Description

Technical Field

[0001] This invention relates to the field of escape tool technology, and in particular to a safety hammer and its control system. Background Technology

[0002] In emergency escape scenarios such as vehicle accidents and fires, safety hammers are core tools for breaking windows and escaping danger, and their performance directly affects personal safety in emergency situations. As a mainstream window-breaking tool, electric safety hammers have high efficiency and success rate in breaking windows. However, most electric safety hammers are instant-triggered structures without a pre-charge structure before operation. This results in low efficiency when facing continuous operation and high-precision, rapid impact conditions. Furthermore, there is a risk that accidental triggering can also cause an impact, and the high-speed impact head can easily cause hand injuries, crushing, or other safety accidents. Summary of the Invention

[0003] The main objective of this invention is to propose a safety hammer and its control system, which aims to solve the problem that existing safety hammers, due to their instant-trigger structure, cannot balance work efficiency and operational safety.

[0004] To achieve the above objectives, the present invention provides a safety hammer, comprising: The casing has a front end; A hammering assembly is disposed on the housing and an energy storage element is connected between the two. The hammering assembly is movably disposed and can extend and retract from the front end. The drive assembly can be engaged and disengaged to drive the hammering assembly. When engaged, it pushes the hammering assembly inward, causing the energy storage element to store energy. When disengaged, it releases the constraint on the hammering assembly, the energy storage element resets, and drives the hammering assembly to extend. A trigger module, disposed in the housing, includes an energy storage trigger component and a hammer impact trigger component. The energy storage trigger component is used to trigger the energy storage element to stop storing energy, and the hammer impact trigger component is used to trigger the hammer impact component to operate. The energy storage trigger component includes an energy storage sensor, and the hammer impact trigger component includes a hammer impact sensor. When the drive component drives the hammer impact component to retract to the first energy storage position, the energy storage sensor is triggered. The trigger signal of the energy storage sensor serves as at least one of the signals to stop the drive component and keep the hammer impact component and the energy storage element in their current positions. When the front end presses against the surface to be hammered, the hammer impact sensor is triggered. The trigger signal of the hammer impact sensor serves as at least one of the signals to separate the drive component from the hammer impact component.

[0005] Optionally, the safety hammer is further provided with a signal processing unit, which is used to collect and identify the on / off status of the branch where the energy storage sensor is located and the branch where the hammer impact sensor is located, respectively. When the energy storage sensor is triggered, the corresponding branch is disconnected, and the branch where the hammer impact sensor is located remains disconnected, the signal processing unit can output a stop command to stop the drive component. When the hammer impact sensor is triggered and the corresponding branch is turned on, while the branch where the energy storage sensor is located remains disconnected, the signal processing unit can output a power-on command to enable the drive component to continue operating or at least to separate from the hammer impact component.

[0006] Optionally, the triggering module further includes an energy storage triggering component, which includes an energy storage excitation unit and an energy storage sensing unit. One of the energy storage excitation unit and the energy storage sensing unit is disposed corresponding to the hammer impact component and / or the energy storage element, and the other is disposed in the housing. When the hammer impact component is retracted to the first energy storage position, the energy storage excitation unit and the energy storage sensing unit are coupled and triggered.

[0007] Optionally, the energy storage sensing unit has an elastically pressable energy storage contact; the energy storage excitation unit is configured as a pressing part, and is configured corresponding to and linked with the hammering assembly and / or the energy storage element. When the hammering assembly retracts to the first energy storage position, the energy storage excitation unit moves to press the energy storage contact so that the two are coupled and triggered.

[0008] Optionally, the hammer triggering component further includes a hammer excitation unit, which is coupled to trigger the hammer excitation unit and the hammer sensing unit when the front end is pressed against the surface to be hammered.

[0009] Optionally, the hammering sensing unit has a hammering contact that can be elastically pressed; the hammering excitation unit is movably disposed at the front end, and when the front end presses against the surface to be hammered, the hammering excitation unit is pressed inward from the front end and presses against the hammering contact, so that the two are coupled and triggered.

[0010] Optionally, the energy storage sensing unit is configured as an energy storage signal receiving unit or an energy storage pressure on / off unit; and / or, The hammer impact sensor is configured as a hammer impact signal receiving unit or a hammer impact pressure on / off unit.

[0011] Optionally, the safety hammer further includes a user-operated operation sensor, which is disposed in the housing. When both the hammer impact sensor and the operation sensor are triggered, the drive assembly can drive the hammer impact assembly to move to separate from the hammer impact assembly. When the operation sensor is triggered but the hammer impact sensor is not triggered, the drive assembly can drive the hammer impact assembly to retract and the energy storage element to store energy. When the energy storage element stores energy to a preset state, the energy storage sensor is triggered.

[0012] Optionally, the safety hammer further includes a power supply unit and a lighting unit. The lighting unit is electrically connected to the power supply unit, and the power supply unit can supply power to the lighting unit. The lighting unit is located at the front end and is electrically connected to the work sensing unit. The direction of the illumination light from the lighting unit is parallel to the extension direction of the hammer impact assembly.

[0013] Optionally, the operation sensing unit includes an operation pressure on / off unit and a trigger, the trigger being movably disposed in the housing, and the trigger at least partially protruding from the outer wall of the housing for user pressing operation; The working pressure switching unit is located inside the housing, and its working contact is configured corresponding to the trigger, so that when the user presses the trigger, the trigger can press against the working contact to trigger conduction.

[0014] Optionally, the branch where the energy storage sensor is located is configured as an independent first electrical branch; the branch where the impact sensor is located is configured as an independent second electrical branch; the first electrical branch and the second electrical branch run in parallel and their ends are connected to form the parallel branch; the output end of the parallel branch is electrically connected in series with the power supply control end of the drive component.

[0015] The present invention also provides a control system for a safety hammer, used to control the aforementioned safety hammer. The control system includes a first electrical circuit and a second electrical circuit connected in parallel. The first electrical circuit includes a power supply unit, a motor, a first start switch, and an energy storage trigger assembly connected in series. The second electrical circuit includes a power supply unit, a second start switch, a hammer-triggered assembly, and the motor connected in series. The motor is used to control the start and stop of the drive assembly of the safety hammer. The first start switch and the second start switch are connected in series, or the first start switch and the second start switch are the same start switch.

