Description

Technical Field

[0001] This invention belongs to the field of fastening tool technology, specifically relating to an energy storage drive mechanism for a lithium-ion nail gun and a lithium-ion nail gun. Background Technology

[0002] A nail gun is a fastening tool, primarily used in construction. Based on the power source, nail guns are categorized into lithium-ion nail guns and pneumatic nail guns. Lithium-ion nail guns use a lithium battery to power a control system that drives a motor and transmission mechanism to push a piston. The piston compresses a spring to store energy. During nail firing, the spring drives the piston, which in turn moves a firing pin mounted on the piston to strike and eject the nail. Pneumatic nail guns, on the other hand, have a cylinder inside the gun housing. Inside the cylinder is a piston, which divides the cylinder's interior into an inlet chamber and an outlet chamber. The inlet chamber requires a separate air compressor to supply air. The compressor fills the inlet chamber with high-pressure gas, which drives the piston, which in turn moves the firing pin to strike and eject the nail. The aforementioned nail guns that use springs to store energy and drive nailing are not suitable for objects with high hardness due to the limitations of spring force; while the aforementioned pneumatic nail guns are inconvenient to carry in actual use because they require a separate air compressor to provide gas.

[0013] Invention Function and Effect

[0014] According to the energy storage drive mechanism and lithium-ion nail gun of the present invention, since the energy storage component is provided with a gas chamber for accommodating and storing gas, the energy storage component of the nail gun itself has a gas storage function, eliminating the need to connect a compressor to provide gas during the operation of the nail gun, simplifying the structure and making it more convenient to carry and use. In addition, since the volume of the gas chamber is V1 when the striking component is in the low energy storage position and V2 when the striking component is in the high energy storage position, the difference between the gas chamber volume at the high energy storage position and the gas chamber volume at the low energy storage position, V1-V2, is approximately equal to or equal to 1 / 3*V2. This difference is actually the volume of the area that the striking component moves from the low energy storage position to the high energy storage position inside the inner cylinder. This volume accounts for a large proportion of the entire energy storage component. That is, by increasing the volume of the inner cylinder, the energy consumption of the entire gun body is reduced during operation, and the requirements for the motor and battery of the lithium-ion nail gun are reduced, realizing the miniaturization and weight reduction of the lithium-ion nail gun, and thus reducing the cost.

Detailed Implementation

[0036] To make the technical means, creative features, objectives and effects of the present invention easy to understand, the following describes in detail the energy storage drive mechanism for the lithium-ion nail gun and the lithium-ion nail gun of the present invention with reference to the embodiments and accompanying drawings.

[0037] <Example>

[0038] This embodiment provides a nail gun with an energy storage component for nail guns, which makes it easier to operate and can improve safety and nailing effect.

[0039] Figure 1 This is a structural diagram of the lithium-ion battery nail gun in an embodiment of the present invention.

[0040] Figure 2 This is a structural diagram of the lithium-ion battery nail gun after part of its casing has been removed, according to an embodiment of the present invention.

[0041] The lithium-ion battery nail gun 10 of this embodiment includes a housing 20, a nail storage device 30, a driving device 40 for firing the nails, and a control device 50 for controlling the driving device. Figure 1 and Figure 2 As shown, the housing 20 includes a housing 21 disposed on the outer side, and a nail storage device 30 disposed at the front end of the housing 21, storing nails. The control device 50 includes components such as a power supply (lithium battery), control board, wiring, and switches (not fully shown in the figures), all mounted inside and on the surface of the housing 21. The housing 21 not only houses the internal components such as the drive device 40 and the control device 50, but also protects these internal components.

[0042] Figure 3 This is a structural diagram of the driving device in an embodiment of the present invention.

[0043] Figure 4 This is a cross-sectional view of the driving device in an embodiment of the present invention.

[0044] The drive unit 40 is located inside the housing 21 and acts on the nail to drive it out. Figures 3-4 As shown, the drive device 40 includes an energy storage drive mechanism that directly contacts the nail and is used to drive the nail out. The energy storage drive mechanism has a striking component 41, an energy storage component 42 for providing power to the striking component 41, and a drive component 43. The striking component 41 has a striking direction for driving the nail out. The energy storage component 42 can drive the striking component 41 to move forward along the striking direction to drive the nail out. The drive component 43 drives the striking component 41 to move backward along the striking direction, thereby triggering the energy storage component 42 to store energy.

