Description

Technical Field

[0001] The present invention relates to the technical field of headlights, and in particular to a headlight. Background Art

[0002] A headlamp is a lighting device that is worn on the user's head and used for lighting. It does not need to be held by the user and is a lighting tool that can free the hands. It is widely used in mining operations, maintenance operations, and outdoor sports such as mine operations and outdoor orienteering. Existing headlamps have multiple lighting modes such as spotlight, floodlight, and flash. Users can adjust the lighting mode of the headlamp to apply it to different work scenarios.

[0003] The headlamps in the prior art have the following technical problems during use: in daily use, the end of the headlamp with the glass sheet (or lampshade) is generally fixed. If dust, dirt or insect corpses accumulate on the glass sheet (or lampshade), it may affect the transmittance of light, and it is necessary to always have some wet wipes for wiping, which reduces the practicality. When the user reads paper books in a dark environment, the power of the headlamp can be reduced so that the light shining on the book will not be too dazzling, but it will also reduce the brightness around the user, thereby affecting the user's judgment of the surrounding environment. When the surrounding brightness is guaranteed, the light reflected on the paper book is too dazzling, causing the user to feel dazzled. When using the existing headlamp, the brightness around the user and the brightness on the paper book cannot meet the user's needs at the same time, further reducing the practicality of the headlamp. Summary of the invention

[0004] The present invention provides a headlamp. The use of the headlamp can simultaneously meet the brightness requirements of the user's surroundings and the brightness requirements on paper books, thereby increasing practicality. After the headlamp is used, the end of the headlamp with the lampshade can be cleaned and maintained to ensure the light transmittance of the headlamp when in use.

[0005] The technical solution of the present invention is as follows: A headlamp comprises a headlamp base, a light-emitting tube for emitting light, a buckle plate, and a plurality of flexible light strips connected between the headlamp base and the buckle plate, wherein the light-emitting tube is connected to a side of the headlamp base away from the buckle plate; A protective tube is rotatably connected to the side of the headlamp base away from the buckle plate, a receiving tube is threadedly connected to the protective tube, a positioning block is fixedly connected to the side of the receiving tube away from the protective tube, and a flip module for flipping the light beam direction of the light tube is connected to the inner side of the positioning block; The upper side of the positioning block is rotatably connected with a floodlight mirror which cooperates with the flip module to diffuse the light beam of the light tube; A cleaning module for cleaning and maintaining the light-emitting tube lampshade is detachably fixedly connected to the protective tube; A micro motor for driving the protective tube to rotate is fixedly connected inside the headlamp base, and a driving shaft of the micro motor is fixedly connected to the protective tube.

[0006] Furthermore, the flip module includes a placement plate, the placement plate is rotatably connected to the positioning block, the placement plate is rotatably connected to the limiting block, and the light-emitting tube is detachably fixedly connected to the limiting block.

[0007] Furthermore, a damping module for increasing the rotational friction force is provided between the positioning block and the floodlight and between the placement plate and the limiting block.

[0008] Furthermore, the cleaning module includes a wash plate, which is detachably fixedly connected to the protective tube, a cleaning sponge is fixedly connected to the wash plate on the side facing the receiving tube, and the wash plate and the cleaning sponge are coaxially provided with through holes.

[0009] Furthermore, the protective tube is provided with two weight-reducing grooves, the receiving tube is provided with a first empty groove and two second empty grooves, and the width of the first empty groove is greater than the width of the placement plate.

[0010] Furthermore, a plurality of locking grooves are provided on both sides of the locking block.

[0011] Furthermore, the floodlight mirror includes a first light mirror, and second light mirrors are fixedly connected to both sides of the first light mirror, and the angle between each of the second light mirrors and the first light mirror is greater than 0 degree.

[0012] Furthermore, a partition is fixedly connected inside the headlamp base, and the partition is fixedly connected to the micro motor at one side away from the receiving tube. A wireless charging module for charging the tail end of the light tube is fixedly connected to the partition.

[0013] The beneficial effects of the present invention are: The floodlight mirror radiates the light beam after the light tube is flipped upward by the flip module, ensuring that the brightness around the user can warn the user and the pedestrians around, while the brightness irradiated on the paper books will not be too high, reducing the stimulation of the light beam on the paper books to the user's eyes, so that the user can meet the brightness requirements of the user's surroundings and the brightness requirements on the paper books at the same time, increasing practicality. The cleaning module protects one end of the light tube lampshade, and when the protective tube and the receiving tube rotate and reset, the dirt attached to the surface of the lampshade can be cleaned synchronously, ensuring the light transmittance of the light tube lampshade, and then ensuring the brightness of the light tube, thereby increasing the service life of the light tube components.

