Nail shooting drive control mechanism and nail gun

Abstract

The present application belongs to the technical field of fastening tools, and particularly relates to a nail shooting drive control mechanism and a nail gun. The nail shooting drive control mechanism comprises a drive assembly and a control assembly. The drive assembly has a piston, at least one power supply spring and a drive motor. The control assembly has a main switch and a safety switch. The main switch, the safety switch and the drive motor are electrically connected. When the main switch element and the safety switch element both generate an electrical signal, the drive motor operates. The toggle part contains a toggle piece, a toggle rod and a toggle piece seat. A toggle piece return spring is arranged in the toggle part. One end of the toggle piece abuts against the toggle piece return spring, and the other end of the toggle piece extends out of the toggle piece seat and is linked with the toggle rod. Since the pushing member is arranged and directly cooperates with the piston, the pushing member is used to push the piston to move towards the power supply spring, so that the power supply spring is compressed to store energy. The pushing member is not in direct contact with the striker, which avoids affecting the movement of the piston due to the contact between the pushing member and the striker, so that the entire energy storage process is smoother and more stable.

Description

Technical Field

[0001] This invention belongs to the field of fastening tool technology, specifically relating to a nail drive control mechanism and a nail gun. Background Technology

[0002] A nail gun is a fastening tool, primarily used in construction. Currently, a widely used type of nail gun is the electric nail gun powered by a lithium battery. This type of nail gun is powered by a lithium battery, which drives a motor and a corresponding drive structure to push a piston. The piston then compresses a force spring to store energy. When firing a nail, the spring force drives the piston, which in turn moves a firing pin mounted on the piston to strike and eject the nail. For details, please refer to the applicant's prior patent CN215395034U.

[0003] However, there are still some shortcomings in the above-mentioned patented technologies. For example, the drive structure uses a gear and a toothed pin to make the power supply spring store energy. The gear and toothed pin are prone to wear and jamming during long-term use, which can lead to poor transmission or even jamming of the nail gun, making it impossible to shoot nails. At the same time, a separate circuit controller needs to be set up inside the nail gun to control the operation of the motor, which is costly. Summary of the Invention

[0004] To address the aforementioned problems, this invention provides a compact nail drive control mechanism that utilizes a spring for energy storage, directly relying on the movement of a drive piston for smoother energy storage, and employs mechanical control to operate the drive motor, resulting in easier operation and lower cost. The invention also includes a nail gun using this drive mechanism. The technical solution adopted by this invention is as follows:

[0005] This invention proposes a nail gun drive control mechanism, disposed within a nail gun having a housing and a handle for user grip, for controlling and driving the nail of the nail gun to fire. It is characterized by comprising: a drive assembly for driving the nail to fire along a striking direction; and a control assembly for controlling the operation of the drive assembly. The drive assembly includes: a piston movably disposed within the housing and fitted with a firing pin for striking the nail; at least one force spring abutting against the piston; a pushing member for pushing the piston toward the force spring, thereby compressing and storing energy in the force spring; and a drive motor for driving the pushing member. The control assembly includes: a main switch having a pressing part and a main switch element; a safety switch having a toggle part and a safety switch element; the main switch, the safety switch, and the drive motor are electrically connected, and the drive motor runs when both the main switch element and the safety switch element generate electrical signals; the toggle part includes: a paddle for contacting the contact point of the safety switch element to generate an electrical signal; a lever, one end of which is linked to a pushing member and the other end of which is linked to the paddle, for pushing the paddle to disconnect it from the safety switch element; and a paddle seat having a paddle return spring inside, one end of which abuts against the paddle return spring and the other end of which extends out of the paddle seat and is linked to the lever.

[0006] The nail drive control mechanism proposed in this invention may also have the following features: the lever is hook-shaped and has: a contact plate for contacting the actuation point of the safety switch element; a toggle plate for contacting the lever; and a connecting plate for connecting the contact plate and the toggle plate; the length of the contact plate is less than the length of the toggle plate, and the difference in length between the two forms a gap; when the actuation point of the safety switch element contacts the contact plate, the safety switch element generates an electrical signal; when the actuation point of the safety switch element is located in the gap, the safety switch element disconnects the electrical signal.

[0007] The nail-driving control mechanism proposed in this invention may also have the following features, wherein the lever comprises: a first lever disposed near the pushing member; a second lever disposed near the paddle; and a connecting section for connecting the first lever and the second lever, and is rotatably disposed within the housing via a pin; when the pushing member rubs against the first lever during rotation, the second lever contacts the paddle and pushes the paddle to move.

[0008] The nail drive control mechanism proposed in this invention may also include: a crank assembly for driving the paddle and safety switch element in linkage, and having: an outer crank, the outer end of which extends to the outside of the nozzle mechanism of the nail gun and the inner end inserted into the housing of the nail gun; an inner crank, the outer end of which is linked with the outer crank and the inner end of which is combined with the paddle seat; and a crank return spring provided at the end of the inner crank near the outer crank.

[0009] The nail drive control mechanism proposed in this invention may also have the following features: the pushing member has a pushing end facing the piston, and the piston is provided with a resisting end that cooperates with the pushing end. The resisting end has: a first resisting end extending from the piston along the nail firing direction of the nail gun, and a second resisting end extending from the piston toward the pushing member. The pushing end has: a first pushing end cooperating with the first resisting end, and a second pushing end cooperating with the second resisting end, and its outer diameter is smaller than the outer diameter of the first pushing end.

