Modes for Carrying Out the Invention

[0035] To facilitate understanding of the present invention, the present invention will be described more fully below with reference to the accompanying drawings. The accompanying drawings illustrate preferred embodiments of the present invention. However, the present invention may be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to provide a more thorough and comprehensive understanding of the present disclosure.

When an element is referred to as being "connected to" another element, it may be directly connected to the other element or there may be an intermediate element. The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only implementation methods.

[0037] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the art to which this invention pertains. The terms used in this specification of the present invention are for the purpose of describing specific embodiments only and are not intended to limit the present invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0038] 1 and 2 , the present invention provides a luggage compartment lighting lamp 10 , including a lamp housing 100 , a lamp head 200 , a telescopic pull rod 300 , and an unfolding mechanism 400 .

[0039] The telescopic rod 300 is connected to the outer wall of the light box 100. The lamp head 200 is located on the telescopic rod 300. A spiral cable 500 is provided between the lamp head 200 and the light box 100. The spiral cable 500 electrically connects the lamp head 200 to the light box 100 and is itself telescopic, extending and contracting with the telescopic rod 300. The electronic components of the luggage compartment lighting 10, including the control panel, battery, display 110, and control buttons 120, are all housed in the light box 100. The lamp head 200 is designed to be separate from the light box 100, achieving electrical and thermal isolation. It should be noted that the lamp holder 200 generates heat when it is lit. If the lamp holder 200 and the battery are placed on the light box 100 together, this heat will increase the internal temperature of the light box 100, thereby affecting the charging and discharging of the battery. Therefore, by separating electricity and heat, the lamp holder 200 can be placed externally to obtain better heat dissipation effect, and it also avoids the heat generated by the lamp holder 200 interfering with the normal charging and discharging of the battery inside the light box 100, making the luggage box lighting lamp 10 safer.

[0040] Please refer to Figure 7. The unfolding mechanism 400 includes a base 410, a sliding bracket 420 and a balancing swing arm 430. The base 410 is provided with a storage channel 411. The sliding bracket 420 is slidably disposed in the storage channel 411. The end of the sliding bracket 420 exposed outside the storage channel 411 is provided with a wheel 421, and the storage channel 411 is not connected to the light box 100. External foreign matter cannot enter the light box 100 through the storage channel 411, thereby maintaining the sealing of the light box 100. The sliding bracket 420 and the balancing swing arm 430 are both stored in the base 410. After the trunk-type lighting 10 is transported to the destination, the sliding bracket 420 and the balancing swing arm 430 are unfolded to increase the grip of the trunk-type lighting 10 and avoid collapse during use.

[0041] It should be emphasized that the trunk-type lighting lamp 10 is mainly used in outdoor scenes such as emergency and rescue. The places that need lighting are often places with poor road conditions and cannot be reached directly by vehicles. Usually, rescue tools need to be carried to the destination by manpower. In the above embodiment, wheels 421 are provided on the sliding bracket 420. The user holds the telescopic pull rod 300 to tilt the trunk-type lighting lamp 10 so that the wheels 421 touch the ground, and drags the trunk-type lighting lamp 10 to the destination, which can make the transportation process more labor-saving.

[0042] Referring to Figure 7 , the balancing arm 430 includes a rod 431, a rotating shaft 432, and a support shaft 433. The rotating shaft 432 is mounted on the base 410, and the rod 431 is rotatably mounted on the rotating shaft 432. The support shaft 433 is located on the end of the rod 431 away from the rotating shaft 432. When not deployed, the balancing arm 430 is stored within the base 410, reducing the size of the luggage compartment light 10, preventing it from being scratched by foreign objects during transportation, and allowing the luggage compartment light 10 to pass through narrow passages. The rotating shaft 432 serves as the rotation center of the rod 431. Turning the balancing arm 430 causes the rod 431 to rotate about the rotating shaft 432, flipping the support shaft 433 to the outside of the base 410, forming a fulcrum away from the center of the light box 100 (as shown in Figure 9 ), thereby increasing the luggage compartment light 10's anti-tilt capability.

[0043] Preferably, referring to Figure 7, the positions of the rotating shaft 432 and the supporting shaft 433 that contact the ground are provided with foot pads 434. The foot pads 434 are made of wear-resistant soft rubber, which can further improve the grip of the luggage compartment lighting lamp 10 and prevent it from sliding.

