Technical Field

[0001] This utility model relates to the field of charging equipment technology, specifically to a novel travel adapter charger. Background Technology

[0002] With the rapid development of the global economy, more and more people are traveling abroad. However, due to historical reasons, safety standards, and market demand, different countries often use different power plug standards. For example, some countries use three-prong plugs, while others use two-prong plugs; and the shape of the prongs also differs, such as flat prongs, round prongs, or round-flat prongs, which brings inconvenience to travelers. In response, some charger manufacturers have launched travel adapters that are compatible with different power socket standards.

[0003] Existing travel adapters integrate various standard charging plugs into a single charging plug body. Users simply push out the appropriate plug to use the device. While this design allows travelers to use the device in countries with different power outlet standards, its complex internal structure and high precision requirements during assembly result in high production costs. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a new type of travel adapter charger, so as to solve the problem that the existing new travel adapter chargers have a relatively complex internal structure due to the inclusion of charging plugs of different standard models, and the high production cost caused by the high positioning and installation accuracy requirements of each charging plug during the assembly process.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] This application provides a novel travel adapter charger, including a charger body and a charging plug. A connecting groove is formed at the top edge of one side of the charger body, and a connecting block is formed at one side of the charging plug. The connecting block is used to vertically insert into the connecting groove from the top edge of the charger body. A locking device is also provided between the charger body and the charging plug, which controls the vertical withdrawal of the connecting block from the connecting groove. A moving contact and a stationary contact are electrically connected between the charger body and the charging plug. The locking device includes a locking hole and a locking block. The locking hole is a horizontal opening structure located on one side of the connection groove on the charger body. The locking hole is located adjacent to the center of the top of the connection groove. The locking block includes a push-pull part, and the bottom end of the push-pull part is provided with a locking part. The locking part can be horizontally inserted into the locking hole. The locking part is used to restrict the charging plug from sliding out of the charger body in the vertical direction. The top of the charger body is formed with a sliding groove. The push-pull part is slidably installed in the sliding groove. The push-pull part is used to drive the locking part to slide into or out of the locking hole.

[0007] Furthermore, guide grooves are formed on both outer sides of the connecting groove, and guide blocks are formed on both outer sides of the connecting block. A pair of guide blocks are used to be vertically inserted into the guide grooves from the top of the charger body.

[0008] Furthermore, the moving contacts are in pairs, and the pair of moving contacts are respectively disposed at the bottom end of the guide block. The stationary contacts are in pairs, and the pair of stationary contacts are respectively fixedly disposed at the bottom end of the guide groove.

[0009] Furthermore, the top of the connecting groove is formed with a guide portion to facilitate the insertion of the connecting block.

[0010] The beneficial effects of this utility model are as follows:

[0011] By adopting the above-mentioned new travel adapter charger, the charger body and the charging plug are assembled separately. The charger body can be assembled with various standard models of charging plugs. When a certain standard model of charging plug is required, the charging plug can be installed on the charger body by inserting the connecting block on the charging plug into the connecting slot on the charger body and locking it with the locking device. This solves the problems of high assembly positioning accuracy and high production cost caused by the existing method of installing various standard models of charging plugs on the charger body.

Detailed Implementation

[0023] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0024] See appendix Figure 1 To be continued Figure 3As shown, this embodiment provides a novel travel adapter charger 10, including a charger body 100 and charging plugs 200. Multiple charging plugs 200 are included, meaning the charger body 100 is equipped with multiple charging plugs 200 of different standard models to accommodate use with different standard charging plugs 200. In this embodiment, the charger body 100 and the charging plugs 200 are installed separately, and the charger body 100 is equipped with multiple charging plugs 200 of different standard models; the number of charging plugs 200 can be flexibly set.

[0025] See attached document Figure 1 To be continued Figure 7 As shown, a connecting groove 101 is formed at the top edge of one side of the charger body 100. Correspondingly, a connecting block 301 is formed on one side of the charging plug 200. The connecting block 301 can be vertically inserted into the connecting groove 101 along the top edge of the charger body 100. After the connecting block 301 is installed in the connecting groove 101, the connecting block 301 can only slide vertically along the connecting groove 101. This design allows for easy removal of the charging plug 200 originally installed on the charger body 100 when it is necessary to replace it with a different standard model, and easy installation of the replaced charging plug 200 on the charger body 100. In some embodiments, refer to the attached figure. Figure 6 As shown, in order to facilitate the better insertion of the connecting block 301 into the connecting groove 101, a guide portion 103 is formed at the top of the connecting groove 101 to facilitate the insertion of the connecting block 301.

