Description

Technical Field

[0001] The invention relates to the field of machinery, and in particular to a laser headlamp, a swing structure and a swing electric fan. Background Art

[0002] Laser headlights are called the "reasonable next step" after LED headlights. They are more energy-efficient and fuel-efficient. This type of laser headlight is not the dazzling laser in the movies. It is not even dazzling at all. The principle is that the blue light of the laser light-emitting diode will penetrate the fluorescent phosphor material in the headlight unit and convert it into a diffuse white light, which is brighter and more friendly to the eyes.

[0003] The application with publication number CN108626682A discloses a vehicle laser headlamp, and specifically discloses: it includes a laser light source, an optical module, a heat sink module, a structural module and a driving module. The light emitted by the laser light source is reflected or transmitted by the optical module to form a laser headlamp illumination light pattern; the heat sink module provides heat dissipation for the laser light source; the structural module combines the modules together; the driving module provides a stable output for the laser light source. However, in this device, the fan is fixedly installed and can only blow air at a fixed angle, so that the heat dissipation of the laser light source is not uniform, and the local temperature in the decorative frame is too high, which seriously affects the heat dissipation of the laser light source and reduces its service life. At the same time, the user cannot grasp the temperature inside the decorative frame in time, which makes it very easy for the laser light source to overheat for a long time, and even causes the laser light source to burn out. Summary of the invention

[0004] In order to solve the problem that the fan in the laser headlamp in the prior art can only be installed at a fixed angle, blow air, and the heat dissipation is not uniform, the present invention proposes a laser headlamp, a swing structure and a swing fan to solve the above technical problems. The technical solution of the present invention is as follows:

[0005] A swing structure comprises: a frame; a driving device, which is arranged on the frame; a connecting rod assembly, one end of which is connected to the driving device, and under the driving action of the driving device, the free end of the connecting rod assembly swings back and forth; a mounting block, a limiting piece is arranged on the mounting block, and a track groove for the limiting piece to extend into is opened on the frame, and the mounting block swings under the driving action of the free end of the connecting rod assembly.

[0006] By setting a driving device to drive the mounting block to swing through the connecting rod assembly, the reciprocating swing of the mounting block can be achieved without setting a control circuit in the entire swing structure. If an electric fan is set on the mounting block, the reciprocating swing of the electric fan can be achieved, thereby improving the uniformity of the fan's heat dissipation.

[0007] Furthermore, the connecting rod assembly includes: a rotating connecting rod, under the driving action of the driving device, at least one end of the rotating connecting rod performs a circular motion; a swing connecting rod, the swing connecting rod is hinged to one end of the rotating connecting rod that performs a circular motion, the swing center of the swing connecting rod is connected to a support rod, the support rod movably supports the swing connecting rod, and the other end of the swing connecting rod drives the mounting block to swing.

[0008] Furthermore, the support rod is slidably disposed on the frame through a sliding block, and one end of the support rod is rotatably disposed in the sliding block.

[0009] By properly arranging the connecting rod assembly, the swing connecting rod is driven by the rotating connecting rod and supported by the supporting rod to make reciprocating swings, thereby driving the mounting block to make reciprocating swings.

[0010] Furthermore, the swing link and the mounting block are connected via a slider slot structure, a slider is hingedly connected to one end of the swing link close to the mounting block, a slot is provided on the mounting block, and the slider can be slidably extended into the slot.

[0011] The mounting block cooperates with the track groove through the limiting piece, and the sliding block cooperates with the sliding groove to limit the position, so as to realize the reciprocating swing of the mounting block.

[0012] A swinging electric fan comprises a swinging structure and an electric fan, wherein the electric fan is arranged on a mounting block. By arranging the electric fan on the mounting block, the mounting block drives the electric fan to swing back and forth, thereby increasing the heat dissipation area and improving the heat dissipation efficiency.