[0016] The technical solution provided by this invention has at least the following advantages: The safety hammer provided by this invention includes a housing, a hammering assembly, a drive assembly, and a triggering module. The triggering module includes an energy storage triggering assembly and a hammering triggering assembly. The energy storage triggering assembly is used to trigger the energy storage element to stop storing energy, and the hammering triggering assembly is used to trigger the hammering assembly to operate. When the first energy storage position is reached to trigger the energy storage element to stop storing energy, energy storage is locked. After energy storage is locked, the circuit is in an open state, and accidental pressing of other operation buttons will not trigger hammering. Only when the front end of the housing presses against the surface to be hammered, triggering the hammering triggering assembly, can the drive assembly be unlocked to achieve hammering. Thus, not only can the safety risk of accidental hammering be reduced through the constraint of the hammering triggering module, but also efficient hammering can be achieved by relying on pre-stored energy, thereby balancing work efficiency and operational safety.

[0020] The realization of the objective, functional features and advantages of the present invention will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0021] To further illustrate the technical means and effects of the present invention in achieving its intended purpose, the following detailed description of the specific implementation methods, structures, features, and effects of the present invention, in conjunction with the accompanying drawings and preferred embodiments, is provided below.

[0022] In emergency escape scenarios such as vehicle accidents and fires, safety hammers are core tools for breaking windows and escaping trapped individuals, and their performance directly affects personal safety in emergency situations. As a mainstream window-breaking tool, electric safety hammers have high efficiency and success rates in breaking windows.

[0023] To balance work efficiency and operational safety, the structure of the safety hammer 100 is improved in this invention. The structure of the safety hammer 100 is described in detail below with reference to the accompanying drawings.

[0024] Please see Figures 1 to 4 ,as well as Figure 8 The safety hammer 100 includes a housing 1, a hammering assembly 2, a drive assembly 5, and a trigger module.

[0025] The housing 1 has a front end 141. A hammering assembly 2 is disposed on the housing 1, and an energy storage element is connected between the two. The hammering assembly 2 is movably disposed and can extend and retract from the front end 141. During the reciprocating stroke of the hammering assembly 2, the hammering assembly 2 has a hammering state, in which the hammer head 21 of the hammering assembly 2 extends out of the housing 1 from the front end 141. The hammering assembly 2 also has an energy storage state, in which the hammer head 21 of the hammering assembly 2 retracts into the housing 1 from the front end 141.

[0026] It should be noted that, in this embodiment, the forward and backward direction is defined by the movement direction of the hammering component 2. The hammering component 2 thrusts forward to strike, and retracts backward into the housing. The energy storage element is an elastic element, including but not limited to an elastic pad or a spring.

[0027] The drive assembly 5 can disengage and engage to drive the hammer impact assembly 2. When the drive assembly 5 is engaged with the hammer impact assembly 2, it can push the hammer impact assembly 2 inward, compressing the energy storage element and storing energy, thus putting the hammer impact assembly 2 into an energy storage state. When the drive assembly 5 is disengaged from the hammer impact assembly 2, it can release the constraint on the hammer impact assembly 2, reset the energy storage element, and drive the hammer impact assembly 2 to extend, thus putting the hammer impact assembly 2 into a hammering state.

[0028] The trigger module is located in the housing 1. The trigger module includes an energy storage trigger component 81 and a hammer impact trigger component 91. The energy storage trigger component 81 is used to trigger the energy storage element to stop storing energy, and the hammer impact trigger component 91 is used to trigger the hammer impact component 2 to work. The energy storage trigger component 81 includes an energy storage sensor 812, and the hammer impact trigger component 91 includes a hammer impact sensor 912. When the drive component 5 drives the hammer impact component 2 to retract to the first energy storage position, the energy storage sensor 812 is triggered. The trigger signal of the energy storage sensor 812 serves as at least one of the signals to stop the drive component 5 and keep the hammer impact component 2 and the energy storage element in their current positions. When the front end presses against the surface to be hammered, the hammer impact sensor 912 is triggered. The trigger signal of the hammer impact sensor 912 serves as at least one of the signals to separate the drive component 5 from the hammer impact component 2.

[0029] In addition to the trigger signal from the energy storage sensor 812, a separate switch or sensor controller can be provided as a signal to stop the drive assembly 5 and maintain the current position of the hammer assembly 2 and the energy storage element. In addition to the trigger signal from the hammer impact sensor 912, a separate switch or sensor controller can also be provided as a signal to separate the drive assembly 5 from the hammer impact assembly 2.

[0030] In this embodiment, the energy storage sensor 812 and the impact sensor 912 are electrically connected in parallel and form a parallel branch, which is electrically connected in series with the drive component 5; the branch where the energy storage sensor 812 is located is a default normally closed circuit, and the branch where the impact sensor 912 is located is a default normally open circuit.

[0031] When the drive assembly 5 drives the hammer assembly 2 to retract to the first energy storage position, the energy storage sensor 812 is triggered. The trigger signal of the energy storage sensor 812 serves as at least one of the signals to stop the drive assembly 5 and keep the hammer assembly 2 and the energy storage element in their current positions.

[0032] In the first stage, the branch containing the energy storage sensor 812 is a normally closed loop by default. When the signal circuit of the safety hammer 100 is turned on, the drive component 5 is activated. When the drive component 5 is combined with the hammer impact component 2, it drives the hammer impact component 2 to retract backward and compress the energy storage element to store energy.

[0033] When the hammer assembly 2 retracts to the preset first energy storage position, the energy storage sensor 812 is triggered, its normally closed branch is disconnected, and at the same time the branch where the hammer sensor 912 is located remains normally open, thereby disconnecting the entire signal circuit. The drive assembly 5 immediately stops working, and the hammer assembly 2 and the energy storage element are stably locked in the first energy storage position.

