Description

[Technical field]

[0001] The present application relates to a nail gun, belonging to the technical field of electric tools. [Background technology]

[0002] Nail guns are widely used in the decoration industry. According to the different driving sources, nail guns can be divided into electric nail guns, pneumatic nail guns, gas nail guns, manual nail guns, etc. At present, the electric nail guns on the market use gas as the power source. Their cylinder types are piston cylinders and plunger cylinders (nitrogen springs). The lifting mechanism drives the piston rod or plunger rod to move linearly in the cylinder body under the action of the driving mechanism. Therefore, the lifting mechanism directly affects the accessibility and human-machine coordination of the nail gun. It is specifically reflected in the weight and volume of the nail gun.

[0003] A typical example is that a circular guide rail is provided to guide the moving path of the lifting mechanism, but the circular guide rail cannot solve the problem of excessive radial width, which results in a larger nail gun volume and affects the accessibility of the nail gun; another example is that an X-shaped guide rail and a double gear structure are provided to guide the moving path of the lifting mechanism, but it is often superimposed with multiple layers of transmission mechanisms, which results in an increase in the volume and weight of the nail gun. In addition, due to the complexity of the transmission structure, it is easy to cause large errors in the later manufacturing and assembly, which affects the performance of the nail gun and the user experience.

[0004] Therefore, it is necessary to improve the prior art to overcome the above defects in the prior art. [Summary of the invention]

[0050] In order to make the above-mentioned purposes, features and advantages of the present application more obvious and easy to understand, the specific implementation methods of the present application are described in detail below in conjunction with the accompanying drawings. It is to be understood that the specific embodiments described herein are only used to explain the present application, rather than to limit the present application. It should also be noted that, for ease of description, only some structures related to the present application are shown in the accompanying drawings, rather than all structures. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0051] The terms "including" and "having" and any variations thereof in this application are intended to cover non-exclusive inclusions. For example, a process, method, system, product or device comprising a series of steps or units is not limited to the listed steps or units, but may optionally include steps or units not listed, or may optionally include other steps or units inherent to these processes, methods, products or devices.

[0052] Reference to "embodiments" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present application. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0053] See also Figures 1 to 23 As shown, a nail gun 100 in a preferred embodiment of the present application is generally used in construction scenarios to drive fasteners such as nails, tacks, staples, etc. into a workpiece to fix the workpiece. The present application does not specifically limit the application scenario of the nail gun 100.

[0054] See also Figure 1 The nail gun 100 includes a housing 10, an energy storage mechanism 20 disposed in the housing 10, a driving mechanism 60, a motor 30, and a striking mechanism 50 at least partially disposed in the housing 10. The housing 10 may be made of plastic, metal, etc., which is not specifically limited here and depends on actual conditions.

[0055] The housing 10 includes a main housing for accommodating at least part of the energy storage mechanism 20 and the driving mechanism 60, and a gripping housing connected to the main housing for holding, wherein the gripping housing is used to accommodate wires for convenient layout. One end of the gripping housing is connected to the main housing, and the other end is connected to the nail box 70 to form a "D" shape, which is convenient for users to hold.

[0056] In order to prevent the user from slipping during the holding process, an anti-slip part may be provided on the holding shell. The anti-slip part may be a rubber part mounted on the holding shell, or a convex point protruding outward from the outer surface of the holding shell. There is no specific limitation here and it depends on the actual situation.

[0057] The main housing is generally divided into at least two parts, and the two main housings are assembled to form a receiving chamber, and the energy storage mechanism 20, the driving mechanism 60 and at least part of the striking mechanism 50 are received in the receiving chamber, so that when the components in the main housing fail, the main housing can be easily disassembled to repair and replace the components. The connection between the at least two main housings can be achieved by snapping, bonding, welding or fastener connection.

[0058] The energy storage mechanism 20 is used to store energy and then drive the striking mechanism 50 to fire, so that the striking mechanism 50 has a strong impact force in an instant, and then the fastener can be hit into the target. It is generally a structure such as a cylinder. However, the volume of the cylinder is relatively large, and the energy storage mechanism 20 is arranged in the housing 10, which will correspondingly increase the overall volume of the housing 10. Therefore, in order to prevent the volume of the housing 10 from increasing, in this embodiment, the energy storage mechanism 20 is a nitrogen spring, which has the characteristics of small volume, large elasticity and impact force.

