Description

Technical Field

[0001] The present invention belongs to the technical field of lighting adjustment, and specifically relates to a flashlight with adjustable lighting direction. Background Art

[0002] The emergence of flashlights has improved the portability of lighting devices and expanded the usage scenarios. With the development of lighting technology, a spotlighting technology has emerged. This technology reduces the scattering of light sources, enables the light emitted by the light-emitting body to be emitted in a fixed direction, and greatly improves the utilization rate of light sources.

[0003] A patent with the publication number CN104421642A discloses a flashlight with bendable lighting, which includes a barrel body, an internal circuit of the flashlight, and a lighting head. The lighting head can be snap-connected to the barrel body through a buckle, and the lighting head is fixedly connected to the barrel body through a universal joint tube hidden inside the barrel body by bending. The present invention overcomes the problem that traditional flashlights cannot turn for lighting when lighting in a certain direction in a specific narrow space. When using the bendable lighting function of the present invention, loosen the connection buckle between the lighting head and the barrel body, pull the lighting head away from the barrel body, and the bendable lighting function of the flashlight lighting head can be realized by the deformation and support of the universal joint tube connected between the lighting head and the barrel body for 360° free rotation and bending.

[0004] In the current prior art, traditional flashlights are generally straight-barrel type. When lighting in a certain direction in a specific narrow space, the flashlight cannot turn for lighting because it is straight-barrel type. When an employee needs to operate with both hands, one hand needs to hold the flashlight, and the other hand cannot operate. If the flashlight is directly attached to the belt or upper garment, the light of the straight-barrel flashlight can only shine upward and cannot directly irradiate the position that needs to be operated.

[0005] Therefore, the present invention provides a flashlight with adjustable lighting direction. Summary of the Invention

[0006] In order to make up for the deficiencies of the prior art and solve at least one technical problem proposed in the background art.

[0007] The technical solution adopted by the present invention to solve its technical problems is as follows: A flashlight with adjustable lighting direction according to the present invention includes a flashlight and a protective sleeve movably sleeved on the outer surface of the flashlight. A silicone anti-slip ring is fixedly connected to the outer surface of the flashlight at the top edge position, and an elastic hanging arm is fixedly connected to the outer surface of the flashlight at the top edge position of the silicone anti-slip ring. A rotating shaft is provided at the top end of the flashlight, and a lighting barrel is provided on the outer surface of the rotating shaft.

[0008] Preferably, a cylindrical cavity is provided inside the bottom layer of the protective sleeve. A limiting block is fixedly connected to the inner side wall of the bottom of the cylindrical cavity, and grooves are formed on the outer surface around the limiting block.

[0009] Preferably, the flashlight includes:

[0010] A sound monitoring module for acquiring sound information;

[0011] A driving motor connected to the rotating shaft (115);

[0012] A control module connected to the sound monitoring module and the driving motor, analyzing the direction information of the sound source according to the sound information, and then instructing the driving motor to control the rotation of the rotating shaft (115) according to the direction information, thereby driving the lighting cylinder (116) to illuminate in the direction of the sound source.

[0013] Preferably, the flashlight includes:

[0014] A camera device connected to the control module for acquiring image information;

[0015] A remote communication module connected to the control module for receiving a remote control signal to start the operation of the camera device.

[0016] Preferably, an elastic push wire is fixedly connected to the inner side wall of the groove, and an elastic wire two is fixedly connected to the inner side wall of the top of the cylindrical cavity. The other end of the elastic wire two is fixedly connected to a heightening support strip, and a support backing plate is fixedly connected to the bottom surface of the heightening support strip.

[0017] Preferably, a downward pressure counterweight block movably sleeved on the inner side wall of the limiting block is fixedly connected to the bottom surface of the support backing plate and located at the middle position. A limiting convex block is provided at one end of the support backing plate, and a triangular barb is provided at the bottom edge position of the limiting convex block at one end of the support backing plate. A notch is provided between the limiting convex block and the triangular barb.

[0018] Preferably, a strip-shaped card slot is formed on the outer surface of the protective sleeve. An inlaid limiting card slot is formed on the inner side wall of the strip-shaped card slot. An elastic wire one is fixedly connected to the inner side wall of the top of the strip-shaped card slot, and the other end of the elastic wire one is movably lapped on the outer surface of the top of the limiting roller.

