Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of searchlights, and more specifically to a portable multi-functional searchlight. Background Art
[0002] A portable multi-functional searchlight is a lighting device that is easy to carry. It usually has a high brightness and can provide a strong focused light source for users. It is widely used in outdoor activities, emergency rescue, night work, vehicle maintenance and other occasions.
[0003] When lighting is required in a mine, since open flames cannot be used in the mine, lighting devices such as searchlights are usually used. However, the existing searchlights have relatively single functions, which are divided into strong light for detecting long distances and weak light for detecting short distances. When it is necessary to change from a long distance to a short distance, the irradiation direction and irradiation angle are generally adjusted by rotating the hand. At this time, when the strong light changes from irradiating a long distance to irradiating a short distance, the light is too bright and dazzling, and it will interfere with the line of sight of others. When the weak light changes from irradiating a short distance to irradiating a long distance, the light is relatively blurred, and it is difficult to clearly identify things in the distance.
[0004] In response to the above problems, various solutions have been proposed in the prior art. For example, a searchlight with a patent number of CN201910325752.8 can be conveniently installed at various parts of the user's body through a switching mechanism, which is convenient for use in different situations, and can be switched between power-saving small-range lighting and power-consuming large-range lighting. However, the switching process mainly adjusts the number of bulbs that emit light. When irradiating with near light, as the distance gets closer and closer, the irradiation halo becomes smaller and smaller. At this time, while the light intensity increases, the area of the region formed by the light decreases. Although reducing the number of bulbs will reduce the light intensity of the light source, the reduction of the light intensity will further reduce the area of the region irradiated by the searchlight, making it difficult to meet the requirements of the near-light illumination in the mine for the irradiated area.
[0005] Based on this, in order to solve the problem that when the searchlight in the mine changes from long-distance irradiation to short-distance irradiation, it is difficult to increase or even maintain the area of the irradiated region, which in turn affects the near-light illumination effect of the searchlight, the present invention designs a portable multi-functional searchlight. Summary of the Invention
[0006] The portable multi-functional searchlight provided by the present invention solves the problem that when the searchlight in the mine changes from long-distance irradiation to short-distance irradiation, it is difficult to increase or even maintain the area of the irradiated region, which in turn affects the near-light illumination effect of the searchlight. By changing the holding distance of the handle, the irradiation angle of the light source is controlled, and then by using the principle of reflective optics, a suitable irradiation range and light intensity of the searchlight in 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 limiting groove, a light-changing slice, and a convex block. The limiting groove is formed inside the lamp holder. The light-changing slice is installed in the limiting groove. 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 part and a movable part. A return spring is installed between the fixed part and the movable part. It is not limited to using a hinge rod here. The other end of the hinge rod is connected to the fixed part. The hinge point of the hinge rod is located on the base. Other methods can also be used, such as a gear rack, as long as the forward telescopic rod and the light-changing slice can move in the opposite direction are achieved.
[0016] Preferably, the longitudinal section of the light-changing slice is in the shape of a corrugated pipe, and the transverse section of the light-changing slice is in the shape of a wave. The transverse section of the light-changing slice is divided into an edge section and a center section. When the adjusting plate is straightened, the tangent of the center section is parallel to the straight line where the adjusting plate is located directly below, realizing clear illumination in the nearby area and at the same time avoiding the problem that the user feels uncomfortable due to the over-bright light after being reflected by the inclined plane.
[0017] Preferably, the adjusting plate is provided with an inclined plane, and the included angle between the inclined plane and the plane where the cutting surface of the adjusting plate is located is 45°. This can make the light emitted along the adjusting plate diffuse around, so that the light does not irradiate in a fixed direction.
[0018] The beneficial effects of the present invention are as follows:
[0019] 1. A portable multi-functional searchlight proposed by the present invention can be combined into various different lighting modes of the searchlight through the disassembly and assembly of the reflector cup and the adjustment of the holding part, thereby improving the convenience of use of the searchlight. At the same time, under the action of the adjustment mechanism, the angle of the light emitted by the lamp can be changed, so that when forming a low beam and a desk lamp-like light, the light can be concentrated and irradiated to a position slightly below, thereby reducing the influence of the low beam and desk lamp light on the distant area.