[0045] The striking assembly 41 includes a firing pin component 411 and a piston component 412. The inner end of the firing pin component 411 is inserted into the piston component 412, and the piston component 412 is movably disposed inside the energy storage assembly 42. The outer end of the firing pin component 411 extends out of the energy storage assembly 42, which is used to push the nail and fire the nail along the striking direction.

[0047] Figure 6 This is a cross-sectional view of the driving device when the striking component is located at the high energy storage position in an embodiment of the present invention.

[0048] Figure 7This is a cross-sectional view of the energy storage component in an embodiment of the present invention.

[0049] like Figure 4 As shown, the energy storage component 42 includes an energy storage component 45, an inflation component 46, and a pressure relief component 47. The energy storage component 45 has an outer cylinder 451 and an inner cylinder 452. The outer cylinder 451 includes an outer cylinder body 4511 and a rear cover 4512 covering the rear end of the outer cylinder body 4511. The rear cover 4512 is detachable. The inner side of the outer cylinder body 4511 is hollow. The inner cylinder 452 is also installed inside the outer cylinder body 4511. An air chamber 453 is formed between the inner cylinder body 452 and the outer cylinder 451. The inner cylinder 452 has a long cylindrical ring structure. A striking component 41 is installed inside the inner cylinder 452. The outer periphery of the piston part 412 of the striking component 41 is in close contact with the inner wall of the inner cylinder 452. A second sealing element, which is a sealing ring 413, is pressed between the piston part 412 and the inner wall of the inner cylinder 452. A striking pin component 411 is fixed on the piston part 412. The front end of the striking pin component 411 extends out of the front end of the inner cylinder 452 and the outer cylinder body 4511 for cooperation with the transmission component.

[0050] The striking assembly 41 is movably disposed inside the inner cylinder 452 via the piston portion 412, and has a low energy storage position and a high energy storage position, such as... Figure 5 As shown, the striking component is currently in the low energy storage position, and the volume of the air chamber 453 is V1, as... Figure 6 As shown, the striking component is currently in the high energy storage position, and the volume of the air chamber 453 is V2. The air chamber 453 includes the volume of the inner cylinder 452 and the volume between the outer cylinder 451 and the inner cylinder, that is, the space formed between the piston portion 412 of the striking component and the outer cylinder 451. The low energy storage position is actually the state when the striking component is located at the front end of the inner cylinder 452 and is not driven by the driving component; while the high energy storage position is when the striking component is located at the rear end of the inner cylinder 452, and at this time the striking component is driven to its extreme position by the driving component. The difference between V1 and V2 is actually the volume of the inner cylinder 452 swept by the piston portion 412 when the striking component moves from the low energy storage position to the high energy storage position (e.g., V1-V2). Figure 7 The gray area in the middle, Figure 7 In the diagram, the dashed line represents the position of piston 412 when it is in the low energy storage position, and the solid line represents the position of piston 412 when it is in the high energy storage position.

[0051] The volume of V1-V2 depends on the size of the inner cylinder 452 and the distance that the piston part 412 moves driven by the drive assembly. In this embodiment, V1-V2 is approximately equal to or equal to 1 / 3*V2. The volume ratio of the inner cylinder 452 is relatively large, resulting in low energy consumption and low requirements for the motor and battery.

[0052] In this embodiment, V1 is 920ml and V2 is 690ml. During the research and development process, the inventors conducted multiple experiments under the same temperature and environment, as detailed below:

[0053] (1) When the striking component is in the low energy storage position,

[0054] When the gas pressure is 0.5 MPa, the pressure is 1100 N and the kinetic energy is about 65 J.

[0055] When the gas pressure is 0.6 MPa, the pressure is 1350 N and the kinetic energy is about 80 J.

[0056] When the gas pressure is 0.7 MPa, the pressure is 1560 N and the kinetic energy is about 95 J.

[0057] (2) When the striking component is in the high energy storage position,

[0058] When the gas pressure is 0.5 MPa, the pressure is 900 N; the kinetic energy is approximately 50 J.

[0059] When the gas pressure is 0.6 MPa, the pressure is 1050 N; the kinetic energy is approximately 60 J.

[0060] When the gas pressure is 0.7 MPa, the pressure is 1200 N; the kinetic energy is approximately 72 J.