[0010] The nail drive control mechanism proposed in this invention may also have the following feature: the pushing member further has a crank, which includes: a first crank arm for mounting a first pushing end, a second crank arm for mounting a second pushing end and being the same length as the first crank arm, and an included angle between the first crank arm and the second crank arm.

[0011] The nail drive control mechanism proposed in this invention may also have the following features: the first push end and the second push end are both cylindrical and are respectively disposed at the outer ends of the first crank arm and the second crank arm. The outer ends of the first crank arm and the second crank arm are arc-shaped, and the outer edge of the first push end protrudes from the outer end of the first crank arm.

[0012] The nail-driving control mechanism proposed in this invention may also have the following features: a pushing member is installed at the output end of a drive motor, and a one-way rotating member is provided between the pushing member and the output end. When the pushing member rotates under the drive of the drive motor, the first pushing end abuts against the first pushing end and pushes the first pushing end, causing the piston to move toward the force-supplying spring, thereby causing the force-supplying spring to perform the first stage of energy storage. After the first stage of energy storage is completed, the second pushing end abuts against the second pushing end and pushes the second pushing end, causing the piston to move toward the force-supplying spring, thereby causing the force-supplying spring to perform the second stage of energy storage.

[0013] The nail-driving control mechanism proposed in this invention may also have the following features, wherein the drive motor includes: a motor body having an output shaft; a reducer mounted on the output shaft and having an output end for mounting a pushing component; and a unidirectional rotating component having: a ratchet sleeved on the output end and having a plurality of ratchet teeth; a pawl disposed on the side of the ratchet for inserting into the ratchet teeth to engage with them to make the ratchet rotate unidirectionally; and a pawl spring piece, one end of which is mounted on the reducer and the other end of which abuts against the pawl.

[0014] The present invention also proposes a nail gun, which includes at least: a housing having an internal mounting cavity, a nozzle mechanism mounted at the front end of the housing, and a nail drive control mechanism mounted in the mounting cavity, wherein the nail drive control mechanism is the nail drive control mechanism as described above.

[0015] Invention Function and Effect

[0016] According to the nail-driving control mechanism and nail gun of the present invention, a pushing component is provided, which directly cooperates with the piston to push the piston toward the force-supplying spring, thereby compressing and storing energy in the force-supplying spring. The pushing component has no direct contact with the firing pin, avoiding interference with piston movement due to contact with the firing pin, making the entire energy storage process smoother and more stable. Simultaneously, a control component is also included, comprising a main switch, a safety switch, and an electrical connection between the drive motor, main switch, and safety switch. Therefore, the drive motor of the nail gun can be controlled based on the nail-driving electrical signals and safety electrical signals generated by the main switch and safety switch. The dual-switch, dual-safety design ensures safety during nail-driving. Furthermore, the generation and disconnection of the safety switch's electrical signal rely on the mechanical linkage between the lever, lever, and pushing component, eliminating the need for a separate push-button switch and controller. This design makes efficient use of space, is compact, provides rapid linkage, good control effect, and is relatively inexpensive. Attached Figure Description

Detailed Implementation

[0039] To make the technical means, creative features, objectives and effects of the present invention easy to understand, the following describes the nail drive control mechanism and nail gun of the present invention in detail with reference to the embodiments and accompanying drawings.

[0040] <Example 1>

[0041] This embodiment provides a nail drive control mechanism and a nail gun, which are easier to operate and do not affect safety or nailing effect.

[0042] Figure 1 This is a structural diagram of the nail gun according to Embodiment 1 of the present invention.

[0043] Figure 2 This is a structural diagram of the nail gun after part of the housing has been removed, according to Embodiment 1 of the present invention.

[0044] like Figures 1-2As shown, the nail gun 10 of this embodiment includes a housing 20, a nozzle mechanism 30, a nail drive control mechanism 40, and a power supply unit (lithium battery 60). The housing 20 is a casing 21 disposed on the outside. The casing 21 is formed by two front cover plates 211 and a rear cover plate 212 disposed front and rear, which are interlocked. An internal mounting cavity is formed for mounting the nail drive control mechanism 40. The casing 21 can not only accommodate the nail drive control mechanism 40 and other internal components, but also protect these internal components. The main casing 21 includes a handle 213 for the user to hold and a base 214 connected to the handle 213. Both the handle 213 and the base 214 are hollow structures. A mounting slot 2141 is provided on the base 214, and the lithium battery 60 can be detachably mounted in the mounting slot 2141. The power supply unit provides power to the entire nail gun; the nozzle mechanism 30 stores the nails and fires them out; the nail drive control mechanism 40 drives the firing pin to move in a predetermined reciprocating direction, so that it can fire the nails from the nozzle mechanism 30 to achieve nail firing.

[0045] Figure 3 This is a partial structural diagram of the nozzle mechanism in Embodiment 1 of the present invention.

[0046] like Figures 2-3 As shown, the nozzle mechanism 30 is located at the front end of the housing 21. The nozzle mechanism 30 has a magazine 31 for storing nails, a nozzle base plate 32 and a nozzle cover plate 33 mounted on the top of the magazine 31. A nail passage 34 is provided between the nozzle base plate 32 and the nozzle cover plate 33 to allow the nails to be ejected. The firing pin drive assembly 40 is used to strike the nails so that they are ejected from the nail passage 34.

[0047] Figure 4 This is a structural diagram of the nail-driving control mechanism of Embodiment 1 of the present invention.

[0048] like Figure 4 As shown, the nail drive control mechanism 40 includes a drive assembly and a control assembly. The drive assembly drives the nail to fire along the firing direction, while the control assembly controls the operation of the drive assembly. The drive assembly has a piston 41 movably disposed within the housing 20, at least one force spring 42, a pushing member 43, and a drive motor 44 that drives the pushing member 43 to rotate.

