Description

Technical Field

[0001] This utility model relates to the field of electric drill lighting technology, and in particular to a near-infrared lighting device for silent electric drills. Background Technology

[0002] Silent electric drills are primarily used for detecting movement from targets behind walls. They allow for silent drilling into various wall materials, including brick and concrete walls, concrete, aluminum-lithium alloy plates, iron plates, glass curtain walls, and ceramic curtain walls. Due to their specialized function and the specific working environment, they feature high drilling speed, high torque, low noise, small size, light weight, reversible rotation, adjustable speed, versatility in drilling various media, ease of operation, and portability. To adapt to nighttime working environments, silent electric drills typically employ a front-mounted LED light for illumination, ensuring normal operation.

[0003] In existing technologies, concealment is one of the core technologies of silent electric drills. This is mainly achieved by reducing noise and other sources of exposure risk in the usage environment. The light source during the use of a silent electric drill is also a significant exposure risk. Currently, focused LED lights are mainly used to control the light at a certain angle, but this still poses a certain risk, thereby increasing the chances of the user being discovered during use and reducing the applicability of the equipment. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a near-infrared lighting device for silent electric drills.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a near-infrared lighting device for a silent electric drill, comprising a silent motor body, an LED spotlight fixed on the front of the silent motor body, an infrared lighting lamp fixed on the front of the silent motor body, the infrared lighting lamp being located below the LED spotlight, a control button being provided on one side of the silent motor body, and a control circuit being provided on the inner wall of the silent motor body, the control button being electrically connected to the LED spotlight and the infrared lighting lamp through the control circuit.

[0006] Preferably, the front of the silent motor body has multiple mounting slots, the inner wall of the mounting slots has multiple limiting strips fixed, one end of the inner wall of the mounting slots has a contact groove, the inner wall of the mounting slots is slidably connected to a module light component, the surface of the module light component has limiting grooves at the corresponding positions of the limiting strips, and the back of the module light component has multiple contact points fixed.

[0007] Preferably, the end of the limiting strip near the module lamp is provided with a protective arc surface.

[0008] Preferably, a rubber layer is glued to one end of the inner wall of the limiting groove.

[0009] Preferably, the module lamp has a movable groove on its front side, a shaft is fixed to the inner wall of the movable groove, a movable piece is rotatably connected to the surface of the shaft, and an infrared lighting lamp is fixed to the front side of the movable piece.

[0011] Preferably, a plurality of blocking components are fixed to the inner wall of the silent motor body at the end away from the card.

[0012] Preferably, a rubber head is fixed to one end of the blocking component.

[0013] Beneficial effects:

[0014] 1. This utility model adds a 940nm near-infrared lamp to the existing LED lighting. It allows switching between LED and near-infrared lamps depending on the usage environment. LED lamps are used for general lighting, while near-infrared lamps are used for special environments when paired with infrared night vision glasses. Due to the characteristics of 940nm near-infrared lamps, this wavelength of light cannot be directly observed by the naked eye. It mainly illuminates the surface of the irradiated object by emitting near-infrared light, causing it to reflect more light under the action of near-infrared light, thereby improving the brightness and clarity of the near-infrared image. This effectively reduces the exposure risk when using a silent electric drill in the dark.

[0015] 2. This utility model realizes the modularization of LED spotlights and infrared lighting lamps through modular lighting components. Once one of them is damaged, the staff can quickly replace it and easily disassemble and assemble it, thereby realizing battery replacement. The combination of the limiting groove and the limiting strip can ensure the position of the modular lighting components when the silent motor body vibrates during production, preventing it from swaying left and right, thereby improving the user experience.

[0016] 3. This utility model achieves the fixation of the module light component to the inner wall of the mounting groove by the cooperation of the fixing groove and the clip, preventing the module light component from detaching from the silent motor body. At the same time, the cooperation of the two restricts the module light component from swaying up and down in the mounting groove, thereby improving the user experience. Attached Figure Description

[0034] To make the technical means, creative features, and achieved objectives and effects of this utility model easier to understand, the present utility model is further described below with reference to specific embodiments and accompanying drawings. However, the following embodiments are merely preferred embodiments of this utility model and not all of them. Other embodiments obtained by those skilled in the art based on the embodiments described in the implementation plan without creative effort are all within the protection scope of this utility model.