[0059] Please combine Figure 1 and Figure 2 Specifically, the nitrogen spring generally includes a cylinder 201 disposed in a housing, gas filled in the cylinder 201, a plunger 202 moving relative to the cylinder 201, and a seal disposed between the cylinder 201 and the plunger 202 and fixed relative to the cylinder 201. The cylinder 201 is provided with a first port 2011 and a second port 2012 away from the first port 2011, wherein the first port 2011 is disposed close to the striking mechanism 50.

[0060] The striking mechanism 50 includes a striking piece 501 for firing the fastener and a connecting seat 502 for connecting the striking piece 501 and the plunger 202. The connecting seat 502 is provided with mounting holes on both sides to engage with the striking piece 501 and the plunger 202 to achieve a stable connection. Of course, in other embodiments, the striking piece 501 and the plunger 202 can also be connected to the connecting seat 502 by welding or other methods, which can also achieve a stable connection. This is not specifically limited here and depends on the actual situation. Among them, the striking piece 501 is a firing pin.

[0061] Please combine Fig.10 and Fig.12 The connection seat 502 has an initial position A set away from the cylinder body 201 and an energy storage position B set close to the cylinder body 201. The driving mechanism 60 drives the connection seat 502 to move from the initial position A to the energy storage position B, so that the plunger 202 moves from the first port 2011 to the second port 2012, and then compresses the gas to achieve the effect of energy storage. It is worth noting that after the driving mechanism 60 drives the connection seat 502 to reach the energy storage position B, the driving mechanism 60 continues to move to disengage from the connection seat 502, so that the plunger 202 moves rapidly toward the first port 2011 under the action of the compressed gas, and then drives the striking member 501 to move in a direction away from the first port 2011 to achieve the nailing action.

[0062] Please combine Figure 6 In order to prevent the connection seat 502 from flipping under the action of the driving mechanism 60, thereby improving the stability of the movement of the connection seat 502, the connection seat 502 is provided with a matching surface 5021 that abuts against the driving mechanism 60. The matching surface 5021 is set as an arc surface, and the center of the circle corresponding to the arc surface is located on the center line of the striking member 501. The purpose of this setting is to make the connection seat 502 always point to the center of the plunger 202 when it is impacted, prevent the plunger 202 from generating lateral force, avoid the occurrence of the flipping phenomenon of the plunger 202, and improve the stability of the energy storage mechanism 20. Among them, the arc surface is set in a direction away from the first port 2011.

[0063] Specifically, the connection seat 502 includes a main body 5022 fixedly connected to the striking member 501 and an abutting portion 5023 connected to the main body 5022, and a mounting hole is provided on the main body 5022. It is worth noting that the mounting holes on both sides are not provided through. That is, the mounting holes on both sides are not connected to prevent the striking member 501 and the plunger 202 from connecting, and the connection seat 502 can move along the circumferential direction of the striking member 501 and the plunger 202 through the mounting hole, thereby improving the overall performance of the nail gun 100.

[0064] Please combine Figure 7The abutting portion 5023 has a first end 5024 and a second end 5025 that are arranged opposite to each other, and at least part of the driving mechanism 60 moves between the first end 5024 and the second end 5025. Figures 10 to 12 , taking the example of driving the connection seat 502 to move from the initial position A to the energy storage position B. Specifically, when at least part of the driving mechanism 60 moves from the first end 5024 to the second end 5025, the connection seat 502 moves from the initial position A to the energy storage position B, and the moving distance is half of the distance between the initial position A and the energy storage position B; when at least part of the driving mechanism 60 moves from the second end 5025 to the first end 5024 again, at least part of the driving mechanism 60 continues to move toward the energy storage position B until reaching the energy storage position B, and the moving distance is also half of the distance between the initial position A and the energy storage position B, so that the gas in the cylinder 201 can be compressed to the limit. The purpose of such a setting is to facilitate the abutment between the driving mechanism 60 and the abutment portion 5023, and at the same time, it can also reduce the length of the abutment portion 5023, thereby reducing the width of the housing 10.