[0013] A laser headlamp comprises a lamp and an oscillating electric fan, wherein the lamp is arranged on the frame and the oscillating electric fan works toward the lamp. By arranging the oscillating electric fan to work toward the lamp, it is avoided that the lamp is blown only from one angle, resulting in poor heat dissipation effect.

[0014] Furthermore, the lamp includes a light-emitting element and an optical component, the light-emitting element is fixed on the frame through a fixing rod; the optical component includes a reflector for controlling light.

[0015] Furthermore, it also includes an alarm component, which includes a box body and an alarm. A sliding plate that can slide along the box body is provided in the box body. The heat conductor conducts the heat in the frame body to the box body to generate a pressure difference in the cavity on both sides of the sliding plate. The pressure difference drives the sliding plate to slide and trigger the alarm.

[0016] The pressure difference on both sides of the sliding plate is caused by heat conduction to push the sliding plate to move, thereby triggering the alarm. It can sensitively sense the temperature changes inside the laser headlamp and trigger the alarm according to the temperature changes. There is no need to set up electronic components such as sensors and controllers, and the structure is stable and controllable.

[0017] Furthermore, a driving member is arranged on the surface of the sliding plate away from the heat-conducting member, a first conductive block is arranged on the top of the driving member, a second conductive block is arranged on the box body, and the driving member drives the first conductive block and the second conductive block to contact and trigger the alarm.

[0019] Based on the above structure, the technical effects that can be achieved by the present invention are:

[0020] 1. The laser headlamp, swing structure and swing electric fan of the present invention drive the mounting block to swing by providing a driving device through a connecting rod assembly. The entire swing structure does not need to be provided with a control circuit. The reciprocating swing of the mounting block can be achieved only through mechanical linkage. The electric fan is provided on the mounting block to achieve the reciprocating swing of the electric fan, thereby preventing the electric fan from working in only one direction and improving the uniformity of the heat dissipation of the electric fan.

[0021] 2. The laser headlamp, swing structure and swing electric fan of the present invention are reasonably arranged with a connecting rod assembly including a rotating connecting rod, a swing connecting rod and a supporting rod. The rotating connecting rod drives one end of the swing connecting rod to make a circular remote movement. The supporting rod flexibly supports the swing connecting rod at the swing center so that the other end of the swing connecting rod makes a reciprocating swing. The other end of the swing connecting rod flexibly drives the mounting block through the slider slot structure. The mounting block can realize reciprocating swing under the action of the swing connecting rod and the limiter. The fan installed on the mounting block can also realize multi-angle operation to improve the heat dissipation rate.

[0022] 3. The laser headlamp of the present invention is also provided with an alarm component, which causes a pressure difference on both sides of the sliding plate through heat conduction to push the sliding plate to move, thereby triggering an alarm. It can sensitively sense the temperature change inside the frame and trigger the alarm according to the temperature change.

DETAILED DESCRIPTION

[0029] The content of the present invention will be further described below in conjunction with the accompanying drawings.

[0030] like Figure 1-5 As shown, this embodiment provides a swing structure, including a frame 1, a driving device 2, a connecting rod assembly 3 and a mounting block 4, wherein the driving device 2 is arranged on the frame 1, and the driving device 2 drives the mounting block 4 to swing through the connecting rod assembly 3. Preferably, the driving device 2 is a motor, and under the driving action of the driving device 2, the free end of the connecting rod assembly 3 drives the mounting block 4 to swing back and forth.

[0031] The connecting rod assembly 3 includes a rotating connecting rod 31, a swing connecting rod 32 and a supporting rod 33. Under the driving action of the driving device 2, at least one end of the rotating connecting rod 31 performs a circular motion. In this embodiment, the rotating connecting rod 31 is L-shaped. The rotating connecting rod 31 can be integrally formed or formed by two rods connected vertically. In addition, the rotating connecting rod 31 can also be set to other shapes, as long as at least one end thereof deviates from the driving axis and performs a circular motion.

