DETAILED DESCRIPTION

[0016] In combination Figures 1 to 10 As shown in the drawings, the embodiment provides a tool lamp, which comprises a main body module 1 and a lamp body module 2 rotatably connected to the main body module 1, and the lamp body module 2 is configured to be switched between a first state and a second state. When the lamp body module 2 is in the first state, the lamp body module 2 is accommodated on the main body module 1, at which time a control module is triggered to make a second lighting device provided on the lamp body module 2 closed. When the lamp body module 2 is switched to the second state, a preset angle is formed between the lamp body module 2 and the main body module 1, and the control module can be triggered immediately after the lamp body module 2 is separated from the first state to make the second lighting device open and remain. A force-storable elastic component 3 is arranged between the lamp body module 2 and the main body module 1, and the elastic component 3 is adapted to store force when the lamp body module 2 is in the first state to provide a driving force for automatically switching the lamp body module 2 from the first state to the second state.

[0017] It should be noted that in the embodiment, the lamp body module 2 can trigger the control module through an induction module to control the second lighting device to open when the lamp body module 2 is separated from the first state, and the second lighting device remains open during the process of switching from the first state to the second state and the process of switching from the second state to the first state because the induction module is not triggered again. When the induction module senses that the lamp body module 2 is switched to the first state, the control circuit controls the second lighting device to close. Thus, the embodiment can control the opening and closing of the second lighting device according to the sensing signal of the induction module according to the position of the lamp body module 2 sensed by the induction module.

[0018] The main body module 1 is a shell structure that carries internal components and provides external protection, which can be made of high-strength engineering plastic by injection molding. The lamp body module 2 refers to a movable part that integrates lighting elements, which can be implemented by an aluminum alloy frame combined with a light-transmitting cover, and is used to provide lighting functions. The elastic component 3 refers to a force storage element that can store mechanical potential energy, which can be implemented by a torsional spring, and is used to accumulate elastic potential energy in the storage state and drive the lamp body to expand when released. When the lamp body module 2 is folded onto the main body module 1, the elastic component 3 deforms to store mechanical energy; it should be noted that the folding of the lamp body module 2 onto the main body module 1 can be to store the lamp body module 2 inside the main body module, or to store the lamp body module 2 on the upper and lower sides or the four peripheral sides of the main body module 1, and in the storage state, it can be completely overlapped, or it can be arranged at a preset angle, side by side, etc. When the locking mechanism is manually released, the elastic component 3 releases the stored energy to push the lamp body module 2 to rotate around the rotating shaft to expand until it reaches the preset angle to trigger the limiting mechanism. When folding in reverse, the resistance of the elastic component 3 needs to be overcome until the lamp body module 2 switches to the first state and is locked by the locking mechanism. Through the above technical solution, the application realizes the one-handed quick expansion and storage function of the lighting lamp, and sets up an automatic on-off mechanism to avoid energy waste caused by misoperation.

[0019] In this embodiment, the elastic component 3 can be a torsional spring; the main body module 1 is provided with a rotating hole 11; the lamp body module 2 is provided with a rotating shaft component 4 adapted to be inserted into the rotating hole 11, and the rotating shaft component 4 is formed with a torsional spring limiting groove 111 for connecting one connecting arm of the torsional spring; a limiting piece 5 with an insertion hole 51 is arranged between the rotating shaft component 4 and the main body module 1, and the end of the rotating shaft component 4 is adapted to be inserted into the insertion hole 51, so that the limiting piece 5 covers the opening side of the torsional spring limiting groove 111, thereby limiting one connecting arm of the torsional spring in the torsional spring limiting groove 111, and at the same time enabling the rotating shaft component 4 to remain stable when rotating.

[0020] The main body module includes a shell, and the limiting piece 5 is locked on the shell of the main body module 1 by a screw, and the shell extends inwardly to form a cylinder 103, the cylinder 103 is hollow to form the rotating hole 11, the torsional spring is adapted to be sleeved outside the cylinder 103, and a gap 12 is formed outside the cylinder 103 to provide a torsional spring deformation space, and the other connecting arm of the torsional spring is connected in a groove of the shell of the main body module 1.

