Description

Technical Field

[0001] This utility model relates to the technical field of lighting tools, and in particular to a detachable dual-purpose work lamp. Background Technology

[0002] With the increasing demand for high-efficiency lighting equipment in fields such as outdoor operations, workshop maintenance, construction of electrical and communication wells, and emergency repairs, work lights, as key lighting tools, are receiving more and more attention from users. Currently, work lights on the market generally include floodlights and spotlights to meet different lighting needs.

[0003] Floodlights typically have a large luminous area, providing uniform diffused light for wide-area illumination at close range; spotlights, on the other hand, use spotlight bulbs or reflectors to emit high-intensity, directional, focused light for targeted illumination of specific areas at long distances. While combining floodlights and spotlights improves the practicality of work lights, current technologies often employ a fixed, integrated structure, making the floodlighting and spotlighting functions inseparable and lacking flexibility in use.

[0004] Especially in complex and confined working environments such as low-voltage electrical wells and pipeline maintenance areas, workers often need to maintain overall ambient brightness (floodlighting) while simultaneously providing focused lighting for specific lines or equipment. Existing work lights often fail to meet the need for "multi-purpose and portable lighting," resulting in inconvenience, limited lighting effects, and reduced efficiency and convenience of on-site operations.

[0005] In addition, the energy management of current multi-functional work lights is also inadequate: the battery capacity and the power of the light assembly are difficult to match, resulting in limited battery life or excessive size, which affects portability.

[0006] Based on the aforementioned technical deficiencies, there is an urgent need for a work light device with a reasonable structure, easy portability, and the ability to freely switch and combine floodlight and spotlight functions. This device should be able to ensure large-area floodlight illumination, allow for independent disassembly and flexible use of spotlights, and possess efficient battery management and a stable electrical connection solution to meet the lighting needs under diverse and complex working conditions.

The tail cover spring pin is fixed to the tail cover circuit board and forms a conductive protrusion at the bottom inner part of the second tail cover, thereby forming an electrical connection with the second battery.

[0016] Furthermore: the inner wall of the end of the second tail cover connected to the second housing is provided with a tail cover guide groove, which is L-shaped to form an insertion notch and a rotation track; the outer wall of the end of the second housing connected to the second tail cover is provided with a housing protrusion, which cooperates with the tail cover guide groove to form a detachable snap-lock connection.

[0017] Furthermore: the end of the second tail cover facing the adapter is provided with a ring-shaped locking tongue, and a push-lock is installed on the side wall of the adapter. The locking rod of the push-lock extends into the adapter, thereby locking or releasing the ring-shaped locking tongue.

[0018] Furthermore, the first component is also provided with a first spring pin, one end of which is fixed to the first circuit board and forms an electrical connection; the other end of the second spring pin abuts against the first battery and forms an electrical connection.

[0024] 2. Modular design for easy portability and operation – The second component can be detached from the first component, improving the portability and flexibility of the spotlight, allowing users to provide targeted lighting for specific areas and optimize work efficiency.

[0025] 3.

Detailed Implementation

[0042] The technical solutions in the embodiments of this utility model will be clearly and completely described below. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0043] Please see Figures 1 to 9 In this embodiment of the utility model, a detachable dual-purpose work lamp includes:

[0044] The first component 10 has a first battery 13 and a first circuit board 14 that are electrically connected to each other installed inside, and a first lamp group 11 is installed on the side wall. The first lamp group 11 is electrically connected to the first circuit board 14 and is configured to emit diffused light.

[0045] The second component 30 is inserted through the first component 10 and internally houses a second battery 33 and a second circuit board 34 electrically connected to each other. A second lamp assembly 31 is mounted at one end of the second component 30 and is electrically connected to the second circuit board 34, configured to emit focused light.

[0046] The adapter 50 is installed inside the first component 10, so that the second component 30 can be detachably and fixedly connected to the first component 10 through the adapter 50.

[0047] One end of the adapter 50 is electrically connected to the first circuit board 14, and the other end is detachably electrically connected to the second component 30.

[0048] Specifically, work lights are lighting devices designed for various working environments, playing a crucial role, especially in outdoor settings, workshops, and electrical shafts, providing users with clear and bright illumination. In actual work and usage scenarios, both diffused light for large-area floodlighting at close range and focused light for targeted illumination of key areas at a slightly farther distance are typically required. Therefore, most work lights usually have both floodlights and spotlights.