[0032] One end of the rotating link 31 that performs circular motion is hinged to the swing link 32, and one end of the swing link 32 that is connected to the rotating link 31 performs circular motion under the drive of the rotating link 31. The swing center of the swing link 32 is also connected to the support rod 33. Under the drive of the rotating link 31 and the support of the support rod 33, the other end of the swing link 32 moves along a fixed motion trajectory. Preferably, the swing center of the swing link 32 is located in the middle of the swing link 32. One end of the support rod 33 is fixedly connected to the swing center of the swing link 32, and the other end of the support rod 33 is movably arranged on the frame 1. Specifically, the other end of the support rod 33 is slidably arranged on the frame 1 through a sliding block 34, and the other end of the support rod 33 is connected to the sliding block 34. A sliding groove 11 corresponding to the sliding block 34 is arranged on the frame 1, and the sliding block 34 can slide along the sliding groove 11. Preferably, the sliding groove 11 extends horizontally on the inner wall of the frame 1. Furthermore, the other end of the support rod 33 is rotatably disposed in the sliding block 34, and the support rod 33 can rotate relative to the sliding block 34. Specifically, a stepped circular hole is opened at one end of the sliding block 34 toward the support rod 33, and the aperture inside the stepped circular hole is larger than the aperture outside. A circular anti-slip protrusion 331 is provided at the end of the support rod 33. The anti-slip protrusion 331 cooperates with the gap between the stepped circular hole and the support rod 33. On the one hand, the support rod 33 can be prevented from detaching from the sliding block 34, and on the other hand, the support rod 33 can rotate in the sliding block 34.

[0033] The swing link 32 and the mounting block 4 are connected by a slider slide groove structure, and a slider 321 is hinged at one end of the swing link 32 close to the mounting block 4. A slide groove 42 is provided on the mounting block 4, and the slider 321 can slide into the slide groove 42. Specifically, limiting protrusions 322 extend from both sides of the slider 321, and the slide groove 42 partially expands outward, and the limiting protrusion 322 slides along the slide groove 42 to prevent the slider 321 from escaping from the slide groove 42.

[0034] One end of the mounting block 4 is movably connected to the connecting rod assembly 3 through a slider slot structure, and a limiter 41 is extended from the other end of the mounting block 4. A track slot 12 corresponding to the limiter 41 is provided on the frame 1, and the outer end of the limiter 41 extends into the track slot 12 and can move along the track slot 12. Preferably, the limiter 41 and its extension line do not overlap with the slot 42, and the mounting block 4 can swing stably under the action of the limiter 41 and the slider 321 without shaking.

[0035] Based on the above structure, the working principle of the swing structure of this embodiment is that when the driving device 2 is working, it drives the rotating connecting rod 31 to perform circular motion, and the swing connecting rod 32 moves along the fixed track under the action of the rotating connecting rod 31 and the support rod 33, and the mounting block 4 performs a swinging motion under the joint action of the limit member 41 and the sliding 321 on the swing connecting rod 32.

[0036] The present embodiment further provides a swinging electric fan, comprising the above-mentioned swinging structure and an electric fan 5 , wherein the electric fan 5 is arranged on the mounting block 4 and swings accordingly.

[0037] This embodiment also provides a laser headlamp, including an oscillating fan and a lamp, the lamp is arranged on a frame 1, and the oscillating fan works toward the lamp. Preferably, the frame 1 is in a sealed or nearly sealed box shape, and the oscillating fan and the lamp are both arranged in the frame 1.