DETAILED DESCRIPTION

[0017] The following will be combined with the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention. Example

[0018] like Figure 1 to Figure 6 As shown, this embodiment provides a headlamp, comprising a headlamp base 11, a light-emitting tube 12 for emitting light, a snap plate 13, and a plurality of flexible light strips 14 connected between the headlamp base 11 and the snap plate 13, wherein the light-emitting tube 12 is connected to a side of the headlamp base 11 away from the snap plate 13; The side of the headlamp base 11 away from the buckle plate 13 is rotatably connected to the protective tube 21, the protective tube 21 is threadedly connected to the receiving tube 22, the side of the receiving tube 22 away from the protective tube 21 is fixedly connected to the positioning block 23, and the flip module for flipping the light beam direction of the light tube 12 is connected to the inner side of the positioning block 23; The floodlight mirror 24 that cooperates with the flip module to diffuse the light beam of the light tube 12 is rotatably connected to the upper side of the positioning block 23; The floodlight mirror 24 floodlights the light beam after the light tube 12 is flipped upward by the flip module, ensuring that the brightness around the user can warn the user and the pedestrians around, while making the brightness irradiated on the paper book not too high, reducing the stimulation of the light beam on the paper book to the user's eyes, so that the user can meet the brightness requirements of the user's surroundings and the brightness requirements on the paper book at the same time, thereby increasing practicality; A cleaning module for cleaning and maintaining the lampshade of the light tube 12 is detachably fixedly connected to the protective tube 21; The cleaning module protects one end of the lampshade of the light tube 12. When the protective tube 21 and the receiving tube 22 rotate and reset, the dirt attached to the surface of the lampshade can be cleaned synchronously, thereby ensuring the light transmittance of the lampshade of the light tube 12, and then ensuring the brightness of the light tube 12, thereby improving the service life of the components of the light tube 12. The micro motor 28 for driving the protective tube 21 to rotate is fixedly connected in the headlamp base 11 , and the driving shaft of the micro motor 28 is fixedly connected to the protective tube 21 .

[0019] like Figure 3 and Figure 5 As shown, the flip module includes a placement plate 25, the placement plate 25 is rotatably connected to the positioning block 23, the limit block 26 is rotatably connected to the placement plate 25, the light-emitting tube 12 is detachably fixedly connected to the limit block 26, and the limit block 26 can be made into a clamping ring separated up and down. When the light-emitting tube 12 is damaged, it can be quickly removed from the limit block 26, which is convenient for users to carry out simple repairs and replacements and reduce maintenance costs.

[0020] like Figure 3 and Figure 5~Figure 6 As shown, damping modules for increasing rotational friction are provided between the positioning block 23 and the floodlight mirror 24 and between the mounting plate 25 and the limit block 26, so that the user can manually adjust the angle between the floodlight mirror 24 and the positioning block 23 or between the mounting plate 25 and the limit block 26 at will, which is convenient for the user to adjust.

[0021] like Figure 3 and Figure 4 As shown, the cleaning module includes a plug-in cleaning plate 31, which is detachably fixedly connected to the protective tube 21, and the plug-in cleaning plate 31 is fixedly connected to the cleaning sponge 32 on the side facing the receiving tube 22. When the light-emitting tube 12 rotates one circle, the end with the lampshade moves toward the cleaning sponge 32. Through the rotation of the protective tube 21 and the receiving tube 22, the lampshade and the cleaning sponge 32 can be rotated and squeezed synchronously, so that the dirt attached to the lampshade can be removed, thereby ensuring the light transmittance of the light-emitting tube 12 when it is used next time, ensuring the stability of the brightness of the light-emitting tube 12, and improving the service life of the headlamp components. Two through holes 33 are coaxially opened on the plug-in cleaning plate 31 and the cleaning sponge 32 respectively.

[0022] like Figure 4~Figure 6 As shown, two weight-reducing grooves 211 are both provided on the protective tube 21, and the first empty groove 221 and the two second empty grooves 222 are both provided on the receiving tube 22, so as to ensure that the protective tube 21 and the receiving tube 22 can rotate relative to each other. At the same time, by reducing the weight-reducing grooves 211 and the second empty grooves 222, the masses of the protective tube 21 and the receiving tube 22 themselves are reduced, thereby reducing the overall weight of the headlamp, thereby ensuring the comfort of the user when carrying it. The width of the first empty groove 221 is greater than the width of the mounting plate 25.

