partially protrudes outward from the recess. Therefore, when the cigarette lighter connecting device is connected with the vehicle-mounted cigarette lighter, the part of the electrically connecting ring of the negative electrode structure 3 protruding outward from the recess can be used for directly electrically contacting the negative electrode of the vehicle-mounted cigarette lighter.

[0028] Further, in some embodiments, the encapsulation structure 1 includes a first encapsulation layer 11 and a second encapsulation layer 12, and the first encapsulation layer 11 is arranged around the outer circumferential side of the second encapsulation layer 12, and the first encapsulation layer 11 and the second encapsulation layer 12 together define the assembly space.

[0029] Specifically, when the encapsulation process is performed, the encapsulation process can be divided into two times, so as to divide the first encapsulation layer 11 and the second encapsulation layer 12, wherein the first encapsulation layer 11 is wrapped around the outer circumferential side of the second encapsulation layer 12, so as to improve the hardness requirement of the encapsulation structure 1. In addition, the second encapsulation layer 12 defines part of the assembly space, and the height of the first encapsulation layer 11 in the axial direction is higher than the height of the second encapsulation layer 12, so that the first encapsulation layer 11 is wrapped around the outer circumferential side of the second encapsulation layer 12, and the two together form the assembly space, which can be used for connecting the positive electrode structure 2 and the like, so as to improve the structural strength.

[0030] For example, the encapsulation structure 1 can be made of PE (Polyethylene) material.

[0031] Furthermore, in some embodiments, the cigarette lighter connection device also includes an indicator light 4, a first wire and a second wire (not shown in the figure), the indicator light 4 is connected to the rubber-coated structure 1, the positive pole of the indicator light 4 is electrically connected to the positive electrode structure 2 through the first wire, and the first wire is located in the assembly space; the negative pole of the indicator light 4 is electrically connected to the negative electrode structure 3 through the second wire, and the second wire is located in the assembly space; the indicator light 4 is used to emit light to the outside when it is in passage.

[0032] Specifically, the cigarette lighter connection device may further include an indicator light 4, wherein the indicator light 4 is connected to the rubber-encapsulated structure 1, thereby enabling assembly and connection of the indicator light 4. Furthermore, the positive electrode of the indicator light 4 is electrically connected to the positive electrode structure 2 via a first wire, and the negative electrode of the indicator light 4 is electrically connected to the negative electrode structure 3 via a second wire. Therefore, when the cigarette lighter connection device is connected to the vehicle cigarette lighter and the circuit is conductive, the indicator light 4 will illuminate externally, serving as a reminder. The user can determine whether the circuit between the cigarette lighter connection device and the vehicle cigarette lighter is properly connected by whether the indicator light 4 is illuminated. In addition, both the first wire and the second wire are located within the assembly space, which can make the overall appearance more neat and simple, and protect the wires from being exposed and damaged.

[0033] Furthermore, in some embodiments, the indicator light 4 is inserted into the encapsulated structure 1, and the indicator light 4 includes a connecting portion and a light-emitting portion. The light-emitting portion is connected to the connecting portion, and the connecting portion is located in the assembly space. The connecting portion leads to the positive and negative poles of the indicator light 4, and the light-emitting portion is exposed outside the assembly space.

[0034] Specifically, indicator light 4 can be an LED lamp bead, etc., and the main luminous part of indicator light 4 is the light-emitting portion. Therefore, by exposing the light-emitting portion outside the assembly space, the light of indicator light 4 can be illuminated to the outside for the user to see. In addition, the connecting portion is connected within the assembly space, and the positive and negative poles of indicator light 4 are led out of the connecting portion. Therefore, within the assembly space, the positive pole of indicator light 4 can be electrically connected to the positive pole structure 2 via a first wire, and the negative pole of indicator light 4 can be electrically connected to the negative pole structure 3 via a second wire. In addition, indicator light 4 is inserted into the encapsulated structure 1, thereby achieving the assembly connection of the entire indicator light 4.

[0035] Furthermore, in some embodiments, the encapsulated structure 1 is a transparent structure, the assembly space is provided with an assembly position, and the indicator light 4 is assembled at the assembly position.

[0036] Specifically, the encapsulated structure 1 can be made of a transparent material. Therefore, even when the indicator light 4 is mounted in its assembly position within the assembly space, the light emitted by the indicator light 4 can still be transmitted through the transparent encapsulated structure 1 to the outside for viewing by the user. Similarly, within the assembly space, the positive electrode of the indicator light 4 can be electrically connected to the positive electrode structure 2 via a first wire, and the negative electrode of the indicator light 4 can be electrically connected to the negative electrode structure 3 via a second wire.