[0034] Thus, energy storage can be completed in advance at this stage. The user can move or adjust the working posture of the pre-charged and locked safety hammer 100. During this process, the drive component 5 will no longer work, and the hammering component 2 will not perform the hammering action, thereby avoiding safety accidents such as user injury or equipment damage from impact, and thus improving the safety of the safety hammer 100.

[0035] Meanwhile, a pre-energy storage mode is adopted, which compresses the energy storage element in advance to complete energy storage and lock position during the hammering standby stage. When the hammer is triggered, there is no need to spend a lot of time performing the energy compression and storage action. The energy storage element can release energy instantly to drive the hammering component 2 to impact, improve the response speed of the hammering component 2, shorten the interval between hammering triggering and execution, and ensure that the user can break the window and escape at the best time.

[0036] Furthermore, the branch where the energy storage sensor 812 is located is a normally closed loop by default. By triggering the energy storage sensor 812 to cut off the corresponding branch, the drive circuit is automatically cut off and the drive component 5 stops immediately when the energy storage is in place. This ensures accurate energy storage stroke, saves energy storage time, makes the overall response rhythm compact, and improves the operating efficiency of the safety hammer 100.

[0037] When the front end 141 of the housing 1 presses against the surface to be hammered, the hammering sensor 912 is triggered, and the trigger signal of the hammering sensor 912 serves as at least one of the signals to separate the drive assembly 5 from the hammering assembly 2.

[0038] In the second stage, the energy storage element has stored energy and is locked in the first energy storage position. Only when the front end 141 presses against the surface to be hammered will the normally open hammering sensor 912 be triggered and its branch be turned on, while the branch where the energy storage sensor 812 is located remains open. When the entire signal circuit is turned on, the drive assembly 5 continues to move and can move at least until it releases the constraint on the hammering assembly 2 and separates. The energy storage element releases its elastic potential energy and drives the hammering assembly 2 to rush out and complete the hammering operation.

[0039] This design prevents accidental activation, avoiding accidents such as operator injury or equipment damage during handling, accidental contact, or button jamming, thus improving the safety of the safety hammer 100. Furthermore, the triggering condition is clearly defined: the hammer strikes only when the front end 141 is fully pressed down. The control logic is simple, reliable, and has a low failure rate.

[0040] Meanwhile, relying on the conditional triggering mechanism of the front end 141 pressure coupling, each hammer blow is based on the premise that the front end 141 is in contact with the surface to be hammered. This not only reduces the risk of accidental impact caused by the hammer head 21 extending without a target, thus reducing the probability of safety accidents, but also enables the hammer head 21 to act precisely on the surface to be hammered, improving hammering efficiency and blasting success rate.

[0041] In the technical solution of this invention, the normally closed energy storage sensor 812 and the normally open hammer impact sensor 912 are electrically connected in parallel and then electrically connected in series with the drive assembly 5. In the initial state, the energy storage sensor 812 is normally closed, and the signal circuit is open, allowing energy storage to be driven. When the first energy storage position is reached, the signal circuit is automatically disconnected to lock the energy storage.

[0042] After the energy storage is locked, the signal circuit is in an open state. If other operation buttons are accidentally pressed, the hammering cannot be triggered. Only when the front end 141 presses against the surface to be hammered, causing the hammering sensor 912 to close and the signal circuit to be connected, can the drive component 5 be unlocked to realize the hammering.

[0043] In this way, not only can the safety risk of accidental hammering be reduced by the constraint of the trigger module, but also efficient hammering can be achieved by relying on pre-stored energy, thus balancing work efficiency and operational safety.

[0044] Specifically, please refer to Figure 8 The branch where the energy storage sensor 812 is located is configured as an independent first electrical branch; the branch where the hammer impact sensor 912 is located is configured as an independent second electrical branch; the first electrical branch and the second electrical branch run in parallel and their ends are connected to form a parallel branch; the output end of the parallel branch is electrically connected in series with the power supply control end of the drive assembly 5.

[0045] In this embodiment, the energy storage sensor 812 and the hammer impact sensor 912 are respectively set as a first electrical branch and a second electrical branch that are independent of each other. They only converge at the end to form a parallel branch. The wiring and lines of the two branches are not shared, thereby avoiding the problems of electrical crosstalk, false connection, and false disconnection between the two branches; thus improving the stability of the electrical control system.

[0046] Meanwhile, the two branches are physically independent. If the first electrical branch (the branch where the energy storage sensor 812 is located) experiences a disconnection or switch failure, it will only cause the energy storage locking function to fail, and will not cause the second electrical branch (the branch where the hammer impact sensor 912 is located) to be falsely triggered. Similarly, a fault in the second electrical branch will not interfere with the energy storage locking function. In this way, faults can be isolated from each other, resulting in a high fault tolerance capability of the equipment and further improving the safety of the safety hammer 100.

[0047] Furthermore, the two branches independently collect their respective operating condition signals, only integrating them into a single control signal at the junction and transmitting it to the power supply control terminal of the drive component 5. Thus, the normally closed branch containing the energy storage sensor 812 ensures the energy storage phase is connected, and disconnection and shutdown locking occur when energy storage is complete. The normally open branch containing the hammer impact sensor 912 only conducts and triggers hammering after pressure is applied at the front end 141. In other words, the two independent branches ensure that the two operating condition signals do not interfere with each other, thereby ensuring consistent energy storage strokes and reliable hammer impact triggering conditions; thus, not only is consistent hammering force ensured and work efficiency improved, but accidental activation is also prevented.

[0048] In one embodiment, the safety hammer 100 is further provided with a signal processing unit, which is used to collect and identify the on / off status of the branch where the energy storage sensor 812 is located and the branch where the hammer impact sensor 912 is located.

[0049] When the energy storage sensor 812 is triggered, the corresponding branch is disconnected, and the branch containing the impact sensor 912 remains disconnected, the signal processing unit can output a shutdown command to stop the drive assembly 5. When the impact sensor 912 is triggered, the corresponding branch is turned on, and the branch containing the energy storage sensor 812 remains disconnected, the signal processing unit can output a power-on command to allow the drive assembly 5 to continue operating and at least separate from the impact assembly 2.