[0020] 2. A portable multi-functional searchlight proposed by the present invention drives the connecting rod to move through the holding part, the connecting rod drives the telescopic plate to move backward, and then drives the adjusting plate to be straightened. During the straightening process, the gaps between the adjusting plates will be gradually filled, and adjacent adjusting plates will be attached to each other in pairs, thereby forming a sealed annular cone. At this time, the light emitted by the bulb is blocked by the adjusting plate and diffuses outward along the cone surface formed by the adjusting plates. It can provide a relatively uniform light distribution, thereby increasing the illumination area of the illuminated area.
[0021] 3. For the portable multi-functional searchlight proposed by the present invention, when the telescopic plate moves backward, it drives the other end of the hinge rod to move forward, and further drives the fixed part and the movable part to move forward synchronously. Under the elastic expansion and contraction of the return spring, the light-changing slice gradually blocks the light bulb, so that the light is gathered downward. On the one hand, the irradiation angle of the light is changed from the high beam to the low beam. On the other hand, part of the light is absorbed by the light-changing slice, thus weakening the intensity of the light. It can also make the light shine on the ground when the searchlight is held horizontally, achieving the effect of close illumination. BRIEF DESCRIPTION OF THE DRAWINGS

[0033] To better understand the above solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings of the specification and the specific implementation manner.
[0034] As Figure 1-2 shown, a portable multi-functional searchlight provided by the present invention includes a base 1, a grasping part 2, and a head 3. The grasping part 2 is installed on the base 1, and a lamp holder 31, a bulb 32, and a glass cover 33 are installed at the head 3. A reflector cup 4 is installed at the front end of the lamp holder 31. The curvature of the reflector cup 4 is the maximum value of a traditional searchlight. Thus, when the adjusting plate 6 is switched, it can rely on the reflection of the reflector cup 4 to form a long-distance light, thereby improving the irradiation distance of the searchlight; a driving mechanism 5 is installed between the grasping part 2 and the head 3. An adjusting plate 6 is installed inside the reflector cup 4, and a switching mechanism 7 is installed at the adjusting plate 6. When switching from a high beam to a low beam, the driving mechanism 5 drives the end of the adjusting plate 6 to move backward, and the plurality of adjusting plates 6 change from a dispersed state to a converged state. When the end of the adjusting plate 6 moves towards the light source, it drives the switching mechanism 7 to adjust the light direction irradiated at the bulb 32.
[0035] When the telescopic plate 52 moves to the rightmost end, the adjusting plate 6 is in a straightened state. At this time, the adjusting plates 6 are in contact with each other. When the telescopic plate 52 moves to the leftmost end, there is a gap between the adjusting plates 6.
[0036] The adjustment of the searchlight function is realized through the driving mechanism 5. The basis of the searchlight in this application has three functions. The first is the long-distance searchlight. Using the principle of reflective optics, the light emitted by the bulb 32 can be reflected along the reflector cup 4. As the curvature increases, the focal distance inside the reflector cup 4 becomes shorter and shorter, and the light beam will be irradiated more in a concentrated direction, thereby forming a strong focused light beam, making the irradiation distance farther, and thus being able to detect the general situation in a long-distance mine tunnel to ensure the safety of the user;
[0037] The second type is the close-range searchlight. At this time, the grip part 2 moves towards the tail of the searchlight and forms a bent shape after being fixed by the latch 211. At this time, the user can place the thumb on the free section 21 of the grip part 2, and the angle of the head 3 tilting downward can be controlled by pressing, so as to facilitate adjusting the position of the head 3 when searching for the low beam. Compared with the high beam searchlight, the low beam lamp illuminates the surrounding area and the ground. Therefore, the convenience of using the searchlight is improved by switching the position of the grip part 2;
[0038] The third type is the hanging camping lamp. By unscrewing the glass cover 33, then taking out the reflector cup 4, and screwing the glass cover 33 tightly, at this time, the searchlight is hung upward from the base 1. Since there are gaps between the adjusting plates 6 when they are bent and there is no blockage of the reflector cup 4, it will irradiate around the searchlight through the gaps, and then cooperate with the glass cover 33 to form a camping lamp that emits light around, so as to realize fixed-point detection of a local area. When the adjusting plates 6 are not bent, at this time, blocked by the adjusting plates 6, the light will spread in a conical shape along the edges of the adjusting plates 6, thus forming a light similar to that of a table lamp;
[0039] Through the disassembly and assembly of the reflector cup 4 and the adjustment of the grip part 2, four different lighting modes of the searchlight can be combined, thus improving the convenience of using the searchlight. At the same time, under the action of the adjustment mechanism, the angle of the light emitted can be changed, so that when forming the low beam lamp and the table lamp, the light can be concentrated and directed to the lower position, thus reducing the influence of the low beam lamp and the table lamp light on the distant area.