[0021] The rotating shaft component 4 can be made of metal or high-strength plastic, and the end thereof is inserted into the rotating hole 11 and is limited in the main body module 1 by the snap spring 6, so as to prevent the rotating shaft component 4 from being pulled out. In a preferred embodiment, the rotating shaft component 4 is integrally formed on the shell, so as to improve the service life of the rotating structure. The torsion spring limiting groove 111 refers to two grooves formed on the end of the rotating shaft component 4, which are used for limiting a connecting arm of the torsion spring, and the connecting arm of the torsion spring is bent and placed in the groove.

[0022] When the lamp body module 2 is received in the main body module 1, the torsion spring is elastically deformed and accumulates energy due to the rotation of the rotating shaft component 4; after the lamp body module 2 is released by unlocking, the torsion spring releases the accumulated elastic potential energy, drives the rotating shaft component 4 to drive the lamp body module 2 to automatically pop out. The gap 12 formed on the outer side of the cylinder 103 allows the torsion spring to radially displace during deformation, so as to avoid structural jamming due to insufficient space. After the limiting piece 5 is locked by a screw, the rotating shaft component 4 can be prevented from being axially deviated during rotation, so as to ensure the stable connection between the lamp body module 2 and the main body module 1, and to ensure that the connecting arm of the torsion spring is limited in the rotating shaft component 4. In combination Figure 10 As shown in the embodiment, along the axial extension direction of the rotating shaft component 4, the limiting piece 5 is arranged above the snap spring 6, and a limiting protrusion 52 is arranged on the side of the limiting piece 5 facing the snap spring 6, which is adapted to be inserted into the variable gap formed on the snap spring 6, so as to limit the snap spring 6 from rotating with the axial component 4, and to improve the stability and smoothness of the entire rotating mechanism.

[0023] In a preferred embodiment, a wear-resistant piece 7 is arranged at the rotating connection surface 14 between the main body module 1 and the lamp body module 2, which can be made of POM material, so as to avoid wear between the main body module 1 and the lamp body module 2 during relative rotation, thereby affecting the service life of the product. The POM material has low friction coefficient and high wear resistance, and can withstand mechanical wear caused by repeated rotation. The rotating connection surface 14 refers to the contact area between the main body module 1 and the lamp body module 2 for relative rotation, and the metal or plastic components in direct contact are isolated by the wear-resistant piece 7 during rotation. The wear-resistant piece 7 can be provided with two anti-rotation ribs on the rotating connection surface 14, and the wear-resistant piece 7 is provided with anti-rotation grooves matched with the anti-rotation ribs, and the rotation stop block 15 also penetrates the wear-resistant piece 7, and three-point limiting is formed by the rotation stop block 15 and the two anti-rotation ribs, so as to prevent the wear-resistant piece 7 from rotating.

[0024] In the embodiment, the rotating stop block 15 is protruded on the rotating connection surface 14 of the main body module 1, and the arc-shaped groove 21 matched with the rotating stop block 15 is formed on the lamp body module 2, and the rotating stop block 15 is adapted to slide along the arc-shaped groove 21 and limit the rotation angle of the lamp body module 2 through the arc-shaped groove 21.

[0025] The rotation stopper 15 can be mounted on the main body module or integrally formed with the shell of the main body module, and the material thereof includes plastic or metal. The rotation stopper made of metal can improve the mechanical life. When the lamp body module 2 rotates from 0 degree to a preset angle, the movement angle of the rotation stopper 15 in the arc-shaped groove 21 is limited. The rotation stopper 15 is a protruding structure arranged on the rotation connecting surface 14 of the main body module 1, and is used to produce physical obstruction when the lamp body module 2 rotates. The arc-shaped groove 21 is a curved recess structure formed on the surface of the shell of the lamp body module 2, and is used to accommodate the rotation stopper 15 and guide the sliding track thereof. The length and the curvature of the groove body limit the movement range of the rotation stopper 15, so as to accurately control the maximum rotation angle of the lamp body module 2. In the embodiment, the angle is set to 180 degrees.