[0019] Preferably, the outer surface of the limiting roller is movably lapped on the inner wall surface of the recessed limiting card slot. A swinging hollow arm is fixedly connected to the outer surface of the bottom of the limiting roller. The outer surface of the swinging hollow arm is movably sleeved on the inner wall surface of the strip-shaped card slot. An in-ward recessed strip-shaped card slot is arranged on the outer surface of one end of the swinging hollow arm.

[0020] Preferably, the outer surface of the triangular barb is movably sleeved on the inner wall surface of the in-ward recessed strip-shaped card slot. An anti-slip head is arranged on the outer surface of one end of the swinging hollow arm and located outside the in-ward recessed strip-shaped card slot. The outer surface of the other end of the elastic pushing wire is movably lapped on the outer surface of the anti-slip head.

[0021] Preferably, a silica gel anti-collision head is arranged on the outer surface of the top end of the lighting lamp tube. A switch is arranged at the top edge position of the flashlight. An anti-collision bottom cover is arranged at the bottom edge position of the flashlight. The outer surfaces of the anti-collision bottom cover and the silica gel anti-slip ring are movably sleeved on the inner wall surface of the protective sleeve.

[0022] The beneficial effects of the present invention are as follows:

[0023] 1. For the flashlight with adjustable lighting direction of the present invention, when the flashlight is needed, the flashlight can be held by hand and placed horizontally for lighting. When carrying goods at night or both hands are needed, the lighting lamp tube can be rotated 180° by using the rotating shaft, so that a 90° angle is formed between the flashlight and the lighting lamp tube. The elastic hanging arm is clamped on the pants belt or the upper pocket, and the silica gel anti-slip ring on the outer surface of the flashlight is used to increase the friction with the clothing. At the same time, the length and weight of the flashlight are used to make the center of gravity of the flashlight always below the elastic hanging arm, so that the flashlight will not swing with the swing of the user during the operation of the user.

[0024] 2. For the flashlight with adjustable lighting direction of the present invention, when the user needs to illuminate a single direction in a large range, the flashlight is clamped into the inside of the protective sleeve, and the friction with the inner wall surface of the protective sleeve is increased through the silica gel anti-slip ring, so that the protective sleeve and the anti-collision bottom cover can be firmly adsorbed together. Through the polygonal shape on the outer surface of the anti-collision bottom cover, when the anti-collision bottom cover is clamped deep into the inside of the protective sleeve, it can be fully clamped with the rectangular inner wall surface of the protective sleeve, so that both ends of the flashlight can be fully clamped and the position of the flashlight can be limited.

[0025] 3. For a flashlight with adjustable lighting direction according to the present invention, when the flashlight is snapped into the inner part of the protective sleeve, hold the lighting tube and strike the protective sleeve against the ground. While generating the impact, lift and lower the lighting tube. At this time, after the bottom surface of the protective sleeve generates an impact, the pressing weight will carry the supporting backing plate and the elevated supporting bar to move vertically upward, and elastically squeeze the second elastic wire. When the limiting convex block moves upward, the triangular barb at one end of the limiting convex block will disengage from the inner recessed strip-shaped card slot. When one end of the swinging hollow arm is no longer restricted by the triangular barb, at this time, the elastic pushing wire will give an elastic impact to one end of the swinging hollow arm, causing the swinging hollow arm to spread out in all directions. Just at this time, the lighting tube is in a descending state. When the protective sleeve fits back on the ground, the swinging hollow arm of this swing will overlap at the peripheral position of the protective sleeve, thereby increasing the contact range and area with the ground and enhancing the stability effect of the protective sleeve;

[0026] 4. For a flashlight with adjustable lighting direction according to the present invention, when the swinging hollow arm spreads out in all directions under the dragging of the elastic pushing wire, it cooperates with the first elastic wire in the strip-shaped card slot to push the limiting roller, and makes the limiting roller move downward in the inner recessed limiting card slot. At this time, the swinging hollow arm will move downward to the bottom end of the protective sleeve. The swinging hollow arm of this swing will overlap at the peripheral position of the protective sleeve, thereby increasing the contact range and area with the ground, making the swinging hollow arm wrap around the protective sleeve in a fan shape. When the flashlight shakes, the first elastic wire can elastically buffer the extrusion of the swinging hollow arm. BRIEF DESCRIPTION OF THE DRAWINGS

Detailed implementation manners

[0039] In order to make the technical means, creative features, achieved purposes and functions of the present invention easy to understand, the present invention will be further described below in conjunction with specific implementation manners.