[0049] like Figure 2As shown, a slot structure is provided in the mounting cavity inside the housing 21. A cylinder head seat 48 (in this embodiment, the cylinder head seat 48 is a sheet-like structure) is fixed to the front end of this slot structure, and a fixing plate 421 (in this embodiment, the fixing plate 421 is also a sheet-like structure) is fixed to the rear end. A pair of parallel guide rods 422 are provided between the cylinder head seat 48 and the fixing plate 421. The piston 41 is located on the side of the guide rods 422 closest to the cylinder head seat 48, and the guide rods 422 pass through the piston 41 and are fixed to the cylinder head seat 48. A buffer pad 484 is provided between the cylinder head seat 48 and the piston 41 to reduce the collision between the piston 41 and the cylinder head seat 48 during movement. Figure 4 As shown, this embodiment includes two parallel force-supplying springs 42. The front end of each spring 42 is connected to the piston 41, and the rear end rests against the fixing plate 421. The two springs 42 are respectively sleeved on the outer periphery of two guide rods 422. One end of each guide rod 422 is fixed to the fixing plate 421 with screws, and the other end passes through the piston 41 and is fixed to the cylinder head seat 48. The guide rods 422 guide the piston 41 to reciprocate in a predetermined direction.

[0050] The piston 41 has a firing pin 49 mounted at its front end to strike the nail and launch it. The rear end of the piston 41 cooperates with a force spring 42, which drives the piston 41 to move (i.e., the force spring 42 provides power for the movement of the piston 41). The pushing member 43 has a pushing end facing the piston 41, used to push the piston 41 towards the end where the force spring 42 is located, thereby compressing and storing energy in the force spring 42. Correspondingly, the piston 41 has a pushing end that cooperates with the pushing end. The pushing end has a first pushing end 411 and a second pushing end 412. The first pushing end 411 extends from the piston 41 along the nail-firing direction of the nail gun, and the second pushing end 412 extends from the piston 41 towards the pushing member 43. The pushing end has a first pushing end 431 that cooperates with the first pushing end 411 and a second pushing end 432 that cooperates with the second pushing end 412. Both the first pushing end 431 and the second pushing end 432 are cylindrical structures. During the rotation of the pushing component 43, the first pushing end 431 and the second pushing end 432 can be driven to rotate. The outer diameter of the second pushing end 432 is smaller than the outer diameter of the first pushing end 431, and the height of the second pushing end 432 is also lower than the height of the first pushing end 431.

[0051] Figure 5 This is a structural diagram of the nozzle mechanism installation according to Embodiment 1 of the present invention.

[0052] like Figure 5As shown, in the first embodiment of the cylinder head seat 48, the cylinder head seat 48 is located in front of the piston 41 along the striking direction, and a mounting plate 481 is formed extending forward from the lower end. The nozzle base plate 32 and the nozzle cover plate 33 are fixed above the mounting plate 481 by bolts. The front end of the firing pin 49 in the middle of the piston 41 passes through the middle of the cylinder head seat 48 and is inserted into the nail passage 34 between the nozzle base plate 32 and the nozzle cover plate 33. The left and right sides of the cylinder head seat 48 are fixed to the housing by screws 482.

[0053] Figure 6 This is an exploded view of the piston and pushing component of Embodiment 1 of the present invention.

[0054] Figure 7 This is a schematic diagram of the piston and cylinder head seat installation structure in Embodiment 1 of the present invention.

[0055] like Figure 6 and Figure 7 As shown, the piston 41 has a fixing part 413 for fixing the firing pin 49 (the fixing part 413 is generally cylindrical, with a slotted inlet 4131 in the middle along its axial direction, and a fixing hole 4132 extending radially through the entire cylinder; one end of the firing pin 49 is inserted into the slotted inlet 4131, and a pin is inserted into the fixing hole 4132, thereby fixing the firing pin 49 to the fixing part 413). A mounting part 414 for mounting the force-supplying spring 42 is provided on the rear side of the fixing part 413. The mounting part 414 consists of two conical mounting seats 4141 corresponding to the force-supplying spring. Through holes 483 are provided at corresponding positions in the middle of 141, the cylinder head seat 48, and the buffer pad 484. The front ends of the two guide rods 422 pass through the corresponding through holes 483 and are fixed to the cylinder head seat 48. The fixing part 413 and the mounting part 414 are connected by a plate-shaped connecting part 415. The lower end of the connecting part 415 extends downward (in the direction of the pushing member 43) to form a second pushing end 412. One side of the second pushing end 412 extends towards the direction of the fixing part 413 to form a first pushing end 411, and the second pushing end 412 is approximately perpendicular to the first pushing end 411. Figure 7 As shown, as a second embodiment of the cylinder head seat 48, it is only a square plate structure. In this case, the nozzle mechanism is directly fixed to the housing 20, and does not need to be fixed to the cylinder head seat 48. The nozzle base plate 32 can be fixed to the housing 20 with bolts.

[0056] The first pushing end 431 and the second pushing end 432 have a cylindrical structure. The pushing component 43 also has a crank 430, which includes a first crank arm 4301 and a second crank arm 4302. The first pushing end 431 is installed at the outer end of the first crank arm 4301, and the second pushing end 432 is installed at the outer end of the second crank arm 4302. The first crank arm 4301 and the second crank arm 4302 are of equal length and form an angle between them. The outer ends of both are arc-shaped. The outer edge of the first pushing end 431 protrudes from the outer end of the first crank arm 4301, and the outer edge of the second pushing end 432 is flush with or slightly concave to the outer end of the second crank arm 4302.