[0050] In this embodiment, the signal processing unit collects and identifies the on / off signals of the branch where the energy storage sensor 812 is located and the branch where the hammer impact sensor 912 is located, and performs logical judgment. The start / stop control command is only output when the two branches meet the preset combination of working conditions, thereby avoiding the drive component 5 from being started or stopped erroneously, thus preventing erroneous hammering under no-load conditions and improving the operational safety of the safety hammer 100.

[0051] Furthermore, the two branch circuits only output start-stop control commands when the preset working conditions are met, enabling the drive component 5 to start and stop precisely. This not only prevents the energy storage element from being over-compressed and damaging the equipment, but also ensures that the energy storage stroke is consistent each time and the hammering force is stable, thereby improving the stability of the hammering operation and the service life of the equipment.

[0052] To ensure the proper triggering of the energy storage sensor 812, in one embodiment, please refer to... Figure 2 and Figure 3 The energy storage triggering component 81 also includes an energy storage excitation unit 811. One of the energy storage excitation unit 811 and the energy storage sensing unit 812 is disposed in relation to the hammering component 2 and / or the energy storage element, and the other is disposed in the housing 1. When the hammering component 2 is retracted, the energy storage excitation unit 811 and the energy storage sensing unit 812 are coupled and triggered.

[0053] In this embodiment, the drive component 5 is combined with the hammering component 2 and pushes the hammering component 2 to move to the first energy storage position to compress the energy storage element and complete energy storage. When the hammering component 2 moves to the first energy storage position, the energy storage trigger component 81 is coupled and triggered, which can disconnect the branch where the energy storage sensor 812 is located and stop the drive component 5, so that the hammering component 2 and the energy storage element remain in the first energy storage position.

[0054] In this way, by adopting the pre-energy storage mode, the energy storage element is compressed and locked in advance during the hammer-on standby phase. When the hammer is triggered, there is no need to spend time performing the energy compression and storage action. The energy storage element can release energy instantly to drive the hammer component 2 to strike, improve the response speed of the hammer component 2, shorten the interval between hammer triggering and execution, and ensure that the user can break the window and escape at the best time.

[0055] Simultaneously, through the coupling triggering of the energy storage excitation unit 811 and the energy storage sensing unit 812, the drive circuit is automatically cut off and the drive unit 53 stops immediately upon reaching the energy storage target, thereby ensuring accurate energy storage stroke, saving energy storage time, and making the overall response rhythm compact. The energy storage excitation unit 811 and the energy storage sensing unit 812 can be flexibly arranged inside the safety hammer 100, thereby ensuring the compact structure and miniaturization of the safety hammer 100.

[0056] Furthermore, the setting of the energy storage trigger component 81 ensures that the hammer impact component 2 is precisely locked in the same position each time, the compression deformation of the energy storage element is fixed, and the elastic potential energy stored each time is consistent. This not only ensures that the hammer impact force is uniform and stable each time, but also avoids energy storage deviation correction and further improves the response speed.

[0057] The present invention does not impose specific restrictions on the placement of the energy storage excitation unit 811 and the energy storage sensing unit 812. The energy storage excitation unit 811 or the energy storage sensing unit 812 may be disposed separately on the hammer assembly 2, disposed separately on the energy storage element, or disposed simultaneously on the hammer assembly 2 and the energy storage element; correspondingly, the energy storage sensing unit 812 or the energy storage excitation unit 811 is disposed on the housing 1.

[0058] The present invention does not impose specific limitations on the triggering methods of the energy storage excitation unit 811 and the energy storage sensing unit 812. In one embodiment, the energy storage excitation unit 811 and the energy storage sensing unit 812 are configured with mechanical contact coupling. The energy storage excitation unit 811 displaces and presses against the energy storage sensing unit 812 to form a physical coupling, thereby generating an electrical signal. For example, the energy storage sensing unit 812 is configured as an energy storage micro switch; the energy storage excitation unit 811 is correspondingly configured as a pressing part.

[0059] In another embodiment, the energy storage excitation unit 811 and the energy storage sensing unit 812 are configured for non-contact field-inductive coupling, relying on magnetic fields or optical paths to form signal coupling. For example, the energy storage sensing unit 812 is configured as an energy storage signal receiving unit; the energy storage excitation unit 811 is correspondingly configured as an energy storage signal transmitting unit.

[0060] The following explanation uses the example of "the energy storage excitation unit 811 and the energy storage sensing unit 812 being configured with mechanical contact coupling".

[0061] In one embodiment, please refer to Figure 2 and Figure 3The energy storage sensor 812 is disposed on the housing 1 and has an energy storage contact 813 that can be pressed elastically; the energy storage excitation part 811 is configured as a pressing part and is disposed corresponding to the hammer assembly 2 and / or the energy storage element and can be linked with it. When the hammer assembly 2 is retracted to the first energy storage position, the energy storage excitation part 811 moves to press the energy storage contact 813 so that the two are coupled and triggered.

[0062] In this embodiment, the elastically pressable energy storage contact 813 serves as the energy storage sensor 812, and the energy storage excitation unit 811 actively presses against the energy storage contact 813, achieving branch connection and disconnection through purely mechanical hard contact. When the hammer assembly 2 retracts to the first energy storage position, the energy storage excitation unit 811 moves accordingly to press against the energy storage contact 813, directly and physically cutting off the branch where the energy storage sensor 812 is located. The drive assembly 5 immediately stops operating and locks the hammer assembly 2 to complete the pre-energy storage. Thus, the hammer trigger response has no electrical delay, allowing for precise control of the spring compression stroke, avoiding ineffective time consumption caused by over-energy storage or insufficient energy storage, and further improving the response speed of hammer triggering and execution.

[0063] The energy storage contact 813 is designed with an elastic pressing structure, which can compensate for dimensional tolerances caused by component processing and assembly. Even if there is a slight positional deviation in the movement of the hammer assembly 2, the energy storage excitation unit 811 can still squeeze the energy storage contact 813 to disconnect the circuit. At the same time, the elastically pressable energy storage contact 813 has its own buffering capacity after being compressed, avoiding the problems of energy storage contact 813 breaking or energy storage excitation unit 811 deforming due to rigid impact, thereby ensuring the stability of the long-term pre-energy storage function of the safety hammer 100.