[0035] The specific embodiments of this utility model are described below with reference to the accompanying drawings. Specific Implementation Example 1:

[0037] Reference Figures 1-7A near-infrared lighting device for a silent electric drill includes a silent motor body 1, an LED spotlight 2 fixed to the front of the silent motor body 1, and an infrared lamp 201 fixed to the front of the silent motor body 1, located below the LED spotlight 2. A control button 202 is provided on one side of the silent motor body 1, and a control circuit is provided on the inner wall of the silent motor body 1. The control button 202 is electrically connected to the LED spotlight 2 and the infrared lamp 201 through the control circuit. In addition to the original LED lighting, a 940nm near-infrared lamp 201 is added, which can be adjusted according to the usage environment. The system allows for switching between LED lights and near-infrared illuminators 201. LED lights are used for illumination in normal environments, while near-infrared illuminators 201 are used in special environments when paired with infrared night vision goggles. Due to the characteristics of the 940nm near-infrared illuminator 201, this wavelength of light is not directly observable to the naked eye. It primarily illuminates the surface of the irradiated object by emitting near-infrared light, causing it to reflect more light and thus improving the brightness and clarity of the near-infrared image. This effectively reduces the exposure risk when using a silent drill in darkness.

[0038] The main body 1 of the silent motor has multiple mounting slots 302 on its front side. Multiple limiting strips 303 are fixed to the inner wall of the mounting slots 302. One end of the inner wall of the mounting slot 302 is provided with a contact groove 305. A modular light component 3 is slidably connected to the inner wall of the mounting slot 302. A limiting groove 301 is provided on the surface of the modular light component 3 at the corresponding position of the limiting strip 303. Multiple contacts 304 are fixed on the back of the modular light component 3. The modular light component 3 makes the LED spotlight 2 and the infrared lighting 201 modular. If one of them is damaged, the staff can quickly replace it and easily disassemble and assemble it to replace the battery. When the main body 1 of the silent motor vibrates during production, the modular light component 3 can keep its position and prevent it from swaying left and right.

[0039] The end of the limiting strip 303 near the module lamp 3 is provided with a protective arc surface 4. The protective arc surface 4 can prevent the limiting strip 303 from being squeezed in the limiting groove 301 and the sharp edge from causing damage to the module lamp 3 when the operator presses the module lamp 3 into the mounting groove 302.

[0040] A rubber layer 5 is glued to one end of the inner wall of the limiting groove 301. The rubber layer 5 provides a buffer between the limiting groove 301 and the limiting strip 303 to prevent damage to both and improve the service life of the equipment.

[0041] The module lamp 3 has a movable groove 6 on its front side. A shaft 601 is fixed to the inner wall of the movable groove 6. A movable piece 602 is rotatably connected to the surface of the shaft 601. An infrared lamp 201 is fixed to the front of the movable piece 602. The shaft 601 allows the movable piece 602 to finely adjust its angle in the movable groove 6, thereby enabling relative rotation between the infrared lamp 201 and the module lamp 3. This allows the infrared lamp 201 to change its orientation and increases its applicable range.

[0042] The modular light component 3 has fixing slots 7 on both sides. A clip 701 is slidably connected to the inner wall of the mounting slot 302 of the silent motor body 1. One end of the clip 701 has an auxiliary arc surface 706, and the other end of the clip 701 is fixed with a connecting rod 702. One end of the connecting rod 702 is fixed with a finite circle component 704, and a return spring 703 is provided on the circumference of the connecting rod 702. An electromagnet 705 is fixed to the inner wall of the silent motor body 1. Through the cooperation of the fixing slots 7 and the clips 701, the modular light component 3 is fixed to the inner wall of the mounting slot 302 to prevent the modular light component 3 from separating from the silent motor body 1. At the same time, the cooperation of the two restricts the modular light component 3 from shaking up and down in the mounting slot 302, thereby improving its stability.

[0043] Multiple blocking elements 9 are fixed to the inner wall of the silent motor body 1 at the end away from the card 701. The blocking elements 9 limit the entry distance of the card 701, preventing it from excessively compressing the return spring 703 and causing the return spring 703 to exceed its limit compression distance, thereby improving the service life of the return spring 703.