[0061] like Figure 4 As shown, the piston portion 412 and the sealing ring 413 divide the interior of the inner cylinder 452 into two separate parts: a first chamber 4521 and a second chamber 4522. The volumes of these two parts change as the piston portion 412 moves. The second chamber 4522 communicates with the air chamber 453, while the first chamber 4521 is separate from the second chamber 4522 and communicates with the outside. The front end of the inner cylinder 452 has an internal through hole 4523 connecting the first chamber 4521 to the outside. In this embodiment, the rear cover 4512 is designed to be detachable, facilitating the disassembly of the outer cylinder to replace or repair the internal striking assembly 41. To create a sealed space inside the air chamber, a first sealing element 4513 is provided at the connection between the rear cover 4512 and the outer cylinder body 4511. This enhances the tightness of the connection between the rear cover 4512 and the outer cylinder body 4511, preventing air leakage from the air chamber 453. In this embodiment, the first sealing element 4513 is a sealing ring (such as...). Figure 8 (As shown).

[0062] The air chamber 453 is filled with air or nitrogen. Since the striking component 41 is installed inside the inner cylinder 452, when the striking pin component 411 is driven to move by the transmission component 431, the piston part 412 will move towards the second chamber 4522. The volume of the second chamber 4522 gradually decreases, thereby compressing the gas in the air chamber 453, causing the air pressure inside the air chamber to gradually increase, thus accumulating energy. The first chamber 4521 is at its maximum volume, which is the value of V1-V2.

[0063] Figure 8 yes Figure 4 A magnified view of section B.

[0064] To facilitate the replenishment of gas in the air chamber 453, an inflation component 46 is provided at one end of the outer cylinder body 4511 near the rear cover 4512. For example... Figure 4 and Figure 8 As shown, an air inlet 4514 is provided on the outer cylinder body 4511 near the rear cover 4512, and an air intake channel 4531 connecting the air chamber 453 and the air inlet 4514 is provided on the outer cylinder body 4511 on one side of the air inlet 4514. The inflation component 46 is an inflation nozzle with an inflation channel 461 in the middle. The inner end of the inflation nozzle is inserted into the air inlet 4514, and the outer end extends out of the outer cylinder body 4511 and is exposed on the outside, so that the user can inflate the inflation nozzle.

[0065] Figure 9 yes Figure 4 A magnified view of a portion of point C.

[0066] A pressure relief component 47 is provided on one side of the front end of the outer cylinder body 4511. In this embodiment, the pressure relief component 47 is an automatic pressure relief valve. When the air pressure in the air chamber 453 gradually increases and reaches a set critical value, the automatic pressure relief valve will automatically open to relieve pressure in the air chamber 453, so that the air pressure in the air chamber 453 is always kept within the critical value, thereby ensuring the safety of the outer cylinder body 4511. In addition, the outer end of the pressure relief component 47 is exposed on the outside of the outer cylinder body 4511. When the user needs to disassemble and inspect the outer cylinder body, the pressure relief valve can be opened manually first to release the gas inside the air chamber 453 before disassembly, avoiding accidental firing of the firing pin component and injuring the user due to excessive air pressure inside the air chamber, thus enhancing the safety of the product.

[0067] Specifically, such as Figure 9As shown, a pressure relief port 4515 is provided on one side of the front end of the outer cylinder body 4511, and a pressure relief channel 4532 connecting the pressure relief port 4515 and the air chamber 453 is provided on the outer cylinder body 4511. The automatic pressure relief valve has a pressure relief valve body 471, a pressure relief valve core 472, and a pressure relief spring 473. One end of the pressure relief valve body 471 is fixedly installed in the pressure relief port 4515, and the other end extends out and is exposed on the outside of the outer cylinder body 4511. A pressure relief cavity 474 communicating with the pressure relief port 4514 is provided in the middle of the pressure relief valve body 471. A pressure relief hole 475 connecting the pressure relief cavity 474 and the outside is provided on the side of the pressure relief valve body 471. The pressure relief valve core 472 is movably disposed in the pressure relief cavity 474 by means of the pressure relief spring 473. The side wall of the pressure relief cavity 474 is formed with a limiting and blocking surface 4741 that cooperates with the pressure relief valve core 472. When the automatic pressure relief valve is closed, the pressure relief valve core 472, under the action of the pressure relief spring 473, blocks the connection between the pressure relief cavity 474 and the pressure relief port 4515. At this time, the pressure relief valve core 472 is tightly pressed against the limiting blocking surface 4741, and the gas in the air chamber 453 cannot be discharged. When the air pressure in the air chamber 453 gradually increases and exceeds the preset value, the gas will enter the pressure relief cavity 474 through the pressure relief channel 4532 and the pressure relief port 4515 and gradually push the pressure relief valve core 472. When the pressure relief valve core 472 is pushed away from the limiting blocking surface 4741 to form a gap, the gas can pass through the gap and be discharged from the pressure relief hole 475, thereby relieving the pressure inside the air chamber 453. When the air pressure in the air chamber 453 drops to the preset value, under the action of the pressure relief spring 473, the pressure relief valve core 472 will be pushed back to its original position, making it tightly pressed against the limiting blocking surface 4741. The automatic pressure relief valve does not require manual activation during operation and can automatically open according to changes inside the air chamber 453, thus protecting the air chamber 453.