[0064] Meanwhile, the pure mechanical hard contact between the energy storage excitation unit 811 and the energy storage contact 813 enables signal triggering, which is less affected by dust, slight vibration, temperature and electromagnetic interference. This avoids the problem of invalid energy storage or repeated energy replenishment due to sensor failure, shortens the energy storage time, ensures stable and effective energy storage, and thus ensures the instantaneous response effect of hammering.

[0065] Similarly, to ensure the proper triggering of the hammer impact sensor 912, in one embodiment, please refer to... Figure 2 , Figures 4 to 6 The hammer triggering assembly 91 also includes a hammer excitation part 911, which is coupled to trigger the hammer excitation part 911 and the hammer sensing part 912 when the front end 141 of the housing 1 presses against the surface to be hammered.

[0066] In this embodiment, the hammer excitation unit 911 and the hammer sensing unit 912 can only be coupled and triggered when the front end 141 of the housing 1 is pressed tightly against the surface to be hammered, and the branch where the hammer sensing unit 912 is located can be connected. At this time, the drive assembly 5 can drive the hammer assembly 2 to switch to the hammering state, allowing the hammer head 21 to extend from the front end 141 to complete the hammering action.

[0067] This design prevents accidental activation, avoiding accidents such as operator injury or equipment damage during handling, accidental contact, or button jamming, thus improving the safety of the safety hammer 100. Furthermore, the triggering condition is clearly defined: the hammer strikes only when the front end 141 is fully pressed down. The control logic is simple, reliable, and has a low failure rate.

[0068] Meanwhile, relying on the conditional triggering mechanism of the front end 141 pressure coupling, each hammer blow is based on the premise that the front end 141 is in contact with the surface to be hammered. This not only reduces the risk of accidental impact caused by the hammer head 21 extending without a target, thus reducing the probability of safety accidents, but also enables the hammer head 21 to act precisely on the surface to be hammered, improving hammering efficiency and blasting success rate.

[0069] The present invention does not impose specific limitations on the triggering methods of the hammer excitation unit 911 and the hammer impact sensing unit 912. In one embodiment, the hammer excitation unit 911 and the hammer impact sensing unit 912 are configured with mechanical contact coupling. The hammer excitation unit 911 displaces and compresses the hammer impact sensing unit 912 to form a physical coupling, thereby generating an electrical signal. For example, the hammer impact sensing unit 912 is configured as an energy storage microswitch; the hammer excitation unit 911 is correspondingly configured as a pressing part.

[0070] In another embodiment, the hammer excitation unit 911 and the hammer sensing unit 912 are configured for non-contact field-inductive coupling, relying on magnetic fields or optical paths to form signal coupling. For example, the hammer sensing unit 912 is configured as an energy storage signal receiving unit; the hammer excitation unit 911 is correspondingly configured as an energy storage signal transmitting unit.

[0071] The following explanation uses the example of "the hammer excitation unit 911 and the hammer sensing unit 912 being configured with mechanical contact coupling".

[0072] In one embodiment, please refer to Figure 2 , Figures 4 to 6 The hammering sensing unit 912 has a resiliently pressable hammering contact 913; the hammering excitation unit 911 is movably disposed at the front end 141. When the front end 141 presses against the surface to be hammered, the hammering excitation unit 911 is pressed inward from the front end 141 and presses against the hammering contact 913, so that the two are coupled and triggered.

[0073] In this embodiment, when the front end 141 presses against the surface to be hammered, the hammering excitation part 911 of the front end 141 is pushed back by the surface to be hammered, thereby squeezing the hammering contact 913 of the hammering sensing part 912, and the branch where the hammering sensing part 912 is located is connected. In scenarios such as handling, accidental contact, and button jamming, safety accidents such as operator injury or equipment damage can be avoided, thereby improving the safety of the safety hammer 100.

[0074] The hammer excitation unit 911 is movably located at the front end 141. During operation, the protruding part of the hammer excitation unit 911 first contacts the surface to be hammered. As soon as the front end 141 is in contact with the surface to be hammered, the hammer excitation unit 911 immediately retracts axially, directly mechanically pressing the hammer contact 913 to complete the branch circuit connection. This results in a short transmission link and fewer intermediate transmission components. On the one hand, this improves trigger sensitivity; on the other hand, the elastically pressed hammer contact 913 ensures that the hammer excitation unit 911 automatically springs back to its original position after the pressure is released, and the branch circuit is immediately disconnected. The trigger lock is automatically released after a single hammering operation is completed. The next operation requires pressing the surface to be hammered again to trigger it again, which conforms to the operational safety logic and avoids the risk of continuous accidental hammering.

[0075] Continuing from the above, in the first stage, the energy storage sensor 812 and the hammer impact sensor 912 are electrically connected in parallel and form a parallel branch, which is electrically connected in series with the drive component 5.

[0076] In one embodiment, please refer to Figure 2 , Figure 4 and Figure 8 The safety hammer 100 also includes a user-operated operation sensor 71, which is located in the housing 1. When both the hammer impact sensor 912 and the operation sensor 71 are triggered, the drive assembly 5 can drive the hammer impact assembly 2 to move until it separates from the hammer impact assembly 2. When the operation sensor 71 is triggered but the hammer impact sensor 912 is not triggered, the drive assembly 5 can drive the hammer impact assembly 2 to retract and the energy storage element to store energy. When the energy storage element stores energy to a preset state, the energy storage sensor 812 is triggered. When the energy storage element reaches the first energy storage position, the energy storage element stores energy to the preset state. In this way, not only can the safety risk of accidental hammering be reduced by the constraint of the hammer impact triggering module, but also efficient hammering can be achieved by relying on pre-stored energy, thus balancing work efficiency and operational safety.

[0077] Specifically, the parallel branch consisting of the energy storage sensor 812 and the impact sensor 912 is connected in series with the drive assembly 5 to form the first series segment. The operation sensor 71 is electrically connected in series with the first series segment and connected to the signal circuit.