[0044] A rubber head 8 is fixed to one end of the blocking member 9. The rubber head 8 provides a buffer between the locking member 701 and the blocking member 9 to prevent damage caused by hard compression between the two. Specific Implementation Example 2:

[0046] Reference Figures 1-7In a nighttime simulated operation, staff used the structure disclosed in this utility model to equip eight silent electric drills with the near-infrared lighting device of this utility model. The silent motor body 1 has a power of 850 watts, the LED spotlight 2 uses a 3-watt cold white light source (illuminance of 1200 lux), and the infrared lighting lamp 201 is a 940-nanometer wavelength LED array (radiation intensity of 350 milliwatts / square centimeter). When the operation team was drilling holes in the concrete wall of the abandoned factory, the operator pressed and held the control button 202 to switch to infrared mode. The four contacts 304 on the back of the module lamp 3 were connected to the contact grooves 305 in the mounting groove 302, and the 940-nanometer infrared light source was activated. At the same time, the operator wore AN / PVS-31A binocular night vision devices (spectral response range of 900-1700 nanometers) to identify the drilling point. When it was necessary to adjust the lighting angle, the movable piece 602 was rotated around the shaft 601 (adjustment range ±15°) so that the infrared light spot accurately covered the Φ20 mm drill bit contact surface. During the mission, LED spotlight 2 unexpectedly malfunctioned. The operator activated the quick replacement procedure: 24V DC power was input to electromagnet 705, and the magnetic force attracted the limiting circle part 704, which drove the connecting rod 702 to compress the reset spring 703 (wire diameter 1.2 mm, compression amount 0.6 mm). The auxiliary arc surface 706 of the locking part 701 retracted into the inner wall of the silent motor body 1, disengaging from the fixing grooves 7 (groove depth 3.5 mm) on both sides of the module light 3. The operator pinched the two sides of the module light 3 and applied 8 Newtons of force outward. The limiting groove 301 (embedded with nitrile rubber layer 5, thickness 0.8 mm) slid out along the glass fiber reinforced nylon limiting strip 303 (section 2×3 mm) of the mounting groove 302. The protective arc surface 4 (curvature R = 0.5 mm) prevented scratches during disassembly and assembly. After replacing with a new module, it was inserted vertically. The auxiliary arc surface 706 of the locking part 701 was squeezed back by the module. After the fixing groove 7 was aligned, the reset spring 703 pushed the locking part 701 into the locking position (locking force 23 Newtons). Verified by performing 3 consecutive missions (cumulative operation time of 9 hours), the infrared mode shows that the light source is invisible to the naked eye at a distance of 15 meters from the target, the battery life is extended by 40% (compared to the visible light mode), the electromagnet opening and closing life is >10,000 times, the rubber head 8 (Shore hardness 50A) effectively absorbs the impact energy of the card 701 and the stopper 9, and the disassembly and assembly time is <15 seconds / time.

[0047] The working principle of this utility model is as follows: In a normal environment, the user can activate the LED spotlight 2 to provide visible light illumination by controlling the button 202; in a scenario where concealed operation is required, the system switches to the infrared illumination lamp 201 in the 940nm band. The light in this band cannot be detected by the human eye, but it can be captured by infrared night vision glasses to capture the reflected light from the target surface, thus achieving non-exposure illumination.

[0048] The light source module adopts a detachable design. The module lamp 3 slides into the mounting groove 302 through the limiting groove 301 along the limiting strip 303. The contact point 304 contacts the contact groove 305 to conduct electricity. The auxiliary arc surface 706 of the clip 701 contacts the module lamp 3, pushing the clip 701 into the inner wall of the silent motor body 1. The return spring 703 accumulates elastic potential energy under the compression of the clip 701. When the fixing groove 7 passes the clip 701, the return spring 703 releases the elastic potential energy, causing the clip 701 to pop out and embed into the fixing groove 7, thereby fixing the module lamp 3. When working... When personnel need to disassemble module lamp 3, energizing electromagnet 705 causes magnetic attraction to limit circle part 704, causing locking part 701 to enter the inner wall of silent motor body 1, thus allowing personnel to pull out module lamp 3; the angle adjustment function is achieved by moving piece 602 rotating around shaft part 601 in moving groove 6, allowing infrared lighting lamp 201 to be finely adjusted by ±15 degrees to adapt to different drilling angles. Protective arc surface 4 and rubber layer 5 buffer the impact of module lamp 3 insertion and removal, and rubber head 8 absorbs the collision energy of locking part 701 and blocking part 9, ensuring long-term stability.
