Description

Technical Field

[0001] This invention relates to the field of lighting technology, and more particularly to a portable lighting device. Background Technology

[0002] In addition to indoor use, handheld lighting devices are also widely used in outdoor adventures, camping, and emergency rescue due to their portability.

[0003] Normally, a single lighting device can be shared by a group of travelers. However, when some members of the group need to separate from others, both groups require lighting, which a single, ordinary lighting device cannot meet. Carrying more than two lighting devices to meet the requirements is costly, inconvenient, and requires carrying them separately, resulting in a large overall space consumption and poor consistency. Summary of the Invention

[0004] In view of the above-mentioned shortcomings of the existing technology, the technical problem to be solved by the present invention is to provide a portable lighting device with a wide range of applications and good overall consistency.

[0005] The technical solution adopted by this invention to solve its technical problem is to propose a portable lighting device, comprising:

[0006] A first lighting unit and a second lighting unit, wherein the second lighting unit may be installed on the first lighting unit and may be removed from the first lighting unit, and both the first lighting unit and the second lighting unit may be configured as lighting tools independently;

[0007] When the second lighting unit is installed on the first lighting unit:

[0008] The second lighting unit is completely housed within the first lighting unit;

[0009] Alternatively, the housing of the second lighting unit is adjacent to the housing of the first lighting unit;

[0010] Alternatively, the outer casing wall of the first lighting unit may be at least partially formed by the outer casing wall of the second lighting unit.

[0011] Furthermore, the first lighting unit is provided with a buckle, and when the second lighting unit is installed on the first lighting unit, the buckle is engaged with the second lighting unit.

[0012] Furthermore, the first lighting unit is symmetrically provided with two buckles, and the second lighting unit is provided with two buckle slots on both sides. When the second lighting unit is installed on the first lighting unit, the two buckles are respectively engaged in the two buckle slots.

[0013] Furthermore, the first lighting unit is provided with a mounting compartment, and the mounting compartment forms an opening communicating with the outer wall of the first lighting unit;

[0014] The second lighting unit can be installed in the mounting compartment along the opening, and can be removed from the mounting compartment along the opening.

[0015] Furthermore, the opening is provided at the tail end of the first lighting unit away from its lamp head;

[0016] The mounting chamber is equipped with a spring return mechanism, which has a retracted state and an extended state. When the second lighting unit is installed in the mounting chamber along the opening, the second lighting unit can switch the spring return mechanism to the retracted state. When the second lighting unit is pushed inward, the spring return mechanism can switch the spring return mechanism to the extended state, and the spring return mechanism pushes the second lighting unit out along the opening.

[0017] Furthermore, the first lighting unit is provided with a socket, which is electrically connected to the battery of the first lighting unit;

[0018] When the second lighting unit is installed on the first lighting unit, the second lighting unit is plugged into the socket, the buckle is secured to the second lighting unit, and the first lighting unit can charge the second lighting unit.

[0019] Furthermore, the first lighting unit has a mounting base in its housing, the socket is slidably disposed on the mounting base, and the buckle is disposed on the socket;

[0020] When the second lighting unit is installed on the first lighting unit, the second lighting unit pushes the socket inward to slide along the mounting base; when the socket slides in the opposite direction along the mounting base, the socket pushes the second lighting unit to move away from the first lighting unit.

[0021] Furthermore, the mounting base is provided with several partitions, and the partitions and the mounting base form a first compartment and a second compartment. The control module and battery of the first lighting unit are disposed in the first compartment. When the second lighting unit is disposed in the first lighting unit, the second lighting unit is located in the second compartment.

[0022] Furthermore, the first lighting unit is provided with a rotatable cover along the opening. When the second lighting unit is installed into the mounting compartment, the second lighting unit pushes inward and limits the cover. When the second lighting unit is removed from the mounting compartment, the cover restores its position to cover the opening.