[0057] like Figure 4 As shown, the drive motor 44 includes a motor body 441 and a reducer 442. The reducer 442 is mounted on the output shaft of the motor body 441, and a pushing member 43 is mounted on the output end of the reducer 442. A one-way rotation member 45 is provided between the two. Driven by the motor body 441 and the reducer 442, the pushing member 43 rotates in one direction. In this embodiment, the motor body 441 is a brushless motor. The reducer 442 is mounted on the output shaft of the motor body 441 to reduce the output speed of the motor body 441, thereby obtaining higher output torque, that is, greater driving force. The one-way rotation member 45 is used to restrict the rotation direction of the output end 443 of the drive motor 44 (i.e., the output shaft of the reducer 442), so that it can only rotate in one direction. The one-way rotation member 45 is mounted on the output shaft of the reducer 442 and forms a hole-shaft fit with the output shaft, so that the output shaft can only rotate in one direction. Simultaneously, when the pushing member 43 is subjected to a driving force that causes it to rotate in the opposite direction, the one-way rotating member 45 bears this driving force, preventing it from being transmitted to the output shaft, thereby protecting the motor body 441. The specific structure of the motor body 441 and the reducer 442 can adopt the structure in the prior art. Furthermore, as... Figure 1 , Figure 2 and Figure 4 As shown, the drive motor and the pushing component 43 are located almost directly below the piston 41, making the entire structure more compact. The gravity is concentrated in the middle of the entire nail gun. Compared with placing the motor and drive components on the side, this is more stable and the force is more even, and it does not take up extra space.

[0058] During installation, a through hole is provided in the middle of the crank 430, at the connection between the first crank arm 4301 and the second push end 432. The crank 430 is installed at the output end of the reducer 442 through this through hole, and the crank 430 can rotate with the motor body 441 and the reducer 442. Designing the push component 43 in the shape of the crank 430 is lighter than the disc structure in the prior art, which not only saves materials but also reduces energy consumption and improves the transmission effect.

[0059] When the pushing member 43 rotates, its first pushing end 431 and second pushing end 432 follow the crank 430 in an arc-shaped motion, and respectively cooperate with the first pushing end 411 and the second pushing end 412 on the piston 41 to push the piston 41 in the energy storage direction. The shape and height of the first pushing end 431 correspond to the arrangement of the first pushing end 411, and the shape and height of the second pushing end 432 correspond to the arrangement of the second pushing end 412.

[0060] Figure 8 This is an installation structure diagram of the unidirectional rotating component and the reducer in Embodiment 1 of the present invention.

[0061] In this embodiment, the unidirectional rotating component can be a unidirectional bearing, or it can be as follows: Figure 8 The ratchet and tooth structure is shown. One-way bearings are a common structure and will not be described in detail here; the focus is on the ratchet and tooth structure in this embodiment. Figure 8 As shown, the unidirectional rotating component 45 has a ratchet 451, a pawl 452, and a pawl spring 453. The ratchet 451 is sleeved on the output end 443 and has a number of ratchet teeth 4511. The pawl 452 is set on the reducer 442 located on the side of the ratchet 451. The pawl 452 is used to insert between the ratchet teeth 4511 and cooperate with them to make the ratchet 451 rotate in one direction. One end of the pawl spring 453 is fixed to the reducer 443 by bolts, and the other end abuts against the pawl 453, so that it always has the tendency to move toward the pawl 452 and insert into the ratchet teeth 4511.

[0062] Figure 9 This is one of the process diagrams of the pushing component cooperating with the piston and pushing the piston to move in Embodiment 1 of the present invention.

[0063] Figure 10 This is the second diagram showing the process of the pushing component cooperating with the piston and pushing the piston to move in Embodiment 1 of the present invention.

[0064] like Figure 9 and Figure 10 As shown, the pushing component 43 rotates clockwise under the drive of the motor body 441. As the pushing component 43 rotates, the second pushing end 432 moves to the second pushing end 412 and abuts against the second pushing end 412. At this time, the pushing component 43 continues to rotate, and the second pushing end 432 makes an arc-shaped movement in a general direction of energy storage. The second pushing end 412 applies an arc-shaped pushing force in a general direction of energy storage to the piston 41. Under the action of this pushing force, the piston 41 can move along the guide rod 422 in the direction of energy storage and compress the force supply spring 42 to store energy.

[0065] The first stage of energy storage is completed when the second pushing end 432 rotates to its maximum stroke in the energy storage direction. At this time, the pushing component 43 continues to rotate, and the second pushing end 432 rotates accordingly and disengages from the second abutting end 412. Simultaneously, the first pushing end 431 rotates to the first abutting end 411 and abuts against it. Subsequently, the first pushing end 431 pushes the piston 41 to move further in the energy storage direction in the same manner until the first pushing end 431 rotates to its maximum stroke in the energy storage direction, completing the second stage of energy storage, thus completing the entire spring energy storage process.

[0066] After the second stage of energy storage is completed, nail firing can begin. During nail firing, the motor body 441 drives the pusher component 43 to continue rotating. The first pusher end 431 rotates accordingly and disengages from the first abutment end 411. At this time, both the first pusher end 431 and the second pusher end 432 are outside the movement path of the piston 41. Therefore, under the action of the force spring 42, the piston 41 can move towards the nail firing direction until the firing pin 49 strikes the nail, causing the nail to be fired, thus completing the nail firing process. During the first or second stage of energy storage, due to the one-way bearing, the crank 430 will not rotate in the opposite direction under the force of the piston 41, thus preventing accidental nail firing.