[0068] Figure 10 yes Figure 4 A magnified view of a portion of point D.

[0069] like Figure 4 As shown, the front end of the inner cylinder 452 is fixedly connected to the front end of the outer cylinder 451, and a buffer pad 454 is provided at the connection. The buffer pad 454 has a through hole 4541 in the middle for the front end of the impact pin component to extend out. The inner end face of the buffer pad 454 is used to buffer the piston part 412. The piston part 412 is pushed forward by the air pressure in the air chamber 453 (impact direction). The piston part 412 can move until it is blocked by the buffer pad 454. The buffer pad 454 can block and buffer the piston part 412, preventing it from directly impacting the inner side of the outer cylinder body and protecting the piston part 412.

[0070] like Figure 9 and Figure 10As shown, the specific installation structure of the buffer pad 454 is as follows: the inner cylinder 452 is a sleeve structure with a circular cross-section; the outer periphery of the buffer pad 454 is formed with a mounting protrusion 4542; the inner side of the front end of the outer cylinder body 4511 forms a limiting surface 4516 and a mounting retaining ring 4517; the front end of the buffer pad 454 abuts against the limiting surface 4516 (e.g., ...). Figure 4 As shown), the front end face of the inner cylinder 452 abuts against the mounting protrusion 4542 and the mounting retaining ring 4517, thereby achieving the connection between the buffer pad 454, the inner cylinder 452, and the outer cylinder body 4511. Figure 12 As shown, a third sealing element 455 is provided between the outer periphery of the inner cylinder body 452 and the inner wall of the outer cylinder body 4511. The third sealing element 455 consists of two sealing rings. An outer through hole 4518 is provided at the front end of the outer cylinder body 4511 outside the inner through hole 4523. The inner through hole 4523 and the outer through hole 4518 are connected, thereby connecting the first cavity 4521 to the outside. In the transverse cross-section, the inner through hole 4523 and the outer through hole 4518 are located in front of the third sealing element, and the air cavity 453 is located behind the third sealing element. The third sealing element 455 not only strengthens the connection tightness but also separates the air cavity 453 from the first cavity 4521, forming two independent spaces and preventing the air cavity 453 from being affected by external air pressure due to its connection with the outside.

[0071] Figure 11 This is an exploded view of the drive device portion of an embodiment of the present invention.

[0072] like Figure 11 As shown, the drive assembly 43 has a transmission component 431 and a limiting component 432. The transmission component 431 is used to cooperate with the firing pin component 411 and drive the firing pin component 411 to move in the opposite direction along the striking direction. The limiting component 432 is used to cooperate with the transmission component 431 to limit the movement of the firing pin component 411. The transmission component 431 is provided with a limiting part 433 that cooperates with the limiting component 432.

[0074] Figure 13 yes Figure 3 A magnified view of part A.

[0075] like Figure 12As shown, the drive assembly 43 also has a drive source for providing power to the transmission component 431 and a reducer. In this embodiment, the drive source is a motor 434 (powered by a lithium battery). A reducer 435 is mounted on the output shaft of the motor 434. The reducer 435 is a three-stage reducer, which has a first reducer 4351, a second reducer 4352 and a third reducer 4353 connected in series. The transmission ratio of the entire reducer can reach 1:120.

[0076] Figure 14 This is a schematic diagram of the cooperative structure of the driving component and the striking component in an embodiment of the present invention.

[0077] Figure 15 This is one of the cross-sectional views of the cooperative structure of the driving component and the striking component in the embodiments of the present invention.

[0078] Figure 16 This is the second cross-sectional view of the structure of the drive component and the striking component in an embodiment of the present invention.

