Description

Technical Field

[0001] The invention relates to the technical field of searchlights, in particular to a portable multifunctional searchlight. Background Art

[0002] A portable multifunctional searchlight is a kind of lighting equipment that is easy to carry. It usually has a high brightness and can provide users with a strong focused light source. It is widely used in outdoor activities, emergency rescue, night work, vehicle maintenance and other occasions.

[0003] When lighting is needed in a mine, since open flames cannot be used in mines, lighting equipment such as searchlights are usually used. The existing searchlights have relatively simple functions, which are divided into strong light for long-distance detection and weak light for short-distance detection. When it is necessary to change from far to near, the irradiation direction and angle are generally adjusted by turning the hand. At this time, when strong light changes from irradiating far to irradiating near, the light is too bright and dazzling, and will interfere with the vision of others. When weak light changes from irradiating near to irradiating far, the light is relatively blurred, making it difficult to clearly identify distant objects.

[0004] In response to the above problems, the prior art has proposed a variety of solutions, such as a searchlight with patent number CN201910325752.8, which can be easily installed on various parts of the user's body through a switching mechanism, which is convenient for use in different situations, and can switch between energy-saving small-range lighting and power-consuming large-range lighting. However, the switching process is mainly through adjusting the number of light bulbs that emit light. When the low beam is irradiated, as the distance gets closer, the irradiated halo becomes smaller and smaller. At this time, the light intensity increases while the area formed by the light decreases. At this time, although the reduction of bulbs will reduce the light intensity of the light source, the reduction in light intensity will further reduce the area illuminated by the searchlight, which is difficult to meet the requirements of the irradiated area for low beam lighting in the mine.

[0005] Based on this, in order to solve the problem that it is difficult to increase or even maintain the area of ​​the irradiation area when the searchlight in the mine changes from long-distance irradiation to close-distance irradiation, thereby affecting the searchlight's lighting effect at close range, the present invention designs a portable multifunctional searchlight. Summary of the invention

[0006] The invention provides a portable multifunctional searchlight; it solves the problem that when the searchlight in a mine cave changes from long-distance irradiation to short-distance irradiation, it is difficult to increase or even maintain the area of ​​the irradiation area, thereby affecting the near-range lighting effect of the searchlight; by changing the holding distance of the handle to control the irradiation angle of the light source, and then using the reflective optical principle, the appropriate irradiation range and light intensity of the searchlight under different situations are formed.

[0007] In order to achieve the above object, the present invention provides the following technical solutions:

[0008] The present invention provides a portable multifunctional searchlight, comprising a base, a gripping portion, and a head, wherein the gripping portion is mounted on the base, a lamp holder, a bulb, and a glass cover are mounted on the head, a reflective cup is mounted on the front end of the lamp holder, a driving mechanism is mounted between the gripping portion and the head, an adjusting plate is mounted inside the reflective cup, a switching mechanism is mounted on the adjusting plate, when high beam is switched to low beam, the driving mechanism drives the end of the adjusting plate to move backward, and a plurality of the adjusting plates change from a dispersed state to a gathered state, when the end of the adjusting plate moves toward the light source, the switching mechanism is driven to adjust the direction of light irradiated from the bulb, and the searchlight function is adjusted by the driving mechanism, and the searchlight in the present application can switch between three modes.

[0009] Preferably, the driving mechanism includes a slide groove, a telescopic plate, a connecting rod, and a fixed ring. The slide groove is opened on the lamp holder, the telescopic plate is installed in the slide groove, one end of the connecting rod is installed at the front end of the telescopic plate, the adjustment plate is installed between the telescopic rod and the fixed ring, and the fixed ring is installed at the front end of the head. The connecting rod can be driven by an electric push rod, but manual adjustment saves battery power.

[0010] Preferably, the bottom of the reflective cup is connected to the end of the telescopic plate, and the reflective cup moves synchronously when the telescopic plate moves forward, which can ensure that no light leaks during high beam irradiation. A special structure of the adjustment plate can also be provided so that the folded reflective films between the two can be unfolded when it becomes a parabola to achieve high beam irradiation.