[0040] As Figures 1 to 9 shown, a flashlight with adjustable lighting direction according to an embodiment of the present invention includes a flashlight 11 and a protective sleeve 12 movably sleeved on the outer surface of the flashlight 11. A silicone anti-slip ring 113 is fixedly connected to the outer surface of the flashlight 11 and located at the top edge position. An elastic hanging arm 112 is fixedly connected to the outer surface of the flashlight 11 and located at the top edge position of the silicone anti-slip ring 113. A rotating shaft 115 is provided at the top end of the flashlight 11. A lighting barrel 116 is provided on the outer surface of the rotating shaft 115. A silicone anti-collision head 117 is provided on the outer surface of the top end of the lighting barrel 116. A switch 114 is provided at the top edge position of the flashlight 11. An anti-collision bottom cover 111 is provided at the bottom edge position of the flashlight 11. The outer surfaces of the anti-collision bottom cover 111 and the silicone anti-slip ring 113 are movably sleeved on the inner wall surface of the protective sleeve 12.

[0041] When the flashlight 11 is needed, the user can hold the flashlight 11 and place it horizontally for illumination. When carrying goods at night or when both hands are needed, the illuminating lamp tube 116 is rotated 180° by using the rotating shaft 115, so that a 90° angle is formed between the flashlight 11 and the illuminating lamp tube 116. Then, the elastic hanging arm 112 is clamped on the pants belt or the upper pocket, and the silicone anti-slip ring 113 on the outer surface of the flashlight 11 is used to increase the friction with the clothing. At the same time, the length and weight of the flashlight 11 are used to keep the center of gravity of the flashlight 11 always below the elastic hanging arm 112, so that the flashlight 11 will not swing with the user's movement during operation.

[0042] As Figures 3 to 9 shown, a cylindrical cavity 121 is provided inside the bottom layer of the protective sleeve 12. A limiting block 122 is fixedly connected to the inner bottom wall surface of the cylindrical cavity 121. Grooves are provided on the outer surface around the limiting block 122, and elastic pushing wires 123 are fixedly connected to the inner wall surfaces of the grooves. A second elastic wire 129 is fixedly connected to the inner top wall surface of the cylindrical cavity 121. The other end of the second elastic wire 129 is fixedly connected to a raised support bar 128. A support backing plate 125 is fixedly connected to the bottom surface of the raised support bar 128. A downward pressing weight block 124 that is movably sleeved on the inner wall surface of the limiting block 122 is fixedly connected to the middle position of the bottom surface of the support backing plate 125. A limiting convex block 126 is provided at one end of the support backing plate 125. A triangular barb 127 is provided at the bottom edge position of the limiting convex block 126 at one end of the support backing plate 125, and a notch is provided between the limiting convex block 126 and the triangular barb 127.

[0043] When the user needs to illuminate a large area in a single direction, the flashlight 11 is clamped into the protective sleeve 12, and the friction with the inner wall surface of the protective sleeve 12 is increased through the silicone anti-slip ring 113, so that the protective sleeve 12 and the anti-collision bottom cover 111 can be firmly adsorbed together. Through the polygonal shape on the outer surface of the anti-collision bottom cover 111, when the anti-collision bottom cover 111 is clamped deep into the protective sleeve 12, it can be fully clamped with the rectangular inner wall surface of the protective sleeve 12, so that both ends of the flashlight 11 can be fully clamped, and the position of the flashlight 11 can be limited.

[0044] When the flashlight 11 is snapped into the interior of the protective sleeve 12, hold the lighting barrel 116 and strike the protective sleeve 12 against the ground. While generating the impact, lift and lower the lighting barrel 116. At this time, after the bottom surface of the protective sleeve 12 generates an impact, the pressing weight 124 will carry the support backing plate 125 and the elevation support bar 128 and move vertically upward, and elastically squeeze the second elastic wire 129. When the limiting bump 126 moves upward, the triangular barb 127 at one end of the limiting bump 126 will disengage from the interior of the recessed strip-shaped card slot a6. When one end of the swinging hollow arm a5 is no longer restricted by the triangular barb 127, at this time, the elastic push wire 123 will elastically impact one end of the swinging hollow arm a5, causing the swinging hollow arm a5 to spread out in all directions. Just at this time, the lighting barrel 116 is in a descending state. When the protective sleeve 12 is reattached to the ground, the swinging hollow arm a5 of this swing will overlap at the peripheral position of the protective sleeve 12, thereby increasing the contact range and area with the ground and enhancing the stability effect of the protective sleeve 12.

