DETAILED DESCRIPTION

[0023] 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.

[0024] See also Figure 1-4 In this embodiment, a children's bicycle lamp with an insert projection function includes a bicycle lamp body 1, an insert block 101, a lithium battery 2, a circuit board 3 and a control panel 4. A projection mechanism is arranged inside the bicycle lamp body 1, and a ventilation component is arranged outside the bicycle lamp body 1.

[0025] Embodiment 1: The projection mechanism includes an illumination lamp 5 and a cylinder 6 fixedly connected to a bicycle lamp body 1, a projection lamp 7 is fixedly installed inside the cylinder 6, a projection lens 8 is fixedly installed inside the left end of the cylinder 6, a projection plug 9 plugged into the bicycle lamp body 1 is plugged into the cylinder 6, a through groove is provided at the top of the cylinder 6 and the top of the bicycle lamp body 1, the projection plug 9 is plugged into the cylinder 6 and the bicycle lamp body 1 through the through groove, it is convenient to disassemble and replace the projection plug 9, it is convenient for the user to replace the projection content and perform projection display of different contents, the projection plug 9 is located on the left side of the projection lamp 7, the projection lens 8 is located on the left side of the projection plug 9, the projection lamp 7 is powered on to generate bright light to illuminate the projection plug 9, and the content on the projection plug 9 is projected and displayed through the projection lens 8.

[0026] Among them, the top of the projection insert 9 is fixedly connected with a limit seat 10 which is sleeved with the insert block 101. An installation groove is provided inside the limit seat 10. The limit seat 10 is sleeved with the insert block 101 through the installation groove. The limit seat 10 and the projection insert 9 are limited by the insert block 101, thereby reducing the left and right sliding of the projection insert 9 and improving the projection effect. The limit seat 10 is rotatably connected with a knob 11 inside. The knob 11 is fixedly connected with a screw rod 12 inside. The screw rod 12 is threadedly connected with a sliding seat 13 outside. An installation hole is provided inside the limit seat 10. The knob 11 is rotatably connected with the limit seat 10 through the hole, which facilitates the installation of the knob 11. When the user rotates the knob 11, the knob 11 drives the screw rod 12 to rotate, so that the sliding seat 13 moves up and down outside the screw rod 12, which is convenient for the user to use.

[0027] In addition, pull rods 14 are hinged on the left and right sides of the sliding seat 13, and the other end of the pull rod 14 is hinged with a limit block 15 which is slidably connected to the limit seat 10. A limit groove is provided inside the plug block 101, and the size of the limit block 15 is adapted to the limit groove. The limit block 15 is clamped with the plug block 101 through the limit groove. The sliding seat 13 drives the pull rod 14 to move downward, so that the limit block 15 is clamped with the plug block 101, and the limit seat 10 and the projection insert 9 are limited and fixed, thereby reducing the loosening and falling off of the projection insert 9.

[0028] It should be noted that, by setting up the projection mechanism, the bicycle light has added a limiting structure, which is convenient for limiting and fixing the projection film, reduces the sliding and falling off of the projection film, improves the projection effect of the bicycle light, and solves the problem that the bicycle light does not have a limiting structure, and it is inconvenient to limit and prevent the projection film from falling off during the use of the bicycle light, which easily causes the projection film to slide or fall off during use, resulting in the loss of the projection film and affecting the projection effect of the bicycle light.

[0029] Specifically, during the use of the children's bicycle light with the insert projection function, the user plugs the projection insert 9 into the bicycle light body 1 and the cylinder 6, and completes the socket connection between the limit seat 10 and the insert block 101. Then, the user turns the knob 11, and the knob 11 drives the screw rod 12 to rotate, so that the sliding seat 13 moves downward outside the screw rod 12, and the sliding seat 13 drives the pull rod 14 to move downward, so that the limit block 15 is engaged with the insert block 101, and the limit seat 10 and the projection insert 9 are limited and fixed, thereby achieving the purpose of reducing the loosening and falling off of the projection insert 9 and improving the projection effect of the bicycle light.

[0030] Example 2: Please refer to Figure 3-4 The ventilation assembly includes two ventilation nets 16 fixedly connected to the bicycle lamp body 1. The front and back of the bicycle lamp body 1 are fixedly connected with rain covers 17. The position of the rain cover 17 corresponds to the position of the ventilation net 16. The size of the rain cover 17 is larger than the ventilation net 16. When the bicycle lamp is in use, the air inside and outside the lamp circulates through the ventilation net 16, which is convenient for heat dissipation inside the bicycle lamp body 1. At the same time, the rain cover 17 reduces the entry of rainwater into the interior of the bicycle lamp body 1 through the ventilation net 16, thereby increasing the safety of the bicycle lamp body 1.

[0031] It should be noted that by providing the ventilation assembly, ventilation and heat dissipation of the bicycle light are facilitated, and the use of the bicycle light is facilitated.

[0032] Specifically, when the bicycle light is in use, air inside and outside the light circulates through the ventilation net 16 to facilitate heat dissipation inside the bicycle light body 1. At the same time, the rain cover 17 reduces rainwater from entering the interior of the bicycle light body 1 through the ventilation net 16.

[0033] The working principle of the above embodiment is:

[0034] (1) During the use of the children's bicycle light with the insert projection function, the user inserts the projection insert 9 into the bicycle light body 1 and the cylinder 6, and completes the sleeve connection between the limit seat 10 and the insert block 101. Then, the user rotates the knob 11, and the knob 11 drives the screw rod 12 to rotate, so that the sliding seat 13 moves downward outside the screw rod 12, and the sliding seat 13 drives the pull rod 14 to move downward, so that the limit block 15 is engaged with the insert block 101, and the limit seat 10 and the projection insert 9 are limited and fixed, thereby achieving the purpose of reducing the loosening and falling off of the projection insert 9 and improving the projection effect of the bicycle light.

[0035] (2) When the children's bicycle light with the insert projection function is in use, the air inside and outside the light circulates through the ventilation net 16, which facilitates the heat dissipation inside the bicycle light body 1. At the same time, the rain cover 17 reduces the amount of rainwater that enters the interior of the bicycle light body 1 through the ventilation net 16.