[0065] Please combine Figures 1 to 3 The motor 30 is connected to the driving mechanism 60, so that the driving mechanism 60 moves, and then the driving mechanism 60 drives the connecting seat 502 to move to drive the striking member 501 to perform linear motion. The nail gun 100 also includes a reduction box 40 connected to the motor 30, and the reduction box 40 is used to adjust the high speed of the motor 30 to a set speed. In the height direction of the nail gun 100, the motor 30 is located below the reduction box 40. The reduction box 40 has an output shaft, and the output shaft is connected to the driving mechanism 60.

[0066] As mentioned above, because the connecting seat 502 drives the plunger 202 to perform linear reciprocating motion under the action of the driving mechanism 60, the connecting seat 502 also performs linear motion accordingly. The above-mentioned linear motion is along the length direction of the casing 10, and therefore, will not affect the width direction of the casing 10. Therefore, the volume, weight and motion trajectory of the driving mechanism 60 play a key role in the size of the casing 10. When the motion trajectory of the driving mechanism 60 in the length direction of the casing 10 remains unchanged, the larger the moving range of the driving mechanism 60 in the width direction of the casing 10, the larger the width of the casing 10. Among them, the length direction of the casing 10 is the first linear direction in which the connecting seat 502 performs linear reciprocating motion under the drive of the driving mechanism 60, and the width direction of the casing 10 is a direction orthogonal to the first linear direction, that is, the second linear direction.

[0067] The driving mechanism 60 includes a driving member 601 that can be selectively connected or separated from the connecting seat 502. When the connecting seat 502 is in the initial position A, the driving member 601 can be connected with the connecting seat 502 and drive the connecting seat 502 to move toward the energy storage position B; when the connecting seat 502 moves to (i.e. reaches) the energy storage position B, or when the connecting seat 502 passes the energy storage position B, the driving member 601 can be separated from the connecting seat 502, and at this time, the plunger 202 drives the connecting seat 502 to move toward the fastener under the action of the compressed gas, thereby driving the fastener into the target object.

[0068] As described above, the driving member 601 and the abutting portion 5023 can be selectively matched or separated. When the driving member 601 drives the connecting seat 502 to move from the initial position A to the energy storage position B, the driving member 601 first moves from the first end 5024 of the abutting portion 5023 of the connecting seat 502 to the second end 5025, and then moves from the second end 5025 to the first end 5024. The driving member 601 continues to move and is separated from the connecting seat 502 from the first end 5024, and the connecting seat 502 moves from the energy storage position B to the initial position A. That is, when the driving member 601 is matched with the connecting seat 502, it reciprocates on the abutting portion 5023 of the connecting seat 502.

[0069] In the process of the connection seat 502 moving from the initial position A to the energy storage position B, the driving member 601 has a first moving distance in the first linear direction and a second moving distance in the second linear direction, and the second moving distance is smaller than the first moving distance. The first linear direction is consistent with the linear reciprocating motion direction. As mentioned above, the first moving distance is the distance between the initial position A and the energy storage position B, and the second moving distance is the distance formed when the driving member 601 is in reciprocating motion with the abutment portion 5023. By making the second moving distance smaller than the first moving distance, so that the moving distance of the driving member 601 in the second linear direction (i.e., the width of the housing 10) is small, the purpose of reducing the width of the housing 10 can be achieved, and then the overall volume of the nail gun 100 can be reduced, thereby ensuring the accessibility and human-machine coordination of the nail gun 100.

[0070] In order to guide the movement direction of the driving mechanism 60, so that the driving mechanism 60 can smoothly drive the connecting seat 502 to drive the plunger 202, and prevent the connecting seat 502 from being deflected or flipped under the drive of the driving mechanism 60, the driving mechanism 60 also includes a guide assembly 602. The guide assembly 602 is arranged in the housing to guide the movement direction of the driving member 601, so that the driving member 601 moves along the guide assembly 602 and then drives the connecting seat 502 to move from the initial position A to the energy storage position B.