[0078] When the operation sensor 71 is triggered but the energy storage sensor 812 and the hammer impact sensor 912 are not triggered, the signal circuit is connected, and the drive assembly 5 drives the hammer impact assembly 2 to retract. When the operation sensor 71, the energy storage sensor 812, and the hammer impact sensor 912 are triggered, the signal circuit is connected, and the drive assembly 5 can at least move and separate from the hammer impact assembly 2.

[0079] In this embodiment, the safety hammer 100 is also equipped with a work sensing unit 71, such as a start switch 7. The start switch 7 is electrically connected in series with the first series segment to the signal circuit. Only when the user actively presses the start switch 7 will the signal circuit of the whole machine have the prerequisite for conduction. That is to say, when the start switch 7 is not pressed, no matter what electrical abnormality occurs in the two sensing branches, the signal circuit will always be disconnected, and the drive component 5 will not be able to start the energy storage action, thereby avoiding the safety risks of the safety hammer 100 accidentally storing energy or accidentally striking the hammer.

[0080] When the start switch 7 is triggered, but the energy storage sensor 812 and the hammer impact sensor 912 are not triggered, the signal circuit is connected, and the drive assembly 5 performs retraction energy storage. Once the energy storage is complete and the energy storage sensor 812 triggers and disconnects its branch, even if the start switch 7 remains pressed, the signal circuit will disconnect, and the drive assembly 5 will automatically stop and lock the energy storage to the preset state. At this time, the user can move or adjust the working posture of the pre-stored and locked safety hammer 100. This avoids user fatigue and does not affect the efficient hammering operation after pre-stored energy.

[0081] When the front end 141 presses against the surface to be hammered, and the start switch 7, the energy storage sensor 812, and the hammer impact sensor 912 are triggered, the signal circuit is turned on, and the drive component 5 is activated to achieve the separation of the drive component 2 and release the hammer impact.

[0082] To facilitate the user's hammering operation, in one embodiment, please refer to... Figures 1 to 4 The housing 1 includes at least a main body 13 and a rear grip 12. The main body 13 has a front end 141 at one end on the front side. The rear grip 12 is located on the periphery of the main body 13 and the extension axes of the two are arranged to intersect. The hammering assembly 2 is movably located on the main body 13 in the front-rear direction.

[0083] In this embodiment, the axes of the main body 13 and the rear grip 12 intersect to form a gun-style grip structure, which facilitates stable gripping by the user and applies pressure to the front end 141 of the main body 13, ensuring that the front end 141 reliably presses against the surface to be hammered, so that the hammer triggering component 91 is stably coupled and connected, thereby ensuring that the safety hammer 100's anti-misfire triggering safety mechanism is effectively realized.

[0084] Meanwhile, the hammering component 2 is arranged along the front and rear direction of the main body 13, and the hammering motion direction is consistent with the pressing direction of the front end 141 and the triggering direction of the hammering excitation part 911, ensuring the timing logic of triggering first and then hammering, thereby improving the safety of operation and the accuracy of hammering positioning.

[0085] Specifically, please refer to Figures 1 to 4The operation sensor 71 is located on the rear handle 12 and near the connection between the rear handle 12 and the main body 13. It is understood that the connection between the rear handle 12 and the main body 13 is a stress concentration area when gripping. During operation, the user grips the rear handle 12 and exerts force to move the safety hammer 100, pressing the front end 141 against the surface to be hammered. At this time, the user can touch the operation sensor 71 to make the entire hammering action smooth and continuous.

[0086] In one embodiment, please refer to Figures 1 to 4 The housing 1 also includes a front grip 11 and a connecting rod 15. The front grip 11 and the rear grip 12 are arranged side by side in the front-rear direction. The connecting rod 15 is arranged in the front-rear direction and connects the rear grip 12 and the front grip 11 to form a grip gap together. The work sensor 71 is located in the grip gap.

[0087] In this embodiment, the front grip 11 and the rear grip 12 are arranged side by side in the front-rear direction, and the connecting rod 15 connects the two in the front-rear direction, forming a grip gap. During operation, the user holds the front grip 11 and the rear grip 12 with both hands respectively, so that the front end 141 can be reliably pressed against the surface to be hammered, ensuring that the hammering trigger component 91 of the front end 141 can be smoothly coupled and connected under pressure, thereby improving the triggering sensitivity.

[0088] Meanwhile, the operation sensor 71 is positioned within the grip gap. The operation sensor 71 can only be triggered when the user's hand enters the grip gap and presses it, thus further improving the prevention of accidental triggering. Furthermore, the grip gap is a semi-enclosed protective space, preventing dust or debris during operation from directly eroding the operation sensor 71, thereby enhancing the stability of the overall machine control circuit.

[0089] Continuing on the above, the safety hammer 100 is also provided with a work sensor 71, such as a start switch 7. To facilitate user operation of the touch-sensitive work sensor 71, in one embodiment, please refer to... Figures 1 to 4 ,as well as Figure 8 The operation sensing unit 71 includes an operation pressure on / off unit 711 and a trigger 712. The trigger 712 is movably disposed on the rear grip 12 and near the connection between the rear grip 12 and the main body 13. The trigger 712 protrudes at least partially from the outer wall of the rear grip 12 for the user to press.

[0090] The working pressure switching unit 711 is located inside the rear grip 12, and its working contact is set corresponding to the trigger 712, so that when the user presses the trigger 712, the trigger 712 presses against the contact of the working pressure switching unit 711.

[0091] In this embodiment, the operation sensing unit 71 employs a mechanical on / off structure consisting of a trigger 712 and an operation pressure on / off unit 711. Only when the user actively presses the trigger 712 can the operation contact be squeezed to activate the signal circuit. Accidental bumps, foreign objects squeezing the handle, or simply holding the handle will prevent the trigger 712 from being pulled, thus keeping the signal circuit disconnected. The manual operation lock of actively pressing the trigger 712 further improves the effect of preventing accidental triggering.

