[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0023] like Figure 1-6 As shown, the utility model provides a key chain with an LED light, which is not only used as a key chain, but also can be used for lighting through the LED light. Its specific structure mainly includes a hollow shell. The shell serves as the outer structure of the entire key chain, and is usually formed by assembling a base 101 and a cover 102. The internal hollow position is used to place the key chain lighting accessories and protect them.
[0024] When the base 101 and the cover body 102 are assembled, the two are connected and fixed by plugging. Four slots 103 are provided on the base 101. Correspondingly, four insertion rods 104 that are inserted into the corresponding slots 103 are provided on the plugging side of the cover body 102 and the base 101. After plugging, the base 101 and the cover body 102 are in close contact and fixed on all sides.
[0025] After the base 101 and the cover body 102 are connected, in order to enhance the sealing after the connection on all sides, the base 101 is provided with a fitting portion 105 protruding and fitting against the inner wall of the cover body 102 on all sides, and a sealing strip is added at the connection between the base 101 and the cover body 102 to enhance the sealing and also have a waterproof effect. The sealing strip 13 can be made of soft silicone and is adhered to the outside of the fitting portion 105 and close to one end of the base 101 by gluing.
[0026] A main control circuit board 2 and a main control chip 3 integrated and welded on the surface of the main control circuit board 2 are provided in the base 101. An LED lamp 4 projecting outward and connected to the internal main control circuit board 2 is provided at one end of the shell. The main control circuit board 2 with the main control chip 3 integrated is the main control component inside the key chain. All components that are powered and controlled need to be connected to the main control circuit board 2 and be conductive. The LED lamp 4 at the front end of the shell is controlled by the main control circuit board 2 to light up or dim. A placement hole for assembling and partially ejecting the LED lamp 4 is provided at the front end of the shell. The hole is provided at the connection between the base 101 and the cover 102, and is conductive inside and outside.
[0027] A battery holder 14 is connected to the surface of the main control circuit board 2, and the battery holder 14 is equipped with a detachable battery body 15 connected to the main control circuit board 2. The battery body 15 uses a rechargeable lithium battery, which can be cyclically charged to power the LED lamp 4. The user can also directly replace the battery body 15 to power the internal power supply.
[0028] A groove 6 is provided on the surface of the cover body 102, a second protrusion 8 is provided in the middle of the groove 6, a push switch 9 and a charging port 10 both connected to the main control circuit board 2 are provided on the surface of the second protrusion 8, a push switch 9 for controlling the lighting and dimming of the LED light 4 is provided on the surface of the cover body 102, which saves more space, and a charging port 10 for charging the battery body 15 inside the shell is provided at the same time, and the user only needs to plug the charging cable into the charging port 15 to charge the battery body 15.
[0029] In addition, a silicone sheet 11 filling the entire groove 6 and covering the second protrusion 8, as well as a first protrusion 7 connected to the silicone sheet 11 and arranged on one side of the groove 6 is provided on the surface of the cover body 102. The top of the silicone sheet 11 filled in the groove 6 is horizontally aligned with the cover body 102, which can well protect the push switch 9 and the charging port 10 on the surface of the second protrusion 8 from damage. A notch 17 is also provided on the surface of the cover body 102, the side of which is connected to the groove 6. The user can lift the silicone sheet 11 through the notch 17 and then perform the corresponding operations of the push switch 9 and the charging port 10.
[0030] The surface of the cover body 102 is also provided with a first protrusion 7 located on one side of the groove 6. The first protrusion is mainly used to connect the silicone sheet 11 to prevent it from falling off and being lost. A T-shaped groove 16 is provided inside the first protrusion, and the silicone sheet 11 is provided with a connecting portion 12 connected to the first protrusion. The connecting portion 12 is inserted into the first protrusion 7 and fixed, and one end of the insertion is in a T shape matching the T-shaped groove 16, and is directly stuck in the T-shaped groove 16 and fixed. Since the silicone sheet 11 is a soft material, it does not affect the operation of raising or closing the silicone sheet 11.
[0031] A hole 5 penetrating both the base 101 and the cover 102 is provided at the rear end of the housing. The inner wall of the hole 5 is also sealed, and the user can hang the keychain through the hole 5 for use.
[0032] Compared with traditional technology, this technical solution provides a key chain with an LED light 4, and the user can enable the LED light 4 to achieve the lighting effect in a dark environment. In addition, a silicone sheet 11 is added to the outer shell surface of the key chain to completely cover the control and connect the function keys of the LED light 4, which effectively protects the functional interface of the key chain surface and extends the service life of the key chain.
[0033] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or basic features of the present invention. Therefore, no matter from which point of view, the embodiments should be regarded as exemplary and non-restrictive, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims are included in the present invention, and any figure mark in the claims should not be regarded as limiting the claims involved.