[0044] After securing the trunk-type lighting lamp 10 at the destination, the telescopic rod 300 can be pulled out to raise the lamp head 200 for a wider illumination range. After completing the illumination task, the telescopic rod 300 can be retracted for easy storage. As can be seen from the above-described use process of the trunk-type lighting lamp 10, in order to meet the lighting needs during rescue and emergency operations, it is necessary to adjust the fixed height of the lamp head 200. However, conventional telescopic rods 300 generally have knobs provided between the rod bodies at each level. After adjusting the telescopic rod 300 to the target length, the knobs are tightened, and the friction generated during tightening is used to secure the rod. This requires turning the knobs to extend and retract the telescopic rod 300. Moreover, after repeated use, the outer wall of the rod will wear, making it impossible to fully lock the telescopic rod 300. Furthermore, the knobs need to be turned to contact and lock the telescopic rod 300 when extending or retracting the telescopic rod 300, which is a cumbersome operation. During emergency and rescue operations, users may easily forget to turn the knobs, causing the telescopic rod 300 to fall after extension, thereby damaging the lamp head 200. Therefore, how to make the extension and retraction process of the telescopic rod 300 easier to operate and automatically lock the telescopic rod 300 after extension to prevent the lamp head 200 from accidentally falling off is a problem that needs to be solved.

[0045] To solve the above problems, please refer to Figures 3, 4 and 6. The telescopic rod 300 includes a handle 310, a trigger member 320 and a telescopic tube body 330. The trigger member 320 passes through the telescopic tube body 330. The telescopic tube body 330 includes a plurality of hollow tubes 331 nested together in sequence. The diameter of each hollow tube 331 increases from the inside to the outside (that is, the diameter of the inner hollow tube 331 is smaller than the diameter of the outer hollow tube 331). A limiting hole 331a is provided on the hollow tube 331. The bottom of the hollow tube 331 is provided with a fixing sleeve 332 and a push block 333, a tube pull pin 334 and a first spring 335 located on the fixing sleeve 332. The first spring 335 is used to push the tube pull pin 334 so that the tube pull pin 334 is in close contact with the tube wall of the hollow tube 331. When the telescopic tube body 330 is extended, the pull-tube pin 334 is aligned with the limiting hole 331a on the other hollow tube 331, and the first spring 335 pushes the pull-tube pin 334 into the limiting hole 331a, thereby locking the hollow tube 331 in the expanded state. The push block 333 is provided with a pressing portion 333a and a guiding inclined surface 333b. The pressing portion 333a is exposed outside the fixing sleeve 332 (as shown in Figure 5). When the push block 333 is pressed down, the guiding inclined surface 333b can push the pull-tube pin 334 to move horizontally, so that the pull-tube pin 334 is pulled out of the limiting hole 331a, thereby releasing its lock on the two adjacent hollow tubes 331, allowing the hollow tubes 331 to retract.

[0046] Please refer to Figures 3 and 4. The trigger member 320 includes a first button 321, a pull line 322 and a pressing seat 323. The first button 321 is arranged on the handle 310. The pull line 322 passes through the telescopic tube body 330, and the pull line 322 is located in the inner cavity of the innermost hollow tube 331. The pressing seat 323 is arranged at the end of the pull line 322, and the pressing seat 323 is used to press the push block 333.

[0047] The principle of telescopic pull rod 300 is as follows:

[0048] When the telescopic pull rod 300 needs to be switched from the retracted state to the extended state, the handle 310 is held and force is applied to pull the telescopic tube body 330. The inner hollow tube 331 extends from the outer hollow tube 331. During this process, the inner hollow tube 331 slides along the tube wall of the outer hollow tube 331. When the inner hollow tube 331 is extended to the limit position, the pull-tube pin 334 on it pops out and fits into the limiting hole 331a on the outer hollow tube 331. The pull-tube pin 334 cooperates with the limiting hole 331a to lock the adjacent hollow tubes 331 together. The telescopic tube body 330 can be extended by applying a pulling force. After being extended to the limit position, it is automatically locked by the pull-tube pin 334 without the need for additional operation by the user.

[0049] When the telescopic pull rod 300 needs to be switched from the extended state to the retracted state, hold the handle 310 and press the first button 321, and apply pressure to the handle 310. At this time, the first button 321 will push the pull line 322 toward the bottom of the hollow tube 331, allowing the pressing seat 323 to squeeze the push block 333, driving the guiding slope 333b on the push block 333 to push the pull pin 334, causing the pull pin 334 to retract, thereby releasing its lock on the hollow tube 331; then, forcefully press the handle 310 to drive the hollow tube 331 on the inside to retract into the adjacent hollow tube 331. If the external force is removed at this time, the lamp head 200 will stay at the hollow tube 331 at this level, and will be in contact with the hollow tube below. 331 remains in an extended state, so that after the lamp head 200 is adjusted to the target height, the external force can be removed to fix it without additional operation, making the process of adjusting the height of the lamp head 200 more convenient; if the downward pressure is maintained at this time, the fixing sleeve 332 at the bottom of the inner hollow tube 331 will press the push block 333 on the outer hollow tube 331, thereby retracting the pull tube pin 334 in the outer hollow tube 331, causing the hollow tube 331 to retract into the hollow tube 331 of the next level until all the hollow tubes 331 are nested together.

