Therefore, they should not be construed as limitations on this utility model.

[0048] Example 1

[0049] like Figure 1 and Figure 2 As shown, the present invention proposes a portable and drop-resistant mobile lighting lamp, including a lamp post 1, a lamp body 2 located at the upper end of the lamp post 1, and a base 3 located at the lower end of the lamp post 1. The lamp post 1 is provided with a height adjustment structure 4 for adjusting the height of the lamp body 2. The height can be adjusted within the range of 1.3 meters to 2.5 meters to meet the height requirements of different usage scenarios.

[0050] To improve drop resistance, refer to Figure 3 and Figure 4 As shown, this application designs an anti-fall support device 5, which includes a slide 51 that slides up and down along the lamp post 1, a support leg 52 hinged to the outer wall of the slide 51, and a fixing component 53. The support leg 52 is used to unfold and retract, and the fixing component 53 is used to fix the position of the support leg 52 after it is unfolded.

[0051] refer to Figure 5 and Figure 6 As shown, the fixing component 53 includes:

[0052] Primary fixing part 531: located at the hinge between slide 51 and support leg 52;

[0053] Secondary fixing part 532: It is a snap-on fixing part, which is installed between the slide 51 and the lamp post 1. After the height of the slide 51 is adjusted, that is, after the tail end of the support leg 52 contacts the ground to form a triangular support, the snap-on fixing part is used to fix the position of the slide 51 on the lamp post 1 to prevent the support leg 52 from moving.

[0054] The third-level fixing part 533 is a limiting bracket. A limiting seat 11 is provided above the battery compartment 61. (Refer to...) Figure 7 As shown, a positioning hole 521 is provided in the middle section of the inner wall of the support leg 52. The limiting bracket is Ω-shaped and one end is hinged to the outer wall of the limiting seat 11. The limiting seat 11 is provided with a hinged limiting bracket, and the other end of the opening is detachably locked in the positioning hole 521 to support the support leg 52 and realize the positioning and support of the support leg 52 when it is unfolded. The limiting bracket is made of metal and can be slightly deformed so that the opening is locked in the positioning hole 521.

[0055] In this embodiment, the support legs 52 comprise three sets evenly spaced on the outer circumference of the slide block 51. The support legs 52 are made of high-strength alloy material, preferably aluminum-plastic composite material, forming a composite structure with high strength, lightweight, corrosion resistance, and good formability. A manual handle 54 is also provided on the outer side of each support leg 52. Additionally, an anti-slip contact portion can be provided at the end of each support leg 52 to ensure friction when in contact with the ground.

[0056] The unfolding process is as follows:

[0057] By manually gripping the outrigger 52 with the handle 54 and operating the secondary fixing part 532, the lock on the outrigger 52 is released.

[0058] Manually pushing the slide block 51 downwards causes the three legs 52 below to open outwards simultaneously, with the legs 52 radiating outwards around the lamp post 1;

[0059] When the outrigger 52 is extended to the preset angle, that is, the angle that ensures support stability, the open end of the limiting bracket is inserted into the positioning hole 521, and the secondary fixing part 532 is adjusted to the locked state. The outrigger 52 and the light pole 1 are rigidly fixed through the hole matching. At this time, the ends of the three outriggers 52 are supported on the ground, forming a triangular stable structure. The radial distribution of the triangular bracket combined with the anti-slip design at the end greatly improves the anti-tipping ability of the equipment on uneven outdoor ground or in windy environments.

[0060] The storage process is as follows:

[0061] Reverse the operation of the secondary fixing part 532, release the limit, remove the limit bracket from the positioning hole 521, and store it in the inner cavity of the outrigger 52 by rotation;

[0062] By pulling the slide block 51 upwards, the three brackets are moved to retract towards the lamp post 1;

[0063] Once the outrigger 52 is fully retracted, lock the secondary fixing part 532, retract the lamp post 1, and complete the storage.

[0064] Example 2

[0065] refer to Figure 1 and Figure 8 As shown, in order to solve the problem of battery life, based on embodiment 1, this application also includes a power switching system 6. The power switching system 6 includes a battery compartment 61 disposed on the base 3. The battery compartment 61 is provided with two detachable power supply batteries 62. A power switching module 63 is provided between the two power supply batteries 62 to switch between them by comparing the voltage of the power supply batteries 62.

[0066] The battery compartment 61 has an opening on one side and a cover 611 is hinged at the opening. A snap-fit ​​structure is provided between the cover 611 and the outer wall of the battery compartment 61 to fix the battery compartment 61 to the cover 611. The battery compartment 61 adopts a side pull-out design for easy battery replacement.

[0067] like Figure 9As shown, the power switching module 63 includes a power switch circuit 631 and a voltage comparison circuit 632. One end of the power switch circuit 631 is connected to the power supply battery 62 and the other end is connected to the load lamp body 2. The power switch circuit 631 is composed of two sets of MOSFETs connected in series. The two ends of the voltage comparison circuit 632 are respectively connected between the MOSFETs close to the power supply battery 62.

[0068] As a preferred embodiment, the power supply battery 62 is provided with two sets of power supply 621 and power supply 622 respectively. The power switching circuit 631 includes a first power switching circuit connected in series between power supply 621 and the load, and a second power switching circuit connected in series between power supply 622 and the load. The first power switching circuit includes MOSFET 1 and MOSFET 2, and the second power switching circuit includes MOSFET 3 and MOSFET 4. The voltage comparison circuit 632 is connected between MOSFET 1 and MOSFET 3 to control the opening or closing of MOSFET 1 and MOSFET 3, so that power supply 621 or power supply 622 supplies power to the load.

[0069] Among them, MOSFET 1 and MOSFET 2 are P-channel MOSFETs, and MOSFET 3 and MOSFET 4 are N-channel MOSFETs.

[0070] In this embodiment, when the power of one of the power supply batteries 62 is close to being depleted (a preset threshold, such as 10% remaining), the switching unit of the power management module automatically turns on the power supply circuit of the other power supply battery 62, while disconnecting the circuit of the battery compartment 61 that is about to be depleted, so that there is no power interruption during the switching process.

[0071] As a further example:

[0072] The lamp post 1 is equipped with a control handle on the outside, which has control buttons for easy portability and use.

[0073] It should be noted that the lamp body 2 uses LED beads and light-diffusing material, and the lamp post 1 adopts a segmented telescopic rod structure for adjusting the lighting height, such as... Figure 3 As shown, the lamp body 2 is composed of multiple sets of hinged and flipping lamp petals. The angle of the four lamp petals can be adjusted uniformly: when fully extended, it forms a 120° wide-angle illumination surface, which evenly illuminates the flat ground; when converged, it forms a 360° ring projection, covering the surrounding walls.

[0074] The device weighs 6.5kg, which is relatively light and easy to carry and install. It combines aluminum and high-strength plastic, which ensures structural stability and durability while reducing the overall weight and increasing ease of use.

[0075] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
