DETAILED DESCRIPTION

[0026] The embodiments of the present application will be further described in conjunction with the drawings and examples. The detailed description of the following examples and drawings are used to exemplarily illustrate the principles of the present application, but cannot be used to limit the scope of the present application, that is, the present application is not limited to the described examples.

[0027] In order to better understand the present application, the present application will be further described in conjunction with the drawings and embodiments:

[0028] Referring to Figure 1 As shown in the figure, the vehicle-mounted charger provided by the embodiment of the present application can realize 180° rotation, which comprises a shell 1 and a charging head 2. The charging head 2 and the shell 1 are rotationally connected, so that the charging head 2 can rotate around the shell 1. The user can adjust the angle of the charging head 2 according to his own needs, so as to adapt to different use scenarios and vehicle internal structures.

[0029] Referring to Figures 2-3 As shown in the figure, the shell 1 of the present embodiment is provided with a spherical part 11 at one end. The charging head 2 is provided with a containing groove for accommodating the spherical part 11. The spherical part 11 is embedded in the containing groove, so that the charging head 2 can rotate in any direction around the spherical part 11. In this way, the charging head 2 of the vehicle-mounted charger can rotate in any direction around the spherical part 11 of the shell 1, so that the charging head 2 is directed to the side that needs to be used, thereby avoiding obstacles around (such as seats, central armrests, etc.), avoiding physical interference with other equipment or internal structures of the vehicle. Not only can the direction of the charging head 2 be adjusted according to the actual situation, thereby facilitating charging operation, but also can adapt to the layout of cigarette lighter sockets of different vehicle models.

[0030] Specifically, since the charging head 2 can rotate in any direction around the spherical part 11, the charging head 2 can be adjusted in multiple directions to realize a 180° rotation function in the circumferential direction, not just front-back swinging or left-right swinging, so that the user can flexibly adjust the direction of the charging head 2 according to the actual situation, so that it is directed to the side that is most convenient to use, and secondly, the environment in the car is usually relatively compact, and there may be seats, central armrests, cup holders and other obstacles around the cigarette lighter socket. Through the design of multi-directional rotation, the charging head 2 can avoid these obstacles and avoid physical interference to ensure that the car charger does not affect the use of other equipment or hinder the normal use of the space in the car.

[0031] It is worth mentioning that the layout and use habits of different users in the car are different, and the car charger provided in the embodiments of the utility model allows users to make personalized adjustments according to their own needs to provide a more comfortable charging experience. For example, the user can adjust the charging head 2 to a position that is not easy to reach to avoid accidentally touching the car charger during driving, or adjust the charging head 2 to a position that is easier to reach to facilitate charging.

[0032] Referring to Figures 3-6 As shown in the figure, the charging head 2 includes a shell body 21, a connecting member 22 and an end cover 23, the connecting member 22 is embedded in the shell body 21, and the end cover 23 and the shell body 21 are connected in a detachable connection manner. Specifically, the detachable connection manner includes but is not limited to threaded connection and buckle connection. In this way, during the production process, when a certain part is damaged, the tester can open the end cover 23 for internal inspection or replacement of parts without the need to replace the entire charging head 2.

[0033] In this embodiment, the shell body 21 has a plug-in end 211 and an open end 212, the connecting member 22 is embedded in the plug-in end 211, the open end 212 is provided with an open port 2121, and the end cover 23 covers the open port 2121 and is detachably connected with the shell body 21. The connecting member 22 and the shell body 21 cooperate to define a containing groove. In this way, not only is the tight connection between the charging head 2 and the shell 1 ensured, but also the structural stability of the entire charging head 2 is enhanced, and moreover, the connecting member 22, as an independent part, can be made of wear-resistant material, thereby prolonging the service life of the car charger.

[0034] Referring to Figure 4As shown, an annular groove is provided on the inner wall of the plug end 211, and a shock-absorbing rubber ring 3 is embedded in the annular groove. The end face of the connecting member 22 abuts against the shock-absorbing rubber ring 3. With this design, the shock-absorbing rubber ring 3 can absorb some vibration, which can reduce noise caused by unstable connection or vibration. Secondly, the contact between the shock-absorbing rubber ring 3 and the outer shell 1 will generate a certain friction force. This friction force can keep the charging head 2 in the position after it is rotated to a certain angle, and will not easily change the tilt angle due to slight external forces (such as bumps in the vehicle). This ensures that the charging head 2 will not shake at will, and thus maintains a stable charging state.

[0035] It is worth mentioning that when the user rotates the charging head 2, the elasticity of the shock-absorbing rubber ring 3 will provide a certain feedback force, making the rotation process smooth and easy to control, thereby improving the rotation feel of the charging head 2.

[0036] See Figure 4 As shown, a limiting groove 111 is provided on the outer wall of the spherical part 11, and at least a portion of the inner wall of the connecting member 22 extends outward to form a protrusion 221, at least a portion of which is located within the limiting groove 111. When the charging head 2 rotates around the spherical part 11 of the outer shell 1 in a certain direction, the protrusion 221 moves accordingly within the limiting groove 111. When the protrusion 221 contacts the side wall of the limiting groove 111, the charging head 2 cannot rotate further, thereby limiting the rotation range of the charging head 2 and preventing the wires inside the charging head 2 from becoming loose or being squeezed and damaged due to excessive rotation.

[0037] See Figure 6 As shown, the charging head 2 contains a circuit board 4, which has a USB port 41 and a Type-C port 42. The charging head 2 also contains a cable reel 24 and a charging cable 25 extending from the reel 24. The charging cable 25 is connected to the circuit board 4. Specifically, the combination of the USB port 41 and the Type-C port 42 can meet the charging needs of different devices. Modern electronic devices such as smartphones, tablets, and laptops widely use these two interface standards. By providing two types of ports, multiple devices can be charged simultaneously on the car charger, eliminating the need to carry multiple chargers.

[0038] See Figures 6-8As shown, the free end of the charging wire 25 is provided with a charging plug 26, the side wall of the charging head 2 is provided with a socket 27 matched with the charging wire 25 and the charging plug 26, a limiting table 271 is arranged in the socket 27, when the charging wire 25 is in the storage state, the charging wire 25 is stored in the charging head 2, at least a part of the charging plug 26 is inserted into the socket 27 and abuts against the limiting table 271; the side wall of the shell body 21 is provided with a first through hole 213 and a second through hole 214, the first through hole 213 corresponds to the Type-C socket 42, and the second through hole 214 corresponds to the USB socket 41.

[0039] Referring to Figure 5 As shown, the end of the shell 1 away from the charging head 2 is provided with a positive cover 5 and a positive contact 6 for cooperating with the automobile lighter socket to realize power input, the shell 1 and the positive cover 5 are threadedly engaged, and the positive contact 6 is exposed outward through the positive cover 5.

[0040] Specifically, the vehicle-mounted charger provided by the embodiment of the utility model further includes a negative spring piece 7, the negative spring piece 7 includes a spring piece main body 71 and a negative contact 72, the spring piece main body 71 and the negative contact 72 are an integral structure, the spring piece main body 71 is located in the shell 1, the side wall of the shell 1 is provided with a mounting hole, and the negative contact 72 protrudes outward from the mounting hole to contact the lighter.