[0050] When the telescopic tube body 330 is extended, the hollow tube 331 located in the inner layer is pulled out first, and the next-level hollow tube 331 begins to be pulled out only after the tube-pulling pin 334 pops out and locks the hollow tube 331; when the telescopic tube body 330 is contracted, the tube-pulling pin 334 on the inner layer hollow tube 331 is triggered first, and the outer layer hollow tube 331 begins to retract only after the inner layer hollow tube 331 retracts into place, that is, when the telescopic tube body 330 is extended and contracted, the inner layer hollow tube 331 responds first, and the extension and contraction processes are both carried out from the inside to the outside, making the extension process orderly and controllable, allowing the user to flexibly adjust the fixed height of the lamp head 300, and the tube-pulling pin 334 cooperates with the limit hole 331a to prevent the telescopic rod 300 from accidentally retracting after extension, making the use process safer.

[0051] In the above embodiment, after transporting the luggage-type lighting 10 to the destination, the sliding bracket 420 and the balancing arm 430 need to be operated to extend the sliding bracket 420, and the deployment mechanism 400 is switched to the deployed state to secure the light box 100. As shown in FIG9 , the balancing arm 430 is flipped out from the bottom of the base 410. After being fixed, the two balancing arms 430 form a "V" shape. The components of the sliding bracket 420 that contact the ground are wheels 421. To prevent the wheels 421 from sliding due to uneven roads, the wheels 421 are fixedly connected to the sliding bracket 420. To ensure that the luggage-type lighting 10 is transported more efficiently, adjacent wheels 421 are parallel. In addition, when flipping the balancing arm 430 out from the bottom of the base 410, the light box 100 needs to be tilted to lift the balancing arm 430 off the ground before the balancing arm 430 can be rotated. It's important to note that when the balancing arm 430 is lifted off the ground, only the wheels 421 of the trunk light 10 are in contact with the ground. Since the adjacent wheels 421 are parallel, the trunk light 10 is susceptible to slipping. If the trunk light 10 is mounted on a slope, deploying the balancing arm 430 requires one operator to hold the telescopic lever 300 while another operator maneuvers the arm 430 to prevent the trunk light 10 from sliding down the slope. Even after the balancing arm 430 is deployed, the side where the wheels 421 are located remains susceptible to slipping, potentially causing the trunk light 10 to slide down the slope. To avoid safety hazards, the trunk light 10 should not be mounted on steep slopes. Therefore, improving the trunk light's anti-slip properties to ensure stable installation and illumination on sloped surfaces remains a challenge.

[0052] To solve the above problem, please refer to Figures 7 and 12. A slide rail 440 is provided at the opening of the storage channel 411. The sliding bracket 420 is slidably connected to the slide rail 440. The slide rail 440 guides the sliding bracket 420 to slide, making the sliding bracket 420 extend and retract more smoothly.

[0053] Referring to Figures 11 and 13 , the sliding bracket 420 includes a handle 610, a second button 620, two supporting rods 630, and two connecting pieces 640. Each supporting rod 630 includes a fixed section 631, a swinging section 632, and a torsion spring (not shown). The swinging section 632 is rotatably mounted on the fixed section 631. The connection between the swinging section 632 and the fixed section 631 forms a pivot point 11. The torsion spring is located at the pivot point 11. The torsion spring provides an elastic force to drive the swinging section 632 to rotate relative to the fixed section 631, thereby driving the swinging sections 632 on the two supporting rods 630 away from each other. Preferably, the slide rail 440 is provided with a positioning screw 441 (as shown in Figure 7 ), and the fixed section 631 is provided with a spherical groove (not shown) that matches the positioning screw 441. The positioning screw 441 is fitted with the outer wall of the bearing rod 630 . After the sliding bracket 420 is pulled out of the receiving channel, the positioning screw 441 is embedded in the spherical groove, thereby positioning the sliding bracket 420 .

[0054] Please refer to Figure 13. The second button 620 is located inside the handle 610, and a stop buckle 621 is provided on the second button 620. The connecting piece 640 passes through the handle 610, and a hook 641 is provided on one end of the connecting piece 640 located inside the handle 610. The hook 641 is used to engage with the stop buckle 621. The other end of the connecting piece 640 is rotatably connected to the swing section 632. When the hook 641 is engaged with the stop buckle 621, the connecting piece 640 is locked, and the swing section 632 is pulled by the connecting piece 640. Pressing the second button 620 can separate the stop buckle 621 from the hook 641 to release the lock on the connecting piece 640, thereby making the swing section 632 rotatable.

[0055] 7 and 13 , a return spring 650 is provided between the second button 620 and the handle 610 . After the second button 620 is released, the return spring 650 provides elastic force to reset the second button 620 , thereby ensuring that the barb 641 can re-engage with the stop buckle 621 after the connecting piece 640 is reset.