[0067] The motor body 441 is used to drive the push member 43 to rotate, which in turn pushes the piston 41 to move, causing the force spring 42 to be compressed and stored, and finally the piston 41 is pushed out by the elastic force of the force spring 42.

[0068] Figure 11 This is a schematic diagram of the stroke analysis formed by the interaction between the pushing component and the piston pushing end in Embodiment 1 of the present invention.

[0069] Figure 12 This is a schematic diagram illustrating the stroke analysis formed by the interaction between the control group's pushing component and the piston's pushing end.

[0070] In this embodiment, both the first pushing end 431 and the second pushing end 432 are cylindrical, and the outer diameter of the second pushing end 432 is set to be smaller than the outer diameter of the first pushing end 431. The two outer diameters are not equal. This design, compared to designing them with equal outer diameters, can increase the piston stroke. The inventors conducted the following reference experiment:

[0071] like Figure 11 As shown, in this embodiment, the outer diameter of the first pushing end 431 is 18mm (radius is 9mm), the outer diameter of the second pushing end 432 is 14mm (radius is 7mm), the distance between the first pushing end 411 and the second pushing end 412 of the piston is 35mm, and the working stroke that can be achieved in the experiment is 81.5mm.

[0072] like Figure 12As shown, as a control group in this embodiment, the outer diameter of the first pushing end 431 and the second pushing end 432 are both 14mm (radius 7mm), the distance between the first pushing end 411 and the second pushing end 412 of the piston is 35mm, and the working stroke that can be achieved in the experiment is 79.5mm, which is significantly smaller than the stroke that can be achieved in this embodiment.

[0073] The calculation method resulting from the above work is as follows:

[0074] The working stroke is S, the distance between the first and second pushing ends of the piston is L, and the included angle between the first pushing end 431 and the second pushing end 432 is n (i.e., the included angle between the first crank arm 4301 and the second pushing end 432). The formula for calculating the arc length swept by the first pushing end 431 and the second pushing end 432 when rotating is: l = nπR / 180°. When the first pushing end 431 and the second pushing end 432 have the same diameter (both with radius R), the piston working stroke is S = L + l = L + (nπR / 180°). When the first pushing end 431 and the second pushing end 432 have unequal diameters (radii R1 and R2 respectively), S = L + l + (R1 - R2). Obviously, when the diameters are unequal, the piston working stroke is (R1 - R2) longer than when the diameters are equal. In other words, without changing the length of the piston's pushing end, the outer diameter of the pushing end is adjusted to obtain the maximum working stroke. The larger the working stroke, the greater the compression of the force spring 42, thus generating more energy and enabling the nail to be fired more powerfully and quickly. At the same time, since the nail gun structure needs to be compact, the design length of the nail gun should be minimized, which also facilitates operation, packaging, and transportation.

[0075] like Figure 2 As shown, the nail drive control mechanism 40 also includes a control component, which includes a main switch 46 and a safety switch 47. The main switch 46 and the safety switch 47 are connected in series and connected to the lithium battery 60 and the motor body 441. When the main switch 46 and the safety switch 47 have electrical signals at the same time, the motor body 441 can be controlled to start running.

[0076] The main switch 46 is a push-button switch, and its specific structure can adopt the structure of existing technology. It has a pressing part 461 and a main switch element 462. When the pressing part 461 is pressed, the main switch element 462 can generate a corresponding start electrical signal. The safety switch 47 is a linkage switch, which has a toggle part 471 and a safety switch element 472. When the safety switch element 472 contacts the toggle part 471, it can generate an electrical signal. In this embodiment, both the main switch element 462 and the safety switch element 472 are microswitches. When both the main switch element 462 and the safety switch element 472 generate electrical signals, the motor body 441 runs, causing it to drive the pushing member 43 to rotate to complete the above-mentioned spring energy storage process.

[0077] Figure 13 This is a schematic diagram of the structure of the safety switch installed inside the housing according to Embodiment 1 of the present invention.

[0079] Figure 15 This is a schematic diagram of the structure of the paddle installed in the paddle holder according to an embodiment of the present invention.

[0080] Figure 16 This is an exploded view of the mounting structure of the paddle and paddle holder according to an embodiment of the present invention.

[0081] like Figures 13-16 As shown, the actuating part 471 of the safety switch 47 has a lever 4711, a lever 4712, and a lever seat 4713 for mounting the lever 4711. The lever 4711 is located on one side of the safety switch element 472 and is linked with it. The linkage method is as follows: an actuating point 4721 is provided on one side of the safety switch element 472, the lever 4711 is hook-shaped and is mounted on the lever seat 4713, and the lever 4711 has a contact plate 47111, an actuating plate 47112, and a connecting plate 47113 for connecting the contact plate 47111 and the actuating plate 47112. The contact plate 47111 is positioned facing the actuation point 4721 of the safety switch element 472 and is used to contact the actuation point 4721. When the actuation point 4721 contacts the contact plate 47111, the safety switch element generates an electrical signal. The outer end of the toggle plate 47112 extends into a toggle seat 4713 and is used to contact the lever 4712. The length of the contact plate 47111 is less than the length of the toggle plate 47112, and the difference in length between the two forms a gap. Under the push of the lever 4712, the toggle plate 47112 will move towards the toggle seat 4713, thereby moving the contact plate 47111 as well, and gradually separating it from the actuation point 4721. When the actuation point 4721 is in the gap, the safety switch element 472 will disconnect the electrical signal. In order to allow the paddle 4711 to reset, a spring seat 47131 is also provided on the paddle seat 4713. A paddle reset spring 47114 is provided at the inner end of the spring seat 47131 facing the paddle 4711. The paddle reset spring 47114 abuts against the connecting plate 47113 of the paddle 4711.