[0011] Preferably, when the telescopic plate moves to the rightmost end, the adjustment plate is in a straightened state, and the adjustment plates are in contact with each other. When the telescopic plate moves to the leftmost end, there is a gap between the adjustment plates, and the gap can be used to transform the searchlight into a camping light, thereby improving functional diversity.

[0012] Preferably, the glass cover is in the shape of a plane and a spherical surface. The glass cover is sleeved outside the fixing ring and is rotatably connected to the fixing ring. The spherical surface of the glass cover is frosted. The edge of the plane is for long-distance irradiation, and the frosted spherical surface is convenient for range irradiation.

[0013] Preferably, the grasping part is composed of a free section and a fixed section, the end of the free section facing away from the fixed section is connected to the other end of the connecting rod, and a lock is installed at the free end of the free section. Through the free section and the fixed section, the hand holding posture can be changed, so that the head can be pressed when the low beam is used, and the middle part can be held when the high beam is used, so that the two ends are balanced.

[0014] Preferably, the reflective cup is rotatably connected to the lamp holder, and the head outside the reflective cup is transparent, so that light can be transmitted outward through the head, thereby expanding the illumination range of the searchlight.

[0015] Preferably, the switching mechanism includes a limit slot, a light-changing slice, and a convex block. The limit slot is provided inside the lamp holder, the light-changing slice is installed in the limit slot, the convex block is installed above the light-changing slice, the convex block is connected to the bottom of the telescopic plate, the convex block includes a fixed portion and a movable portion, a reset spring is installed between the fixed portion and the movable portion, and the use of an articulated rod is not limited here, the other end of the articulated rod is connected to the fixed portion, and the hinge point of the articulated rod is located on the base.

[0016] Preferably, the longitudinal cross-section of the light-changing slice is a corrugated tube shape, and the transverse cross-section of the light-changing slice is a wave shape. The transverse cross-section of the light-changing slice is divided into an edge segment and a center segment. When the adjustment plate is straightened, the tangent of the center segment is parallel to the straight line where the adjustment plate is located directly below, thereby achieving clear lighting in the near area and avoiding the problem of user discomfort caused by excessive light reflection through the inclined surface.

[0017] Preferably, the adjustment plate is provided with an inclined surface, and the angle between the inclined surface and the plane where the adjustment plate section is located is 45°, which can make the light emitted from the adjustment plate diffuse to all sides, so that the light will not irradiate along a fixed direction.

[0018] The beneficial effects of the present invention are as follows:

[0019] 1. The portable multifunctional searchlight proposed in the present invention can be combined into a variety of different lighting modes of the searchlight through the disassembly and assembly of the reflective cup and the adjustment of the grip portion, thereby improving the convenience of using the searchlight. At the same time, under the action of the adjustment mechanism, the angle of the light can be changed, and when forming a low beam lamp and a desk lamp-like lamp, the light can be concentrated to a lower position, thereby reducing the impact of the low beam lamp and the desk lamp light on distant areas.

[0020] 2. The present invention proposes a portable multifunctional searchlight, in which a connecting rod is driven to move by a grip portion, and the connecting rod drives the telescopic plate to move backward, thereby driving the adjustment plate to be straightened. In the process of straightening, the gaps between the adjustment plates are gradually filled, and adjacent adjustment plates are fitted together to form a sealed ring-shaped cone. At this time, the light emitted by the bulb is blocked by the adjustment plates, and then diffused outward along the conical surface formed by the adjustment plates, which can provide a more uniform light distribution, thereby increasing the illuminated area of ​​the illuminated area.