[0026] In the preferred embodiment, the rotation stopper 15 is made of metal and integrally formed with the main body module 1 by the potting process. The whole structure is formed by wrapping the metal part with molten plastic, which enhances the bonding strength. The metal stopper formed by the potting process not only eliminates the assembly error, but also improves the overall structural strength through the combination of materials and processes, which helps to improve the product life. In another embodiment, the rotation stopper 15 can also be integrally formed with the shell of the main body module 1 by the injection molding process. It should be noted that the setting mode and shape of the rotation stopper 15 can also be implemented in different schemes according to the needs, including but not limited to this.

[0027] In the embodiment, the outer wall of the rotating shaft component 4 is provided with a sealing groove 112 for mounting the sealing ring 8 and a clamping groove 113 for mounting the clamping spring 6, and the rotating shaft component 4 is limited in the main body module 1 by the clamping spring 6. The sealing ring 8 can be made of silica gel or rubber material, and forms an elastic sealing interface between the rotating shaft component 4 and the main body module 1. It can form a seal with the inner wall of the cylinder 103 to prevent water or dust from entering the lamp body. The clamping spring 6 can be a standard E-shaped clamping spring or a C-shaped clamping spring. After being elastically deformed and clamped into the clamping groove 113, it restores to its original state to form a mechanical obstruction. Through the cooperation of the clamping spring 6 and the clamping groove 113, the axial displacement or disengagement of the rotating shaft component 4 during rotation is prevented, and the stability of the rotating mechanism is ensured. During installation, the sealing ring 8 is first pressed into the sealing groove 112, and then the rotating shaft component 4 is inserted into the rotating hole 11 of the main body module 1. When the rotating shaft component 4 is completely inserted, the clamping spring 6 is installed in the clamping groove 113 to form axial limiting, and the locking limiting piece 5 is locked to limit the rotation of the clamping spring 6. The clamping spring 6 is located above the end of the cylinder 103, and is used to limit the rotating shaft component 4 from being pulled out of the rotating hole 11.

[0028] In the preferred embodiment, the locking mechanism comprises a magnetic component arranged on the main body module 1, which is adapted to attract the corresponding metal or magnetic part when the lamp body module 2 is in the first state, so as to keep the lamp body module 2 in the first state. The magnetic component can be implemented by a neodymium iron boron magnet or a permanent magnet, which is used to overcome the restoring force of the elastic component, so that the lamp body module 2 will not automatically expand in the storage state. The lamp body module 2 can be provided with a metal or magnetic part at a corresponding position to match the magnetic component on the main body module 1, so as to lock the lamp body module 2 by the magnetic component when the lamp body module 2 is in the storage state. The locking belongs to flexible locking, and the lamp body module 2 can be unlocked by overcoming the magnetic force by external force.

[0029] In the preferred embodiment, the surface of the main body module 1 facing the lamp body module 2 is further provided with a positioning column 16, and the surface of the lamp body module 2 facing the main body module 1 is provided with a positioning groove 22 adapted to cooperate with the positioning column 16, so as to assist the locking mechanism to keep the lamp body module 2 in the first state; the positioning column 16 can be implemented by a spherical protruding structure, which forms a physical clamping with the spherical positioning groove 22 on the surface of the lamp body module 2, so as to keep the lamp body module 2 in the storage state.

[0030] In the preferred embodiment, the magnetic component comprises a first magnetic block group 17 and a second magnetic block group 18, the first magnetic block group 17 is arranged on one side of the main body module 1, and the second magnetic block group 18 is arranged on the other side adjacent to the first magnetic block group 17. The two adjacent magnetic block groups form a composite magnetic field through space vector superposition, which effectively improves the constraint force on the lamp body module 2. When the lamp body module 2 is folded into the main body module 1, the two groups of magnetic forces form a 90° angle in space, which improves the positioning reliability while maintaining a compact structure. It should be noted that a single magnetic part can also have a limiting effect, but the preferred embodiment uses two magnetic block groups arranged at 90°, which has a better limiting effect on the lamp body module 2 than a single magnetic part.