[0049] However, existing work lights, including floodlights and spotlights, lack the ability to be separated or split, preventing the simultaneous maintenance of the floodlight area and the ability to freely spotlight specific areas. This is inconvenient for practical applications. For example, in an unlit electrical shaft, workers might want to maintain a certain level of floodlight brightness across the entire area while simultaneously providing spotlight illumination for specific lines or equipment in particular locations to easily locate the lines or equipment requiring maintenance or installation.

[0050] This invention provides a first light group 11 in the first component 10 to emit diffused light, maintaining a large area of ​​floodlight illumination. At the same time, the second component 30 can be removed from the first component 10 for greater freedom of movement. The focused light emitted by the second component 30 can then be used to illuminate a specific area, assisting users in performing targeted lighting operations in that area. This facilitates more detailed on-site work and improves work efficiency.

[0051] Secondly, to create floodlighting, the first light group 11 preferably uses existing products such as light strips and light panels with a large luminous area and no focusing, as described in the prior art; while to create focused lighting, the second light group 31 preferably uses existing products such as focused LED beads and focused cups, as described in the prior art. Compared with the prior art, this utility model achieves independent control of floodlighting and focused lighting through a detachable structure, which, according to actual measurements, can reduce ineffective lighting energy consumption by 30%. At the same time, the second component 30 is 60% lighter when used alone, making it more suitable for precision work scenarios.

[0052] like Figure 4 and Figure 5 As shown, preferably, an adapter spring pin 51 is installed at the bottom of the adapter 50. One end of the adapter spring pin 51 passes through the bottom of the adapter 50 and forms an electrical connection with the first circuit board 14. The other end of the adapter spring pin 51 abuts against the end of the second component 30 that passes through the first component 10 and forms a separable electrical connection with the second component 30.

[0053] Specifically, since the first component 10 is relatively large in size and has a first battery 13 with a large capacity, while the second component 30, which is pluggably disposed in the cavity of the first component 10, is relatively small in size and has a second battery 33 with a relatively small capacity, the second battery 33 can be charged by the first battery 13 when the second component 30 is inserted into the first component 10. In order to facilitate the realization of a separable electrical connection, it is preferable to provide an adapter spring pin 51 at the bottom of the adapter 50, so that when the second component 30 passes through the inside of the first component 10, it can abut against the adapter spring pin 51, so that the charging management chip (not shown in the figure) provided on the first circuit board 14 can charge the first battery 13.

[0054] Secondly, the charging management chip can charge the second battery 33 using the power from the first battery 13, or it can charge the second battery 33 using external power connected to the charging interface 16 of the first component 10. Furthermore, the charging management chip can also charge the first battery 13 using external power connected to the charging interface 16. The charging interface 16 can be a USB Type-C interface as used in the prior art, and the charging management chip can be a power management chip as used in the prior art.

[0055] Furthermore, all the spring pins in this invention can adopt the existing Pogo pin connector. A Pogo pin is a spring-type probe formed by riveting and pre-compressing three basic components: a pin shaft, a spring, and a pin tube, using precision instruments. It contains a precision spring structure. The Chinese name is spring pin, and it is widely used in various electronic products, mainly for current and signal transmission, i.e., charging and conductivity.

[0056] like Figures 6 to 9 As shown, preferably, the second component 30 is provided with a second housing 36 and a second tail cap 40. The second battery 33 and the second circuit board 34 are respectively installed in the internal space of the second housing 36. The second lamp group 31 and the second tail cap 40 are respectively fastened to both ends of the second housing 36. The inner side of the second tail cap 40 abuts against the second battery 33 to form an electrical connection, and its outer side is detachably abuts against the adapter spring pin 51.

[0057] Specifically, the second housing 36 can adopt a cylindrical structure, so that the second battery 33 passes through the internal space of the cylindrical structure. One end of the cylindrical structure is used to install the second lamp group 31 and the second circuit board 34, and the other end can be provided with a second tail cap 40. After the second battery 33 is installed, the second tail cap 40 is fastened to the opening of the cylindrical structure. Sealing rings can be provided between the second tail cap 40 and the second housing 36, as well as between the second lamp group 31 and the second housing 36, so that the second component 30 achieves a waterproof effect and enhances its adaptability when carried and used.

[0058] Secondly, a second switch 35 can be provided on the second circuit board 34, so that the second switch 35 is electrically connected to the second circuit board 34 and configured to switch the second lamp group 31 on and off. A second button 37 can also be provided on the side wall of the second component 30. The second button 37 can be a waterproof button and configured to press the second switch 35.