[0023] like Figure 4~Figure 6 As shown, a plurality of locking grooves 231 are respectively provided on both sides of the locking block 23 for increasing the friction between the user's fingers and the locking block 23 so that when the protective tube 21 rotates, the locking block 23 fixedly connected to the receiving tube 22 can move more stably.

[0024] like Figure 4~Figure 6 As shown, the floodlight 24 includes a first light mirror 241, and two second light mirrors 242 are respectively fixedly connected on both sides of the first light mirror 241, and the angles between each second light mirror 242 and the first light mirror 241 are greater than 0 degrees. When the light beam passes through the floodlight 24, it will be reflected to the surroundings by the floodlight 24, thereby dispersing the brightness of the light beam. When the user observes the paper book, the brightness will not be too bright. At the same time, the light beam irradiated on the surrounding will illuminate the surroundings of the user, further reducing the stimulation of the light beam reflected from the paper book to the user's eyes. After the surrounding brightness is increased, the user's ability to judge the surrounding environmental factors can be improved, and it also serves as a warning to other pedestrians around, thereby ensuring the safety of the user.

[0025] like Figure 1~Figure 3 As shown, the partition 27 is fixedly connected in the headlamp base 11, and the partition 27 is fixedly connected to the micro motor 28 on the side away from the receiving tube 22. The wireless charging module used to charge the tail end of the light tube 12 is fixedly connected to the partition 27. The partition 27 protects the micro motor 28 to prevent external dust from affecting the operation of the micro motor 28.

[0026] The principle of this embodiment is: When the user is using it normally: The light tube 12 is triggered to emit light by a button on the headlamp base 11. The brightness and light-emitting mode of the light tube 12 are adjusted according to the brightness of the surrounding light. The headlamp base 11 charges the tail end of the light tube 12 through a wireless charging module. A separate battery is provided in the light tube 12 so that the light tube 12 can be used normally after being separated from the wireless charging module. When users view paper books in a dark environment: One hand holds the side of the positioning block 23, and increases the clamping force of the finger on the positioning block 23 through the positioning groove 231, and then the other hand activates another button on the headlamp base 11 to trigger the micro motor 28 to work, thereby driving the protective tube 21 to rotate. Under the limiting effect of the finger on the positioning block 23, the distance between the threaded protective tube 21 and the receiving tube 22 will gradually increase. When the flipping of the placement plate 25 does not interfere with the protective tube 21, the micro motor 28 will stop working, and then the placement plate 25 is flipped by hand to make the light beam direction of the light tube 12 face upward, and then the light mode of the light tube 12 is adjusted to the floodlight mode, and then the light beam is further dispersed through the floodlight mirror 24 to ensure that there is enough light around the user, and at the same time reduce the stimulation of the reflected light on the paper book to the user's eyes, so that the user can read the book more comfortably; When the user needs to maintain the light tube 12: First, the light tube 12 is set to face the floodlight 24 through the flip assembly, and then the light tube 12 is flipped 180 degrees so that the end of the light tube 12 with the lampshade faces downward, and then the flip assembly is reset so that the end of the light tube 12 with the lampshade faces the headlamp base 11, and then the positioning block 23 is held and the micro motor 28 is started to reverse and reset, and the end of the light tube 12 with the lampshade will be spirally squeezed against the cleaning sponge 33, so that the dirt on the surface of the lampshade is synchronously scrubbed, and after the reset is completed, the protective tube 21 can protect the light tube 12 set in the protective tube 21 and protect the light tube 12. Example

[0027] In this embodiment, the clip plate 13 and the flexible light strip 14 are modified on the basis of the first embodiment.

[0028] like Figure 1 to Figure 6 As shown, reflective material is applied on the buckle plate 13 and the flexible light strip 14. When the light beams of surrounding pedestrians shine on the buckle plate 13 and the flexible light strip 14, they will reflect light, thereby further serving as a warning to the surrounding pedestrians. Example

[0029] In this embodiment, the headlamp base 11 is modified on the basis of the first embodiment.

[0030] like Figure 1 to Figure 6 As shown, the headlamp base 11 includes an electric control housing and a linkage housing. A PLC board for controlling the operation of various components is arranged in the electric control housing. The linkage housing is hinged to the electric control housing so that the linkage housing can be flipped downward around the hinged position with the electric control housing.

[0031] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
