[0026] In the same manner, the lamp body 1 of the present invention is provided with an inductive contact pin 13, and the charging bag 2 is provided with a corresponding inductive contact piece 24, and only when the inductive contact pin 13 is in contact with the inductive contact piece 24, the charging bag 2 is Powering the lamp body 1.

[0027] When the charging package 2 is inserted into the lamp body 1 吋, if the charging package 2 is not fully inserted into the lamp body 1, the USB plug 23 will only be partially inserted into the first USB socket 14, and the There is a certain virtual connection, which causes the charging package 2 to be unstable to the power supply of the lamp body 1, thereby causing damage to the lamp body 1. By providing the sensing stylus 13 and the sensing contact 24, a double fuse is formed. Only when the USB plug 23 is fully inserted into the first USB socket 14, and the sensing stylus 13 is in contact with the sensing contact 24, the charging package 2 is The lamp body 1 will be powered to avoid damage to the lamp body 1. At the same time, other charging packages that do not meet the specifications can be avoided. 2 The lamp body 1 is powered. The lamp body 1 is damaged due to the mismatch between the model and the performance.

[0028] In this embodiment, the charging package 2 further includes a second USB socket 25, and the second USB socket 25 is connected to the second control board 22, and the second USB socket 25 is used to supply power to the external device.

[0029] In this embodiment, the charging package 2 is provided with a second USB socket 25, and the second USB socket 25 can be used to connect the hand. An external device such as a machine can be powered as a mobile power source. The second USB socket 25 is mounted on one end of the charging package 2 away from the lamp body 1, so that the charging package 2 can supply power to the external device even if it is connected to the lamp body 1. The user can choose whether to remove the charging package 2 and use it separately according to the actual situation.

[0030] In this embodiment, the outer casing of the lamp body 1 and the charging bag 2 are integrally formed, and the waterproof effect of the single lamp body 1 or the charging bag 2 is good, but because the bottom of the groove 15 on the lamp body 1 The protruding sensing probe and the first USB socket 14 are provided, and the charging package 2 also has a through hole 26 and a USB plug 23, which undoubtedly weakens the waterproof effect of the connection between the lamp body 1 and the charging bag 2. In this embodiment, a sealing ring 27 is disposed on the outer side wall of the charging bag 2. When the charging bag 2 is inserted into the recess 15 of the recess 15, the sealing ring 27 cooperates with the inner side wall of the recess 15 to form a sealing structure to enhance the lamp body 1 and Waterproof effect at the junction of the charging bag 2.

[0031] In order to make the contact effect between the inductive contact pin 13 and the inductive contact piece 24, the inductive contact pin and the inductive contact piece 24 are in contact with each other, and the inductive contact pin 13 will push the inductive contact piece 24 to bend it. angle. However, after the metal is bent a plurality of times, the metal is fatigued, so that the sensing contact pin 24 cannot be restored to the original position after the sensing contact pin 24 is separated from the sensing contact piece 24, and even the lamp body 1 is connected with the charging bag 2, and the sensing contact pin 13 The contact with the inductive contact 24 cannot be reached. In this embodiment, the inductive contact 24 includes a first connecting portion 241, a second connecting portion 24 2 and a third connecting portion 243 which are sequentially connected. The first connecting portion 241 is perpendicular to the second connecting portion 242 in a first direction. The third connecting portion 243 is perpendicular to the second connecting portion 242 in the second direction, and the third connecting portion 243 is connected to the second control board 22. The inductive contact piece 24 has a shape resembling an I-shape, and such a shape makes the inductive contact piece 24 more elastic. The inductive contact 24 is not fatigued by multiple bends, and the useful life of the inductive contact 24 is extended.

In the embodiment, the connection of the first connecting portion 241, the second connecting portion 242, and the third connecting portion 243 is curved. The elasticity of the inductive contact 24 is further increased to increase its useful life.

[0033] In this embodiment, the length ratio of the first connecting portion 241, the second connecting portion 242, and the third connecting portion 243 is 1:1:

2. The first connecting portion 241 is for contacting the sensing contact pin 13, and the third connecting portion 243 is connected to the second control board 22, and when the sensing contact pin 13 is used to move the first connecting portion 241, because the third connecting portion 243 is longer than the first The connecting portion 241 is parallel to each other, so that the third connecting portion 243 is more likely to be deflected, so that the first connecting portion 241 is less likely to be deformed, thereby affecting its contact with the sensing probe. The ratio of the length of the first connecting portion 241 plus the third connecting portion 243 to the second connection is 3:1, and both are perpendicular to the second connecting portion 242, forming two right-angled sides of the triangle, which are subjected to force It is more stable and there will be no excessive local stress.

[0034] In this embodiment, in order to cause the inductive contact pin 13 to move the inductive contact piece 24, the damage to the inductive contact piece 24 is minimized. When the inductive contact pin 13 abuts the inductive contact piece 24, the first connecting portion 241 has an offset angle of 3°-8°. Within this range of angles, the inductive contact 24 does not easily cause metal fatigue even if it is bent multiple times in succession, greatly increasing the useful life of the inductive contact 24. Further, in this embodiment, an optimum value is selected. When the inductive contact pin 13 abuts the inductive contact piece 24, the first connecting portion 241 has an offset angle of 5°. The damage of the inductive contact pin 24 to the inductive contact 24 is minimized.

[0035] In this embodiment, the inductive contact piece 24 is made of spring steel. Spring steel has good elasticity and is not prone to metal fatigue. Even if the inductive contact piece 24 is frequently bent, metal fatigue will not easily occur.

[0036] In this embodiment, the end surface of the inductive stylus near the end of the inductive contact piece 24 is a curved surface. Because the inductive contact pin 13 is to be bent to invert the inductive contact piece 24 so that the two sides are not perpendicular to each other, the end surface of the inductive contact pin 13 is a curved surface, so that even if the inductive contact pin 13 and the inductive contact piece 24 are not perpendicular to each other It also ensures that the contact area of the contact surface is sufficient and the contact effect is good. At the same time, even if the metal contact of the inductive contact piece 24 causes the angle between the contact pin 13 and the inductive contact piece 24 to change, the contact area of the contact surface is sufficient and the contact effect is good.

In this embodiment, a rear cover 3 is further included, and the rear cover 3 is connected to the lamp body 1 for fixing the charging package 2 to prevent the charging package 2 from being detached from the lamp body 1.