[0037] For example, the encapsulated structure 1 may be made of transparent PET (Thermoplastic Elastomer) material.

[0038] Furthermore, the indicator light 4 is spaced apart from the positive electrode structure 2 and the negative electrode structure 3; the light emitting direction of the indicator light 4 is toward the peripheral side of the rubber-coated structure 1; or, the light emitting direction of the indicator light 4 is toward one end of the rubber-coated structure 1 along the axial direction.

[0039] Specifically, in some embodiments, whether the light-emitting portion of the indicator light 4 is exposed on the outside of the encapsulated structure 1 or the indicator light 4 is located in the assembly space, the light-emitting direction of the indicator light 4 can be changed by adjusting the setting position of the indicator light 4, so that the light of the indicator light 4 can be clearly viewed by the user.

[0040] In some specific embodiments, the indicator light 4 is arranged on the peripheral side of the rubber-coated structure 1, and the axial direction of the indicator light 4 is parallel to the radial direction of the rubber-coated structure 1. At this time, the light-emitting part of the indicator light 4 is exposed on the outside of the rubber-coated structure 1, and the light-emitting direction of the indicator light 4 is toward the peripheral side of the rubber-coated structure 1. The user can check the light-emitting status of the indicator light 4 on the peripheral side of the rubber-coated structure 1, so as to judge whether the circuit between the cigarette lighter connecting device and the vehicle-mounted cigarette lighter is normally connected.

[0041] In some specific embodiments, the positive electrode structure 2 is arranged at one axial end of the rubber-coated structure 1, the indicator light 4 is arranged at the other axial end of the rubber-coated structure 1 and the light-emitting portion of the indicator light 4 is exposed outside the rubber-coated structure 1, the axial direction of the indicator light 4 is parallel to the axial direction of the rubber-coated structure 1, and the light-emitting direction of the indicator light 4 is toward the end away from the positive electrode structure 2. Therefore, the user can check the light-emitting status of the indicator light 4 from the end of the rubber-coated structure 1 axially away from the positive electrode structure 2, so as to determine whether the circuit between the cigarette lighter connection device and the vehicle-mounted cigarette lighter is normally connected.

[0042] It can be understood that in some specific embodiments, the rubber-coated structure 1 is a transparent structure, and the indicator light 4 is assembled at the assembly position in the assembly space. By changing the structure of the assembly position, it is also possible to make the light-emitting direction of the indicator light 4 toward the peripheral side of the rubber-coated structure 1 or the light-emitting direction of the indicator light 4 toward the end away from the positive electrode structure 2, which will not be elaborated here.

[0043] Furthermore, in some embodiments, the cigarette lighter connection device also includes a connection structure, which is partially arranged in the assembly space and partially located outside the assembly space, the positive pole of the connection structure is electrically connected to the positive pole structure 2, and the negative pole of the connection structure is electrically connected to the negative pole structure 3, and the connection structure is used to electrically connect to the outside.

[0044] Specifically, the positive electrode of the connection structure is electrically connected to the positive electrode structure 2, and the negative electrode of the connection structure is electrically connected to the negative electrode structure 3. Therefore, when the entire cigarette lighter connection device is connected to the vehicle's cigarette lighter, the connection structure can extract power. The connection structure is partially located outside the assembly space, allowing it to be directly used for electrical connection to external mobile electronic devices. In this arrangement, during use, simply connect the cigarette lighter connection device to the vehicle's cigarette lighter, then connect the external mobile electronic device to the connection structure to extract the vehicle's power, thereby enabling charging of various mobile electronic devices.

[0045] Furthermore, in some embodiments, the connection structure has an interface, and the interface includes a USB interface or a Type-C interface. Therefore, the scope of use of the cigarette lighter connection device can be enriched and the practicality can be enhanced.

[0046] Furthermore, in some embodiments, a grip portion is provided on the outer periphery of the rubber-coated structure 1. Specifically, the grip portion can be a groove provided on the outer periphery of the rubber-coated structure 1, thereby increasing friction for the user to hold.

[0047] In the above embodiments, the description of each embodiment has its own focus. For parts that are not described in detail in a certain embodiment, reference can be made to the relevant descriptions of other embodiments.

[0048] The above is a description of the technical solution provided by the present invention. For those skilled in the art, according to the ideas of the embodiments of the present invention, there may be changes in the specific implementation methods and application scope. In summary, the content of this specification should not be understood as limiting the present invention.
