[0034] In order to facilitate understanding by those skilled in the art, the structure of the present invention is further described in detail with reference to the accompanying drawings:
[0035] Embodiment 1
[0036] refer to Figure 1-6 , a highly adaptable camping projection device, comprising:
[0037] The housing is small at the top and large at the bottom and is divided into a projection part 1 and an illumination part 2 by a partition 5. A slot 11 is recessed on one side of the projection part 1, and a projection hole 12 is penetrated in the middle of the top. The upper and lower side walls of the slot 11 are penetrated with a first light-transmitting hole 111 and a second light-transmitting hole 112 corresponding to the projection hole 12;
[0038] The projection lighting assembly 3 includes a projection lens 31 disposed in the projection hole 12, a projection disk 32 inserted in the slot 11, a projection lamp 33 disposed in the second light-transmitting hole 112, and an illumination lamp 34 disposed in the middle of the partition 5. The light of the illumination lamp 34 diffuses outward through the illumination unit 2. Specifically, in this embodiment, the illumination unit 2 can be a transparent cover made of a light-transmitting material such as glass;
[0039] The electric control component 4 includes a circuit board 41 disposed in the middle of the projection part 1 and electrically connected between the projection lamp 33 and the lighting lamp 34, a button 42 disposed horizontally in one half of one side of the projection part 1 and electrically connected to the circuit board 41 at one end, and a power supply device 43 electrically connected to the circuit board 41 and vertically disposed in the middle of the other half of the projection part 1, and the other end of the button 42 penetrates through the side wall of the projection part 1 and is exposed.
[0040] The above-mentioned structure is arranged so that the on and off of the projection lamp 33 and / or the lighting lamp 34 can be controlled by the cooperation of the button 42 and the circuit board 41, so that the camping projection device can combine the functions of upward projection and lower lighting in a certain volume, and at the same time meet the needs of users for projection and lighting in the tent when camping, thereby improving the adaptability of the camping projection device; and, by arranging the projection lens 31, the projection lamp 33, the circuit board 41, and the lighting lamp 34 on the center line of the shell, arranging the projection disk 32 in the slot 11 on one side of the projection part 1, and arranging the button 42 in one half of the projection part 1, and vertically arranging the power supply device 43 in the inner middle of the other half of the projection part 1, the center of gravity of the power supply device 43 moves inward to maintain balance with the remaining components, thereby maintaining the weight balance on both sides of the projection part 1, maintaining the overall center of gravity stability of the camping projection device, improving the stability of the camping projection device placed on the floor or the table, improving the stability of projection and lighting, and reducing the risk of tipping over of the camping projection device.
[0041] In order to improve the projection diversity, the inner diameter of the second light-transmitting hole 112 gradually increases from bottom to top, the projection lamp 33 is arranged in the lower end of the second light-transmitting hole 112, the upper and lower inner walls of the slot 11 are recessed with guide grooves 113, the upper and lower middle parts of the projection disk 32 are respectively raised to form guide columns 321 corresponding to the guide grooves 113, the projection disk 32 is inserted into the slot 11 through the cooperation of the guide columns 321 and the guide grooves 113, and then rotated, a plurality of film holes 322 corresponding to the first light-transmitting hole 111 and the second light-transmitting hole 112 are circumferentially penetrated on the projection disk 32, a projection film 333 including a plurality of projection patterns corresponding to the plurality of film holes 322 is embedded in the projection disk 32, a plurality of adjustment grooves 334 are circumferentially recessed on the outer wall of the projection disk 32, and the projection disk 32 is exposed on one side away from the bottom of the slot 11. Therefore, the projection disk 32 can be rotated by the exposed adjustment slot 334 so that different film holes 322 correspond to the first light transmission hole 111 and the second light transmission hole 112, so that the projection lens 31 can project different patterns, thereby improving the diversity and interest of projection.
[0042] In order to further improve the stability of the camping projection device, the power supply device 43 includes a plurality of batteries arranged side by side in the middle of the rear half of the projection unit 1, the rear lower end of the lighting unit 2 is provided with a support foot 21 corresponding to the power supply device 43, and the bottom of the lighting unit 2 is provided with a counterweight 22. Specifically, the counterweight 22 can be a solid high-density structure or a hollow structure filled with heavy objects. Thus, under the premise of moving the center of gravity of the power supply device 43 inward, the auxiliary support of the support foot 21 improves the stability of the entire shell and reduces the risk of backward tilting. At the same time, the center of gravity of the entire camping projection device is moved inward and downward by the setting of the counterweight 22 protruding from the inner bottom, which further improves the stability of the center of gravity of the entire camping projection device and reduces the risk of tipping over.