[0071] The guide assembly 602 in the present application includes a guide member 6021 connected to the driving member 601, and a guide portion 6022 fixedly arranged relative to the housing 10, and the guide member 6021 and the guide portion 6022 cooperate with each other to provide guidance for the movement of the driving member 601. Among them, the guide member 6021 has a first preset displacement in the first linear direction of the connecting seat 502, and has a second preset displacement in the second linear direction. In order to ensure that the width of the housing 10 is not increased, the second preset displacement is smaller than the first preset displacement. As mentioned above, the first preset displacement is the distance between the initial position A and the energy storage position B. At the same time, the second preset displacement is smaller than the minimum width of the housing 10 surrounded by the outside of the driving mechanism 60. The purpose of such a setting is to enable the housing 10 to be arranged along its minimum width, and the overall volume and movement distance of the driving mechanism 60 will not affect the width of the housing 10, thereby achieving the purpose of reducing the width of the housing 10, and then ensuring the accessibility and human-machine coordination of the nail gun 100.

[0072] Please combine Fig.21 and Fig. 22 , one of the guide member 6021 and the guide portion 6022 can be configured as a guide groove 6022, and the other of the guide member 6021 and the guide portion 6022 can be configured as a guide rod matched with the guide groove 6022, and the guide rod and the guide groove 6022 are slidably matched. In this embodiment, the guide portion 6022 is configured as a guide groove 6022, which further ensures that the width of the housing 10 will not be increased. The guide groove 6022 is elliptical, and the elliptical guide groove 6022 has a long diameter a and a short diameter b, the long diameter a corresponds to the first linear direction of the connecting seat 502, and the short diameter b corresponds to the second linear direction orthogonal to the first linear direction. Among them, the short diameter b is set along the width direction of the housing 10, thereby limiting the movement range of the driving mechanism 60 in the width direction of the housing 10.

[0073] The long diameter a is greater than or equal to the distance between the initial position A and the energy storage position B. When the driving mechanism 60 moves along the long diameter a, it can drive the connecting seat 502 to drive the plunger 202 to compress the gas to a certain position.

[0074] In one embodiment, the driving member 601 includes a body 6011 and a driving rod 6012 connected to the body 6011. The driving rod 6012 and the connecting seat 502 can be selectively matched or separated, and the guide member 6021 and the driving rod 6012 are arranged on both sides of the body 6011 opposite to each other. In this embodiment, the guide member 6021 is arranged near the end of the driving member 601, thereby reducing the overall length of the driving member 601, so that when the driving member 601 is controlled to rotate in the width direction of the housing 10, the overall width of the driving member 601 is also smaller than the minimum width of the housing 10 surrounding the outside of the driving mechanism 60, thereby minimizing the width of the housing 10. In addition, since the guide groove 6022 is elliptical, the diameter of the elliptical guide groove 6022 will change. When the driving member 601 slides along the guide groove 6022 through the guide member 6021 , the two guide members 6021 will restrict the driving member 601 from moving on the guide groove 6022 , so only one guide member 6021 is required.

[0075] The driving rod 6012 abuts against the abutting portion 5023 of the connecting seat 502, and drives the connecting seat 502 to move from the initial position A to the energy storage position B in a first time period, and is separated from the abutting portion 5023 in a second time period to cause the striking member 501 to fire. The first time period is the time for the connecting seat 502 to move from the initial position A to the energy storage position B, and the second time period is the time for the connecting seat 502 to move from the energy storage position B to the initial position A after the abutting portion 5023 is separated from the driving rod 6012.

[0076] Please combine Figure 4 , Figure 21 to Figure 23 Similarly, the driving rod 6012 is arranged at the end of the driving member 601 to reduce the overall length of the driving member 601, so that when the driving member 601 is controlled to rotate in the width direction of the housing 10, the width of the driving member 601 is also smaller than the minimum width of the housing 10 surrounding the outside of the driving mechanism 60, thereby minimizing the width of the housing 10. In order to facilitate the movement of the driving rod 6012, the driving rod 6012 has a supporting surface 6013, which is also a curved surface.

