[0031] Referring to Figure 1 , Fig. 1 shows the structure of the charger system plug-in of an embodiment of the present application. The charger system of the embodiment of the present application comprises a charger 1 and a matching piece 2, which can be selectively plugged into the lower end of the charger 1. The matching piece 2 is selectively fixedly connected to the working surface, wall surface or tool box and the like to facilitate the plug-in of the charger 1.
[0032] The charger 1 can have a main body part 11, a connecting assembly 12 arranged on the lower side of the main body part 11, a holding part 14 arranged on the upper side of the main body part 11, and a battery accommodating part 15 arranged on the main body part 11. The holding part 14 is fixedly connected with the main body part 11, and extends along the length direction of the main body part 11; the battery accommodating part 15 is provided in plurality, and arranged on the circumferential side of the main body part 11; preferably, the battery accommodating part 15 allows the battery pack (not shown) to be plugged in perpendicularly to the plug-in direction; the connecting assembly 12 is detachably connected with the matching piece 2.
[0033] Referring to Figure 2 and Figure 3 , Fig. 2 shows a schematic structural view of the charger system in an embodiment of the present application without being plugged in, Figure 3 Fig. 2 shows a schematic structural view of the charger in another view in an embodiment of the present application. The connector 2 is configured with a guide portion 21 on the side facing the charger 1. The guide portion 21 extends from the side of the connector 2 facing the charger 1 to the charger 2. The guide portion 21 extends along the plugging direction of the charger 1. The guide portion 21 is configured with a first guide groove 211 and a first guide strip 212 along the plugging direction of the charger 1. The first guide groove 211 and the first guide strip 212 are each configured with two. One first guide groove 211 and one first guide strip 212 on the same side form a group. The two first guide grooves 211 are respectively configured on two opposite sides of the guide portion 21. The two first guide grooves 211 can be symmetrically configured or staggered up and down. The two first guide grooves 211 can be of the same size or different sizes. The first guide strip 212 of the same group is configured between the first guide groove 211 and the charger 1. The connecting assembly 12 extends with a docking portion 121 on the side facing the connector 2. The docking portion 121 is plugged with the guide portion 21. Specifically, the docking portion 141 is configured with a second guide groove 1212 and a second guide strip 1211. The second guide groove 1212 and the second guide strip 1211 extend along the plugging direction of the charger 1. The second guide strip 1211 is configured with at least two and is respectively plugged with the two first guide grooves 211 to limit the movement of the charger 1 along the plugging direction, so as to improve the plugging stability between the charger 1 and the connector 2.
[0034] In some preferred embodiments, one of the charger 1 and the connector 2 is further configured with a stop portion 1213. The stop portion 1213 limits the charger 1 and the connector 2 from moving continuously after being plugged in along the plugging direction. Preferably, the stop portion 1213 is configured on the charger 1. Specifically, the stop portion 1213 is configured on the docking portion 141 and is adjacent to the second guide groove 1212 in the plugging direction. When being plugged in, the first guide strip 212 abuts against the stop portion 1213 to limit the movement of the first guide strip 212 in the second guide groove 1412, which is conducive to the plugging stability of the charger system and prevents direct decoupling when being plugged in along the plugging direction.
[0035] In some preferred embodiments, the connecting assembly 12 is further provided with a locking block 122, which is selectively coupled with the locking slot 22, and is decoupled from the locking slot 22 when the external force applied to the charger 1 is greater than a certain threshold. Preferably, the charger 1 is further provided with a biasing member 13, which is clamped between the main body 11 and the connecting assembly 12, and specifically, between the main body 11 and the locking block 122. The biasing member 13 applies a force to the locking block 122, which is perpendicular to the plugging direction and towards the side of the adapter 2, so that the locking block 122 is stably retained in the locking slot 22, improving the reliability.
[0036] In some preferred embodiments, the locking block 122 is decoupled from the locking slot 22 in a direction perpendicular to the plugging direction.