[0079] like Figure 14 and Figure 15 As shown, the firing pin component 411 has several toothed blocks 4111 on one side, with adjacent toothed blocks 4111 forming toothed grooves 4112. The transmission component 431 includes a rotating part 4311 and a mating part. The rotating part 4311 is an annular structure with an "I"-shaped cross-section and a mounting hole 43111 in the middle. Through this mounting hole 43111, the rotating part 4311 can be mounted onto the output shaft 51 of the control motor (not shown in the figure) of the nail gun, so that the rotating part 4311 rotates under the drive of the control motor. The mating part consists of several toothed pins 4312 arranged on the rotating part 4311. The toothed pins 4312 are embedded in the toothed grooves 4112 on the firing pin component 411 (e.g., ...). Figure 15 As shown), this allows for the engagement between the transmission component 431 and the striking pin component 411. When the rotating part 4311 rotates under the drive of the control motor, the toothed pin 4312 engages in the toothed groove 4112, thereby driving the striking pin component 411 to move laterally. Figure 14 As shown, when the toothed pin 4312 rotates counterclockwise following the rotating part 4311, it can drive the firing pin part 411 to move to the right (towards...). Figure 14 The arrow direction shown is the reference direction, and the arrow direction of the firing pin component is the opposite direction of the striking direction.

[0080] like Figure 15 and Figure 16 As shown, among the plurality of toothed pins 4312, there is at least one movable toothed pin 4312', and the rotating part 4311 is provided with an elongated movable hole 43112 for the movable toothed pin 4312' to move (e.g., Figure 11As shown), an elastic component is provided between the movable toothed pin 4312' and the rotating part 4311. This elastic component includes: a first spring 441, one end of which acts on the rotating part 4311, and the other end of which acts on the movable toothed pin 4312'. A receiving cavity for mounting the first spring 441 is provided within the rotating part 4311. The elastic component also includes a top block 442 located between the first spring 441 and the movable toothed pin 4312'. The top block 442 has a limiting hole 4421 for inserting the first spring 441 or a limiting post for fitting the first spring 441 (in this embodiment). Figure 16 The middle part is the limiting hole 4421); the top block 442 has a working surface that contacts the movable toothed pin 4312' at one end facing the movable toothed pin 4312'.

[0081] Each toothed pin 4312 corresponds to a toothed groove 4112. In this embodiment, nine toothed pins 4312 are provided, with the movable toothed pin 4312' serving as the first toothed pin, used to embed into the first toothed groove 4112'. Making the first toothed pin movable ensures that the first toothed groove 4112' can be better embedded. For example, if the movable toothed pin 4312' happens to touch the toothed block 4111 during triggering, because the movable toothed pin 4312' is movable, the reaction force of the toothed block 4111 will push the movable toothed pin 4312' to make a slight movement within the movable hole 43112, and under the action of the first spring 441, embed it into the first toothed groove 4112' (e.g., ...). Figure 15 As shown), this ensures that the first toothed pin and the first toothed groove can properly engage, preventing jamming. When the toothed pin 4312 rotates continuously counter-clockwise following the rotating part 4311, each toothed pin gradually engages in its corresponding toothed groove, thereby causing the striking pin component 411 to gradually move to the right (as shown). Figure 16 (As shown). In the counterclockwise direction, the teeth from the first to the nth tooth are evenly distributed on the edge of the rotating part 4311, and there is a first gap of the same distance between two adjacent teeth 4312; in the clockwise direction, a second gap is formed between the first and nth teeth, and the second gap is larger than the first gap. When the rotating part 4311 moves to the second gap facing the firing pin component 411, since there are no teeth between the second gaps, the rotating part 4311 and the firing pin component 411 are in an empty tooth state. The firing pin component 411 in this state can be triggered by the energy storage component to move along the striking direction, thereby firing the nail.

[0082] like Figure 14As shown, the limiting part 433 is a ratchet coaxially arranged with the rotating part 4311. Both the ratchet and the rotating part 4311 are sleeved on the output shaft 51 of the control motor of the nail gun, and are fixedly connected together by a pin. Under the drive of the control motor, the ratchet and the rotating part 4311 rotate synchronously. The outer circumference of the ratchet is provided with several ratchet teeth 4331, and the limiting part 432 has a pawl 4321 that cooperates with the ratchet teeth 4331 for engaging between adjacent ratchet teeth. Figure 14 As shown, the distance between adjacent ratchet teeth 4331 is smaller than the width of the tooth groove 4112, making the pawl and ratchet teeth engage more tightly and securely, and less prone to disengagement. Compared to the prior art where the pawl directly engages with the tooth groove 4112, the above-mentioned ratchet-tooth engagement method in this embodiment is much tighter and more secure because the distance between the ratchet teeth 4331 is much smaller than the width of the tooth groove 4112, reducing the likelihood of ratchet disengagement as in the prior art. In practice, the limiting part 433 can also be a ratchet directly integrally set on the rotating part 4311 (i.e., the rotating part 4311 is made thicker, and the ratchet is directly set on the outer periphery of the upper part of the rotating part 4311; this implementation is not shown in the figure). This method ensures that the limiting part 433 and the rotating part rotate synchronously and reduces the number of parts, but it places higher demands on the machining process of the rotating part.