[0092] The mechanical on / off structure of the trigger 712 in conjunction with the working pressure on / off unit 711 is not easily affected by the working environment, and the trigger recognition is stable and reliable, thereby further improving the sensitivity and reliability of triggering. At the same time, the pressure on / off unit is located inside the rear grip 12, and is protected by the housing 1, thereby reducing the probability of failure of the pressure on / off unit and extending its service life.

[0093] Meanwhile, the trigger 712 is movably located on the rear grip 12 and near the connection between the rear grip 12 and the main body 13. The trigger 712 protrudes at least partially from the outer wall of the rear grip 12 for the user to press and operate. In this way, when the user holds the rear grip 12, the fingers can naturally press the trigger 712, which conforms to the human operating habits and makes it convenient for the user to hold and operate.

[0094] It is understandable that in some scenarios, users need to perform hammering operations in a dark environment. For ease of user operation, please refer to one embodiment. Figure 1 and Figure 8 The safety hammer 100 also includes a power supply unit 93 and a lighting unit 92. The lighting unit 92 is electrically connected to the power supply unit 93, and the power supply unit 93 can supply power to the lighting unit 92. The lighting unit 92 is located at the front end and is electrically connected to the operation sensor unit 71. The direction of the illumination light from the lighting unit 92 is parallel to the extension direction of the hammer impact assembly 2. In this embodiment, the lighting unit 92 is provided to facilitate the determination of the hammer impact point in low-light environments such as at night or in enclosed spaces, thereby improving the efficiency of emergency operations and the accuracy of hammer impact. Moreover, the parallelity of the illumination light direction of the lighting unit 92 to the extension direction of the hammer impact assembly 2 is more conducive to the precise positioning of the hammer impact point, making the window breaking operation more accurate.

[0095] Specifically, the lighting unit 92 is located at the front end 141. The lighting unit 92 is electrically connected in parallel with the first series segment and forms a parallel assembly. The parallel assembly and the operation sensor 71 are connected in series to the signal circuit so that when the operation sensor 71 is triggered to conduct, the branch where the lighting unit 92 is located is turned on and the lighting unit 92 is turned on.

[0096] In this embodiment, the lighting unit 92 reuses the trigger circuit of the work sensor 71. When the work sensor 71 is triggered and turned on, the lighting unit 92 is turned on synchronously. There is no need to operate the lighting switch separately, which makes it easier to determine the hammering point in low light environments such as at night and in enclosed spaces, thereby improving the efficiency of emergency operations and the accuracy of hammering operations.

[0097] Please see Figure 2 and Figure 8 The power supply unit 93 provides centralized power to the signal circuit of the entire machine, and can provide unified working power to the drive component 5, various sensors, and lighting unit 92, ensuring the coordinated and stable operation of all electrical components. At the same time, the power supply unit 93 is connected in series with the signal circuit, and the entire machine is powered on by the start switch 7. When the start switch 7 is turned off, the entire signal circuit is de-energized, which not only reduces standby power consumption and extends battery life, but also further prevents accidental activation and improves the safety of the safety hammer 100.

[0098] Continuing from the above, the housing 1 includes at least a main body 13 and a rear grip 12. The rear grip 12 is hollow, and a trigger 712 is movably disposed in the rear grip 12 and located near the connection between the rear grip 12 and the main body 13. A working pressure on / off unit 711 is disposed within the rear grip 12, and its working contact is disposed corresponding to the trigger 712. In one embodiment, please refer to... Figure 2 The power supply unit 93 is housed within the rear handle 12. This not only makes the overall structure of the safety hammer 100 compact, facilitating its miniaturization and portability, but also makes it easier to route the wiring between the operation sensor 71 and the power supply unit 93.

[0099] As mentioned above, an energy storage element is connected between the hammering assembly 2 and the housing 1. In one embodiment, please refer to... Figure 2 , Figure 4 and Figure 7 The drive assembly 5 includes a drive section 53 that can be disengaged to drive the hammer assembly 2. The drive section 53 is movably configured and has a continuous first stroke and a second stroke.

[0100] In the initial state, the start switch 7 is not triggered, the signal circuit is disconnected, and the safety hammer 100 is in standby mode. When the user operates to trigger the start switch 7, the start switch 7 is triggered, the energy storage sensor 812 is not triggered, the hammer impact sensor 912 is not triggered, the signal circuit is connected, and the drive unit 53 moves along the stroke to enter the first stroke segment.

[0101] During the first stroke, the drive unit 53 and the hammer assembly 2 remain in a close contact state, continuously pushing the hammer assembly 2 backward, compressing the energy storage element located between the hammer assembly 2 and the housing 1 to deform, converting the mechanical energy output by the drive unit 53 into the elastic potential energy of the energy storage element, completing the energy storage process before hammering. At this time, the hammer assembly 2 is in the energy storage state.

[0102] When the hammer assembly 2 moves to the first energy storage position, the start switch 7 is triggered, the energy storage sensor 812 is triggered, and the hammer impact sensor 912 is not triggered. The signal circuit is disconnected, and the drive unit 53 is controlled and locked, preventing it from entering the second stroke. Even if the first stroke pre-energy storage is completed, it cannot continue to compress the energy storage element, nor will it detach from the hammer assembly 2 to release potential energy. This locks the hammer assembly 2 in the first energy storage position, preventing accidental release after energy storage from causing dry firing and mis-triggering.

[0103] When the front end 141 presses against the surface to be hammered, the start switch 7 is triggered, the energy storage sensor 812 is triggered, and the hammer impact sensor 912 is triggered, the signal circuit is turned on, and the drive unit 53 continues to move along the stroke into the second stroke segment. During this stage, the drive unit 53 continues to push the hammer impact assembly 2 a little further, further compressing the energy storage element, so that the hammer impact assembly 2 can move further to the second energy storage position, allowing the energy storage element to store more elastic potential energy.