[0037] In some preferred embodiments, one of the locking block 122 and the locking slot 22 is provided with a decoupling guide surface 100a, which is inclined to the plugging direction. When the external force applied to the locking block 122 is greater than a certain threshold, the locking block 122 is decoupled from the locking slot 22 along the decoupling guide surface 100a. This facilitates the decoupling of the charger 1 from the adapter 2. Preferably, the decoupling guide surface (100a) is inclined to the plugging direction by an angle greater than or equal to 40°, which facilitates the stable plugging of the charger 1 into the adapter 2, and the decoupling guide surface (100a) is inclined to the plugging direction by an angle less than or equal to 75°, which facilitates the decoupling of the charger 1 from the adapter 2, avoiding the need to apply a very large force to decouple the charger 1.
[0038] Referring to Figure 4 and Figure 5 , FIG. 4 shows a partial exploded structural schematic view of the charger in an embodiment of the present application, and FIG. 5 shows a sectional view of the charger system in an embodiment of the present application. The adapter 2 is further provided with a guiding portion 23 and a locking slot 22. The guiding portion 23 is provided with a guiding surface 23a extending obliquely from the side of the adapter 2 towards the charger 1, and a surface 23b connected with the guiding surface 23a. The surface 22b is substantially parallel to the side of the guiding portion 23, and the locking slot 22 is arranged on the guiding portion 23. Preferably, the locking slot 22 is arranged on the surface 23b.
[0039] In some preferred embodiments, the locking block 122 is biased outwardly from the opening of the connecting assembly 12 by the biasing force of the biasing member 13. During the plugging, the locking block 122 abuts against the guiding surface 23a and the surface 23b in turn as the charger 1 moves in the plugging direction until the locking block 122 is plugged into the locking groove 22 and restricts the relative movement between the charger 1 and the adapter 2. Specifically, the part of the locking block 122 that is plugged into the locking groove 22 is substantially "V"-shaped, and the locking groove 22 has a "V"-shaped groove that is shaped to receive the locking block 122. When a tripping force is applied to the charger 1 in a direction opposite to the plugging direction, the tripping force has a biasing force against the biasing force of the biasing member 13, so that the locking block 122 has a tendency to disengage from the locking groove 22. It can be understood that the operator can apply a force to the charger 1 in a direction opposite to the plugging direction after the charger 1 and the adapter 2 are connected, so as to directly disengage the charger 1 and the adapter 2. Preferably, the locking groove 22 and the locking block 122 are arranged at an end away from the plugging direction. In this way, the durability of the locking block 122 is improved, and the abrasion during abutment is reduced.
[0040] Referring to Figure 6 , FIG. 6 shows a partial exploded structural schematic view of the charger from another perspective in an embodiment of the present application. The connecting assembly 12 further comprises a base 123 that is detachably fixedly connected to the main body of the charger 1. Preferably, the base 123 is fixedly connected to the main body of the charger 1 by fasteners. The abutting portion 141 is fixedly connected to the base 123, which can be mechanically locked or integrally formed by injection molding. The bottom of the main body of the charger 1 further comprises a plurality of support legs 145 that are accommodated in a space enclosed by the main body of the charger 1 and the base 123. Advantageously, after the base 123 is detached, the charger 1 can be reliably supported on a work surface by the support legs 145.
[0041] The technical features of the above-described embodiments can be combined in any manner. To make the description concise, all possible combinations of the technical features in the above-described embodiments are not described, but as long as the combinations of the technical features do not contradict each other, they shall be considered within the scope of the present application.
[0042] The above-described embodiments only express several embodiments of the present application, and the description is relatively specific and detailed, but it shall not be construed as a limitation on the scope of the patent. It should be noted that for those skilled in the art, several modifications and improvements can be made without departing from the concept of the present application, and these shall be within the scope of protection of the present application. Therefore, the scope of protection of the patent of the present application shall be subject to the appended claims.