[0040] As Figure 3 shown, the driving mechanism 5 includes a chute 51, a telescopic plate 52, a connecting rod 53, and a fixing ring 54. The chute 51 is opened on the lamp base 31, the telescopic plate 52 is installed in the chute 51, one end of the connecting rod 53 is installed at the front end of the telescopic plate 52, the adjusting 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 gripping part 2, the bottom end of the gripping part 2 will drive the connecting rod 53 in the sliding groove 51 to move synchronously. The connecting rod 53 is L-shaped. When the gripping part 2 moves back and forth under the drive of the user, the telescopic plate 52 will also move back and forth synchronously, thereby driving the distance between the telescopic plate 52 and the fixed ring 54 to change. At this time, the telescopic plate 52 will drive the adjusting plate 6 to bend. The adjusting plate 6 can be a reflective flexible sheet, which can be bent under extrusion. Therefore, when the connecting rod 53 drives the telescopic plate 52 to move towards the head 3, the reflective flexible sheet will bend outward, gradually increasing the curvature of the reflective flexible sheet. As the telescopic plate 52 moves forward step by step, restricted by the reflector cup 4, the adjusting plate 6 gradually approaches the inner wall of the reflector cup 4 and forms an integral body with the inner wall of the reflector cup 4. That is, when the adjusting plate 6 is fully unfolded, the light emitted by the bulb 32 is reflected on the inner wall of the adjusting plate 6 and the reflector cup 4. The adjusting plate 6 is in contact with the reflector cup 4, thereby forming reflected light with the same curvature, and then can search the distance.
[0042] When adjusting the low beam, the connecting rod 53 is driven to move by the gripping part 2. The connecting rod 53 drives the telescopic plate 52 to move backward, thereby driving the adjusting plate 6 to be straightened. During the straightening process, the gaps between the adjusting plates 6 will be gradually filled. The adjacent adjusting plates 6 are in contact with each other in pairs, thereby forming a sealed annular cone. At this time, the light emitted by the bulb 32 is blocked by the adjusting plate 6 and then diffuses outward along the cone surface formed by the adjusting plate 6. It can provide a relatively uniform light distribution. And compared with the reflector cup 4 with an internal parabolic surface, its focusing effect at a long distance is poor, thereby increasing the area of the close-range illumination area and weakening the illumination intensity of the local area at close range.
[0043] The bottom of the reflector cup 4 is connected to the end of the telescopic plate 52. When the telescopic plate 52 moves forward, the reflector cup 4 moves synchronously.
[0044] The connection between the reflector cup 4 and the end of the telescopic plate 52 can make the adjusting plate 6 just fit the reflector cup 4 when bent to the limit. At this time, the light emitted by the bulb 32 will be refracted on the inner wall of the telescopic plate 52 and the inner wall of the reflector cup 4, thereby improving the focusing effect of the light when a long-distance search is needed. Then the light can be reflected from a point light source and propagated along a specific direction, thereby increasing the irradiation distance and brightness.
[0045] The shape of the glass cover 33 is a plane and a spherical surface. The glass cover 33 is sleeved outside the fixed ring 54 and is rotatably connected to the fixed ring 54. The spherical glass cover 33 is frosted.
[0046] When the searchlight is transformed into a camp light, the flat glass cover 33 can be replaced with a spherical surface at this time, thereby increasing the diffuse reflection effect of the light. At the same time, when the telescopic plate 52 moves backward, the light is concentrated downward at this time. Through the spherical glass cover 33, the light is continuously emitted from one direction, and the diffuse reflection is used to transform the light into a soft halo, thereby increasing the lighting range around the searchlight and weakening the light intensity.
[0047] As Figure 4 shown, the gripping part 2 is divided into a free section 21 and a fixed section 22. One end of the free section 21 away from the fixed section 22 is connected to the other end of the connecting rod 53, and a lock 211 is installed at the free end of the free section 21. The free section 21 is a double-link 53 mechanism. When fixed at both ends, the double-link 53 is also fixed, thereby forming a locked state.