[0059] Furthermore, a second spring pin 32 can be installed on the second circuit board 34, so that one end of the second spring pin 32 is fixed to the second circuit board 34 and forms an electrical connection, and the other end abuts against the second battery 33 to form an electrical connection.

[0060] like Figure 6 As shown, preferably, the second tail cover 40 is further provided with a tail cover circuit board 41, a tail cover conductive sheet 42, and a tail cover spring pin 43. The tail cover conductive sheet 42 is installed at the end of the second tail cover 40 facing the adapter spring pin 51 and extends into the interior of the second tail cover 40 to form an electrode tab, thereby forming an electrical connection with the tail cover circuit board 41. The tail cover spring pin 43 is fixed to the tail cover circuit board 41 and forms a conductive protrusion at the inner bottom of the second tail cover 40, thereby forming an electrical connection with the second battery 33.

[0061] Specifically, in order for the adapter spring pin 51 to electrically connect to the second battery 33 inside the second component 30, it is preferable to provide a corresponding conductive line on the second tail cap 40 to serve as a transition. That is, annularly distributed tail cap conductive plates 42 are provided at the tail end of the second tail cap 40, so that when the second component 30 is inserted into the first component 10 at any angle in the circumferential direction, its annularly distributed tail cap conductive plates 42 can form an electrical connection with the adapter spring pin 51.

[0062] Secondly, a tail cover circuit board 41 and a tail cover spring pin 43 can be provided at the inner bottom of the second tail cover 40, so that the tabs of the tail cover conductive sheet 42 pass through the second tail cover 40 and are electrically connected to the tail cover circuit board 41, while the tail cover spring pin 43 can be directly fixed to the tail cover circuit board 41, and its conductive pin shaft protrudes from the inner bottom of the second tail cover 40, so that when the second tail cover 40 is fastened to the second housing 36, the tail cover spring pin 43 is electrically connected to the second battery 33.

[0063] Furthermore, to facilitate replacement and connection, conductive portions, as used in the prior art, can be provided at both ends of the second battery 33, allowing its ends to be electrically connected to the second circuit board 34 and the tail cover circuit board 41, respectively. For example, a circular positive conductive electrode can be provided in the middle of the conductive portion, and an annular negative conductive electrode can be provided at a certain distance from the outer edge of the positive conductive electrode. An insulating structure can be provided between the positive and negative conductive electrodes, so that the positive conductive electrode is electrically connected to the positive electrode of the battery, and the negative conductive electrode is electrically connected to the negative electrode of the battery.

[0064] like Figures 7 to 9As shown, preferably, the inner wall of the end of the second tail cap 40 connected to the second housing 36 is provided with a tail cap guide groove 44, which is L-shaped to form an insertion notch 45 and a rotation track 46; the outer wall of the end of the second housing 36 connected to the second tail cap 40 is provided with a housing protrusion 38, so that the housing protrusion 38 and the tail cap guide groove 44 cooperate with each other to form a detachable snap-lock connection.

[0065] Specifically, in order to replace the second battery 33, it is preferable to set the second tail cover 40 as a detachable snap-fit ​​connection. Therefore, the housing protrusion 38 provided on the second housing 36 can be used to insert it axially through the insertion notch 45, so that the housing protrusion 38 enters the rotating track 46. Then, it is rotated at a certain angle so that the housing protrusion 38 is stuck by the side wall of the rotating track 46 to prevent it from axially dislodging and to achieve mechanical interlocking.

[0066] Secondly, in order to further enhance the locking strength, a semi-circular groove can be provided on the housing protrusion 38, and a semi-circular protrusion can be provided on the rotating track 46 at the position corresponding to the semi-circular groove. The semi-circular protrusion is used to engage with the semi-circular groove to form an enhanced lock, ensuring that the second tail cover 40 will not fall off accidentally during use.

[0067] like Figure 4 , Figure 5 , Figure 6 , Figure 8 and Figure 9 As shown, preferably, the second tail cover 40 has an annular locking tongue 47 at the end facing the adapter 50, and a press lock 52 is installed on the side wall of the adapter 50. The locking rod 53 of the press lock 52 extends into the adapter 50, thereby locking or releasing the annular locking tongue 47.

[0068] Specifically, to prevent the second component 30 from accidentally coming out after being inserted into the first component 10, a press-lock 52, as in the prior art, can be provided in the adapter 50, and an annular locking tongue 47 can be provided on the outer side wall of the end of the second tail cover 40, so that when the second component 30 is inserted into the first component 10, the second tail cover 40 is inserted into the adapter 50, and the annular locking tongue 47 presses the locking rod 53 of the press-lock 52, so that the locking rod 53 forms a locked or unlocked state with the annular locking tongue 47.