[0056] By further optimizing the structure of the sliding bracket 420, the anti-slip capability of the trunk lighting lamp 10 is improved, and the trunk lighting lamp 10 can be fixed on a sloped location to provide lighting. The principle is as follows:

[0057] First, drag the battery box to the target location and align the light box 100. Then, the user holds the light box 100 with one hand and, with the other hand, grasps the handle 610 and pulls the sliding bracket 420 out of the storage channel 411 until the positioning screw 441 is engaged with the spherical groove and the rotation fulcrum 11 is exposed outside the slide rail 440.

[0058] Next, the second button 620 is pressed to separate the hook 641 from the locking buckle 621. At this time, the swinging section 632 rotates under the action of the torsion spring, and the two swinging sections 632 move away from each other until the locking buckle 621 abuts against the inner cavity of the handle 610. At this time, the two swinging sections 632 open to form an inverted "V" shape (as shown in FIG. 10). In this state, the two wheels 421 are no longer parallel to each other.

[0059] When the light box 100 is tilted and the balancing swing arm 430 is moved, the two wheels 421 are no longer parallel to each other, which can prevent the wheels 421 from rolling. There is no need for additional staff to support the suitcase-type lighting 10. In addition, since both the swing section 632 and the balancing swing arm 430 can be unfolded, a support point is formed at a position away from the center of the light box 100, which can further improve the anti-tilting ability of the suitcase-type lighting 10.

[0060] After use, hold the two swing sections 632 with both hands respectively, apply force to move the two swing sections 632 closer to each other, so that the connecting piece 640 is reinserted into the handle 610, and the hook 641 hooks the stop buckle 621 again to lock the swing section 632, then push the handle 610 and reinsert the sliding bracket 420 into the storage channel 411.

[0061] It should be emphasized that the swinging section 632 can only rotate when the pivot point 11 is exposed outside the slide rail 440. If the pivot point 11 is still within the slide rail 440, the slide rail 440 will contact both the swinging section 632 and the fixed section 631. Even if the second button 620 is pressed, the swinging section 632 will be blocked by the slide rail 440 and unable to rotate. This prevents the swinging section 632 from deploying within the storage channel 411 due to operator error. Furthermore, to ensure smoother extraction of the entire sliding bracket 420 from the slide rail 440, the two wheels 421 must be parallel to each other without yaw. This ensures that the two wheels 421 in contact with the ground can slide smoothly and unimpeded. Only at the end of their travel will the swinging section 632, under the action of the torsion spring, rotate relative to the fixed section 631, forming a V-shape. This is also a factor that needs to be considered during product design, rather than simply attaching the torsion spring to the wheel 421.

[0062] If the slide rail 440 is removed and the operator accidentally touches the second button 620, the swing section 632 will unfold in the storage channel 411, and the elastic force of the torsion spring will make the swing section 632 tightly attached to the inner wall of the storage channel 411. In this state, dragging the sliding bracket 420 out requires overcoming the friction between the swing section 632 and the inner wall of the storage channel 411, and it is easy to cause wear of the swing section 632 and the storage channel 411, which is laborious and easy to damage the sliding bracket 420 and its surrounding components.

[0063] The above-described embodiments merely illustrate several implementations of the present invention, and while their descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent. It should be noted that a person skilled in the art would be able to make numerous variations and improvements without departing from the spirit of the present invention, all of which fall within the scope of protection of the present invention. Therefore, the scope of protection of the patent for this invention shall be determined by the appended claims. Industrial Applicability

[0064] 1. The light box 100 is equipped with an unfolding mechanism 400. After the luggage compartment light 10 is moved to its destination, the sliding bracket 420 and the balancing arm 430 can be unfolded to form a support point away from the center of the light box 100, thereby improving the luggage compartment light 10's anti-tilting ability. Furthermore, when the sliding bracket 420 and the balancing arm 430 are retracted (as shown in FIG. 8 ), the overall size of the luggage compartment light 10 becomes smaller, allowing it to fit into narrow passages and facilitate transportation.

[0065] 2. The support rod 630 on the sliding bracket 420 is designed in sections. The swinging section 632 can swing around the fixed section 631 under the drive of the torsion spring. When the sliding bracket 420 is extended, the two swinging sections 632 form an inverted "V" shape, so that the two wheels 421 are not parallel to each other, making them less likely to slide. This allows the trunk light 10 to be fixed on a steep slope, improving the adaptability of the trunk light 10 to complex environments.

[0066] 3. The slide rail 440 cooperates with the sliding bracket 420 , which not only makes the sliding bracket 420 slide more smoothly and labor-saving, but also limits the swing of the swing section 632 to prevent the sliding bracket 420 from expanding in the storage channel 411 .