[0083] Figure 17 This is a structural diagram of the outer cylinder body in an embodiment of the present invention.

[0084] Figure 18 This is a structural cross-sectional view of the outer cylinder body in an embodiment of the present invention.

[0085] like Figure 17 As shown, the front end of the outer cylinder body 4511 is provided with a mounting portion 4519. The mounting portion 4519 is formed with a groove 4519a for mounting the transmission component. The groove 4519a has a shape adapted to the rotating part of the transmission component, namely, an annular shape. The mounting portion 4519 is provided with a mounting groove 4519b on one side of the groove 4519a. The pawl 4321 of the limiting component 432 is installed in the mounting groove 4519b. The side of the groove 4519a facing the mounting groove 4519b has a hole 4519c for one end of the pawl 4321 to pass through.

[0086] like Figure 9As shown, the pawl 4321 has a positioning end 4321a, a limiting end 4321b, and a connecting section 4321c. The positioning end 4321a is rotatably mounted in the mounting groove 4519b via a rotating shaft 4321d. The limiting end 4321b extends into the groove 4519a through a hole 4519c on the side wall of the groove 4519a and engages with the ratchet teeth 4331 on the ratchet wheel located in the groove 4519a. The connecting section 4321c connects the positioning end 4321a and the limiting end 4321b. A second spring 4322 is provided on one side of the connecting section 4321c. A positioning screw 4323 is inserted into the mounting part 4519 to provide support for one end of the second spring 4322. The two ends of the second spring 4322 abut against the positioning screw 4323 and the connecting section 4321c, respectively. Under the action of the second spring 4322, the limiting end 4321b of the pawl 4321 can better cooperate with the ratchet 4331, so that the limiting end 4321b is embedded in the ratchet 4331, preventing the ratchet from rotating in the opposite direction. At the same time, if Figure 17 As shown, the mounting part 4519 has positioning holes 4519d and 4519e corresponding to the rotating shaft 4321d and the positioning screw 4323, respectively, for mounting the rotating shaft 4321d and the positioning screw 4323. The engagement of the ratchet 4331 and the pawl 4321 can prevent the ratchet from rotating in the opposite direction. Since the ratchet and the rotating part are coaxially arranged, the rotating part can be prevented from rotating in the opposite direction, thereby preventing the firing pin component from being accidentally fired, and providing stronger safety.

[0087] Figure 19 This is a structural diagram of the inner cylinder in an embodiment of the present invention.

[0088] Figure 20 yes Figure 4 A magnified view of a portion at point E.

[0089] like Figure 4 As shown, the inner cylinder body 452 is installed inside the outer cylinder body 4511. The front end of the inner cylinder body 452 is connected to and locked to the inner wall of the outer cylinder body 4511 via a third seal 455. To ensure the inner cylinder body 452 is more stably positioned inside the outer cylinder body 4511, as shown... Figure 19 As shown, a convex ring 4524 is provided at the end of the inner cylinder 452 away from the third seal 455. A circular positioning ring 456 is provided on one side of the convex ring 4524, and an air hole 4561 for gas to pass through is provided on the positioning ring 456. Figure 20As shown, the inner circumference of the positioning ring 456 is fitted around the outer circumference of the inner cylinder body 452, and one side is abutted by the convex ring 4524. The outer circumference of the positioning ring 456 is blocked by the end face of the rear cover 4512 facing the outer cylinder body 4511, thereby limiting the positioning ring 456 between the rear cover 4512 and the convex ring 4524, enhancing the connection stability between the structures. The third seal 455 and the positioning ring 456 are located at the front and rear ends of the inner cylinder body 452, respectively, providing support for both ends of the inner cylinder body 452, allowing the inner cylinder body 452 to be more stably fixed inside the outer cylinder body 4511.