[0069] Secondly, the snap-on latch 52, also called the door latch switch, is a latch with self-locking and spring-opening functions in existing technology. Due to its simple and convenient installation, it is often used on some lightweight door covers. Since the ring-shaped latch 47 has a latch portion in the circumferential direction, the snap-on latch 52 can adopt the existing snap-on latch 52 with a one-way locking lever 53. When unlocking, the locking lever 53 deflects a certain angle away from the ring-shaped latch 47, thereby unlocking the ring-shaped latch 47. If pressed again, it returns to the initial state, realizing the locking control of the ring-shaped latch 47.

[0070] like Figure 4 and Figure 5 As shown, preferably, the first component 10 is further provided with a first spring pin 12, one end of the first spring pin 12 is fixed to the first circuit board 14 and forms an electrical connection; the other end of the second spring pin 32 abuts against the first battery 13 and forms an electrical connection.

[0071] Specifically, to facilitate the replacement of the first battery 13, a first spring pin 12 can be provided on the first circuit board 14. The first spring pin 12 is used to abut against the conductive part of the first battery 13, thereby forming a detachable electrical connection. The conductive parts of the first battery 13 and the second battery 33 are the same, and can be set using conductive discs or conductive rings in the prior art, so that the positive and negative contacts of the battery are distributed at the end of the battery, thereby facilitating the abutment of the spring pin and forming a stable electrical connection.

[0072] like Figure 1 and Figure 3 As shown, preferably, the first component 10 is further provided with a first tail cover 21, and the first component 10 has a first cavity for installing the first battery 13 inside, and the first tail cover 21 is fastened to the opening of the first cavity.

[0073] Specifically, in order to replace the first battery 13, a first tail cap 21 can be provided at the opening of the first cavity inside the first component 10. The first tail cap 21 is used to seal the first cavity, and at the same time, the first tail cap 21 also abuts against the first battery 13, so that the first battery 13 and the first spring pin 12 are in a tight fit, thereby forming a stable electrical connection.

[0074] Secondly, to facilitate opening and locking of the first tail cover 21, a protrusion structure similar to the housing protrusion 38 can be provided on the first tail cover 21, and a guide groove structure similar to the tail cover guide groove 44 can be provided at the corresponding part of the first component 10, so that a detachable fastening connection is formed between the first tail cover 21 and the first component 10. Similarly, corresponding semi-circular protrusions and semi-circular grooves can also be provided to enhance the locking of the first tail cover 21.

[0075] like Figures 2 to 5As shown, preferably, the first component 10 is further provided with a first housing 20 and a first cover 22. One end of the first housing 20 is provided with a first cylinder and a first cavity. The first cylinder is used to detachably install the second component 30, and the first cavity is used to detachably install the first battery 13. The first circuit board 14 is installed in the first opening at the other end of the first housing 20, and the first cover 22 is used to close the first opening.

[0076] Specifically, for ease of installation, a first cylinder and a first cavity are preferably provided at one end of the first housing 20, so that the second component 30 can be detachably installed in the first cylinder and the first battery 13 can be detachably installed in the first cavity. At the other end of the first housing 20, a first opening is provided to facilitate the installation of the first circuit board 14, and a first cover 22 is provided to close the first opening, thereby protecting the first circuit board 14 and forming the first component 10 into a complete working light device.

[0077] like Figure 2 and Figure 3 As shown, preferably, the first circuit board 14 is further provided with a first switch 15, so that the first switch 15 is electrically connected to the first circuit board 14 and is configured to perform a switching operation on the first lamp group 11; the first cover 22 is further provided with a first button 23, which is configured to press the first switch 15.

[0078] Specifically, one end of the first button 23 is also provided with a dust plug 24, which is used to cover the charging interface 16, thereby protecting the charging interface 16. To allow independent control of the first light group 11, a first switch 15 is preferably provided to control the on / off state of the first light group 11 independently. Similarly, the first button 23 can be designed as a waterproof button to enhance the overall waterproof performance of the work light. In addition, an indicator light 17 is provided on the first circuit board 14, which indicates the current status of the work light and the power level of the first battery 13 or the second battery 33, facilitating better user operation.

[0079] Additionally, it should be noted that in this invention, all the spring pins that achieve electrical connection are configured in two sets, which are respectively electrically connected to the positive and negative terminals of the corresponding battery or circuit.

[0080] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.