[0023] Furthermore, when the second lighting unit is installed in the mounting compartment, the second lighting unit is completely contained within the mounting compartment, or the end of the second lighting unit near the opening is flush with the tail end face of the first lighting unit.

[0024] Compared with the prior art, the present invention has at least the following beneficial effects:

[0025] In this invention, the second lighting unit can be freely installed and detached from the first lighting unit, and both the first and second lighting units can be configured independently as lighting tools. When using this lighting device outdoors, if some people need to separate from others, carrying just one of these lighting devices is sufficient to meet the usage requirements, thus having a wide range of applications. When the second lighting unit is installed in the first lighting unit, the second lighting unit is completely contained within the first lighting unit, or the second lighting unit is adjacent to the first lighting unit, or the second lighting unit fills part of the outer shell wall of the first lighting unit, ensuring the overall consistency of the lighting device's appearance and high aesthetic appeal.

[0036] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0037] It should be noted that all directional indications (such as up, down, left, right, front, back, etc.) in the embodiments of the present invention are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indication will also change accordingly.

[0038] Furthermore, in this invention, descriptions involving "first," "second," etc., are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this invention, "a plurality of" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0039] In this invention, unless otherwise explicitly specified and limited, the terms "connection," "fixed," etc., should be interpreted broadly. For example, "fixed" can mean a fixed connection, a detachable connection, or an integral part; it can mean a mechanical connection or an electrical connection; it can mean a direct connection or an indirect connection through an intermediate medium; it can mean the internal communication of two components or the interaction between two components, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0040] Furthermore, the technical solutions of the various embodiments of the present invention can be combined with each other, but only if they are feasible for those skilled in the art. If the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such combination of technical solutions does not exist and is not within the scope of protection claimed by the present invention.

[0041] like Figures 1-2As shown, a portable lighting device mainly includes: a first lighting unit 1 and a second lighting unit 2. The first lighting unit 1 may be, but is not limited to, a handheld spotlight, and the second lighting unit 2 may be, but is not limited to, a portable flashlight. The second lighting unit 2 can be installed in the first lighting unit 1 and can also be removed from the first lighting unit 1. Both the first lighting unit 1 and the second lighting unit 2 can be configured as lighting tools independently, and both are portable lighting tools. During use, when the second lighting unit 2 is installed in the first lighting unit 1, it functions as a single unit, making it easy to carry and usable as a whole. When the second lighting unit 2 is removed from the first lighting unit 1, both the first lighting unit 1 and the second lighting unit 2 can be used independently as lighting units, essentially making the lighting device split into two, suitable for situations where people are separated when traveling.

[0042] To ensure the overall consistency of the lighting equipment in this embodiment, it can be achieved in various ways, such as:

[0043] When the second lighting unit 2 is installed in the first lighting unit 1: the second lighting unit 2 is completely contained in the first lighting unit 1. As the optimal way in this embodiment, after the second lighting unit 2 is completely contained in the first lighting unit 1, the second lighting unit 2 does not need to occupy any additional space. From the appearance, the shape of the lighting device is the same as the shape of the first lighting unit 1, which is aesthetically pleasing.

[0044] Alternatively, when the second lighting unit 2 is installed on the first lighting unit 1: the outer shell of the second lighting unit 2 is adjacent to the outer shell of the first lighting unit 1. In this implementation, a connecting structure, such as a mounting bracket, is provided on the first lighting unit 1 for the second lighting unit 2 to be snapped into place. When the second lighting unit 2 is installed on the first lighting unit 1, the two are arranged side by side to ensure a compact structure. The outer shells of both the first lighting unit 1 and the second lighting unit 2 can be kept intact, eliminating the need for grooves or recesses in the first lighting unit 1 for the second lighting unit 2 to be installed.

[0045] Alternatively, when the second lighting unit 2 is installed on the first lighting unit 1: the outer shell wall of the first lighting unit 1 is at least partially formed by the outer shell wall of the second lighting unit 2. In this implementation, a corresponding groove or recess needs to be provided on the outer shell of the first lighting unit 1 for the second lighting unit 2 to be installed. After the second lighting unit 2 is installed in the groove or recess on the outer shell of the first lighting unit 1, the second lighting unit 2 fills the groove or recess to ensure the overall appearance consistency of the lighting equipment.