[0045] As Figures 4 to 9 shown, a strip-shaped card slot a1 is provided on the outer surface of the protective sleeve 12. An inlaid limiting card slot a2 is provided on the inner side wall surface of the strip-shaped card slot a1. A first elastic wire a3 is fixedly connected to the top inner side wall surface of the strip-shaped card slot a1. The other end of the first elastic wire a3 is movably overlapped on the top outer surface of the limiting roller a4. The outer surface of the limiting roller a4 is movably overlapped on the inner side wall surface of the inlaid limiting card slot a2. A swinging hollow arm a5 is fixedly connected to the bottom outer surface of the limiting roller a4. The outer surface of the swinging hollow arm a5 is movably sleeved on the inner side wall surface of the strip-shaped card slot a1. An inlaid strip-shaped card slot a6 is provided on the outer surface of one end of the swinging hollow arm a5. The outer surface of the triangular barb 127 is movably sleeved on the inner side wall surface of the inlaid strip-shaped card slot a6. An anti-slip head a7 is provided on the outer surface of one end of the swinging hollow arm a5 and located on the outer surface of the inlaid strip-shaped card slot a6. The outer surface of the other end of the elastic push wire 123 is movably overlapped on the outer surface of the anti-slip head a7.

[0046] When the swinging hollow arm a5 spreads out in all directions under the dragging of the elastic push wire 123, it cooperates with the first elastic wire a3 inside the strip-shaped card slot a1 to push the limiting roller a4 and causes the limiting roller a4 to move downward inside the inlaid limiting card slot a2. At this time, the swinging hollow arm a5 will move downward to the bottom end of the protective sleeve 12. The swinging hollow arm a5 of this swing will overlap at the peripheral position of the protective sleeve 12, thereby increasing the contact range and area with the ground and causing the swinging hollow arm a5 to wrap around the protective sleeve 12 in a fan shape. When the flashlight 11 shakes, the first elastic wire a3 can elastically buffer the extrusion of the swinging hollow arm a5;

[0047] When the protective sleeve 12 is stored later, the swing hollow arm a5 is rebounded and squeezed, and one end of the swing hollow arm a5 is clamped into the inside of the strip slot a1, and one end of the triangular hook 127 is clamped into the inside of the sunken strip slot a6, and the elastic push wire 123 is compressed.

[0048] Working principle: When the flashlight 11 is needed, the flashlight 11 can be held in the hand and placed horizontally for lighting. When carrying goods at night or when both hands are needed, the rotating shaft 115 is used to rotate the lighting tube 116 180°, so that a 90° angle is formed between the flashlight 11 and the lighting tube 116. The elastic hanging arm 112 is clamped on the belt of pants or the pocket of a coat, and the silicone anti-skid ring 113 on the outer surface of the flashlight 11 is used to increase the friction between the flashlight 11 and the clothes. At the same time, the length and weight of the flashlight 11 are used to make the center of gravity of the flashlight 11 always located below the elastic hanging arm 112, so that the flashlight 11 will not swing with the swing of the user when the user is working.

[0049] When the user needs to illuminate a large area in a single direction, the flashlight 11 is inserted into the inside of the protective sleeve 12, and the friction between the flashlight 11 and the inner wall of the protective sleeve 12 is increased by the silicone anti-slip ring 113, so that the protective sleeve 12 and the anti-collision bottom cover 111 can be firmly adsorbed together, and the polygonal shape of the outer surface of the anti-collision bottom cover 111 allows the anti-collision bottom cover 111 to be fully inserted into the deep inside of the protective sleeve 12, so that the two ends of the flashlight 11 can be fully inserted, and the position of the flashlight 11 is limited;

[0050] When the flashlight 11 is inserted into the protective sleeve 12, the lighting tube 116 is held and the protective sleeve 12 is hit against the ground. At the same time, the lighting tube 116 is lifted and lowered. At this time, after the bottom surface of the protective sleeve 12 is hit, the downward pressing counterweight 124 will carry the supporting pad 125 and the padding support bar 128 to move vertically upward and elastically squeeze the elastic wire 129. When the limiting protrusion 126 moves upward, the triangular barb 127 on one end of the limiting protrusion 126 will move out from the recessed bar slot a6. When one end of the swinging hollow arm a5 is no longer bound by the triangular hook 127, the elastic force pushing wire 123 is used to elastically impact one end of the swinging hollow arm a5, so that the swinging hollow arm a5 spreads out to the surroundings. At this time, the lighting tube 116 is in a descending state. When the protective sleeve 12 is re-attached to the ground, the swinging hollow arm a5 will overlap the peripheral position of the protective sleeve 12, thereby increasing the contact range and area with the ground, and increasing the stability of the protective sleeve 12.