[0082] Figure 17 yes Figure 13 A magnified view of section B.

[0083] The lever 4712 is a long rod with one end bent, used to control the movement of the paddle 4711. Specifically, the lever 4712 includes a first actuating lever 47121 and a second actuating lever 47122. The end of the first actuating lever 47121 is located near the pushing end of the pushing member 43, and will collide (scratch) during the rotation of the pushing end. The end of the second actuating lever 47122 is located inside the paddle 4711. A pin 47123 is provided at the connecting section where the first actuating lever 47121 and the second actuating lever 47122 are connected. The rear cover plate 212 of the housing 20 has a protruding mounting part 2121 for mounting the pin 47123. The lever 4712 is rotatably mounted on the mounting part 2121 via the pin 47123. In this embodiment, the first actuating lever 47121 and the second actuating lever 47122 are staggered, meaning they are not collinear. The entire lever 4712 is Z-shaped, and the length of the first actuating lever 47121 is less than the length of the second actuating lever 47122. Using the lever principle, if the first actuating lever 47121 is scraped by the pushing end, the second actuating lever 47122 will rotate in the opposite direction to the first actuating lever 47121, thus contacting the paddle 4711 and pushing it. This staggered design allows the first actuating lever 47121 sufficient space to rotate and ensures that the second actuating lever 47122 achieves the required stroke when pushing the paddle 4711.

[0084] Figure 18 This is one of the schematic diagrams showing the installation position of the safety switch and crank assembly in Embodiment 1 of the present invention.

[0085] like Figure 18 As shown, at this time, the safety switch element 472 is in a state with an electrical signal, that is, the contact point 4721 is in contact with the contact plate 47111 of the lever. When the pushing end of the pushing member 43 rotates clockwise, once it scrapes against the first lever 47121, it will cause the first lever 47121 to rotate inward. According to the lever principle, the second lever 47122 will rotate outward, touch the lever plate 47112 of the lever 4711, and push the lever 4711 to move outward, thereby causing the contact plate 47111 to leave the contact point 4721. At this time, the safety switch element 472 disconnects the electrical signal, and the drive motor also stops working immediately.

[0086] Since a toggle return spring 47114 is provided between one side of the toggle 4711 and the toggle seat, when there is no contact between the pushing end and the first toggle end 47121, the toggle return spring 47114 pushes the toggle 4711 inward to reset it, and the first toggle lever 47121 and the second toggle lever 47122 also reset in succession. The outer side of the first toggle lever 47121 may be provided with an inclined guide surface, which makes it easier for the pushing end to collide with the first toggle lever 47121 when rotating.

[0087] Figure 19 This is the second schematic diagram of the installation position of the safety switch and crank assembly in Embodiment 1 of the present invention.

[0088] The nail drive control mechanism 40 also includes a crank assembly 50, which is used to actuate the paddle 4711 in conjunction with the safety switch element 472. The crank assembly 50 has an outer crank 51 and an inner crank 52, as shown... Figure 1 and Figure 2 As shown, the outer end of the outer curved rod 51 extends out of the housing 20 and is mounted on the nozzle cover plate 33 of the nozzle mechanism via a pressure plate 53, with the outer end protruding from the nozzle mechanism. The inner end of the outer curved rod 51 is inserted into the housing 20 and linked with the inner curved rod 52. Figure 18 and Figure 19 As shown, the inner curved rod 52 has a short side 521 and a long side 522 arranged perpendicularly to each other. The outer side of the short side 521 contacts the inner end of the outer curved rod 51. The long side 522 extends to the vicinity of the paddle seat 4713 and bends at the end toward the paddle seat 4713 to form a contact section 5221. The paddle seat 4713 is provided with a socket 47132. The end of the contact section 5221 is inserted into the socket 47132 so that the contact section 5221 is connected to the paddle seat 4713.

[0089] The linkage between the crank assembly and the safety switch element 472 is as follows:

[0090] When using the nail gun, first align the nozzle mechanism located at the front with the target area to be nailed. Since the outer end of the outer curved rod 51 protrudes from the nozzle mechanism, when the outer end touches the target area, it will generate a reaction force on the outer curved rod 51, causing it to move towards the nail gun. The inner end of the outer curved rod 51 will touch the short side 521 of the inner curved rod 52, thereby pushing the inner curved rod 52 inward. During the movement, the outer curved rod 51 will also move the paddle seat 4713 towards the safety switch. When element 472 moves, the contact plate 47111 on the paddle 4711 in the paddle holder 4713 comes into contact with the contact point 4721 of the safety switch element 472 and presses it, causing the safety switch element 472 to generate an electrical signal. Then, the user presses down the pressing part 461, triggering the main switch element 462 to open and generate an electrical signal. When both switch elements are in the open state, the motor body 441 starts, the force spring begins to store energy, and then the nail is driven out to realize nail shooting.

[0091] like Figure 19 As shown, a crank return spring 55 is provided between the short side 521 of the inner crank 52 and the cylinder head seat 48 to cause the crank assembly to reset. After the nail is fired, when the user removes the nail gun and the outer end of the outer crank 51 separates from the target part, the crank return spring 55 will drive the inner crank 52 and the outer crank 51 to reset. A protective cover 54 is also provided at the outer end of the outer crank 51. By having the protective cover 54 in contact with the target part, wear on the outer end of the outer crank 51 can be reduced, extending the service life of the outer crank.