[0046] During use, the second lighting unit 2 in this embodiment can be freely installed and removed from the first lighting unit 1, and both the first lighting unit 1 and the second lighting unit 2 can be configured as lighting tools independently. When using this lighting device outdoors, if some people need to act separately from others, carrying one of these lighting devices is sufficient to meet the usage requirements, making it widely applicable. When the second lighting unit 2 is installed in the first lighting unit 1, the second lighting unit 2 is completely contained within the first lighting unit 1, or the second lighting unit 2 is adjacent to the first lighting unit 1, or the second lighting unit 2 fills part of the outer shell wall of the first lighting unit 1, ensuring the overall consistency of the lighting device's appearance and high aesthetic appeal.

[0047] like Figures 2-4 As shown, the first lighting unit 1 is provided with a mounting compartment 11, and the mounting compartment 11 forms an opening 110 communicating with it on the outer wall of the first lighting unit 1. The second lighting unit 2 can be installed in the mounting compartment 11 along the opening 110, and can also be removed from the mounting compartment 11 along the opening 110. During use, when the second lighting unit 2 is installed in the mounting compartment 11, the second lighting unit 2 is completely contained in the mounting compartment 11, or the end of the second lighting unit 2 near the opening 110 is flush with the tail end of the first lighting unit 1, ensuring that the installation of the second lighting unit 2 does not affect the size of the first lighting unit 1 and does not occupy additional space. The first lighting unit 1 can also serve as a support for the second lighting unit 2, providing support when only the second lighting unit 2 is used. After the second lighting unit 2 is installed in the first lighting unit 1, the lamp head of the second lighting unit 2 faces opposite to the lamp head of the first lighting unit 1. At this time, the lighting device of this embodiment can emit light from the center to both sides simultaneously.

[0048] Specifically, the opening 110 is located at the tail end of the first lighting unit 1, away from its lamp head; that is, the opening 110 is located at the tail end of the first lighting unit 1. The first lighting unit 1 is provided with a handle 19, and the grip portion of the handle 19 extends from the lamp head to the tail end along the main body direction of the first lighting unit 1. The opening direction of the mounting compartment 11 is basically consistent with the main body direction of the first lighting unit 1, that is, approximately parallel to the grip portion of the handle 19, facilitating the installation and removal of the second lighting unit 2. Furthermore, this ensures that the first lighting unit 1 does not need to be very large to fully accommodate the second lighting unit 2.

[0049] Furthermore, a rotatable cover 18 is provided at the opening 110 of the first lighting unit 1. When the second lighting unit 2 is installed into the mounting chamber 11, the second lighting unit 2 is pushed inward and the cover 18 is positioned. When the second lighting unit 2 is removed from the mounting chamber 11, the cover 18 returns to its original position, blocking the opening 110. Specifically, a protruding post extends from both sides of the cover 18, and the cover is rotatably installed in the first lighting unit 1 through the protruding post. A torsion spring is provided between the cover 18 and the mounting base 14 of the first lighting unit 1. When the second lighting unit 2 is not installed into the first lighting unit 1, the spring force of the torsion spring holds the cover 18 at the opening 110, blocking the opening 110 to prevent debris from entering the mounting chamber 11 and ensuring that the internal structure of the mounting chamber 11 of the first lighting unit 1 is not visible from the outside. When the second lighting unit 2 is inserted into the mounting chamber 11 along the opening 110, the second lighting unit 2 pushes open the cover 18 inward and presses the cover 18 against the mounting base 14. The mounting base 14 is provided with a recess. The cover 18 is limited and stays in the recess by the second lighting unit 2. At this time, the torsion spring is further compressed to ensure that when the second lighting unit 2 is taken out of the mounting chamber 11, the torsion spring will drive the cover 18 to return to its initial position and keep the opening 110 blocked.