[0051] As Figure 10 shown, in an alternative embodiment, the flashlight includes:

[0052] a sound monitoring module for acquiring sound information;

[0053] a drive motor connected to the rotating shaft (115);

[0054] a control module connected to the sound monitoring module and the drive motor, analyzing the sound information to obtain the direction information of the sound source, and then instructing the drive motor to control the rotation of the rotating shaft (115) according to the direction information, thereby driving the lighting barrel (116) to illuminate in the direction of the sound source.

[0055] Among them, the sound monitoring module captures sound signals in the environment through a microphone array or a directional microphone. Through built-in sound pickup devices such as microphones, sound information of different frequencies and intensities is converted into electrical signals, providing basic data for subsequent processing. For example, in an outdoor adventure scenario, it can sensitively capture various sounds such as animal calls and shouts from companions. After receiving the sound information from the sound monitoring module, the control module analyzes the sound using complex algorithms. By calculating parameters such as the time difference and intensity difference between different sensors (if there is an array composed of multiple microphones), the direction information of the sound source is accurately determined. For example, when the sound comes from the left, the left microphone will receive the sound signal earlier than the right microphone, and the signal intensity may be stronger. The control module can judge the sound direction by analyzing these differences. According to the analyzed direction information, the control module quickly generates corresponding control instructions and sends them to the drive motor to command it to act according to the requirements, realizing the automatic adjustment of the lighting direction of the flashlight. The drive motor is the power source for the flashlight to achieve automatic turning, similar to the engine of a car. After receiving the instruction from the control module, it converts electrical energy into mechanical energy to generate a rotational torque. This torque is transmitted to the rotating shaft (115) through a mechanical transmission mechanism (such as a gear set, etc.), driving the rotating shaft to rotate. The rotating shaft (115) serves as a transmission component, connecting the drive motor and the lighting barrel (116). It smoothly and accurately transmits the rotational motion generated by the drive motor to the lighting barrel (116), ensuring that the lighting barrel can rotate in a predetermined direction and angle.

[0056] In the embodiment of the present invention, the flashlight realizes the function of automatically adjusting the lighting direction according to the sound source through the coordinated work of the sound monitoring module, the control module, the drive motor, the rotating shaft, and the lighting barrel.

[0057] In an alternative embodiment of the present invention, the flashlight includes:

[0058] A camera device, which is connected to the control module and is used to acquire image information;

[0059] A remote communication module, which is connected to the control module and is used to receive remote control signals to start the operation of the camera device.

[0060] The camera device serves as the "visual organ" of the flashlight. It is responsible for capturing image information of the surrounding environment. It usually consists of components such as a lens and an image sensor (such as CMOS or CCD). The lens focuses light onto the image sensor, and the image sensor converts the optical signal into an electrical signal, and then generates a digital image. For example, in an outdoor adventure scenario, it can take pictures of the surrounding terrain, plants and animals, etc., providing intuitive video materials for users to record the exploration process. The remote communication module is a key component for the flashlight to communicate with external remote devices (such as mobile phones, tablets, remote monitoring centers, etc.). It supports specific communication protocols (such as Wi-Fi, Bluetooth, 4G / 5G, etc.) and can receive control signals from remote devices. For example, when the user sends an instruction to start the camera device through the mobile phone APP from a distance, the remote communication module will receive the signal and transmit it to the control module.

[0061] For example, during an expedition, a team member got separated from the team and went missing. The team member carried this flashlight, which had been paired with the team leader's mobile phone before departure and was connected to the search and rescue center's temporary emergency communication network. After receiving the alarm, the search and rescue center quickly took action. Considering that the missing person might not be able to call for help actively, the commander sent an instruction to start the camera device to take pictures to the flashlight through the emergency network. The remote communication module of the flashlight received the instruction, and after parsing and verification, it transmitted the instruction to the control module. The control module immediately started the camera device and set shooting parameters such as high-definition resolution and high frame rate. The camera device scanned the surrounding environment by rotating 360 degrees, took a picture every 30 degrees of rotation, and recorded the timestamp and positioning information. If it detected changes in sound or light, it would automatically adjust the shooting direction and focal length. For example, when it heard a faint cry for help, it would quickly turn to the sound source for key shooting. This flashlight has stable transmission of instructions and images, the camera device accurately takes pictures of key clues, and the positioning function provides a general direction, greatly improving the search and rescue efficiency.

Those skilled in the art should understand that the present invention is not limited by the above embodiments. What is described in the above embodiments and the specification only illustrates the principles of the present invention.