[0077] Adaptability can be achieved according to actual needs, for example, to ensure the stability between the driving rod 6012 and the abutting portion 5023, the friction between the driving rod 6012 and the abutting portion 5023 can be enhanced, and the friction does not affect the movement of the driving rod 6012 on the abutting portion 5023. The increase in friction can be achieved by adding a bump or a groove on the abutting surface 6013 of the driving rod 6012, which is not specifically limited here and depends on actual conditions.

[0078] In order to ensure that the motor 30 does not affect the width of the housing 10 and increase the width of the housing 10 when driving the body 6011 to move, the driving mechanism 60 further includes a limiter 603 for limiting the moving range of the driving member 601 .

[0079] There is at least one stopper 603, and at least one stopper 603 is disposed on one side of the driving member 601. Figures 3 to 5 The output shaft of the reduction gearbox 40 is connected to the limiting member 603 to drive the limiting member 603 to rotate, and then drives the driving member 601 to rotate.

[0080] The stopper 603 is provided with a protrusion 6031, which is arranged toward the direction of the reduction box 40 and then docked with the output shaft of the reduction box 40, so as to drive the stopper 603 to move under the drive of the motor 30. The movement of the stopper 603 drives the movement of the driving member 601, thereby driving the connecting seat 502.

[0081] The limiting member 603 and the driving member 601 are clamped to enable the driving member 601 to move with the limiting member 603. Specifically, a limiting groove 6032 is provided on one of the driving member 601 and the limiting member 603, and a limiting block 6014 cooperating with the limiting groove 6032 is provided on the other of the driving member 601 and the limiting member 603, and the diameter of the limiting groove 6032 is greater than the diameter of the limiting block 6014. The purpose of such arrangement is that: the guide groove 6022 is elliptical, and the driving member 601 will generate horizontal displacement during the movement along the guide groove 6022. When the driving member 601 and the limiting member 603 move from the long diameter a of the guide groove 6022 to the short diameter b of the guide groove 6022, the limiting block 6014 can move in the limiting groove 6032, and then will not affect the movement of the driving member 601. In this embodiment, a limiting block 6014 is provided on the driving member 601, and a limiting groove 6032 is provided on the limiting member 603. The specific positions of the limiting block 6014 and the limiting groove 6032 are not limited, as long as the purpose of clamping is achieved.

[0082] The stopper 603 located at least on one side of the driving member 601 can be arranged below the driving member 601 or above the driving member 601. When the stopper 603 is located below the driving member 601, a connection block connected to the driving member 601 needs to be arranged on the upper surface of the stopper 603, which increases the structural complexity of the stopper 603 and the overall weight of the driving mechanism 60. Therefore, in this embodiment, the stopper 603 is arranged above the driving member 601.

[0083] Because the protrusion 6031 is connected to the output shaft of the reduction box 40, the protrusion 6031 is arranged downward in the height direction of the nail gun 100. Therefore, a first notch 6015 is provided on the driving member 601 to accommodate the protrusion 6031. The diameter of the first notch 6015 is larger than the diameter of the protrusion 6031, so that the driving member 601 can move in the horizontal direction relative to the limiter 603. The purpose of such arrangement is that when the driving member 601 moves from one end of the long diameter a of the elliptical guide groove 6022 to one end of the short diameter b, the driving member 601 will move in the horizontal direction due to the cooperation between the guide member 6021 and the guide groove 6022, and the arrangement of the first notch 6015 can enable the driving member 601 to move in the horizontal direction.

[0084] In order to better achieve the cooperation between the guide member 6021 and the guide groove 6022, in this embodiment, two limit members 603 are provided, and the two limit members 603 are respectively provided on both sides of the driving member 601. At this time, the limit member 603 located below the driving member 601 is provided with a second notch 6033 for accommodating the protrusion 6031, and the diameter of the second notch 6033 is larger than the diameter of the protrusion 6031, and the reason is the same as the first notch 6015 mentioned above, which will not be repeated here.