[0031] In the embodiment, a control module is further included, which comprises a control circuit and a sensing module. The sensing module comprises a third magnetic block group 23 and a fourth magnetic block group 24 arranged on the lamp body module 2. The S pole of the third magnetic block group 23 faces the main body module 1, and the N pole of the fourth magnetic block group 24 faces the main body module 1, i.e. they are placed in positive and negative directions. The control module further comprises a first Hall sensor 19 and a second Hall sensor 110 arranged on the main body module 1 and connected to the control circuit. The first Hall sensor 19 is arranged in a positive direction to respond to the third magnetic block group 23, and the second Hall sensor 110 is arranged in a negative direction to respond to the fourth magnetic block group 24, i.e. they are also placed in positive and negative directions.

[0032] When the third magnetic block group 23 and the fourth magnetic block group 24 change position, the first Hall sensor 19 and the second Hall sensor 110 are adapted to determine the true trigger state according to the timing trigger state of the third magnetic block group 23 and the fourth magnetic block group 24, and the control circuit controls the opening and closing of the second lighting device in the lamp body module 2 according to the true trigger state. Two single-pole trigger Hall sensors are used, and the magnetic pole recognition direction is opposite by using the positive and negative installation methods, so as to realize the control principle of double-path complementary detection and anti-mis-triggering. Specifically: The first Hall sensor 19 is arranged in a forward direction, that is, a Hall element that is triggered only in response to an N-pole magnetic field, for example, a single-pole Hall switch can be used, and the sensing surface is arranged to face the third magnetic block group 23. The single-pole Hall sensor works based on the Hall effect inside: when the current flows in the chip, the vertical magnetic field acts to generate a Hall voltage, and the direction is determined by the magnetic induction line direction. The sensor outputs a conduction signal only when the magnetic induction intensity in a specific direction exceeds the action threshold. For example, an AH49E type Hall switch can be used, but it is not limited to this. When the Hall is installed in a forward direction, the N-pole of the magnet faces the front of the Hall piece, the magnetic induction line enters the surface of the chip, and the direction forms a forward Hall voltage with the internal current, which meets the trigger condition, so it is triggered by the N-pole; The second Hall sensor 110 arranged in a reverse direction is a Hall element of the same type installed by physically rotating 180 degrees, which can be realized by reversing the same type of Hall switch to make it respond only to S-pole magnetic field triggering. When the single-pole Hall is installed in a reverse direction (turned over 180°), the direction of the magnetic induction line of the magnet is reversed relative to the chip, and the polarity of the Hall voltage is reversed. At this time, the S-pole needs to be close to produce the same direction of Hall voltage as the original, so as to realize S-pole triggering.

[0033] When the lamp body module 2 moves relative to the main body module 1, the position change of the third magnetic block group 23 and the fourth magnetic block group 24 will cause the magnetic field distribution to change. Since the first Hall sensor 19 arranged in a forward direction only responds to the N-pole magnetic field of the third magnetic block group 23, and the second Hall sensor 110 arranged in a reverse direction only responds to the S-pole magnetic field of the fourth magnetic block group 24, when the magnet moves or changes position, the outputs of the two sensors form complementary logic, and the control circuit determines the true trigger state by state combination or timing, effectively avoiding the misoperation of a single sensor caused by external magnetic interference.

[0034] The control circuit collects the output signals of the two Hall sensors in real time, and determines that it is a real trigger signal when detecting that the two Hall sensors produce a state combination that conforms to the preset timing logic. For example, during the unfolding process of the lamp body module 2 switching from the first state to the second state, the third magnetic block group 23 and the fourth magnetic block group 24 trigger the first Hall sensor 19 and the second Hall sensor 110, respectively, at the same time, so that the control circuit determines that the lamp body module 2 is out of the first state, and then triggers the opening and closing of the second lighting device in the lamp body module 2; when the lamp body module switches from the second state to the first state, the third magnetic block group 23 and the fourth magnetic block group 24 trigger the first Hall sensor 19 and the second Hall sensor 110, respectively, at the same time again, so that the control circuit controls the second lighting device to be closed; in other embodiments, the order of the positions of the third magnetic block group 23 and the fourth magnetic block group 24 can also be set, for example, the first Hall sensor 19 and the second Hall sensor 110 can be triggered in sequence to control the opening and closing of the lighting device. Through the timing trigger logic, the setting direction of the two Hall sensors, and the design of the orientations of the third magnetic block group 23 and the fourth magnetic block group 24, the opening and closing of the second lighting device are cooperatively controlled, which can effectively resist interference; in particular, it is not affected by the magnetic components for realizing the locking mechanism on the lamp body module 2 and external magnetic components.