[0021] 3. The present invention proposes a portable multifunctional searchlight. When the telescopic plate moves backward, it drives the other end of the hinged rod to move forward, thereby driving the fixed part and the movable part to move forward synchronously. Under the elastic expansion and contraction of the reset spring, the dimming slice gradually blocks the bulb, thereby focusing the light downward. On the one hand, it changes the irradiation angle of the light from high beam to low beam. On the other hand, a part of the light is absorbed by the dimming slice, thereby weakening the intensity of the light. It can also make the light irradiate to the ground when the searchlight is held horizontally, thereby achieving the effect of close-up illumination. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0033] In order to better understand the above solution, the above technical solution is described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0034] like Figure 1-2 As shown, a portable multifunctional searchlight provided by the present invention comprises a base 1, a gripping portion 2, and a head 3, wherein the gripping portion 2 is mounted on the base 1, and a lamp holder 31, a bulb 32, and a glass cover 33 are mounted on the head 3, and a reflective cup 4 is mounted on the front end of the lamp holder 31, and the curvature of the reflective cup 4 is the maximum value of a traditional searchlight, so that when the adjustment plate 6 is switched, it can rely on the reflection of the reflective cup 4 to form long-distance light, thereby increasing the irradiation distance of the searchlight; a driving mechanism 5 is mounted between the gripping portion 2 and the head 3, an adjusting plate 6 is mounted inside the reflective cup 4, and a switching mechanism 7 is mounted on the adjusting plate 6, and when the high beam is switched to the low beam, the driving mechanism 5 drives the end of the adjusting plate 6 to move backward, and the multiple adjusting plates 6 change from a dispersed state to a gathered state, and when the end of the adjusting plate 6 moves toward the light source, it drives the switching mechanism 7 to adjust the direction of the light irradiated by the bulb 32.

[0035] When the telescopic plate 52 moves to the rightmost end, the adjustment plates 6 are in a straightened state, and the adjustment plates 6 fit together. When the telescopic plate 52 moves to the leftmost end, there is a gap between the adjustment plates 6.

[0036] The searchlight function is adjusted by the driving mechanism 5. The searchlight in the present application has three basic functions. The first is long-distance searchlight. By using the principle of reflective optics, the light emitted by the bulb 32 can be reflected along the reflective cup 4. As the curvature increases, the focal distance in the reflective cup 4 becomes shorter and shorter, and the light beam will be irradiated in a more concentrated direction, thereby forming a strong focused light beam, so that the irradiation distance is longer, and the general situation in the long-distance mine cave can be detected to ensure the safety of the user.

[0037] The second type is a short-range searchlight. At this time, the grip 2 moves toward the tail of the searchlight and is fixed by the lock buckle 211 to form a bent shape. At this time, the user can put his thumb on the free section 21 of the grip 2 and control the downward tilt angle of the head 3 by pressing, so as to facilitate the adjustment of the position of the head 3 when searching with low beam. Compared with high beam searchlight, low beam lights illuminate the surroundings and the ground. Therefore, the convenience of using the searchlight is improved by switching the position of the grip 2.

[0038] The third type is a hanging camping lamp. The glass cover 33 is unscrewed, the reflector cup 4 is taken out, and the glass cover 33 is tightened. At this time, the searchlight is hung upward from the base 1. Since there is a gap between the adjustment plates 6 when they are bent, and the reflector cup 4 is lost, it will shine around the searchlight through the gap, and then cooperate with the glass cover 33 to form a camping lamp with surrounding light, so as to realize fixed-point detection of a local area. When the adjustment plate 6 is not bent, the light will be blocked by the adjustment plate 6 and diffuse in a cone along the edge of the adjustment plate 6, thus forming a light similar to a desk lamp.

[0039] By disassembling and assembling the reflective cup 4 and adjusting the grip 2, four different lighting modes of the searchlight can be combined, thereby improving the convenience of using the searchlight. At the same time, under the action of the adjustment mechanism, the angle of the light can be changed, and when forming a low beam or a table lamp, the light can be concentrated to a lower position, thereby reducing the impact of the low beam and the table lamp on distant areas.