[0092] The working principle of this embodiment:

[0093] When using the nail gun, first align the nozzle mechanism at the front with the target area to be nailed. The outer crank rod 51 is pushed, causing the inner crank rod to move the paddle seat towards the safety switch element 472, triggering the safety switch element 472 to generate an electrical signal. Then, the user activates the main switch element 462, generating an electrical signal. Since both the main switch and the safety switch generate electrical signals, the motor body 441 starts, driving the pushing component 43 to rotate. During rotation, the pushing component 43 causes the piston 41 to move towards the force spring 42, compressing the force spring 42 and gradually performing the first and second stages of energy storage. After the second stage of energy storage is completed, nailing can begin. During nail firing, the motor body 441 drives the pusher component 43 to continue rotating. The first pusher end 431 rotates accordingly and disengages from the first abutment end 411. At this time, both the first pusher end 431 and the second pusher end 432 are outside the movement path of the piston 41. Therefore, the piston 41 can move towards the nail firing direction under the force of the power spring 42 until the firing pin 49 hits the nail, causing the nail to be fired and completing the nail firing process. At the same time, since the outer edge of the first pusher end 431 protrudes from the outer end of the first crank arm 4311, it will rub against the first actuating lever 47121 during rotation, causing the first actuating lever 47121 to rotate inward, causing the second actuating lever 47122 to move outward and hit the paddle 4711, causing the paddle 4711 to move outward, thereby causing the contact plate 47111 to leave the contact point 4721. At this time, the contact point 4721 is exactly aligned with the opening slot 47112, the safety switch element 472 is disconnected, and the motor stops rotating.

[0094] <Example 2>

[0095] Figure 20 This is a schematic diagram of the structure of the safety switch installed inside the housing in Embodiment 2 of the present invention.

[0096] Figure 21 This is a schematic diagram of the installation position of the safety switch and crank assembly in Embodiment 2 of the present invention.

[0097] This embodiment is basically the same as Embodiment 1 above, except for the structure of the actuating part and the crank assembly in the control component. Specifically, as follows: Figure 20As shown, the toggle part 471' of the safety switch 47' has a toggle piece 4711' and a toggle lever 4712'. The toggle piece 4711' is located on one side of the safety switch element 472' and is linked with it. The linkage method is as follows: a switch protrusion 4721' is provided on one side of the safety switch element 472', and a trigger end 47111' is provided on the toggle piece 47111'. When the trigger end 47111' touches the switch protrusion 4721', the safety switch element 472' is triggered to open and generate an electrical signal. An opening slot 47112' is provided on the side of the trigger end 47111'. When the toggle piece 4711' moves, the trigger end 47111' moves away from the switch protrusion 4721', and the switch protrusion 4721' aligns with the opening slot 47112', the safety switch element 472' disconnects the electrical signal.

[0098] like Figure 21 As shown, the actuating lever 4712' is a long rod with one end bent, used to control the movement of the actuating piece 4711'. Specifically, the actuating lever 4712' includes a first actuating end 47121' and a second actuating end 47122'. The end of the first actuating end 47121' is located close to the pushing end of the pushing member 43', and will collide (scratch) during the rotation of the pushing end; the end of the second actuating end 47122' is located inside the actuating piece 4711'. A pin 47123' is provided at the connecting section where the first actuating end 47121' and the second actuating end 47122' are connected. The rear cover plate 212' of the housing has a protruding mounting part for mounting the pin 47123'. The actuating lever 4712' is rotatably mounted on the mounting part through the pin 47123'. (The structure of the actuating lever and its mounting structure with the housing are the same as in Embodiment 1).

[0099] like Figure 21 As shown, when the pushing end of the pushing member 43' rotates clockwise, if it scrapes against the first toggle end 47121', it will cause the first toggle end 47121' to rotate inward, causing the second toggle end 47122' to move outward and touch the toggle piece 4711', causing the toggle piece 4711' to move outward, thereby causing the trigger end 47111' to leave the switch protrusion 4721' and disconnect the safety switch element 472'. A toggle return spring 47113' is provided between the outer side of the toggle piece 4711' and the housing. When there is no contact between the pushing end and the first toggle end 47121', the toggle return spring 47113' pushes the toggle piece 4711' inward to reset, and the first toggle end 47121' and the second toggle end 47122' also reset in succession. An inclined guide surface 471211' is provided on the outer side of the first actuating end 47121', which facilitates the collision between the pushing end and the first actuating end 47121' when rotating.

[0100] The nail drive mechanism 40 also includes a crank assembly 50', which is used to actuate the actuating piece 4711' and the safety switch element 472'. The crank assembly 50' has an outer crank 51' and an inner crank 52'. The outer end of the outer crank 51' extends out of the housing 20 and protrudes from the nozzle mechanism. The inner end of the outer crank 51' is linked to the inner crank 52'. Figure 21 As shown, the inner curved rod 52' has a short side 521' and a long side 522' arranged perpendicularly to each other. The outer side of the short side 521' contacts the inner end of the outer curved rod 51', and the long side 522' extends to the vicinity of the actuating piece 4711' and bends at its end toward the actuating piece 4711' to form a contact section 5221'. A contact plate 47114' is provided on the actuating piece 4711' near the contact section 5221', and an opening slot 47112' is located between the contact plate 47114' and the trigger end 47111'. A crank rod return spring 55' is provided on one side of the contact section 5221'.