[0035] The scheme forms a complementary detection mechanism by arranging bipolar magnetic groups and installing Hall sensors in forward and reverse directions. The control circuit can effectively distinguish between real actions and interference signals through logical judgment. Only when two complementary Hall sensors sense the magnetic induction changes of N-S two magnetic components, the power switch of the lighting device will be triggered. Compared with the single sensor scheme that requires a complex filter circuit or shielding structure, the scheme realizes higher anti-interference ability at the same cost, effectively solves the problem of false triggering caused by external magnetic field interference in traditional magnetic induction control, and ensures that the lighting device state switching is triggered only when the lamp body module 2 actually moves. The scheme maintains the simplicity of the mechanical structure while improving the working reliability of the lighting tool in a complex electromagnetic environment, avoiding lighting abnormalities or energy waste caused by false triggering. The control circuit described in the embodiment is an existing circuit that can realize the opening and closing control of the lighting device, which includes a control board that can receive the sensing signals of the sensing module and control the opening and closing of the lighting device according to the sensing signals.

[0036] It should be noted that in some embodiments, the two Hall sensors can also be arranged on the lamp body module 2, and the third magnetic component 19 and the fourth magnetic component 110 are arranged on the main body module.

[0037] In the embodiment, the first lighting device 101 is arranged on the main body module 1, and the second lighting device 201 is arranged on the lamp body module 2; the first lighting device 101 is adapted to be triggered on and off by the switch device 102 on the main body module 1; and the second lighting device 201 is adapted to be triggered on and off by the control circuit. The first lighting device 101 refers to a light-emitting unit arranged at a fixed position of the main body module 1, which can adopt a lamp group arranged at the end of the shell and directly controlled by a physical button to turn on and off the circuit. The second lighting device 201 refers to a lighting unit integrated in the rotatable lamp body module 2, which can adopt, for example, a high-brightness COB light source matched with a lens module to realize, and is automatically activated after the lamp body is detected to be unfolded by a Hall sensor, and only works when the lamp body is unfolded, effectively reducing the power loss caused by false triggering. The control circuit is a logic control module carried in the lamp body module 2 or the main body module 1, which can be realized by using a microcontroller matched with a double-channel complementary Hall detection circuit, and the real triggering state is determined by recognizing the position combination of the magnet and the time sequence action.

[0038] When the lamp body module 2 is in the closed state, the first lighting device 101 can be independently turned on by the physical switch on the side, and at this time, the second lighting device 201 is in the power-off state because the lamp body is not unfolded. When the lamp body module 2 is separated from the first state, the control circuit detects the change of the magnetic pole state through the double Hall sensors from the moment of separation to the unfolding to the working angle, and automatically activates the second lighting device 201. The two groups of lighting devices can adopt independent power supply lines, the first group of lines is fixedly connected in the main body module 1, and the second group of lines can be wired along the rotating shaft component 4 and connected by using a flexible flat cable, effectively avoiding the repeated bending of the wire during the rotation. In the storage state, the rotating action of the lamp body module 2 only controls the power supply circuit of the second lighting device 201, and the first lighting device 101 can still work independently. The two groups of lighting devices can independently operate according to the use scene, reducing the mechanical wear and improving the operation convenience.

[0039] It should be noted that in the embodiment, the power supply assembly can be arranged in the main body module 1, and the lines can also pass through the inside of the rotating shaft component 4, reducing the winding effect of the lines caused by the rotation of the rotating shaft component 4 and improving the service life of the lamp.

[0040] In the above embodiment, the elastic driving of the torsional spring is combined with the adsorption positioning of the magnet to form a unique “automatic pop-up + manual reset” mechanism. When the lamp body needs to be unfolded for use, the initial locking force is overcome by applying an external force, and the elastic potential energy stored in the torsional spring is immediately released, automatically rotating the lamp body to the 180-degree working position; after use, the magnet adsorption + mechanical positioning ensures stable fixation.