[0040] like Figure 3 As shown, the driving mechanism 5 includes a slide groove 51, a telescopic plate 52, a connecting rod 53, and a fixing ring 54. The slide groove 51 is opened on the lamp holder 31, the telescopic plate 52 is installed in the slide groove 51, one end of the connecting rod 53 is installed at the front end of the telescopic plate 52, the adjustment plate 6 is installed between the telescopic rod and the fixing ring 54, and the fixing ring 54 is installed at the front end of the head 3.

[0041] During the movement of the grip portion 2, the bottom end of the grip portion 2 drives the connecting rod 53 in the slide groove 51 to move synchronously. The connecting rod 53 is L-shaped. When the grip portion 2 is driven by the user to move forward and backward, the telescopic plate 52 will also move forward and backward synchronously, thereby driving the distance between the telescopic plate 52 and the fixing ring 54 to change. At this time, the telescopic plate 52 will drive the adjustment plate 6 to bend. The adjustment plate 6 can be a reflective film, which can bend under extrusion, and then the connecting rod 53 drives the telescopic plate 52 to bend. When the plate 52 moves toward the head 3, the reflective film will bend outward, gradually increasing the curvature of the reflective film. As the telescopic plate 52 gradually moves forward, the adjustment plate 6 is constrained by the reflective cup 4 and gradually moves closer to the inner wall of the reflective cup 4, and then forms an integral type with the inner wall of the reflective cup 4. That is, when the adjustment plate 6 is fully unfolded, the light emitted by the bulb 32 is reflected on the inner wall of the adjustment plate 6 and the reflective cup 4, and the adjustment plate 6 fits the reflective cup 4, thereby forming reflected light with the same curvature, and then can illuminate the distant;

[0042] When it is necessary to adjust the low beam, the connecting rod 53 is moved by the grip 2, and the connecting rod 53 drives the telescopic plate 52 to move backward, thereby driving the adjustment plate 6 to be straightened. During the straightening process, the gaps between the adjustment plates 6 are gradually filled, and the adjacent adjustment plates 6 are fitted together to form a sealed ring-shaped cone. At this time, the light emitted by the bulb 32 is blocked by the adjustment plate 6, and then diffuses outward along the conical surface formed by the adjustment plate 6, which can provide a more uniform light distribution, and compared with the internal parabolic reflective cup 4, its focusing effect at a long distance is poor, thereby increasing the area of ​​the short-range illumination area and reducing the light intensity of the local area at a short distance.

[0043] The bottom of the reflective cup 4 is connected to the end of the telescopic plate 52 , and when the telescopic plate 52 moves forward, the reflective cup 4 moves synchronously.

[0044] The reflective cup 4 is connected to the end of the telescopic plate 52, so that the adjustment plate 6 can fit the reflective cup 4 exactly when bent to the limit. At this time, the light emitted by the bulb 32 will be refracted by the inner wall of the telescopic plate 52 and the inner wall of the reflective cup 4, thereby improving the light gathering effect when long-distance searchlighting is required, and then the light can be reflected from a point light source and propagated in a specific direction, thereby increasing the illumination distance and brightness.

[0045] The glass cover 33 is in the shape of a plane and a spherical surface. The glass cover 33 is sleeved on the outside of the fixing ring 54 and is rotatably connected to the fixing ring 54 . The spherical surface of the glass cover 33 is frosted.

[0046] When the searchlight is transformed into a camping lamp, the flat glass cover 33 can be replaced with a spherical one to increase the diffuse reflection effect of the light. At the same time, when the telescopic plate 52 moves backward, the light is gathered downward, and the spherical glass cover 33 allows the light to be continuously emitted from one direction. The diffuse reflection is used to transform the light into a soft halo, thereby increasing the illumination range of the light around the searchlight and reducing the light intensity.

[0047] like Figure 4 As shown, the grip portion 2 is divided into a free section 21 and a fixed section 22. The end of the free section 21 facing away from the fixed section 22 is connected to the other end of the connecting rod 53. A lock buckle 211 is installed at the free end of the free section 21. The free section 21 is a double connecting rod 53 mechanism. When both ends are fixed, the double connecting rod 53 is also fixed, thereby forming a locked state.