[0050] like Figure 6 As shown, in this embodiment, a mounting base 14 is provided in the outer shell of the first lighting unit 1. The mounting base 14 is provided with a plurality of partitions 17. The plurality of partitions 17 and the mounting base 14 form a first compartment 170 and a second compartment 171. Specifically, there are upper partitions and lower partitions. The mounting base 14 has an upper opening and a lower opening. The upper partition is detachably covered on the upper opening of the mounting base 14, and the lower partition is covered on the lower opening of the mounting base 14. Both the upper partition and the lower partition are detachably and fixedly connected to the mounting base 14. The control module 16 and battery 15 of the first lighting unit 1 are both located in the first compartment 170. When the second lighting unit 2 is located in the second compartment 171, the first compartment 170 and the second compartment 171 are on opposite sides. The battery 15 and the control module 16 of the first lighting unit 1 are parallel to the second lighting unit 2 installed in the second compartment 171 and also parallel to the handle 19 of the first lighting unit 1, ensuring that the lighting equipment is highly compact and facilitating the miniaturization of the lighting equipment.

[0051] Two support blocks are provided on the opposite side of the handle 19 of the first lighting unit 1. The two support planes at the bottom of the support blocks are on the same horizontal plane. In this embodiment, when the second lighting unit 2 is installed in the first lighting unit 1, the battery 15 and control module 16 of the first lighting unit 1, and the battery and control circuit board of the second lighting unit 2 are basically located between the two support blocks. Furthermore, the proximity of the second lighting unit 2 to the two support blocks can simultaneously ensure the placement stability of the lighting equipment. The extension direction of the battery of the second lighting unit 2 is perpendicular to the extension direction of the battery 15 of the first lighting unit 1.

[0052] like Figure 4 , Figure 5 and Figure 7 As shown, the first lighting unit 1 includes a socket 13, which is slidably mounted on a mounting base 14. A groove 130 is provided on each side of the socket 13, and a slide rail 140 extends from the mounting base 14 towards each of the grooves 130. The two slide rails 140 pass through the grooves 130 respectively. When the socket 13 slides back and forth relative to the mounting base 14, it slides along the slide rails 140. This guides the socket 13 while ensuring it does not detach from the mounting base 14. Furthermore, several spaced protrusions are provided on the upper and lower surfaces of the slide rails 140 to prevent large-plane contact between the socket 13 and the mounting base 14 during sliding, maintaining a line contact as much as possible and reducing the sliding friction of the socket 13.

[0053] In this embodiment, the socket 13 is electrically connected to the battery 15 of the first lighting unit 1. When the second lighting unit 2 is installed in the first lighting unit 1, the second lighting unit 2 is plugged into the socket 13, the latch 10 is secured to the second lighting unit 2, and the first lighting unit 1 can charge the second lighting unit 2. In this embodiment, when the second lighting unit 2 is installed in the mounting compartment 11, the socket 13 is plugged into the second lighting unit 2. The battery 15 in the first lighting unit 1 is electrically connected to the second lighting unit 2 through the socket 13, allowing the first lighting unit 1 to charge the second lighting unit 2, ensuring sufficient power when the second lighting unit 2 is removed for use. It is plug-and-charge, requiring no switch. During use, when the second lighting unit 2 is installed in the first lighting unit 1, the second lighting unit 2 pushes the socket 13 inwards, sliding it along the mounting base 14. When the socket 13 slides in the opposite direction along the mounting base 14, the socket 13 pushes the second lighting unit 2 away from the first lighting unit 1.

[0054] As a preferred embodiment, after the second lighting unit 2 is inserted into the mounting compartment 11 of the first lighting unit 1, the socket 13 is inserted into the second lighting unit 2, and a corresponding switch can be set to enable the battery in the second lighting unit 2 to reverse charge the first lighting unit 1, thereby improving the utilization rate of the battery in the second lighting unit 2.