[0090] The working principle of this embodiment:

[0091] The control motor in the control device 50 of the nail gun is turned on, driving the transmission component 431 to rotate. During the rotation, the rotating part 4311 gradually engages with the tooth groove 4112 on the firing pin component 411, starting from the first toothed pin (movable toothed pin 4312'). This causes the firing pin component 411 and the piston component 412 to move in the opposite direction of the striking direction inside the inner cylinder 452. During the movement of the piston component 412, the volume of the second chamber 4522 gradually decreases, thereby compressing the gas in the air chamber 453. The air pressure in the air chamber 453 gradually increases to store energy. When the rotating part 4311 continues to rotate until a toothed state is formed between it and the firing pin component 411, the air pressure in the air chamber 452 pushes the piston component 412 and the firing pin component 411 out along the striking direction, thereby allowing the firing pin component 411 to fire the nail and complete the nailing operation.

[0092] During the rotation of the rotating part 4311, the ratchet also rotates along with the rotating part 4311. The pawl 4321 and the ratchet teeth 4331 on the outer periphery of the ratchet cooperate with each other to prevent the ratchet from reversing, thereby effectively avoiding the accidental firing of the striking pin part during operation and enhancing safety.

[0093] The method for replacing the firing pin component in this embodiment is as follows: When the nail gun is not in operation, first remove the nail storage device 30 and the housing 21, then remove the pressure relief component 47 to release the pressure inside the air chamber 453, then remove the rear cover 4512 on the rear side of the outer cylinder body 4511, take out the striking component 41 located inside the inner cylinder body 452, and replace the firing pin component 411; at the same time, if the transmission component 431 also needs to be replaced, then remove the transmission component 431 and replace it, then install the striking component 41 into the inner cylinder body 452, cover the rear cover 4512, then connect the inflation device to the inflation component 46 to inflate the air chamber 453, after inflation is completed, reinstall the housing 21, and install the corresponding nail storage device 30 to continue nailing.

[0094] Functions and effects of the embodiments

[0095] According to the driving device for the nail gun in this embodiment, since a limiting part that cooperates with the limiting part 432 for limiting the movement of the firing pin part 411 is directly provided on the transmission part 431, there is no need to provide a separate structure on the firing pin part 411 that cooperates with the limiting part 432, which simplifies the structure of the firing pin part 411. Furthermore, since there is no direct contact between the limiting part 432 and the firing pin part 411, there is no need to release the limiting relationship between the limiting parts 432 when the firing pin part 411 fires. That is, there is no need to provide a driving device such as a solenoid valve that is specially used to drive the rotation of the limiting part 432 at the limiting part 432, which simplifies the structure, reduces costs, and also solves the defects caused by the failure of the solenoid valve, making the entire nail gun more efficient, stable and safe when working.

[0096] In addition, since the volume of the air chamber is V1 when the striking component 41 is in the low energy storage position and V2 when the striking component is in the high energy storage position, the difference between the air chamber volume in the high energy storage position and the air chamber volume in the low energy storage position, V1-V2, is approximately equal to or equal to 1 / 3*V2. This difference is actually the volume of the area that the striking component moves from the low energy storage position to the high energy storage position inside the inner cylinder. This volume accounts for a large proportion of the entire energy storage component. That is, by increasing the volume of the inner cylinder, the energy consumption of the entire gun body is reduced during operation, and the requirements for the motor and battery of the lithium-ion nail gun are reduced, realizing the miniaturization and weight reduction of the lithium-ion nail gun, which can reduce the cost.

[0097] In this embodiment, the transmission component 431 includes a rotating part 4311 and a mating part. The rotating part is connected to the drive motor of the nail gun and is driven to rotate by the drive motor. The mating part consists of several toothed pins 4312 distributed on the rotating part. The toothed pins 4312 engage with the toothed grooves 4112 of the firing pin component 411, thereby realizing the engagement between the transmission component 431 and the firing pin component 411 and driving the firing pin component 411 to move. Compared with the engagement of gears and racks, the engagement of the toothed pins 4312 and the toothed grooves 4112 is easier to mesh, thus making the transmission more stable.

[0098] In this embodiment, the limiting part 433 is a ratchet coaxially arranged with the rotating part, and has a plurality of ratchet teeth 4331 on its outer periphery. The limiting component 432 is a pawl 4321 that cooperates with the ratchet teeth 4331 and is used to embed between adjacent ratchet teeth 4331. The ratchet is set to be coaxial with the rotating part 4311, so that the rotating part 4311 and the ratchet can rotate synchronously. The pawl 4321 cooperates with the ratchet to restrict the rotating part 4311 from rotating in the opposite direction, thereby restricting the movement of the impact pin component 411, improving safety. Moreover, the ratchet and the rotating part 4311 are directly driven by the same drive motor, eliminating the need for a separate power source, simplifying the structure, reducing costs, reducing weight, and making it convenient to carry and use.