[0048] The locking of the free section 21 is achieved through the lock 211. The lock 211 is a bolt and a notch. The notch is opened on the upper surface of the base 1, and the bolt is installed on the free section 21. Multiple notches can be provided at this place. As the free section 21 moves back and forth, the bolt is driven to move synchronously. By pressing the bolt, the bolt can be fixed at the notch, thereby achieving the effect of fixing the telescopic plate 52, and then fixing the reflection angle and brightness of the light source, so as to facilitate the stable irradiation of the light source. When adjustment is needed, only the bolt needs to be pulled out, and the free section 21 can be adjusted by the thumb to adjust the light angle and brightness.
[0049] As Figures 6-7 shown, the reflector cup 4 is rotatably connected to the lamp base 31, and the head 3 outside the reflector cup 4 is transparent.
[0050] After the reflector cup 4 is disassembled, the light can be transmitted outward through the distance between the adjusting plates 6 by the irradiation of the bulb 32. At this time, the head 3 outside the reflector cup 4 is transparent, and the light can be transmitted outward through the head 3, thereby expanding the lighting range of the searchlight and also enabling the light to be irradiated at multiple angles, avoiding the concentration of light to form strong light and affecting people's vision.
[0051] As Figures 4-5 shown, the switching mechanism 7 includes a limit groove 71, a light-changing slice 72, and a convex block 73. The limit groove 71 is opened inside the lamp base 31, the light-changing slice 72 is installed in the limit groove 71, 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 part 731 and a movable part 732, a return spring 733 is installed between the fixed part 731 and the movable part 732, a hinge rod 74 is installed at the telescopic plate 52, and the other end of the hinge rod 74 is connected to the fixed part 731. The hinge point of the hinge rod 74 is located on the lamp base 31. The ends of the hinge rod 74 can all contract, thereby avoiding interference during contraction.
[0052] During the movement of the telescopic plate 52, the telescopic plate 52 drives the light-changing slice 72 in the limiting groove 71 to move. The fixing part 731 is connected to the telescopic plate 52. When the telescopic plate 52 moves horizontally forward, the telescopic plate 52 drives the hinge rod 74 to rotate around the hinge point. The other end of the hinge rod 74 moves backward, driving the fixing part 731 to move horizontally backward synchronously. At this time, the movable part 732 in the fixing part 731 also moves backward. However, at this time, the limiting groove 71 is arc-shaped, and thus the light-changing slice 72 slides inward along the arc, gradually releasing the blockage of the light of the bulb 32. On the contrary, when the telescopic plate 52 moves backward, it drives the other end of the hinge rod 74 to move forward, thereby driving the fixing part 731 and the movable part 732 to move forward synchronously. Under the elastic expansion and contraction of the return spring 733, the light-changing slice 72 gradually blocks the bulb 32, so that the light is concentrated downward. On the one hand, the irradiation angle of the light is changed from high beam to low beam. On the other hand, part of the light is absorbed by the light-changing slice 72, thereby weakening the intensity of the light. It can also make the light shine on the ground when the searchlight is held horizontally, achieving the effect of near illumination.
[0053] As Figure 9 shown, the longitudinal section of the light-changing slice 72 is bellows-shaped, the transverse section of the light-changing slice 72 is wavy, and the transverse section of the light-changing slice 72 is divided into an edge segment 721 and a central segment 722. When the adjusting plate 6 is straightened, the tangent of the central segment 722 is parallel to the straight line where the adjusting plate 6 is located directly below.
[0054] When the adjusting plate 6 is straightened, at this time 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 adjusting plate 6 is located directly below. Therefore, the light emitted from the bulb 32 can be irradiated in parallel light, and thus a relatively uniform light distribution range can be provided, realizing clear illumination in the nearby area, and at the same time avoiding the problem of discomfort caused by the over-bright light to the user.
[0055] As Figure 8 shown, the adjusting plate 6 is provided with an inclined surface 61, and the included 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, at this time the light will flow out through the gap between the adjusting plates 6, and the reflection by the inclined surface 61 can make the light scattered along the adjusting plate 6 diffuse in all directions. Therefore, 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 have been shown and described above. At the same time, the present invention is not limited by the above embodiments. Without departing from the effects and scope of the present invention, various changes and improvements will occur to the present invention, and these changes and improvements all fall within the scope of the present invention claimed. The scope of the present invention claimed is defined by the appended claims and their equivalents.