[0026] To ensure a tight connection between the charging plug 200 and the charger body 100, a locking device 400 is provided between the charging plug 200 and the charger body 100. The locking device 400 can lock the charging plug 200 and the charger body 100 to prevent them from shaking.

[0027] See attached document Figure 3 and attached Figure 6 As shown, to enhance the stability of the connection between the charger body 100 and the charging plug 200, guide grooves 102 are formed on both outer sides of the connecting groove 101, and guide blocks 302 are formed on both outer sides of the connecting block 301. A pair of guide blocks 302 are used to vertically insert from the top of the charger body 100 into the guide grooves 102. The guide grooves 102 and guide blocks 302 limit the charging plug 200 and the charger body 100 in the lateral direction, making it less likely for the charger body 100 and the charging plug 200 to wobble from side to side.

[0028] See attached document Figure 2 Appendix Figure 6 and attached Figure 7 As shown, in this embodiment, a moving contact 303 and a stationary contact are electrically connected between the charger body 100 and the charging plug 200. After the charging plug 200 is installed on the charger body 100, the charging plug 200 and the charger body 100 are electrically connected through the moving contact 303 and the stationary contact. It can be understood that the moving contact 303 and the stationary contact are used to achieve electrical connection between the contacting parts, and they can adopt commonly used contact structures in electrical appliances, such as the moving contact 303 and stationary contact structure similar to that on a switch knife. The moving contact 303 is located at the middle position of the bottom end of the guide block 302, and is a groove located at the middle position of the bottom end of the guide block 302 (see attached diagram). Figure 7 As shown in the figure, the stationary contact is a conductive metal contact piece (not shown) located at the bottom end of the guide groove 102. The conductive metal contact piece extends vertically upward from the bottom end of the guide groove 102. After the charging plug 200 is inserted and installed in place along the charger body 100, the conductive metal contact piece will be inserted into the clamping groove on the guide block 302. The conductive metal contact piece contacts and is electrically connected with the clamping groove, thereby realizing the electrical connection between the charger body 100 and the charging plug 200.

[0029] See attached document Figure 1 Appendix Figure 2 and appendix Figure 5 To be continued Figure 7 As shown, in this embodiment, the locking device 400 includes a locking hole 403 and a locking block. The locking hole 403 is a horizontal opening structure located on one side of the connecting groove 101 on the charger body 100. In this embodiment, the locking hole 403 is an opening structure with a rectangular cross-section. In some embodiments, the locking hole 403 is located near the center of the top of the connecting groove 101.

[0030] The locking block includes a push-pull portion 401, and a locking portion 402 is provided at the bottom end of the push-pull portion 401. In this embodiment, the locking portion 402 has a rectangular shape, and its external dimensions are the same as the opening size of the locking hole 403. Thus, when the locking portion 402 is horizontally inserted into the locking hole 403, the outer surface of the locking portion 402 contacts the inner wall of the locking hole 403, and the locking portion 402 and the locking hole 403 form interference in the vertical direction.

[0031] The locking part 402 can be horizontally inserted into the locking hole 403. The locking part 402 is used to prevent the charging plug 200 from sliding out of the charger body 100 in the vertical direction. The top of the charger body 100 is formed with a sliding groove 304. The push-pull part 401 is slidably installed in the sliding groove 304. The push-pull part 401 is used to drive the locking part 402 to slide into or out of the locking hole 403. That is, the locking device 400 has two states: a locked state and an unlocked state. When the push-pull part 401 slides horizontally along the slide groove 304 towards the charger body 100 and slides into place, the push-pull part 401 will simultaneously drive the locking part 402 to slide during the horizontal sliding process, so that the locking part 402 is horizontally inserted into the locking hole 403. The outer surface of the locking part 402 contacts the inner wall of the locking hole 403. The locking part 402 and the locking hole 403 form interference in the vertical direction, realizing the fixed locking of the charging plug 200 on the charger body 100. At this time, the locking device 400 is in the locked state. When the push-pull part 401 is pushed in the opposite direction, the locking part 402 moves in the opposite direction with the push part. That is, the locking part 402 is pulled out horizontally from the locking hole 403 and gradually disengages from the locking hole 403. At this time, the locking device 400 is in the unlocked state, and the charging plug 200 can slide upward in the vertical direction and disengage from the charger body 100, so that the charging plug 200 can be replaced.

[0032] See attached document Figure 8 and attached Figure 9 As shown, there are different standard models of charging plugs 200. When it is necessary to replace the charging plug 200 with a different standard model, the user only needs to operate the locking device 400 on the charger body 100 to move the push-pull part 401 to the unlocked position. The user then moves the original charging plug 200 upward and detaches it from the charger body 100, installs the charging plug 200 that needs to be used on the charger body 100, and locks it with the locking device 400.

[0033] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