[0099] In this embodiment, the spacing between the ratchet teeth 4331 on the ratchet is smaller than the width of the tooth groove 4112 on the impact pin component 411. Compared with the direct engagement of the pawl 4321 with the tooth groove 4112, the connection is more stable. The smaller the spacing, the tighter and more accurate the engagement of the pawl 4321, which greatly reduces or even eliminates the possibility of the pawl 4321 disengaging, thereby reducing the probability of the impact pin component 411 being misfired and improving safety performance.

[0100] In this embodiment, at least one of the toothed pins 4312 is a movable toothed pin 4312'. When the transmission component 431 and the firing pin component 411 cooperate with each other, the toothed pins 4312 need to be inserted into the toothed grooves 4112 one by one. In actual use, it is easy for the toothed pins 4312 and the toothed grooves 4112 to not be fully aligned, resulting in the toothed pins 4312 directly colliding with the toothed block 4111, failing to mesh properly and getting stuck. By setting the toothed pins 4312 to be movable, when the movable toothed pins 4312' collide with the toothed block 4111, the movable toothed pins 4312' will move slightly under the impact force, thereby accurately inserting into the toothed grooves 4112, avoiding the transmission component 431 and the firing pin component 411 from getting stuck, thus avoiding personal injury caused by the accidental firing of the nail due to the two getting stuck, and further enhancing safety.

[0101] The energy storage component of this embodiment includes two cylinders, an inner cylinder and an outer cylinder, with an air chamber between them. The inner cylinder 452 is located inside the outer cylinder body 4511 of the outer cylinder 451. A striking component 41 is installed inside the inner cylinder 452. The striking component 41 is driven by a drive component 43 to change the air pressure in the air chamber to drive the nail. A detachable rear cover 4512 is provided on the rear side of the outer cylinder body 4511 to facilitate disassembly for maintenance or replacement of the striking component 41 located inside the inner cylinder 452.

[0102] In this embodiment, the energy storage component 42 is equipped with a pressure relief component 47 leading to the air chamber 453. The pressure relief component 47 is an automatic pressure relief valve. When the air pressure in the air chamber 453 increases and exceeds a preset safety threshold, the pressure relief component 47 will automatically open to relieve pressure in the air chamber 453, so that the air pressure in the air chamber can always be kept within the safety threshold, ensuring the safety performance of the equipment. At the same time, the energy storage component 42 is also equipped with an inflation component 46 leading to the air chamber 453, which can inflate the air chamber 453 when needed, which is very convenient.

[0103] In this embodiment, the outer cylinder 451 of the energy storage component is integrally formed with a mounting portion 4519. The mounting portion 4519 is used to install a transmission component 431 that can drive the striking component to move in the opposite linear direction along the striking direction. The mounting portion 4519 is made into a universal component. When different gun needles are needed, only the appropriate firing pin component 411 (the striking component has a firing pin component and a piston component) and transmission component 431 need to be replaced, without replacing the entire device, which is highly applicable. When users need to perform construction in various situations, they do not need to carry various nail guns with different types of nails. They only need to carry the appropriate firing pin component and transmission component, which is very convenient to carry. In addition, since this embodiment is equipped with a pressure relief component and an inflation component, when the user needs to replace the firing pin, the pressure relief component can be removed first to release the gas inside the air chamber, then the rear cover can be disassembled to remove the piston and firing pin, and finally the firing pin can be replaced and reinstalled. The air chamber can then be inflated again through the inflation component for continued use. If the outer casing is disassembled directly without first depressurizing and venting the air chamber, it can easily cause the firing pin to be accidentally fired. Therefore, the depressurization component can also serve as a safety component to improve the safety of the equipment.

[0104] Because a positioning ring is provided between the inner cylinder and the outer cylinder body in this embodiment, two support points are formed between the inner cylinder and the outer cylinder body. One support point is where the inner cylinder and the outer cylinder body are fixed, and the other support point is where the positioning ring is located. The two support points provide more stable support for the inner cylinder and prevent the inner cylinder from detaching from the outer cylinder body and causing damage.

[0105] The above embodiments are only used to illustrate the specific implementation of this embodiment, and the present invention is not limited to the scope of the description of the above embodiments.