[0048] The locking of the free section 21 is achieved by the lock buckle 211. The lock buckle 211 is a latch and a notch. The notch is provided on the upper surface of the base 1. The latch is installed on the free section 21. There can be multiple notches. As the free section 21 moves forward and backward, the latch is driven to move synchronously. By pressing the latch, the latch can be fixed at the notch, thereby achieving the effect of fixing the telescopic plate 52, thereby fixing the reflection angle and brightness of the light source, so as to facilitate the stable illumination of the light source. When adjustment is needed, only the latch needs to be pulled out, and the thumb can be used to adjust the free section 21 to adjust the light angle and brightness.

[0049] like Figure 6-7 As shown, the reflective cup 4 is rotatably connected to the lamp holder 31, and the head 3 outside the reflective cup 4 is transparent.

[0050] After the reflective cup 4 is removed, the light can be transmitted outward through the distance between the adjustment plates 6 by the illumination of the bulb 32. At this time, the head 3 outside the reflective cup 4 is transparent, and the light can be transmitted outward through the head 3, thereby expanding the illumination range of the searchlight, and also enabling the light to be illuminated at multiple angles, thereby avoiding light aggregation to form strong light and affect people's vision.

[0051] like Figure 4-5 As shown, the switching mechanism 7 includes a limiting groove 71, a light-changing slice 72, and a convex block 73. The limiting groove 71 is opened inside the lamp holder 31, the light-changing slice 72 is installed in the limiting groove 71, and the convex block 73 is installed above the light-changing slice 72. The convex block 73 is connected to the bottom of the telescopic plate 52. The convex block 73 includes a fixed portion 731 and a movable portion 732. A return spring 733 is installed between the fixed portion 731 and the movable portion 732. A hinge rod 74 is installed at the telescopic plate 52. The other end of the hinge rod 74 is connected to the fixed portion 731, and the hinge point of the hinge rod 74 is located on the lamp holder 31. Both ends of the hinge rod 74 can be retracted to avoid interference during retraction.

[0052] When the telescopic plate 52 moves, the telescopic plate 52 will drive the light-changing slice 72 in the limiting groove 71 to move, and the fixed portion 731 is connected to the telescopic plate 52. When the telescopic plate 52 moves forward, the telescopic plate 52 will drive the hinge rod 74 to rotate around the hinge point, and the other end of the hinge rod 74 moves backward, driving the fixed portion 731 to move backward synchronously. At this time, the movable portion 732 in the fixed portion 731 will also move backward. However, at this time, the limiting groove 71 is an arc, and the light-changing slice 72 will slide inward along the arc, gradually releasing the light from the bulb 32. On the contrary, when the telescopic plate 52 moves backward, it drives the other end of the hinged rod 74 to move forward, and then drives the fixed part 731 and the movable part 732 to move forward synchronously. Under the elastic expansion and contraction of the reset spring 733, the dimming slice 72 gradually blocks the bulb 32, so that the light is gathered downward. On the one hand, it changes the irradiation angle of the light from high beam to low beam, and on the other hand, a part of the light is absorbed by the dimming slice 72, thereby weakening the intensity of the light. It can also make the light irradiate to the ground when the searchlight is held horizontally, thereby achieving the effect of close-up.

[0053] like Fig. 9 As shown, the longitudinal section of the light-changing slice 72 is a corrugated tube, the transverse section of the light-changing slice 72 is a wave, and the transverse section of the light-changing slice 72 is divided into an edge section 721 and a center section 722. When the adjustment plate 6 is straightened, the tangent of the center section 722 is parallel to the straight line where the adjustment plate 6 is located directly below.