[0043] When the camping projection device is placed on the ground or on a table in a tent, there will be a large amount of flammable fabrics in the tent. Therefore, in order to avoid the bottom of the lighting part 2 being overheated by the lighting lamp 34 when the camping projection device is used for a long time, resulting in a fire hazard, the counterweight part 22 is arched and the top surface is set as a refractive surface 221. The refractive surface 221 is used to refract the light of the lighting lamp 34 and diffuse it outward through the side wall of the lighting part 2. The refractive surface 221 is made of an opaque material to avoid the refractive surface 221 being too glaring when used. The addition of the refractive surface 221 allows the light to be refracted and diffused outward before reaching the bottom of the lighting part 2, thereby avoiding the occurrence of a fire hazard caused by overheating of the bottom of the lighting part 2 that contacts the flammable materials inside the tent, thereby improving the safety of the use of the projection camping lamp.
[0044] In order to improve the convenience of the camping projection device, a handle 7 is further included, both ends of which are rotatably connected to the projection unit 1. Therefore, when the projection function is not used or the camping projection device is carried, the camping projection device can be hung or carried by hand through the handle 7, thereby improving the convenience of use.
[0045] Embodiment 2
[0046] refer to Figure 7-9 The difference between this embodiment and the first embodiment is that:
[0047] In order to improve the functionality of the camping projection device, a plurality of light-transmitting gaps 26 are provided in the circumferential direction of the lighting part 2, a power grid 6 is provided at the bottom of the partition 5 and is covered on the outside of the lighting lamp 34, the power grid 6 is electrically connected to the circuit board 41, and a collecting groove 23 is provided at the outer periphery of the counterweight part 22 in the annular depression at the bottom of the lighting part 2. Thus, by providing the power grid 6, when there are mosquitoes in the tent, they will be attracted by the lighting lamp 34 to enter the lighting part 2, and after being electrocuted by the power grid 6, they will slide down along the refractive surface 221 to the collecting groove 23, so as to achieve the function of removing mosquitoes in the tent, improve the functionality of the camping projection device, and prevent the dead mosquitoes from affecting the lighting effect.
[0048] In order to improve the adaptability and safety of the lighting unit 2, the top of the lighting unit 2 is open and can be detachably arranged with the projection unit 1. The side wall of the lighting unit 2 is set as a double-layer structure and includes an inner fixed layer 24 and an adjustment layer 25 that is rotatably arranged on the outer side of the fixed layer 24. The fixed layer 24 includes a plurality of vertically extending and circumferentially spaced light shielding ribs 241, and the adjustment layer 25 includes a plurality of vertically extending and circumferentially spaced light shielding plates 251. A plurality of light-transmitting gaps 26 are formed between the plurality of light-transmitting ribs 241 and the plurality of light shielding plates 251. The overlapping gaps between the plurality of light shielding plates 251 and the plurality of light-transmitting ribs 241 are adjusted to adjust the width of the light-transmitting gaps 26 of the lighting unit 2. Thus, by adjusting the width of the light-transmitting gaps 26 to meet different lighting brightness requirements, the adaptability of the brightness of the lighting unit 2 is improved. At the same time, when children are camped and the power grid 6 is working, the size of the light-transmitting gaps 26 can be reduced to prevent children from accidentally touching the power grid 6 and being injured, thereby improving the safety of the lighting unit 2.
[0049] In order to improve the adjustment range of the light-transmitting gap 26, the width of the light-shielding plate 251 is greater than the width of the light-shielding ribs 241, the number of the light-shielding plates 251 and the light-shielding ribs 241 is the same, and the spacing between adjacent light-shielding ribs 241 is greater than the width of the light-shielding plates 251. Thus, the width difference between the light-shielding plates 251 and the light-shielding ribs 241 is increased, thereby increasing the maximum width of the adjustment gap, increasing the adjustment range of the light-transmitting gap 26, and further improving the adaptability of the lighting unit 2.
[0050] It should be pointed out that the implementation principle and technical effects of this embodiment are the same as those of Embodiment 1. For the sake of brief description, for matters not mentioned in this embodiment, reference may be made to the corresponding contents in Embodiment 1.
[0051] The above description is only the preferred implementation of the utility model, and is not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