[0038] The lamp includes a light-emitting element 6 and an optical component. The light-emitting element 6 is fixedly arranged on the frame 1 through a fixing rod 61; the optical component includes a reflector for controlling light, specifically including a first reflector 71 and a second reflector 72. The first reflector 71 is arranged on the fixing rod 61, and its reflective surface faces the light-emitting element 6. The second reflector 72 is installed in the frame 1 through a bracket 721. Its reflective surface faces the light-emitting element 6. The emission direction of the light emitted by the light-emitting element 6 can be adjusted by setting the first reflector 71 and the second reflector 72. Preferably, the light-emitting element 6 is a laser light source, and the laser light source signal can be selected but not limited to H55H533L53. The swing fan works toward the light-emitting element 6.

[0039] It also includes an alarm component 8, which is arranged on one side of the frame 1. The alarm component 8 includes a box 81, in which a sliding plate 82 is slidably arranged. The sliding plate 82 divides the box 81 into two cavities, one of which can receive the heat transferred from the frame 1, and the other cavity is provided with a trigger structure for triggering the alarm 89. The heat transferred from the frame 1 causes a pressure difference between the two cavities, pushing the sliding plate 82 to slide in the box 81, thereby triggering the alarm 89. Specifically, a slide groove 83 is opened in the box 81, and the sliding plate 82 slides in the box 81 along the direction of the slide groove 83. The heat conductive member 9 conducts the heat in the frame 1 to a cavity of the box 81. Specifically, one end of the heat conductive member 9 extends into the frame 1, and the other end of the heat conductive member 9 extends into the box 81 to conduct heat. A trigger structure is provided in another cavity. Specifically, a driving member 84 is provided on the surface of the sliding plate 82 away from the heat-conducting member 9. The driving member 84 is connected with a first conductive block 851. The inner wall of the box 81 is provided with a second conductive block 861. The sliding plate 82 drives the first conductive block 851 on the driving member 84 to move toward the second conductive block 861. When the first conductive block 851 and the second conductive block 861 contact, the alarm 89 is triggered. Further, a limit block 86 for limiting the range of motion of the driving member 84 is also provided in the box 81. The limit block 86 is a cavity structure with one end open, and the opening faces the driving member 84. The top of the driving member 84 is fixedly connected to a limit plate 85. The limit plate 85 is located inside the limit block 86. The outer diameter of the limit plate 85 is larger than the aperture of the opening, so as to limit the range of motion of the driving member 84. The first conductive block 851 is provided on the limit plate 85, and the second limit block 861 is provided on the inner bottom surface of the limit block 86. Furthermore, an elastic reset member 87 is provided, one end of which is connected to the limit plate 85 , and the other end of which is connected to the open end of the limit block 86 , so as to provide a reset force to the limit plate 85 .

[0040] A battery 88 and an alarm 89 are fixedly installed on the top of the box 81. The first conductive block 851, the second conductive block 861, the battery 88 and the alarm 89 are electrically connected in sequence. When the first conductive block 851 and the second conductive block 861 are in contact, the circuit is connected, and the alarm 89 sends an alarm signal to indicate that the temperature inside the frame 1 of the laser headlamp is too high. Preferably, the alarm 89 can be selected from but not limited to an alarm bell.

[0041] Based on the above structure, the working principle of the laser headlamp of this embodiment is as follows: the light-emitting body 6 emits light and releases heat in the frame 1, and the swinging fan swings toward the light-emitting body 6 to work. As the working time of the light-emitting body 6 increases, the temperature in the frame 1 gradually increases, and the heat-conducting member 9 conducts the high temperature in the frame 1 to the box 81, so that a pressure difference is formed in the cavities on both sides of the sliding plate 82. The air pressure in the cavity connected to the heat-conducting member 9 is greater than the air pressure in the other cavity, thereby pushing the sliding plate 82 to move. The sliding plate 82 drives the first conductive block 851 to move toward the second conductive block 861 until contact is made. When contact is made, the circuit where the alarm 89 is located is connected, and the alarm 89 sends an alarm signal to remind the staff that the temperature in the frame 1 is too high.

[0042] The embodiments of the present invention are described in detail above with reference to the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge scope of ordinary technicians in this field without departing from the purpose of the present invention.