[0055] In this embodiment, a snap-fit ​​10 is provided on each side of the socket 13. The snap-fit ​​10 is a resilient snap-fit. The second lighting unit 2 has two slots 20 on each side that accommodate the snap-fit ​​10. When the second lighting unit 2 is installed on the first lighting unit 1, the two snap-fit ​​10s are respectively engaged in the two slots 20. During use, when the second lighting unit 2 is inserted into the mounting compartment 11 along the opening 110, the socket 13 will align with the charging port on the second lighting unit 2. At this time, the two snap-fit ​​10s and the two slots 20 remain engaged, ensuring that the second lighting unit 2 will not accidentally detach or loosen from the socket 13 during charging, thus preventing short circuits.

[0056] A spring return device 12 is provided in the installation chamber 11, and the spring return device 12 has a retracted state and an extended state. When the second lighting unit 2 is installed in the installation chamber 11 along the opening 110, the second lighting unit 2 can switch the spring return device 12 to the retracted state; when the second lighting unit 2 is pushed inward, the spring return device 12 can switch the spring return device 12 to the extended state, and the spring return device 12 pushes the second lighting unit 2 back, pushing the second lighting unit 2 out along the opening 110.

[0057] It should be explained that the function of the spring-loaded mechanism 12 in this embodiment is as follows: when the second lighting unit 2 is inserted into the mounting compartment 11, the spring-loaded mechanism 12 is compressed to the retracted state, at which time the second lighting unit 2 is completely contained in the mounting compartment 11; when it is necessary to remove the second lighting unit 2, the second lighting unit 2 is pushed inward, and the second lighting unit 2 drives the spring-loaded mechanism 12 to switch to the extended state. Therefore, the spring-loaded mechanism 12 will cause the second lighting unit 2 to be pushed out from the opening 110 along the mounting compartment 11, making it convenient for the user to remove the second lighting unit 2. The spring-loaded mechanism 12 in this embodiment can be, but is not limited to, a cabinet door-like spring-loaded mechanism 12, including a main body, a telescopic rod, and a spring. The spring is disposed between the main body and the telescopic rod. The main body is fixedly installed in the first lighting unit 1. When the second lighting unit 2 presses against the telescopic rod, the spring-loaded mechanism 12 is in the retracted state. When the second lighting unit 2 presses against the telescopic rod again, the spring-loaded mechanism 12 is in the extended state. That is, one press closes and one press opens, making it convenient to take out and put in the second lighting unit 2.

[0058] The working principle of this portable lighting device is as follows:

[0059] When only one lighting tool is needed, the second lighting unit 2 is pushed into the mounting chamber 11 along the opening 110 at the tail end of the first lighting unit 1. The second lighting unit 2 is connected to the socket 13, and the two clips 10 on the socket 13 are engaged in the two slots 20 of the second lighting unit 2. The second lighting unit 2 continues to move inward, pushing the socket 13 inward to push the spring mechanism 12, so that the spring mechanism 12 switches to the retracted state, that is, the second lighting unit 2 is completely housed in the first lighting unit 1, and the whole unit becomes a lighting tool.

[0060] When two lighting tools are needed, press the second lighting unit 2 inward, causing the second lighting unit 2 and the socket 13 to push the spring mechanism 12 inward, causing the spring mechanism 12 to switch to the extended state. The spring mechanism 12 pushes the socket 13 and the second lighting unit 2 outward together, and the second lighting unit 2 protrudes from the opening 110 at the tail end of the first lighting unit 1. The user can then remove the second lighting unit 2. The mounting base 14 limits the socket 13, and the slot 20 disengages from the buckle 10, thus realizing the division of the lighting equipment into two, and the two lighting tools can be used independently.

[0061] In this solution, the second lighting unit 2 of the lighting equipment can be removed from the first lighting unit 1, and both the first lighting unit 1 and the second lighting unit 2 can be configured as lighting tools independently. The lighting equipment has good overall consistency and a wide range of applications.