[0104] It should be noted that the second stroke segment is much shorter than the first stroke segment. Taking the drive assembly 5, which includes the motor 51, the gearbox 52, and the cam structure 4, as an example, please refer to [link to relevant documentation]. Figure 2 , Figure 3 and Figure 7 The motor 51 drives the cam structure 4 to move through the reduction gearbox 52. The reduction gearbox 52 and the cam structure 4 form the drive unit 53. The cam structure 4 includes a rotating disk 41 and an abutment pin 42. The abutment pin 42 is connected to the rotating disk 41 to form a clutch push part 43. The center line of the abutment pin 42 is parallel to the rotation axis of the rotating disk 41. The abutment pin 42 is a protruding end 431. The abutment pin 42 and the hammer assembly 2 form a clutch drive. The rotating disk 41 is configured as a cam, and the abutment pin 42 is set perpendicular to the rotating disk 41 and close to the distal end of the rotating disk 41. When the rotating disk 41 rotates, it can drive the abutment pin 42 to move.

[0105] During the first stroke, the abutment pin 42 rotates with the rotating disk 41. As the radial profile of the rotating disk 41 gradually increases, the abutment pin 42 continuously pushes the hammering assembly 2 backward, constantly compressing the energy storage element. When the rotating disk 41 reaches the end position of the first stroke, the radial profile of the rotating disk 41 reaches its maximum value for this segment. At this time, the hammering assembly 2 is pushed to its furthest point in this segment, and the energy storage element is compressed to its maximum compression amount during the first stroke, completing pre-energy storage. At this point, the abutment pin 42 remains in contact with the hammering assembly 2 and does not disengage, thus locking the hammering assembly 2 in the first energy storage position.

[0106] When the branch containing the hammer impact sensor 912 is activated, the rotating disk 41 continues to rotate, entering the second stroke segment. Based on the maximum push stroke of the first stroke segment, the radial direction of the subsequent profile of the rotating disk 41 will increase slightly, thus allowing it to push the hammer impact assembly 2 backward slightly again, further compressing the energy storage element and further increasing the total elastic potential energy.

[0107] Although the second stroke is very short, it not only eliminates the assembly and transmission gaps between the abutment pin 42 and the hammering assembly 2, preventing hammering force attenuation and action lag, but also allows for further energy storage on top of pre-stored energy, ensuring that subsequent hammering impact force meets operational requirements. Based on pre-stored energy, the short second stroke also enables rapid hammering after the hammering signal circuit is activated.

[0108] The end point of the second stroke segment is the global maximum value of the profile radius of the rotating disk 41. After passing this point, the profile radius of the rotating disk 41 will suddenly decrease, realizing the disengagement of the drive unit 53 from the hammer assembly 2.

[0109] Therefore, after the drive unit 53 completes the second stroke, the drive unit 53 and the hammering assembly 2 disengage, and the two no longer resist each other; the fully compressed energy storage element instantly rebounds and releases the stored elastic potential energy, quickly driving the hammering assembly 2 to move in the opposite direction, so that the hammer head 21 extends from the front end 141 of the housing 1, and switches to the hammering state to complete the hammering operation.

[0110] In other words, the drive unit 53 first runs the first stroke, pushing the hammer impact assembly 2 to compress the energy storage element to achieve pre-energy storage, thereby improving the response speed of the safety hammer 100 in the second stroke and subsequent hammer impact triggering and execution, ensuring that the user can break the window and escape at the best time; when the hammer impact signal circuit is connected and the safety triggering condition is met, the drive unit 53 can continue to enter the second stroke to further compress the energy storage element and accumulate hammer impact potential energy; when the short second stroke ends, the drive unit 53 disengages from the hammer impact assembly 2, and the energy storage element releases elastic potential energy to drive the hammer impact assembly 2 to switch to the hammer impact state and quickly complete the hammer impact.

[0111] The two-stage stroke graded control is adopted. The second stroke can only be unlocked after the hammer signal circuit is turned on. The hammer energy cannot be released in the pre-stored state. The drive unit 53 forms a safety lock, which can effectively prevent accidental release of stored energy and cause injury by hitting without impact, thereby improving the safety of the safety hammer 100.

[0112] Meanwhile, the segmented compression of the energy storage element in the first and second strokes can accurately control the amount of energy stored in the hammer blows, ensuring that the force of each hammer blow is uniform and stable, and improving the accuracy of the hammering operation.

[0113] Furthermore, the first stroke pre-stores energy in advance, and the hammering can be completed quickly after the operation is triggered, resulting in fast operation response and high work efficiency.

[0114] Continuing on the above, housing 1 also includes a front grip 11 and a connecting rod 15. In one embodiment, please refer to... Figures 2 to 4The front grip 11 is hollow, and at least part of the drive assembly 5 is housed within it. For example, the motor 51 and gearbox 52 of the drive assembly 5 are housed within the front grip 11. In some embodiments, the cam structure 4 of the drive assembly 5 may also be housed within the front grip 11. This allows for a compact overall structure of the safety hammer 100, facilitating its miniaturization and portability.

[0115] This invention also provides a control system for a safety hammer 100, used to control the safety hammer 100. This control system includes a first electrical circuit and a second electrical circuit connected in parallel. The first electrical circuit includes a power supply unit 93, a motor 51, a first start switch, and an energy storage trigger component 81 connected in series. The second electrical circuit includes a power supply unit 93, a second start switch, a hammer impact trigger component 91, and a motor 51 connected in series. The motor 51 is used to control the start and stop of the drive component 5 of the safety hammer 100. In one embodiment, the first start switch and the second start switch are the same start switch, for example, start switch 7. This not only reduces the safety risk of accidental hammering through the constraint of the hammer impact trigger module 91, but also achieves efficient hammering by relying on pre-stored energy, thus balancing work efficiency and operational safety. Since the first start switch and the second start switch are the same start switch, controlling the energy storage trigger component 81 and the hammer impact trigger module 91 through a single start switch makes operation simpler and more convenient.

[0116] In another embodiment, the first start switch and the second start switch are connected in series. That is, the first start switch and the second start switch are independent of each other and connected in series, which can achieve dual protection, such as realizing the function of a child safety lock.

[0117] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention in any way. Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present invention. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present invention without departing from the scope of the present invention shall still fall within the scope of the present invention.