[0054] When the adjustment plate 6 is straightened, the light-changing slice 72 is folded forward to the maximum position. At this time, the tangent of the central segment 722 is parallel to the straight line where the adjustment plate 6 is located directly below, so that the light emitted from the bulb 32 can be emitted as parallel light, thereby providing a more uniform light distribution range, achieving clear lighting in the near area, and avoiding the problem of excessive light causing discomfort to the user.

[0055] like Figure 8 As shown, the adjusting plate 6 is provided with an inclined surface 61, and the angle between the inclined surface 61 and the plane where the section of the adjusting plate 6 is located is 45°.

[0056] When used as a camping lamp, the light will flow outward through the gaps between the adjustment plates 6. The reflection of the inclined surface 61 can make the light emitted from the adjustment plates 6 diffuse to the surroundings, so that the light will not irradiate in a fixed direction, thereby increasing the irradiation range of the light and improving the diversity of the use functions of the searchlight.

[0057] Under normal circumstances, the searchlight can be a low beam light, so as to avoid direct light exposure to the eyes of people in front and causing damage when it is turned on. At this time, the free section 21 and the fixed section 22 of the handle 2 are horizontal. When the user needs to adjust to the high beam, the lock 211 is opened, and the free section 21 is pushed, so that the handle 2 gradually becomes horizontal. At this time, the staff adjusts the hand posture to a gripping state, and then searches the distance.

[0058] The light bulb 32 is turned on by the power switch, and the light bulb 32 shines on the reflective cup 4 and the adjustment plate 6. At this time, the light is bent and then focused to a distant focus to increase the illumination distance. The specific method is to open the lock buckle 211, push the free section 21, and the free section 21 drives the connecting rod 53 to move. The connecting rod 53 drives the telescopic plate 52 to slide in the slide groove 51, and then the telescopic plate 52 will gather the light and transmit it outward. The inner surface of the telescopic plate 52 is a reflective surface, so that the light can be evenly irradiated and then transmitted to the reflective cup 4 and the adjustment plate 6. During the movement of the telescopic plate 52, the adjustment plate 6 will be pushed to move to the front end. At this time, the adjustment plate 6 is transformed from a straight rod to a parabolic rod, and as the telescopic plate 52 moves forward, the parabolic curvature of the telescopic plate 52 is closer to the parabolic curvature of the reflective cup 4, until they are the same. Then, when the telescopic plate 52 is extended to the front end, the reflective cup 4 and the adjustment plate 6 can form an arc surface similar to the reflective cup 4, so as not to interfere with the long-distance searchlight of the light.

[0059] When the destination is reached and the headlight needs to be adjusted to low beam, the lock buckle 211 is unlocked and the free section 21 is subsequently slid, driving the connecting rod 53 to move in the reverse direction. The connecting rod 53 drives the telescopic plate 52 to slide backward, and the adjusting plate 6 is straightened from a parabola at the same time. After straightening, the edge of the adjusting plate 6 just fits in place, and the light of the bulb 32 is refracted along the adjusting plate 6, so that uniform light can be emitted, thereby increasing the range of illumination. At the same time, the telescopic plate 52 simultaneously drives the hinged rod 74 to rotate, and the hinged rod 74 drives the fixed portion 731 connected thereto to move forward, and the compensation of the reset spring 733 and the movable portion 732 causes the light-changing slice 72 to fold forward, thereby blocking the bulb 32. On the one hand, it absorbs a certain amount of light source, and on the other hand, it constrains the direction of the light source, thereby ensuring that the light can illuminate the ground.

[0060] When it is needed to be used as a camping lamp, the light source is turned off, the glass cover 33 is unscrewed, the reflector cup 4 is disassembled, and then the telescopic plate 52 is moved to the front end, the spherical glass cover 33 is installed, and then the searchlight is hung from the rear end to achieve the effect of a camping lamp.

[0061] The basic principles and beneficial effects of the present invention are shown and described above. At the same time, the present invention is not limited to the above embodiments. Without departing from the effects and scope of the present invention, the present invention may have various changes and improvements.