[0101] The linkage between the crank assembly and the safety switch element 472' is as follows:

[0102] When using a nail gun, first align the nozzle mechanism located at the front with the target area to be nailed. Since the outer end of the outer curved rod 51' protrudes from the nozzle mechanism, when the outer end touches the target area, it generates a reaction force, causing the outer curved rod 51' to move towards the nail gun. The inner end of the outer curved rod 51' will then contact the short side 521' of the inner curved rod 52', thus pushing the inner curved rod 52' inward. During this movement, the outer curved rod 51' can facilitate the contact... Contact segment 5221' contacts the contact plate 47114' on the toggle piece 4711', pressing the toggle piece 4711' towards the safety switch element 472', causing the safety switch element 472' to open and generate an electrical signal. Then, the user presses the pressing part 461', triggering the main switch element 462' to open and generate an electrical signal. When both switch elements are in the open state, the motor starts, the force spring begins to store energy, and then the nail is driven out, realizing nail firing. After nail firing is completed, when the outer end of the outer curved rod 51' separates from the target part, the curved rod return spring 55' will drive the inner curved rod 52' and the outer curved rod 51' to return to their original positions. Similar to Embodiment 1, the outer end of the outer curved rod 51' is also provided with a protective cover 54'. By having the protective cover 54' contact the target part, the wear of the outer end of the outer curved rod 51' can be reduced, extending the service life of the outer curved rod.

[0103] Functions and effects of the embodiments

[0104] According to the nail drive control mechanism and nail gun of the above embodiment, since the toggle part of the safety switch has a toggle piece, a toggle lever and a toggle piece seat, the safety switch is turned on and off by means of mutual linkage between the toggle piece, the toggle lever, the toggle piece seat and the push component. This is a mechanical structure control method, which does not require a separate controller, thereby saving costs and making the operation more stable.

[0105] According to the above embodiment of the nail drive control mechanism and nail gun, since a pushing member 43 is provided, and the pushing member 43 directly cooperates with the piston 41 to push the piston 41 toward the force spring 42, thereby compressing and storing energy in the force spring 42, and the pushing member 43 has no direct contact with the firing pin 49, the movement of the piston 41 is avoided due to contact with the firing pin 49, making the entire energy storage process smoother and more stable.

[0106] In addition, the pushing member 43 has a pushing end facing the piston 41. The piston is moved by the pushing end contacting the abutting end on the piston 41 during the rotation process. The pushing end has a first pushing end 431 and a second pushing end 432, which can perform the first stage of energy storage and the second stage of energy storage respectively, so as to maximize the energy storage capacity of the force spring 42. At the same time, the outer diameters of the first pushing end 431 and the second pushing end 432 are different, so that the outer diameter of the pushing end can be adjusted to obtain the maximum working stroke of the piston 41 without changing the length of the abutting end of the piston 41. The larger the working stroke, the greater the amount of compression of the force spring 42, thereby obtaining more energy and firing the nail more powerfully and quickly.

[0107] In this embodiment, the pusher component 43 is designed in the shape of a crank 430, which is lighter than the disc and other structures in the prior art. This not only saves materials but also reduces energy consumption and improves the transmission effect.

[0108] The nail-driving control mechanism provided in this embodiment also includes a control component, which comprises a main switch 46 and a safety switch 47. These two switches are connected in series and to the drive motor. Therefore, the motor body 441 of the nail gun 10 can be directly controlled based on the nail-driving electrical signal and the safety electrical signal generated by the main switch 46 and the safety switch 47. Since the main switch 46 and the safety switch 47 are connected in series, the motor body 441 can only be started when both the nail-driving electrical signal and the safety electrical signal are received simultaneously and both signals are valid, thereby performing nail-driving. Because the nail-driving control mechanism adopts a double-switch, double-safety design, safety during the nail-driving process is also ensured.

[0109] Furthermore, through the nail drive control mechanism of this embodiment, the nail gun 10 can activate the safety switch by means of the crank assembly when it touches the target position, and automatically start to store energy when the main switch 46 is pressed, that is, when it is started, and maintain the state of complete energy storage. Therefore, the user only needs to press a switch to directly dispense the nail, which is very convenient to operate.

[0110] The above embodiments are only used to illustrate specific implementations of the present invention, and the present invention is not limited to the scope of the description of the above embodiments.

[0111] For example, during implementation, the unidirectional rotation component at the output end of the drive motor can be replaced with a unidirectional bearing instead of a ratchet and pawl structure to achieve the same purpose.

After the first stage of energy storage is completed, the second pushing end abuts against the second pushing end and pushes the second pushing end, causing the piston to move toward the force-supplying spring, thereby enabling the force-supplying spring to perform the second stage of energy storage.

9. The nail-driving control mechanism according to claim 8, characterized in that, in, The drive motor includes: The motor body has an output shaft. A speed reducer, mounted on the output shaft, has an output end for mounting the push member. The unidirectional rotating component has: A ratchet, fitted onto the output end, has several ratchet teeth. A pawl, disposed on the side of the ratchet, is used to insert into the ratchet teeth and engage with them to allow the ratchet to rotate in one direction; and The pawl spring is mounted on the reducer at one end and rests against the pawl at the other end.

10. A nail gun, characterized in that, At least including: The housing has an internal mounting cavity. The nozzle mechanism is mounted on the front end of the housing, and The nail-driving control mechanism is installed inside the mounting cavity. The nail drive control mechanism is the nail drive control mechanism as described in any one of claims 1-9.