[0085] Furthermore, in order to enable the driving member 601 to rotate smoothly when it moves to the width direction of the housing 10, a receiving groove 6034 may be provided on one of the driving member 601 and the limiting member 603. At this time, the driving mechanism 60 further includes a ball 604, and the ball 604 at least partially protrudes out of the receiving groove 6034. Through the provision of the ball 604, the driving member 601 can slide smoothly on the limiting member 603, so as not to cause obstruction, thereby improving the overall stability of the nail gun 100. In this embodiment, the receiving groove 6034 is provided on the limiting member 603.

[0086] In another embodiment, the driving member 601 may be a telescopic rod, and the limiting member 603 may be a crank. One end of the crank is connected to the output shaft of the reduction box 40, and the other end is fixedly connected to the telescopic rod. At this time, the guide member 6021 is arranged on the telescopic rod. The crank rotates under the action of the reduction box 40 and the motor 30, and the guide member 6021 abuts against the abutment portion 5023 of the connecting seat 502. When the crank moves from one end of the major diameter a of the elliptical guide groove 6022 to one end of the square diameter b, the telescopic rod is converted from an extended state to a compressed state. When the crank moves from one end of the square diameter b of the elliptical guide groove 6022 to the other end of the major diameter a, the telescopic rod is restored from a compressed state to an extended state, and then the connecting seat 502 is driven so that the connecting seat 502 moves from the initial position A to the energy storage position B.

[0087] Please see again Figure 1The nail gun 100 is generally equipped with a nail magazine 70, which is arranged on a side of the main housing away from the grip housing. The nail magazine 70 includes a first magazine body fixedly connected to the main housing and a second magazine body detachably connected to the first magazine body. The purpose of such arrangement is that when there are not many or no nails in the nail magazine 70, the second magazine body can be removed to replace the nails, which is quick and convenient. Of course, in other embodiments, the nail magazine 70 can also be detachably connected to the main housing as a whole, and when the nails in the nail magazine 70 are used up, the nail magazine 70 can be replaced as a whole.

[0088] The power of the nail gun 100 is provided by electricity, so the nail gun 100 is generally provided with a power mechanism. The power mechanism can be a plug with a connecting wire, or a battery pack.

[0089] When the power mechanism is a plug with a connecting wire, it needs to be fixedly connected to the nail gun 100, thereby limiting the range of movement of the nail gun 100 when in use, but does not limit the power because it does not limit the use time of the nail gun 100.

[0090] When the power mechanism is a battery pack, the range of movement of the nail gun 100 during use is not limited, but the use time of the nail gun 100 is limited. Therefore, the battery pack can be detachably connected to the housing, and when the battery pack connected to the nail gun 100 is out of power, the battery pack can be removed and replaced with a fully charged battery pack, and the nail gun 100 can continue to be used, which is convenient and quick.

[0091] In summary, the drive member 601 and the guide assembly 602 are provided, which can be selectively connected or separated from the connection seat 502. The guide assembly 602 includes a guide member 6021 connected to the drive member 601 and a guide portion 6022 fixedly arranged relative to the housing 10. The guide portion 6022 and the guide member 6021 cooperate with each other to provide guidance for the movement of the drive member 601, so that the drive member 601 moves along a predetermined direction without deviation, and the overall movement is more stable. In addition, the structures of the guide assembly 602 and the drive member 601 are relatively simple, so as to achieve the effect of reducing the overall volume and weight of the nail gun 100. At the same time, Therefore, the preset displacement of the guide member 6021 in the first linear direction of the connecting seat 502 is greater than the preset displacement of the guide member 6021 in the second linear direction, thereby reducing the width of the housing 10 in the second linear direction, thereby ensuring the accessibility and human-machine coordination of the nail gun 100; and in the process of driving the connecting seat 502 to move from the initial position A to the energy storage position B, the moving distance of the driving member 601 in the first linear direction is set to be smaller than the moving distance of the driving member 601 in the second linear direction, thereby further reducing the width of the housing 10, and once again ensuring the accessibility and human-machine coordination of the nail gun 100.

[0092] The above is only a specific implementation of the present application, and any other improvements made based on the concept of the present application are deemed to be within the protection scope of the present application.
